A device for pressurizing and replenishing oil outside a power capacitor tank

Abstract

The invention discloses a pressurization and oil supplement device outside a power capacitor tank. The pressurization and oil supplement device comprises a base, wherein a fixed block is arranged at an upper end of the base, a groove is formed in an upper end of the fixed block, a device cavity is formed in an inner wall opposite to the groove, multiple groups of arc blocks are arranged on an inner wall opposite to the device cavity and are opposite in positions, limitation grooves are formed in side walls of the arc blocks, a push rod is arranged on a side wall of the fixed block in a penetrating way, a limitation block is arranged on the push rod and is matched with the limitation grooves, a handle is arranged at one end of the push rod, a prop block is rotatably connected with one end,far away from the handle, of the push rod and is fixedly connected with an inner wall of the groove via a buffer device, a round cavity is formed in an internal bottom part of the groove, and a movable rod is arranged in the round cavity and is fixedly connected to an internal bottom part of the round cavity via a spring. The pressurization and oil supplement device is reasonable in structural design and simple to operate, the clamping of a capacitor is facilitated, oil injection is convenient, and the oil injection efficiency of the capacitor is greatly improved.

Description

technical field [0001] The invention relates to the technical field of special manufacturing equipment for capacitors, in particular to a pressure oil supply device outside a power capacitor tank. Background technique [0002] During the production process of power capacitors, impregnation should be carried out outside the tank, the purpose of which is to maximize the penetration of insulating oil into the gaps of the internal components of power capacitors. At the same time, due to its own characteristics of thermal expansion and cold contraction, it is necessary to prolong the natural immersion time to reduce the internal temperature of the product, so as to ensure that the insulating oil inside the product is sufficient. [0003] The existing special manufacturing equipment for capacitors is too cumbersome to clamp, and at the same time, the clamping force is not easy to control, and it is easy to damage the capacitor. Therefore, we have introduced a kind of pressure oil ...
