Abstract
The utility model discloses a connecting structure of a GIS (gas insulated switchgear) test device. The connecting structure comprises a test device body, wherein a first connecting bar and a second connecting bar which are mutually connected are arranged in the test device body, an embedding sheathing structure is adopted between the first connecting bar and the second connecting bar, and the first connecting bar and the second connecting bar are connected through a spring trigger. The connecting structure has the advantages that the mounting and the dismounting are simple and convenient, the short circuit current requirement of a GIS combined electric appliance is met, the excellent electric contact performance is realized, the beryllium bronze spring trigger is adopted, the contact is realized through the durable elastic force and the pressure of the spring trigger, through the excellent electric conducting performance, the high current conduction problem is solved, and the heating in the operation is avoided.
Description
Technical field
The present invention relates to the cables manufacturing technical field, specifically is a kind of GIS (Gas Insulated Switchgear, Cubicle Gas-Insulated Switchgear) test unit.
Background technology
With GIS inside cable terminal, be used for 110kv crosslinked cable and SF according to the 110KV crosslinked cable of GB11017-2007 standard development
6The connection of gas-insulated metal enclosed switchgear device.Along with process is built in urbanization, high-power equipment for power transmission and distribution is widely applied, and surpasses 1000mm
2The 110kv twisted polyethylene cable in cross section is widely applied.According to IEC502 and GB 11017-2002; Original connected mode of the conventional test device that makes an experiment is because test current can reach 2094A; Big electric current produces a large amount of heats; Cause the intensification of test unit, and then cause the dielectric strength decline of the insulating medium that is connected with test unit and become the main cause that puncture takes place, had a strong impact on the test of this series products.Former connected mode is seen Fig. 1, and two pitmans are to adopt stainless steel bolt to connect in this type of test unit, because the compaction forces of pitman surface of contact influences the conductive resistance between the surface of contact, can satisfy the conduction requirement under the little situation of electric current.Actual conditions have verified that also this device can satisfy 1000mm
2The testing requirements at following GIS terminal.But can not satisfy above 1000mm
2Electric cable with large cross-section GIS terminal testing requirements, it is big that main cause is that bolted contact rod connects the not enough resistance of pressure.
The utility model content
The utility model technical matters to be solved provides a kind of satisfied 1000mm of surpassing
2The test unit of electric cable with large cross-section GIS terminal testing requirements.
The described a kind of GIS test unit syndeton of the utility model; Comprise the test unit body; In the experimental provision body, be provided with interconnective first pitman and second pitman, adopt structure of mosaic between said first pitman and second pitman, touch son through spring between the two and connect.
As the improvement of the utility model, said first pitman is provided with circular groove along axis, and second pitman is provided with the socket cap with the circular groove coupling, and socket cap stretches in the circular groove, and spring touches son along the setting of socket cap outer rim.
The beneficial effect of the utility model:
1) installing/dismounting is simple and convenient.
2) satisfy the requirement of GIS combined electrical apparatus short-circuit current.
3) has good electrical contact performance.
4) adopt the beryllium-bronze spring to touch son, the pressure that utilizes spring to touch son contacts with lasting elastic force; Good conductive characteristic has solved big current lead-through and has avoided operating heating.
Description of drawings
Fig. 1 is the prior art constructions synoptic diagram,
Fig. 2 is the structural representation of the utility model.
Embodiment
As shown in Figure 2; The GIS test unit syndeton of the utility model; Comprise the test unit body; In the experimental provision body, be provided with interconnective first pitman 1 and second pitman 2, adopt structure of mosaic between this first pitman 1 and second pitman 2, touch son 3 through spring between the two and connect.Best structure of mosaic form is: first pitman 1 is provided with circular groove along axis, and second pitman 2 is provided with the socket cap with the circular groove coupling, and socket cap stretches in the circular groove, and spring touches son 3 along the setting of socket cap outer rim.
The utility model has solved the testing requirements of the big electric current of electric cable with large cross-section, and can increase spring and touch the testing requirements that quantum count satisfies different electric cable with large cross-section, and the demand of electric cable with large cross-section test current will have had effective ways to running into more from now on, like 2500mm
2Cable.
The above only is the preferred implementation of the utility model; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; Can also make some improvement, these improve the protection domain that also should be regarded as the utility model.
