在煤矿井下运输中,除主要运输巷外,还有许多支巷和煤矸装载点,这些支巷的断面一般较小,电机车架空线高度也较低,而且经常有人员通行和工作。因此我矿在这里发生的人身触电事故次数最多。为了改变这种状况,我们于1983年研制了架线电机车支巷网路自动停送电控制器,在使用中经过几次改进,已于1985年定型使用至今,使用效果良好,从未发生异常现象,有效地防止了由支巷架线引起的人身触电事故。此种装置安装
In coal mine transportation, in addition to the main transport lane, there are many branch lanes and coal gangue loading points. The cross sections of these branch lanes are generally small, the height of overhead lines of motor vehicles is also low, and there are often people passing and working. Therefore, I mine the highest number of personal electric shock accidents occurred here. In order to change this kind of situation, we developed the automatic stopping electric controller of overhead line electric locomotive roadway network in 1983, after several improvements in use, it has been used well since 1985 and has been used well. It never happened Abnormal phenomenon, effectively preventing the personal electrical shock caused by the tributary lane. Such a device is installed
