摘要
电炉炼钢和电气化铁路都是严重的谐波和不平衡负荷,监测它们对系统的危害,只从谐波和负序电流单独来看,往往是不够的。谐波和不平衡电流都会对系统中所有电机造成危害,本仪器对含谐波和不对称的负荷还可测量其异步电流Ig(t)和异步能量W1(t),动态异步能量W2(t)是由W1(t)用散热的方法计算得出。我院研制的KC-3301A电能质量分析仪,具有测量谐波、电压闪变、三相不平衡、电参数等规程指标外,包括上述所有电能质量的新概念的指标。
The electric steel-making and electrization railway are harmonic & unbalance load.The view single of the harm on electric system from harmonic or unbalance current is not enough. Both harmonic & unbalance currents can make damage on all electric motor in system. The instrument can measure the asynchronous current Ig(t) & energy W1(t) of harmonic & asymmetric electric power loads, the dynamic Asynchronous current energy W2(t) is calculated by use of thermal consumption from W1(t). The instrument of KC-3301A have the ability to measure harmonic,flicker,unbalance,electric parameter and above all.
