对于高压电源与采掘设备之间的连接,我国大部分露天矿山都是采用弯钩挂铜线“鼻子”。但这种挂接装置有许多缺点,给设备带来很大损失。仅在1990年,我矿因此而烧毁电机(250kW/6W)10台,辅助电机数十台。直接经济损失高达10万元左右。为此,经现场收集数据,反复试验,终于设计制造出一种能满足生产要求的挂接装置。通过在凹山采场的使用(共计 For the connection between high-voltage power supply and mining equipment, most of the open-pit mines in our country adopt the “nose” of hooked copper wire. However, there are a number of disadvantages associated with this type of attachment, which can result in significant loss of equipment. In 1990 alone, mine burned 10 motors (250kW / 6W) and dozens of auxiliary motors. Direct economic loss of up to 10 million. To this end, the data collected on the spot, repeated testing, and finally designed to create a meet the production requirements of the articulated device. Through the use of the concave hill stope (total
