ZRCT-TZX微机消谐
ZRCT-TZX Microcomputer Harmonic Elimination 

功能:实时监测PT开口三角电压,消除铁磁谐振。
Functions: Real-time monitoring PT open delta voltage to eliminate ferroresonance.
工作原理:本装置采用最新DSP单片机作为核心元件,对PT开口三角电压(即零序电压)进行循环检测。当该电压小于30V时,装置内的大功率消谐元件处于阻断状态,对系统无任何影响;当该电压大于30V时,开始对开口三角电压进行数据采集,通过数字测量、滤波、放大等数字信号处理技术,然后对数据进行分析、计算、判断出当前的故障状态。如果出现某种频率的铁磁谐振,CPU立即启动消谐电路让铁磁谐振在强大的阻尼下迅速消失。铁磁谐振消除后,CPU作相应记录、存贮,并自动报警,显示有关谐振信息(包括发生时间、频率、幅值等)。如果是过电压或单相接地,CPU作出诊断后,装置分别给出显示和报警,并自动记录、存贮有关故障信息,最后CPU返回初始状态,并继续监测开口三角电压。
Working principle: This device uses the latest single chip processor of DSP as the core component to detect the PT open delta voltage(zero sequence voltage). When the voltage is less than 30V, the high-power harmonic elimination element in the device is blocked and has no effect on the system. When the voltage is greater than 30V, data acquisition of open delta voltage is started, and digital signal processing technologies such as digital measurement, filtering and amplification are used to analyze, calculate and judge the current fault state. If a ferroresonance occurs at a certain frequency, the CPU immediately starts the detuning circuit to make the ferroresonance disappear rapidly under strong damping. After the elimination of ferroresonance, the CPU records, stores and alarms automatically, displaying relevant resonance information (including occurrence time, frequency, amplitude, etc.). If it is overvoltage or single-phase grounding, after CPU diagnoses, the device gives display and alarm respectively, and automatically records and stores fault information. Finally, the CPU returns to the initial state and continues to monitor the open triangle voltage.
