Abstract

The embodiments of the invention provide an assembly comprising a supporting insulator and equalizing rings, relates to the field of power systems, and solves the problem that the electric field distribution of the high-voltage end of the existing supporting insulator is non-uniform. The assembly comprising a supporting insulator and equalizing rings comprises the supporting insulator, the supporting insulator comprises an upper supporting insulator section and a lower supporting insulator section connected via a first link fitting in the length direction of the supporting insulator, a runway-type upper equalizing ring and a runway-type lower equalizing ring are arranged at the top of the upper supporting insulator section, and a circular upper equalizing ring and a circular lower equalizing ring are arranged at the joint of the upper supporting insulator section and the lower supporting insulator section and respectively arranged on the upper side and the lower side of the first linkfitting.

Description

technical field [0001] The invention relates to the field of power systems, in particular to an assembly comprising a post insulator and a voltage equalizing ring. Background technique [0002] my country's electric energy is dominated by thermal power and hydropower, and the energy distribution is mainly concentrated in the large-scale hydropower and thermal power bases in the northwest and southwest regions, and the load centers are mainly concentrated in the eastern coastal areas. With the sustained, healthy and stable development of the national economy, the imbalance between energy and load distribution will further intensify. Therefore, the development of high-voltage, long-distance, and large-capacity transmission methods has become a basic strategy and an inevitable choice for my country's energy and power industry construction. [0003] High-voltage direct current transmission has been flourishing in our country because it can transmit a large amount of electric en...
