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

 

Purpose

 

Provision of power supply system of a passenger car with electric power from an external three-phase network of 380 V, 50 Hz for long-term parking.

 

Provides:

• lowering of the input voltage three-phase network 380 V
• remote disconnection YAVP from the external network 
• optical alarm about the delivery of the external voltage mains supply to YAVP 
• optical alarm, the issuance of a discrete signal and the output voltage removal of YAVP in emergency situations:

- open-phase fault of external mains supply 
- circuit discontinuity of the primary side of the main transformer YAVP;
- circuit discontinuity of the secondary side of the main transformer YAVP or circuits which connect YAVP with low-voltage box
- open access to power circuits of a low-voltage box;
- leakage resistance between the windings of the power transformer YAVP less than 5 kilohms
