Features

The control unit uses the current most advanced embedded operating system, using dual CPU core architecture, including general processing and system control ARM9 and powerful DSP, high-speed data processing, control and communication

The rapid algorithm with national patent technology (patent number: ZL200720037710.7) is used to make the circuit breaker have fast breaking capabilities. It can quickly isolate the fault line, solve the problem of fast isolation of distribution line failures, effectively avoiding the problem of cross-level trip

The capacitive voltage transformer (CVT) signal is received by a single-phase ground protection system having a national patent technology (patent number: ZL201020178325.6), and the online judgment of single-phase failure of small current grounding system is realized, and according to the set value Speaking police or trip action

The A / D module uses 16-bit A / D conversion and active low-pass filtering to make this product with extremely high measurement accuracy.

The communication method is flexible, supports GSM short messages, supports GPRS universal wireless services, supporting a variety of communication protocols

Using large-screen full-ritime liquid crystal display, display information, friendly interface, full Chinese system, parameter settings, fast

The temperature measurement and temperature correction technique is used, so that the product can be reliable and stable under different environmental conditions in all regions of the country.

The lightning protection module and special anti-interference measures can be used to test by strict electromagnetic compatibility (IV).
