According to the alternating-current ice-melting electric reactor applicable to the contact net of the high-speed rail disclosed by the invention, operation key feature parameters and technical parameters of a dry type hollow electric reactor are determined according to system features and item requirements of an ice-melting device for the high-speed rail; and the capacity of the alternating-current ice-melting electric reactor applicable to the contact net of the high-speed rail is adjusted by adopting a multi-stage split type capacity adjusting technology.

Description

technical field [0001] The invention relates to a reactor, in particular to an AC ice-melting reactor applied to a high-speed railway catenary. Background technique [0002] With the rapid development of my country's economy, the scale of my country's high-speed railway is constantly expanding. However, since my country is one of the countries with the most climate across regions, icing of the high-speed railway transmission and distribution catenary occurs frequently. As the catenary continues to extend to areas prone to icing, frequent icing accidents are harmful to railway operation. Gradually, it became apparent that the icing of the catenary will have a major impact on pantograph-catenary contact, power extraction, arc drawing, and lifting. At the same time, the working conditions of the high-speed rail transmission and distribution network are quite different from those of the power grid. Therefore, it is imminent to develop corresponding anti-icing and melting techno...

Problems solved by technology

Although the above insulation layer winding method is simple to operate, since the winding direction of the glass filament is consistent with that of the wire, there is no vertical support structure, and the overall insulation layer of the coil is prone to fracture along the transverse direction under the impact of strong electrodynamic force. This leads to a decrease in the airtight performance of the coil, burying hidden dangers for the safe operation of the high-speed rail
