جهاز متكامل KC500 للحماية الذكية والقياس والتحكم

OVerview

KC500 is an integrated intelligent protection, measurement and control device independently developed by Ningxia Kaichen Electric Group Co., Ltd. Products are widely used in electric power, petrochemical, steel, metallurgy, public and civil construction, communications and water conservancy industries. It is suitable for power transmission and distribution systems with voltage levels below 35 kV.

 

Features

◆Fully sealed structure with good shock resistance and dustproof performance

◆Miniaturized design, small size, light weight, beautiful appearance, easy installation

◆Unique reliability design, no adjustable components, good device stability and strong anti-interference

◆Fully Chinese touch screen display, clear and easy-to-understand man-machine interface, and overall operation is extremely convenient

◆The power supply of the device is both AC and DC, and the operating power of the device is DC220V or AC220V

◆With RS485 bus serial communication port, and integrated MODBUS standard communication protocol

◆With event sequence recording function, it can record 150 events, and the data will not be lost after power failure

◆It has a complete self-check function, complete exception records, event records, operation records, and all information is maintained when power is off

◆The appearance is small and exquisite, the structure is reasonable, the use of high-grade, high-quality components and multilayer board technology and SMT technology, so that the product has high electrical performance

◆The internal integrated zero sequence current (voltage) synthesis algorithm can add zero sequence PT (CT) or not add zero sequence CT (PT) to achieve zero sequence overcurrent voltage protection

◆Has a complete circuit breaker operating circuit

◆Split mechanism design with intelligent protection measurement and control module

◆The protection, measurement and control system and the human-computer interaction system are interconnected on the first line, the wiring is simpler and the design is simpler

◆The protection measurement and control system adopts high-performance ARM chip, the protection measurement and control function is more reliable, and the fault judgment is faster

◆The human-computer interaction system adopts the ARM COTEX-A series of high-speed CPU chips, the human-computer interaction function is more complete, simpler and more efficient

◆With the cloud platform upload monitoring function, it can be connected to the monitoring cloud platform to carry out all-round early warning and protection of the monitored power system

◆With voice prompt function, prevent wrong operation, and carry out safety alarm

◆With proximity sensor function, realize product intelligence
