Abstract
The present invention relates to a transformer substation double bus balance enclosure insulating ladder. The transformer substation double bus balance enclosure insulating ladder comprises an insulating ladder body, the upper end of the body is equipped with an insulating plate, and the upper part of the insulating plate is equipped with a crossbeam. The two ends of the crossbeam are connected with one ends of the supporting rods respectively, and the other ends of the two supporting rods are buckled with the crossbeam to form a triangular rack. An aluminum alloy plate is arranged above the triangular rack, a bolt is arranged below the aluminum alloy plate, and the lower surface of the aluminum alloy plate at the two sides of the bolt is equipped with grooves. The inner surface of a nut sleeves on the bolt, the outer surface of the nut is fixedly connected with the buckled top ends of the supporting rods, and a transverse lever is welded on the outer surface of the nut. The transformer substation double bus balance enclosure insulating ladder of the present invention guarantees that the transformer substation live-line work is convenient, rapid and safe. The insulating ladder is hung on double buses to keep the double buses horizontal and is locked automatically after being hung, so that the insulating ladder can be prevented from falling off from the buses, the on-site work safety is improved, and the personal and equipment safety is guaranteed.
Description
Technical field
The present invention relates to a kind of insulating ladder, 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.
Summary of the invention
The present invention is directed to above-mentioned problems of the prior art, a kind of transformer station double-bus balance insulating ladder of sealing up a door is provided, solved insulating ladder in prior art and easily from bus, deviate from, have the problem of potential safety hazard.
Technical scheme of the present invention 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.
Tool of the present invention has the following advantages:
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.
