Problems solved by technology

[0003] Conductor spacer is one of the necessary power fittings for transmission lines. At present, the domestically developed ±800 kV high-voltage DC transmission conductor spacers are all single-frame type (the center is supported by an aluminum alloy frame), and their safety factor is low. Corona effect and poor interchangeability of wires of the same type
[0004] Due to the harsh operating environment of ±800 kV HVDC transmission and the large potential gradient, the existing conductive spacers are difficult to meet the requirements of ±800 kV HVDC transmission, so it is necessary to develop new conductive spacers

Abstract

The invention relates to transmission circuit fix wares and to one six crack isolation bar of+-800KV, which comprises central frame and six wire clamper round center, wherein, the wire clamper main part and pressure cover are hinged on front end; the wire clamper main part and pressure cover are set with rubber tilt, wherein, the central rack is composed of two symmetric frames; two frame inner side is set with arc resistance rubber; the clamper back end is between two rubber through bolt, bolt top and close bolt and central frame.

Description

Technical field: [0001] The invention relates to a fitting for installing a power transmission line, in particular to a conductive spacer bar for a high-voltage direct current transmission line. Background technique: [0002] At present, the highest voltage level of DC transmission in the world is ±600 kV. In 2010, China Southern Power Grid will build the world's first ±800 kV HVDC transmission project. Yunguang DC will not only be a new milestone in my country's electric power development, but also create a new chapter in the development of the electric power industry in the world. The Yunguang ±800 kV DC transmission project is the implementation of the UHV transmission network planning plan of the China Southern Power Grid in the "Eleventh Five-Year Plan" and is the main transmission channel for the "Eleventh Five-Year Plan" of the China Southern Power Grid to send electricity from Yun to Guangdong. [0003] Conductor spacer is one of the necessary power fittings for tra...
