开阳磷矿青莱冲矿区采矿方法试验中,进口设备的电源变压器及配电开关柜均设在+960米水平的变压器峒室,而+940至+970米水平已经采完,采掘工作已转到+930米水平以下。由于进口设备使用的拖 电缆经常漏电,使变压器峒室内线路绝缘电阻监测器动作,配电开关柜停电。操作人员从地面去960变电所要走1.5公里,从井下去则至少走500米,且要经过采空区,很不安全。 鉴于此,笔者设计了一个电路,实现变电所有线远距离监视与操作。
Kaiyang Phosphate Mine Qinglongchong mining area test method, the imported equipment, power transformers and distribution switchgear are located at +960 meters level transformers 峒 room, and +940 to +970 meters have been taken mining, mining work has been Go below +930 meters. Due to the frequent use of towed cables imported equipment imported leakage, so that the transformer 峒 indoor line insulation resistance monitor action, power distribution switchboard power failure. Operators go from the ground to the 960 Substation 1.5 km away from go down to go at least 500 meters, and to go through the goaf, it is not safe. In view of this, I designed a circuit to achieve long-distance substation monitoring and operation of all lines.
