The Solution for Rail transportation field

The Solution for Rail transportation field

  With the rapid development of semiconductor technology, the modern advanced urban subway, light rail vehicle traction control system and auxiliary power supply system are all used the VVVF frequency modulation mode of the traction inverter voltage regulator and the auxiliary inverter of CVCF. Tac and main pay - direct - drive locomotives, current sensor and voltage sensor are also widely used in the system of DC and AC circuits which is to realize the closed loop control of the whole system.In the urban rail transit vehicle air conditioning system, sensors are often used to match the electronic thermostat for temperature control.Thermostat often use electronic regulator and sensors are used for temperature detection, generally it will use thermocouple or thermistor sensor.
