Description
Technical field
The present invention relates to electrical equipment field, specifically 10 ~ 220kV weighting meter.
Background technology
Insulating bar is that power equipment runs and requisite managing security tools and instruments in maintenance process, divides, closes and keep apart
Closing, hang, dismounting ground wire, high potential test for electric equipment wiring, the operation such as high-tension line charged verification phase place, phase sequence is required for using
To insulating bar.Insulating bar can make the effective position charged with electrical equipment of human body and may be separated by charged position
From, reduce the generation of electrical sensation electrification.
Grid condition is complex, and new and old transformer station exists simultaneously, and power transformation station equipment varies, only from chopper one
For Xiang, exist in a regional power grid to up-to-date HGIS equipment from old-fashioned oil-minimum breaker, transformer the most simultaneously, lightning-arrest
The pattern of device is the most multifarious, and corresponding binding post is also of all kinds.Conventional insulator action bars function singleness, every kind absolutely
Edge bar only can be used on corresponding equipment, and the function causing insulating bar pattern mixes, of a great variety.
For transformer station's operation maintenance personnel, each transformer station at least needs two groups of extensions, the ground wire bar tearing ground wire open and two groups
Insulated tension pole, some old-fashioned power transformation also needs to hang the insulating bar of fuse switch, installs insulating bar of insulating boot etc..Few
Station group to preserve and to safeguard four groups of (12-16 joint) insulating bars, many needs safeguards eight groups of (24-32 joint) insulating bars.Need every year
These insulating bars delivered to test unit in two batches and to carry out preventive trial, need during regular job to shoulder some groups exhausted
Edge bar is hurried back and forth in plant area, consumes extra manpower, material resources and financial resources.
Along with innovation and the development of electrical equipment in recent years, the carrying out of Transfomer Substation Reconstruction engineering, a large amount of throwings of novel device
Entering to use, the model of same electric equipment is also multifarious, and the mode of connection is varied, traditional high altitude test junction pole
Cannot meet diversified electrical equipment.It addition, during on-the-spot commissioning test, many times equipment the standard that not up to puts into operation,
Fixture wire and connection row are not connected with equipment mostly, and this also makes traditional high altitude test junction pole have no ample scope for abilities, only
Can be ascended a height by testing crew and go joint test wiring on equipment frame.This safety virtually increasing falling from high altitude is hidden
Suffer from.
Such as: a kind of novel 66kV spark gap upper end binding post, when being not connected with lead-in wire and wire clamp, traditional wired bar
It is difficult to test connection to be connected firmly.And for example: operating 66kV voltage transformer, when check is tested, lead-in wire is same
Being not connected to equipment, traditional wired bar is stymied by equally, just can only test by testing crew wiring of ascending a height.Give test
Personnel bring potential safety hazard, have also dragged slowly test progress simultaneously.
For these problems, prior art does not propose effective solution, for absolutely in currently available technology
The improvement of edge bar all concentrates on and improves the functional of head, but the today maked rapid progress in renewal of the equipment, want to make one omnipotent
Head the most impossible.

As shown in figure 12, described instrument is the support arm of adjustable-angle.Difference according to regulation angle can realize installing old-fashioned
The insulating boot of disconnecting switch, changes 66kV fuse switch, changes the operations such as 10kV fuse switch.
As shown in figure 13, described instrument is the binding post with multiple cable clamping interfaces.It is applicable to 220kV transformator height sleeve pipe remove
Ramp and mounting test connection.
As shown in figure 14, described instrument is the becket of adjustable perimeter.The size of regulation becket can be suitable for and have
Binding post or line bank but be not connected with the spark gap of lead-in wire, transformer, wait the test connection of electrical equipment.
As shown in figure 15, described instrument is telescopically adjustable wiring hook.The length of regulation wiring hook can complete line bank
With the most uninstalled voltage transformer that goes between, the test of the electric equipments such as current transformer.
Along with putting into operation of electrical equipment new-type in practical work, the bar of applicable equipment can be made targetedly
Head, without changing insulating bar body.
The present invention can also carry out expanding function in many-side, for example, it is possible to and electroscope, discharging rod, overhead jointing clamp
Etc. combining, it is also possible to expansive approach to transmission of electricity, distribution specialty, such as, can measure bar with null value and combine, the operation of box change
Handles etc. the most likely combine with the design application, expand space and application prospect is the most wide.By existing transformer station
Minimum insulating bar quantity four groups (12-16 joint) calculates, and after the design comes into operation, only needs two groups (6-8 joint) to insulate in standing
Bar can meet the demand run and safeguard, saves Financial cost and labour cost 50%, as according to most calculating, then can save
About cost more than 75%.The number of times of ascending a height of testing crew can be significantly reduced at secure context, the hidden danger of falling from high altitude is dropped to
Minimum.
Being described in detail the present invention above in association with accompanying drawing embodiment, those skilled in the art can be according to upper
State and bright the present invention is made many variations example.Thus, some details in embodiment should not constitute limitation of the invention, this
Invent the scope that defines using appended claims as protection scope of the present invention.
