The technical scheme adopted that the utility model solves its technical matters is:
A kind of test apparatus for overpressure resistance of insulator spindle, it comprises mounting platform, expansion bracket and grading ring, one end of described expansion bracket is fixed on mounting platform, the other end is fixedly connected with grading ring and supports grading ring, described grading ring is provided with multiple hook, and mounting platform is provided with links up with earthing position one to one with each on grading ring.
Among one embodiment: described mounting platform is equipped with the roller that can realize this device movement.
Among one embodiment: described hook is arranged along ring uniform intervals on grading ring.
Among one embodiment: described expansion bracket comprises interior bar and outer bar, within the sliding bar outside of interior bar, the affixed grading ring in top of interior bar, by regulating the flexible height regulating grading ring of interior bar.
Among one embodiment: described interior bar and outer bar are respectively equipped with pilot hole and elastic, fix the adjustment of grading ring highly by the cooperation of this elastic and pilot hole.
Among one embodiment: described interior bar and outer bar are all provided with pilot hole respectively, and are provided with register pin, fix the adjustment of grading ring highly by the cooperation of this register pin and pilot hole.
Among one embodiment: described earthing position is provided with grounding hook.
Among one embodiment: described earthing position is provided with ground connection groove, and the diameter of the adaptive insulating bar of the diameter of ground connection groove.
The technical program is compared with background technology, and its tool has the following advantages:
1, grading ring is provided with multiple hook, mounting platform is provided with and the plurality of hook grounding hook or ground connection groove one to one, at the trial, one end of insulating bar is connected with the hook on grading ring, the other end is connected with the grounding hook of earthing position or connects with being placed in ground connection ground connection groove, can realize the withstand voltage test of many insulating bars simultaneously; Test efficiency is high, easy to operate.
2, described grading ring connects support by expansion bracket, is regulated carry out withstand voltage test on the apparatus with the insulating bar adapting to different length by the height regulating expansion bracket can realize grading ring.
3, the roller that this device can be made to realize movement is housed, mobility strong below described mounting platform.
When 4, installing or removing insulating bar, only need operate register pin and expansion bracket, grading ring be promoted or declines and can carry out the mounting or dismounting of insulating bar, easy to operate.
5, this test apparatus for overpressure resistance of insulator spindle also has the simple advantage of structure.
