Novel self-healing high-voltage capacitor

The utility model discloses a novel self-healing type high-voltage capacitor, which comprises a main body, a plurality of contact sheets are arranged around the main body, the contact sheets are connected with one another to form a sleeve body, the sleeve body sleeves the outer side of the main body and contacts with the outer side of the main body, the main body expands to drive the contact sheets to move towards the direction far away from the main body, and circuits are arranged in the contact sheets. The circuit is provided with contact points on the two sides of the contact pieces respectively, the contact points corresponding to the contact pieces abut against one another to form a communication circuit, connecting points are arranged at the two ends of the body, and the two ends of the communication circuit are connected with the connecting points at the two ends of the body respectively. Through the arrangement of the contact piece, circuit breaking can be carried out according to bulging caused by ma
