Description

A suspension type porcelain composite insulator

technical field

The utility model relates to the technical field of insulator equipment, in particular to a suspended ceramic composite insulator.

Background technique

As an important part of the power system, the suspension porcelain composite insulator plays an important role in supporting the power equipment and electrical insulation in the AC and DC transmission lines. Outdoor insulators are always affected by various pollution sources in the atmosphere. When the air humidity is low, the contamination layer covered on the surface of the insulator does not show conductivity, and the insulator can operate reliably and safely. When the air humidity is high, the soluble salt contained in the dirt dissolves in water to form conductive ions, and under the action of the working voltage, a leakage current flows on the surface of the insulator, and the thermal effect of the current leads to the formation of multiple dry areas on the surface of the insulator. The resistance of the dry area is much larger than that of the wet area, and it is subjected to higher voltages, causing local electric field distortions to generate arcs, and even develop into flashovers running through the poles under certain conditions.

The currently used suspension porcelain composite insulators usually require workers to repeatedly wrap the wires to improve the firmness of the insulators during the actual installation process, which increases the time for workers to work at high altitudes. The insulator will fall off, causing the local electric field voltage to be out of balance.
