兰尖铁矿平峒车间尖1号板式给矿机是兰尖矿尖山采场矿石输出过程中的一个重要环节。其工作是否正常直接影响到兰尖矿矿石产量以及矿业公司铁精矿产量。放矿过程中,该给矿机的链带滚动靠2台60 kW的绕线式异步电动机带动。由于放矿工作的特殊性,要求频繁地同时启停这2台电机。2台电机采用的启动方法是电机转子回路串频敏变阻器启动,启动过程中在转子回路中串入频敏变阻器,启动 Lan sharp iron ore flat 峒 workshop tip 1 plate to the mine machine is Lanjian mine Jianshan stope ore output in an important part of the process. Whether its work is a normal direct impact on the blue-point ore production and iron ore mining company output. In the process of ore drawing, the chain belt rolling of the ore machine is driven by two 60 kW windings asynchronous motors. Due to the particularity of the ore drawing work, it is required to start and stop these two motors frequently at the same time. 2 sets of motor start-up method is to use the motor rotor loop frequency-sensitive rheostat start, start the process of the rotor loop into the frequency-sensitive rheostat, start
