The invention relates to an ice melting device for an overhead line system of an electrified railway. The ice melting device for the overhead line system of the electrified railway comprises a voltage transformation assembly and a single-group H-bridge rectifying circuit, the input end of the transformation assembly is connected with a single-phase traction network so as to access a single-phase voltage; the output end of the voltage transformation assembly is connected with the single-group H-bridge rectification circuit; the voltage transformation assembly is used for converting accessed single-phase voltage into first target voltage; the single-group H-bridge rectification circuit is used for converting the first target voltage into a second target voltage to be output so as to melt ice on the overhead line system; wherein the first target voltage and the single-phase voltage are both alternating voltages, and the first target voltage is smaller than the single-phase voltage; the second target voltage is direct current voltage. Therefore, on the basis of accessing the single-phase voltage, the first alternating-current target voltage is converted into the second direct-current target voltage through the single-group H-bridge rectifying circuit, so that the ice melting device for the electrified railway contact network, which is easy and flexible to use and simple in structure, is formed, and the ice melting requirement of the railway contact network can be better met.
本公开涉及一种电气化铁路接触网融冰装置,该电气化铁路接触网融冰装置包括:变压组件以及单组H桥整流电路;变压组件的输入端与单相牵引网连接,以接入单相电压;变压组件的输出端与单组H桥整流电路连接;变压组件用于将接入的单相电压转换为第一目标电压;单组H桥整流电路用于将第一目标电压转换为待输出的第二目标电压以对接触网融冰;其中,第一目标电压与单相电压均为交流电压且第一目标电压小于单相电压;第二目标电压为直流电压。如此,在接入单相电压的基础上,通过单组H桥整流电路将交流的第一目标电压转换为直流的第二目标电压,形成易于灵活使用且结构简单的电气化铁路接触网融冰装置,利于更好地满足铁路接触网的融冰需求。
