Description
Technical field
The utility model belongs to the technical field of railroad coach supply unit more particularly to a kind of railroad coach DC600V
Power supply box.
Background technology
The running environment of railroad coach DC600V supply units (such as charger, inverter etc.) is more severe, runs
Cheng Keneng is influenced by unfavorable factors such as high temperature, high humidity, strenuous vibration and over-voltage and over-currents, with this so that supply unit is being run
Failure rate in the process is higher, and especially in the case where being subjected to higher overpressure or overcurrent and last longer, capacitance is possible to
It explodes.Since capacitance is in more closed environment, the explosion of capacitance can make the pressure meeting in supply unit
Suddenly increase, enormous impact then caused to babinet and door-plate, door-plate is caused to fly out babinet, so extremely may to personnel and
Car body etc. causes serious injury.
As depicted in figs. 1 and 2, existing railroad coach DC600V power supply boxs include babinet 1 ', door-plate 2 ', lock body 3 ', hang
Hang 4 ' and hook 5 ', wherein there is lock body 3 ' lock tongue 301 ', door-plate 2 ' to be removably fixed in case by the lock tongue 301 ' of lock body 3 '
On body 1 '；As shown in Figure 1, hanging 4 ' and hook 5 ', hanging 4 ' are fixedly mounted on babinet 1 ', hook 5 ' is fixedly mounted on door-plate
On 2 ', hanging 4 ' is inverted u-shaped, is equipped with the groove of perforation at the top of hanging 4 ', hook 5 ' is plate-like and equipped with perforative logical
The plate body in hole, the through-hole top of hook 5 ' is inlaid in the groove of hanging 4 '.
It is anti-that Chinese utility model patent CN204012297U discloses a kind of carriage air conditioner inverter power supply box door plate
De- device, the plate on the through-hole top of hook are in the folded plate for being additionally provided with an outside bending, to a certain extent can with this
It is fallen off when enough avoiding door-plate by strong impact power.
However, the technology that above-mentioned anti-drop device cannot fundamentally solve how to prevent capacitance explosion time door-plate from flying out is asked
Topic, concrete reason are as follows：
First, weak point analysis is carried out to railroad coach DC600V power supply boxs：Covering and door-plate are using the weather-proof of 2.0mm
Steel (trade mark Q310NQL2), door lock matrix use kirsite material, and lock tongue material is Q235, since lock tongue yield strength is less than
The yield strength of door-plate, and lock tongue forced area is far smaller than door-plate forced area, therefore when lock tongue is surrendered, door-plate
And lock base body is not yet surrendered, and is plastically deformed so as to cause lock tongue, and flexible deformation mainly occurs for door-plate, further relates to capacitance
The main reason for explosion Rear Door flies out is the plastic deformation of lock tongue and the flexible deformation of door-plate, wherein with the plastic deformation of lock tongue
Based on.
Then by taking charger as an example, the door-plate nearest away from capacitance is taken to do force analysis, door-plate buckle constrains 6 certainly with lock tongue
By spending, door-plate is fixed on the babinet of charger, and Static finite element analysis, analysis knot are carried out using ANSYS software end of door plate
Fruit as shown in figure 3, lock tongue be overlapped on the position on babinet be maximum weighted region, when air pressure reaches 105.55kPa in babinet,
The stress that lock tongue is subject to reaches yield point and deforms, identical as weak point analysis, and lock tongue deforms Rear Door and opens, due to door
Board button only constrains 4 degree of freedom of door-plate, and when the impact force being subject to is sufficiently large, door-plate buckle cannot fix door-plate and make
Door-plate flies out.
It can be seen from the above, the basic reason that explosion time causes door-plate to fly out, which occurs, for capacitance is that plasticity occurs for the lock tongue of lock body
Deformation, therefore the folded plate of the above-mentioned outside bending of power supply box door plate anti-drop device can only play the role of that door-plate is hindered to fly out, without
Flying out for door-plate, i.e. the power supply box door plate anti-drop device can be prevented not to have the angle being plastically deformed from the lock tongue of lock body to go out
The technical issues of hair, how solution prevents capacitance explosion time door-plate from flying out.
