Abstract
The utility model relates to a tube bus GIS terminal head. Two ends of a conductor are respectively provided with a GIS connector and a tube bus connector, an insulator is cast outside the middle part of the conductor, the middle of the conductor is provided with an outer boss, a fixing bolt hole and a sealing groove are arranged on the outer boss, the periphery of a flange is provided with an insulation shielding cylinder fixing bolt hole, and the flange is fixed on the outer boss through the fixing bolt hole, and the insulator is cast in a fixing groove of the conductor and is fixed on the conductor. According to the utility model, by making use of electric conduction of the conductor, insulation of the insulator and the sealing function of the flange, the fixing bolt hole and the sealing groove, the insulator is fixed on the conductor and is fixed on an insulation shielding cylinder through the insulation shielding cylinder fixing bolt hole. The insulator casting body of the utility model is hard, has high mechanical strength and high voltage resistance level, is smooth in surface and small in partial discharge and can be well sealed with GIS equipment, thus avoiding leakage of SF6 in the GIS equipment.
Description
Technical field
The utility model relates to a kind of pipe bus GIS terminals that carry out tube connector for insulate contact tube bus and GIS equipment.
Background technology
Present domestic insulated tube bus is widely used in connecting between electric power system electric equipment, facility, but can't realize docking with the GIS arrangement terminal.The GIS terminal, namely to insert totally-enclosed transformer station be a kind of indoor terminal that is widely used in terminal to cable.Therefore it is necessary to design a kind of pipe bus GIS terminals.
Summary of the invention
The purpose of this utility model is at above-mentioned present situation, aims to provide that a kind of connection is reliable, sealing ensures, insulation property are reliable, can guarantee to manage the bus operation, good looking appearance, fitting operation manage bus GIS terminals easily.
The implementation of the utility model purpose is, pipe bus GIS terminals, there are GIS connector, pipe bus connector in the conductor two ends, the middle outer insulator that is cast with has outer lug boss, outer lug boss that fixing threaded hole, seal groove are arranged in the middle of the insulator, the ring flange outer rim has insulation shielding tube fixing threaded hole, ring flange is fixed on the outer lug boss by fixing threaded hole, and insulator is cast in the holddown groove of conductor into, and insulator is fixed on the conductor.
The utility model utilizes the conductor conduction, the insulator insulation, and ring flange and fixed bolt hole seal groove seal, and insulator is fixed on the conductor, is fixed on the insulation shielding tube by insulation shielding tube fixing threaded hole.Insulator casting matrix of the present utility model is hard, and very high mechanical strength is arranged, the withstand voltage level height, and any surface finish, partial discharge is little, can seal with GIS equipment well, has kept away to exempt from that SF6 leaks in the GIS equipment.
Description of drawings
Accompanying drawing is the utility model structural representation.
Embodiment
With reference to accompanying drawing, there are GIS connector 3, pipe bus connector 2 in conductor 1 two ends, the middle outer insulator 5 that is cast with, outer lug boss is arranged in the middle of the insulator, outer lug boss has fixing threaded hole 8, seal groove 6, and the ring flange outer rim has insulation shielding tube fixing threaded hole 9, and ring flange 7 is fixed on the outer lug boss by fixing threaded hole 8, insulator is cast in the holddown groove 4 of conductor into, and insulator is fixed on the conductor.
The utility model utilizes conductor 1 conduction, insulator 5 insulation, and ring flange and fixed bolt hole seal groove seal, and insulator is fixed on the conductor, is fixed on the insulation shielding tube by insulation shielding tube fixing threaded hole.Insulator casting matrix of the present utility model is hard, and very high mechanical strength is arranged, the withstand voltage level height, and any surface finish, partial discharge is little, can seal with GIS equipment well, has kept away to exempt from that SF6 leaks in the GIS equipment.
