Embodiment

In order to make the utility model technical problem to be solved, technical scheme and beneficial effect clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.

Fig. 1 is extremely shown in Figure 5 to be the uninterrupted power supply 100 of the utility model one embodiment, and it comprises casing and the electric elements that are installed in the casing.

Particularly, casing comprises base plate 210, front side board 220, back side panel 230, left plate 240, right plate 250, top board 260, door-plate 270 and demarcation strip 280.Base plate 210, front side board 220, back side panel 230, left plate 240, right plate 250 and case shape structure of top board 260 common compositions.Door-plate 270 is articulated on the front side board 220 in order to open or to cut out front side board 220.Demarcation strip 280 is positioned at box house, and box house is divided into lower layer space 292 and last sheaf space 294.

Wherein, base plate 210 is provided with wire hole and ventilation hole.The ventilation hole that outside cold air can pass through base plate 210 gets into lower layer space 292.Wire hole can be used for wearing cable etc.In addition, on the base plate 210 some wheels 212 can be installed further, with the convenient uninterrupted power supply 100 that moves.

As shown in Figure 2, front side board 220 is provided with ventilation hole 222, circuit breaker 224 and binding post cover plate 226.In the present embodiment, ventilation hole 222, circuit breaker 224 and binding post cover plate 226 from up to down are arranged in order.Be provided with like this, the user need open door-plate 270, could operate circuit breaker 224, can avoid mistake to bump the possibility of tripping operation; In addition, through binding post cover plate 226 is set, can prevent that the user from touching by mistake.

As shown in Figure 1, door-plate 270 tops are provided with man-machine interface 272, convenient related data of checking uninterrupted power supply 100 at any time.At leftward position place, door-plate 270 middle part, front door lock 274 is installed, can be with door-plate 270 lockings.On door-plate 270 bottoms, be formed with some ventilation holes 276, ventilation hole 276 communicates with ventilation hole 222 on the front side board 220.

As shown in Figure 3, from up to down be provided with fan 232, ventilation hole 234 and fan 236 on the back side panel 230 successively.For ease of difference, fan 232 can be described as sheaf space fan 232; Fan 236 can be described as lower layer space fan 236.

Demarcation strip 280 can be roughly parallel to base plate 210.Distance between demarcation strip 280 and the base plate 210 can design according to the actual requirements.Fan 282 is installed on demarcation strip 280.For ease of difference, fan 282 can be described as demarcation strip fan 282.

Electric elements can comprise transformer 310, power device 330 and signal plate 350 etc.Like Fig. 4 and shown in Figure 5, transformer 310 is positioned at lower layer space 292, can be installed on the base plate 210; Like this, both be convenient to install, the center of gravity that can guarantee uninterrupted power supply 100 again is following.And transformer 310 closes on the ventilation hole on the base plate 210, helps the heat radiation of transformer 310.Power device 330 can be installed the left side at last sheaf space 294 concentratedly like IGBT, SCR, electric capacity etc.; Signal plate 350 can be installed the right side at last sheaf space 294 concentratedly like master board, interface signal plate, IGBT and SCR drive plate etc.; Setting can make weak signal not receive the power section electromagnetic interference like this; Guaranteed the stability of uninterrupted power supply 100, and debugging and easy to maintenance.

Uninterrupted power supply 100 in use, transformer 310 all can produce heat with power device 330 grades.Wherein, through driving lower layer space fan 236, can make outside cold air get into lower layer space 292 through the ventilation hole on the base plate 210, the transformer 310 and absorb the heat of transformer 310 of flowing through is discharged in the external environment condition through lower layer space fan 236 then.Because transformer 310 closes on the ventilation hole on the base plate 210, and transformer 310 is between ventilation hole on the base plate 210 and lower layer space fan 236, hinders lessly, can the heat of transformer 310 generations be dispersed in the external environment condition in time.Through driving demarcation strip fan 282, can make the bottom-up power device 330 and mobile that blows to of air-flow to both sides, can the heat that power device 330 produces in time be taken away, to reduce the temperature of power device 330.In addition, through driving sheaf space fan 232, can the hot-air of going up in the sheaf space 294 in time be discharged in the external environment condition, the space temperature of avoiding the accumulation of power device 330 surface temperatures to cause rises.In addition, but the ventilation hole 222 on ventilation hole on the door-plate 270 276 and the front side board 220 also the heat that produces of accelerating power device 330 flow to both sides, strengthened and cool exterior air between heat exchange action.

The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection range of the utility model.
