Abstract

The invention discloses a twelve-bundle conductor spacer, which relates to a bundle conductor spacer, in particular to the twelve-bundle conductor spacer utilized for 1,150KV alternating current compact transmission lines. The spacer comprises a frame and wire clamps, wherein one end of each wire clamp is connected with a gland through a hinge pin; a pin shaft and a split pin are arranged on the wire clamp for fixing the gland; a rubber tile is arranged between the gland and the wire clamp; the external side of the frame is connected with twelve wire clamps through fasteners; and a spacing body and a damping piece are arranged at the end, connected with the frame, of the wire clamp. The spacer has the advantages of high mechanical performance and capacity of meeting requirements of the 1,150KV alternating current transmission lines on electric corona and radio interference.

Description

technical field [0001] The invention relates to a split wire spacer, in particular to a twelve-split wire spacer used for 1150kV AC compact power transmission lines. Background technique [0002] The split conductors of the transmission lines of all voltage levels must use spacers. The main purpose of the spacers is to limit the relative movement between the sub-conductors and maintain the geometry of the split conductors under normal conditions. According to the voltage level of the transmission line and the number of split wires, the currently used wire spacers can be divided into five types for two, three, four, six, and eight split wires. The split conductors of 1000kV AC transmission lines generally use eight-split conductor spacers, which is also the split conductor spacer with the highest number of splits currently used in China. With the emergence of 1150kV AC transmission lines, as a way of 1150kV AC transmission technology, the compact transmission line uses twelv...
