Description

TECHNICAL FIELD

[0001] The utility model relates to the field of power system application equipment, specifically speaking of a switchgear body for pipe bus. BACKGROUND

[0002] 35kV high voltage switch cabinet is a switch device widely used in power supply system, and the bus connected with the switch cabinet in the power system has various forms, such as rectangular bus and pipe-shaped bus. The pipe-shaped bus is widely used due to its good heat dissipation and conductivity, but because the pipe-shaped bus has a large bending radius, in the current scheme of connecting the switch cabinet and the pipe bus, the switch cabinet body is designed as a cube, the pipe bus connector is arranged outside the top of the switch cabinet, the pipe-shaped bus needs to be erected very high, and the bus in the switch cabinet also needs to be longer accordingly. Especially when the high voltage switch cabinet is installed in a prefabricated cabin, because the height of the prefabricated cabin is limited, the pipe-shaped bus cannot be inserted into the high voltage switch cabinet after being connected to the cabin from the side, and only the height of the prefabricated cabin can be increased, and the structure of the prefabricated cabin can be changed. This not only increases the material cost, but also increases the transportation cost and installation cost. At the same time, the pipe bus connector arranged outside the switch cabinet body further increases the safety hazard of the equipment. SUMMARY

[0003] To solve the above problems in the prior art, the utility model provides a switch cabinet body for pipe bus. The pipe bus is more compact and reasonable in connection with the switch cabinet.

[0004] The utility model adopts the following technical scheme to realize it:

[0005] A switch cabinet body for pipe bus, comprising a front cabinet, a rear cabinet, an instrument room, a pipe bus, a wall bushing, an insulation sealing ring, an insulation partition, a pipe bus connector, a bus in the cabinet, a rear cabinet top cover plate, a flexible connection, and a connecting bolt, wherein the pipe bus connector is installed inside the rear cabinet of the switch cabinet, the pipe bus enters the room through the wall bushing, penetrates the rear cabinet top cover plate on the rear cabinet of the switch cabinet, is inserted into the pipe bus connector, and the pipe bus connector is connected with the bus in the cabinet.

[0006] Further, an insulation partition is installed on the rear cabinet top cover plate, three holes are arranged on the insulation partition, the insulation sealing ring is arranged in the holes, and the pipe bus enters the rear cabinet of the switch cabinet body after penetrating the insulation sealing ring.

[0007] Further, a step is arranged on the outside of the rear cabinet body, and the height of the step is lower than that of the front cabinet.

[0008] Further, the pipe bus connector and the bus in the cabinet are connected by the flexible connection.

[0009] Compared with the prior art, the technical effect of the utility model lies in that the design structure is compact and reasonable, the space utilization rate is high, the safety is high, and the economic applicability is high. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0014] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0015] In order to keep the following description of the embodiments of the present invention clear and concise, the present invention omits detailed descriptions of known functions and known components.

[0016] The utility model discloses a switch cabinet for a piping busbar, which has a compact and reasonable structure and is economical and safe.

[0017] The switch cabinet is installed in a prefabricated cabin and consists of a front cabinet 1, a rear cabinet 2, an instrument room 3, a busbar 4, a wall bushing 5, an insulating seal 6, an insulating partition 7, a busbar joint 8, a busbar inside the cabinet 9, a rear cabinet top cover 10, a flexible connection 11, and connecting bolts 12.

[0018] like Figure 1 As shown, the wall bushing 5 is installed on the side plate of the prefabricated cabin. After the busbar 4 passes through the wall bushing 5 and enters the cabin, it turns 90 degrees and vertically passes through the rear cabinet top cover 10 above the rear cabinet 2 of the switch cabinet body; Figure 2 As shown, an insulating partition 7 is installed on the rear cabinet top cover 10, and insulating sealing rings 6 are installed in the three holes provided on the insulating partition 7; Figure 3 As shown, the tubular busbar 4 passes through the insulating sealing ring 6 and enters the rear cabinet 2 of the switch cabinet body, and is inserted into the corresponding position of the tubular busbar joint 8. Then, one end of the flexible connection 11 is connected to the tubular busbar joint 8 with a connecting bolt 12 and tightened, and the other end of the flexible connection 11 is connected to the busbar 9 in the cabinet with a connecting bolt 12 and tightened.

[0019] The above structure can effectively utilize space, save resource costs, and improve the safety of the switchgear.

[0020] The application has been described in detail with reference to specific embodiments in conjunction with the accompanying drawings, but the application is not limited to the above-mentioned embodiments, and various changes can be made within the knowledge of those skilled in the art without departing from the spirit of the application.
