我厂与煤炭科学院开采所,在8230厂的协作下,研制成功了DKZB—400/1140矿用隔爆型真空馈电开关(以下简称真空馈电开关),于1983年初通过煤炭部技术鉴定,並已生产100多台,先后在全国十几个矿务局投入使用。本文仅就真空馈电开关与煤矿安全问题作一简要分析。一、DKZB型真空馈电开关的主要技术性能本真空馈电开关在煤矿井下1140V或660V
I plant and the Academy of Coal Mining, 8230 plant in collaboration with the successful development of the DKZB-400/1140 Mining Flameproof vacuum feed switch (hereinafter referred to as the vacuum feed switch), in early 1983 through the Ministry of Coal technical appraisal, And has produced more than 100 units, has more than a dozen mining bureau in the country put into use. In this paper, only a brief analysis of the vacuum feed switch and coal mine safety issues. First, the main technical performance DKZB-type vacuum feed switch The vacuum feed switch in the coal mine 1140V or 660V
