Embodiment 1

[0048] As shown in the figure, an openable busbar room includes a busbar room skeleton 1, three wall bushings 2, three main busbars 3, three branch busbars 4, three contact boxes 5, interlocking Mechanism 6, busbar lap joint mechanism 7.

[0049] The three wall-through bushings 2 are arranged in the busbar room skeleton 1 and arranged in a horizontal pattern, and the three main busbars 3 pass through the busbar room skeleton 1 and then respectively pass through the three wall-through bushings 2 , one end of the three branch busbars 4 is connected to the contact box 5 , and the other end is respectively connected to the three main busbars 3 through the busbar overlapping mechanism 7 .

[0050] Such as Figure 1-4 As shown, the busbar room framework 1 includes a fixed frame 11 and a movable frame 12, and the wall-through bushing 2 includes a static bushing 21 and a moving bushing 22, both of which are split structures.

[0051]The static sleeve 21 is fixedly installed on the f...

Embodiment 2

[0088] Such as Figure 21-22 , a switchgear, comprising a switch body 10 and an openable busbar chamber arranged on the switch body 10 .

[0089] The structure of the openable busbar chamber is consistent with the first embodiment.

[0090] The fixed frame 11 of the openable busbar compartment is integrally formed with the switch body 10, which is an extension of the frame of the switch body.

Embodiment 3

[0092] Such as Figure 23 As shown, a switchgear includes a switch body 10 and an openable busbar chamber arranged on the switch body 10 .

[0093] Its structure and principle are basically the same as those of Embodiment 2, except that the three wall bushings 2 and the main busbars 3 are arranged in a vertical line.

[0094] Correspondingly, the three groups of wall-piercing bushings 2 all adopt a horizontal division method in which vertical static bushings and vertical dynamic bushings cooperate.

Abstract

Disclosed are a switchgear and an openable busbar room. The switchgear and the openable busbar room mainly solve the problem of difficult installation of busbars in a conventional busbar room. The openable busbar room is characterized in that a skeleton of the busbar room is of a split structure and includes a fixing frame and a movable frame, the movable frame is provided with a first position opened separately from the fixing frame and a second position closed together with the fixing frame, an interlocking mechanism is arranged between the fixing frame and the movable frame, three wall bushings are arranged, each wall bushing is of a split structure and includes a static bushing and a moving bushing, the static bushings are fixedly mounted on the fixing frame, and the moving bushings are correspondingly mounted on the movable frame. The advantages of the openable busbar room are that when the busbars are installed, the skeleton of the busbar room and the wall bushings can be opened,wen the installation is completed, the skeleton of the busbar room and the wall bushings are closed, five-protection interlocking requirements of electrical equipment can be achieved through the interlocking mechanism, which makes the installation of the busbars very simple, and the split type wall bushings are used instead of closed type wall bushings, which can effectively solve an eddy currentproblem.

Description

technical field [0001] The invention relates to the field of power transmission and distribution, in particular to a switchgear and an openable busbar room. Background technique [0002] The horizontal main busbar of the switchgear in the field of power transmission and distribution is widely used in distribution station equipment as the main carrier for the switchgear to transmit and distribute power. [0003] Since the main busbar carries a relatively large current, when it passes through the adjacent switchgear, a wall bushing must be installed. [0004] The busbar compartments of existing switchgears are all closed, and the wall bushings are also of closed-loop design, which leads to the fact that after the on-site switchgears are combined, the main busbar can only pass through the wall between the busbar compartments of the corresponding switchgears from the side. The bushing is then connected with the branch busbars of each switchgear through screws. In this way, on-...
