Abstract
The invention provides a power module and a converter. A hole array is formed in a water-cooling substrate of the power module and comprises through holes. Locating pins are arranged in part of the through holes or all the through holes. According to the technical scheme of the power module, the power modules can be clearly differentiated according to the positions of the hole arrays, the numbers of the through holes of the hole arrays, and the numbers of the locating pins arranged in the through holes of the hole arrays so that when the power modules are installed, the probability of mistaken installation can be greatly reduced and the installation accuracy of the power modules can be improved.
Description
Technical field
The present invention relates to electrical technology, relate in particular to a kind of power model and current transformer.
Background technology
Power model is after power electronic device and associated components thereof combine by certain function, the module that embedding forms.According to the difference of converter cabinet main circuit function, the function of power model is also different.But the power model that each function is different but may have similar outward appearance.Power model comprises water-cooling base plate, and is arranged on power electronic device and associated components thereof on water-cooling base plate.Water-cooling base plate has substrate and is arranged on the quick union on substrate.
Current transformer is the vitals on locomotive, and the different power model of several functions is installed on current transformer.In actual installation process, due to appearance similar, be easy to occur the phenomenon of mistake installation, the accuracy of installation is low.
Summary of the invention
The invention provides a kind of power model and current transformer, the accuracy of installing for improving power model.
The invention provides a kind of power model, wherein, offer porose array on the water-cooling base plate of described power model, described hole array comprises through hole, in part or all of described through hole, is provided with alignment pin.
Power model as above, preferably, each described hole array comprises three through holes, the center of circle of three described through holes is on same circle.
Power model as above, preferably, the quantity of described hole array is at least one group.
Power model as above, preferably, in the array of each described hole, through hole is measure-alike or different.
The present invention also provides a kind of current transformer, wherein, the arbitrary power model providing of the present invention is installed on described current transformer.
The power model that technique scheme provides, the alignment pin quantity arranging in the through hole of the included number of openings in the position of hole array, hole array and hole array from water-cooling base plate, just can clearly distinguish each power model, so when mounted, just can greatly reduce the probability that occurs that mistake is installed, improve the accuracy that power model is installed.
Brief description of the drawings
The water-cooling base plate structural representation of the first power model that Fig. 1 provides for the embodiment of the present invention one;
The structural representation of the second power model that Fig. 2 a provides for the embodiment of the present invention two;
The structural representation of the third power model that Fig. 2 b provides for the embodiment of the present invention two;
The structural representation of the 4th kind of power model that Fig. 2 c provides for the embodiment of the present invention two;
The structural representation of the 5th kind of power model that Fig. 2 d provides for the embodiment of the present invention two.
Embodiment
The water-cooling base plate structural representation of the power model that Fig. 1 provides for the embodiment of the present invention one.
The embodiment of the present invention one provides a kind of power model, wherein, on the water-cooling base plate 1 of described power model, offer porose array 2, in the part or all of through hole 3 of described hole array 2, be provided with alignment pin 4, herein, hole array 2 is specifically opened on the quick union of water-cooling base plate.
It should be noted that, the position that hole array is offered should not affect the normal performance of this power model, and herein, hole array is specifically opened in the water-cooling base plate quick union of power model near the position at middle part, this position should not affect the normal mounting of water-cooling base plate, does not affect the performance of water-cooling base plate yet.Due to the difference of each power model performance, hole array to offer position also different; If hole array to offer position identical, the setting position in each hole in the array of hole can also be changed, comprise that taking each hole array three through holes are as example, can become and be del being equilateral triangle, or by rectangular triangularity for being equilateral triangle.In addition, can also distinguish by the alignment pin inserting in the through hole of each hole array is set, such as inserting 1,2 or 3 alignment pins.
Visible, the power model that technique scheme provides, the alignment pin quantity arranging in the through hole of the included number of openings in the position of hole array, hole array and hole array from water-cooling base plate, just can clearly distinguish each power model, so when mounted, just can greatly reduce the probability that occurs that mistake is installed, improve the accuracy that power model is installed.
Further, the center of circle that each described hole array 2 comprises 3, three described through holes 3 of three through holes is on same circle.Included through hole 3 quantity of hole array 2 number depend on the common quantity of power model distinguished of needing, to be arranged on power model on current transformer as example, each hole array 2 comprises that three through holes 3 can meet user demand.
Preferably, in the array 2 of each described hole, through hole 3 is measure-alike, specifically referring to Fig. 1.
Further, the quantity of described hole array 2 is at least one group.Two groups of hole arrays 2 to be set on water-cooling base plate as example, but be not limited to this herein.
The power model that technique scheme provides, when installation, is difficult for makeing mistakes, and is convenient to safeguard change, and has reduced maintenance cost, and in addition, the hole array of offering on power model can too not affect power model and converter cabinet space yet.
Four kinds of different capacity modular structure schematic diagrames that Fig. 2 a-Fig. 2 d provides for the embodiment of the present invention two.The difference of the present embodiment and above-described embodiment one technical scheme is, the size difference of through hole 3 in the array 2 of each described hole in the present embodiment.Be so also for the ease of distinguishing each power model, while avoiding installing, occur mistake.
Particularly, power model shown in Fig. 2 a is traction four-quadrant module, power model shown in Fig. 2 b is traction four-quadrant copped wave power model structural representation, power model shown in Fig. 2 c is traction inverted power module structural representation, and the power model shown in Fig. 2 d is auxiliary inversion power model structural representation
The power model that technique scheme provides, logical arrays of vias can be distinguished each power model fast, thereby reduces the mistake installation of power model.
The embodiment of the present invention also provides a kind of current transformer, wherein, the power model that any embodiment of the present invention provides is installed on described current transformer.
The current transformer that technique scheme provides, the installation of its power model is more accurate, and installation effectiveness is improved.
Finally it should be noted that: above each embodiment, only in order to technical scheme of the present invention to be described, is not intended to limit; Although the present invention is had been described in detail with reference to aforementioned each embodiment, those of ordinary skill in the art is to be understood that: its technical scheme that still can record aforementioned each embodiment is modified, or some or all of technical characterictic is wherein equal to replacement; And these amendments or replacement do not make the essence of appropriate technical solution depart from the scope of various embodiments of the present invention technical scheme.
