The development of the brand introduced ac inverter to control the speed and torque of the standard induction motor, abb inverter
The standard induction motor is the main equipment in the industrial field. ABB is the market leader in the field of global frequency conversion controllers and motors. Ac frequency conversion technolog
y extends the speed range of the motor - from zero to far above the rated speed - so that the production efficiency of the drive process is significantly improved. In the case of a low capacity, the converter saves energy by reducing the motor speed. [1] ABB standard frequency converter is simple to purchase, install, set up and use, saving a lot of time. They are widely available at ABB's distributors and are thus called standard frequency converters. This type of converter has a common customer and process interface with the fieldbus, specification design, debugging and maintenance of common software tools, and general spare parts. Edit this section common type ACS 2000
Air cooling type ACS 2000 inverter in cement, mining and mining, metallurgy, pulp and paper, water, electricity and chemical
industry, petroleum and natural gas industries such as fan, pump, compressor and other public application. ACS 2000 frequency converter combined with innovative technology, in order to cope with the challenge of the industry, such as the flexible power supply connection, lower harmonic, reducing energy consumption, static reactive power compensation as well as the need of installation and debugging. Flexible power supply connection ACS 2000 frequency converter can not use input isolation transformer, depending on the user's choice and the situation of the existing equipment, thus allowing direct connection to the power supply (direct grid connection), or can be connected to a
n input isolation transformer. Under the direct power grid connection configuration, users can benefit from lower investment costs because they do not need a transformer and can save a large amount of investment. ACS 2000 inverter compact structure, lighter weight, and lower transportation costs compared with other inverters that require transformers, and require less space in the electrical room. From the compact design, the ACS 2000, which connects directly to the 6.0-6.9 kV power grid, is applicable to the modified project of the standard induction motor for speed control. In need to match or voltage power supply for electrical isolation of applications, the input transformer is needed, the ACS 2000 frequency converter can be connected to the conventional double winding oil-immersed or dry input isolation transformer. Lower harmonic integrated the technologies of active front-end (AFE), without using expensive, special transformer, power grid side harmonic can be minimized, and four quadrant operation as well as the additional benefits of reactive power compensation. The AFE provides low harmonics and satisfies the requirements of
current and voltage harmonics in various standards. Thus, there is no need for harmonic analysis or installation of mesh side filters. In order to minimize energy consumption, the AFE allows four quadrants to operate and return the braking energy back to the grid. Reactive power compensation AFE can also provide reactive power compensation. With static reactive power compensation, the s
service faultmooth power grid voltage can be maintained and no reactive power penalty can be avoided. Installation, debugging and operation and maintenance are convenient for the installation and commissioning of the installation and debugging. Install a converter,
Using ABB's simple concept of "three to three" wiring, simply disconnect the cable running directly from the network, connect to the converter, and then connect the converter to the motor. The ACS 2000 design has an extractive phase module to facilitate quick replacement of all frequency converter components from the front, and the average maintenance time (MTTR) is the industry-leading level. High reliability The converter using the validated multilevel voltage source inverter (VSI) topology structure, mature high voltage IGBT power semiconductor technology and direct torque control (DTC) motor control platform, so it is of high reliability, extend the MTBF (MTBF) and increases the utilization. The ACS 2000 inherited the VSI topology structure of the ABB and adopted the patented, multilevel design based on IGBT, provides approximate sine wave current and voltage waveform, makes the inverter is compatible with standard motor and cable. The ACS 2000 converter control platform USES ABB's highly acclaimed DTC platform, which provides the maximum torque and speed performance and minimal loss of the medium voltage ac converter. Under all conditions,
the control of inverter is fast and smooth. Lower total cost of investment and flexible power supply co
nnection, lower harmonic and energy consumption, ease of installation and debugging and higher reliability, makes the ACS 2000 throughout the life cycle with low total cost of investment. [2]
