摘要
为研究低压熔断器长期频繁过载运行后对熔断器的动作特性方面的影响,讨论了一种低压熔断器过载测试方法,搭建的测试平台能够输出精确的电流,并采集全面的熔断器测试数据,经过数据分析与处理,能分析出熔断器的性能变化。最后通过对NT2/400A、RT0-600/400A型熔断器实测数据的分析,验证了开展此项研究的必要性。
An overload test method was proposed to study the effect of long-term frequent overload on the action characteristics of the fuse.The test platform built by the method whose output current can be controlled accurately to test the fuse,in the meanwhile all kinds of test data is collected.It can analyze the performance changes of the fuse by processing the collection data.This paper,through analysis of the measured data of NT2/400 A,RT0-600/400 A fuse,verified the necessity of carrying out this study.
