The invention discloses a dual-power subway electric-drive steel rail grinding car and a power switching method thereof. The dual-power subway electric-drive steel rail grinding car comprises a power car and an operation car which is connected with the power car. The power car is provided with a pantograph type current collector and an internal combustion engine generator set; the operation car is provided with a grinding car for grinding. The steel rail grinding car uses a contact net as a complete vehicle power source or uses the internal combustion engine generator set as the complete vehicle power source. In a subway electrified region, the steel rail grinding car obtains power from the contact net through the pantograph type current collector and then supplies the power to a traction electric-drive system, a grinding system and an auxiliary system after being rectified and inverted; or the power is generated by the internal combustion engine generator set in an un-electrified region, and is supplied to the traction electric-drive system, the grinding system and the auxiliary system after being rectified and inverted. The dual-power subway electric-drive steel rail grinding car disclosed by the invention not only can be electrified through the subway contact net, but also can adopt internal combustion power in the un-electrified region as a whole vehicle power source to perform travelling and grinding operation, so that all electric driving in the travelling and grinding processes of the subway steel rail grinding car is realized.
Description
technical field [0001] The invention relates to a railway engineering and maintenance vehicle, in particular to a subway electric transmission rail grinding vehicle with dual power sources applied in the field of railway engineering and equipment maintenance and a power switching method thereof. Background technique [0002] The subway line has a large number of tunnel sections. The existing subway rail grinding vehicles use internal combustion power as the power source of the whole vehicle. During the grinding operation of the subway tunnel, the exhaust gas of the internal combustion engine is difficult to discharge, and a large amount of toxic gas and dust will bring great harm to the health of the workers. big damage. At the same time, it leads to power reduction and affects the normal operation of other systems of the vehicle. The installed power of subway rail grinding vehicles is large, and the fuel consumption is huge, which makes it difficult to reduce the cost of g...
