Abstract

The invention relates to the technical field of vacuum arc-extinguishing chambers, and particularly discloses an improved vacuum arc-extinguishing chamber, which comprises an insulating shell, a static contact and a movable moving contact. A corrugated pipe and a shielding cylinder are positioned in the insulating shell, the corrugated pipe sleeves the outer side of the moving contact, and a firstsolder ring is welded to seal a gap between one end of the corrugated pipe and the insulating shell; the second welding flux ring is used for welding and sealing a gap between the other end of the corrugated pipe and the moving contact; the shielding cylinder surrounds and sleeves the outer side of the first contact and the outer side of the second contact; the third solder ring is welded with the shielding cylinder and the insulating shell; the fourth solder ring is used for welding and sealing a gap between the static contact and the insulating shell. By means of the arrangement of the first solder ring, the second solder ring and the fourth solder ring, welding sealing of the first contact, the second contact and the insulating shell is achieved, and the vacuum sealing performance of the first contact and the second contact is fully guaranteed. By means of the arrangement of the third solder ring, stable connection between the shielding cylinder and the insulating shell is achieved, and the electromagnetic shielding performance of the first contact and the second contact is fully guaranteed.

Description

technical field [0001] The invention relates to the technical field of vacuum interrupters, and in particular discloses an improved vacuum interrupter. Background technique [0002] Vacuum switch tube, also known as vacuum interrupter, is the core component of 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 through the excellent insulation of the vacuum inside the tube, so as to avoid accidents and The occurrence of accidents is mainly used in the power transmission and distribution control system of electric power, and also used in power distribution systems such as metallurgy, mining, petroleum, chemical industry, railway, broadcasting, communication, and industrial high-frequency heating. It has the characteristics of energy saving, material saving, fire prevention, explosion protection, small size, long life, low maintenance cost, reliable operation and ...
