Description
Technical field
The present invention relates to a kind of with the live part in the High voltage power supply equipment and live part not the insulate device of isolation, particularly a kind of high voltage isolator 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, sometimes needs it is overhauled.In the situation that guarantee to carry the electricity normal operation; usually can run 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; prior art generally is to adopt the mode of outage to overhaul, the problem on the impact of normal production and life that existing has a power failure brings.
Summary of the invention
The one-sided electrified maintenance insulated device solves of a kind of isolating switch provided by the invention charged it is overhauled the problem on the impact of normal production and life that exist to have a power failure and to bring in the situation that isolating switch is one-sided.
The present invention solves above technical problem by the following technical programs:
The one-sided electrified maintenance insulated device of a kind of isolating switch, comprise insulation board, T shape slide calliper rule, U-shaped deck and insulating bar, cross-arm top at T shape slide calliper rule is provided with the insulation board draw-in groove, the insulation board active card is connected in the insulation board draw-in groove, be provided with connecting bolt at the U-shaped deck, montant at T shape slide calliper rule is provided with bolt hole, 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 arranges at the montant of T shape slide calliper rule is a vertical setting of types, and described U-shaped deck is connected together by the base of U-lag and isolating switch.
The present invention has simple in structure, is convenient to the problem of personal security when efficiently solving the one-sided hotline maintenance of isolating switch is installed.Can realize isolating switch (moving) contact side hotline maintenance (quiet) contact side, reduce because 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 electrified maintenance insulated device of a kind of isolating switch, comprise insulation board 1, T shape slide calliper rule 2, U-shaped deck 3 and insulating bar 4, cross-arm top at T shape slide calliper rule 2 is provided with insulation board draw-in groove 5, insulation board 1 active card is connected in the insulation board draw-in groove 5, be provided with connecting bolt 7 at U-shaped deck 3, montant at T shape slide calliper rule 2 is provided with bolt hole 6, 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 arranges at the montant of T shape slide calliper rule 2 is a vertical setting of types, adjusting connecting bolt 7 is the high and low position of capable of regulating insulation board 1 in isolating switch with different bolt hole 6 connections, described U-shaped deck 3 is connected together by the base of U-lag and isolating switch, thereby rotary screw 10 reaches and raises or reduction top board 11, U-shaped deck 3 and the base of isolating switch closely are connected together, make 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, and available bolt is fixed.The link position of regulating lifting 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, drive screw rod 10 top board 11 is stuck with the transverse channel steels of isolating switch, make effectively isolation between the dynamic and static contact of isolating switch, guaranteed maintainer's safety work.
Insulation board 1 is to be made by the epoxy resins insulation plate.For the 35kV isolating switch, the thickness that requires insulation board 1 is 5 millimeters in the embodiment of the invention, and length is 1200 millimeters, highly is 1000 millimeters.Insulation board draw-in groove 5 length that arrange 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, ensure 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 by regulating connecting bolt 7 drive top boards 11, device well can be stuck on the isolating switch transverse channel steels, assurance device can not rock at channel-section steel and cause that personnel get an electric shock.Insulating bar 4 is connected on the U-shaped deck 3 by screw socket, and the installation of being convenient to personnel's finishing device on the safe distance that allows is fixed.Insulating bar 4 is to be not less than 40 millimeters epoxy rods making with diameter, and its length is the 1500-2000 millimeter.
