Abstract

The invention discloses an insulation column for power equipment. The insulation column for the power equipment comprises a ceramic insulator. The two ends of the ceramic insulator are respectively provided with a threaded hole. The ceramic insulator comprises an insulator body (1) and an insulation umbrella (2) arranged on the insulator body (1). The inclination angle (a) of the umbrella skirt of the insulation umbrella (2) ranges from 12 degrees to 15 degrees. The thickness (h) of the root of the umbrella skirt ranges from 8 mm to 10 mm. The outer surface of the ceramic insulator is coated with a layer of insulating paint. The insulation column for the power equipment can prevent the creepage phenomenon.

Description

technical field [0001] The invention relates to an insulating column for electric equipment. Background technique [0002] The insulating column is a special component that provides the use requirements, installation methods and surrounding application environment requirements for related equipment in the fields of communication cabinets, electric power, lightning protection, machinery, medical treatment, wind energy, and frequency conversion equipment. It mainly functions as fixed support, connection and insulation. The role of insulators, also known as insulators, insulating spacers. Creepage phenomenon refers to the slight discharge phenomenon on the surface of the insulator between the two stages, causing the surface of the insulator (generally) to appear as branches or meridian-like discharge traces of leaves. The current insulating columns have poor creepage prevention effect, and are prone to creepage and pollution flashover accidents. Contents of the invention ...
