COOLING SYSTEM INVERTER
The converter KL-7500 supplies the cooling system
of the railway coaches. The input voltage is the down transformed heating
voltage. It has two AC output voltages with common potential. One phase
output is for the air ventilation of the cooling system and three phases
output is for the compressor motor. The start of the last one is soft
start.
The converter consists of input rectifier, booster stage, one and three
phases inverters supplied by the intermediate DC voltage. The converter
has a microprocessor control, a data logging and measuring system which
operates as a dual digital storage oscilloscope too.
The equipment is mounted in an open frame put in the box fixed to the
under frame. The box is ventilated by the cooled air of the cooling system.
