Electrolytic capacitor working electrolyte leakage-proof device

Abstract

The invention discloses an electrolytic capacitor working electrolyte leakage-proof device, and relates to the technical field of capacitors. The electrolytic capacitor working electrolyte leakage-proof device comprises a capacitor body, an aluminum shell and an electrode tube. The bottom of the electrode tube is in plug-in connection with the top of the aluminum shell, the outer wall of the electrode tube penetrates through the inner wall of the capacitor body, and the aluminum shell is arranged in the capacitor body. The outer wall of the aluminum shell is in lap joint with an electrolyte adsorption device, the bottom of the aluminum shell is fixedly connected with a heat conduction base, and the electrolyte adsorption device comprises a built-in frame and a liquid transition foil. Through cooperation of the heat conduction plate and the heat conduction seat, the temperature of the surface of the aluminum shell can be reduced, electrolyte leakage caused by over-high local temperature of the surface of the aluminum shell is prevented, and the temperature of the surface of the aluminum shell can be homogenized, so that the possibility that the electrolyte leaks outwards due to over-high external temperature is firstly avoided; the problem that leakage of the electrolyte is influenced by external factors is solved.

Description

technical field [0001] The invention relates to the technical field of capacitors, in particular to an anti-leakage device for working electrolyte of an electrolytic capacitor. Background technique [0002] A capacitor is an element that stores electricity and energy. One conductor is surrounded by another conductor, or the electric field lines emitted by one conductor are all terminated in another conductor. The device can act as a buffer protection for the capacitor. There are following problems at prior art: [0003] 1. The reason for the leakage of the electrolyte in the capacitor is generally that the internal pressure voltage is too large, which leads to a certain part of the capacitor's internal temperature being too high, resulting in damage to the aluminum shell that wraps the yin and yang foils, resulting in electrolysis. liquid leakage; [0004] 2. When the electrolyte leaks, if the electrolyte cannot be adsorbed, the electrolyte will leak to the surface of the...

Problems solved by technology

[0005] The invention provides an anti-leakage device for the working electrolyte of an electrolytic capacitor. One of the purposes is to have the ability to cool down the temperature inside the capacitor, ensure the uniform surface temperature of the capacitor, and solve the problem of electrolysis caused by excessive local temperature on the surface of the capacitor. The problem of liquid leakage; another purpose is to solve the problem that the electrolyte cannot be adsorbed and stored when it leaks, so as to avoid the effect of flowing to the outside of the capacitor when the electrolyte leaks
