Abstract
The invention discloses an insulation device for overhauling an electric isolating switch. The insulation device comprises an insulating plate, wherein the insulating plate is blocked in a trough of a cross bar of a T-shaped supporting member; a vertical bar of the T-shaped supporting member is connected to a U-shaped blocking seat through a pin; the U-shaped blocking seat is connected to the upper end of an insulating operation tube; a pin hole for adjusting the height of the T-shaped supporting member relative to the U-shaped blocking seat is formed on the vertical bar of the T-shaped supporting member; a core bar is arranged in the insulating operation tube; the upper end of the core bar penetrates through one of side plates of the U-shaped blocking seat, and is provided with a stop piece; a compression spring is sleeved between the stop piece and the side plate of the U-shaped blocking seat on the core bar; a transverse supporting arm is arranged at the lower end of the core bar; and two ends of the transverse supporting arm extend out of holes on the side wall of the insulating operation tube. By the insulation device, reliable positioning of the insulating plate is realized, so that the insulating plate is effectively prevented from moving and contacting an electrified body, the personal safety of maintainers is ensured, and the insulation device is convenient to operate.
Description
Technical field
The invention belongs to the electric power tool technical field, relate in particular to the electric isolating switch insulation device used for examining and repairing.
Background technology
In the work of electric power system substation equipment maintenance and repair, in the situation that guarantee to carry the electricity normal operation, usually running into need to be in the situation that isolating switch be one-sided charged it is overhauled, life security in order to ensure operating personnel, modal in the prior art is to adopt the mode of outage to overhaul, and power failure brings impact can for normal production, life.
In 110kV and following electric power system substation equipment maintenance and repair, because bus or circuit can't have a power failure, when a side has cooperating and isolating switch has a power failure, the customary insulation baffle plate is placed on the personal safety of guaranteeing the maintainer between the moving contact and fixed contact of isolating switch, insulation barrier is exactly a simple rectangular plastic plate, when on pile crown, not working, insulation barrier is swung to power failure contact one side, and when pile crown has work, insulation barrier then need be swung to band electrical contact one side, and insulation barrier can not reliably be located on pile crown, and insulation barrier often directly contacts with electrified body, can not guarantee enough safe distances when the maintainer works, cause potential safety hazard to service work.
Summary of the invention
The purpose of this invention is to provide and a kind ofly can realize reliable location, handled easily is guaranteed the electric isolating switch insulation device used for examining and repairing of handling safety.
The technical scheme that the present invention takes is: a kind of electric isolating switch insulation device used for examining and repairing, comprise insulation board, insulation board is connected in the draw-in groove of cross bar of T shape strutting piece, T shape strutting piece is connected on the U-shaped deck by pin, U-shaped deck is connected to the upper end of insulation operation pipe, the montant of T shape strutting piece is provided with can regulate T shape strutting piece with respect to the pin-and-hole of the height of U-shaped deck, in the insulation operation pipe core bar is housed, one of them side plate of U-shaped deck is passed in the upper end of core bar, the upper end of core bar is equipped with block, between block and U-shaped deck side plate, be set with Compress Spring on the core bar, the lower end of core bar is provided with lateral arms, and the hole on the insulation operation pipe sidewall is stretched out at the lateral arms two ends.
Maintainer's one hand-held insulation operation pipe during use, insulation board is connected in the draw-in groove of cross bar of T shape strutting piece, regulate T shape strutting piece with respect to the height of U-shaped deck, lift insulation operation pipe, make insulation board near the transverse channel steels of isolating switch, insulation board is placed between the moving contact and fixed contact of isolating switch, the another hand pulls down the lateral arms of core bar, the transverse channel steels of isolating switch is entered above the block on U-shaped deck internal core rod top, then loose one's grip, under the effect of Compress Spring, the block on core bar top moves up the transverse channel steels of isolating switch is blocked, insulation board just reliably has been positioned between the dynamic/static contact of isolating switch, and the maintainer just can begin to have carried out inspection operation.After service work is finished, pull down the lateral arms of core bar, Compress Spring is further compressed, and the block on core bar top moves down, and at this moment just whole device can be taken off from the transverse channel steels of isolating switch.
The two ends of insulation board are connected with the isosceles triangle seat board, and insulation board is perpendicular to the bottom surface of isosceles triangle seat board.Allow the isosceles triangle seat board be positioned at the isolating switch outside during use, prevent that insulation board from moving, increase the stability of insulation board, play the effect of double insurance.
The present invention is because the reliable location of having realized insulation board, the movement that can effectively prevent insulation board with the contacting of electrified body, guaranteed maintainer's personal safety, easy to operate.
