变压器功率损耗分析与提高系统功率因数的措施

本文对变压器损耗进行了理论分析和实际计算,确定了变压器处于轻载状态时,系统功率因数较低的主要原因,由于变压器轻载时二次侧负荷电流下降,其不足以启动无功补偿自动控制器工作,变压器的空载无功损耗也得不到补偿。提出手动控制变压器负荷侧无功补偿电容器的投切,使系统功率因数得到提高。达到降低线路功率损耗、减少供电部门对企业的功率因数考核电费,提高企业经济效益的目的。

Power Transformer and Analysis and Improve the System Power Factor Measures

The loss of the transformer is discussed by theoretical analysis and practical calculation, Determine the transformer is in light load condition, System power factor is the main reason of low, Because the transformer when a light load is two side load current falls, Its not enough to activate the reactive compensation automatic controller, Transformer reactive loss is not compensated. Proposed manual control transformer load side reactive compensation capacitor switching, The power factor of the system is improved, To reduce the line loss of power, Reduce the supply department of the enterprise power factor assessment of electricity, The goal that raises business economic benefits.
