Embodiment Construction

[0021] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0022] Referring to FIG. 2 , the bracket for insulating rod withstand voltage test of the present invention includes three parts: an operating cross bar 4 for fixing the tested product, a height-adjustable support rod 5 and an insulating base 6 . The bracket for insulating rod withstand voltage test has two insulating bases 6, two supporting rods 5 are arranged on each insulating base 6, and the upper ends of the two supporting rods 5 on the insulating base 6 on the same side respectively support an operating cross bar 4.

[0023] The operating cross bar 4 is made of composite insulating material and is a guillotine-like structure with a groove, with an overall length of 1200 mm, a width of 80 mm, and a height of 160 mm. A plurality of circular clamping slots 7 with a diameter of 80 mm are evenly arranged on the operating crossbar 4, and a set of springs are install...

Abstract

The invention discloses a support for insulating rod withstand voltage testing. The support comprises operation transverse rods, supporting rods and insulating bases, wherein the operation transverse rods are used for fixing an object to be tested, the height of the supporting rods is adjustable, the number of the insulating bases is two, each insulating base is provided with two supporting rods, the upper ends of two supporting rods on the insulating base on the same side are respectively provided with one operation transverse rod in a supported mode, each operation transverse rod is evenly provided with multiple round clamping grooves, the upper portion and the lower portion of the inside of each round clamping groove are respectively provided with one set of springs so as to effectively fix and clamp the object to be tested, an over-current fuse is arranged under each round clamping groove, the two insulating bases are connected through a caliper with scales, each insulating base is provided with two idler wheels, and each idler wheel is provided with a braking device. The support for insulating rod withstand voltage testing meets the requirements of withstand voltage testing of insulating rods at different voltage levels.

Description

technical field [0001] The invention relates to a support for insulating rod withstand voltage tests, in particular to a support capable of meeting the requirements of insulating rod withstand voltage tests of different voltage levels below 220kV. Background technique [0002] Insulating rods are used to directly operate high-voltage isolating switches and drop insurance, install and remove temporary grounding wires, and conduct electrical inspection, measurement or testing of electrical equipment above 35kV. The insulating rod is generally composed of three parts: the working part 1, the insulating part 2 and the handshake part 3. The withstand voltage test voltage of the insulating rod is applied between the working part 1 and the handshake part 3. [0003] The withstand voltage test of insulating rods should ensure the test length, and the corresponding test lengths of insulating rods of different voltage levels are different. In order to improve work efficiency, the AC...
