摘要(Abstract):
通过分析得出电容器熔丝熔断时一次电压值的计算公式,改进了不平衡电压测试的方法,经过试验值和实际值的对比,验证了测试方法的可行性。应用新方法后在带负荷试验时不必再做不平衡试验,省时省力,也降低了投产安全风险。
The calculation formula of primary voltage value is obtained through the analysis when the capacitor fuse is blown.The unbalanced voltage test method is improved.Through the comparison of test value and actual value,the method feasibility is verified.By applying the new method,there's no need of imbalance test in the on-load tests.It reduces time and effort as well as operation safety risk.
