Fig. 5 is the vertical view of the 5th embodiment of the utility model integrated high-pressure frequency converter.With shown in Figure 4 basic identical, difference is, input 4 and control system 3 simultaneously along with the perpendicular direction setting of the length direction of transformer 1, and make input 4 between control system 3 and transformer 1, two of control system 3 sides are emerging on the side plate of cabinet 5 like this, there are bigger space and zone that control button, handled easily are set.
Fig. 6 is the vertical view of the 6th embodiment of the utility model integrated high-pressure frequency converter.Itself and shown in Figure 5 basic identical, the difference be that input 4 and control system 3 are positioned at the left side of power cell 2.
In the implementation process of reality, according to the length relation of transformer and power cell, can select accordingly.For example, when the length of transformer during more than or equal to power cell, input and control system three's length sum, we can namely arrange power cell, input and control system word order along the transformer length direction.When the equal in length of the length sum of power cell and control system and transformer or myopia equate, we can with control system and input simultaneously along with the perpendicular direction setting of transformer length direction, make that like this floor space of square cabinet of formation is littler.
Fig. 7 is the vertical view of the 7th embodiment of the utility model integrated high-pressure frequency converter.When the length of the length specific power unit 2 of transformer 1 will be in short-term, transformer 1 and power cell 2 parallel aligned cloth postpones, both sides or a side at transformer 1 have vacant space, make control system 3 be positioned at the left side of transformer, input 4 is positioned at the right side of transformer, in other embodiment, input 4 can also be the left side that is positioned at transformer 1, and control system 3 is positioned at the right side of transformer 1.The space that utilizes two lateral ends of transformer that can try one's best like this, the feasible volume minimum that forms the cabinet 5 of an integral body.
Fig. 8 is the vertical view of the 8th embodiment of the utility model integrated high-pressure frequency converter.With shown in Figure 7 basic identical, difference is that control system 3 and input 4 all are positioned at the left side of transformer 5, and control system 3 and input 4 all arrange arrangement along the length direction of power cell 2.As shown in the figure, input 4 is folded between control system 3 and the transformer 1, makes the control button of control system 3 or control panel to reveal at two side plates of cabinet 5 like this, has bigger operation interface space, handled easily person work.Wherein, control system 3 and input 4 can be positioned at the left side of transformer 5 simultaneously, can also be positioned at the right side of transformer 5 simultaneously.
Fig. 9 is the vertical view of the 9th embodiment of the utility model integrated high-pressure frequency converter.With shown in Figure 8 basic identical, difference is that control system 3 and input 4 is simultaneously along with the perpendicular direction of the length direction (horizontal direction) of power cell 2 arrangement being set, and input 4 is folded between control system 3 and the power cell 2, makes control system 3 have more operating space equally.Wherein, control system 3 and input 4 can be arranged on the left side of transformer 1 simultaneously, can also be the right sides of the transformer 1 that arranges simultaneously.
In the implementation process of reality, according to the length relation of transformer and power cell, can select accordingly.For example, when the equal in length of the length sum of transformer, control system and input and power cell or myopia equate, can be with control system, transformer and input word order, namely simultaneously along the length direction arrangement of power cell.Under the length sum of transformer and control system and situation that equal in length or the myopia of power cell equate, can with control system and input along with the perpendicular direction setting of the length direction of power cell.Can make that so the integrated cabinet space availability ratio that forms is higher, volume is littler.
Figure 10 is the generalized section of an embodiment of the utility model integrated high-pressure frequency converter.As shown in figure 10, being arranged in the cabinet 5 of transformer 1 and power cell 2 parallel aligned, between transformer 1 and power cell 2, has supporting bracket 10 at the interface, has ventilation hole 6 on the supporting bracket 10, be three ventilation holes 6 shown in the figure, in other embodiment, the quantity of ventilation hole 6 and size are determined according to position and the quantity of the radiator of transformer 1 and power cell 2.The material of supporting bracket can be metal, also can be insulator.Side plate 11 at cabinet 5 has ventilating window 7, and its latus inframedium 11 is near power cell, control system or input.Have through hole 8 on the cabinet of cabinet 5 top 12, through hole 8 is used for installing cooling blower 9, and as the outlet of cooling air.The cabinet that cooling blower 9 is positioned on the transformer 1 pushes up on 12, and opposed up and down with transformer.Cooling blower can be centrifugal cooling blower, in the operating process of reality, open cooling blower 9, at this moment cooling air is earlier through ventilating window 7, in the ingoing power unit 2 power cell is dispelled the heat, under the guide effect of ventilation hole 6, enter into transformer 1 afterwards, transformer 1 is cooled off, spill out finally by crossing through hole 8.Wherein be the air channel of cooling air shown in the arrow among Figure 10.Because the caloric value of power cell in running is little, make cooling air flow through earlier behind the power cell, the temperature of cooling air can't rise too much, can also utilize again, therefore open the ventilation hole that plays guide effect in supporting bracket, make cooling air flow through again in the transformer, thereby transformer is dispelled the heat.So only need one group of cooling blower can solve the heat dissipation problem of integrated high-pressure frequency converter, thereby reduced the quantity of cooling blower, reduced cost.
Be to be understood that, though this specification is described according to each embodiment, but be not that each embodiment only comprises an independently technical scheme, this narrating mode of specification only is for clarity sake, those skilled in the art should make specification as a whole, technical scheme among each embodiment also can form other execution modes that it will be appreciated by those skilled in the art that through appropriate combination.
The above only is the schematic embodiment of the utility model, is not in order to limit scope of the present utility model.Any those skilled in the art, the equivalent variations of doing under the prerequisite that does not break away from design of the present utility model and principle, modification and combination all should belong to the scope that the utility model is protected.
