ROLLING STAFF PULSE INVERTER COOLING COOLING SYSTEM

摘要

Cooling system of a pulse inverter, consisting of three phase elements of an insulated gate bipolar transistor and forming a three-phase voltage system with variable voltage and frequency parameters at the output terminals to power the traction motor of the rolling stock, containing a liquid cooling block of the inverter, which houses temperature and pressure control sensors cooling liquid, installed in communication with an inverter control means configured to limit the power or block the pulse inverter in case of exceeding the temperature and / or pressure of the cooling liquid, the system is configured to control and adjust the input pressure of the cooling liquid.
