MICP171 保护测控装置
MICP171 protection measurement and control device

使用范围和用途 /Scope and Purpose

MICP171 装置是在多年实践应用和运行经验的基础上，吸取了国内外微机保护装置先进技术，研制推出的
新一代微机保护测控装置。广泛适用于电力、水利 . 石油、化工等行业 35KV 及以下电压等级系统，外形尺
寸紧凑，特别适合作为环网柜的主保护和后备保护。

装置具备完善的保护功能，可集中组屏安装或直接在开关柜上分散安装。装置采用薄型密封式结构设计，
无需前移支架，便可适合环网柜安装。配合通讯管理单元和监控系统，还可以构成完整的厂站自动化系统。
The MICP171 is a new generation of microcomputer protection measurement and control device
developed on the basis of many years of practical application and operating experience, integrated
with the advanced technology of microcomputer protection devices. It is widely used in power, water
conservancy, petroleum, chemical and other industries with a voltage level of 35KV and below. Its
compact dimensions are especially suitable for the main protection and backup protection of ring
network cabinets.
The device has perfect protection functions, which can be installed in groups or installed directly on
the switch cabinet. The device adopts a thin and sealed structure design, which does not need to move
the bracket forward, and is suitable for installation of ring network cabinets. With the communication
management unit and monitoring system, it can also form a complete plant and station automation
system.
