Protective electronic module for hvdc converter
FIELD: electricity.
SUBSTANCE: electronic module comprises a capacitor, a short-circuit device, a movable portion, a short-circuit portion and a spring element, a short-circuit device is in parallel connected to the capacitor, the short-circuit device comprises a first and a second bus, the movable portion is connected to the first bus, and the short-circuit portion is connected to the second bus, the spring element is located between the movable portion and the short-circuit portion, when the short-circuit current flows through the first bus, the magnetic force between two buses causes the first bus to be repelled from the second bus and moves towards the short-circuit portion.
EFFECT: providing the ability to protect the circuit from the discharge of energy originating from the capacitor.
