The invention discloses a double-coil shunt release which comprises an EMC filter circuit, a rectifying circuit, a sampling circuit, a comparison circuit, a differentiating circuit, a first switch circuit, a PWM circuit, a second switch circuit, a power circuit and a double-coil shunt electromagnet, wherein the RMC filter circuit is used for bidirectionally curbing the interference signals from a power grid and an interior circuit; the double-coil shunt electromagnet comprises a powerful winding, a maintaining winding and a movable iron core. According to the double-coil shunt release, no releasing action occurs when the power grid voltage is lower than 70% of the rated voltage, the high-reliability releasing higher than 70% is ensured, the releasing state is maintained after the releasing until the power grid voltage is lower than 30%, so that the possibility of re-closure is effectively prevented. During releasing, the power of the powerful winding of the electromagnet is relatively high to realize reliable shunt releasing while keeping extremely short power-on time, and is relatively low to maintain the releasing state; by combining the two conditions, the electromagnet can be effectively prevented from being burnt by heating and long power-on time can be realized.
