摘要
通过改动1台低压真空馈电开关(KBD-350/660Z:徐州煤矿工程机械装备有限公司生产)芯子中的一组控制接线,并使之与煤矿井下局部通风机启动开关及瓦斯监控系统配合使用,就能达到煤矿井下供电系统的"风电"、"瓦斯电"闭锁的目的。在保证煤矿井下低压供电质量和安全的前提下,使每个"风电"、"瓦斯电"闭锁系统中减少1台真空磁力起动器,减少了安装中的工作量,并减少了一个故障出现点。
Changes a set of control wiring of a low voltage vacuum feed switch cores （KBD-350/660Z Xuzhou construction machinery equipment Co., coal production）, and make it and the local fans and coal mine gas monitoring system start switch used in conjunction, mine power systems can meet the ＂wind power＂,＂gas power＂ closedown purposes. On the ensure quality and safety of low-voltage power supply in the coal mine condition, reducing installation effort and reduce the emergence of a failure point in each ＂wind power＂, ＂gas power＂ closed system to reduce a vacuum magnetic starter.
