ABB frequency converters are a renowned brand developed, manufactured, and sold by the ABB Group. They are primarily used for controlling and regulating the speed of three-phase AC asynchronous motors. With their stable performance, rich combination functions, high-performance vector control technology, low-speed high-torque output, excellent dynamic characteristics, and superior overload capacity, they hold a significant position in the frequency converter market. ABB frequency converters are designed for industrial applications, particularly suitable for industrial process control fields such as paper, metal, mining, cement, power, chemical, oil, and natural gas industries. ABB frequency converters can be used not only as complete AC drive products but also as modular units to meet the requirements of users, OEMs , and system integrators. ABB frequency converters are highly flexible AC drive products; with certain configurations, they can meet various precise control needs of AC speed control systems in industrial fields. Below, the editor of China Transmission Network will introduce the classification of ABB frequency converters. Let's take a look!
ABB frequency converter classification
I. ABB frequency converters can be classified according to application type as follows:
1. Standard Frequency Converters. Standard frequency converters are simple to install, set up, and use, saving a significant amount of time. These converters have a user and workflow interface compatible with fieldbus systems, and their specifications, commissioning, and maintenance utilize common software tools and spare parts.
2. Frequency converters for fans and pumps. Frequency converters for fans and pumps are mainly used to drive fan and pump loads. Their main features are relatively light load and simple application functions.
3. Industrial frequency converters and combined frequency converters. Industrial frequency converters and combined frequency converters are mainly used in some large machinery and large engineering equipment. Their main characteristics are: complex functions, high performance requirements, strong expansion, communication, networking and other functions, and the ability to adapt to almost all industrial application conditions.
II. ABB frequency converters can be classified according to their installation method as follows:
1. Wall-mounted. Wall-mounted frequency inverters cover a power range up to 110kW , with all important features and options built-in (input-side reactor, EMC filter, brake chopper, etc.). All configurations are integrated and available in IP21 or IP55 packages. Wall-mounted frequency inverters are very compact, have a wide range of optional software, and are suitable for any industrial application.
2. Cabinet type. Cabinet-type frequency converters offer standard configurations suitable for any application, covering a power range up to 2800kW , with protection ratings of IP21 , IP22 , IP42 , IP54 , and IP54R .
III. ABB frequency converters can be classified according to their drive modules as follows:
1. Single Drive. A single drive inverter configuration integrates a rectifier bridge, DC unit, and inverter unit into a single AC drive unit. The single drive inverter is a complete AC speed control device that can be installed without any additional cabinets or enclosures. Single drive inverters are available in wall-mounted, floor-standing, or cabinet mounting options, and various protection ratings are available as options. ABB single drive inverters include the following models:
( 1 ) ABB-ACS150 series frequency converters are suitable for small general-purpose machinery with a power of 0.37 to 4kW .
( 2 ) ABB-ACS355 series frequency converters are suitable for small general-purpose machinery with a power of 0.37 to 7.5 kW .
( 3 ) ABB-ACS510 series frequency converters are suitable for fans and water pumps with a power of 0.75 to 110 kW .
( 4 ) ABB-ACS550 series frequency converters are suitable for medium-sized general machinery with a power of 0.75 to 110 kW .
( 5 ) ABB-ACS800 series frequency converters are general-purpose, with a power range of up to about 500kW (replacing the ACS600 series): among them, 04P is dedicated to fans and water pumps, and the others are used for general machinery.
2. Multi-drive. Multi-drive is a type of industrial drive product consisting of industrial drive modules connected to a common DC bus. The common DC bus provides DC voltage to the drive modules, which is supplied by a single rectifier unit in the unit. Rectifier units are available in a variety of options, ranging from simple diode rectifiers to complex active IGBT rectifiers. ABB's multi-drive series includes the following models:
( 1 ) ACS800 multi-drive frequency converter, power range: 1.5 ~ 5600kW .
( 2 ) ACS800 multi-drive module, power range: 1.5 ~ 2000kW .
IV. ABB frequency converters can be classified according to voltage level as follows:
1. Low-voltage frequency converters, with voltage levels of 380V , 480V , and 660V .
2. Medium-voltage frequency converter, with voltage levels of 1400V and 3300V .
3. High-voltage frequency converters, available in voltage levels of 6kV and 10kV and above.
The above is a detailed introduction to the classification of ABB frequency converters.
