Abstract
An inverted gas-insulated voltage transformer testing device for GISs comprises a metal tank body, a high-voltage insulation casing arranged on the tank body, and a connection transition tank arranged on the tank body and capable of being conveniently connected with a voltage transformer needing to be tested, wherein basin-type insulators are respectively arranged between the metal tank body and the high-voltage insulation casing and between the metal tank body and the connection transition tank. When the device is in use, the voltage transformer needing to be tested is connected with the connection transition tank arranged on the metal tank body, and the high-voltage insulation casing and the metal tank body are filled with SF6 gas, through which high voltage is exerted on the voltage transformer needing to be tested so as to complete a test on the voltage transformer needing to be tested. When a next voltage transformer needing to be tested is tested, sealing is carried out through the basin-type insulators. What needs to do for each test is to fill and recycle SF6 gas in the connection transition tank, and the only step needing to be taken is to carry out vacuum pumping on the connection transition tank. Each test is carried out without the need of disassembling and assembling the high-voltage casing and filling and recycling SF6 gas in the high-voltage casing. Therefore, the operation is simple, the working efficiency high, energy is saved and waste of SF6 gas is prevented.
Description
Technical field
The utility model relate to a kind of GIS extra-high voltage combined electrical apparatus with inverted GIS with gas-insulated voltage transformer (VT) test unit.
Background technology
High pressure combined electrical apparatus gas-insulated electromagnetic potential transformer, conventional test method is with voltage transformer (VT) disc insulator upper end high-tension insulating bushing to be installed at GIS high pressure combined electrical apparatus, must be at every turn dismounting bushings all, and must each test fill and reclaim SF6 gas to bushing, the operating process time is long, and electric energy and the waste of SF6 gas are big.
Summary of the invention
In view of the deficiency that above-mentioned prior art exists, the inverted GIS gas-insulated voltage transformer (VT) test unit that the purpose of this utility model provides a kind of SF6 of preventing gas waste and can increase work efficiency.
The purpose of this utility model be achieved in that it on comprising metal can and placing this tank body high-tension insulating bushing and be convenient to be connected the connection transition jar that needs the trial voltage mutual inductor, at metal can with high-tension insulating bushing be connected between the transition jar and be respectively equipped with disc insulator.During use, the transition jar that is connected on need trial voltage mutual inductor and the metal can is connected, in high-tension insulating bushing and metal can, fill SF6 gas, apply high tension voltage by it to need trial voltage mutual inductor, finish test to need trial voltage mutual inductor with this.When doing next and need the trial voltage mutual inductor, by the disc insulator sealing, each test only needs to fill and reclaim the SF6 gas in the transition jar, and only the transition jar is vacuumized and get final product.
The utility model has the advantages that each test only need fill and reclaim the SF6 gas in the transition jar, and only the transition jar is vacuumized and get final product, need not the dismounting bushing at every turn and SF6 gas is filled and reclaimed to bushing, thereby it is easy and simple to handle, high efficiency, saves energy prevents the waste of SF6 gas.
Below in conjunction with accompanying drawing the utility model is described further.
Description of drawings
Fig. 1 is inverted GIS gas-insulated voltage transformer (VT) test unit structural representation.
Embodiment
By accompanying drawing as can be known, this inverted GIS is made of metal can 3, high-tension insulating bushing 1, connection transition jar 5 and disc insulator 2,6 with gas-insulated voltage transformer (VT) test unit.High-tension insulating bushing 1 places on the metal can 3 by disc insulator 2, connects transition jar 5 and places on the metal can 3 by disc insulator 6.Metal can 3 is as the supporter as bushing 1 and voltage transformer (VT) 4.Need be connected with metal can 3 by connecting transition jar 5 by trial voltage mutual inductor 4 during use, in high-tension insulating bushing 1 and metal can 3, fill SF6 gas, apply high tension voltage by it to need trial voltage mutual inductor 4, finish test to need trial voltage mutual inductor with this.By adjust with change test unit on be connected transition jar 5, can satisfy the testing requirements of different electric pressures (comprising 66kV, 110kV, 220kV and 500kV UHV (ultra-high voltage) GIS voltage transformer (VT)).By disc insulator 2,6 sealings, each test only needs to fill and reclaim the SF6 gas that is connected in the transition jar 5, and only the transition jar is vacuumized and get final product.
