KR-3000Introduction to Series Measurement and Control Devices

●The KR-3000 series measurement and control device comprehensively considers the requirements of substations for data acquisition and processing, and uses computer technology to achieve functions such as data acquisition, control, and signaling.

This device fully complies with the design requirements of distributed systems, comprehensively analyzes the information collection requirements of substations, installs small and highly reliable unit measurement and control devices at the information source points, and connects with the central equipment installed in the control room through on-site measurement and control networks to achieve monitoring of the entire substation.

●In addition to completing routine data collection, this series of devices can also achieve rich measurement, recording, monitoring, and control functions, replacing other conventional specialized measuring instruments. Therefore, this system fully meets the requirements for comprehensive automation and unmanned operation of substations of various voltage levels. The safety of device operation was fully considered during the design process.

●The various interlocks in the control system, the setting of open control circuits, the selection of high reliability connecting components, the application of fieldbus communication technology, and the use of new relays enable the device to operate more safely and reliably.
