The object of the present invention is achieved like this, design a kind of used for high-voltage switch cable tail bushing insulator, it comprises the cable jockey, bushing insulator, lead-in wire, it is characterized in that: the cable jockey is that to insert a conductive lever crimping by EPT rubber cable be one, and ethylene propylene diene rubber is sulfided into a cone structure, pyramid tip is a cable tail, the bottom is the conductive lever exit with band back tip, the conductive lever exit of the band back tip is socketed with rubber seal and the bushing insulator cavity forms sealing, and the bushing insulator other end is connected with high voltage switch part.
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.
Below in conjunction with the embodiment accompanying drawing the present invention is described further.
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.
Accompanying drawing 5 is embodiment vacuum arc extinguish chamber structure schematic diagrames.
Among the figure: 1, ethylene propylene diene rubber (EPDM) cable; 2, ethylene propylene diene rubber (EPDM) cone; 3, rubber seal; 4, conductive lever; 5, bushing insulator; 6, high voltage switch part.
As shown in Figure 1 and Figure 2, bushing insulator 5 one ends have been inserted the cable jockey, cable jockey wherein is to insert conductive lever 4 both crimping of back by EPT rubber cable 1, and be sulfided into a cone structure with ethylene propylene diene rubber, pyramid tip is the EPT rubber cable lead-in wire, is convenient to connect high-tension line; The bottom is conductive lever 4 exits, and conductive lever 4 exits have rubber seal 3, it and bushing insulator 5 bore seal; Bushing insulator 5 other ends are connected with high voltage switch part.
In Fig. 1,2 embodiment, bushing insulator 5 inner chambers can embedded high voltage switch part such as the vacuum interrupter or the quiet edge of a knife of isolation knife, 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, axial thread connects, form good faying surface, be convenient to install good integrity, improve reliability.And the outer surface of bushing insulator 5 can be with full skirt such as Fig. 1, shown in Figure 3.The bushing insulator 5 of outer surface belt full skirt can increase creepage distance under the situation that does not increase size, stopped the pollution flashover phenomenon.The outer surface of bushing insulator 5 also can be with full skirt such as Fig. 2, shown in Figure 4.The cable jockey glueds joint with the inner chamber of bushing insulator 5 and is connected.It has good seal performance, effectively prevents short circuit, damage that foreign matter overlap joint and toy overlap joint cause.Effectively reducing circuit installs because of connecting the improper sleeve pipe damage that causes.
