Explosion-proof low-voltage power compensation capacitor with temperature output signal

Abstract

The explosion-proof low-voltage power compensation capacitor comprises an aluminum shell, a capacitor core and an insulating buckle cover, the capacitor core is fixedly installed in the aluminum shell, the insulating buckle cover is fixedly installed at the upper end of the aluminum shell, an upper fixing sleeve is arranged at the position, located on the upper portion of the capacitor core, of the inner side of the aluminum shell, and the upper fixing sleeve is fixedly installed on the outer side of the aluminum shell. A lower fixing sleeve is arranged on the inner side of the aluminum shell and located on the lower portion of the capacitor core, a wiring terminal is movably installed at the upper end of the insulation buckle cover, and the insulation buckle cover and the wiring terminal are connected through a terminal positioning sleeve. When the capacitor is damaged or the temperature reaches a corresponding critical point, the temperature sensor gives a corresponding electric signal to the outside, so that the system gives an action in advance, unnecessary loss is avoided, the capacitor has no polarity, and the main advantages are that the frequency characteristic is good and the frequency response is wide. And meanwhile, the cable has the advantages of small dielectric loss, high insulation resistance, stable performance, impact current resistance, high overload capacity and excellent self-healing performance.
