Description
Technical field
The utility model relates to a kind of electrical machine element, specifically is a kind of rectifier bridge group that is used for generator.
Background technology
The rectifier bridge group that is used for generator is to be galvanic motor accessory with AC rectification.Its structure generally comprises rectifier cell plate and rectifying tube.Three blocks of rectifier cell plates of rectifier bridge group operated by rotary motion that are used for generator of prior art, described every block of rectifier cell plate is provided with rectifying tube, the three-phase alternating current input wires is electrically connected with rectifying tube on three blocks of rectifier cell plates respectively, is exported by the direct current output contact on the rectifier cell plate through the electric current after the rectifying tube rectification.The rectifier bridge group that is used for generator of this structure comes with some shortcomings in actual applications, because this wiring point that is used for the rectifier bridge group of generator is welding, this just requires the quality height that welds, otherwise can cause conducting electricity loose contact.The rectifier bridge group that is used for generator of this structure is easy to cause solder joint to come off because the wiring solder joint is more, influences rectification effect.
In addition, the above-described rectifier bridge group that is used for generator, adopt three blocks of independently rectifier cell plates, the rectifier bridge group assembling of generator is comparatively bothered, moreover its surface radiating area is little, can only be fit to the rectification of general less electric current, but for some big electric currents in rectification, can make heat radiation insufficient because the area of dissipation of rectifier cell plate is little, thereby damage the rectifier cell plate.
Summary of the invention
The technical problems to be solved in the utility model is, overcomes above existing technological deficiency, provides a kind of rectification effect good, and the rectifier bridge group that is used for generator easy to assembly.
Technical solution of the present utility model is, a kind of rectifier bridge group that is used for generator with following structure is provided: it comprises rectifier cell plate, rectifying tube, described rectifier cell plate is provided with the groove of installing for rectifying tube, described rectifier cell plate is provided with the direct current output contact, described rectifier cell plate is two, a described rectifier cell plate I is provided with three rectifying tube I, and another piece rectifier cell plate II is provided with three rectifying tube II; The negative electrode of described three rectifying tube I is electrically connected with rectifier cell plate I, and the anode of three rectifying tube II is electrically connected with rectifier cell plate II; Each cross streams electricity input wires in the described three-phase alternating current input wires all is electrically connected with the anode node of a rectifying tube I and the negative electrode node of a rectifying tube II is electrically connected.
After adopting above structure, the rectifier bridge group that the utility model is used for generator compared with prior art, have the following advantages: this rectifier bridge group that is used for generator adopts two blocks of rectifier cell plates, the solder joint of rectification wiring is reduced, alleviated the weld strength of the rectifier bridge group that is used for generator, rectification effect is good.Moreover two blocks of rectifier cell plates make assembling convenient.
As a kind of improvement, described each rectifying tube I and each rectifying tube II at least one shunting rectifying tube all in parallel.Described shunting rectifying tube can be alleviated rectification pressure when carrying out the rectification of big electric current, make this rectifier bridge group that is used for generator not only be fit to the rectification of less electric current, and be fit to the rectification of big electric current, makes rectification wider.
