The device comprises a box which imitates the inflatable cabinet. The box is provided with a self-sealing valve installation hole and more than one insulator installation hole. Through using the testing device of the insulator voltage withstanding test of the utility model, sealing performance of the insulator can be detected and a usage environment of the insulator can be realistically simulated so that an obtained voltage withstanding test conclusion is accurate.
Description
Technical field
The utility model relates to a kind of proving installation, particularly a kind of insulator withstand voltage test proving installation.
Background technology
The inflation cabinet is that a kind of being filled with hanged down the working pressure insulating medium (like sulfur hexafluoride; SF6) casing; It isolates internal high pressure element and external environment condition through high voltage devices such as bus, isolating switch, disconnector, mutual inductor are sealed in the gas tank fully, does not receive the influence of external environment (like condensation, filth, toy, chemical substance etc.); Have non-maintaining or the reduced-maintenance characteristics, be widely applied in places such as mine, transformer stations.
Inflation generally all is provided with insulator cashier's office in a shop, and the cable of inlet wire and outlet electrically connects through insulator and inner high voltage device, therefore for insulator; Not only require good electric property; Have resistance to pressure preferably, also requirement can cooperate closely with the inflation cabinet, to guarantee the sealing of inflation cabinet.
At present; Insulator electrical performance test and withstand voltage properties test are all carried out in air or insulating oil usually; Break away from the inflation cabinet, can't effectively simulate the environment for use of insulator, it is this situation that is arranged in the inner insulating medium of inflation cabinet that main part that promptly can't analog insulation has half at least; Because existing method of testing can't guarantee insulator and inflation cabinet and can closely cooperate fully, therefore can't accurately assess the withstand voltage properties of insulator.
The utility model content
The purpose of the utility model provides a kind of insulator withstand voltage test proving installation, to solve in the prior art, can't effectively simulate the problem of insulator environment for use to the test of insulator.
The utility model proposes a kind of insulator withstand voltage test proving installation, is used to test the withstand voltage properties of the insulator that is used in the inflation cabinet, comprises the casing of simulation inflation cabinet, offers self-styled valve mounting hole and an above insulator mounting hole on the casing.
Further, described insulator withstand voltage test proving installation, it also comprises pressing plate, offers an above pressure-bearing hole on the pressing plate, the pressure-bearing hole is corresponding with the insulator position of mounting hole.
Further, casing is provided with an above backstay, offer an above pilot hole on the pressing plate, and backstay is corresponding with position of positioning hole.
Further, the relative distance between this insulator mounting hole and the inflation relative distance of assembling insulator cashier's office in a shop is consistent.
With respect to prior art; The beneficial effect of the utility model is: through the insulator withstand voltage test proving installation of the utility model; Both can detect the sealing property of insulator, environment for use that again can the real simulated insulator, thus make the withstand voltage test conclusion that obtains more accurate.
Description of drawings
Fig. 1 is a kind of embodiment synoptic diagram of the utility model insulator withstand voltage test proving installation;
Fig. 2 is installed to the synoptic diagram on the insulator withstand voltage test proving installation for the utility model insulator.
Embodiment
Specify the utility model below in conjunction with accompanying drawing.
See also Fig. 1 and Fig. 2, Fig. 1 is a kind of embodiment synoptic diagram of the utility model insulator withstand voltage test proving installation, and Fig. 2 is installed to the synoptic diagram on the insulator withstand voltage test proving installation for insulator.The insulator withstand voltage test proving installation of present embodiment is used to test the withstand voltage properties of the insulator 6 that is used in the inflation cabinet, and its main part is made up of the casing 1 of a simulation inflation cabinet, and the material of casing 1 and mentality of designing and inflation cabinet are consistent; On casing 1, offer a plurality of insulator mounting holes 2 (quantity of insulator mounting hole 2 is provided with according to actual needs); Be used to install insulator 6; The size of insulator mounting hole 2 should suit; So that after insulator 6 is installed to insulator mounting hole 2, it is identical with the part that is exposed after insulator 6 is assembled to the inflation cabinet that insulator 6 is exposed at the outer part of casing 1, and the relative distance that insulator 6 is assembled in the relative distance between the insulator mounting hole 2 and inflation cashier's office in a shop is consistent; On casing 1, also be provided with a self-styled valve mounting hole 3, be used to install self-styled valve.
In addition, on casing 1, also be provided with many backstays 4, backstay 4 preferred cloth be located at insulator mounting hole 2 around, the quantity of backstay 4 can design according to actual needs.
Insulator withstand voltage test proving installation also comprises a block pressur plate 5; Be used for insulator 6 is installed on the insulator mounting hole 2; Offer a plurality of pressure-bearings hole and a plurality of pilot hole on the pressing plate 5, the pressure-bearing hole is corresponding with the position and the quantity of insulator mounting hole 2, is used for cooperating installation insulator 6; Pilot hole is corresponding with the quantity and the position of backstay 4, wears the position of coming positioning pressuring plate 5 in the pilot hole through making backstay 4.
During the withstand voltage properties of test insulator 6, the first step utilizes pressing plate 5 that insulator 6 is installed on the insulator mounting hole 2, in installation process, to keep each several part on the pressing plate 5 stressed evenly, damage with the insulator of avoiding causing 6 because of unbalance stress; Second step, the self-styled valve 7 of installation on self-styled valve mounting hole 3, and joint detection equipment or instrument joint, this moment, insulator mounting hole 2 and self-styled valve mounting hole 3 were insulated son 6 and 7 sealings of self-styled valve respectively, in theory confined space of casing 1 inner formation; The 3rd step, through the checkout equipment test of hunting leak, detect the sealing in the casing 1, if insulator 6 can closely cooperate with insulator mounting hole 2, promptly casing 1 inside is in sealing state fully, then hunts leak and passes through; In the 4th step, after leak detection was passed through, to the casing 1 inner insulating medium that fills, insulating medium preferably adopted sulfur hexafluoride (SF6), the user mode of analog insulation 6 in the inflation cabinet; In the 5th step, through connecing checkout equipment insulator 6 is carried out withstand voltage test, and draw the whether qualified conclusion of insulator 6 withstand voltage properties at last.
Through the insulator withstand voltage test proving installation of the utility model, both can detect the sealing property of insulator, environment for use that again can the real simulated insulator, thus make the withstand voltage test conclusion that obtains more accurate.
Being merely the preferred embodiment of invention in sum, is not to be used for limiting practical range of the present invention.Be that all equivalences of doing according to the content of claim of the present invention change and modification, all should be technological category of the present invention.
