Title:
RAIL VEHICLE BUS BAR CIRCUIT BREAKER CONTROL CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2022/088260
Kind Code:
A1
Abstract:
A rail vehicle bus bar circuit breaker control circuit, comprising a closed relay (BHB_CLOSE), a breaking relay (BHB_OPEN), a power supply circuit of the bus bar circuit breaker (BHB), a power supply circuit of a latching relay (BHB_HOLD), and a delay module (RS). The power supply circuit of the latching relay (BHB_HOLD) comprises a normally closed contact (BHB_OPEN-1) of the breaking relay (BHB_OPEN), an auxiliary normally open contact (BHB-2) of the bus bar circuit breaker (BHB) and the latching relay (BHB_HOLD) which are sequentially connected in series to a train power supply. The power supply circuit of the bus bar circuit breaker (BHB) comprises a normally open contact (BHB_HOLD-1) of the latching relay (BHB_HOLD) and the bus bar circuit breaker (BHB) which are sequentially connected in series to the train power supply. The delay module (RS) and the latching relay (BHB_HOLD) are in parallel connection. The normally closed contacts of the delay module (RS-1, RS-2) are sequentially connected in series to the power supply circuit of the closed relay (BHB_CLOSE). A high-potential end of the closed relay (BHB_CLOSE) is connected to a high-potential end of the delay module (RS) via a normally open contact (BHB_CLOSE-1) of the closed relay (BHB_CLOSE). After the bus bar circuit breaker control circuit is applied, the vehicle can perform logical determination and automatically send instructions to force a closing or manually force a closing. Control devices in a bus bar circuit breaker box execute the instructions.
