低压选择性保护技术

Selective Protection Technology in the Low Voltage Distribution System

设计一个供电系统 ,除了设备选型外 ,还要对各级保护设备进行选择性保护配合设计 ,使供电系统具有安全性和可靠性 ,并满足人身和设备的安全要求 ,确保连续供电。施耐德电气公司以高性能的断路器作为标准 ,能提供全选择性配合的解决方案。

The design of LV distribution system should be to deal with the coordination of protective devices, which are located at different points of the system. The total selective protection given by high standard circuit breaker of Schneider ElectrIc will be to increase system’s safety and availability greatly. The selective protection was resumed, The explanation of relations between selective protection and the characteristics of circuit breaker was given. Finally a practical example showed how to deal with the selective protection.
