Smart capacitor cabinet OVE600 adopts the modular design idea, each smart capacitor in the smart capacitor cabinet can be 

networked with each other, but also as an independent operation device, in line with the requirements of intelligence, 

miniaturization, high performance and safety performance, high reliability, pay attention to environmental protection, etc., 

so that the maintenance of the smart capacitor cabinet is very simple and has a cost-effective advantage.

OVE600 series smart capacitor cabinet is designed for the power network harmonic content is large, ordinary power capacitors

 can not operate normally, it uses special technology and process, by linear series electrical appliances and industrial 

low-voltage power capacitor combination, so this product is mainly used in harmonic serious places, capacitors can operate

 reliably, The capacitor will not overheat, the insulating medium will not age, the self-healing performance will not decrease, 

and the service life will not be reduced.

Main function

1. Filter function

In the case of harmonics in the user's load, it can filter out the interference of harmonics to the user, eliminate the amplification

 effect of capacitors on harmonics, eliminate resonance, reduce and limit harmonic current and flicker current, protect 

equipment, and compensate reactive power.

2. Measurement

Distribution voltage, current, reactive power, power factor measurement; CT phase and ratio automatic measurement and

 correction; Measurement of three-phase current and internal temperature of each capacitor.

3. Protection

Circuit current cutting and overcurrent protection; Capacitor overvoltage, undervoltage protection; Capacitor overtemperature,

 phase break, three-phase unbalance protection.

4. Signal number

Capacitor switching state, over and under state, over and under voltage state signal; Protection action type, self-diagnosis fault

 type signal.

5, fast casting

The minimum capacitor switching time can be set for 1S.

6. Communication

CAN communication is used between the intelligent capacitor and the controller, which is easy to upload a large amount of 

sampled data and exchange information with the peripheral monitoring terminal, and easy to integrate the system.

7, intelligent network control

It can automatically detect and track the reactive power change of the system, and automatically switch the capacitor bank. 

Capacitors with the same capacity are switched on according to the principle of cycle switching, capacitors with different 

capacities are switched on according to the principle of suitable complement. Capacitor first return, first return first investment;

 The capacitor with low operating temperature is cast first, and the capacitor with high operating temperature is withdrawn 

first. When the compensation condition is constant, the capacitor is switched on and off every 15 minutes to avoid a single 

capacitor being put into operation for a long time.
