浙江漓渚铁矿原有的供电电压波动较大,6千伏母线电压白天最低为5.1千伏,而晚上最高升至6.9千伏,严重影响矿山正常生产。该矿职工在工业学大庆的群众运动中,急生产之所急,自力更生,大搞革新、挖潜,改制成功一台能带负荷升降压的调压变压器,将其串在矿山35/6千伏1800千伏安主变压器上,可使矿区6千伏电压保持在5.7～6.3千伏(即波动±5%)的范围内,保证了矿区正常生产。实践表明,运行情况良好。本刊特约撰文介绍,供有关矿山参考。
The original supply voltage of Lizhu Iron Mine fluctuated greatly in Zhejiang Province. The minimum voltage of 6 kV busbar was 5.1 kV during the day and rose to 6.9 kV at night, seriously affecting the normal production of mines. The mine workers in the industrialization of Daqing mass movement, the urgency of emergency production, relying on one’s own efforts, innovation, tapping the potential, restructuring success with a load-lifting pressure regulating transformer, the string in the mine 35/6 thousand An 1800 volt An main transformer, the mining 6 kV voltage can be maintained at 5.7 to 6.3 kV (ie, fluctuations of ± 5%) within the scope of the mine to ensure the normal production. Practice shows that the operation is good. Articles dedicated author introduction, for the mine reference.
