Abstract

The invention relates to the technical field of insulator creepage prevention structures, in particular to an insulator structure capable of preventing a creepage phenomenon based on power equipment.The insulator structure comprises an upper umbrella skirt, the upper umbrella skirt at least comprises a first large umbrella skirt, an upper insulating arc is fixedly connected to the top of the first large umbrella skirt, a first threaded pipe is fixedly connected to the top of the upper insulating arc, a creepage increasing skirt is fixedly installed on the upper surface of a second large umbrella skirt, and a first fixing screw hole is formed in the position, close to the top, of the second large umbrella skirt; through the arrangement of the combined silicone rubber umbrella cover, the length of the silicone rubber umbrella cover can be adjusted, then the creep distance is effectively adjusted, and the creepage phenomenon is relieved by adjusting the creep distance so as to adapt to different use environments and further adapt to a threaded connection mode, the tightness of combination and connection of the silicone rubber umbrella cover is effectively improved, the integrity of the silicone rubber umbrella cover is guaranteed, the insulating core rod is effectively protected, and the insulating core rod is prevented from being affected by weather and being electrically corroded.

Description

technical field [0001] The invention relates to the technical field of an insulator anti-creepage structure, in particular to an insulator structure based on electric equipment that can prevent the creepage phenomenon. Background technique [0002] The cause of the creepage phenomenon is: the surface of the insulating part is contaminated, which reduces the insulation strength of the insulating part, and creepage occurs in humid air. The essence of creepage is that the voltage distribution on the insulating surface is uneven, resulting in partial discharge; the creepage phenomenon is between two poles. There is a slight discharge phenomenon on the surface of the insulator between the insulators, causing the surface of the insulator to be dendritic or meridian-shaped discharge traces of leaves. Generally, such discharge traces are not connected to the two poles. The discharge is generally not continuous, but only occurs under specific conditions, such as Humid weather, dirt a...

[0002] The cause of the creepage phenomenon is: the surface of the insulating part is contaminated, which reduces the insulation strength of the insulating part, and creepage occurs in humid air. The essence of creepage is that the voltage distribution on the insulating surface is uneven, resulting in partial discharge; the creepage phenomenon is between two poles. There is a slight discharge phenomenon on the surface of the insulator between the insulators, causing the surface of the insulator to be dendritic or meridian-like discharge traces of leaves. Generally, such discharge traces are not connected to the two poles. The discharge is generally not continuous, but only occurs under specific conditions, such as Humid weather, dirt, dust, etc. on the surface of the insulator will lead to insulation damage after a long time

[0003] During the power transmission process of power equipment, the creepage phenomenon of insulators is likely to cause damage to the line and cause economic losses. Therefore, the purpose of the present invention is to prevent the creepage phenomenon based on the insulator structure of the power equipment, so as to alleviate the insulator in the power transmission process of the power equipment.
