Abstract
The invention discloses a ventilation system of a light rail vehicle traction convertor. An air supply module is combined by an air inlet, a gauze filter and a centrifugal blower; a heat radiation module is combined by a radiator, a radiator cover and an air outlet; a ventilation system is combined by one air supply module and two heat radiation modules, the air supply module and the heat radiation modules are connected by an air deflector, and the two heat radiation modules are respectively arranged at two sides of the air supply module symmetrically. The installation and disassembly method of the invention is as follows: in the installation, the air supply module and the heat radiation module are firstly assembled outside the light rail vehicle and installed in the cabinet of the traction convertor; when in the disassembly, the air deflector is dismounted firstly and then the air supply module with the heat radiation module is dismounted. The invention designs the ventilation system into detachable three modules which are connected by the movable air deflector, thus leading to rather convenient installation and disassembly, very simple maintenance and the avoidance of rainwater absorption.
Description
Technical field
The present invention relates to a kind of light railway van traction current transformer ventilating system and installing/dismounting method thereof, particularly relate to a kind of traction current transformer ventilating system and installing/dismounting method thereof that in light rail car, the tramcar confined space, uses.
Background technology
The traction convertor installing space of light rail car is limited, and power demand is bigger, so the heat dissipation ventilation of light railway van traction current transformer has relatively high expectations, and in addition, because most of light railway van traction current transformer is installed in roof, the classification of waterproof of current transformer requires also very high.Traditional traction convertor radiator ventilating system has two kinds, a kind of is the water-filled radiator ventilating system, the advantage of water-filled radiator ventilating system is the radiating efficiency height, switching tube radiator volume is little, shortcoming is to safeguard extremely inconvenience, safeguards improper when serious even meeting permanent damage water-filled radiator ventilating system; A kind of is air-cooled aluminium radiator ventilating system, and the advantage of air-cooled aluminium radiator ventilating system is that cost is low, installs simply, and shortcoming is that the aluminium radiator volume is big, and radiating efficiency is low.In addition, because most of light railway van traction current transformer parts packing densities are bigger, cause the cooling system layout comparatively complicated, install, dismantle cumbersome, especially in airborne dust more season, light railway van traction current transformer needs regular dismounting to get rid of dust, owing to do not adopt modularized design, causes changing filter screen, gets rid of dust, more bothers very much during ventilating fan.
Traction convertor radiator ventilating system is very crucial in a traction convertor link, in case the heat radiation unfavorable condition occurs, will burn the traction convertor switching tube probably, causes whole traction convertor to quit work.
Summary of the invention
For solving existing the problems referred to above in the prior art, the present invention will design a kind of novel modular removable light railway van traction current transformer ventilating system.
For achieving the above object, technical scheme of the present invention is achieved in that a kind of light railway van traction current transformer ventilating system, comprise air inlet, filter screen, centrifugal fan, wind deflector, radiator, radiator cover, air outlet, described air inlet, filter screen, centrifugal fan is combined into the air feed module, described radiator, radiator cover, air outlet is combined into radiating module, be combined into a ventilating system by an air feed module and two radiating modules, connect the symmetrical respectively both sides that are installed in the air feed module of described two radiating modules between described air feed module and the radiating module by wind deflector.
Radiator of the present invention is a heat-pipe radiator.
Air inlet of the present invention is positioned at air feed module bottom central authorities.
Centrifugal fan of the present invention is the big centrifugal fan of power to volume ratio.
A kind of installing/dismounting method of light railway van traction current transformer ventilating system is achieved in that and assembles earlier air feed module and radiating module when installing outside the light rail car, then the air feed module is installed on traction convertor bottom of cabinet bulk central authorities, the air inlet of air feed module is aimed at the air inlet of bottom of cabinet bulk central authorities, two radiating module symmetries are installed on the both sides of air feed module, between air feed module and radiating module, wind deflector is installed again at last, remove wind deflector during dismounting earlier, and then dismounting air feed module and radiating module.
Air feed module of the present invention and radiating module are installed does not have sequencing, and dismounting does not have sequencing yet.
Compared with prior art, the present invention has following beneficial effect:
1, because the present invention becomes dismountable three big modules with Design of Ventilation System, independent fully each other, by connecting by movable wind deflector, make installing/dismounting very convenient, also make maintenance maintenance become very easy simultaneously.
2, because air inlet of the present invention is positioned at bottom of cabinet bulk central authorities, and air outlet is positioned at the cabinet both sides, both changed the direction of air intake, air-out, can fully suck cabinet bottom cold air again, simultaneously because air inlet away from the cabinet side, can avoid sucking rainwater.
3, because the present invention has changed the aluminium section bar radiator of conventional art into the heat-pipe radiator heat radiation, accelerate the thermal cycle of switching tube, strengthened the switching tube cooling effect.
4, because the present invention has adopted the big centrifugal fan of power to volume ratio, improve the power of blower fan to greatest extent, greatly improved the ventilation effect of traction convertor.
