Problems solved by technology

Due to damage to the insulation of switching appliances, operator errors, failure to ensure safety, lack of awareness of household electricity safety, failure to ensure that hands are dry when using switching appliances, etc., may lead to current leakage and electric shock accidents.
At present, despite the continuous improvement of equipment insulation and the continuous improvement of safety performance, it is still impossible to fundamentally solve the danger of operators being electrocuted by high voltage

Abstract

The invention relates to a wireless energy-taking operating mechanism of a contact switch electric appliance. Including high-frequency power supply, optimization board, transmitting coil, magnetizer, receiving coil, connecting rod mechanism, arc extinguishing chamber, moving contact, static contact, driving coil, capacitor; among them, moving contact and wireless energy-taking operating mechanism The mechanism is connected with each other and acts synchronously; the mechanism completes the transmission of wireless energy through the transmitting coil and the receiving coil to control the closing of the switch. The electromagnetic field is optimized. The invention can realize multiple isolations between the power supply part and the power part, the power part and the action part, and the action part and the electrical connection part in the operating mechanism, which reduces the possibility and danger of electric shock for personnel, and makes the contact switch electrical appliances more convenient and easier. Safety. This mechanism is especially suitable for places with high insulation performance requirements, limited wiring space, and special electrical isolation requirements.
