在铁合金冶炼中,为了监测每相电极的冶炼电流,常在变压器高压侧安装有电流表,以便控制电流的大小。为了使电流表所指示的读数能正确反映出相对应电极的工作情况,电流表的接法必须与变压器的接线组别相适应。宝鸡地区某铁合金厂,由于没有注意到这个问题,炉子投产近一年一直不能正常运行。在炉况正常时似乎还能操作,炉况一旦恶化,操作人员就根本无法控制。开始他们
In ferroalloy smelting, in order to monitor the smelting current of each phase electrode, ammeter is usually installed on the high voltage side of the transformer in order to control the current size. In order for the ammeter to indicate the readings can correctly reflect the work of the corresponding electrode, the ammeter connection must be compatible with the transformer wiring group. A ferroalloy plant in Baoji area, because did not notice this problem, the stove put into operation for nearly a year has been unable to operate normally. Seems to be able to operate at normal furnace conditions, once deteriorating furnace conditions, the operator simply can not control. Start with them
