Leak-proof capacitor

Abstract

The invention discloses a leak-proof capacitor. The leak-proof capacitor comprises a liquid injection hole in the capacitor, a support is fixedly arranged on the inner side of the liquid injection hole, a sliding way is formed inside the support, through holes are formed in the side faces of the sliding way, springs are arranged in the sliding way, a pressing block is arranged above the springs, and the pressing block is matched with the liquid injection hole. When liquid injection is carried out through the leak-proof capacitor, liquid injection pipelines jack the pressing block open to stretch into the capacitor, liquid is injected into the two sides through the liquid injection pipelines, electrolytes are injected into the capacitor through the through holes, when the liquid injection pipelines are taken out, the springs push the pressing block to abut against the liquid injection hole to prevent the electrolytes from being sprayed out, the outer portion of the capacitor is sealed, the injected liquid leakage amount of the capacitor is reduced, and liquid injection safety is improved.

Description

technical field [0001] The invention relates to the field of capacitors, in particular to an anti-leakage capacitor. 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. In theory, 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 relying on the method of quickly sealing the liquid injection port by the workers. The electrolyte is corrosive to a certain extent, and the manual sealing of the...

[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. In theory, 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 relying on the method of quickly sealing the liquid injection port by the workers. 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
