应用△P_L＝3I^2_LR·10^（－3）KW公式开展节电技改工作

Launching Tcchnical Innovation of Econ omiization on Electricity with Formula

从西南民族学院供电线路实际，应用供电线路能量损耗公式△Ｐｔ＝３Ｉ￣２＿ＬＲ·１０￣（－３）ＫＷ，采用环形供电方案减少线路电阻，提高线路功率因素和控制用电负荷减少线路电流，并对开展节电技术工作提出了可行的建议。

Frum the actural cundltiun of the cireuit at the Southwest Natiunl itiee Cullege,the formula of energy loss in clrcuit is applied so as to reduce resistance with the scheme of ringlike-typo power supply,As a result,the factur of increasing the electric capacity wlll beimproved,the electric luad will be contrulled and electric current will be reduced in circuit,which putsfur ward a feasible suggeatiun to the technical innovat iun of ecununiimtion in electricity。
