多通道式探测器
Multichannel detector
在一个探测器上可接入2个及以上的剩余电流互感器，同时监控多个供电回路。有的型号把通道做成卡式组件，每个通道有独立的地址、设置、报警和输出，在相同的探测器机架上可灵活组合成1～10通道探测器。
On one detector, 2 or more residual current transformers can be connected and multiple power supply circuits are monitored. Some models make the channel into a card module. Each channel has an independent address, setting, alarm and output, and can be flexibly combined into a 1~10 channel detector on the same detector rack.
这种方式实际上可看作是若干个探测器与区域控制器的组合，本身就形成了一个简易监控系统。它特别适用于多个需要监控的回路较为集中的地方，例如一级配电柜、小型配电室。一台10通道探测器就可以对500m2以下的网吧、餐厅等营业场所的接地故障进行有效监控，大幅度节省了投资。
This method can be regarded as a combination of detectors and regional controllers, and a simple monitoring system is formed in itself. It is especially suitable for a number of places that need to be monitored more closely, such as first class distribution cabinets and small distribution rooms. A 10 channel detector can effectively monitor the grounding fault of the Internet cafes, restaurants and other business places below 500m2, and save a lot of investment.
