Abstract

The invention provides a catenary ice-melting system with self-cycling energy. The system comprises N groups of transformation mechanisms, each group of transformation mechanisms comprises a rectifying unit and an energy feed device, and N is an arbitrary integer greater than or equal to 1; the two sides of each rectifying unit are connected to a medium-voltage ring network and a direct-current catenary respectively, and the two sides of each energy feed device are connected to the medium-voltage ring network and the direct-current catenary respectively; in the first state, the rectifying unit of one transformation mechanism, an ice section to be melt of the direct-current catenary, the energy feed device of another transformation mechanism and a corresponding section of the medium-voltage ring network form an energy cycle, and the current value of the ice section to be melt is not lower than a critical ice-melting current value.

Description

technical field [0001] The invention relates to the field of rail transportation, in particular to an energy self-circulating catenary ice-melting system. Background technique [0002] The catenary is an important part of the traction power supply system of urban rail transit. It is a transmission line suspended along the top of the rail to provide electric energy for the train. Catenary icing refers to the phenomenon that water droplets condense on the contact line after encountering cold air, causing a large area of ​​contact line to be wrapped in ice. [0003] At present, the commonly used ice-melting methods of rail transit catenary include: artificial deicing method, thermal sliding of catenary and chemical agent method. These methods are time-consuming and laborious, and the ice-melting effect is poor. For this reason, in the related art, the method of heating and deicing with built-in resistance wire and the method of thermally melting ice with an external deicing de...
