The power supply system of passenger cars with an AC generator.

 

Purpose

 

Provision of low-voltage network of the car with continuous current voltage obtained by rectification of three-phase voltage of an AC generator having a capacity of 35 kVAr or three-phase voltage from an external power supply box.

 

Technical characteristics

• Value range of control voltage of direct current, V: 60...150
• Range of outgoing line three-phase feed voltage, V: 0… 150 
• Value range of output voltage of direct current, V: 0...150
• Crest value of outgoing current А: 25
• Rectification of input three-phase voltage
• Optical alarm about the delivery of input three-phase voltage
• Optical alarm and the issuance of a discrete signal for blocking inclusion YANV when you open its cover
• Optical alarm about emergency situations in external power supply box
• The issuance of a discrete signal for blocking car doors during train operation (at the generator frequency of more than 25 Hz)
• The issuance of a discrete signals in case of emergency:

- phase interruption of generator

- leakage resistance of generator windings on the cabinet less than 5 kilohms

• Current regulation of battery charge with mains supply of 380 V, 50 Hz
