Description
Technical field
The present invention relates to a kind of device that live part in the High voltage power supply equipment and live part are not insulated and isolate, particularly a kind of high voltage isolator is employed insulated isolated device when one-sided charged the maintenance.
Background technology
Isolating switch is the visual plant in the transportion wire road, in carrying electric production process, need overhaul it sometimes.Guaranteeing to carry under the situation of electric operate as normal; Usually can run into and under the one-sided charged situation of isolating switch, to overhaul it; Life security in order to ensure operating personnel; Prior art generally is to adopt the mode of outage to overhaul, the problem to the influence of ordinary production and life that existing has a power failure brings.
Summary of the invention
The one-sided hotline maintenance seal of a kind of isolating switch provided by the invention has solved under the one-sided charged situation of isolating switch the problem to the influence of ordinary production and life that it is overhauled that existing has a power failure and brings.
The present invention solves above technical problem through following technical scheme:
The one-sided hotline maintenance seal of a kind of isolating switch comprises insulation board, T shape slide calliper rule, U-shaped deck and insulating bar, is provided with the insulation board draw-in groove at the cross-arm top of T shape slide calliper rule; The insulation board active card is connected in the insulation board draw-in groove; The U-shaped deck is provided with connecting bolt, and the montant of T shape slide calliper rule is provided with bolt hole, and connecting bolt is screwed onto in the bolt hole; Central authorities at the base plate of U-shaped deck are provided with nut; In nut, be provided with screw rod, pass the top of screw rod that nut enters into the U-lag of U-shaped deck and be provided with top board, the bottom of screw rod is screwed onto with the top of insulating bar.
The bolt hole that on the montant of T shape slide calliper rule, is provided with is a vertical setting of types, and described U-shaped deck is connected together through the base of U-lag and isolating switch.
The present invention has simple in structure, is convenient to install, the problem of personal security when efficiently solving the one-sided hotline maintenance of isolating switch.Can realize isolating switch (moving) contact side hotline maintenance (quiet) contact side, reduce because of isolating switch one side contact fault causes to have a power failure and use bus, cause a large amount of power failures.Improve amount of power supply and power supply reliability.

Embodiment
The one-sided hotline maintenance seal of a kind of isolating switch comprises insulation board 1, T shape slide calliper rule 2, U-shaped deck 3 and insulating bar 4, is provided with insulation board draw-in groove 5 at the cross-arm top of T shape slide calliper rule 2; Insulation board 1 active card is connected in the insulation board draw-in groove 5; U-shaped deck 3 is provided with connecting bolt 7, and the montant of T shape slide calliper rule 2 is provided with bolt hole 6, and connecting bolt 7 is screwed onto in the bolt hole 6; Central authorities at the base plate 8 of U-shaped deck 3 are provided with nut 9; In nut 9, be provided with screw rod 10, pass the top of screw rod 10 that nut 9 enters into the U-lag of U-shaped deck 3 and be provided with top board 11, the bottom of screw rod 10 is screwed onto with the top of insulating bar 4.
The bolt hole 6 that on the montant of T shape slide calliper rule 2, is provided with is a vertical setting of types; Adjustment connecting bolt 7 connects with different bolts hole 6 can adjust the high and low position of insulation board 1 in isolating switch; Described U-shaped deck 3 is connected together through the base of U-lag and isolating switch; Thereby rotary screw 10 reaches and raises or reduction top board 11, and the U-shaped deck 3 and the base of isolating switch closely are connected together, and makes whole seal reliable and stable.
During use, the cross-arm top that insulation board 1 is installed on T shape slide calliper rule 2 is provided with in the insulation board draw-in groove 5 available bolt.The link position of regulating up-down connecting bolt 7 and bolt hole 6 satisfies the installation of the isolating switch of different model.U-shaped deck 3 mounting boards on the transverse channel steels of isolating switch, are rotated insulating bar 4, and it is stuck with the transverse channel steels of isolating switch with top board 11 to drive screw rod 10, makes between the dynamic and static contact of isolating switch effectively to isolate, and has guaranteed maintainer's safety work.
Insulation board 1 is to be made by the epoxy resins insulation plate.Be to be directed against the 35kV isolating switch in the embodiment of the invention, the thickness that requires insulation board 1 is 5 millimeters, and length is 1200 millimeters, highly is 1000 millimeters.Insulation board draw-in groove 5 length that are provided with at the cross-arm top of T shape slide calliper rule 2 are 500 millimeters, and 2 holes are arranged on it, and available 2 bolts are fixed, and T shape slide calliper rule 2 are made by hardware, guarantee to have enough support strengths and anti-twist intensity.U-shaped deck 3 mainly plays the fixed insulation plate and connects the effect of the transverse channel steels of isolating switch; Move up and down through regulating connecting bolt 7 drive top boards 11; Can device well be stuck on the isolating switch transverse channel steels, assurance device can not rock on channel-section steel and cause that personnel get an electric shock.Insulating bar 4 is connected on the U-shaped deck 3 through screw socket, is convenient to personnel's the installing and fixing of finishing device on the safe distance that allows.Insulating bar 4 is to be not less than 40 millimeters epoxy rods making with diameter, and its length is the 1500-2000 millimeter.
