Abstract

The invention discloses a test platform capable of achieving wire and ground wire combined DC-based deicing. The test platform comprises a DC output power supply, a DC output parallel-connection first disconnecting link, a DC output parallel-connection second disconnecting link, a DC output positive electrode bus, a DC output negative electrode bus, an A-phase wire first deicing disconnecting link, an A-phase wire second deicing disconnecting link, a B-phase wire first deicing disconnecting link, a B-phase wire second deicing disconnecting link, a C-phase wire first deicing disconnecting link, a C-phase wire second deicing disconnecting link, a first insulating ground wire deicing disconnecting link and a second insulating ground wire deicing disconnecting link. By means of the test platform, the wiring mode can be flexibly adjusted, the requirement for various types of deicing of wires or ground wires during actual line deicing are met, and support is provided for the research on transmission line deicing.

Description

technical field [0001] The invention belongs to the technical field of electrical engineering, and in particular relates to a test platform capable of realizing combined direct current melting of conductors and ground wires, and the platform is suitable for the test of melting ice of conductors and ground wires of power transmission lines. Background technique [0002] Ice and snow disasters occur frequently in some provinces in southern my country, which poses a serious threat to the safety of power grid transmission lines. The implementation of current melting ice on ice-covered lines is one of the most direct, effective, safest and most economical means for power grids to deal with ice disasters. The use of DC ice melting does not need to provide reactive current for the reactive component of the line, which can greatly improve the efficiency and economy of ice melting. Therefore, DC ice melting has been widely used in anti-icing of transmission lines. [0003] At presen...
