The SINAMICS PERFECT HARMONY GH180 is a series of cells linked together to create the medium voltage power output of the drive system. The design features an integrated transformer and the ability to scale the drive for a wide range of voltage and output power. The drive offers increased availability due to its modular design and ability to bypass any one cell during operation. The quality of the output voltage is so close to perfect sine-wave shape that motors of literally any type – old or new, low-speed or high-speed – can be operated without any additional stress.
Extremely motor friendly as a result of an almost sinusoidal output wave form
Higher reliability due to the drives’ cell bypass capabilities which keeps the drive and your application running even in the event of a cell failure.
Higher availability due to the drives’ cell redundancy and cell bypass features.
Maintenance and process friendly due to faulted cells being replaceable at your next available maintenance period.
Very small footprint with an integrated air or water cooled transformer.
Able to support long cable applications in excess of several kilometers.
Output voltage range:
2.3 to 11 kV
Power Range: 0.18 to 24.4 MVA (0.2 HP to 28000 HP)
Air-cooled drives up to 10 MW
Water-cooled drives up to 20 MW
Max. output frequency:
330 Hz standard
Open / closed loop control:
- sensorless vector control (optionally with sensor)
- communication with all current BUS systems
- automatic motor identification
- automatic start-up
Degree of protection:
IP21 or higher, air cooling; IP31 (excluding blower cage)
IP43 or IP54 water cooling
Rules and standards:
ANSI, NEMA, UL, CSA, CE
No output transformer required – motor voltage 2.3 to 11 kV can be provided directly.
No harmonic line filters or power factor compensation required.
The cell bypass option ensures automatic bypass of a failed power cell in typically 250 milliseconds or less (less than 1/2 of a second).
The ProToPS option provides a hierarchical system of warnings instead of tripping the drive and automatically shutting down the system due to a malfunction. This control strategy allows time to evaluate the situation and respond appropriately to avoid a system shutdown.
No common mode motor insulation stress – the drive includes an integral isolation transformer.
Compatible with both new and existing induction or synchronous motors from any manufacturer without any special design considerations.
No significant drive-induced torque pulsations – even at low speeds.
The drive is able to ride through voltage dips or power outages.
For fiber industries – the drive can provide high output voltage at low power.
Commonly found on pumps, fans and compressors in the Oil & Gas industry. Capable of supporting electrical submersible pumps (ESP) and other long cable applications, as well as supporting LNG and high speed applications.
Frequently used in medium voltage pump, fan, and compressor applications. Also able to supports mixers and extruders in the chemical and petrochemical industries.
Used in numerous pump and fan applications in the power generation industry, such as ID Fans, FD Fans, coolant pumps and boiler feed pumps. Our water-cooled drive is the only converter approved for use on nuclear power plants due to its high availability and redundant operational components.
Utilized in several mining applications such as slurry pumps, uphill conveyors, crushers, vertical mills, VertiMills, select horizontal mills and standard mining pumps and fans.
Able to support applications such as vertical mills, crushers, kiln drives and standard cement fans and blowers.
Commonly supports metals applications such as basic rolling mills, sinter fans, de-dusting fans, de-scaling pumps, and other standard pumps and fans.
Within the water and wastewater industry this drive will mainly support pumps and fans in the several different types of water plants such as desalination, drinking water and wastewater, as well as assisting with water transport & pipeline networks.
Capable of supporting most medium voltage drive system retrofit projects, for applications such as pumps, fans, and compressors.
The new medium-voltage converters allow for speed-controlled operation of fans and eliminate the previously used damper for flow control.
Working in partnership with Russian companies, Siemens supports the country in its ambitious economic and technical modernization.
