Abstract

The invention relates to an enhancement mode flange for a supporting composite insulator. The enhancement mode flange comprises a conical main body (1), wherein a hollow cavity is formed in the conical main body (1), and an inner cavity positioning region (6) is arranged on the lower part of the hollow cavity; the inner cavity positioning region (6) is used for performing guiding when a core rod is inserted into the flange; a core rod putting-in region (7) which is larger than the size of the inner cavity positioning region (6) is arranged on the upper part of the hollow cavity; and the innercavity positioning region (6) and the core rod putting-in region (7) are coaxially arranged. The invention aims to provide the flange for the extra-high voltage supporting composite insulator, and themechanical strength of the insulator can be greatly improved, while damage of moisture to the electrical performance of the insulator can be avoided.

Description

technical field [0001] The invention relates to a reinforced flange for post composite insulators. Background technique [0002] The traditional flange glue-mounted structure of UHV post composite insulators has a large mechanical performance, especially the bending deflection value, which is difficult to meet the requirements of the power system. [0003] The height of the enhanced flange is greatly increased, providing extremely high mechanical properties of the flange, especially the bending resistance, which can effectively solve the problem of large bending resistance offset. [0004] Since the environment of UHV post composite insulators is very different, especially in areas with a lot of precipitation, the moisture is heavy, how to prevent moisture from penetrating into the interior of the insulator is an urgent problem to be solved. Contents of the invention [0005] In view of the deficiencies of the existing flange design technology, the purpose of the present ...
