Abstract
The utility model relates to an inversion power unit chassis assembling structure of a cascade-type frequency converter. The structure is characterized by comprising a chassis as well as a capacitor, a function device, a radiator and a control part arranged in the chassis, wherein the radiator is arranged on one side of the chassis; the function device is arranged on the surface of the radiator; the capacitor and the control part are arranged on the other side of the chassis; and the control part and the radiator are arranged in a misplacing manner. The structure has the advantages that the chassis is compact in structure, the size is greatly reduced, and the mounting space is saved; an air flue is arranged on the right side of a rear plate of the chassis, a radiator is arranged in the air flue, the function device is arranged on the surface of the radiator, only the function device is radiated through the air flue, and the capacitor and the control part are not radiated through the air flue, so that the radiating effect is greatly improved, and the reliability of the products is improved; and the straight air flue is horizontally arranged and low in wind resistance, so that the radiating effect is further improved.
Description
Technical field
The utility model relates to a kind of tandem type frequency converter inverter power unit cabinet assembly structure.
Background technology
Frequency converter has purposes widely at industrial control field, high-voltage high-power frequency transformator, especially industry go up to heavy-duty motor control, the visual plant of speed governing.Formations such as Frequency Converter Control system, driving and protective circuit and power cell.Power cell is generally by rectification module, filter capacitor, inversion electric bridge etc.For the high-voltage high-power frequency transformator of operating voltage more than 3KV, receive device withstand voltage and Power Limitation, the version that generally adopts a plurality of power cell branches to be in series is called the tandem type frequency converter or is called many level of units in series formula frequency converter.The frequency converter of the form of this structure, the power cell that whenever is in series does not wait 3-12 (level), looks the height decision of output voltage, for three-phase output, nearly tens of transducer power unit quantity.
Generally speaking power cell is assemblied in the cabinet, some cabinet multiple row multilayers overlay and constitute the inversion rack in the rack.Because power cell is operated under the high-voltage large current state, the components and parts caloric value is big, and rectification module and inversion electric bridge all are equipped with radiator, and the inversion rack also adopts air blast cooling to dispel the heat.
The said inverter power of the utility model unit cabinet, device, radiator are abundant in the cabinet inside space utilization, connection and reasonable arrangement; Particularly electric capacitor and IGBT distance is little, and loop inductance is little, and electrical structure is good; And heat dissipation wind channel is unobstructed; Cabinet inside can fully be dispelled the heat, and windage is little, good heat dissipation effect.
Summary of the invention
The utility model technical problem to be solved provides a kind of frequency converter inverter power unit cabinet assembly structure, with the heat radiation row culture that improves power cell cabinet assembly structure, inversion cabinet and electrical structure etc.
In order to solve the problems of the technologies described above; The utility model provides a kind of tandem type frequency converter inverter power unit cabinet assembly structure, it is characterized in that, comprises cabinet and is located at electric capacity, function element, radiator and the control section in the cabinet; Described radiator is located at a side of cabinet; Function element is located at the surface of radiator, and described electric capacity and control section are located at the opposite side of cabinet, and control section and radiator dislocation are arranged.
Preferably, described cabinet comprises rectangular enclosure and the front panel and the rear board that are connected respectively with the front-end and back-end of rectangular enclosure.
More preferably, be respectively equipped with air outlet and air inlet on described front panel and the rear board, radiator is located in the air channel between air outlet and the air inlet.
The beneficial effect of the utility model is:
1, the cabinet inner structure is compact, and volume significantly dwindles, and practices thrift installing space.
2, cabinet rear board right side has an air channel; A radiator is housed in the air channel; Function element places spreader surface, and the benefit of arranging like this is only to dispel the heat to function element in the air channel, and capacitor and control section do not rely on this air duct radiation; Improve radiating effect so greatly, improved reliability of products.
3, the straight air channel of horizontal arrangement, windage is little, has further improved radiating effect.
Description of drawings
Fig. 1 is a frequency converter inverter power unit cabinet assembly structure rearview;
Fig. 2 is a frequency converter inverter power unit cabinet assembly structure interior view.
Embodiment
Specify the utility model below in conjunction with embodiment.
Embodiment
As shown in Figure 2, be frequency converter inverter power unit cabinet assembly structure interior view, described frequency converter inverter power unit cabinet assembly structure is made up of cabinet 5 and electric capacity 1, function element 2, radiator 3 and the control sections 4 be located in the cabinet 5.Described radiator 3 is located at a side of cabinet 5, and function element 2 is located at the surface of radiator 3, and described electric capacity 1 and control section 4 are located at the opposite side of cabinet 5, and control section 4 is arranged with radiator 3 dislocation, need be connected through copper bar between the part of connection.Distance between electric capacity and the function element 2 (IGBT) is little, and loop inductance is little.
Described cabinet 5 comprises rectangular enclosure and the front panel and the rear board that are connected respectively with the front-end and back-end of rectangular enclosure.As shown in Figure 1; For frequency converter inverter power unit cabinet assembly structure rearview, be respectively equipped with air outlet and air inlet on described front panel and the rear board, radiator 3 is located in the air channel between air outlet and the air inlet; The direction of arrow indication is the wind path direction; Air-flow is that radiator flows into from the cabinet rear portion, flows out through arriving case front panel behind the radiator, can make each parts on the radiator can both obtain the heat radiation of forced draft like this.
