Intelligent fast harmonic suppression reactive power compensation device

Product Description

NA series intelligent integrated fast harmonic suppression reactive power compensation device is a product that combines the characteristics of anti-harmonic and fast reactive power compensation. It is designed for the environment where the power network has large harmonics, rapid reactive power changes, and ordinary power capacitors cannot operate normally. It uses special technology and craftsmanship. It is composed of circuit breaker, thyristor, reactor and filter type low voltage power capacitor. With fast response speed, capacitor zero-crossing switching, no...More

Performance Characteristics

● The use of new electronic switch technology and control algorithms can meet the rapid response requirements of reactive power compensation. Compared with ordinary smart capacitors, it has fast response speed, short switching intervals and long switch life.
● Realize switch voltage zero crossing input, current zero crossing removal, closing without inrush current, no arcing and reignition.
● With over-current, over-temperature self-protection function, realize the three-phase separate phase-out protection function, and control... More

The Main Function

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.

Specification Model

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.
