Abstract

The invention provides a method for entering a same-tower double-circuit alternating-current transmission line tangent tower equal potential. The method comprises the following steps: an operator arrives at a position parallel to a charged body of a high-voltage alternating-current transmission line through a grounded tangent tower and / or a closest position to the charged body and is at least kept away by a first distance, wherein the first distance refers to the distance between the operator and the charged body; the operator leaves the tangent tower, approaches the charged body and is at least kept away by a second distance, wherein the second distance refers to the sum of the distance between the tangent tower and the operator and the distance between the operator and the charged body; and the operator arrives at the charged body and is kept away by a third distance, wherein the third distance refers to the distance between the operator and the tangent tower. By the adoption of the method of the invention, the problem that operators may easily suffer from an electric shock and be injured in high-voltage and high-altitude environments is solved and the personal safety of operators is ensured.

Description

technical field [0001] The invention relates to the field of safety, in particular to a method for entering the equal potential of a straight tower of a double-circuit AC transmission line on the same tower. Background technique [0002] Qinghai-Tibet AC / DC interconnection project, the AC line starts from Qinghai Riyueshan Substation (2408m above sea level) in the east and ends at Qaidam Converter Station (2878m above sea level) in the west, with a total length of 700km and an altitude of 2680-4000m The average altitude is 3400m; the Qinghai section of Xinjiang and Northwest Main Network AC and Networking Project, Qaidam Converter Station - Yuka Switching Station (3450m above sea level) - Shazhou Substation, the total length of the line in Qinghai is 400km, and the average altitude is above 3200m. The straight pole tower is a horizontal I-type insulator string structure with 6 split conductors. For this special case, its voltage level is determined as 750kV. [0003] Live ...
