The intelligent integrated fast harmonic suppression
reactive power compensation device has the main function of the aforementioned
anti-harmonic low-voltage intelligent power capacitor, and also has the function
of fast control.
(1) Networking function: support bus mode and level mode connection. Using the bus mode, the device and the controller realize intelligent networking, support dynamic join and exit, real-time data query, parameter setting and action execution and other operations. In the level mode, the device level control terminal is connected to the controller for direct control.
(2)Switching function: receiving the switching command of the bus or level mode, and switching according to the working state of the device itself (not in the blocking and fault state).
(3) Measurement function: Measure the internal three-phase compensation current as the basis for judging the capacitor compensation current overcurrent.
(4) Protection function: short circuit protection, over current protection, phase loss protection, over temperature protection, switch failure prompt.
(5) Man-machine interface: indicator light: power light, switching indicator light, dial switch, setting debugging/working status, plastic case circuit breaker operation port, used for opening and closing devices.
When in use, it is equipped with NA-9 series
integrated measurement and control device. The 0.4kV grid voltage level uses
JKWNA-909, and the 0.66kV grid voltage level uses JKWNA-910.
