Abstract:
1. A device for detecting a state of a load overcurrent protector, comprising: an input module, configured to be connected with two ends of the load overcurrent protector, and generate two output signals respectively at two output ends thereof; a high level signal gating module, configured to receive the two output signals generated by the input module, and gate and output a high level signal according to the two output signals; a low level signal gating module, configured to receive the two output signals generated by the input module and gate and output a low level signal according to the two output signals; and a detecting module, configured to detect a voltage difference between the high level signal and the low level signal; a high level signal generating module, configured to replace the high level signal gating module, receive the two output signals generated by the input module, and generate a high level signal according to the two output signals; and a low level signal generating module, configured to replace the low level signal gating module, receive the two output signals generated by the input module, and generate a low level signal according to the two output signals; wherein when there is a voltage difference between said high level signal and said low level signal, it is reflected that the load overcurrent protector is in an abnormal state; when there is no voltage difference between said high level signal and said low level signal, it is reflected that the load overcurrent protector is in a normal state.
