Description
Technical field
The utility model relates to electrical generator fields, refers more particularly to a kind of nine phase low-voltage direct brushless generators.
Background technology
Along with mobile communication subscriber is more and more, the amount of newly-built mobile base station and reconstruction mobile base station is increasing, generating set is as the important component part of the continous-stable work of mobile base station, demand is increasing, simultaneously, the signal that brings when how to reduce generating set work disturbs and energy-saving and emission-reduction, has also become problem in the urgent need to address.Existing standard threephase alternator is a universal product, when being applied to the mobile communication base station, mainly is the normal operation that guarantees the base station as stand-by power supply; Be the charge in batteries in the base station during its groundwork, when mains supply interrupts, also will bear the work into all base station electricity consumption facility powers; Based on this working condition, original standard threephase alternator can produce excessive voltage and current ripple at work, the signal transmission that this to a certain extent can the interference base station communication equipment.In addition, during charge in batteries fill soon with the floating charge pattern under needed electric weight be different, and the output of original standard threephase alternator is constant, can produce like this fuel oil waste, discharging increases.
Summary of the invention
The purpose of this utility model be to overcome above-mentioned weak point of the prior art and provide a kind of simple in structure, the ripple that improved the mobile communication base station disturbs, practical nine novel phase low-voltage direct brushless generators.
The utility model is realized in the following way:
Nine phase low-voltage direct brushless generators, it is characterized in that: comprise automatic voltage regulator A, armature of exciter B, rotating rectifier C, nine phase low pressure main generator unit stator armature D, rectification module E, cooling heat dissipation module F, described automatic voltage regulator A responds to mutually by exciter field G and armature of exciter B; Described armature of exciter B is connected with rotating rectifier C; Described rotating rectifier C is connected with nine phase low pressure main generator unit stator armature D by the main generator rotor magnetic field H; Described nine phase low pressure main generator unit stator armature D are connected with rectification module E; Described cooling heat dissipation module F is connected with rectification module E; Described nine phase low pressure main generator unit stator armature D are connected with automatic voltage regulator A respectively with rectification module E; Be connected with direct current output module I on the described rectification module E.
The beneficial effects of the utility model are: reduce the interference of voltage and current ripple: the application's voltage ripple＜1%, current ripples＜1.4%; The ripple that has greatly improved the mobile communication base station disturbs.Generator can be operated in high rotating speed 1800-2000 rev/min and 900-1200 rev/min according to charged state, and fuel consume and discharging are low.
