Abstract

The invention discloses a switching control method for hybrid power sources of railway engineering machinery. The hybrid power sources comprise a catenary power supply module and an internal combustion power supply module, electrical power from the catenary power supply module or the internal combustion power supply module is converted and processed by a converter and then converted into electricpower required by a traction motor. When a catenary is electrically connected and power is continuously supplied to the catenary, the power is supplied to the traction motor through the catenary powersupply module. When the catenary is not electrically connected or power cannot be continuously supplied to the catenary, the power is supplied to the traction motor through the internal combustion power supply module. When the two power supply modules need to be switched, the catenary power supply module and the internal combustion power supply module supply the power to the traction motor at thesame time during switching, and the replaced power supply module stops supplying the power when switching is finished. The switching control method for the hybrid power sources of the railway engineering machinery can achieve the technical purpose that when the two power sources are switched, it is ensured that an operating mechanism can run continuously without impact.

Description

technical field [0001] The invention relates to the technical field of railway engineering machinery, in particular to a hybrid power source switching control method applied to railway engineering machinery. Background technique [0002] At present, my country's railway construction machinery is basically powered by internal combustion engines, and the transmission mode is hydraulic transmission. Long-term practice has proved that the internal combustion hydraulic (hydraulic) transmission mode is stable and reliable, and can meet the traction requirements of railway construction machinery. However, with the increasingly stringent environmental protection standards, the improvement of energy saving and emission reduction requirements, the requirements of high power and high speed and the development of clean power sources, this method shows complex maintenance, serious environmental pollution and noise pollution, low efficiency and limited driving ability. and other limitatio...
