Description
Technical field
The present invention relates to insulation subdomains, more specifically to a kind of electric insulator.
Background technique
Insulator is mounted between the conductor or conductor and earthing component of different potentials and is resistant to voltage and machinery
The device of stress.Insulator is made of insulating part and connection gold utensil (steel cap and steel feet) two large divisions.
Insulator is a kind of special insulation control, can be played an important role in overhead transmission lines.Between one's early years absolutely
Edge is chiefly used in electric pole, and the one end for being slowly developed in high type high-tension bus-bar connection tower has hung the insulator of many plate-likes, it
Effect is to increase creepage distance.At present in all kinds of insulators, porcelain insulator is most commonly used.
The insulating part of porcelain insulator is made of electrotechnical ceramics.Electrotechnical ceramics by quartz, feldspar and clay do raw material bake and
At.The porcelain piece surface of porcelain insulator is usually covered with enamel, and to improve its mechanical strength, waterproof infiltration increases surface flatness.
After electric arc is burnt, surface glaze layer peels off porcelain insulator, and the porcelain body of exposing is easy contamination, leads to decreasing insulating, porcelain is exhausted
" self-destruction " function of the not no glass insulator of edge, therefore power department needs periodically using special detection instrument to porcelain insulating
Son carries out zero value detection.But the case where being easy to appear erroneous judgement and missing inspection during zero value detection, once porcelain insulator loses absolutely
Edge function is easy to bring hidden danger to line security without being found, and influences the power supply of entire power grid, damages making for whole route
With and service life.
Summary of the invention
1. technical problems to be solved
Aiming at the problems existing in the prior art, the purpose of the present invention is to provide a kind of electric insulators, it can be real
