Description

Technical Field

[0001] The utility model relates to the technical field of electrical equipment, in particular to a live water flushing spray gun for arc-proof electrical equipment. Background Art

[0002] When dirt accumulates on the surface of high-voltage electrical equipment to form a dirt layer, especially in humid weather conditions, the conductive substances in the dirt dissolve in water to form a conductive layer, which will cause the surface insulation resistance to drop significantly and increase the risk of insulator breakdown. Therefore, regular cleaning of the insulator surface is one of the important steps to ensure the safe operation of electrical equipment.

[0003] When washing insulators at high places, most of the time a long-pole spray gun is used for washing. Since the worker holds the spray gun with his wrist in a bent state, a large load is placed on the wrist during long hours of work, which can easily cause wrist strain.

[0004] Therefore, we propose a live water flushing spray gun for arc-proof electric equipment to solve the above-mentioned problems. Utility Model Content
