Summary:The utility model discloses an anti-creeping device based on an optimized 500kV substation transformer gas relay, which relates to the technical field of anti-creeping protection and comprises a zero sequence current detection module, a signal conditioning module, a main control module, an alarm module, an electric leakage protection module and a communication module. The zero-sequence current detection module is used for detecting leakage current of a gas relay circuit, the signal conditioning module is used for rectifying an alternating current signal and taking an absolute value to filter and amplify the alternating current signal, the main control module is used for receiving a direct current signal and outputting a control signal, and the leakage protection module is used for controlling the gas relay to stop working. And the communication module is used for performing wireless data communication with a user side. According to the anti-creeping device for the gas relay of the transformer based on the opt
