<p>The invention relates to an independent installation to ensure keeping warm the traction diesel engine, the accumulator battery and locomotive driver's cab and economic operation of the diesel locomotive. The installation operates independently of the other energy sources available on the locomotive and out of this has two modes of operation - manual and automatic - with the ability to record all data transmitting them to a central dispatcher. The installation, according to the invention, comprises the coolant circuit of the traction diesel engine (1), which can be common with the cooling circuit of the auxiliary diesel engine (9), the group of radiators (2), an auxiliary pump for circulation of coolant (3), an electric or thermal heater (4) and a temperature sensor of the coolant (5) which controls the starting-off of the independent power source within the minimum-maximum coolant temperature when the locomotive is long stationary or in the shed (Figure 1). The independent installation to keeping warm the locomotive diesel engine, according to the invention, comprising an auxiliary diesel engine group (9), three-phase synchronous generator (10) which feeds an auxiliary pump (3), an electric or thermal heater (4), and for charging the accumulator battery (11) and for supply other power circuits (6) of the locomotive is used a voltage adapter (7). Another voltage adapter (8) supplies the water pump from the accumulator battery when the locomotive is long stationary or in the shed and the auxiliary diesel engine is stopped (Figure 2). The independent installation to keeping warm the locomotive diesel engine according to the invention, operates also in automatic mode using the temperature sensors and adapters (14), a PLC (programmable logic controller) for control and monitoring of the operation, (15), electric execution devices ( 16), recording device and display (12) and the communication system to a central dispatcher (13)(Figure 3).</p> |
