Description
Technical field
The utility model relates to a kind of insulation bracing frame that high-voltage connection is arranged when improving AC voltage withstand test.
Background technology
AC voltage withstand test is to identify the most direct method of insulation of electrical installation intensity, and can it put into operation for the judgement electrical equipment and have decisive meaning, also is the important means that guarantees apparatus insulated level, avoids taking place insulation fault.
Though a series of non-destructive testing (NDT)s that electrical equipment is carried out (insulation resistance and absorption ratio test, dielectric loss test, direct current leakage current testing), can find the SI semi-insulation defective, but because of these trial voltages generally lower, often insensitive to the reaction of some local defects, and these local defects are in operation and may develop into the serious hidden danger that influences safe operation gradually.May develop into general defect or local defect gradually as the shelf depreciation defective, under over-voltage condition, make equipment lose insulating property and accidents caused.Therefore, for the sensitiveer local defect of finding effectively, various superpotential abilities are born in the insulation of test test specimen, just must carry out AC voltage withstand test to test specimen.
When 10 ~ 220kV electrical equipment is carried out AC voltage withstand test, to couple together with high-voltage connection between the high pressure of testing equipment output and the test specimen and just can test, wherein the layout of the high-voltage connection stable experimental safe that rationally has a strong impact on whether.For carrying out smoothly of warranty test, when arranging high-voltage connection, must high-voltage connection is unsettled, and with the safe distance that keeps all around more than 1.5 meters.
The customary practice of in the past arranging high-voltage connection is to use that the insulation rope is horizontal on the path of high-voltage connection process to draw perpendicular hanging, make high-voltage connection and keep enough safe distance all around, but there are two problems in this way: one is to use the insulation rope as backguy, it is cumbersome arrange, neither attractive in appearancely lowers efficiency again; The 2nd, may there be suitable local fixed insulation rope near some test sites.
Therefore we need a kind of more effective equipment to be used for fixedly high-voltage connection.
The utility model content
For addressing the above problem, the purpose of this utility model is to provide a kind of insulation bracing frame that high-voltage connection is arranged when improving AC voltage withstand test.
The technical scheme that the invention for solving the technical problem adopts is:
A kind of insulation bracing frame that high-voltage connection is arranged when improving AC voltage withstand test comprises with lower member:
Insulating bar, described insulating bar is used for fixedly high-voltage connection;
The insulating bar bracing frame, described insulating bar bracing frame is arranged on the insulating bar below, and the insulating bar bracing frame comprises leg and be used for installing the connecting pipe of insulating bar that described leg is provided with three, and be triangularly arranged and be distributed in the connecting pipe side, an end of described leg is hinged on the connecting pipe.
The beneficial effects of the utility model are: insulation bracing frame of the present utility model can adapt to abominable site environment, changeable test site, not only convenient but also attractive in appearance, and the Layout Problem of high-voltage connection when having solved AC voltage withstand test reliably.After using insulation bracing frame of the present utility model, the layout of high-voltage connection becomes simple and convenient during AC voltage withstand test, no longer is subjected to the restriction in environment place, increases work efficiency greatly.
As further improvement in the technical proposal, described insulating bar is provided with for the folder that clamps high-voltage connection.Adopt folder to clamp high-voltage connection, can make two high-voltage connections between the insulating bar exceptionally straight, the vertical arch problem that produces thereby the solution high-voltage connection is long.
As further improvement in the technical proposal, described leg below is provided with the insulation rubber cushion, and described insulation rubber cushion at least can the anti-voltage that exchanges 35kV, the effectively insulating property of reinforced insulation bracing frame.
As further improvement in the technical proposal, be respectively arranged with between described three legs and the connecting pipe for the restriction leg and open the gag lever post of distance.Gag lever post defines the distance of opening of leg, and three gag lever posts are preferably set to the length unanimity, is convenient to leg and opens identical distance, forms stable support.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing and example.
Fig. 1 is structural representation of the present utility model.
Embodiment
With reference to Fig. 1, a kind of insulation bracing frame that high-voltage connection is arranged when improving AC voltage withstand test of the present utility model comprises insulating bar 1 and insulating bar bracing frame 2.Insulating bar 1 is arranged on insulating bar bracing frame 2 tops, and insulating bar 1 is provided with for the folder 3 that clamps high-voltage connection.Insulating bar bracing frame 2 is made up of connecting pipe 21 and three legs 22, connecting pipe 21 inside are provided with cavity and are used for grafting insulating bar 1, three legs 22 are triangularly arranged and are distributed in connecting pipe 21 sides, one end of leg 22 is hinged on the connecting pipe 21, its other end can open and form firm bracing frame, in addition, also be provided with between leg 22 and the connecting pipe 21 for the restriction leg 22 open the gag lever post 23 of distance.
Further, leg 22 belows are provided with insulation rubber cushion 4, and described insulation rubber cushion 4 at least can the anti-voltage that exchanges 35kV, the effectively insulating property of reinforced insulation bracing frame.
Insulation bracing frame of the present utility model can adapt to abominable site environment, changeable test site, not only convenient but also attractive in appearance, and the Layout Problem of high-voltage connection when having solved AC voltage withstand test reliably.After using insulation bracing frame of the present utility model, the layout of high-voltage connection becomes simple and convenient during AC voltage withstand test, no longer is subjected to the restriction in environment place, increases work efficiency greatly.
The above is preferred embodiment of the present utility model, and the utility model is not limited to above-mentioned embodiment, as long as it reaches technique effect of the present utility model with identical means, all should belong to protection domain of the present utility model.
