Abstract
The utility model relates to a wiring insulator of a transformer low-voltage switchgear, which consists of a main insulating board and two side insulating boards, wherein the upper parts of the two side insulating boards are outwards bent and opened to form wing boards, the lower parts of the two side insulating boards are inwards bent to form base boards, the base boards are perpendicular to the side insulating boards, insulating magnet strips are adhered on the lower surfaces of the based boards and used for being adsorbed at the bottom of a wire bridge rack, the main insulating board and the two side insulating boards are in U-shaped connection, and the distance between the lower end of the main insulating board and the insulating magnet strips is identical with the height of the wire bridge rack. A width regulating board is arranged between the side insulating boards and the main insulating board and is movably connected with the main insulating board by a pin shaft and a pin shaft hole. The wiring insulator separates a working position from an electrified position so as to thoroughly avoid electric shock accidents and alternating current short circuit caused by the falling of tools. For the wiring isolator, the structure is simple, the use is convenient, the operation efficiency is improved, and the operation cost is lowered.
Description
Technical field
The utility model relates to a kind of transformer low voltage switch cubicle wiring seal.
Background technology
At present, 220kV transformer station part low-pressure chamber exchanges 380 volts of power distribution cabinets and adopts drawer-type structure mostly, when installing in the early stage, generally be when exchanging 380 volts of power supplys in the drawing design access station, do not finish under the electriferous state, As time goes on, to constantly increase new equipment in the transformer station, just need to insert new 380 volts of power supplys of interchange, the communication switch power supply newly-increased as communication speciality, need to insert two-way and exchange 380 volts of power supplys, there is following problem in cabinet during my drawer type low tension switch wiring at work: 1, wiring position is narrow and small during lead-in cable, and distance is near between the binding post.The cable joint position of 2, using is all charged, and work this moment on empty position, touches easily when newly inserting cable connection by mistake, very dangerous, simultaneously in the wiring process, as careless employed instrument landing, also cause ac short circuit easily, harm equipment normally moves.So there is unsafe factor in a job, has the accident potential that threatens the person or device security.
The utility model content
The purpose of this utility model provides a kind of wiring operation can carried out safely on the service position, guarantee the safety of workmen and equipment, the transformer low voltage switch cubicle wiring seal of increasing work efficiency.
For achieving the above object, the technical solution adopted in the utility model is: a kind of transformer low voltage switch cubicle wiring seal, form by main insulation plate and 2 side insulation boards, the top of 2 side insulation boards outside bending flare up flap plate, the bottom of 2 side insulation boards inwardly is bent into sole, sole is vertical with the side insulation board, the lower face of sole is bonded with the insulation magnetic stripe that is used to adsorb online crane span structure bottom, the main insulation plate is the U type with 2 side insulation boards and is connected, and the lower end of main insulation plate is consistent with the height of line crane span structure with the distance that insulate between the magnetic stripe.
Above-mentioned transformer low voltage switch cubicle wiring seal is provided with width adjustment plates between described side insulation board and the main insulation plate, and width adjustment plates and main insulation plate flexibly connect by bearing pin, pin shaft hole.
Owing to adopt technique scheme, the beneficial effects of the utility model are: the utility model separates working position and charged position, the staff can relieved bold work in switch cubicle, saves the operating time, thoroughly avoids the ac short circuit that electric shock accidents takes place and the instrument landing causes.Can be applicable to the line crane span structure that the wiring position space is not of uniform size flexibly according to the spacing between each transformer station's low-voltage cabinet binding post position width degree adjustment side insulation board simultaneously.The utility model is simple in structure, and is easy to use, improved operating efficiency, reduced operating cost.
Other advantages of the present utility model, target and feature will be set forth to a certain extent in the following description, and to a certain extent, based on being conspicuous to those skilled in the art, perhaps can from practice of the present utility model, obtain instruction to investigating hereinafter.Target of the present utility model and other advantages can be passed through following specification, claims, and the specifically noted structure realizes and obtains in the accompanying drawing.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
