Abstract
This utility model discloses a compensation transformer apparatus with a function of anti-inverse-surge. An inputting end of compensating voltage is connected to a voltage regulation module providing compensating voltage U. The compensation transformer apparatus with a function of anti-inverse-surge comprises a compensation transformer for outputting the compensating voltage U in a superposition manner and an anti-inverse-surge circuit of the voltage regulation module (1) for preventing the compensation transformer from producing high voltage inverse surge when a circuit is started or the voltage regulation module performs a voltage regulation switch to change an output direction of the compensating voltage U. The anti-inverse-surge circuit is connected between two inputting ends of inputwinding in a parallel manner. The utility model enables the compensating voltage end of the compensation transformer and a resistance to form a return circuit by controlling a controllable switch when the circuit is started, thereby achieving an effect of anti-inverse-surge and preventing other members from being burnt.
