丹大高铁明阳牵引站两相供电系统电能表接线分析

Analysis of Two-Phase Power Supply System Watt-Hour Meter Wiring in Mingyang Traction Station for Dandong-Dalian High Speed Rail

丹大高铁是规划建设的东北东部铁路通道的重要组成部分,共分3段:丹东至庄河段、金州登沙河至庄河段和大连至登沙河段,线路自大连北站接轨,抵达丹东。全线共设5座牵引站,均采用两相直供电方式,电能表接线可能存在误接线问题。在此,以明阳牵引站的实例分析两相供电系统电能表接线问题,确定正确接线,达到准确计量电量的目标。

Dandong-Dalian High Speed Rail is an important part of the eastern railway passage in the Northeast China, which consists of three sections, i. e. Dandong to Zhuanghe, Jinzhou Dengshahe to Zhuanghe and Dalian to Dengshahe. The lines are connected at Dalian North Station and extend to Dandong. A total of five traction stations are set up along the railway and all use two-phase direct power supply, and errors may occur in the wiring of watt-hour meters. For this purpose, this paper hereby analyzes the wring of twophase power supply system watt-hour metersby taking Mingyang Traction Station for example, so as to determine the correct wiring and achieve the goal of accurate electrical energy measuring.
