Conductive rod structure for vacuum arc-extinguishing chamber

Abstract

A conductive rod structure for a vacuum interrupter belongs to the technical field of electrical switches. The dynamic and static conductive rods are equipped with dynamic and static conductive rod cores. The dynamic and static conductive rod cores are located at the center of the dynamic and static conductive rods. One end of the dynamic and static conductive rods is connected with a dynamic and static contact. The moving contact is in flush contact, and the lower end of the steel core of the static conductive rod is in flush contact with the static contact. The mechanism of the invention is simple, by assembling the structure of the dynamic and static conductive rod cores in the center of the dynamic and static conductive rods, the mechanical strength of the dynamic conductive rod is effectively improved, and the conductive rod structure of the fast mechanical switch is prevented under the same extrusion stress Roughly deformed due to mechanical impact, good mechanical properties and low processing cost. The density of the core material of the dynamic and static conductive rods is lower than that of copper, which reduces the mass of the dynamic conductive rod, thereby reducing the closing bounce and ensuring electrical performance.

Description

technical field [0001] The invention belongs to the technical field of electric switches, and relates to a conductive rod structure of a vacuum interrupter. Background technique [0002] Vacuum interrupter, also known as vacuum switch tube, 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 cuts off the power supply through the excellent insulation performance of the vacuum inside the tube, so as to avoid nuclear accidents. The occurrence of accidents is mainly used in power transmission and distribution control systems of electric power, and also in power distribution control systems of metallurgy, mining, petroleum, chemical industry, road 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 c...
