1, introduction:

No reactive power dynamic compensation is the fuzzy control technology and single-chip microcomputer technology and electronic precision measuring technology advanced combined, according to a given power factor and voltage, the real-time measurement of the current and active power, timely dynamic compensation.The main circuit components using high power electronic devices do not contact switch, fast response, the response time is 20ms, the frequent change of load, does not appear excessive compensation and lack of compensation, the power factor of the system can reach 0.97.The consideration of adaptation to the harsh electromagnetic environment, the anti-interference measures taken by the unique, to ensure the device can run reliably for a long time.Dynamic wattless compensation device can effectively filter the harmonic voltage and current, the regression of sine wave, improve the consumption environment, and to provide capacitive wattless power, improve power factor.

2, characteristics:

(L) using contactless automatic switching, continuous frequent switching filter group without affecting the switch and capacitor life.

(2) the rapid detection system, rapid, real-time compensation according to no power needed by the system.

(3) the LCD real-time display system voltage, power factor, input system filter group number, the compensation current data.

(4) special design according to customer system, filtering effect is obvious, the compensated power factor of not less than 0.95.

(5) dynamic fast response time, response time of less than 20ms.

(6) the switch without transient impact, no inrush current, no arc reignition, no need to discharge can be cast.

(7) complete protection function, with overvoltage, undervoltage, overcurrent, overheating protection, high reliability.

(8) a small amount of maintenance, low operation cost.
