| 剩余电流式电气火灾监控探测器的选型 Selection of residual current type electric fire monitoring detector 不同形式的剩余电流式探测器，各有特点、各有所长，不能以形式“分代”，也不是孰优孰劣的问题。现在来预测剩余电流式探测器的结构“发展方向”尚为时过早。对于不同的场合，有不同的使用需求，设计电气火灾监控系统时应进行合理的选型。 Different types of residual current detectors have their own characteristics and advantages. They can not be classified in the form of "generational" or "inferior". It is too early to predict the structural development direction of residual current detectors. For different occasions, there are different requirements for use. When designing an electrical fire monitoring system, a reasonable selection should be made. 1、应掌握的几个原则 1. Several principles to be mastered ●选用经过国家消防电子产品质量监督检验中心型式检验的产品，不能用没有消防检验报告的产品。 Choose products that have passed the type inspection of the national fire control electronic product quality supervision and inspection center, and can not use products without fire inspection reports. ●选用生产工艺成熟、服务有保障、有历史积淀的产品，慎用未经长期实践应用考验的产品（不论多么廉价）。 Choose products that are mature in production technology, reliable in service and accumulated in history, and use products that are not tested for a long time, no matter how cheap they are. ●尽量选用同一系列的产品，避免选用过多的型号。这有利于安装调试、运行管理、维修服务。 Try to use the same series of products to avoid overselection. This is conducive to installation, commissioning, operation management and maintenance services. 2、应考虑的几个细节 2. Some details to be considered ●宜采用独立式探测器，使现场人员能更直接地得到报警信息。 It is advisable to use independent detectors to enable on-site personnel to get alarm information more directly. ●当监控点相对集中时（如变电房内的开关柜），可采用多通道探测器，以简化安装及节省投资。 When the monitoring points are relatively concentrated (such as switchgear in the transformer room), multi-channel detectors can be used to simplify installation and save investment. ●应选择报警值和动作时间可调、剩余电流值可显示的探测器。这样不仅可以现场设定报警值，避免灵敏度过高、实现选择性保护，又可掌握正常运行时的泄漏电流值，为故障的处理提供参考依据。 It should select the detector with adjustable alarm value and action time, and the remaining current value can be displayed. This not only can set the alarm value in the field, avoid the high sensitivity, realize the selective protection, but also can master the leakage current value of the normal operation, and provide the reference basis for the fault treatment. |
