ABB ACS1000 medium voltage drive
ABB ACS1000 drives are medium voltage frequency inverters designed to control the motor speed and torque in the power range from 315 to 5000 kW and with voltages up to 4.16 kV.
ACS1000 main series
ABB company produces three types of such drives:
- ACS1000 air cooled.
- ACS1000 water cooled.
- ACS1000i with air cooling.
The first and second types are created with a separate input transformer, and the third with an integrated one. Let's look in details.
Air-cooled ABB ACS 1000 is a drive with separate input transformer, for operation with asynchronous motors power up to 2000kW. Almost any medium voltage network can be connected to the primary transformer winding.
Its design has a 12 pulse input bridge. The degree of enclosure protection is available in several versions: IP21, IP22, IP31, IP32, IP42. Design with separate transformer reduces air conditioning requirements for customer.
Water-cooled ABB ACS 1000 as well as the previous model has a separate output transformer and designed to work with motors that have a power up to 5 MW. Input bridge in the standard version has 12 pulses, but it is possible to install 24 pulses one on request. The efficiency of equipment is more than 98%.
Device can work in almost any medium voltage network with frequency of 50 or 60 Hz. The enclosure protection level is IP31 or IP54, depending on the product version. Heat losses from a separate transformer are not dissipated in the room.
ACS1000i is a frequency converter with built-in input transformer. It is also possible to install input contactor as additional option. Integrated transformer provides quick drive commissioning. Inverter construction has an air-cooling technology system.
The drive can control asynchronous electric motors, which have a power up to 2000 kW. Such equipment can operate with voltages up to 7.2 kV. It is possible to have higher value up to 11kV. Frequency converter is equipped with 24 pulse input bridges.
Drive housing have IP21 or IP42 protection. Its performance efficiency can be more than 98%.
MV ACS1000 Industrial application areas
Presented inverter series are designed to service asynchronous motors without their power reduction. Devices can also work with medium voltage systems in other industrial automation applications.
Most often abb acs1000 / 1000i are used in:
- ventilation systems;
- pump systems;
They can work in cement, chemical, paper, mining areas where such equipment is used.
Medium voltage drives use standard cables without length limit. It also has the possibility of operating with different global network protocols (Profibus, Modbus, Allen-Bradley, DeviceNet, Ethernet, ABB advent Fieldbus). Such advantages provide a wide range of mounting options.
