A semi-closed capacitor overheating prevention device with dust removal function

Abstract

The invention relates to the field related to capacitors, and discloses a semi-closed capacitor overheating device with a dust removal function, comprising a dustproof box body, the dustproof box body is provided with a dustproof box inner cavity with an opening to the left, and the dustproof box The lower side of the inner cavity is connected with a support plate cavity, and the lower side of the inner cavity of the dustproof box is connected with an annular cavity of the ring gear seat on the left side of the support plate cavity. The end surface of the end face ring gear seat is fixedly connected with the end face ring gear, and a plurality of annular cavity springs are fixedly connected between the lower end surface of the end face ring gear seat and the lower end wall of the ring cavity of the ring gear seat. When the temperature of the inner cavity of the dustproof box exceeds a certain value , the large turntable drives the two working capacitors to rotate for half a circle to realize the replacement of the working capacitors, thereby preventing the original working capacitors from being deformed due to overheating. When the capacitors are replaced, the cleaning sliding plate is replaced at the same time to drive the cleaning brush to move downward or upward, so as to realize the work. Cleaning of capacitor surfaces.

Description

technical field [0001] The invention relates to the related field of capacitors, in particular to a semi-closed capacitor overheating prevention device with dust removal function. Background technique [0002] The power of current large-capacity capacitors is usually high, and it is easy to deform due to high temperature during long-term work, which has certain safety hazards. At the same time, the surface of the capacitor is very easy to attract a large amount of dust due to static electricity, which seriously affects For the heat dissipation of the capacitor, if a dust cover is added to the capacitor, the effect of air cooling and heat dissipation will be reduced. On the other hand, the self-healing capacitor can prevent the work of all capacitors from stopping due to overheating, but the capacity of the self-healing capacitor will decrease. Decreases with use, affecting the working performance of the corresponding device. Contents of the invention [0003] The object o...
