Device for changing voltage in "capacitive pump" network

FIELD: electricity.

SUBSTANCE: invention relates to electrical engineering and can be used for changing voltage in a network. The device for varying voltage in network is a connection of a set of capacitors or modified capacitor for "pumping" electrical energy from a network with "transformation" of supply voltage. Shortcomings related to manufacture of transformers, which require large material inputs and use of expensive raw material are excluded, as well as servicing and need for the user to settle for power, provided by the transformer substation or some other system for changing voltage. The device can be installed into an open line of the high side. Installation of a capacitor in the circuit leads to increase in cos φ, which is good for the circuit as a whole. The invention does not transform electrical energy, but pumps it out of the network, as it were. Pumping power depends on the capacitance of the device. Large capacitance is required for a high power user. Knowing the required power and voltage of the user and the high side, it is easy to calculate capacitors and standardise the proposed device as a whole. The device allows for considerable decrease in power used by the network due to that, the source of electrical energy supports voltage harmonics and not power in the network.

EFFECT: use of a capacitor as a transformer.

SUBSTANCE: each of capacitor units contains many base capacitors installed on special module printed-circuit board (PCB). All the base capacitors of capacitor units are identical, thus simplifying both manufacturing and maintenance of capacity component. Formation of composite capacity on base capacitors of the same type simplifies significantly their manufacturing and maintenance. Space flexibility achieved due to application of lots of electrically interconnected capacitor units is preferable in such power devices where capacity available to capacity component inside the device may be limited in at least one direction. Geometrically flexible arrangement provided by separate capacitor units allows their arrangement at random angle to each other thus occupying available space in power devices increasing their composite capacity.

SUBSTANCE: invention suggests a three-phase capacitor formed by two integrated cylinders, at that each cylinder has an outer part corresponding to the capacitors (1) and (2) and inner part of each cylinder, which correspond to cylinders (3) and (3') and which are wye-connected to phases (A), (B) and (C). Each capacitor is separated from the neighbouring capacitor in each cylinder by insulating material, which ensures movement of the inner part in regard to the outer part of each cylinder at high pressure, and the following occurs in case of this movement: disconnection of the above links made according to the method; breakage of the conductive coating (7), which joints armatures (3.1) and (1.2); breakage of the conductive coating (8), which joints armatures (2.2) and (3'.2); as well as breakage of the connecting wire (6) connected to the phase (C); thus the suggested structure serves as effective protection against inner pressure growth.

EFFECT: due to movement of the inner parts by sliding along the outer surface links are disconnected when inner pressure is increased, with the result that contact with outer capacitors is eliminated thus improving protection degree against inner pressure growth.
