在矿山机电工作中,经常遇到绞车的安装。在计算绞车拖动电机的起动电阻时,也常因缺少数据而苦恼。中小型矿山中常用的提升绞车一般的容量都在50～150千瓦之间,而且由于客观上的因素,实际电阻的配搭也不十分准确。因此,过于追求计算上的精确显得不必要。本文试图综合有关各种方法,对矿山提升绞车中小型绕线电机起动附加电阻的计算进行简化,以便现场凭一些垂手可得的数据进行计算。
Mechanical and electrical work in the mine, often encountered winch installation. In calculating the winch drag motor starting resistance, often due to lack of data and distressed. The commonly used hoisting winches in small and medium-sized mines generally have a capacity of 50-150 kilowatts, and due to objective factors, actual resistance matching is not very accurate either. Therefore, excessive pursuit of computational precision appears unnecessary. This article attempts to synthesize the various methods to simplify the calculation of the additional resistance of small and medium-sized winding motors in mine hoisting winch so as to make some on-the-spot calculations with the available data.
