ABB ACS 1000i reliable power control
ABB ACS 1000i reliable power control
DESCRIPTION
The ACS 1000 family of drives, one of the most successful variable speed drives in its class, provides simple and reliable power control.
Power control of induction motors
Drawing from over a century of industrial manufacturing experience, ABB provides a simple and reliable approach to power control: the ACS 1000 family of drives for speed and torque control of 315 to 5000 kW induction motors for voltages of 2.3, 3.3, 4.0 and 4.16 kV. It is available with air or water cooling.The air cooled drive can be supplied with separate input transformer (ACS 1000) or as a fully integrated drive (ACS 1000i) which includes input transformer and, optionally, input contactor.
Operational experience
With over one thousand installations worldwide, the ACS 1000 family is one of the most successful variable speed drives in its class. Since its introduction in 1997, it has set the benchmark for reliable and efficient control of medium voltage applications such as pumps, fans, conveyors, extruders and compressors.
Key product features
– Retrofit-ready for existing motors and suitable for most medium voltage applications
– Output sine filter for pure sinusoidal voltage and current output: standard motors, no motor derating, no voltage stress and no common mode voltages on the motor insulation
– Fuseless design for reliable, non-aging, maintenance-free circuit protection
– DTC control platform for exceptionally high torque and speed control performance
– Integrated or separate input transformer for highest system design flexibility
Network friendly
Depending on the network conditions, the drives of the ACS 1000 family can be equipped with a 12- or 24-pulse diode rectifier which meets the stringent requirements for current and voltage harmonic distortion as defined by IEEE, IEC and EN. This eliminates the need for costly harmonic analysis or installation of network filters when applying a new drive.
Output sine filter – perfect for standard motors and retrofit applications
Voltage reflections and common mode voltages, caused by any inverter topology, are a real concern for medium voltage motors. They cause excessive stress to a standard motor insulation and create harmful bearing currents, both with potentially disastrous consequences. Furthermore, the motor is subjected to additional harmonic heating generated by the inverter switching if no further precautions are taken.With an ACS 1000 or ACS 1000i, all these detrimental effects are totally eliminated by its unique output sine filter, being an integral part of the drive. The result is an excellent waveform of voltage and current, supplied to the motor.
Benefits
– Compatibility with standard induction motors without derating
– Ability to retrofit to existing motors
– Motor efficiency same as Direct-On-Line (DOL) operation
– Reduced motor noise
– Use of standard cables
– No limitation of motor cable length
System design flexibility
The ACS 1000 family can be configured with either an integrated dry-type or separately installed input transformer. This flexibility enables the use of oil-filled transformers when the transformer will be mounted outdoors. The advantage is that heat losses from the input transformer are not dissipated in the electrical room. The integrated input transformer, on the other hand, simplifies installation and commissioning (three cables in - three cables out).
