Abstract

The invention relates to the technical field of railway power supply, and provides a traction power supply system with ice melting and energy feedback functions, the traction power supply system comprises a plurality of power supply sections, each power supply section is correspondingly provided with a traction transformer, and each power supply section is provided with a rectifier unit traction station or a flexible direct current traction station; the input end of the rectifier unit traction station is connected with the traction transformer, the output positive electrode of the rectifier unit traction station is connected with the uplink power supply rail through the power supply switch, and the output negative electrode of the rectifier unit traction station is connected with the upper walking rail; an output positive electrode of the flexible direct current traction station is connected with the uplink power supply rail through a first switch, an output negative electrode of the direct current traction station is connected with the upper walking rail through a fourth switch, each power supply section is provided with a fifth switch, one end of each fifth switch is connected with the uplink power supply rail, and the other end of each fifth switch is connected with the upper walking rail. According to the technical scheme, the problems of complex ice melting operation and high energy consumption of the traction power supply track in the prior art are solved.

Description

technical field [0001] The invention relates to the technical field of railway power supply, in particular to a traction power supply system with functions of ice melting and energy feeding. Background technique [0002] At present, the rapid development of China's high-speed railway, urban light rail and other rail transportation industries has become an important way for people to travel, bringing great convenience to daily life. However, the locomotive traction power supply track is exposed to complex and changeable natural environments, and icing problems will occur under harsh ambient temperature and humidity conditions, resulting in the failure of the locomotive pantograph to receive power normally, affecting the operation of the locomotive, and even causing the pantograph Damage and locomotive operation accidents. Therefore, research on melting ice or preventing icing on traction power supply rails is an urgent problem to be solved for the realization of electrified ...
