CL200 Series Four-Quadrant Inverter

Product Features

01 Powerful function
Stepless speed regulation, relative power frequency start-up, small impact on the power grid and equipment, extend the service life and maintenance cycle of the equipment, reduce the maintenance cost and downtime of the equipment;

Monitor the load of the well in real time according to the load current of the pumping unit. When the condition of the well changes, the system can automatically increase or decrease the number of strokes to improve the system efficiency;

Increase the power factor on the grid side of the drive to prevent small horse-drawn carts;

Identify the up and down strokes of the pumping unit in a working cycle through the integrated cabinet, and increase the crude oil production per unit time by high frequency oil extraction in the upper stroke and low frequency slowdown in the lower stroke;

For the special use environment of the oilfield site, unattended and remote monitoring, self-actuated frequency conversion switching, to ensure the stable operation of the product, while reducing the labor intensity of well patrol parameters.

02 High reliability
Long-Life Technology
Comprehensive monitoring of key components and PCB temperature rise, rational design, and high thermal redundancy.

New generation device platform with large design margin
Adopting a new generation of IGBT and rectifier bridge hardware platform, higher configuration, and large design margin.

Severe high and low temperature environment testing
High and low temperature cycle testing, able to maintain stable operation in extreme environments, with strong environmental adaptability.

Advanced three proof paint process design
The machine can import different three proof paint processes according to the model and specifications of the single board, ensuring the uniformity of the products three proof process and batch consistency.

03 Excellent performance

• Stable speed accuracy: ± 0.5% (SVC), ± 0.02% (FVC);
• Speed regulation range: 1:200 (SVC), 1:1000 (FVC)
• Torque response: < 40ms (SVC), < 10ms (FVC);
• In closed-loop vector mode, the torque linearity deviation is within 3%. Stable torque output, high low-frequency torque, and convenient switching between torque mode and speed mode;
• Supporting multiple PG cards, supporting various encoder interfaces such as collector signals, differential signals, and rotary signals, facilitating closed-loop vector control;
• Capable of automatically identifying asynchronous induction motors and achieving high-performance vector control; Can achieve accurate setting of motor parameters for long-distance power cables under load conditions; Can automatically distinguish the direction of encoder signals under encoder conditions, simplifying the debugging process.
