| description | The utility model provides a two power supply switching circuit of railway signal electrical power generating system, include: first via circuit breaker, second way circuit breaker, first via ac contactor, second way ac contactor, two switching of power device, first via control circuit and second way control circuit: input the two switching of power devices of main contact connection that the power passed through first via circuit breaker, first via ac contactor in proper order all the way, two -way input power passes through second way circuit breaker, second way ac contactor's the two switching of power devices of main contact connection in proper order. Compared with the prior art, the utility model discloses has following advantage: improve the breaking capacity of disengagement failure input power, reduced I way, the II way input power probability of short circuit matter emergence in the twinkling of an eye, when the I way, when II way input power concurs the trouble, output is cut off the power supply |
