7.2 kV, up to 120 MVA

The TMdrive-XL85 is a very high-power, medium voltage (7.2kV), AC fed drive designed for high-efficiency and power-friendly operation in a broad range of industrial applications. A single bank drive is rated for up to 30 MVA power level.

High reliability, low harmonic distortion, and high power factor operation are designed into the drive.

TMEIC’s water cooled design and compatibility of piping materials with de-ionized cooling system ensures that the drive has a MTBF of more than 20 years. 

TMdrive-XL85 Features and Benefits
Design Feature
Customer Benefit

Conservative design using 6000 V - 6000 A Gate Controlled Thyristors (GCT)

Highly reliable operation, expected 20-year drive MTBF

High energy efficiency approximately 98.6%

Considerable energy savings

Diode rectifier ensures power factor greater than 95% in the speed control range

Capacitors not required for power factor correction

36-pulse converter rectifier by using separated phase shifted transformer

No line-side harmonic filters required to provide lower harmonic distortion levels than IEEE-519 guidelines

5- level drive output waveform to the motor

Suitable for standard motors due to motor friendly wave form

Synchronous transfer to line option with no interruption to motor current

  • Allows starting control of multiple motors with one drive
  • No motor current or torque transients when the motor transitions to the AC line

 

Outdoor mounted input isolation transformer included in drive package

  • Less heat loss in drive room thereby reducing cooling HVAC costs
  • Less indoor space required
  • Simplifies design, installation and logistics
  • Ability to accept a wide range of industrial voltages such as 10/11/13.8/25/34/69 kV etc.

Up to 7.2 kV direct drive voltage output level

No output transformer required, and reduction in cable runs and size.

Deionized water cooling system

  • High efficiency cooling
  • Reduced fan and air conditioning load
