Интелигентен интегриран кондензатор за мощност | 400Ваку | Cjad
Intelligent monitoring system
Acquisition of current, напрежение, разчитайте на 32-битов MCU тип plug-in, произведен от ST America, които могат да извършват бързо вземане на проби, времето за прехвърляне на 12-битов AD изисква само 1uS, те могат да реализират високоточно измерване и изчисляване на 3-P ток, 3-P напрежение, 3-P активна мощност, реактивна мощност, transparent power and etc, calculation and analysis of harmonics
HMI system
Monitor is LCD with 128X64 matrix, Chinese language, display the time, inside temperature, ток, напрежение, harmonic parameters at real time, check other parameters, operation status through keys, also the values of over-voltage, под- напрежение, под ток, над температура, 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, вграден протокол MODBUS-RTU, 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, малък размер, дълъг експлоатационен живот, 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.
