Abstract

The invention provides a method for distributing an anti-bird device of a direct-current power transmission line tower in a high-altitude area. The method includes the following steps that bird excrement is sprayed to different positions of the lower portion of a cross arm of the power transmission line tower for bird excrement flashover testing, and an area with the flashover phenomenon is determined as a flashover area; the anti-bird device is installed on the portion, above the flashover area, of the power transmission line tower. The flashover area, where the flashover phenomenon is likely to happen, on the lower portion of the cross arm can be accurately determined, and then the anti-bird device is installed on the portion, above the flashover area, of the power transmission line tower, so the anti-bird device is installed more reasonably, the situation that the anti-bird device is installed in an area where the flashover phenomenon is not likely to happen and accordingly installation waste of the anti-bird device is caused is avoided, the number of installed anti-bird devices is effectively reduced, the installation cost of the anti-bird device is greatly reduced, the occurrence frequency of power transmission line flashover accidents caused by bird excrement can be effectively reduced, and safe operation of the power transmission line is ensured.

Description

technical field [0001] The invention relates to the technical field of power transmission systems, in particular to a method for arranging bird-proof devices for DC transmission line poles and towers in high-altitude areas. Background technique [0002] In high-altitude areas, such as Qinghai and Tibet, the vegetation along the transmission line is well protected, and bird activities are frequent. Birds often rest and build nests on transmission line towers. When larger birds excrete feces on transmission line towers, their feces often form a slender guano channel with good conductivity. In the process of falling down, the air gap distance between the transmission wire or the equalizing ring and the tower will be shortened. Under certain conditions, the transmission wire will discharge to the tower, causing a line trip accident. This phenomenon is called guano flashover Accidents, guano flashover accidents seriously threaten the safe and stable operation of the power grid. ...
