High-voltage electric heaters for the systems of liquid heating of passenger cars are devices intended for heating passenger car parks in the cold season.
Comfort of travel of passengers in passenger carriages of locomotive traction having a liquid heating system at negative temperatures of outside air directly from envy from a hot-water boiler. When a high-voltage main line of 3000 V is connected to the car, the heating of the car is carried out by a hot-water boiler, in which high-voltage heaters (heaters) are installed, which heat the water to 950С for the heating system. The automation system by turning the heating system on and off maintains a comfortable temperature inside the passenger car.
