一、概况近年来,随着形势的发展,养路机械化工作有了较大的进展。发展机械化养路、养桥作业,其主要关键之一,是动力电源问题。我们已在宝成线某区段架设一条三相三线制400伏电线路,并于一定距离内安设插销,以利随时用电方便。该段有的地段原设有10千伏和6600伏高压线,有些地方安设有厂矿、企业、部队的变压器,因而提供了一些便利条件。我们架设这条线路主要是沿铁路接触网杆塔架设,目前已架设72.3公里,已通电使用的有30余公里,部分分段通电的有15公里,还有部分线路
I. Overview In recent years, with the development of the situation, great progress has been made in the mechanization of road maintenance. The development of mechanized road maintenance, bridge maintenance operations, one of the main key is the power supply problem. We have erected a 400-volt three-phase three-wire electric circuit in a certain section of Po Shing Line and installed a latch at a certain distance to facilitate the ready use of electricity at any time. Some sections of the original section of the 10 kV and 6600 volts high-voltage lines, in some places set up factories and mines, enterprises, the military’s transformers, thus providing some convenience. We set up this line is mainly along the railway contact with the tower pole erection, has been erected 72.3 kilometers, has been used in power over 30 kilometers, some sections of the power of 15 km, there are some lines
