微机消谐装置特点
Characteristics of microcomputer harmonic elimination device
(1)数据采集、运算、逻辑判断、控制输出等速度快，精度高，抗干扰、自检及自恢复能力强； (2)综合国内各种先进技术，多年的现场运行经验，性能稳定，安全可靠；
(1) the speed of data acquisition, operation, logic judgment, control output and so on is fast, high precision, anti-interference, self inspection and self recovery ability; (2) comprehensive domestic advanced technology, years of field operation experience, stable performance, safe and reliable;
(3)采用液晶显示器（LCD），中文菜单，显示信息直观；
(3) use liquid crystal display (LCD), Chinese menu, and display information intuitively;
(4)实时显示PT开口三角电压4种频率（3分频/17Hz、2分频/25Hz、工频/50Hz、3倍频/150Hz）的电压分量；
(4) real-time display the voltage components of PT open delta voltage at 4 frequencies (3 frequency /17Hz, 2 frequency division /25Hz, power frequency /50Hz, 3 frequency doubling /150Hz).
(5)可以判别过电压、铁磁谐振以及单相接地，并对铁磁谐振迅速消除；对各种故障均可给出告警信号并显示、打印和保存有关信息；并可以及时打印输出故障报告（故障类型、故障时间及PT开口三角电压4种频率的电压分量）；
(5) the overvoltage, ferromagnetic resonance and single-phase grounding can be discriminated, and ferromagnetic resonance can be eliminated quickly; alarm signals can be displayed, printed and stored for various faults, and the output fault report (fault type, fault time and voltage component of 4 frequencies of PT opening triangle voltage) can be printed in time.
(6)有记忆功能，可存储4次最近发生的故障信息，掉电后不丢失；
(6) with memory function, it can store 4 recent fault information and do not lose after power failure.
(7)采用大功率、无触点消谐元件，启动迅速；
(7) use high-power, contactless harmonic elimination elements to start quickly.
(8)调试和维护简单、方便；
(8) the debugging and maintenance are simple and convenient.
(9)适用于各种电压等级的PT；
(9) PT suitable for various voltage levels;
(10)可配置通信接口把各种故障信息传送至有关部门，适用于无人职守变电站 [2]
