The OSLBK series of Auto-Compensating Switchboard for PCP studied by Dongying Orientsun Electric Company Ltd., adopts the electronic technology to sample the voltage and current in real time, and then input these sample data to SCM. Compared these data to the setting value, it will calculate the reactive compensation value, control the group number of capacitance to the electric network automatically, and accomplish compensating the reactive power of the system. Based on the results, it can save 4% active power. (Different oil well with different power-saving effects)
1. Utilize the step-by-step calculation switching, with high accuracy of compensation and anti-interference performance.
2. Track the change of reactive power with high speed dynamically.
3. Protect the unit from overload, under load, default phase, short circuit, three phase current unbalance, pump-off, rod-broken etc.
