问:电抗器在电炉变压器冶炼生产中起什么作用? 答:电炉装料后开始冶炼时,将电抗器投入运行,起稳定电弧作用,可以避免时而点弧时而减弧的现象;所以比较容易点弧,这可保证电炉点弧,也防止大电流冲击变压器,使设备和工作条件安全可靠。经过一段时间,即大电流冲击停止后,可断开电抗器。但当炉料已开始熔化将要塌料时,则把它投入运行,直到炉料倒塌完毕再断开。电抗器投入运行后不应过早断开,否则变压器将遭到大电流的冲击,设备工作条件变坏而且增加电耗。但使用电抗器的时间
Q: What is the role of reactors in the smelting of EAF? A. When starting smelting after charging in the EAF, the reactors are put into operation, which can stabilize the arc and avoid arcs from time to time. Therefore, it is easier to point out Arc, which can guarantee arc furnace, but also to prevent the impact of large current transformer, the equipment and working conditions are safe and reliable. After a period of time, that is, the impact of large current stop, disconnect the reactor. However, when the charge has begun to melt and will collapse, put it into operation until the charge collapses and then disconnect. The reactor should not be disconnected prematurely after it is put into operation, otherwise the transformer will be hit by high current, the working conditions of the equipment will deteriorate and the power consumption will increase. But the time to use the reactor
