Description
Technical field
The utility model is related to GIS device service kit fields, specially GIS device disconnecting link, earthing knife-switch electric operating tool.
Background technology
HGIS/GIS equipment disconnecting link, earthing knife-switch are operated usually using motor-operating mechanism, but due to equipment disconnecting link, earthing knife-switch
Motor-operating mechanism failure when can not carry out electric operating, then needs the mechanically actuated bar being equipped with using producer or handle to carry out
Manual operation.In fact, due to Wuping station plant equipment problem, (alternating current generator route problem causes disconnecting link earthing knife-switch stuck, electricity
Machine damages) using more the case where manual operation.Since the manual operation needs that HGIS/GIS equipment disconnecting link, earthing knife-switch use are hand
The number of turns it is more, manually operated using operating rocker handle, time and effort consuming and exist damage equipment risk.
By taking HGIS/GIS equipment disconnecting link, earthing knife-switch as an example, Siemens HGIS equipment disconnecting link, earthing knife-switch, by the electronic behaviour of closed position
Make to unzipped positions, it is necessary first to open one by 6 fixed cover boards of hex screw, then need to turn on two bolts and fix
Operation hole capping, finally using producer configure hand-operated tools manually shake 350 to 400 circle, can just pull open a phase disconnecting link,
Knife, and operate pull open after there is still a need for operation hole capping and fixed cover board is covered, verified by practical operation, only electric operating pulls open
One earthing knife-switch just needs two people to spend 45 minutes to 1 hour.It can be seen that carrying out electric operating using the specific purpose tool that producer is equipped with needs
Considerable time it cannot meet the requirement for fast and safely operating equipment especially in emergency situations such as process accidents.
It is restricted to driving torque such as when HGIS/GIS equipment electric operatings, such as Siemens HGIS equipment requirement torques
No more than 50N, existing tool is unable to control torque, equipment mechanism may be caused to damage if being operated more than the driving torque upper limit
It is bad.Once mechanism damage needs to contact producer technical staff and coordinate that equipment power failure is arranged to carry out integrated model replacement, to equipment
And power grid will all impact.Stroke all processes debugging in advance of disconnecting link, earthing knife-switch, can ensure under normal circumstances when electric operating
Opening and closing in place, when manually carrying out electric operating, operation quality can lack experience because of operating personnel, misoperation or strength are inadequate
Etc. reasons and be affected, be easy division it is not in place, cause injury to personnel or damage equipment adverse consequences.
The electric operating tool of different manufacturers is different, not general, preserves, management, safeguards, is more using being required to
Manpower and materials, inefficiency.

The center of position block is equipped with the second through-hole that internal diameter is more than the first polished rod portion outer diameter；The inside of the outer sleeve is divided into
Big hole portion, small hole portion；First limited block, butterfly spring are inserted in the first polished rod portion of torsion cylinder successively, and described first
Second card slot of limited block and the first card slot of blocking part face and are equipped with described between the first card slot and the first card slot one by one
Steel ball；The external thread part of the adjusting bolt sequentially passes through first from the side of the connecting hole of electric wrench connecting cylinder and leads to
Hole, the second limited block the second through-hole be threadedly coupled with the internal thread hole in the first polished rod portion of torsion cylinder, the torsion cylinder,
One limited block, steel ball, butterfly spring, the second limited block, electric wrench connecting cylinder are installed together by adjusting bolt, described
The big hole portion of outer sleeve is inserted in from the second polished rod portion side of torsion cylinder, and the blocking part of torsion cylinder is supported away from one end of the first card slot
It keeps off on the end face between big hole portion and small hole portion, the second polished rod portion of torsion cylinder penetrates the interior angle in small hole portion and the second polished rod portion
Outwardly, first limited block, butterfly spring, the second limited block, electric wrench connecting cylinder, adjusting bolt are installed in outer in hole
In the big hole portion of jacket casing and the connecting hole of electric wrench connecting cylinder outwardly.
As the improvement of said program, limit is additionally provided between first limited block and the blocking part of torsion cylinder
Ring, equipped with multiple and the first groove position relationship one-to-one correspondence and internal diameter and the major diameter fit of the steel ball on spacing ring
Limit hole.
As the improvement of said program, the interior corner apertures is interior 12 corner apertures, by two positive six face shapes, 30 degree of intersections
It is formed.
As the improvement of said program, the section of first card slot is isosceles triangle.
The utility model has the advantages that：
1. tool is light-weight, working service is convenient；It only needs to carry a tool box when use, you can to different manufacturers difference
The HGIS/GIS equipment disconnecting link earthing knife-switch of model is operated.Through practical probation, operable 8 groups of monoblock battery single totally 24 phase is used
Disconnecting link earthing knife-switch fully meets the various burst operation demands in scene.
2. operating efficiency greatly improves；If being operated using the operation instrument that producer is equipped with, verified, only electric operating
Pulling open an earthing knife-switch just needs two people to spend 45 minutes to 1 hour, and is operated only using the electric tool of the utility model
