Abstract
The invention relates to a high-power power electronic capacitor for elastic connection among core sets and copper bars. The high-power power electronic capacitor comprises a cover plate assembly, an outer shell and the core sets. The core sets are fixed in the outer shell, leading-out copper strips are arranged on the two metal sprayed faces of each core set respectively, and bent leading-out electrodes are arranged at the upper ends of the leading-out copper strips and used for being electrically connected with leading-out terminals of the cover plate assembly through welding. Elastic conducting plates are arranged on the leading-out copper strips and extend to all capacitor core metal sprayed faces of the core sets, and the tail end of each elastic conducting plate is electrically connected with the corresponding capacitor core metal sprayed face through the welding. The core sets are connected with the leading-out copper strips in an elastic mode. The force, adhering to the elastic conducting plates, of welding points is strengthened. The situation that the leading-out copper strips have sufficient properties of current passing can be guaranteed, and in addition, the situation that the displacement of the core sets causes the welding points to be strained can be eliminated, so that the welding points are not prone to loosening and disengaging.
Description
Technical field
The present invention relates to a kind of high-power electric and electronic capacitor, specifically the high-power electric and electronic capacitor that is connected with copper bar elasticity of a kind of core group.
Background technology
At present, adopt the high-power electric and electronic capacitor of cylindrical capacitor fuse, one or more groups core group is set in the shell, and every core assembly group is arranged side by side by row or two column capacitance device fuses, and every column capacitance device fuse is formed by stacking up and down by a plurality of cylindrical capacitor fuses; Every core assembly group both sides metal spraying face is provided with draws copper strips, draws the copper strips both sides and is electrically connected by solder joint at metal spraying face place with each capacitor body of two column capacitance device fuses respectively.The capacitor core quantum count of this core group is more, draws on the copper strips solder joint densely distributed.Because larger by the electric current of drawing copper strips, considered its overcurrent performance, drawing copper strips, general to cross the face cross section larger, is example such as the power electronic capacitor that is used for using on the FACTS/HVDC alternating current-direct current power transmission and transforming equipment, draw the width of copper strips at 20～200mm, thickness is at 0.25～1.0mm.Therefore, when welding, draw copper strips and can cause distortion because of welding stress, and because core group volume is large, weight is heavier, and being subject in capacitor transportation, installation and use procedure vibrated the displacement that can cause inevitably the core group, and this displacement is very likely pulled and drawn the rigidity solder joint that is electrically connected between copper strips and the metal spraying face, cause draw copper strips solder joint particularly welding stress concentrate the solder joint at place loosening or come off, cause its overcurrent performance impaired.
Summary of the invention
The purpose of this invention is to provide the high-power electric and electronic capacitor that a kind of core group is connected with copper bar elasticity, can avoid solder joint loosening or come off because capacitor is vibrated.
The present invention is achieved in that and comprises cover plate assembly, shell, core group; The core group is fixing in the enclosure, and the core group is fixing in the enclosure, and every core assembly group is arranged side by side by row or two column capacitance device fuses, and every column capacitance device fuse is formed by stacking up and down by a plurality of cylindrical capacitor fuses; Be respectively equipped with on the metal spraying face of every core assembly group both sides and draw copper strips, drawing the copper strips upper end has bending formation to be used for welding the extraction electrode that is electrically connected with the cover plate assembly leading-out terminal; Draw copper strips and be provided with the elastic conducting strip of each the capacitor body metal spraying face that extends to the core group, each elastic conducting strip is terminal to be electrically connected by welding with respective electrical container fuse metal spraying face.
Because elastic conducting strip is to draw copper bar to extend out, and has elasticity.Therefore, the core group with draw copper strips and realize that by elastic conducting strip elasticity is connected.The width of drawing copper strips is constant, can guarantee enough overcurrent performances, and the impact of its displacement is eliminated in elastic conduction sector-meeting generation elastic deformation during the displacement of core group, can reduce pulling of butt welding point, so that solder joint is difficult for loose or dislocation.In addition, solder joint can cover elastic conducting strip end and both sides fully, and solder joint is with the terminal parcel of elastic conducting strip and be attached to metal spraying face surface, can also strengthen adhesive force.
Preferred version of the present invention is: each elastic conducting strip is provided with crooked fold.By crooked fold is set, can increase elastic conducting strip elasticity, can further protect solder joint.
The present invention draws the separately machine-shaping of each elastic conducting strip on the copper strips, is fixed on by welding or riveted joint and draws on the copper strips.
The width of each elastic conducting strip is not more than 10mm.The elastic conducting strip good springiness of this width, the butt welding point protection better.
As shown from the above technical solution, the core group with draw copper strips and realize that by elastic conducting strip elasticity is connected, solder joint is to the Adhesion enhancement of elastic conducting strip, both can guarantee to draw copper strips enough overcurrent performances had been arranged, can eliminate again the displacement of core group to the pulling of the butt welding point brought, so that solder joint is difficult for loose or dislocation.And simple in structure, be easy to assemble welding.
