Embodiment Construction

[0017] Such as figure 1 As shown, in the self-healing low-voltage reactive power compensation capacitor, the capacitor shell 8 is an aluminum shell with fast heat dissipation and good dense performance. There are terminals on the top, and a heat-resistant plastic terminal cover 1 on the terminals, which can effectively connect the phases Distinguish isolation and play the role of arc prevention. There are three copper pillars 2 on the terminal to ensure good contact between the capacitor and the external wiring. The copper pillars 2 are sealed with high-insulation performance and high-temperature-resistant silica gel particles 9 to ensure the sealing performance of the capacitor. Good; the copper sheet 3 is under the copper column 2, and the copper sheet and the copper column are bonded together at the moment of high current. When the capacitor is damaged by overcurrent and overvoltage for a long time, the solder joint acts as a fuse , to protect the user's device. The discha...

Abstract

The invention discloses a self-healing low-voltage reactive power compensation capacitor, which comprises a capacitor shell, a terminator, a connecting line and a metallized film. The connecting line is connected with the terminator and the metallized film; inert gas is filled in the capacitor shell; an iron middle plate is arranged on the capacitor shell; and an insulating layer is wrapped outside the metallized film. The self-healing low-voltage reactive power compensation capacitor has the advantages of small volume, light weight and high safety performance; and the self-healing low-voltage reactive power compensation capacitor with double electric protection therein can better prevent accidents such as fire hazards or oil leakage.

Description

technical field [0001] The invention relates to the technical field of electrical components, and more specifically relates to a self-healing low-voltage reactive power compensation capacitor. Background technique [0002] With the continuous progress of society, the rapid development of electrical and mechanization, the continuous increase of industrial electricity consumption, the cost of electricity consumption of enterprises has also continued to increase, and the quality of the power grid has declined significantly. In order to further improve the quality of the power grid and the safety of user electrical appliances, the cost of electricity charges For the sake of consideration, many companies began to use self-healing reactive power compensation capacitors; self-healing capacitors use a single-layer polypropylene film as the medium, and a thin layer of metal is evaporated on the surface as a conductive electrode. When an excessively high voltage is applied, the weak p...
