The test device comprises a cable, a contact, a contact disc, a connection fitting, a shielding case, a casing pipe, a gas tank, and an equalizing ring. The contact is connected with the cable provided with a tested product, the spring contact finger is arranged in the connection fitting in the gas tank, the shielding case is arranged outside the connection fitting, the contact disc is used to connect the connection fitting and the shielding case, one end of the cable which is connected with the contact is inserted into the connection fitting, the electrically-conductive portion of the casing pipe is vertically inserted into the connection fitting in the gas tank, and the equalizing ring is connected and fixed with the high-voltage wire connection terminal of the casing pipe. The product technology of the utility model is applied in the delivery inspection of a gas insulated switchgear (GIS) terminal stress cone of 220kV and above, and a conventional GIS terminal and an outdoor terminal containing insulating filler is replaced with a fixed test device, so the delivery inspection efficiency is improved.
Description
Technical field
The utility model relates to high-pressure test device, relates in particular to 220kV and above cable accessory test unit.
Background technology
Prior art is:
While doing experiment, cable one end adopts the GIS terminal, and the other end can only adopt containing insulation filling agent outdoor terminal in order to connect high-voltage connection.
While doing the test of GIS terminal stress cone, need to will lift with the cable of GIS terminal stress cone with manpower, keep pushing the GIS cylinder after cable and GIS cylinder coaxial.
The GIS end cable is connected employing watchband-shaped contactor (watchband-shaped contactor: the elastic conduction fingertip that shape is beryllium-bronze as watchband, material) contact with the conductor of GIS cylinder.
Problem and the defect of its existence are:
Containing insulation filling agent terminal, install complicatedly, inside also needs a terminal stress cone, when checking out electric discharge, can't determine which in two terminal stress cones has problem, the judgement of impact to the test product test findings.Stress cone containing insulation filling agent inside just needs to change at set intervals in addition, has a strong impact on checkability.
Also can't guarantee coaxially when manpower lifts cable and pushes cylinder, therefore can't one-step installation put in place, advance back and forth with the process of extracting in, likely can cause the test product damage or make the surface contamination dust, affect test findings;
Adopt the connected mode of watchband-shaped contactor contact, due to the friction force of watchband-shaped contactor, complete rear being difficult to of test cable is extracted out from cylinder.
The utility model content
In order to solve problem in prior art, the utility model provides a kind of 220kV and above cable accessory test unit, it comprises cable, contact, contact disc, connect gold utensil, radome, sleeve pipe, gas tank, grading ring, contact is connected with the cable with test product, spring touch finger is arranged in the connection gold utensil in gas tank, radome is arranged on and connects the gold utensil outside, contact disc will connect gold utensil and be connected with radome, the end that cable is connected with contact inserts and connects in gold utensil, the sleeve pipe current-carrying part vertically inserts in the connection gold utensil in gas tank, grading ring and casing high pressure terminals are connected and fixed.
As further improvement of the utility model, contact is connected with the cable with test product by hexagon socket head cap screw.
As further improvement of the utility model, described contact disc is threaded with being connected gold utensil, and contact disc is arranged in radome and will connects gold utensil and be connected with radome.
As further improvement of the utility model, by screw, the flange of cable, cone holder and gas tank are locked.
As further improvement of the utility model, sleeve pipe and gas tank are by screw locking.
The beneficial effects of the utility model are: the utility model product technology is applied to 220kV and the factory inspection of above gas-insulated closed equipment (GIS) terminal stress cone, adopt fixing test unit to replace the traditional GIS terminal and, containing insulation filling agent outdoor terminal, improve factory inspection efficiency.
