Problems solved by technology

This type of transformer has high noise and low efficiency, and the fan needs to consume driving power, which requires more maintenance work. The train needs to be equipped with special protection devices and control logic to monitor whether the cooling fan is working normally when the train is running, which is inconvenient for operation and maintenance. and higher cost
However, some traction transformers cooled by coolers have the problem of inconvenient installation and maintenance.

Abstract

The invention relates to the field of rail transit and electricity and discloses a traction transformer assembly. The traction transformer assembly comprises a support assembly, a traction transformer body, a cooler and a pipeline assembly. The support assembly comprises a pair of longitudinal beams and a pair of cross beams vertically connected between the pair of longitudinal beams, the traction transformer body is connected between the pair of cross beams in a hanging mode, the cooler is connected to one side of the traction transformer body, and the pipeline assembly is communicated with the traction transformer body and the cooler. And the motor is used for driving cooling oil to circulate in the traction transformer body and the cooler. The traction transformer assembly is convenient to install and maintain, safe and reliable in operation and simple in arrangement.

Description

technical field [0001] The present application relates to the fields of rail transportation and electrics, and in particular, to a traction transformer assembly. Background technique [0002] Traction transformers for rail transit vehicles are installed on trains to convert the 25kV high-voltage electricity of the catenary into various low-voltage electricity required by the traction system and auxiliary systems. At the same time, it is necessary to suppress harmonic current and limit short-circuit current, so as to ensure the safe, stable and reliable operation of the train electric drive system. It is the power source of rail vehicles and the core and key component of the traction system. [0003] The existing rail transit vehicle traction transformer usually adopts the cooling method of forced ventilation by cooling fan. This kind of transformer has high noise and low efficiency, the fan needs to consume driving power, and there is a lot of maintenance work. The train ne...
