矿井供电谐波危害及治理探究

Research on the harmonic wave hazard and control of the mine power supply

随着电子技术的迅猛发展,在矿井中采用了大量的晶闸管整流电源,使得非线性电气设备产生大量的谐波流入到电网当中,这种谐波对电网产生污染,会导致电路用电效率的下降,严重时会导致电器元件以及矿井设备的损害。本文尝试探究矿井供电系统中谐波产生的原因、危害及消除谐波的措施。

with the rapid development of electronic technology, a great deal use of thyristor rectifier in the mine causes the harmonics wave generated by the nonlinear electrical equipment flow into the power grid, which will pollute the power grid, decrease the efficiency of electricity circuit, and cause serious damage to the equipment and electrical components of mine. This paper attempts to explore the causes of the harmonic generation in the mine power supply system, the harm and the elimination of harmonic measures.
