铜陵有色金属公司是一个老企业。设备陈旧、数量多、型号复杂;又由于出厂时间先后相差很大,互换性也差。特别是高压电机,有两个主要生产厂矿使用三千伏和六千伏两种配电电压。造成一个配电所有两种电压的高压配电盘,一个井筒有两种高压的电力电缆,一个车间或站有两种高压配电的电机设备。增加了开关、电力电缆及线路。这不但使管理复杂,也给维修和运行带来了困 Tongling Nonferrous Metals Company is an old business. Outdated equipment, the number of large, complex models; and because the factory has a great difference between time, interchangeability is poor. In particular, high-voltage motors, there are two main production plant mine using three kV and six kV voltage distribution. Resulting in a high-voltage switchboard that distributes both voltages, one high-voltage power cable in one wellbore, and two high-voltage distribution electrical equipment in a workshop or station. Added switches, power cables and wiring. This not only complicates management but also brings difficulties to maintenance and operation
