非对称开断试验中的操作顺序问题研究

Research on Operating Sequence Problem in Asymmetric Short-Circuit Current Breaking Test

介绍了以试验方式为非对称开断的试验中进行额定操作顺序问题的必要性和实施的可行性,对试验标准、试验室的试验运行和制造厂技术成本所带来的影响进行了阐述,并从不同角度论述了附加验证试验的必要性,分析结果表明,对通用型的高压断路器没有必要进行附加操作顺序的非对称开断试验。

Introduction was made to the necessity and implementary feasibility of rated operating sequence problem in the test method of asymmetric short-circuit current breaking test. This paper expounded the impacts of test standards, laboratory tests and manufacturing tech- nology running costs, and discussed the necessity of additional verification test from different comers. The analysis result shows that there is no need to add the asymmetric short-circuit current breaking test of operating sequence for the general type of high-voltage circuit breakers.
