Abstract

The invention relates to a method for installing 500kV compact transmission line phase-to-phase spacers. The method comprises the following steps: sequentially numbering adjacent towers; and installing phase-to-phase spacers on phase conductors according to the distance L between the adjacent towers, the local maximum icing thickness D and the local maximum wind speed V, wherein the icing thickness D is smaller than or equal to 10mm, the maximum wind speed V is smaller than or equal to 15m / s, the distance L is below 600m, or is greater than 600m and smaller than or equal to 800m, or is greater than 800m and smaller than 1000m, and the number of the phase-to-phase spacers arranged on the phase conductors between the adjacent towers is at least 3, 9 or 12. The method of the invention prevents the galloping of 500kV compact transmission lines, and provides technical support for the safe and stable operation of the power grid.

Description

[0001] Technical field:

[0002] The invention relates to a method for installing interphase spacers, and more particularly to a method for installing interphase spacers for 500kV compact power transmission lines.

[0003] Background technique:

[0004] With the rapid development of my country's social economy, the demand for electricity presents a trend of rapid growth. From the perspective of power grid construction and power grid planning, due to the increasing number of transmission lines, in many areas, the tension of power transmission line corridors may become the main factor affecting power grid construction. Compared with conventional power transmission technology, compact power transmission technology has the characteristics of reducing power transmission costs and reducing the land occupation of power transmission corridors. One of the methods. Compared with conventional lines, the phase-to-phase distance of compact transmission lines becomes smaller. However, unde...
