我矿有电机车二十多台,每年消耗控制器接点量较大,价值三万多元,特别是当前在接点货源不足的情况下,迫切需要设法解决这一问题。我们经过调查了解到,控制器上的铜接点由于频繁闭合,使用寿命较短,耗费量较大。我们试用合金片做接点,获得了成功。我们把旧的合金片和用过的旧接点回收起来,锯掉接点头部,用铜焊方法将接点的尾部和合金片联结 I mine more than 20 electric locomotives, the controller consumes a large amount of contact each year, the value of more than 30,000 yuan, especially in the current shortage of contacts under the circumstances, the urgent need to find ways to solve this problem. After investigation we learned that the copper contacts on the controller due to frequent closure, shorter life expectancy, greater consumption. We try to contact the alloy sheet, has been successful. We have the old alloy film and used old contacts recovered, saw off the head contacts, the contact method with the tail of the alloy sheet and the link
