A power supply device for ground sensing in a railway locomotive signal machine is characterized by comprising a one-way power supply module, the one-way power supply module is connected with a ground sensor in series, and the one-way power supply module is connected with a signal lamp power supply in parallel. According to the invention, the designed one-way power supply module is used for replacing a transmission mode of a current transformer adopted in an original circuit, and compared with an original direct-current output current transformer, the one-way power supply module is longer in service life, smaller in overall size and smaller in occupied space of a signal machine; the unidirectional power supply module supplies power to the ground inductor and is connected in parallel with the signal lamp power supply, so that the voltage of the ground inductor is not influenced by the power supply of the signal lamp in the prior art, stable output of the voltage is still maintained, and stability of the voltage of the ground inductor is indirectly maintained; and when the signal lamp power supply still works normally, the voltage still can be stably output, and the stability of the ground induction voltage is indirectly maintained.
一种铁路机车信号机中的地感用供电装置,其特征在于包括单向电源模块,所述单向电源模块与地面感应器串联连接,所述单向电源模块与信号灯电源并联连接,本发明通过设计的单向电源模块来代替原本电路中采用的电流互感器的传输方式,相较于原本直流输出的电流互感器,单向电源模块的使用寿命较长,且整体体积较小,占用信号机的空间较少;本发明设计的单向电源模块为地面感应器供电,且其与信号灯电源并联连接,使得地面感应器电压不再受以往因信号灯供电的影响,依旧保持电压的稳定输出,间接保持地面感应器电压的稳定,若是信号灯出现损坏,而信号灯电源依旧正常工作时电压依旧可以保持稳定输出,间接保持地感电压的稳定。
