Stepless speed regulation, relative to power frequency starting, has less impact on the power grid and equipment, extends the service life and maintenance cycle of the equipment, reduces the maintenance cost and downtime of the equipment. Monitor the load of the oil well in real time according to the load current of the pumping unit. When the oil and water situation changes, the system can automatically increase or decrease the number of strokes to improve system efficiency. Improve the power factor on the power grid side of the driver to prevent a small horse from pulling a big cart. The up and down strokes of the pumping unit in a working cycle are identified through the integrated cabinet. The up stroke is high frequency to lift oil, and the down stroke is slowed down at a low frequency to increase the crude oil production per unit time. In view of the special on-site use environment of the oil field, unmanned operation and remote monitoring, automatic power frequency conversion switching, ensure the stable operation of the product, and reduce the labor intensity of well inspection and parameter adjustment.

Comprehensive monitoring of key components and PCB temperature rise, rational design, and large thermal redundancy. Adopting the hardware platform of the new generation of IGBT and rectifier bridge, higher configuration, and large design margin. High and low temperature cycle testing, it can maintain stable operation in extreme environments and has strong environmental adaptability.

Steady speed accuracy: ±0.5% (SVC), ±0.02% (FVC); speed regulation range: 1:200 (SVC), 1:1000 (FVC); torque response: <40ms (SVC), <10ms (FVC).
