Description

Suspension type porcelain composite insulator

Technical Field

The utility model relates to the technical field of insulator equipment, in particular to a suspension type porcelain composite insulator.

Background

The suspension porcelain composite insulator is used as an important component of an electric power system, and plays an important role in supporting electric power equipment and electrically insulating in alternating current and direct current transmission lines. Insulators operating outdoors are constantly affected by various sources of pollution in the atmosphere. When the air humidity is low, the dirt layer covered on the surface of the insulator does not show conductivity, and the insulator can reliably and safely operate. When the air humidity is high, soluble salt contained in dirt is dissolved in water to form conductive ions, leakage current is formed under the action of working voltage and flows through the surface of an insulator, and a plurality of dry areas are formed on the surface of the insulator due to the heat effect of the current. The resistance of the dry area is far greater than that of the wet area, and the dry area bears higher voltage, so that the local electric field is distorted to generate electric arcs, and even the electric arcs are developed into flashover penetrating through two poles under certain conditions.

The suspension type porcelain composite insulator that uses at present needs the workman through the mode of kinking repeatedly usually in the actual installation, improves the firm degree of insulator, has improved workman's time at high altitude construction like this, if the kinking mode goes wrong simultaneously, the condition that the insulator drops can appear to cause local electric field voltage to be out of balance.
