SAI-980 mainly used in 110kV and below the substation integrated automation system and its series products with finished completely true color display technology, man-machine interface is friendly, so you avoid the troubles find instructions. Each product is configured based on the interface of the PC debugging interface, combined with the specific analysis of the software package, greatly improved the field debugging tools. Products with dust, anti vibration design, suitable for installation in the switch cabinet and other environmental conditions are relatively poor field operation. Chassis panel using advanced industrial aesthetic design, easy to use, more cordial .Two..SAI-980 microcomputer protection features All types of protection functions are available, and can be customized according to user requirements. [multi channel state monitoring and logic definition function] device provides 13 open input, 12 way out of the volume, can be defined by the user. [measurement function] using 16 bit AD conversion chip, so that the measurement accuracy of 0.2; can measure the current voltage and the voltage current harmonic content, P, Q, power factor, frequency, calculation of electrical power, etc.. Large screen graphics color LCD display, using the Windows interface, dynamic display of a system diagram, a variety of electrical parameters and angle, vector and protection information. Chinese menu prompt, easy and convenient operation. [strong communication function] provides two RJ45 communication interface, RS485 communication interface and CAN port. Communication protocol supports Modbus, RTU IEC870-5-103 and other protocols. The communication parameters can be set up, which can realize the functions of remote measurement, remote control, remote control, setting and protection of setting and querying, working state of the device, SOE event recording, and recording data. The control circuit can be selected to meet the requirements of different application occasions without the two control loops with anti jump and anti jump. The powerful self checking function has the function of software and hardware real-time self checking and alarming, and can be positioned on the chip. [online programming function (ISP)] provides an online programming communication interface, can freely download all kinds of protection module, a system diagram, no need to disassemble the device. [SOE event record] online record of events of 1000, advanced first out (FIFO) dynamic refresh, with a time tag, power off is not lost. Event records are divided into "protective action records", "device alarm records", "SOE records", "device operation records" and "device operation records". Event log can be cleared. Fault recorder function can be the fault in the fault, the current, voltage, circuit breaker status and protection of information integrity of the record, for the user to provide a basis for fault analysis. Can record 10 - 4 recording **. When the protection action, the device automatically pop up the fault screen, the user is very intuitive to see the type of protection action. [telecontrol data simulation] and debugging system background, no need analog can be added on the device simulation of voltage, current, power, frequency, switching, protection action marks and SOE events. [GPS clock synchronization interface to provide clock synchronization, receive GPS school time **. Users can set the user can according to their own requirements to set the password, no password can not modify the parameters of the device, you can only view the data. The chassis is made of profile, compact structure, strong vibration resistance and electromagnetic compatibility.
