Detailed ways

The present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

As shown in Figures 1 and 2, a high-voltage capacitor cabinet with explosion-proof function on the front panel. The capacitor cabinet body is a frame structure, and the upper, lower, left, right, and back sides are covered with iron plates. The cabinet is provided with a drive for opening or closing the circuit breaker. The cabinet is also provided with lighting and electromagnetic locks; the front panel includes a lower cabinet door 1, an upper cabinet door 2 and a beam 3; the beam 3 is a part of the frame structure, and the two ends of the beam 3 are fastened to the left and right On both sides of the frame; the beam 3 is installed with a locking structure 4, a lighting control switch 5 and an electromagnetic lock switch 6; the back of the beam 3 is provided with a plurality of wire clips, and a plurality of wires are fixed in the wire clips. The upper part forms an explosion-proof window 7 structure, the explosion-proof window 7 is a mesh hollow structure formed on the door panel of the lower cabinet door 1 , and the hollow part and the door panel of the lower cabinet door 1 are an integrated structure.

A rotating shaft through hole is formed in the middle of the locking structure 4, a main drive shaft is arranged in the transmission mechanism in the cabinet, and one end of the main drive shaft is exposed in the through hole of the rotating shaft; the through hole of the rotating shaft is covered with a closed hinge; The shells of structure 4 are locked to each other.
