RCBO各标准试验程序和国家差异分析

Analysis of RCBO Standard Test Procedures Differences and National Standard Requirements Differences

在研究剩余电流动作断路器(RCBO)国内外现行或适用标准的基础上,分析了国内外标准之间的差异和各个国家对该产品的要求差异。从试验程序、在剩余电流条件下动作特性试验、短路试验、过电流脱扣特性试验、额定剩余接通和分断能力试验的差别进行研究,帮助RCBO制造商了解不同标准之间的差异和不同国家对该产品的要求差异,以便设计生产的RCBO能满足相应标准和国家的要求。

Based on the study of the current and applicable standards of residual current operated circuit-breaker (RCBO) domestic and overseas,this paper analyzed the differences between domestic standards and overseas standards.Moreover,it examined the differences in various national standard requirements of the product.This research focused on the differences in the test procedure,operating characteristic test under residual current condition,short-circuit test,over-current tripping characteristic test,and residual making and breaking capacity test.The results could help the manufacturers of RCBO understand the differences in various standards and assist them get to know the diverse national requirements of the product.Therefore,the RCBO products could meet the demand of corresponding standards and requirements.
