保定电气厂

电力部门和用户由于铁磁谐振而时常发生的电压互感器（PT）烧毁甚至爆炸的恶性事故，针对这一问题，我公司研制开发了AWZX系列微机消谐装置。本装置使用ARM嵌入式工控系统和大功率、无触点元件消谐，运算速度快，性能稳定，抗干扰能力强，动作可靠的同时，解决了使用电阻在大电流时易损坏的缺点。本装置可以消除铁磁谐振，还可以区分过电压，单相接地故障。

Electric power department and users frequent by ferromagnetic resonance voltage transformer (PT) burning explosion even malignant accidents, in order to solve this problem, our company developed the AWZX series harmonic elimination device of a microcomputer. This device using ARM embedded industrial control system and high power harmonic elimination, non-contact component, computing speed is fast, stable performance, strong anti-interference ability, reliable operation at the same time, solved using resistance in the large current when the shortcoming of easily damaged. This device can eliminate ferroresonance, can also distinguish between overvoltage, single-phase earth fault. 

装置特点

Device characteristics 

适用于35kV以下各种电压等级，多个谐振频率(1/3分频、1/2分频、工频、3倍频)均适用；

Used in the below 35 kv voltage grade, multiple resonance frequency (1/3, 1/2 frequency, power frequency, frequency three times) all applicable; 

无需整定和调试，开机自检后自动进入运行状态，设备维护量低；

Without setting and debugging, boot after self-checking automatically enter the running state, the equipment maintenance cost is low;
