Problems solved by technology

[0003] At present, the electromagnetic repulsion operating mechanism generally uses a full-bridge rectification method to charge the energy storage capacitor, and the trigger relies on a fully-controlled semiconductor device (such as IGBT). This method has defects such as low pulse current peak value and high price.

Abstract

The invention discloses energy storage and triggering equipment for an electromagnetic repulsion operating mechanism and a control method. The equipment comprises a voltage regulator, an isolation transformer, an opening charging resistor, an opening charging diode, an opening energy storage capacitor, an opening thyristor, an opening free-wheeling diode, a closing charging resistor, a closing charging diode, a closing energy storage capacitor, a closing thyristor and a closing free-wheeling diode. With adoption of the scheme, by means of the diode half-wave rectification charging and thyristor triggering discharging method, charging of energy storage capacitors can be guaranteed, zero-crossing natural switch off of thyristor current can be realized, and a trigger switch doesn't require an expensive full-controlled power semiconductor device with lower current peak endurance capacity.

Description

technical field [0001] The invention belongs to the field of breaking electrical appliances, and in particular relates to an energy storage and trigger device of an electromagnetic repulsion operating mechanism and a control method. Background technique [0002] The principle of the action of the electromagnetic repulsion operating mechanism is that the pre-charged energy storage capacitor discharges to the closing or closing excitation coil, and an eddy current is induced on the repulsion disk. The magnetic field generated by the eddy current is opposite to the direction of the magnetic field generated by the discharge current in the coil, generating electromagnetic repulsion. Pushing the repulsion plate drives the movement of the connecting rod to realize opening and closing. Therefore, the energy storage and triggering equipment of the electromagnetic repulsion operating mechanism are the key to its energy storage and control. [0003] At present, the electromagnetic rep...
