*2种:用电设备本身绝缘损坏而漏电(即设备中的N线与PE线短接)。
故障现象:插座回路用电时,插座回路漏电开关跳闸。
故障原因:经分析线路接线正确无误,负荷计算与漏电开关匹配,故判断为用电设备本身绝缘损坏而漏电(即设备中的N线与PE线短接)。
解决:更换或用电设备,保证用电设备具有良好的绝缘。
*3种:线路绝缘强度或线路短路引起漏电断路器故障跳闸。
故障现象:不用电时,插座回路漏电开关跳闸。
故障原因:经分析,1、线路绝缘强度,泄漏电流**过了漏电开关允许泄漏电流值。2、因线路短路所致。
解决:1、烘干线路,绝缘强度。2、检查线路若是短路所致,排除短路故障。
*4种:有人触电,插座回路漏电断路器跳闸。
故障现象:插座回路漏电开关突然跳闸。
故障原因:有人触电。
解决:宣传教育用户用电,避免触电事故发生,若发现有人触电,应及时抢救伤者。
*5种:员工接线不正确,照明回路中将N线接到PE线上了
故障现象:插座回路能正常用电,照明回路用电时,中的总漏电开关跳闸。
故障原因:经分析,线路接线不正确,将照明回路中的N线误接到PE线上了。
解决:进行改线,将照明回路中的PE线改接到N线上。
*6种:员工接线不正确,插座盒中的N线与PE线接错了
故障现象:照明回路能正常用电,插座回路用电时,ALY中的插座漏电开关跳闸,有时AL1中的总漏电开关也跳闸。

3.生产管理——可追溯性对于食品和饮料工厂经理而言不可或缺。可追溯性不仅能保证出厂前的每批产品质量始终如一,而且确保遵循严格的安全标准。配备强大的过程库的过程自动化系统有助于您完全管理和充分了解整个工厂的生产过程,并详细评估各个生产阶段。
EcoStruxure架构与平台采用了物联网、移动、传感、云、分析和网络安全领域中的技术,以推动从互联互通的产品到边缘控制,再到应用、分析与服务各个层级的全面创新。[1]
(三)开断、关合性能事故开断、关合任务是对断路器严酷的考验。绝大多数开断、关合事故的主要原因是由于断路器有明显的机械缺陷,其次是缺油或油质不符要求。也有是由于断路器断流能力不足。但前者较多,因为有相当数量的事故发生于分、合小容量,甚至是分、合负荷电流。
2019年5月16日,施耐德电气向中国工业用户正式推出了面向工业领域的EcoStruxure。[2-3]EcoStruxure是基于物联网的,开放的、具有互操作性的系统架构与平台,可以为楼宇、基础设施、工业和数据中心领域的用户实现更佳的安全性、可靠性、性、可持续性和互联互通。[1]
