SYSTEM OVERVIEW系统说明 · SYSTEM RELATIONSHIPS
See how isolation, monitoring, fault location and alarms relate. The project electrical design determines the final topology and equipment selection.了解隔离、监视、故障定位和报警设备如何配合。最终系统结构和设备选型应由项目电气设计确定。
01 / HOW THE PRODUCTS WORK TOGETHER设备如何配合
Isolation, monitoring, fault location and alarms work together around defined circuits and the people who use the system.隔离供电、绝缘监视、故障定位和报警围绕明确的供电回路与使用人员协同工作。
The transformer supplies the isolated circuit defined by the project design. Downstream distribution serves the designated rooms and loads.隔离变压器为项目设计确定的回路供电，下游配电再连接指定房间和用电设备。
