Abstract

Due to the frequent occurrence of electric shock accidents in distribution lines, the difficulty of identifying electric shock fault phase has become an urgent problem to be solved. The active control method for preventing electric shock in distribution network is proposed. The topology structure of device which used active control method for preventing electric shock is established. On this basis, a new fault phase selection method considering the instantaneous value of three-phase voltage is proposed to realize rapid, accurate and active prevention of electric shock. Typical application scenarios of active control method for preventing electric shock are established. The optimal installation scheme is able to reduce the electric shock current from 3A to 0A within 4ms, and there is almost no oscillation in the transient process. The application scheme of active control method for preventing electric shock is made differentiated which decided by the key influencing factors.
