为预防煤矿井下用架线式电机车运送人员或在架线下作业时,发生触电事故,《煤矿安全规程》规定,架空线必须设分段开关,人员上下车时,必须切断该区段架空线的电源,以确保上下车人员的安全。根据这一规定,我们研制成功了架线电机车区段网路电源自动控制器、经试验情况证明,它的工作稳定可靠,线路简单,制作容易。对于经常有人员工作的溜煤眼和平时少有机车去的支巷架空线,也非常适用。这一装置的研制成功,为矿山安全生产,带来了很大的方便。 此装置安装在乘人车场,溜煤眼附近和支巷的架空线上,平时该区段架空线路处于停电状态,人员可以在此地区安全工作和上下车。当有机车开来时,可预先发出
In order to prevent electric shock accidents when carrying overhead line electric vehicles in coal mines or working under wires, the Coal Mine Safety Regulations stipulate that the overhead lines must be provided with a section switch. When a person gets on and off the vehicle, he must cut off the overhead Line power to ensure the safety of passengers on and off. According to this regulation, we have successfully developed an automatic controller for overhead line power supply of overhead line locomotive. The test proves that its work is stable and reliable, the circuit is simple and the production is easy. It is also very suitable for the overpass line where there are few locomotives that often have personnel to work and rarely locomotives go down. The successful development of this device has brought great convenience to mine safety production. This device is installed in the passenger car yard, near the coal sliver and overpass overhead lines, usually overhead section of the section in a power outage, staff can work safely in this area and get on and off. When a motorcycle comes out, it can be issued in advance
