Portable hydrophobicity testing device for transformer substation

Abstract

The invention discloses a portable hydrophobicity test device for a transformer substation. The portable hydrophobicity test device comprises a bottom telescopic bracket, top water spraying equipmentand a camera device, wherein the bottom telescopic bracket comprises a circular base; an internal thread sleeve is arranged in the middle of the upper surface of the circular base; the inner side surface of the internal thread sleeve is sleeved with a first adjustable telescopic rod; the portable hydrophobicity test device is compact in structure, portable and simple in manipulation, and hydrophobicity tests can be effectively carried out on equipment porcelain bottles with different diameters; meanwhile, climbing operation of an operator can be avoided; the porcelain bottle of the equipment can be positioned through an ultra-wide-angle camera; the whole experiment process can be observed through a microspur camera, the camera device can be rotated and adjusted through a first micro motor,the microspur camera can have a good observation angle, and a test platform can be adjusted to ascend and descend through the arrangement of the first adjustable telescopic rod and a second adjustable telescopic rod.

Description

technical field [0001] The invention relates to the technical field of maintenance equipment for substation electric lines, in particular to a portable substation hydrophobicity test device. Background technique [0002] The equipment vase is used to support and fix the busbar and the live conductor, and to make enough distance and insulation between the live conductors or between the conductor and the earth. Due to the special shed structure of the equipment vase and long-term exposure to the air, the suspended solids in the air , Liquid or gas particles are deposited on the surface of the equipment porcelain bottle to form a dirty layer, which affects the insulation performance of the equipment porcelain bottle and causes pollution flashover. [0003] Composite equipment vases are vulcanized silicone rubber coatings on the outer surface of the equipment vase layer. The excellent anti-pollution flashover performance of composite equipment vases comes from the good hydrophob...

Problems solved by technology

[0004] During actual use, due to factors such as pollution, moisture, and discharge, the hydrophobic performance of the silicone rubber coating on the surface of electrical equipment in operation will decrease or even The loss of hydrophobicity will even directly affect the anti-pollution flashover performance of power transmission and transformation equipment, thus threatening the safe operation of the system. This requires operators to regularly test the hydrophobicity of the silicone rubber coating on the porcelain bottle of the equipment. The existing detection methods For the operator to ascend the height and close range to spray water on each equipment porcelain bottle on the equipment porcelain bottle one by one. The process is as follows: first, the water spray device needs to be fixed on the equipment porcelain bottle, and after detecting the position of one equipment porcelain bottle, it is manually disassembled The water spray device is installed to the next detection point; this method has the disadvantages of heavy workload and heavy operation, and for equipment porcelain bottles with different diameters, it is necessary to select corresponding water spray fixtures, which is inconvenient to carry. Safety cannot be guaranteed
