Abstract

The invention provides a ground wire direct current-based deicing automatic wiring system, consisting of a direct current-based deicing device (1), a two-transformation three-isolation switch (2), a three-phase bus (3), an outgoing line isolation switch (5) and a wire deicing short-circuit isolation switch (7), wherein the output end of the direct current-based deicing device (1) is connected with the input end of the two-transformation three-isolation switch (2); the output end of the two-transformation three-isolation switch (2) is connected with the three-phase bus (3); the three-phase bus (3) is connected with the outgoing line isolation switch (5); and the outgoing line isolation switch (5) is connected with the wire deicing short-circuit isolation switch (7) in series. The ground wire direct current-based deicing automatic wiring system has the advantages that the switching of wire deicing and ground wire deicing can be rapidly realized, the outage time can be shortened, the deicing efficiency is improved, the safety is improved, the deicing of a plurality of lines can be rapidly realized, guarantee can be provided for the stable operation of a power grid, and the loss caused by freezing disasters is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of electrical engineering and relates to an automatic wiring system for direct current melting of ground wires. The system can automatically operate the connection between the DC ice-melting device and the ice-melting ground wire, and automatically operate the short-circuiting between the ice-melting ground wire and the wire. Background technique [0002] In recent years, the power system has frequently suffered from freezing disasters, and the phenomenon of downed towers and broken lines of transmission lines has been serious, which has brought huge economic losses to the country and seriously affected people's production and life. [0003] The putting into use of the ice-melting device, especially the implementation of the ground wire DC ice-melting method, has completely changed the situation in which the power transmission lines could only passively resist disasters in the face of ice disasters, eased th...
