Existing Withstand test device comprises the bushing of vertical setting and is laterally connected in the frock test tube of bushing bottom one side, in bushing, be provided with the high pressure introducing device, in the test tube, be provided with the high-pressure conductor that links to each other with the high pressure introducing device, in the test tube, be full of SF6 gas, be provided with the insulating basin that is used to support high-pressure conductor at high-pressure conductor and high pressure introducing device junction around high-pressure conductor.During test, at the output terminal connection test specimen of high-pressure conductor, the other end of test specimen is connected with earth terminal, strengthens voltage gradually, finishes the insulator withstand voltage test.
In above-mentioned test unit, because high-pressure conductor will lean on insulating basin to support, its syndeton is one-sided cantilever structure, thereby causes passive insulating basin to be subjected to moment of flexure bigger, has influenced the serviceable life of insulating basin, has influenced test findings.And in above-mentioned test unit, the insulator negligible amounts that can once check, test efficiency is lower.And when test, when test specimen integral body was heavier, it was inner to need to use crane that it is sent into the test tube, crane is withdrawed from again, the extra like this potential safety hazard that increases the test assembling.
Summary of the invention
The purpose of this utility model provides a kind of 800KV grade GIS with resistance core bar Withstand test device, then can in Withstand test device can solve the insulating basin that being used in the test tube support high-pressure conductor preferably and bear the bigger technical matters of moment of flexure.
The technical solution of the utility model is: 800KV grade GIS resistance core bar Withstand test device, comprise underframe, be installed with bushing and test frock tube on the underframe, be provided with the high pressure introducing device in the described bushing, be provided with the high-pressure conductor that links to each other with the high pressure introducing device in the described test frock tube, between high-pressure conductor and described high pressure introducing device, be provided with the insulating basin that is used to support high-pressure conductor, downside at described high-pressure conductor is provided with the insulation support, and the lower end of supporting in this insulation is provided with the ground electrode that is installed in described test frock tube inside.
The input end of described high-pressure conductor links to each other with described high pressure introducing device, and the output terminal of described high-pressure conductor is provided with porous and inserts dish, peripheral week upwards is provided with the high-tension shielding ring what described porous was inserted dish.
Described test frock tube inside is provided with the inner tracks that is used to transport test specimen in described ground electrode both sides, on described underframe, be provided with external orbital, externally track is provided with and is used for docking the moving track car with described inner tracks, be provided with on the moving track car can be on the moving track car and test frock tube in inner tracks on the test specimen bracing or strutting arrangement that slides, this bracing or strutting arrangement is provided with the tail electrode of ground connection.
Described test frock tube is the tank body that outer end opening is provided with airtight capping, is provided with safety valve on described tank body.
The beneficial effects of the utility model are: support the inner suffered bigger problem of moment of flexure of insulating basin of frock test tube in the prior art that can solve in the insulation of the downside setting of high-pressure conductor, and the utility model is simple in structure, and economic and practical.And in the utility model, coupling capacitance when utilizing ground capacitance that bushing and turriform wound packages join as measurement of partial discharge, need not be the more extra medium-sized coupling condenser of access set has so just been simplified the test loop, has also reduced the needs of testing transformer capacity.
Porous is set on the output terminal of high-pressure conductor inserts dish, and the high-tension shielding ring circumferentially is set in the periphery of the slotting dish of porous, can be under the premise that security is guaranteed, increase can be checked the quantity of resistance core bar, improves checkability.
Finish the assembling of test specimen in advance on the test specimen bracing or strutting arrangement, and then it is inner by the moving track car test specimen and bracing or strutting arrangement to be pushed frock test tube, bracing or strutting arrangement need not to withdraw from, and use that like this can less crane improves the security of test assembling.
Test frock tube is arranged to the tank body that openend has airtight capping, can improves the efficient of its body of SF6 that vacuumizes, charges and discharge, waves in tank interior, the security performance that safety valve can improve the whole test device is set on tank body.
