Abstract
The utility model discloses the non-standard GIS cable terminations of one kind experiment.Three-phase coenosarc structure can produce larger interference for the separate judgement of defective cable, while influence defect location；There has been no the three-phase Split type structure GIS cable terminations of 110kV voltage class at present.The utility model includes 220kV GIS switches warehouse, counter flange and one section of 110kV cable termination, described 220kV GIS switch warehouses are connected by counter flange with the metal shell of 110kV cable terminations, and it is 110kV GIS interfaces that the counter flange, which is used for 220kV GIS interface conversions,.The utility model uses three-phase split-type design, and the high-tension cable for realizing GIS and the 110kV voltage class of 220kV voltage class is connected；Each 220kV GIS switch warehouses only carry out corresponding connection with a 110kV cable termination, are easy to defects simulation experiment to carry out.
Description
Technical field
Hv cable termination field is the utility model is related to, especially a kind of non-standard GIS cable terminations of experiment.
Background technology
With widely using for domestic transformer station's GIS combination electric appliance, increasing substation cable outlet is whole using GIS
End structure.At present, the domestic 220kV used and above GIS cable terminations use three-phase Split type structure, and 110kV
GIS cable terminations use three-phase coenosarc structure.
During 110kV electric cable stoppage simulated experiments are carried out, if GIS cable terminations use three-phase coenosarc structure, it can lead
Defect characteristic signal " string phase " is caused, defect location effect is influenceed, causes result of the test misjudgment.So for 110kV cables
Defects simulation is tested, and its GIS cable termination is very necessary using three-phase Split type structure.
Utility model content
Technical problem to be solved in the utility model is the defects of overcoming above-mentioned prior art to exist, there is provided one kind experiment
With off-gauge 110kV GIS cable terminations, the GIS cable terminations use three-phase split-type structural, are easy to defects simulation to test
Carry out.
Therefore, the utility model adopts the following technical scheme that：One kind experiment non-standard GIS cable terminations, including one
220kV GIS switches warehouse, a counter flange and one section of 110kV cable termination, described 220kV GIS switch warehouses passed through
The metal shell that flange is crossed with 110kV cable terminations is connected, and the counter flange for being by 220kV GIS interface conversions
110kV GIS interfaces, it is ensured that 220kV GIS switch the close connection of warehouse and 110kV cable termination metal shells.
As the supplement of above-mentioned technical proposal, the insulating part of the 110kV cable terminations is integrally inserted in 220kV GIS and opened
In the inside for closing warehouse.
As the supplement of above-mentioned technical proposal, described counter flange by rivet and 220kV GIS switch warehouse and
The metal shell of 110kV cable terminations closely connects.
220kV GIS switch warehouses of the present utility model use three-phase split-type design with 110kV cable terminations, realize
The high-tension cable of GIS and the 110kV voltage class of 220kV voltage class is connected；Each 220kV GIS switch warehouse and one
110kV cable terminations carry out corresponding connection, are easy to defects simulation experiment to carry out.
Brief description of the drawings
Contrasted in order to illustrate more clearly of the technical solution of the utility model, and with the technical scheme of background technology,
The accompanying drawing used required for the utility model embodiment will be briefly described below.It should be evident that below in description
The utility model embodiment accompanying drawing is only part of the embodiment, for those of ordinary skill in the art, is not paying wound
On the premise of the property made is worked, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 shows structural representation of the present utility model.
In figure, 1-220kV GIS switch warehouses, the insulating part of 2-110kV cable terminations, the gold of 3-110kV cable terminations
Belong to shell, 4- counter flanges, 5- cables.
Embodiment
Below in conjunction with accompanying drawing of the present utility model, the technical solution of the utility model is clearly and completely described,
Obviously, described the utility model embodiment is only the utility model part of the embodiment, rather than whole embodiments.
Based on the embodiment in the utility model, what those of ordinary skill in the art were obtained under the premise of creative work is not made
Every other embodiment, belong to the scope of the utility model protection.
GIS cable terminations as shown in Figure 1,220kV GIS switch warehouses 1 pass through counter flange 4 and 110kV cable terminations
Metal shell 3 be connected, the insulating part of 110kV cable terminations 2 is overall to be inserted into inside 220kV GIS switch warehouses 1.
The metal shell 3 that the counter flange 4 switchs warehouse 1 and 110kV cable terminations by rivet with 220kV GIS is tight
Close connection.
