Intelligenter integrierter Stromkondensator | 400Vac | CJAD
Intelligent monitoring system
Acquisition of current, Stromspannung, Verlassen Sie sich auf die 32-Bit-Plug-in-MCU von ST America, die eine schnelle Probenahme durchführen kann, Die Übertragungszeit von 12-Bit-AD benötigt nur 1uS, Diese können eine hochgenaue Messung und Berechnung des 3-P-Stroms realisieren, 3-P-Spannung, 3-P Wirkleistung, Blindleistung, transparent power and etc, calculation and analysis of harmonics
HMI system
Monitor is LCD with 128X64 matrix, Chinese language, display the time, inside temperature, aktuell, Stromspannung, harmonic parameters at real time, check other parameters, operation status through keys, also the values of over-voltage, under- Stromspannung, under-current, Übertemperatur, over-compensation can be set and saved, data not lost in case of power failure.
Intelligent connection with power system
The product provides RS485 port, built-in MODBUS-RTU protocol, compatible with DL645-2007 protocol, able to perform remote monitoring and controlling. When more than one product connected with system, they will have one master machine among them automatically, others as slave machines, become automatic control system of reactive power compensation, any of individual one has fault, it will stop running, does not influence on others operating; if the master machine has fault and out of operation, they will produce new master machine automatically, form a new system.
Power capacitor
Hi-performance dry type cylinder-shaped self-healing power capacity, has the merits of well radiation, kleine Größe, long service life, ensure the safety and reliability.
Fused disconnector
The general switch cooperated with high breaking fused disconnector is able to break 120KA short circuit current, large break position, to ensure the product able to isolate from system quickly and safely.
