Description of drawings
Fig. 1 is the stereogram of an embodiment of the utility model;
Fig. 2 is the front view of an embodiment of the utility model.
Embodiment
Like Fig. 1, shown in Figure 2; The utility model one embodiment comprises a plurality of capacitance modules 10 and a plurality of power models 20; Said capacitance module 10 links to each other with electric capacity busbar 11, and said power model 20 links to each other with power busbar 21, and said electric capacity busbar 11 vertically is connected with power busbar 21 each other; Said capacitance module 10 is positioned at the top of electric capacity busbar 11, and said power model 20 is positioned at the bottom of electric capacity busbar 11.
Further, the junction of described electric capacity busbar 11 and power busbar 21 is provided with boss.Can reduce bolted area like this, cause connection unstable thereby avoid leaving joint gap because of contact-making surface is excessive.
Further, the output stage of described electric capacity busbar 11 is arranged on front end.The output stage of electric capacity busbar can be positioned at the cabinet front portion like this, opens the cabinet door when safeguarding and just can realize front maintenance, greatly reduces the difficulty of maintenance.
Further; Said a plurality of power model 20 is vertically placed, and is parallel, and said power model 20 comprises radiator 24, radiator fixed head 22 and switching tube module 27; Said switching tube module 27 is fixed on the radiator 24, and said radiator 24 is fixed on the radiator fixed head 22.The lower surface of said electric capacity busbar is set with some guide rails 23, and radiator 24 lower ends are provided with bracing frame 26, and radiator fixed head 22 is nested in the guide rail 23 and can slides along guide rail 23 and bracing frame 26.When safeguarding like this, can module be pulled out along guide rail 23 and bracing frame 26 and safeguard, very convenient.
Further, the junction of described electric capacity busbar 11 and power busbar 21 is provided with riveting nut.What can make things convenient for electric capacity busbar 11 and power busbar 21 like this is connected convenient disassembly.
Further, described power busbar 21 is stack bus bar with electric capacity busbar 11.
Further, the positive pole of said a plurality of capacitance modules 10 connects through just connecting soft busbar 12 side by side, and the negative pole of said a plurality of capacitance modules 10 connects through the soft busbar 13 of negative connection side by side.For more effective realization energy storage, filter action, often need make a complete capacitance pool.Along with the continuous increase of developed horse power, the quantity of electric capacity also can constantly increase, if make a big capacitance pool, and the busbar easy deformation, and requirement on machining accuracy is high, cost of manufacture is high, installs, safeguards also all very inconvenient.Be divided into a plurality of capacitance modules to capacitance pool, be together in parallel the positive and negative electrode of a plurality of capacitance modules through the soft busbar of positive and negative connection then, the requirement that can satisfy energy storage, filtering is convenient to again install, safeguard, and processing cost is low, and busbar is not yielding.
