Description
Technical field
The utility model is mainly concerned with locomotive electric cad system apparatus field, refers in particular to a kind of water-impervious brake resistance.
Background technology
Brake resistance carries out electric braking energy absorbing device as rolling stock is widely used in locomotive and city rail vehicle electric traction system.In order to improve the power density of brake resistance, reduce the volume and weight of brake resistance, the brake resistance that power is larger is all provided with the resistive element of blower fan to inside and cools.During blower fan work, cooling-air sucks from rolling stock outside, and flows through the heat that the resistive element be arranged in air channel produced and take away, and enters afterwards in car body external environment condition.
Because brake resistance is higher for cooling requirements, therefore brake resistance duct outlet is generally positioned at top or the side of car body, is communicated with car body external environment condition, and this makes the water of external environment condition can be easy to enter air channel from air outlet.Owing to there is pressure differential inside and outside air channel, the water making to enter air channel except a part can directly under flow to except at the bottom of car, another part water because the relation of pressure differential installs gap by wind path wall gap or resistive element ooze out brake resistance to peripheral direction, can impact the electric equipment be arranged on around brake resistance.
In order to prevent the water of car body outside from entering air channel, existing brake resistance adds shutter at air outlet position.When blower fan works, shutter is opened by wind, and the air outlet of brake resistance is in communication with the outside, and the blast produced when utilizing blower fan to open stops the water of car body outside to enter in air channel.When blower fan stops, shutter is closed automatically, prevents the water of car body outside from entering in air channel.But still there is following technical problem:
(1) radiating effect is not good.When blower fan quits work, can automatically be closed by the shutter that wind is held, the remaining hot-air of brake resistance can not drain into car body outside because shutter stops, resistive element still remains on the higher state of temperature, is in the useful life that the higher state of temperature can affect resistive element for a long time.And shutter is movable part, after a certain time of operation owing to adhering to more pollutant, likely occur situation about can not be opened by wind, this is very disadvantageous for the brake resistance that cooling requirements is high, can not get the resistive element that cools can because temperature rise is too high scaling loss.
(2) still there is the hidden danger of infiltration.Shutter may occur becalming situation about can not automatically close only, the water of air outlet still can enter in brake resistance air channel, and ooze out brake resistance by wind path wall gap or resistive element installation gap to peripheral direction, the electric equipment be arranged on around brake resistance is impacted.
(3) shutter needs periodic maintenance to maintain, and maintenance workload is large, and maintenance cost is high.
