Description

Technical Field

[0001] The utility model relates to the technical field of vacuum arc extinguishing chamber production equipment, in particular to a clamping groove structure for preventing vacuum arc extinguishing chamber from being processed and jittered. Background Art

[0002] The vacuum interrupter, also known as the vacuum switch tube, is the core component of the medium and high voltage power switch. Its main function is to quickly extinguish the arc and suppress the current after the medium and high voltage circuit is cut off from the power supply through the excellent insulation of the vacuum in the tube, so as to avoid accidents and unexpected events. It is mainly used in the power transmission and distribution control system, and also used in metallurgy, mining, petroleum, chemical industry, railway, broadcasting, communication, industrial high-frequency heating and other power distribution systems. It has the characteristics of energy saving, material saving, fire prevention, explosion prevention, small size, long life, low maintenance cost, reliable operation and no pollution. The vacuum interrupter is divided into the interrupter for circuit breakers and the interrupter for load switches in terms of use. The interrupter for circuit breakers is mainly used in substations and power grid facilities in the power sector, and the interrupter for load switches is mainly used for end users of the power grid.

[0003] During the production process, it needs to be assembled, vacuumed, baked and degassed, and finally cold clamped and sealed, which is a very cumbersome process. Moreover, after the assembly is completed, these semi-finished arc extinguishing chambers are generally placed in customized grooves. During the process, they may be shaken due to loose fixation, resulting in economic losses due to poor quality.

[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content
