智能电网对低压配电电器的要求

Smart Grid Requirements for Low- voltage Distribution Apparatus

阐述了智能电网涉及到的领域、建立智能电网的目的和实现智能电网的手段。从适应建立智能电网的要求出发，提出低压配电电器的发展趋势：性能上应包括高可靠性、关注系统解决方案、全选择性保护、高短路能力、高寿命、智能化、网络化、环保、对特殊环境的适应性、过电压保护；结构上包括模块化、小型化和安装多样化等。

This paper introduces the field of the smart grid, the purpose of buiding smart grid and the method to realize the smart grid. The developmert ternd of Low - voltage distribution apparatus has been put forward at the requirements of buiding the smart grid. The performance of low - voltage distribution apparatus shoud include high reliability, system solution, full selectivity, high interrupt capacity, high enderance life, intelligence - networked, environment protection, the adaption for special environment, over - voltage protection. And the instruction of its should include modularization, miniturization and diversified mounting.
