Description :
1. Overview
The AM series microcomputer protection and measurement device (hereinafter referred to as the device) integrates protection, measurement, and control, and is suitable for user terminal substations with voltage levels of 35kV and below. It can achieve protection and measurement of user substations. The application areas cover industries such as power, water conservancy, transportation, petroleum, chemical, coal, metallurgy, etc.
The device adopts advanced, mature and reliable protection principles and algorithms, with strong anti-interference performance, high reliability, flexible protection implementation methods, and redundant communication design. The device has an independent high-precision current measurement circuit, multiple switch quantity acquisition and relay output, which can be used in conjunction with the comprehensive automation system of the substation or the electrical automation system of the power plant, and can achieve unmanned end-user substation distribution automation system. The device can be installed in a centralized manner by grouping screens, or directly installed on the switchgear for decentralized control.
