Abstract

The utility model relates to a switchgear bus connecting device which is composed of a left box, a right box, a transitional box, a transitional bus, insulator installing beams and bus isolating sleeves. The left and right boxes are respectively fixed to the tops of left and right switchgears, the left box is communicated with the right box via the transitional box, one end of the transitional bus is connected with a bus end extended out of the left switchgear in the phase sequence, the other end of the transitional bus is connected with a bus end extended out of the right switchgear in the reverse sequence, the bus isolating sleeves are respectively arranged between adjacent sections of the transitional bus in parallel, and the transitional bus is fixedly connected to the inner sides of the left, right and transitional boxes via the insulator installing beams. According to the utility model, the spatial structure of the transitional bus is changed to realize reverse connection between the switchgears, the insulation effect is good, and the assembly structure of the boxes also provides great convenience for inspection and maintenance of the switchgear bus connecting device.

Description

Switch cabinet bus jockey

Technical field

The utility model relates to a kind of switch cabinet bus jockey, relates in particular to a kind of switch cabinet bus jockey.

Background technology

At present, in transformer station, the bus bridge boxes that use are electrically connected switch cubicle more, and the bus wire phase sequence of switch cubicle is generally A-B-C, and still, due to the restriction in place, most switch cubicle can be many rows and put.If two row switch cabinets are put face-to-face, when two switch cubicles of two row's least significant ends connect, just there will be bus wire phase sequence A-B-C to be connected with two switch cubicles of bus wire phase sequence C-B-A, because switch cubicle is batch production, the switch cubicle that is C-B-A for bus wire phase sequence is difficult to produce, and reequips voluntarily switch cubicle can have huge hidden danger by transformer station.In addition, the electric equipments such as switch cubicle are very strict for the requirement of insulation, so bus bridge box mostly is hermetically-sealed construction and structure is very complicated, and then while causing going wrong in bridge case, are difficult for removing maintenance difficult.

Summary of the invention

The utility model, for above-mentioned the deficiencies in the prior art, provides a kind of switch cabinet bus jockey.

Switch cabinet bus jockey of the present utility model, by left box body, right case, transition casing, transition bus, insulator mounting rail and forming every thread casing, described left box body and right case are individually fixed in the top of left-side switch cabinet and right-side switch cabinet, left box body is connected with right case by transition casing, one end of transition bus connects the bus line end stretching out in left-side switch cabinet by phase sequence, its other end connects the bus line end stretching out in right-side switch cabinet by backward, article three, between transition bus, be provided with side by side every thread casing, transition bus is by insulator mounting rail and left box body, right case is fixedly connected with the inner side of transition casing.

As further improvement of the utility model, described transition bus consists of main transition bus, horizontal transition section and vertical transition section, and the A phase transition bus connected with C phase bus with the A phase of left-side switch cabinet is directly connected the bus of left-side switch cabinet and right-side switch cabinet in two ends connected with C phase bus with right-side switch cabinet A phase, B phase transition wire by two sections of vertical transition sections respectively with horizontal transition section successively with C phase transition bus.

As further improvement of the utility model, described left box body is all connected by buckle with right case with transition casing, transition casing.

As further improvement of the utility model, described left box body and the base plate of right case are provided with bus casing.

As further improvement of the utility model, described transition bus is wrapped with insulation screen.

Switch cabinet bus jockey of the present utility model, reasonable in design, by the change to the space structure of transition bus, the backward having realized between two switch cubicles connects, and insulation effect is good, the splicing structure of its casing, brings great convenience also to whole device inspection and maintenance.
