The heat radiator is provided with the large power device which is connected with the electrolytic capacitors on the base via the bus-bars, removable side plates are arranged around the supporting frame, and the control circuit board is arranged at the inner side of the side plate. The utility model is installed and fixed by the shell, the heat radiator, the large power device and the control circuit board via a mutual independent mode, and a complete power unit can be assembled. Under the same power class and compared with similar products, the utility model has the advantages of good heat radiation, compact structure, small system size and convenient installation and maintenance.
Description
Technical field
The utility model relates to a kind of modular power unit that is applied in the high-power high voltage frequency converter.
Background technology
Power cell is the important component part in the high-voltage high-power frequency transformator, and it is main components and parts of realizing high-voltage frequency conversion and speed-adjusting, also is all multifactor critical pieces such as decision high-voltage high-power frequency transformator characteristic, volume.So, when power cell structure designs, not only to consider its ventilation and heat, also many factors such as its compact conformation, connection and reasonable arrangement be to consider, thereby performance index the best of big-power transducer, volume minimum made.
Traditional high-voltage high-power frequency transformator is often because components and parts, circuit board quantity are many and relation is complicated, power cell has only been accomplished components and parts, circuit board are integrated into one independently in the casing, but do not consider the problem of its inconvenience of installing, difficult in maintenance and systems bulky, simultaneously, productivity ratio is difficult to improve.
In the known designs, different according to the relative position of radiator and electrochemical capacitor in the past, power cell is divided into the power cell of horizontal type structure and the power cell of vertical structure.In horizontal type structure, arrange about radiator and electrochemical capacitor that operation is convenient relatively like this, but corresponding frequency convertor system volume is big, the space can not make full use of; In vertical structure, radiator and electrochemical capacitor are arranged up and down, have made full use of the space, and system bulk has reduced, but are installing strict order, mounting process complexity, operating difficulties.
Summary of the invention
In view of the foregoing, the purpose of this utility model provides a kind of compact conformation, installation/easy to maintenance, modified model modular power unit that volume is less.
For achieving the above object, the utility model is taked following design: a kind of modified model modular power unit, and it mainly is made up of housing, radiator, high power device and control circuit board; It is characterized in that: on the base of described housing, be fixed with electrochemical capacitor, adopt large-area busbar to be connected between electric capacity and the electric capacity; The top of support is fixed with described radiator around described housing; Described high power device is installed on described radiator; High power device is connected by busbar with electrochemical capacitor on being installed in described base; On the support removable side plate is installed around the described housing, described control circuit board is arranged in the installed inside of side plate.
Lower link on the slotted hole of the electrochemical capacitor busbar lap-joint employing segmentation on high power device on the described radiator and the described base.
Described housing, radiator, high power device and control circuit board are flexible connection.
The high power device that is installed on the described radiator adopts mode of installing independently of one another to be fixed on the radiator, connects by busbar to each other.
Because the utility model adopts above technical scheme, under same power grade, the utility model has the following advantages compared with similar products: compact conformation, and system bulk is little; Radiating effect is good; Installation, easy to maintenance, the efficient height.

Embodiment
As Fig. 1-shown in Figure 4, the utility model modular power unit mainly is made up of housing 1, radiator 2, high power device 3 and control circuit board 4.
On the base 11 of housing 1, be fixed with the electrochemical capacitor of arranging in certain sequence 12.For making inner neat, the compact conformation of power cell, adopt large-area busbar to be connected between electric capacity and the electric capacity.
As shown in Figure 3, the top of support 13 is fixed with radiator 2 around housing 1.High power device 3 is installed on the radiator 2.High power device 3 evenly arranges on radiator 2, like this can Homogeneouslly-radiating.In addition, 3 of high power devices also are to connect by busbar 31, and in the lap-joint 32 of power device and electric capacity busbar, in order to reduce the influence of erection stress, lower link on the slotted hole of employing segmentation is eliminated the influence of processing, assembling, transportation.All parts that are fixed on the radiator can install and fix separately, like this, after the radiator back-off is to the base support, only needs to connect several upper and lower circuit overlapped points and get final product.If need to overhaul, more the parts on the heat exchange radiator are also with very convenient, only need turn on up and down several interfaces and just can move radiator integral from support.
Around support 13, side plate is arranged, control circuit board 4 is arranged in the installed inside of a side side plate by screw.Debugging, during Maintenance and Repair, only need opening side plate and get final product, very convenient.
The base 11 of the utility model housing 1, housing 1, radiator 2, high power device 3 and control circuit board 4 all can independently be installed, be combined into complete power cell at last, and needn't be subjected to the wherein restriction of certain parts, so, assemble, keep in repair, debug very convenient.
The above only is preferred embodiment of the present utility model, and protection range of the present utility model is not limited thereto.Anyly all belong within the utility model protection range based on the equivalent transformation on the technical solutions of the utility model.
