Contact head heat dissipation system with good heat dissipation effect

Abstract

The invention discloses a contact head heat dissipation system with a good heat dissipation effect. The contact head heat dissipation system comprises a shell, a static contact head, a dynamic contacthead and a water cooling circulation system; the static contact head is fixedly mounted inside the shell through a static conductive rod, and one end, far away from the static contact head, of the static conductive rod penetrates through the top of the shell to be in contact with a first heat dissipation fin; the dynamic contact head is arranged inside the shell through a dynamic conductive rod and is positioned under the static contact head; a corrugated pipe is arranged between the dynamic contact head and the bottom of the shell on the dynamic conductive rod; the water cooling circulationsystem comprises a heat conducting water pipe, a water tank and a micro water pump, the heat conducting water pipe is wound on the outer wall of the shell, and the high end of the heat conducting water pipe is communicated with the top of the water tank arranged on one side of the shell through a hose. The contact head heat dissipation system with the good heat dissipation effect has the benefitsthat through the design of a water cooling device, heat transferred from the shell is effectively dissipated, so that the heat dissipation efficiency is improved, and the service lives of the contactheads are prolonged; the practicability is strong, and the popularization and the use are strong.

Description

technical field [0001] The invention relates to the technical field of contact heat dissipation in a vacuum interrupter, in particular to a contact heat dissipation system with good heat dissipation effect. 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 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, l...
