The independent air-cooled structure of bus-bar room, by bus-bar room bent plate, bus-bar room sealing plate, middle upper spacer, head cover and the side plate structure of cabinet both sides
Into enclosure space, heat emission hole is no longer opened up on the bus-bar room bent plate, bus-bar room sealing plate, the head cover Up Highway UHW ceiling portion corresponds to
Position open up ventilation oblong aperture, as air inlet I, position on the upper side is equipped with suction ventilator on the outside of the middle upper spacer, on every
Suction ventilator correspondence position offers ventilation circular hole II on plate, and the wind outlet of the ventilation circular hole II is equipped with ventilating duct.
Further, the ventilating duct includes the wind shield one arranged on suction ventilator both sides, wind shield two and arranged on suction ventilator
The wind shield three of bottom, wind shield three are obliquely installed, one end of wind shield one, wind shield two and wind shield three be fixed on every
On plate, upper end is concordant with middle upper spacer, and connects with head cover, forms oblique space.
Further, the corresponding position of ventilating duct is equipped with air outlet III on the head cover.
Further, I area of air inlet is more than III area of air outlet.
Compared with prior art, the utility model advantage is：Busbar cell structure and its air passage are optimized, made
The ventilation and heat for obtaining bus-bar room forms an independent space compared with other compartments, and heat in space can be made timely and fast
Being drained by suction ventilator for speed, is fast and effectively radiated, is independent of each other with other compartments, is solved high current metal-enclosed type and is opened
It closes cabinet busbar room temperature and rises the problem of exceeded；It has the advantages of simple structure and easy realization.

Specific embodiment
Below in conjunction with the accompanying drawings and specific embodiment is further described the utility model.
Fig. 1 is the stereogram of metal-enclosed switchgear, in order to make it easy to understand, switchgear left plate 1 and head cover 5 are moved
Position, for structure as shown in Fig. 2, cable vault is located at lower part, bus-bar room is located at top, and left side is handcart room, bus-bar room and cable vault it
Between for bus-bar room bent plate 1 and bus-bar room bent plate 23, bus-bar room one side is bus-bar room sealing plate 2, is set between bus-bar room and handcart room
Middle upper spacer 7.
As shown in Figures 2 and 3, the independent air-cooled structure of the metal-enclosed switchgear bus-bar room of the utility model, by mother
Line room bent plate 1, bus-bar room bent plate 23, bus-bar room sealing plate 2, middle upper spacer 7, head cover 5 and the left plate 1 of cabinet both sides and the right side
Side plate 10 forms enclosure space, and bus-bar room copper bar 9 is the main pyrotoxin of bus-bar room, with continuing through for high current, especially
Busbar lap-joint and other junctions, can generate substantial amounts of heat, and busbar room temperature is caused to raise.And the mother of the utility model
Line room bent plate 1, bus-bar room bent plate 23 no longer open up heat emission hole on bus-bar room sealing plate 2, make it completely enclosed, female on head cover 5
The corresponding position in line ceiling portion opens up ventilation oblong aperture, and as air inlet I 51, middle 7 outside position on the upper side of upper spacer is equipped with suction
Wind turbine, suction ventilator correspondence position offers ventilation circular hole II 4 on middle upper spacer 7, and suction ventilator takes away heat in bus-bar room, hot at this time
Amount drains heat because to design independent ventilation air duct, i.e., is equipped with ventilation in the wind outlet of ventilation circular hole II 4 into handcart room
Road.
Ventilating duct includes wind shield 1, wind shield 2 63 and the keeping out the wind arranged on air draught motor spindle arranged on suction ventilator both sides
Plate 3 62, wind shield 3 62 are obliquely installed, one end of wind shield 1, wind shield 2 63 and wind shield 3 62 be fixed on every
On plate 7, upper end is concordant with middle upper spacer 7, and connects with head cover 5, forms oblique space.Wind shield 1,2 63 and of wind shield
Wind shield 3 62 belongs to the special designing sheet metal component for independent ventiduct, remaining is cabinet universal architecture sheet metal component.
The corresponding position of ventilating duct is equipped with air outlet III 52 on head cover 5, the design for being radiated and being divulged information according to switch cabinet structure
Principle, I 51 area of air inlet are more than III 52 area of air outlet, to ensure the needs of suction ventilator, avoid making causing negative pressure shape in cabinet
State, and be unfavorable for radiating.
When generating heat in bus-bar room, wind enters from air inlet I 51, is operated through suction ventilator, by wind from bus-bar room through logical
Wind circular hole II 4 is drained into ventilating duct space, while takes away the indoor heat of busbar, and then the air outlet III 52 through cabinet top flows
Go out, the oblique space of ventilating duct can guide the wind of bus-bar room out and heat into air port III 52 on cabinet top head cover 5, possess drainage
Effect.
In conclusion the utility model has the advantages of simple structure and easy realization；Busbar cell structure and its air passage are optimized and set
Meter so that the ventilation and heat of bus-bar room forms an independent space compared with other compartments, can make in space heat and
When and rapidly drained by suction ventilator, fast and effectively radiated, be independent of each other with other compartments, solve high current metal envelope
Closed switch cabinet busbar room temperature rises the problem of exceeded；The mistake caused by busbar technique is unqualified can be also made up to a certain extent
Heat problem.
Certainly, the above description is not intended to limit the present invention, and the utility model is also not limited to the example above, this
The those of ordinary skill of technical field, in the essential scope of the utility model, the variations, modifications, additions or substitutions made, all
The scope of protection of the utility model should be belonged to.
