Problems solved by technology

[0004] At present, the working breaking voltage of circuit breakers, contactors, relays, switches and other devices seen on the market in my country is only 125VDC, which is far below the working voltage of 450VDC for new energy and other mobile equipment.
In addition, the traditional electrical control devices are all made of plastic shells, which have poor arc resistance and temperature resistance. When the controlled equipment runs at full load for a long time, the conductive parts of the device will generate a lot of heat, and the high temperature will melt the plastic insulator around the conductive parts, and the conductive parts will be fixed. Short circuit caused by confusion, leading to electrical safety accidents and fires, endangering personal safety

Abstract

The invention discloses a ceramic insulating shell of a contactor, a relay, a circuit breaker and a switch, and particularly relates to a device ceramic insulating shell which has a strong arc ablation resistance, can be welded in a metallized and sealed manner, and has the functions of high dielectric strength, high breakdown voltage, high temperature resistance, acid and alkali resistance, highstrength and the like. The shell and the structure are applied to an electric control device, the on-off voltage direct current of the traditional electric control device can reach 600VDC or above, the alternating current of the traditional electric control device can reach 800VAC or above, and the safety and environmental adaptability indexes of the device can be greatly improved.

Description

technical field [0001] The patent of the present invention relates to a ceramic insulating shell, in particular to a ceramic insulating shell which has the function of strong arc ablation resistance, can be metallized and sealed and welded, and has high electric strength, high breakdown voltage, high temperature resistance, acid and alkali resistance and high Insulation ceramic housing for devices with functions such as strength. Background technique [0002] As we all know, components such as contactors, relays, circuit breakers, switches, etc. are important electrical control devices on electrical equipment. With the development of science and technology and the progress of society, China's equipment has entered the era of high-tech and intelligentization, and the power and working energy of equipment have been developed and improved at a speed of double or even dozens of times. Limited by the volume of the equipment, the only way to increase the power and working energy ...
