摘要
低压电器进行分断能力试验时,为了模拟感性负载的电路条件,需依据国标,将负载电路的振荡频率f与过振荡系数γ调整至要求范围内。而振荡频率f与过振荡系数γ的手动调整过程比较复杂,效率较低。针对上述问题,搭建基于Lab VIEW与Multisim的f、γ电路仿真模型与自动调节装置,实现振荡频率f与过振荡系数γ自动调节,大大提高了试验效率。
During the breaking capacity test of low-voltage apparatus,in order to simulate the circuit conditions of inductive load,the oscillation frequency f and oscillatory factor γ of load circuit shall be determined accor ding to the national standard.The manual adjustment process of is complex.And efficiency is relatively low.To solve the above problems,building the Circuit simulation analysis model and automatic regulation device based on Labview and Multisim.The automatic adjustment of oscillation frequency and oscillatory factor is realized,which greatly improves the test efficiency.
