Description

technical field [0001] The invention belongs to the technical field of maintenance equipment for power transmission and transformation lines, and in particular relates to a water spraying device for composite insulators of overhead lines. Background technique [0002] Insulators are used to support and fix busbars and live conductors, and to provide sufficient distance and insulation between live conductors or between conductors and the ground. Due to the special shed structure of the insulator and long-term exposure to the air, solids and liquids suspended in the air Or gas particles deposit on the surface of the insulator to form a pollution layer, which affects the insulation performance of the insulator and causes pollution flashover. [0003] Composite insulators are vulcanized silicone rubber coatings on the outer surface of the insulator layer. The excellent pollution flashover resistance of composite insulators comes from the good hydrophobicity of the outer insulati...

Problems solved by technology

[0004] In actual use, due to pollution, humidity, discharge and other factors, the hydrophobic performance of the silicone rubber coating on the surface of electrical equipment in operation will decrease or even be lost, and the decrease in hydrophobicity will even directly affect the resistance of power transmission and transformation equipment. Pollution flashover performance, thus threatening the safe operation of the system, requires operators to regularly test the hydrophobicity of the silicone rubber coating of the insulator string. The existing detection method is that the operator climbs up and inspects each insulator on the insulator string The process of water spraying detection one by one is as follows: firstly, the water spraying device needs to be fixed on the insulator string, after one insulator point is detected, and then the water spraying device is manually dismantled and installed to the next detection point; this method has a large workload. , The disadvantage of heavy operation, and for insulator strings of different diameters, it is necessary to select the corresponding water spray fixtures, which is inconvenient to carry. In addition, the safety of working at heights cannot be guaranteed.
