When one of the working capacitors 2 fails, the working capacitors 2 are detached by moving the carriage 4, i.e. one circuit is disconnected from the working capacitors 2. At this time, the conductive clamping piece 91 on the second connector 62 matched with the first connector 61 on the sliding frame 4 moves to reset under the action of the reset elastic piece 92, so that the clamping part 911 is abutted against the terminal on the second connector 62, and the spare capacitor 8 can be connected into the circuit of the circuit breaking working capacitor 2, so as to ensure the power factor, save the electric energy and reduce the electricity fee consumption. At the same time, the movable end of the conductive wire 932 moves to be separated from the conductive bar 931, and at this time, the conductive clip 91 located on the side of the conductive wire 932 away from the spare capacitor 8 is disconnected from the spare capacitor 8. Therefore, even if the working capacitors 2 are detached, the standby capacitor 8 can be connected into one circuit, so that the safety of the capacitor cabinet in operation is guaranteed.
The foregoing are all preferred embodiments of the present application, and are not intended to limit the scope of the present application in any way, therefore: all equivalent changes in structure, shape and principle of this application should be covered in the protection scope of this application.
