Specific embodiment
Embodiments of the present invention are described further with reference to the accompanying drawing.
The specific embodiment of switchgear of the invention, as shown in Figures 1 to 4, switchgear include cabinet body 1, the top of cabinet body 1
It equipped with heat release hole, is flowed upwards out conducive to the hot-air of interior of the cabinet, riser 8 is equipped in the inner cavity of cabinet body 1, riser 8 is by switchgear
Inner cavity be separated into left and right two parts, busbar 7 is set to the top of right side inner cavity.Riser 8 is for installing the electric appliances such as contact box member
Part, while ventilation hole is equipped on riser 8, it is flowed convenient for the chamber atmosphere of two sides.On the position of the close lower part of left chamber
Equipped with partition 2, left chamber is divided into the breaker chamber 3 in top and the cable vault in lower part 6 by partition 2.
Partition 2 includes horizontally disposed level board 21 and bends downward to form bending edge 22 on one side close to outside, curved
One wind of flanging composition cabinet body side wall.The logical of the outlet 23 for constituting air intake passage is distributed in level board 21 on the side of inside
Louver-type ventilation mouth is distributed on bending edge 22 in stomata vertically, these louver-type ventilation mouths constitute the import of air intake passage
25, the side of bending edge 21 is equipped with the flange 24 towards inside, and flange 24 is located at the removing of bending edge 22 and level board 21 connects
On other three sides of the side connect, these flange 24 and level board 21 match the flange for being encircled into slot, while being in two sides
On be additionally provided with for connecting hole connected to the cabinet body, in this way, partition 2 is just able to use the structure of original cabinet body, avoid to cabinet body
Again improvement and design reduces manufacturing cost.
Deflector 5 includes the bottom plate 51 in the lower wall for constituting air intake passage, and two sides of bottom plate 51 are folded upward at
Form the side wall 54 of air intake passage.Bottom plate 51 tilts upwards along air inlet direction, makes becoming in what is booted up for air intake passage in this way
Gesture boots up convenient for air.Deflector 5 extends outward to form the Internal periphery shape with 2 slot of partition close to the one end in outside
The cartridge part 53 of adaptation, cartridge part 53 are less than the length of the slot of partition along the length of airintake direction, and deflector 5 is close to inside
Side is equipped with the tongue 52 to overhang forward.When assembly, first the cartridge part 53 of deflector 5 is inserted into the slot of partition 2, by
It is deeper in slot, enable cartridge part to move backward certain distance, tongue 52 is on the outside of the slot on cabinet body at this time, then
Deflector is moved inward, makes to complete the assembly of deflector 5 in the slot of the inserting of tongue 52 on the cabinet.Pass through inserting
Mode, which connects, eliminates the connecting components such as bolt, reduces manufacturing cost, and enhance the leakproofness of air intake passage, avoids air
Outflow.After assembly in place, the downside of the level board 21 of bending edge 54 and partition 2 cooperates, and surrounds with import 25 and outlet 23
Air intake passage, export 23 at this time towards at 4 position of contact of breaker, contact box, pole at this and dynamic and static
Contact is the biggish element of calorific value, exports towards at this, cross-ventilation effect can be made more obvious, is conducive to reduce in cabinet body
The temperature in portion.
The air intake passage being directly connected to breaker chamber is equipped in switch cabinet body of the invention, the import of air intake passage is set
On the side wall of cabinet body, outlet is located at partition towards at the contact of breaker, and in use process, outside air passes through air intake passage
It is directly entered in breaker chamber, avoids air and disperse in cabinet body inner cavity, the wind in air intake passage flows directly into breaker hair
At the biggish contact of heat, enhance the heat dissipation at this, since the import of air intake passage is located on side, is conducive to air and enters；Together
When air intake passage be in acclivitous trend, gather upwards convenient for air.In the switchgear use process, by external wind pressure
And internal hot pressing function, enter external cold wind in cabinet body from air intake passage, since air flow property is good, so that heat dissipation effect
Fruit is remarkably reinforced.
In other embodiments of the invention, the bottom plate of deflector can also be horizontally disposed with, or can also set bottom plate
It is set to the arc panel being upturned, is more conducive to reduce air drag in this way；Partition level board also and bending edge can be with fissions
It is arranged and passes through welding or is bolted；Partition and deflector can also be by being welded to connect, or can also be in deflector
Flange is set on the connection side of partition, by the way that bolt hole is arranged on flange, setting connection bolt will on flange
Partition is connected and fixed with deflector；Venthole on partition can also be distributed on whole partition；Can also not have in cabinet body
There is riser, partition is fixed in interior of the cabinet by the frame in cabinet body at this time.
Cabinet body in the embodiment of the embodiment of switch cabinet body of the invention, the switch cabinet body and above-mentioned switchgear
Structure it is identical, repeat no more.
