目前,我国镁电解槽启动一般采用二次启动法,本文在参照国内外镁电解槽正常生产能量平衡依据的基础上,初步推导出镁电解槽启动时交流电加热功率选择的计算方法,并用某厂生产启动能耗结果加以论证。其选择依据较为可靠,对今后设计、生产选用可靠电容量交流变压器,特别是大型电解槽启动交流变压器,具有一定的参考意义。 At present, the start-up of magnesia cell in our country generally adopts the second-start-up method. Based on the energy balance of magnesium electrolyzers at home and abroad, the calculation method of AC heating power at the start- Energy production start-up results to be demonstrated. The basis for its choice is more reliable, for the future design, production and selection of reliable capacitance AC transformer, especially large-scale electrolytic cell start AC transformer, has some reference value.
