1. The protection and control system adopts advanced high-precision data processing and programmable controller protector with advanced protection algorithm, which has the advantages of high protection accuracy,fast response speed, high degree of inteigence, stable performance,diverse control methods and reliable action.
2. This series of products adopts permanent magnet vacuum circuit breaker to close and open the main circuit, including electric closing, electric opening, manual closing and manual opening, with long service life, less maintenance and reliable operation.
3. Full protection functions, including overload, shor circuit, undervltage, overvoltage, transformer temperature detection, phase imbalance.lowvoltage side fault, remote control and other functions.
4. Backlit LCD display is used to display the working status, parameters and fault types of the switch. With menu-type human-computer interface,the operation is intuitive and simple.
5. All protection function parameters can be adjusted through menu selection, with wide application range and high protection accuracy.
6. Analog signal processing is digital signal. With strong anti-intererence ability, simple wiring, arge amount of information. reliable control and other characteristics.
7. It has the "memory' function, and all the protection function parameters adjusted each time are memorized and saved. The last set parameter wil be automatically extracted when the next power transmission or system reset, and the protector can also remember the current fault information.
8. Equipped with RS-485 communication interface, it can communicate with the upper computer.
