Background
The residual current operated protective device is divided into an electronic type and an electromagnetic type according to different tripping modes. The electromagnetic trip type residual current action protection device takes an electromagnetic trip as an intermediate mechanism, when leakage current is found, the output voltage of a secondary loop of a zero line current transformer is not amplified, the residual current trip is directly excited to trip the mechanism and disconnect a power supply, and the action function of the electromagnetic trip type residual current action protection device is unrelated to line voltage. Its advantages are high anti-interference power and high resistance to over-current and over-voltage. No auxiliary power supply is needed, and the zero voltage and the leakage characteristic after phase failure are unchanged. The electromagnetic earth leakage circuit breaker has many advantages, but the manufacturing process is complex, and the cost is high, so the electromagnetic earth leakage circuit breaker is only widely used abroad at present.
The electronic residual current action protection device takes a transistor amplifier as a middle mechanism, an electronic amplifier circuit is connected between a secondary circuit of a zero line current transformer and a tripper, and when leakage current is found, the output voltage of the secondary circuit of the transformer is amplified by the electronic circuit and then excites the residual current tripper to trigger the tripper mechanism of a circuit breaker to cut off a power supply. Its action function is related to line voltage, and the interference killing feature is poor, and the earth leakage protector can lose the protect function when the main loop lacks the phase. The electronic leakage protection circuit breaker has simple manufacturing process and low cost, and is widely used in China.

However, to date, there is no such product on the market. The electromagnetic release directly stimulates the residual current release to directly push the ejector rod frame by utilizing the secondary loop output voltage of the zero line current transformer without any amplification, and the thrust of the electromagnetic release is only about 0.5N. The electronic release utilizes the output voltage of a secondary circuit of a mutual inductor to excite the residual current release after being amplified by an electronic circuit, the thrust of a top rod frame of the electronic release is about 1.5N, and the thrust of the electronic release is about 3 times that of the traditional electromagnetic release, so that the traditional electromagnetic release cannot meet the requirement of the traditional domestic circuit breaker on the release thrust.
