        The fault recorder is a device that collects the data of electrical parameters during the normal operation of generator and main transformer, and can automatically record the waveform when the power system fails or vibrates. The fault recorder can record the whole process of electrical parameter change before and after the fault, and record the action of switching value, and remind the type, location and time of fault, which provides a strong guarantee for fault analysis and treatment in the later stage of power plant.

        The original fault recording of Handan hydropower station was put into operation in 2007 and has been put into operation for more than ten years. In recent years, the failure rate of the device has increased greatly, and the software and hardware can not guarantee the continuous reliable operation, and can not meet the new standards and requirements of State Grid Corporation for fault recorder, so it is necessary to upgrade the equipment.

        After repeated comparison, the power station chose to cooperate with Baoding smier Electric Co., Ltd., and selected our company's smr-dre3 fault recorder. The device can use mouse, keyboard and USB storage device, plus large screen display. The whole device is simple and fast to use.

        The fault recording screen adopts embedded hardware structure, which greatly improves the stability and reliability of the device. The recording unit adopts Linux operating system. This operating system has high security, strong reliability, faster use, and can avoid being attacked by malicious viruses. The smr-dre3 fault recorder is equipped with 32 analog signals and 64 switch signals. Of course, as a professional fault recorder manufacturer, it can expand the analog and switching values to 96 channels and 192 channels according to the needs of users.

        The operation of the upgraded smr-dre3 fault recorder is more simple, its reliability and stability are higher, and the data processing ability is also improved compared with the original fault recorder, which improves the learning efficiency of power plant personnel. Inspection personnel can judge whether the device is in normal operation through the status indicator on the front panel every day.
