Abstract
A kind of insulation shielding ground short circuit line for switch cubicle flash test, be characterized in: it comprises three insulated cables, three chucks, binding posts, one end of described three insulated cables is electrically connected with three chucks respectively, the other end is electrically connected with binding post simultaneously, three head end insulating cases cover on chuck respectively, styletable insulating case is socketed in electrical connection place of three cables and binding post, and protection insulating case covers on the termination of binding post.During as ground wire, binding post is electrically connected with ground stud, and protection insulating case covers on the termination of binding post, and three chucks clamp three cable electrical connections of three-phase wire respectively, and head end insulating case covers on chuck and electrical connection place.During as high voltage short circuit line, binding post is electrically connected with the lead-out terminal of high-tension apparatus, protection insulating case covers on the termination of binding post, and three cables that three chucks clamp three-phase wire are respectively electrically connected, and cover on chuck respectively and electrical connection place by head end insulating case.
Description
Technical field
The utility model relates to power test instrument, is a kind of insulation shielding ground short circuit line for switch cubicle flash test, to meet the demand of 35kV and following high-tension distribution chamber of converting switch cubicle flash test.
Background technology
Current power system transformer substation institute 35kV and following high-tension distribution chamber of converting switch cubicle many employings compact enclosed construction, and mostly be cable and allot.When carrying out Insulation Test, same spacing devices spacing is little, easily discharges, be unfavorable for that work is carried out, and for the cable allotted and other equipment test voltage phase difference of switch cubicle very large, be not suitable for testing simultaneously, when Insulation Test, non-tested device needs ground connection with guarantee equipment and personal security.Scene, in order to reach test requirements document, will adjust cable position usually, easy to cable formation latent lesion on the contrary in pulling process.Therefore for meeting the needs of high-tension switch cabinet electrical test, a kind of ground short circuit line of tape insulation function of shielding is developed.
Utility model content
Technical problem to be solved in the utility model is: the shortcoming overcoming prior art, being provided for the insulation shielding ground short circuit line of switch cubicle flash test, tested device can being met and non-need not adjustment by testing the required distance of equipment room allots cable position.
The scheme of the utility model technical solution problem is: for the insulation shielding ground short circuit line of switch cubicle flash test, it is characterized in that: it comprises three insulated cables, three chucks, binding post, three head end insulating cases, styletable insulating case and protection insulating case, one end of described three insulated cables is electrically connected with three chucks respectively, the other end is electrically connected with binding post simultaneously, three head end insulating cases to cover on respectively on chuck and are socketed in electrical connection place of chuck and insulated cable, styletable insulating case is socketed in electrical connection place of three cables and binding post, binding post termination is exposed outside styletable insulating case, protection insulating case covers on the termination of binding post.
The beneficial effect that the utility model is used for the insulation shielding ground short circuit line of switch cubicle flash test is, 35kV and following high-tension distribution chamber of converting switch cubicle can be met in flash test, tested device and non-ly to be changed by the distance testing equipment room, allot cable position without the need to adjustment can safe and reliablely test, prevent from adjusting in the pulling process allotting cable distance to the latent lesion that cable is formed.When the utility model uses as ground wire, binding post is electrically connected with the ground stud near cabinet, again protection insulating case is covered on the termination of binding post and electrical connection place of binding post and ground stud, then three cables three chucks being clamped respectively three-phase wire are electrically connected, and cover on chuck respectively by head end insulating case, are socketed in electrical connection place of chuck and insulated cable and can test.When the utility model uses as high voltage short circuit line, binding post is electrically connected with the lead-out terminal of high-tension apparatus, again protection insulating case is covered on the termination of binding post and electrical connection place of binding post and high-tension apparatus lead-out terminal, then three cables three chucks being clamped respectively three-phase wire are electrically connected, and cover on chuck respectively by head end insulating case, are socketed in electrical connection place of chuck and insulated cable and can test.Have that structure is simple, easy to use, with low cost, the advantage of Be very effective.
