Abstract
The invention discloses a connecting structure of a geographic information system (GIS) testing device, which comprises a testing device body. A first connecting rod and a second connecting rod which are connected with each other are arranged in the testing device body, the first connecting rod and the second connecting rod adopt a bushing structure, and the first connecting rod is connected with the second connecting rod through a spring contact. The connecting structure of the GIS testing device is simple and convenient to install and dismantle, meets requirements of short-circuit current of a GIS combined electrical apparatus, has excellent electrical contact performance, adopts the beryllium bronze spring contact, and utilizes pressure and durable elasticity of the spring contact to contact. Excellent electric conduction characteristics solve the problem that large current conduction avoids heating in operation.
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.
Summary of the invention
Technical matters to be solved by this invention provides a kind of satisfied 1000mm of surpassing
2The test unit of electric cable with large cross-section GIS terminal testing requirements.
A kind of GIS test unit syndeton of the present invention; 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 improvement of the present invention, 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.
Beneficial effect of the present invention:
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 a structural representation of the present invention.
Embodiment
As shown in Figure 2; GIS test unit syndeton of the present invention; 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 invention solves 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, 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 a preferred implementation of the present invention, should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention, can also make some improvement, and these improvement also should be regarded as protection scope of the present invention.
