Abstract
The utility model relates to a shield connection device of a crosslinking cable terminal and a GIS switch housing. The shield connection device comprises an upper installation flange, an insulation sleeve and a lower installation flange, wherein the GIS switch housing is connected with the insulation sleeve through the upper installation flange; and the insulation sleeve is connected with the crosslinking cable terminal through the lower installation flange. Compared with the prior art, the shield connection device has the advantages of high safety, reliability and the like.
Description
Technical field
The utility model relates to a kind of cable termination and GIS switch housing connection device, especially relates to a kind of crosslinked cable terminal and GIS switch housing shielding jockey.
Background technology
For reducing the cable metal sheath induced voltage, the cross interconnected earthing mode of the many employings of ultrahigh voltage power cable metal sheath.Raise for reducing electromagnetic field effects and suppressing the transient state earth potential, the GIS switch adopts continuous type shell (ground connection completely) more on the engineering.If directly connect, GIS switch housing circulation can enter the cable grounding point through the shielding connecting line between both grounding systems.Shell circulation flows into and will cause the loss heating, not only can influence the ampacity of cable, also can accelerate ageing of insulation.
The utility model content
The purpose of this utility model is exactly to provide a kind of crosslinked cable terminal and GIS switch housing safe, good reliability to shield jockey for the defective that overcomes above-mentioned prior art existence.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of crosslinked cable terminal and GIS switch housing shielding jockey, it is characterized in that, comprise mounting flange, insulating sleeve and following mounting flange, described GIS switch housing is connected with insulating sleeve by last mounting flange, and mounting flange was connected with the crosslinked cable terminal under described insulating sleeve passed through.
Described going up between mounting flange and the following mounting flange installed lightning arrester.
Compared with prior art, the utlity model has following advantage:
1, obviously reduced the earth current of cable line outer jacket, the useful life of having improved cable;
2, safe, by the installing lightning arrester, when GIS switch motion or fault, but safeguard work personnel's personal safety and cable machinery are not damaged.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Embodiment
As shown in Figure 1, a kind of crosslinked cable terminal and GIS switch housing shielding jockey, comprise mounting flange 2, insulating sleeve 3 and following mounting flange 4, described GIS switch housing 1 is connected with insulating sleeve 3 by last mounting flange 2, and mounting flange 4 was connected with crosslinked cable terminal 5 under described insulating sleeve 3 passed through.Described going up installed lightning arrester 6 between mounting flange 2 and the following mounting flange 4.
When GIS switch motion or fault, will produce the transient state earth potential at the shell at GIS ground connection place and raise.For safeguard work personnel's personal safety and cable machinery is not damaged, is chosen in the shielding conductor place and installs lightning arrester additional, with over-voltage.
Claims (2)
1. a crosslinked cable terminal and GIS switch housing shielding jockey, it is characterized in that, comprise mounting flange, insulating sleeve and following mounting flange, described GIS switch housing is connected with insulating sleeve by last mounting flange, and mounting flange was connected with the crosslinked cable terminal under described insulating sleeve passed through.
2. a kind of crosslinked cable terminal according to claim 1 and GIS switch housing shielding jockey is characterized in that, described going up between mounting flange and the following mounting flange installed lightning arrester.
