detailed description

As shown in Figures 1-5, the utility model includes a single element 1, a copper bar clip 2, a bent copper bar 3, a bolt hole 4, a phase mark 5 and a through hole 6.

There are four unit elements 1, and the unit element 1 is formed by buckling the left protective cover 11 and the right protective cover 12; , the through hole 6 of the right protective cover 12; after the four unit elements 1 are arranged in sequence, they are fastened into a whole by the long bolts inserted into the through hole 6; four interlayers are formed after the four unit elements are composed, and each interlayer is provided with A bent copper bar 3 is provided with a copper bar clip 2 in the interlayer corresponding to the bent copper bar 3 . The shape of the bent copper bars in each unit is different, and the positions placed in the unit are different;

A bolt hole 4 is provided directly above the unit element 1 , and the outside of the bolt hole 4 is a phase indicator position 5 .

Each unit element (each phase) of the utility model is an independent unit, and the bent copper row can be stuck in any one of the four outlets. When installing, the bent copper row 3 and the copper row clamp in the four outlets The stacked bus bar copper bars 8 are inserted between the sheets 2. When in use, one end of the bent copper bar 3 is fixed on the incoming or outgoing end of the circuit breaker, and the other end is inserted into the stacked installed busbar copper bar 8, and the busbar copper bar 8 is located between the bent copper bar 3 and the copper bar clip 2 , Tighten the screw 13 in the unit unit, the copper bar clip 2 presses the busbar copper bar 8 and the bent copper bar 3, so as to realize the reliable connection between the bus bar copper bar and the unit unit. When the circuit breaker needs to be replaced, it is only necessary to loosen the mounting screw on the circuit breaker bracket 10 and the screw 13 in the unit unit to be easily removed; the installation is easy, and the maintenance and replacement are convenient.

Each phase of the utility model is an independent unit, and can be combined and used at will according to the phase requirements of the branch lines. There is no need to use separate protection measures such as protective covers, and the conductive parts of complex connections are not exposed, avoiding electric shock accidents, short circuits and fire accidents.
