摘要： A leakage detection protection circuit with function of regular self-examination of separate elements comprises a power input port, a power user port, a power output port, a reset button, main loop switches, dual induction coils, a tripping coil, a silicon controlled rectifier, a control chip, and a regular self-examination circuit. The regular self-examination circuit includes a self-examination chip and a second silicon controlled rectifier. A trigger electrode of the silicon controlled rectifier is connected to a drive pin of the control chip and to an A/D conversion interface of the self-examination chip. An anode of the silicon controlled rectifier is connected to another A/D conversion interface of the self-examination chip. The self-examination chip has a processing module, which acquires electrical parameters of the drive pin of the control chip and electrical parameters of the anode of the silicon controlled rectifier and compares said electrical parameters with respective pre-determined parameters to determine whether the control chip and the silicon controlled rectifier are in a normal operating state.
