The present invention relates to a kind of transformer station double-bus and balance insulating ladder of sealing up a door, comprise insulating ladder body, the upper end of body arranges insulation board, and the top of insulation board arranges crossbeam, the two ends of crossbeam connect a support bar respectively, and the other end of two support bars fastens and forms tripod with crossbeam; 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, and nut outer surfaces welds whippletree.This invention ensures that transformer station's live line working is convenient, fast, safety, double-bus hangs after insulating ladder keeps double-bus level, insulating ladder to hang and be automatically locked, can prevent insulating ladder from deviating from from bus, improve field work safe, ensure that the person and device security.
Description
Technical field
The present invention relates to a kind of insulating ladder, particularly balance in transformer station's double-bus that transformer station's double-bus live line working uses insulating ladder of sealing up a door, belong to electric power conveying technology field.
Background technology
In power system operation with maintenance live line working process, operating personnel is often needed to enter the charged assembling and disassembling connecting line of highfield, after charged dismounting connecting line, maintainer can carry out power failure maintenance to isolating switch, rotary switch and vertical type switch etc., does not need operations staff to lead interval and load rejection.If but can not charged dismounting connecting line, then need to lead interval and load rejection, so operations staff needs operation more than 200 time at every turn, is easy to cause draw close by mistake by mistake, can cause large-area power-cuts, there is potential safety hazard and cause economic loss.And at present, the charged dismounting connecting line of operating personnel, need hang insulating ladder in double-bus keeps double-bus level, and in operating process, insulating ladder is easily deviate from from bus, all there is potential safety hazard to the person of operation field operating personnel and field apparatus.
Summary of the invention
The present invention is directed to above-mentioned problems of the prior art, provide a kind of transformer station double-bus and balance insulating ladder of sealing up a door, solve insulating ladder in prior art and easily deviate from from bus, there is 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 connect a support bar respectively, and the other end of two support bars fastens and forms tripod with crossbeam; 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, and nut outer surfaces welds whippletree.
Described insulation board is right-angled U.
Described crossbeam two ends are fixed by punching bolt and insulation board.
Described bolt end head is embedded in aluminium alloy plate inside, and it is fastening that aluminium alloy plate and bolt pass through set bolt.
Described bolt passes from the top of aluminium alloy plate.
Described groove is circular arc, and circular groove internal diameter and bus external diameter match.
Spacing between described groove and the spacing between bus match.
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, double-bus hangs after insulating ladder keeps double-bus level, insulating ladder to hang and be automatically locked, can prevent insulating ladder from deviating from from bus, improve field work safe, ensure that the person and device security.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
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, concrete structure of the present invention is described in detail.
embodiment 1
As shown in Figure 1, comprise insulating ladder body 11, the upper end of body arranges right-angled U 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 connect a support bar respectively, and the other end of two support bars fastens and forms tripod with crossbeam; 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 end head is embedded in aluminium alloy plate inside, and it is fastening that aluminium alloy plate and bolt pass through bolt 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 circular groove and the spacing between bus match; 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, and nut outer surfaces welds whippletree 6, 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.
Before using the present invention, between groove and whippletree, be in open mode.During use, insulating ladder body lower part is pushed down by surface personnel, operating personnel lifts insulating ladder body upper part in addition, vertical for insulating ladder straight, then lift insulating ladder and aim at the insertion of double-bus centre position, half-twist, circular groove aims at bus, hang in double-bus, at this moment the rotating insulated ladder of ground electrician makes the nut on whippletree moves, until whippletree seals circular groove, locked bus stops the rotation, adjustment insulating ladder angle, comfortable when 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, operation can be carried out.
The above know-why being specific embodiments of the invention and using, any based on the equivalent transformation on technical solution of the present invention basis, all belong within protection scope of the present invention.
