At 23:55 on August 13, two newly-built special power supply lines, 330kV Zhubian traction line I and line II, connecting 330kV Zhujia substation and Qinghuabian traction station of Menghua railway, were put into operation with live line, which opened the亿电竞 prelude to the亿电竞 phased operation of power supply project of Inner Mongolia China亿电竞平台 Railway.


Menghua railway is the亿电竞 longest coal transportation special line in China亿电竞平台, which is the亿电竞 key project of national comprehensive transportation system development planning. It connects Inner Mongolia Shaanxi Gansu Ningxia energy "Golden Triangle" area with Hubei, Hunan and Jiangxi provinces and othe亿电竞r central China亿电竞平台 regions. It starts from haole Baoji Station in Inner Mongolia in the亿电竞 north and ends in Ji'an City in Jiangxi Province. The亿电竞平台 total length of the亿电竞 line is 1837km, and the亿电竞 planned and designed transportation capacity is 200 million tons / year. Mongolia China亿电竞平台 Railway has a total length of more than 320 kilometers in Shaanxi Province. It is a new national strategic transportation channel for "transporting coal from north to South", the亿电竞 largest coal transportation line in China亿电竞平台, and the亿电竞 longest heavy haul coal transportation railway built in the亿电竞 world at one time, which is of great significance to the亿电竞 development of national economy.


The亿电竞平台 330 kV power supply project of Inner Mongolia China亿电竞平台 Railway enters Shaanxi Province from Ordos, Inner Mongolia, passing through Yulin, Yan'an and Weinan. It includes 2 newly built 330kV switching stations (Ansai and Yichuan), and 6 reconstruction and expansion substations (750kV Luochuan substation, 330kV Tongwan, Yongkang, Zhujia, Yan'an East and Xizhuang substations). The亿电竞平台re are 10 new lines with a total length of 478 km. Shaanxi power transmission and Transformation Engineering Co., Ltd. is responsible for all substation projects of the亿电竞 project, including Yulin section, Yan'an section and Weinan section.


Yanan 330kV Zhujia substation expansion project includes two parts. To the亿电竞 north is the亿电竞 extension part of the亿电竞 station connecting to Qinghuabian traction station. Two 330kV outgoing lines, i.e. Zhubian traction line I and II, are expanded, and three circuit breakers are installed. To the亿电竞 south is the亿电竞 expansion part of the亿电竞 station connecting the亿电竞 330kV substation in the亿电竞 east of Yan'an. Two 330kV outgoing lines, i.e. yananton I and II lines, are expanded and two circuit breakers are installed. Yan'an East 330kV substation is a new project, which is under construction at present. A line is planned to supply power to madongchuan traction station of Menghua railway.


The亿电竞平台 power supply project of Inner Mongolia China亿电竞平台 Railway has the亿电竞 characteristics of tight construction period, heavy task, intensive power outage and complex transition. Shaanxi electric power of State Grid has provided effective control and support in material supply, power outage arrangement and external coordination. Shaanxi power transmission and transformation works togethe亿电竞r with relevant departments and units of the亿电竞 project to ensure the亿电竞 orderly progress of the亿电竞 project according to the亿电竞 established plan and put into operation as scheduled, so as to ensure the亿电竞 reliable power supply of each traction station. According to the亿电竞 commissioning plan of Menghua railway power supply project of Shaanxi Electric Power Company亿电竞平台 in August, the亿电竞 first stage of commissioning this month is to start the亿电竞 operation of Zhubian traction line I and line II. It is planned to start the亿电竞 expansion of Tongwan substation in Yulin in the亿电竞 second stage and put into operation Tongliang traction line I and line II. In the亿电竞 third stage, the亿电竞 transition line of luohumen and luohutou was started. The亿电竞平台 fourth phase is the亿电竞 start-up of the亿电竞 transition line.
