Description
Technical field
The utility model relates to the switch cubicle technical field, particularly relates to a kind of heat radiation, preventing arc dividing plate that is used for pressing 3.6～40.5kV switch cubicle.
Background technology
Because the promulgation of switch cubicle industry technology standard GB3906-2006 version has proposed new requirement to the switch cubicle industry technology,, just change into and must do item by original option as the test of switch cubicle inside arcing.Cause that thus switch cubicle is more and more higher to the requirement that personal safety ensures.Though Medium Voltage Switchgear dividing plate originally has heat radiation, preventing arc effect, its real effect is not clearly, and original switch cubicle dividing plate process component is loaded down with trivial details, it is very high to require, thereby influences assembling speed.
The utility model content
Technical problem to be solved in the utility model is at existing Medium Voltage Switchgear dividing plate ventilation and heat, the preventing arc effect is not obvious and provide a kind of and be used for that Medium Voltage Switchgear effectively dispels the heat, the preventing arc dividing plate, this heat radiation, preventing arc dividing plate assembly technology are simplified, simple in structure, easy to assembly, but reliability height, not only result of ventilating heat dissipation is improved, and the preventing arc performance is increased.
Technical problem to be solved in the utility model can be achieved through the following technical solutions:
A kind of heat radiation, preventing arc dividing plate that is used for Medium Voltage Switchgear comprises the dividing plate body, is provided with the air channel in the described dividing plate body, and the rear portion of dividing plate body is provided with the stainless steel web plate, offers air inlet on the described stainless steel web plate; The preceding bottom of described dividing plate body is acclivitous inclined-plane, is provided with air outlet at the front upper part of dividing plate body; At least one arc quenching plate all is installed on the upper and lower wall in the air channel of described dividing plate body at interval, described arc quenching plate by after turn forward.
The twice arc quenching plate all is installed on the upper and lower wall in described air channel at interval, wherein arc quenching plate on the arc quenching plate and second is being installed at interval on the upper wall in air channel on first, arc quenching plate is positioned at arc quenching plate the place ahead on second on first, at interval first time arc quenching plate and second time arc quenching plate are installed on the lower wall in air channel, first time arc quenching plate is positioned at arc quenching plate the place ahead second time.
Arc quenching plate and first time arc quenching plate position of staggering on described first, arc quenching plate and second time arc quenching plate position of staggering on second.
Owing to adopted design as above, heat radiation, the preventing arc dividing plate that is used for Medium Voltage Switchgear described in the utility model adopts inclined design to make air intake unobstructed logical by the preceding bottom of dividing plate, and air quantity is big; And when internal arc produced, the arc quenching plate that electric arc is directed to absorbed arc energy effectively, electric arc can't be passed through smoothly, thereby guarantee personal safety.Dividing plate of the present utility model ventilates smooth and easy, reduces the temperature rise in the switch cubicle, reduces the copper bus-bar cross section, thereby reduces the manufacturing cost of switch cubicle.

Fig. 2 be among Fig. 1 A-A to structural representation.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1 and Figure 2, the utility model comprises dividing plate body 100, this dividing plate body 100 is made up of a upper plate 110 and a lower shoe 120 and stainless steel web plate 130, stainless steel web plate 130 is positioned at the rear portion of whole dividing plate body 100, it is provided with air inlet 131, and air inlet 131 adopts the IP4X degree of protection to be provided with.
Form an air channel 140 between upper plate 110 and the lower shoe 120, the air outlet 141 in air channel 140 is arranged on the front portion of upper plate 110, the front portion of lower shoe 120 become forward and make progress skewed, make ventilation smooth more.
140 the upper wall in the air channel just at interval is equipped with arc quenching plate 151,152 on the inner face of upper plate 110, and last arc quenching plate 151 is positioned at the place ahead of arc quenching plate 152, last arc quenching plate 151,152 by after turn forward.
140 the lower wall in the air channel just is equipped with down at interval arc quenching plate 151a, 152a on the inner face of lower shoe 120, following arc quenching plate 151a is positioned at the place ahead of time arc quenching plate 152a, following arc quenching plate 151a, 152a by after turn forward.Last arc quenching plate 151 and the following arc quenching plate 151a position of staggering, last arc quenching plate 152 and the following arc quenching plate 152a position of staggering.Arc quenching plate is installed, and mainly is the electric arc that produces when being used for extinguishing short circuit.
After outside wind is come in by the air inlet on the stainless steel web plate 130 131,, guarantee the unimpeded of air channel, form convection current, thereby reach radiating effect through last arc quenching plate 151,152 and following arc quenching plate 151a, the 152a of guiding design.
When electric arc produces, the gas pressure that last arc quenching plate 151,152 and following arc quenching plate 151a, 152a are produced by short circuit is to pusher, last arc quenching plate 151,152 becomes vertical with following arc quenching plate 151a, 152a by original turning forward, arc quenching plate 151 and following arc quenching plate 151a are misplaced up and down, and last arc quenching plate 152 misplaces up and down with following arc quenching plate 152a.When electric arc 160 moves to arc quenching plate 151 and following arc quenching plate 151a, most of electric arc is absorbed by last arc quenching plate 151 and following arc quenching plate 151a, even if there is a small amount of electric arc to cross, move so when transporting to arc quenching plate 152 and following arc quenching plate 152a, absorbed fully by last arc quenching plate 152 and following arc quenching plate 152a.Simultaneously, air-flow is outside then the interstitial row between the gap between last arc quenching plate 151 and following arc quenching plate 151a and last arc quenching plate 152 and the following arc quenching plate 152a offers for sale, thereby guaranteed personal safety.
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
