The invention belongs to the technical field of electric power testing equipment, and particularly discloses a device for testing reliability of the disconnecting force of an insulator, the device comprises a support assembly, a clamping assembly and a force transmission assembly, the clamping assembly is fixed on the support assembly, the clamping assembly comprises an elastic sleeve, the force transmission assembly comprises a force transmission pressing block, a staple bolt, a pull rope and a weight, and the force transmission pressing block is disc-shaped. A through hole is formed in the middle of the force transmission pressing block, the hole diameter of the through hole is smaller than the outer diameter of the flange and larger than the outer diameter of an insulating ring, two clamping nails are symmetrically installed on the force transmission pressing block, the two ends of the pull rope are fixed to the different clamping nails respectively, and the weight is hung on the pull rope through the hook. According to the scheme, a stable set force can be applied to the insulator in a hoisting mode and mainly acts on the end face of the flange, an insulating ring in the insulator cannot be extruded, and problems that in an existing testing method, the testing result is affected by unstable pressure, and a pressing head can generate secondary pollution and damage to the insulating ring are solved.
Description
technical field [0001] The invention belongs to the technical field of electric power testing equipment, and in particular relates to a reliability testing equipment for the disengagement force of an insulator. Background technique [0002] Insulators (Insulation Receptacle), Combined figure 1 As shown, the insulation is realized by dispensing glue in space between the insulating ring and the flange. The existing method of testing the tight fit between the insulating ring and the flange is: use the base to position the flange, and use the indenter to touch the flange. Hold the flange and squeeze the insulating ring, use a manual press to apply a certain force to the insulating ring for 10 seconds, and observe whether there is any displacement between the insulating ring and the flange. [0003] Although this method is simple to operate, there are the following problems. 1. The existing test method needs to continue to apply force to the product manually. During the process ...
