在工业企业电力供应设计中,一般采用需要系数法和二项式法确定电力计算负荷。需要系数法是将电力设备容量乘以需要系数 Kc 即得出计算负荷。过去我们采用苏联54年电工手册中所登载的需要系数 Kc。我们听到一些工厂反映说,设计单位计算的电力负荷较工厂实际运转后的电力负荷为大,浪费了设备和投资;我们 In the design of power supply for industrial enterprises, the required coefficient method and the binomial method are generally used to determine the power calculation load. The coefficient method is needed to calculate the load by multiplying the power equipment capacity by the required coefficient Kc. In the past we used the demand coefficient Kc published in the Soviet Union’s 54th Electrician’s Manual. We heard from some factories that the power load calculated by the design unit is greater than the actual load after the actual operation of the factory, wasting equipment and investment; we
