The invention discloses an electronic switch circuit and a track circuit. The electronic switch circuit comprises a first interface, a second interface, a switch module, a protection module and a relay control interface; the first interface is connected with the positive power receiving end of the first steel rail; the second interface is connected with the negative power receiving end of the second steel rail; the switch module is respectively connected with the first interface, the second interface and the relay control interface, and the switch module is used for controlling connection and disconnection between the second interface and the relay control interface according to a relative relation between a voltage value of the first interface and a first preset range; the protection module is connected with the first interface and the switch module and used for controlling the switch module and the relay control interface to be disconnected if the switch module has a short-circuit fault under the condition that the first steel rail and the second steel rail are short-circuited. According to the scheme, the reliability of the electronic switching circuit and the safety of the track can be improved.
本发明公开了一种电子开关电路和轨道电路。电子开关电路包括第一接口、第二接口、开关模块、保护模块和继电器控制接口;第一接口与第一钢轨的正受电端连接;第二接口与第二钢轨的负受电端连接;开关模块分别与第一接口、第二接口和继电器控制接口连接,开关模块用于根据第一接口的电压值与第一预设范围的相对关系控制第二接口与继电器控制接口之间的通断;保护模块分别与第一接口和开关模块连接,保护模块用于在第一钢轨和第二钢轨之间短路的情况下,若开关模块出现短路故障则控制开关模块与继电器控制接口之间的连接断开。本申请方案可以提高电子开关电路的可靠性和轨道的安全性。
