Description
Technical field
The utility model relates to a kind of High-Voltage Electrical Appliances assembly, and it is the gas-filled type turnover thread casing that uses in potting breaker and the Cubicle Gas-Insulated Switchgear (GIS), and particularly the gas-filled type about the 800kV electric pressure passes in and out thread casing.
Background technology
The turnover thread casing all has use in the potting breaker of other electric pressure and GIS, high voltage can be incorporated in the corresponding apparatus by this assembly.Along with the raising of electric pressure, length, design and the manufacture difficulty of gas-filled type turnover thread casing all increasing, and also will increase as the length of the center conductor of one of its main composition parts thereupon.The center conductor length of the gas-filled type turnover thread casing of the following electric pressure of 800kV generally below 6m, is overall structure.But gas-filled type turnover thread casing for the 800kV electric pressure, the length of its center conductor reaches 9m-11m, if still adopt overall structure, all brought very big difficulty will for processing, transhipment and keeping, the economy of whole turnover thread casing also can be affected simultaneously.
Summary of the invention
The purpose of this utility model provides a kind of 800kV gas-filled type turnover thread casing, and its center conductor adopts special structure, can shorten the processing length of center conductor, and the bonding strength height makes center conductor processing, transhipment, keeping and installs all very convenient; And both guaranteed the galvanization ability under the operating state; Also reduced the manufacturing cost of center conductor.
The purpose of this utility model is to realize like this, design a kind of gas-filled type turnover thread casing, it is characterized in that: center conductor is to be connected and composed by center conductor bottom 6 and center conductor top 8, and there is the flange of being with shielding construction the end that is connected on center conductor bottom 6 and center conductor top 8; Earth shield tube 5 is fixed on the ground connection flange 2, intershield tube 4 is fixed on the ground connection flange 2 by insulation supporting rod 1, ground connection flange 2 is fixedlyed connected with insulator lower flange 3, center conductor bottom 6 is enclosed within the intershield tube 4, intershield tube 4 is enclosed within the earth shield tube 5, center conductor, earth shield tube 5, intershield tube 4 are enclosed within the insulator 7, and coaxial with insulator 7; Center conductor is fixed on the insulator upper flange 10 by flange, and shading ring 9 also is fixed on the insulator upper flange 10.
There is the flange of band shielding construction described center conductor end, and the outer rim of flange has the crooked edge of extension downwards, is with cavity between curved down edge and the conductor pin, and bolt connecting hole is arranged in the cavity, and bolt 11 shieldings that connect usefulness are in cavity.
Characteristics of the present utility model are: two parts linked together by the shielding flange about this its center conductor of gas-filled type turnover thread casing was divided into, the earth shield tube is fixed on the same flange, the intershield tube also is fixed on the same ground connection flange by the insulation supporting rod, guarantee the isolation of electric aspect, this ground connection flange and insulator lower flange are fixed, and make intershield tube, earth shield tube, insulator form one group of same axis body; Center conductor passes the axle center of this group with axis body.Center conductor is in high potential, by adjusting the diameter and the length of earth shield tube, intershield tube, can make the electric field strength on center conductor and insulator surface satisfy engineering demand.For center conductor, two-part up and down termination all is designed to have the flange of shielding construction, with bolt flange is linked together, promptly becomes one.The shielding cylinder that two certain-lengths are arranged between center conductor and insulator.Its advantage be the length of every part of center conductor all within 5m～6m, processing, transportation and keeping are all more convenient, but for whole turnover thread casing, adopting the assembly type conductor still be that integral conductors is not distinguished its performance.The utlity model has following characteristics:
1, center conductor adopts the dismantled and assembled structure of shielding flange join type, and it can shorten the processing length of center conductor, and is simple in structure, and bonding strength height, center conductor are processed, transport, taken care of and install all very convenient.
2,, guarantee that the electric field strength at its lower flange place satisfies engineering demand under the less situation of insulator internal diameter by installing two-layer shielding cylinder additional in insulator inside.
