Triol AT27 VFD ED line Design and Construction
The design is a multi-winding phase-shift transformer with connection to the supply power cells of the electric motor which is the primary drive unit.
The roof-mounted cooling fans can be removed for easy transportation. The unified design of VFD cabinets allows for on-site assembly and installation. And also the control system compartment has a reliable, versatile design.
Triol AT27 VFD ED line Cooling System
The AT27 VFD ED is equipped with a forced-air cooling system. The exhaust fans are mounted on the roof of the unit and the speed of the fans is software controlled and optimized according to the temperature of the phase shifting multi-winding transformer and the IGBT in the power element.
Another important feature is the air filter and its location. Air filters are installed in the cabinet doors to prevent dust accumulation and thus air contamination is removed before it enters the cabinet. The filters can be removed and replaced during operation without affecting the safety of the operating personnel.
