The present invention provides a self-healing capacitor with safety protection means, which comprises: a casing which is made of flame retardant plastic or metal; a capacitor core is encapsulated in the casing; a first electrical contact and a second electrical contact are provided on the capacitor core, the second electrical contact is connected to a current fuse which is connected to a second leading-out, and the first electrical contact is connected to a first leading-out. In the present invention, a current fuse matches the value of the capacity current accurately, it can make the current fuse keep operating normally when in test and in normal operation. At the moment that the capacitor core comes up with severe self-healing discharge or thermal breakdown in the operation, the current fuse will burn out immediately and break the power supply circuit of the capacitor core. Therefore, it can avoid explosions and accidents arising. |
