摘要
随着微机保护成为电力系统继电保护的主流形式 ,数字式电动机保护装置也被研制和应用。文章主要以NFD - 80 0为例讨论数字式电动机保护装置的保护原理和硬件结构 。
With computerized protection having become a major form in power system relay protection, a digital protective device in motor has been developed and used. This paper, taking NFD-800 for example, mainly introduces the principles of digital motor protection and the hardware of protective device, and discusses briefly the possible prospects in this aspect.
