Description
Technical field
The invention belongs to electric power apparatus examination technical fields, more particularly to a kind of improved electric power isolation switch band electric-examination
Repair tool.
Background technology
Substation's mesohigh isolated switchgear can normal operation depend greatly on isolation switch contact
Contact resistance (general to require in 100 micro-ohms or so).It is affected by the surrounding environment with the growth of operation hours, such as work
Industry pollution from exhaust emission, especially chemical emission exhaust emission, salt-alkali contaminated corrosion, long oxidation corrosion etc. so that isolation
The gradual corrosion of switch contact conductive contact surfaces, surface forms layer of oxide layer, until making contact resistance increase, in normal operation
Contact calorific value increases under operating mode, and temperature increases, and so that corrosion oxide layer is aggravated again as temperature increases, causes contact resistance
And then increase, foring contact resistance bigger, --- fever higher --- temperature rises higher --- corrosion oxidation is pernicious faster to follow
Ring.It is happened occasionally in operation because corrosion causes isolation switch contact to burn out, scorification accident, so that needing replacing the whole of disconnecting switch
Body component causes great economic loss.It is set therefore, it is necessary to periodically will just can guarantee after the schmutzband grinding process of contact surface
Standby normal operation.To prevent disconnecting switch because dirt, corrosion cause contact to burn out accident, infrared imaging inspection device is mainly used

Mill processing, when processing the power failure of the dynamic and static contact both sides of disconnecting switch generally require the stoppage in transit of whole section of busbar.Therefore, it is arrangement one
Platform isolation switch contact overhaul, need cumbersome grid switching operation, the safety measure etc. of artificial high-altitude grinding process need to spend it is very long
Power off time, not only expend huge man power and material, there are higher personal safety risk and job safety risk, it is also tight
Ghost image rings multiple power supply, influences power supply reliability.
There has been a kind of electrification polishing service kits, by insulating support rod as supportive body, insulating bar
It is connect with the insulating support rod by lifting part, the height of insulating bar operation can be controlled by lifting part, absolutely
One end of edge operating lever is equipped with polishing wheel, and the polishing wheel is by transmission shaft and the driving in the insulating bar other end is arranged
Motor connects, and operating personnel can start driving motor control polishing wheel rotation on ground, to the electric power in high-altitude every
It is cleared up from disconnecting link, need not have a power failure, be not necessarily to personal height operation, but there is also some significant deficiencies for this invention.At present
Using electrification polishing service kit, operating personnel is in ground and operates grinding wheel polishing disconnecting link contact by insulating bar, because
With the polishing object distance of eminence farther out, insulating bar it is long, when polishing operation, is difficult to adjust polishing dynamics and position so that
Current milling tools is difficult to reach ideal polishing effect.

Make one end of bar, the other end in insulating bar is arranged in the driving motor, and the polishing wheel passes through transmission shaft and driving electricity
Machine connects, which is additionally provided with dust excluding plate, insulation auxiliary rod, universal joint, and the dust excluding plate is mounted on insulating bar and polishing
The junction of wheel, the universal joint are arranged on dust excluding plate, and the insulation auxiliary rod is coupled by universal joint with insulating bar.
Increase an insulation auxiliary rod, which passes through universal joint at the top of insulating bar and insulation
Operating lever couples, and can be adjusted to the position that polishing wheel is polished by universal joint when polishing wheel carries out polishing operation.
Operating personnel can support polishing wheel when polishing by the auxiliary rod that insulate, the more branch of the service kit mutually having relatively
Support point, sharing the gravity born on insulating bar makes operating personnel more easily control manipulate polishing wheel, can be according to the journey of polishing
Degree adjusts polishing dynamics by insulating bar, while to prevent polishing dust from falling into bar operating personnel, in polishing wheel
The suitable dust excluding plate of a block size is arranged in lower section.
Further, lifting part includes pulley, insulating cord, manual reel, and the pulley is fixed on the top of insulating support rod
Portion, the manual reel are fixed on the bottom of insulating support rod, and the insulating cord passes through pulley one end to connect insulating bar, separately
One end connects manual reel.The height of insulating bar operation can be controlled by lifting part.
Further, insulation auxiliary rod includes scalable insulation auxiliary rod.Telescopic insulating bar can be according to being beaten
The position of mill is adjusted length, the polishing position of preferably fixed polishing wheel.
Further, dust excluding plate is rectangle, and baffle is equipped on four sides of the dust excluding plate.Prevent polishing dust from flying everywhere
It dissipates.
Further, the one end of insulation auxiliary rod far from universal joint is equipped with non-skid band.It prevents when operating personnel operate
The auxiliary rod that do not insulate tightly is grabbed because of rubber sleeve.
Further, insulating bar is hollow structure, and the transmission shaft is arranged in insulating bar.Transmission shaft is surrounded
It in insulating bar, prevents transmission shaft from accidentally being touched influence polishing operation by operating personnel, while ensuring operating personnel's upkeep operation
Safety.
The beneficial effects of the invention are as follows；Insulation auxiliary rod and dust excluding plate are increased on existing service kit, insulation is auxiliary
Bar is helped to couple with insulating bar by the universal joint at the top of insulating bar, while to prevent polishing dust from falling into behaviour
Make with personnel, the suitable dust excluding plate of a block size is set below polishing wheel.Improved service kit, makes operating personnel can
It need not be stopped to clear up the electric power isolation switch in high-altitude with starting driving motor control polishing wheel rotation on ground
Electricity is not necessarily to personal height operation, while the auxiliary rod that can be insulated by operation in polishing operation, on the one hand can facilitate adjustment
Polishing dynamics increases polishing dynamics, on the other hand can preferably fix polishing position, so as to improve polishing effect.
