由长沙变压器厂设计、制造的KSJ_7型低损耗矿用电力变压器,采用了Q_(10)—0.35优质晶粒取向冷轧硅钢片,铁芯采用45°全接缝无冲孔绑扎结构,为电子计算机优化设计出的节能产品。 该变压器的空载损耗比部标J_B 619—75冷轧钢片平均低46％,短路损耗平均低8.9％,总损耗平均低16.7％。与SJ_7型变压器相比,KSJ_7型空载损耗平均低8.11％,短路损耗平均低3.64％,总损耗平均降低4.11％。若以KSJ_7—315/6.型代替KSJ—315/6变压器运行,每年可节电7000度左右,节电效果明显。
Designed and manufactured by Changsha Transformer Factory, KSJ_7 low-loss mining power transformer adopts Q_ (10) -0.35 high-quality grain-oriented cold-rolled silicon steel sheet. The core adopts 45 ° full seam without punching and binding structure, Computer-optimized design of energy-saving products. The transformer has a no-load loss of 46% lower than the standard J_B 619-75 cold-rolled steel sheet, an average of 8.9% short-circuit loss and an average total loss of 16.7%. Compared with the SJ_7 type transformer, KSJ_7 type no-load loss average low 8.11%, short-circuit loss average low 3.64%, the average total loss decreased 4.11%. If the KSJ_7-315 / 6. Type instead of KSJ-315/6 transformer operation, annual saving of about 7000 degrees, energy-saving effect is obvious.
