Problems solved by technology

If there is flammable and explosive dust or gas, humid air or liquid, there will be hidden dangers such as leakage, short circuit, etc. If it is difficult to fully seal the external control circuit of the electrical appliance, the cost will be high
[0003] After searching, a hybrid AC contactor passive switch drive controller based on an optocoupler, its patent number 200910306608.6, is disclosed on the Internet. The isolation of the three-phase bidirectional thyristor is uniformly provided with the switching signal controlled by the optocoupler, and the direct drive of the hybrid AC contactor based on the isolation of the optocoupler and the switch control is realized, and the arc-free connection and separation is realized, but its substantive shortcomings are : The control circuit is still an electronic control system, connected by wires, but a first-level optocoupler isolation and direct connection control of the switch are added. This control circuit can not solve the safety hazards such as leakage and short circuit.

Description

technical field [0001] The invention relates to an electrical control device, in particular to a light control contactor. Background technique [0002] In the existing electrical control field, a contactor is a widely used electrical control device, usually used in occasions where the power supply circuit of the control object needs to be frequently connected or disconnected. Its control objects are usually electric loads such as motors, resistors, transformers, frequency converters or other working machines and various power units, such as attached Figure 5 and Figure 6 As shown, this contactor is mainly composed of an insulating shell and an electromagnetic system inside the insulating shell, a contact system, a spring, and terminals A-H. The electromagnetic system includes an electromagnetic coil 2, a moving iron core 4 and a static iron core 1. Generally, those with larger capacity are equipped with an arc extinguishing device in the insulating shell to quickly cut of...
