对建筑物内低压配电系统采用环形供电的探讨

环形供电作为一种供电方式，国内在建筑物内低压配电系统方面介绍和应用都比较少。本文对各种低压供电方式从技术经济方面进行对比，对低压系统采用环形供电（终端环形电路、环形供电干线）进行一定的探讨，并介绍国外应用的实例。

Discussion about Adopting Loop Power Supply for Low-voltage Distribution System inside the Buildings

Loop power supply is a kind of power supply method, but the introduction and application in the low-voltage distribution system inside the buildings at home are relatively fewer. In this paper, different kinds of low-voltage power supply methods are compared from the aspects of technology and economy, and the loop power supply adopted in the low-voltage system (terminal loop circuits and loop power supply mains)are somewhat discussed. Application examples abroad are also introduced.
