Described high voltage switch part can be a vacuum interrupter, and vacuum interrupter is inserted in the bushing insulator cavity.
Described high voltage switch part can be the quiet edge of a knife of isolation knife, and the quiet edge of a knife of isolation knife is inserted in the bushing insulator cavity.
Described ethylene propylene diene rubber (EPDM) cone cable can adopt to glued joint with bushing insulator and be connected.
Described vacuum interrupter, dynamic and static contact extraction electrode adopts the oxygen-free copper approach screw, and two ends adopt on-plane surface can cut down the sealing-in mode, can embeddedly install, and axial thread connects, and forms good faying surface, is convenient to install good integrity, improves reliability.
Described ethylene propylene diene rubber (EPDM) cable adopts zinc-plated anticorrosion multiply copper core, the liner semiconductor tape, and ethylene propylene diene rubber (EPDM) insulation is adopted on the surface, whole soft pliable song, insulation property are good, and anti-galvanic corrosion is anti-aging.
Described bushing insulator outer surface can be with full skirt.
The back tip of described cable jockey is inserted in the cavity of bushing insulator.
The cone of described cable jockey or the part of cone are inserted in the cavity of bushing insulator together with the back tip.
Advantage of the present invention:
1. can finish the effect such as lead-in wire sealing, insulation, electric energy transmitting, fixed installation of high voltage switchgear.
2. can embedded vacuum interrupter or the quiet edge of a knife of isolation knife and it is played fixing, installation, insulation against ground effect.
3. all-sealed structure, the reliability height has protective capacities, can long-term non-maintaining operation.
4. insulator cable all insulation has increased creepage distance, has stopped the pollution flashover phenomenon.
5. effectively prevent short circuit, damage that foreign matter overlap joint and toy overlap joint cause.
6. ground such as the electric power system of be suitable for that the salt fog density is big, high humidity, dust are serious, factory, mine, oil field, desert, and the low pressure place of height above sea level more than 1,000 meter.
7. the present invention has characteristics such as volume is little, structure refining, the life-span is long, and working stability is reliable, and is non-maintaining.
Description of drawings: the present invention is described further below in conjunction with the embodiment accompanying drawing.
Accompanying drawing 1 is embodiment 1 a structural profile schematic diagram.
Accompanying drawing 2 is embodiment 2 structural profile schematic diagrames.
Accompanying drawing 3 is embodiment 1 bushing insulator structural profile schematic diagrames.
