Anti-leakage capacitor

Abstract

The invention discloses an anti-leakage capacitor which comprises a liquid injection head and a liquid injection hole on the capacitor. A polygonal cylinder is arranged at the top of the liquid injection head, and a first external thread is circumferentially arranged on the liquid injection head. A liquid injection pipe is in the liquid injection head and is provided with a channel which communicates with the outer wall of the liquid injection head from two sides. The liquid injection hole is internally provided with an internal thread and a plug. The outside of the plug is provided with a second external thread. An upper part of the plug is provided with a polygonal hole which cooperates with the polygonal cylinder. Both the first external thread and the second external thread cooperate with the internal thread. The inner side of the liquid injection hole is fixedly provided with a bracket. A sliding chute is formed in the bracket, a side face of the sliding chute is provided with a through hole, and a spring is arranged in the sliding chute. According to the capacitor, electrolyte overflow can be reduced, and the risk of the work of workers is reduced.

Description

technical field [0001] The invention relates to the field of capacitors, in particular to anti-leakage capacitors. Background technique [0002] Capacitor is a commonly used electrical device in the circuit. After the installation of the capacitor is completed, the inside of the capacitor must be filled with liquid, because if the electrolyte encounters air, it will discharge. Theoretically, it is best to refill the capacitor in a complete vacuum, but the existing technology cannot achieve it. The electrolyte should be injected until the capacitor is full. Because there is still a certain amount of air inside the capacitor before the injection, the internal pressure of the capacitor is relatively high. , when the liquid injection device leaves the liquid injection port, the electrolyte will overflow. Now it is mainly rely on the workers to quickly cover the liquid injection port. The electrolyte is corrosive to a certain extent, and the manual sealing of the workers is dange...

[0002] Capacitor is a commonly used electrical device in the circuit. After the installation of the capacitor is completed, the inside of the capacitor must be filled with liquid, because if the electrolyte encounters air, it will discharge. Theoretically, it is best to refill the capacitor in a complete vacuum, but the existing technology cannot achieve it. The electrolyte should be injected until the capacitor is full. Because there is still a certain amount of air inside the capacitor before the injection, the internal pressure of the capacitor is relatively high. , when the liquid injection device leaves the liquid injection port, the electrolyte will overflow. Now it is mainly rely on the workers to quickly cover the liquid injection port. The electrolyte is corrosive to a certain extent, and the manual sealing of the workers is dangerous. And contact with air will also affect its working performance
