Abstract

The invention discloses an automatic heat dissipation capacitor capable of preventing welding heat damage, which comprises a core package, a hollow metal sleeve shell covers the core package, a plurality of annular hollow fins are arranged on the side wall of the hollow metal sleeve shell, a sealing cover is plugged in a sleeve opening of the hollow metal sleeve shell, and two mounting grooves aresymmetrically formed in the lower end of the sealing cover. Through evaporation, condensation and heat dissipation of the insulating heat conduction sleeve, the hollow wall heat conduction pipe and the refrigerant, the problem that the core cladding is damaged by heating or the service life is shortened due to overheat welding or overlong welding time of the capacitor is solved, and the problem of working heat dissipation of the capacitor is solved by attracting the magnetic piston ring through the electromagnetic box to push the refrigerant to enter the hollow metal sleeve shell.

Description

technical field [0001] The invention relates to the field of power equipment, in particular to an automatic heat dissipation capacitor for preventing welding heat damage. Background technique [0002] In the power system, capacitors are one of the indispensable power devices, and capacitors play an important role in circuits such as tuning, bypassing, coupling, and filtering. [0003] Existing capacitors are usually composed of aluminum shell, core package, rubber plug and pin rod. The pin rod is usually a metal material with good electrical conductivity, and its thermal conductivity is usually good. In the process of the circuit, the temperature of the welding gun is too high, and the welding time is too long, which leads to the conduction of high temperature into the core package through the pin rod, resulting in damage to the capacitor or shortened service life. SUMMARY OF THE INVENTION [0004] The purpose of the present invention is to solve the shortcomings of the p...
