FIELD: electricity. SUBSTANCE: invention is related to a device for components of high-voltage pulse testing system, preferably to quality control of high-power transformers. The invention concept is as follows: in the device for components of high-voltage pulse testing system containing a pulse generator and auxiliary components, and namely a limiting discharger (2), voltage divider (3) and overload compensator (4) at least two of the auxiliary components are installed on a common frame with the only main electrode (11) for auxiliary components. EFFECT: reducing spatial extension and number of galvanic connections. 6 cl, 2 dwg
The present invention relates to a device for components of high-voltage impulse test system, it is preferable to control the quality of power transformers. The high voltage test is aimed at the modeling of transient overvoltages in networks of three-phase current through artificially generated pulse beats. In this classical way to distinguish between external stresses caused, for example, lightning strikes, and internal switching overvoltages resulting from switching operations in the network. Many of the overvoltage phenomena with the purpose of the test is reduced to the standard voltage of lightning and switching impulse voltages. For these test voltages are determined by the parameters describing the stress increases, the peak value and the return within the specified tolerances. With limited pulse voltage, which should simulate the action is very rapid changes in voltage, as an additional parameter of type constraints. Requirements, forms voltage, and the determination of their parameters set in the ICE 60060-1. Depending on model tests of high-voltage impulse test system contains for this purpose, the pulse generator and auxiliary components, such as, for example, ogranichitel the th bit interval, the voltage divider and the pressurizer surge. To generate a desired pulse shock stresses on the market over the years, established the multiplication circuit Marx, also called the Marx generators. Switching type, developed by the same inventor in 1923 and patented under the number DE 455 933, consists of several stages of switching, each of the stages contains series-connected switching capacity and switching the body, in particular a switching spark gap, and connected in parallel to the pulse tank and to the switching body resistance, and the resistance included in series with them. Two cascaded stages are connected to each other so that they are charged in parallel and discharged in series connection. The pulse capacitor is charged with a constant voltage charging. With this is connected the charging resistance limit not only the charging current, but also allow short-term serial connection of the capacitors with the help of bit intervals. Bit of a distance based intervals are selected so that they are at the maximum voltage of the charge just still did not break. After all pulsed conden atory charged to its steady-state final value voltage, is burning low discharge gap, which then breaks. Then in the next bit period of the discharge voltage is doubled, so that it is ignited by guarantee. Regardless of the number of steps of the process of discharge in the sum of the voltage of the charge previously burned steps continues until the last step. Thus, pulses of shock voltage of very short duration and at the same time with a large amplitude, is suitable, in particular, for the purposes of tests and experiments in high voltage equipment, as well as to determine koordynowania isolation and noise immunity in electromagnetic compatibility. In addition, for example, from DE 196 39 023 known to increase the ultimate load capacity just described the Marx generator using switching consoles, for which the voltage on the load capacitance, i.e. the sample to be tested, during the overvoltage decreases, and after the termination of the surge rises again. Thus, switching the console, also called sequential pressurizer surge, does not eliminate the cause of the surge, and compensates for over-voltage on the load capacitance, i.e. in particular on the sample to be tested. The pressurizer surge contains the compensation tank and less is th least one parallel connected resistance discharge or one bit period, moreover, switching the console is included in the multiplication circuit Marx consistently with the test object. Along with the surge compensator, connected in series with the test object, is known for its parallel connection to the subject sample. In contrast to the just described design with the high performance of surge compensator compensating capacitance and at least one resistance discharge or one bit period included consistently. In addition, to simulate the operating load voltage and to determine the strength of high-voltage insulation of structural elements on a break, you must also, as mentioned above, to apply for the tested objects limited voltage shock pulse. For the successful completion of such a standard test requires that the applied voltage was interrupted within the tolerance desired time elapsed since the beginning of the waveform, of the order of several microseconds. Technically, this is implemented through restrictive bit intervals, has long been known from the prior art, for example, from DD 143 130. In addition, the test system pulse output a high voltage signal to the last stage of the multiplication circuit Marx along with the test object is connected also Molsky voltage divider with reduced capacity, that reduces the pulse arc voltage appearing at the discharge levels to values that can be processed by the measuring and recording devices. All these mounted components high-voltage impulse test system have a large spatial extent, and should be installed on the test site with the specified minimum intervals, depending on the voltage level. In addition, certain minimum voltage-dependent voltage must also be maintained between the elements under tension, and limit test site. Thus, the need for space is available for the entire high-voltage impulse test system is significant. In addition, many manufacturers of transformers for replacement of the test object you want to move the entire high-voltage impulse test system. In this case, the Marx generator and three other auxiliary component, you need to move around the room to test separately and again to mount and to equip high-voltage impulse test system again. This process is time-consuming and difficult to use. The present invention is to reduce the spatial extent of auxiliary components, the head of the generating from the voltage in particular bounding the discharge gap of the expansion joint of the surge voltage divider and thereby reducing the need for space is available for the entire high-voltage impulse test system so that the pavilion for testing could be exploited more effectively. In addition, the object of the invention is the reduction of the number of implemented galvanic connection, thereby saving time of the user in the construction of high-voltage impulse test system. This task is solved by a device for components of high-voltage impulse test system with the characteristics of the first claim. The dependent claims relate in particular to the preferred improved variants of the invention. The General idea of the invention consists in the replacement of the hitherto separate key frames and the corresponding head electrodes separate auxiliary components of the overall main frame with the total for all accessories head electrode. In addition, as the field connections for all accessories should serve as a common point of galvanic connections. Since the area of the connecting auxiliary components are United in one common point of connection they have in this is the field during the tests the same voltage level. Therefore, for operation of high voltage impulse test system now requires only one connection to the generator and one with the test object. In addition, due to the constructive integration of support components in one common main frame user's first opportunity to meet a longstanding demand of high-voltage impulse test system in relation to small need of space, easy transport and thereby in relation to the associated reduction of time for installation. The large extent of the high-voltage impulse test system area is still explained by the large and depends on the voltage specified intervals between the individual head electrodes of the respective subcomponents. However, to replace these several separate head electrodes with one electrode on the main frame and, in addition, for the spatial Association of auxiliary components in a single main frame needed a solution with the following technical problems. In the joint spatial layout of auxiliary components have additional parasitic capacitance, a negative impact on the accuracy of the voltage divider. When this voltage divider has n the tunable thus, to these measurements, despite the presence of large stray capacitance, high precision. This is according to the invention, on the one hand, achieved a certain spatial location of auxiliary components, so that the parasitic capacitive effects become negligible, on the other hand, the strict definition of containers used inside auxiliary components, so that the resulting total capacity allowed accurate measurement, and, in addition, the correct choice of capacity and resistance of the voltage divider. However, due to the lack of linear dependencies between the above-mentioned control possibilities in the literature to define the parameters are only approximate models, which leads to the fact that the value of the stray capacitance must be assessed through simulation. This simulation is verified in the subsequent experimental designs; therefore, all of this is an iterative process. In addition, to effectively curb the occurrence of breakdown voltage occurring electromagnetic fields should dissipate by the appropriate joint layout auxiliary components. In particular, the burning of restrictive discharge gap is associated with a complex transition process. When this bit restrictive prom is terrible in a short time has zero potential, while other auxiliary components through their own tanks are still under great stress. Therefore, the regulation of the field should be optimized enough to prevent the breakdown voltage between the voltage divider and restrictive bit range, or the pressurizer surge and restrictive bit interval, which requires seamlessly calculation field. However, as with most programs, field calculation calculation yields only a landline and not a transitional case greatly varying fields, requiring an iterative process between modeling and design implementation. This was preferred mutual electrical shielding of the pressurizer surge and voltage divider by means of additional toroids. However, in the original edition 3.62/4 applicant first became known integration restrictive discharge gap with a voltage divider for short commuting shock pulses, but only in this device, both the auxiliary component may not be used, as in the present invention, synchronously. Restrictive bit intervals, known from the prior art usually have, among other things, a column consisting of a combination of resistance, good discharge performance is th and tanks and, thus, the same structural elements as voltage dividers with reduced capacity. If the bit period is not burned, it is possible to give a bit restrictive interval function of the voltage divider. However at the conclusion from the opposite it also means that if the surge voltage is limited, i.e. the bit period is ignited, the test should be additional voltage divider. Solutions of spatial Association auxiliary components this signature edition is not offered. In addition, in the framework of the invention it is possible to spatially combine in a common base frame only two of the three possible auxiliary components, as, for example, the use of the compensator surge is not considered as functionally necessary and appropriate only as improving the quality of the generated short-term impact stresses. Possible different combination of auxiliary components. Below the invention is explained in more detail with reference to the drawings, in which Fig. 1 depicts schematically a device for components of high-voltage impulse test system according to the invention, Fig. 2A and 2b depict a preferred embodiment of the device for components of high-voltage pulse is of istemi tests according to the invention. In Fig. 1 shows the main frame 1 according to the invention for mounting auxiliary components, such as bit restrictive period 2, the divider 3 voltage or compensator 4 overvoltage. Auxiliary components in Fig. 1 reasons of clarity, shown only schematically. While the main frame for reliable installation has, for example, a triangular bottom region of interconnected steel tubes 5, 6 and 7. Restrictive bit period 2, the voltage divider 3 and the compensator 4 surge arresters are installed at the respective corners of the main frame 1 and have with it a conducting connection. In addition, the upper ends of the respective auxiliary component is mechanically fixed by means of electrically conductive cross bars 8, 9 and 10. In turn, the strut 8, 9 and 10 is connected to the head electrode 11, which may be performed, for example, in the form of a toroid. The conductive cross-beams 8, 9 and 10 thereby perform the task as mechanical retention of the head electrode 11 and equipotential bonding auxiliary components and the downstream electrode 11. Head electrode 11 is depicted in the exemplary embodiment is designed so that the outer circumference overlaps the auxiliary components that are installed on respective corners. However, this calculation may WA gorovtsa depending on the respective application, the distance to the wall or ceiling of the test room and therefore be calculated only for example. In the framework of the invention it is possible to fix in the respective corners of the triangular bottom two out of three possible auxiliary components or, on the other hand, to modify the design of the main frame 1 according to the invention in the calculation only on the two receiving devices for the auxiliary components. In addition, auxiliary components are electrically interconnected through a common connection point in the field of conducting cross-beams 8, 9 and 10 and thus have in this area the same potential. In Fig. 2A and 2b depict a preferred embodiment of the invention, wherein the bottom region of the main frame 1 in contrast to Fig. 1 has not triangular and elongated, i.e. linear. Additional console 12, 13 and 14, mounted on the sides of the main frame 1, ensure reliable mounting of the modified frame construction. For this line of perform is that it may be performed with receiving devices only for two auxiliary components. Thus, the General inventive idea of this proposal should include all embodiments of the main frame, which allow you to replace the hitherto separate main R who we and the relevant head electrodes separate auxiliary components of the overall base frame common to all of the auxiliary components of the main electrode. 1.
