Problems solved by technology

In this way, the entire capacitor needs to be replaced in time, but the inventor believes that for the backward areas in Africa, it is very inconvenient to replace and send for repairs, so there is an urgent need for an electrolytic capacitor that can work conveniently in a high temperature environment and has a low failure rate

Abstract

The invention relates to a high-temperature-resistant electrolytic capacitor. The high-temperature-resistant electrolytic capacitor comprises a base, a cylindrical shell matching the base to form a containing cavity, a capacitor installed in the containing cavity and an adjusting device which is arranged in the containing cavity and elastically connected with the shell and the base. An annular groove is formed in the base, the shell is embedded into the annular groove and is in threaded connection with the annular groove, and a controllable injection hole used for injecting the electrolyte into the containing cavity is formed in the top of the shell. The electrolytic capacitor has the effect of reducing the failure rate of the electrolytic capacitor in a high-temperature environment.

Description

technical field [0001] The present application relates to the field of capacitors, in particular to a high temperature resistant electrolytic capacitor. Background technique [0002] With the rapid development of the global economy, more and more Chinese-made products are being sold abroad. However, capacitors adapted to China cannot meet the high temperature environment in some foreign countries and regions in terms of high temperature resistance, especially the high temperature and harsh environment in countries such as Africa. The structure of a common electrolytic capacitor usually includes an aluminum casing, electrolytic paper rolled in the casing, and an electrolyte soaking the electrolytic paper. [0003] In the domestic environment, the room temperature is usually low, and there are usually good cooling and ventilation conditions, so the operating temperature of the electrolytic capacitor is low. However, in the backward areas of African countries, electrolytic ca...
