Description

Technical Field

[0001] The utility model relates to the technical field of transformer substations, in particular to a prefabricated cabin-type switchgear with a detachable busbar bridge hanger. Background Art

[0002] The prefabricated cabin switchgear is manufactured and processed into a prefabricated cabin, and the switch cabinet is integrated with the prefabricated cabin. The installation of the switch cabinet and the connection between the cabinets are completed in the factory. The prefabricated cabin and the switch cabinet are then transported to the substation site together. After the cabin is in place on site, it can be powered on. This reduces on-site civil construction time, saves construction period, reduces safety hazards, and is green and environmentally friendly.

[0003] Existing busbar bridge hangers for prefabricated cabin switchgear are typically welded to the cabin roof. This method is cumbersome to install, and sparks and slag from welding can easily damage the insulation panels and anti-static flooring within the cabin, posing a fire hazard. Furthermore, once the hanger is fixed, it cannot be adjusted later, making assembly and disassembly difficult. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a detachable busbar bridge hanger for a prefabricated cabin-type substation, which is easy to install and use, can prevent open flame operations, and eliminate fire hazards.

[0005] The utility model is realized through the following technical scheme: a prefabricated cabin-type switchgear with a detachable busbar bridge hanger, comprising a cabin body, a ring beam frame is provided on the top of the cabin body, a supporting connecting beam is provided on the ring beam frame, a screw connecting beam is provided on the supporting connecting beam, and the hanger comprises a supporting crossarm and at least two screws, the upper end of the screw is passed through the screw connecting hole and connected to the supporting connecting beam through an adjusting nut, the lower end of the screw is connected to the supporting crossarm, and the busbar bridge is fixed on the supporting crossarm.

[0006] The supporting connecting beams of the hanger and the ring beam frame described in this solution are connected by adjusting nuts, which does not require welding, eliminates fire hazards, is easy to disassemble and assemble, and facilitates later position adjustment, making it more convenient to use.

[0007] As an optimization, the adjustment nut includes an upper limit nut and a lower limit nut, which are respectively located on the upper and lower sides of the supporting beam. This optimization solution uses two nuts to limit the screw rod, making the hanger more stable after installation and convenient for adjusting the hanger height.

[0008] As an optimization, the supporting connecting beam is a C-shaped steel. This optimized C-shaped steel structure is lighter and convenient for opening.

[0009] As an optimization, the top of the ring beam supports the cabin roof, and the bottom of the ring beam is connected to the ceiling, which has a through hole for the screw to pass through. This optimization uses the ring beam to support the cabin roof, which is easy to install, and the ring beam is hidden by the ceiling, which is more beautiful.

[0010] As an optimization, the ring beam frame is a rectangular frame, and multiple supporting beams are fixedly connected to the ring beam frame, and the multiple supporting beams are arranged along the length of the ring beam frame. This optimization supports the connecting beam and the ring beam frame as one piece, which can be prefabricated in advance to avoid later welding.

[0011] As an optimization, a plurality of reinforcing sub-beams are arranged along the length direction of the ring beam frame, and the ends of the reinforcing sub-beams are fixedly connected to the ring beam frame. This optimization improves the structural strength of the ring beam frame.

[0012] As an optimization, a plurality of hatch cover connection holes are opened on the top of the ring beam frame along the circumferential direction. This optimization facilitates the bolt connection between the ring beam frame and the hatch cover.

[0013] As an optimization, the side wall of the ring beam frame is provided with a plurality of assembling and connecting holes along the circumferential direction. This optimization facilitates the assembly, connection and fixation of adjacent ring beam frames.

[0014] The beneficial effects of the utility model are as follows: the hanger and the supporting beam are detachably connected and fixed by adjusting nuts, and the hanger installation does not require welding, which can prevent open flame operations and eliminate fire hazards. It is easy to disassemble and assemble, and is convenient for later position and height adjustment, making it more convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS
