High-voltage power capacitor

The utility model discloses a high-voltage power capacitor, and relates to the technical field of power capacitors, the capacitor can be fixedly mounted at a required position through a mounting block, an external lead and a wiring terminal are connected through a wiring hole for use, and vibration generated by a capacitor body during working can be effectively relieved through a buffer device. According to the high-voltage power capacitor, the vibration of the capacitor body can be reduced, noise generated by vibration can be further reduced, electronic components in the capacitor body can be protected, heat generated when the high-voltage power capacitor works can be dissipated by forming a plurality of air holes in the two side walls of the protection shell, external rainwater can be effectively blocked by arranging waterproof air-permeable films at the air holes, and the service life of the high-voltage power capacitor can be prolonged. Rainwater is difficult to enter the protective shell through the air
