Description

Transformer station's double-bus balance insulating ladder of sealing up a door
Technical field
The utility model relates to a kind of insulating ladder, and the transformer station's double-bus balance particularly using in the transformer station double-bus live line working insulating ladder of sealing up a door, belongs to electric power conveying technology field.
Background technology
In power system operation and maintenance live line working process, often need operating personnel to enter the charged assembling and disassembling connecting line of highfield, after charged dismounting connecting line, maintainer, to maintenances that can have a power failure such as isolating switch, rotary switch and vertical type switches, does not need operations staff to lead interval and load rejection.If but can not charged dismounting connecting line, need to lead interval and load rejection, operations staff need to operate more than 200 time at every turn so, is easy to cause by mistake and draws by mistake and close, and can cause large-area power-cuts, has potential safety hazard and causes economic loss.And at present, the charged dismounting connecting line of operating personnel need hang insulating ladder and keep double-bus level in double-bus, in operating process, insulating ladder is easily deviate from from bus, and the person to operation field operating personnel and field apparatus all exist potential safety hazard.
Utility model content
The utility model is for above-mentioned problems of the prior art, and a kind of transformer station double-bus balance insulating ladder of sealing up a door is provided, and solved insulating ladder in prior art and easily from bus, deviate from, and has the problem of potential safety hazard.
The technical solution of the utility model is as follows.
Comprise insulating ladder body, the upper end of body arranges insulation board, and the top of insulation board arranges crossbeam, and the two ends of crossbeam are connected with one end of support bar respectively, and the other end of two support bars fastens with crossbeam and forms tripod; The top of tripod is provided with aluminium alloy plate, and the below of aluminium alloy plate is provided with bolt, and the both sides that the lower surface of aluminium alloy plate is positioned at bolt are provided with groove; The inner surface of nut is sleeved on bolt, and the outer surface of nut is fixedly connected on the fastening place, top of support bar, on nut outer surface, welds whippletree.
Described insulation board is right angle U-shaped.
Described crossbeam two ends are fixed by punching bolt and insulation board.
Described bolt top is embedded in aluminium alloy plate inside, and aluminium alloy plate and bolt are by fixing screw-tightened.
Described bolt passes from the top of aluminium alloy plate.
Described groove is circular arc, and circular arc internal diameter and bus external diameter match.
Spacing between spacing and bus between described groove matches.
Described whippletree length is greater than the spacing between groove.
The utlity model has following advantage:
Ensure that transformer station's live line working is convenient, fast, safety, in double-bus, hanging insulating ladder keeps double-bus level, insulating ladder to be automatically locked after hanging, can prevent that insulating ladder from deviating from from bus, improve field work safe, ensure the person and device security.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure, 1, aluminium alloy plate, 2, set bolt, 3, groove, 4, bolt, 5, nut, 6, whippletree, 7, support bar, 8, crossbeam, 9, punching bolt, 10, insulation board, 11, body.
Embodiment
Referring to accompanying drawing, in conjunction with specific embodiments, describe concrete structure of the present utility model in detail.
embodiment 1
As shown in Figure 1, comprise insulating ladder body 11, the upper end of body arranges right angle U-shaped insulation board 10, and the top of insulation board arranges crossbeam 8, and crossbeam two ends are fixed by punching bolt 9 and insulation board; The two ends of crossbeam are connected with one end of support bar 7 respectively, and the other end of two support bars fastens with crossbeam and forms tripod; The top of tripod is provided with aluminium alloy plate 1, and the below of aluminium alloy plate is provided with bolt 4, and bolt top is embedded in aluminium alloy plate inside, and aluminium alloy plate and bolt are fastening by fixing spiral 2; The both sides that the lower surface of aluminium alloy plate is positioned at bolt are provided with circular groove 3, and circular groove internal diameter and bus external diameter match, and the spacing between spacing and bus between circular groove matches; The inner surface of nut 5 is sleeved on bolt, and the outer surface of nut is fixedly connected on the fastening place, top of support bar, welds whippletree 6 on nut outer surface, and whippletree length is greater than the spacing between groove.
embodiment 2
Described bolt passes from the top of aluminium alloy plate, and other structure is with embodiment 1.
Use before the utility model, between groove and whippletree in open mode.When use, push down insulating ladder body bottom by ground handling personnel, operating personnel lifts insulating ladder body top in addition, vertical insulating ladder straight, then lift insulating ladder and aim at the insertion of double-bus centre position, half-twist, circular groove is aimed at bus, hang in double-bus, at this moment the rotating insulated ladder of ground electrician makes to move on the nut on whippletree, until whippletree seals circular groove, locked bus stops the rotation, adjust insulating ladder angle, comfortable while making the upper and lower insulating ladder of live line working personnel, person distance to the ground, combined distance, phase spacing, range estimation reaches requirement, can carry out operation.
The above is specific embodiment of the utility model and the know-why used, and any equivalent transformation based on technical solutions of the utility model basis, within all belonging to protection range of the present utility model.
