Description

technical field

[0001] The invention relates to the field of electric equipment, in particular to an automatic heat dissipation capacitor for preventing welding heat damage. Background technique

[0002] In the power system, the capacitor is one of the essential power devices, and the capacitor plays an important role in tuning, bypassing, coupling, filtering and other circuits.

[0003] Existing capacitors are usually composed of an aluminum shell, a core package, a rubber plug and a lead rod. The lead rod is usually a metal material with good electrical conductivity, and its thermal conductivity is usually relatively good. Therefore, the capacitor is soldered to the During the process in the circuit, the temperature of the welding torch is too high, and the welding time is too long, so that the high temperature is transmitted to the core package through the pin rod, causing damage to the capacitor or shortening the service life.
