Relay detects protection circuit

The utility model relates to a relay detects protection circuit, including the relay, still including the count module and the temperature sensing module that connect the relay, a treater MCU is connected respectively to count module and temperature sensing module's output, treater MCU's output connect display device, treater MCU's output is still connected the relay. The utility model discloses a reasonable setting of circuit, it goes on simultaneously to have realized that relay mechanical durability detects to detect with the temperature, and when relay mechanical durability and temperature reached certain limit value, the control relay broke off to output display information. This system has reduced dangerous incidence, has guaranteed the result of use and the safety of relay. 本实用新型涉及种继电器检测保护电路，包括继电器，还包括连接继电器的计数模块和温度传感模块，计数模块和温度传感模块的输出端分别连接处理器MCU，所述的处理器MCU的输出端连接显示装置，处理器MCU的输出端还连接所述的继电器。本实用新型通过电路的合理设置，实现了继电器机械寿命检测和温度检测同时进行，且当继电器机械寿命和温度达到定限值时，控制继电器断开，并输出显示信息。该系统降低了危险的发生率，保证了继电器的使用效果与安全。
