Method for strengthening insulation of 10kV overhead line and improving operation reliability

Abstract

The invention relates to a method for strengthening insulation of a 10kV overhead line and improving operation reliability, and belongs to the technical field of distribution network maintenance. In order to salve the problems of bird damages and foreign body damages of the overhead line, the method provided by the invention comprises the following steps: treating conducting wires at two sides of a post tower and the conducting wires passing through a leading wire part; bind the conducting wires and an insulator at the top of a straight line pole insulator by adopting aluminum wire, and directly coating the top end of the insulator, a binding wire and leading wire sleeve ends at two sides together by adopting a prefabricated insulating protecting cover with a corresponding model to ensure that electrified parts are not exposed; and for a tension-resistant pole connecting fitting, uniformly winding the lower end of a suspension insulator and a socket clevis by adopting a silicon rubber hot-melt adhesive tape, and then coating end parts of a tension-resistant wire clip and a conducting wire sleeve together by adopting a prefabricated tension-resistant wire clip insulating protection cover with a corresponding model so as to ensure that the electrified parts are not exposed. The method provided by the invention is wide in application range, convenient in construction, strong in operability, obvious in effect and low in cost.

Description

technical field [0001] The invention relates to a method for strengthening the insulation of overhead lines and improving operation reliability, which is widely used in 10kV overhead lines and belongs to the technical field of distribution network maintenance. Background technique [0002] In recent years, with the rapid expansion of cities, reinforced concrete has seriously encroached on the habitat of birds, forcing birds to build bird nests on power poles and towers. Moreover, a large number of iron wires are mixed in the bird nests. weather, it is easy to cause grounding or short circuit fault. In addition, in fruit growing areas such as the Jiaodong Peninsula, fruit farmers use a lot of reflective film and reflective color strips. In autumn, there are frequent windy weather, and the discarded reflective film and other floating objects are easily scraped off on the wires, causing grounding or short circuit faults. For distribution lines with small interphase distances, ...

In addition, in fruit growing areas such as Jiaodong Peninsula, fruit farmers use a lot of reflective film and reflective color strips. In autumn, windy weather often occurs, and discarded reflective film and other floating objects are easily scraped off on the wires, causing grounding or short circuit faults.
