Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
See Fig. 1, Fig. 2, Fig. 3, passive self-excited constant voltage no-brush synchronous generator of the present utility model, comprise main generator and the exciter of coaxial setting, main generator adopts rotary pole formula generator, and exciter adopts revolving-armature type self-exciter; Main generator armature 1, main generator rotor 2 is provided with in described main generator, described main generator shell is provided with control cabinet 6 and automatic voltage regulator AVR7, described main generator armature 1 is embedded with main winding, and the auxiliary winding for powering to automatic voltage regulator AVR7; Be provided with armature of exciter 4 and exciter stator 3 in described exciter, described armature of exciter 4 is provided with rotary rectifier module 5; The input of rotary rectifier module 5 is connected with armature of exciter 4, and output is connected with the excitation winding of main generator rotor 2, and in described control cabinet 6, voltage transformer, current transformer are connected with main generator armature winding respectively.Main generator side is provided with support 8, and described exciter is arranged on support 8, and described exciter and main generator share same rotating shaft.
Rotary rectifier module is arranged on armature of exciter, and the input and output of rotary rectifier module are connected in armature of exciter and main generator rotor excitation winding; Measuring voltage instrument transformer in control cabinet and measurement current transform er are connected on main generator armature winding respectively, and output signal is supplied to AVR; When generator operation, exciter relies on the remanent magnetism on its stator to set up magnetic field, and when armature of exciter rotates, threephase armature induces three-phase alternating current electromotive force, through the rotary rectifier module of device on coaxial, after rectification, supply main generator rotor direct current exciting current.This main field when rotated, makes main generator unit stator winding induce three-phase alternating current electromotive force.Along with the rising of generator speed, generator voltage raises gradually.When rotating speed is close to rated speed, automatic voltage regulator AVR provide exciting current to AC exciter, time main generator voltage rise rapidly, and be stabilized in rated value.Generator is in normal course of operation, if because of certain reason (such as load variations, rotation speed change, each winding temperature change etc.) generator voltage have raise or reduce trend time, automatic voltage regulator AVR can be small according to this voltage deviation, reduce rapidly or increase exciting current, the voltage maintaining generator is similar to constant.
Owing to utilizing exciter stator remanent magnetism unshakable in one's determination, the voltage constant problem that solution generator excitation problem and load variations, rotation speed change etc. cause, ensure that generator is encouraged oneself completely, save external dc power or pilot exciter.Generator is from tape controller and automatic voltage regulator AVR, and AVR is directly powered by generator auxiliary winding, thus realizes encouraging oneself completely, is applicable to power autonomous special equipment of powering with field independent current source.
