Heavy ice area dual-loop co-column suspension type power transmission iron tower

Abstract

The invention discloses a heavy ice area double-loop overhanging type iron tower. The iron tower comprises three layers of crossarms which are a groundwire crossarm (3), an upper lead crossarm (4) and a lower lead crossarm (5) in turn from up to down; the three layers of crossarms are symmetrically arranged at the two sides of a tower body and are arranged on the same vertical surface; the leads of the two loops are respectively arranged at the two sides of the tower body in a Delta shape; the upper lead crossarm is hung on an upper lead (6); the lower lead crossarm is hung on the lower leads (7) and (8). The heavy ice area double-loop overhanging type iron tower has the remarkable advantage of leading the double loops of the same tower to be realized in the heavy ice area. The heavy ice area double-loop overhanging type iron tower has the remarkable advantages of reducing the ice flashover accidents of isolators, retraining the excursion extent of the leads, being beneficial to retraining wind drift and ice covering brandish and shortening the distance between the phase leads for deicing jumping, reducing the upsetting moment loaded by the iron tower, and leading the width of the iron tower and the width of a circuit aisle to be better concerted.

Description

technical field [0001] The invention belongs to a tower structure of power transmission equipment, in particular to a brand-new iron tower structure of double-circuit power transmission lines on the same tower used in heavy ice regions. Background technique [0002] At present, the double-circuit co-tower suspension towers used in my country's transmission lines are all conventional or compact towers in light ice areas and medium ice areas. The existing conventional and compact double-circuit iron towers cannot be applied because the phase conductors are arranged vertically and the distance between the phases is small, and the electrical characteristics such as flashover between the phase conductors of the transmission line in the heavy ice area and the load characteristics of the iron tower in the heavy ice area are not considered. Power transmission lines in heavy ice areas. [0003] As shown in Figure 1, the existing conventional double-circuit iron tower phase conductor...
