Abstract

A reverse wiring self-protection circuit is disclosed, including an auxiliary power module configured to provide tripping electric energy for tripping the solid-state circuit breaker to a tripping coil of the solid-state circuit breaker before an isolating switch of the solid-state circuit breaker is closed; a reverse wiring determination module configured to determine whether DC power connected to the solid-state circuit breaker is reversely wired, and output a first driving enable signal enabling a driving circuit module in response to reverse wiring of the DC power; the driving circuit module is configured to, transmit a driving signal indicating tripping operation to the tripping coil, in response to the first driving enable signal. The reverse wiring self-protection circuit according to the present disclosure can protect the elements included in the solid-state circuit breaker itself and improve the personal safety of the DC system to which the solid-state circuit breaker is connected.
