Electric power departments and users are troubled by the malignant accidents of burning or even explosion of voltage transformer due to ferromagnetic resonance. The smr-wx series microcomputer harmonic elimination device developed by our company uses high-performance single chip microcomputer as the core component of detection and control. It has the advantages of fast operation, stable performance and strong anti-interference ability. It is a solid state relay with reliable action and not easy to be damaged. It solves the problem that the resistance is easy to be damaged in case of high current.

The intelligent microcomputer harmonic elimination device can display the system clock in real time, and can display the total voltage and main vibration frequency of Pt opening of 1 ~ 4 sections of bus through key operation. It can distinguish ferromagnetic resonance, grounding and overvoltage.

The microcomputer harmonic elimination adopts advanced high-speed ARM chip and CMOS industrial chip from abroad, with unique design, electromagnetic shielding, software and hardware redundancy, fast operation speed, strong anti-interference ability and low power consumption.

In terms of chip selection, our company chooses ARM chip and CMOS industrial chip, which are small in size, low in power consumption, low in cost and high in performance, with faster instruction execution speed and high execution efficiency. By using this chip, the cost of the whole system is reduced, thus the price of the microcomputer harmonic elimination device is reduced, and the products are more easily accepted by consumers.
