Description
Technical field
The present invention relates to a kind of generator, more particularly to a kind of novel permanent magnetic excitation system generator.
Background technology
Traditional permanent magnet excitation generator operation principle is after generator startup, voltage to be provided by permanent magnetic motor, through turning
Exciting current is provided to exciter stator after sub- adjuster rectification, exciter rotor voltage gradually rises, the alternating voltage is through rotation
Main rotor magnetic field is sent into after turning rectifier rectification, main generator is set up voltage, when rotating speed is close to rated value, automatic voltage
Adjuster makes generator voltage rise rapidly, and stabilization is in rated value.
Generator in normal course of operation, if because of certain reason, for example：Load change, rotation speed change, each winding temperature
Change etc., when generator voltage has the trend being raised and lowered, automatic voltage regulator can detect voltage deviation.By certainly
Dynamic voltage regulator decreases or increases exciter stator current, changes exciter stator magnetic field, controls the exciter rotor voltage to be
Main rotor provides electric current, changes main rotor magnetic field and maintains the terminal voltage of generator approximately constant.In whole control process certainly
Dynamic voltage regulator changes rotor magnetic field by controlling excitation accessory system.But excitation accessory system magnetic field is easily subject to
Main winding magnetic field influences, and when generator voltage has the trend that is raised and lowered larger, maintains the terminal voltage of generator approximate
Constant to need the repeated multiple times regulation of automatic voltage regulator, the whole regulation process reaction time is more long.Influence user's use quality.
Traditional permanent magnet excitation generator excitation accessory system volume is larger, heavier-weight.When generator is designed, to ensure
Shaft strength, typically can be using shaft diameter or the more preferable material of performance be increased, so as to increased the manufacturing cost of generator.
Therefore need to find a kind of generator design and solve problem above so that permanent magnet excitation generator small volume, weight saving and into
This reduction, can improve Generator Stable, mapping again.
The content of the invention
It is an object of the invention to provide a kind of novel permanent magnetic excitation system generator, the generator has lightweight, body
The characteristics of accumulating small, stable state, mapping are good, it is adaptable to permanent magnet excitation generator.
The present invention is achieved in that a kind of novel permanent magnetic excitation system generator, by fore bearing inner cap, fore bearing, preceding
Bearing end cover, drive end bearing bracket, main frame stator, main rotor, casing, adjuster control flow, rear end cap, rotor adjuster, signal are passed
Defeated device, rear internal bearing cover, rear bearing end cover, magnetic stator, band wound rotor, rear bearing, protective cover composition；Its feature exists
In：Adjuster control flow is arranged on casing, and signal transmission device is arranged in rear bearing by bolt and rear internal bearing cover seam
Cover, rotor adjuster is arranged on main rotor by connection ring, and with main rotor winding and with wound rotor cable
Line is connected, and magnetic stator is arranged on rear bearing end cover by bolt and rear bearing end cover seam, and band wound rotor passes through spiral shell
Bolt and alignment pin are arranged on main rotor；Main rotor is fixed with drive end bearing bracket and rear end cap respectively by fore bearing and rear bearing
On main frame stator, protective cover is bolted on main frame stator, when motor of generator control system is overhauled, can be prevented
Shield pulls down convenient maintenance.Fore bearing inner cap is bolted on drive end bearing bracket with fore bearing enclosing cover.
Generator main will be by fore bearing inner cap, fore bearing, fore bearing enclosing cover, drive end bearing bracket, main frame stator, main rotor, electricity
It is machine control system, casing, rear end cap, rear internal bearing cover, rear bearing end cover, magnetic stator, band wound rotor, rear bearing, anti-
Shield part is constituted.Electric machine control system includes adjuster control flow, signal transmission device, rotor adjuster parts composition；Forever
Magnetomechanical includes magnetic stator and band wound rotor.
Operation principle of the invention is：Generator amature adjuster directly controls rotor voltage to provide electric current for main rotor,
Adjuster control flow can realize real-time detection generator unit stator voltage, electric current, temperature and display rotor voltage, electric current, temperature letter
The functions such as breath；Rotor adjuster has AVR, rotating rectifier and information transfer, reception effect and can realize that detection turns simultaneously
The functions such as sub- voltage, electric current, temperature information.There is signal transmission device information processing, transmission and reception to act on, and be adjuster control
Screen provides bridge with rotor adjuster information transfer.After generator starts, voltage is provided by by permanent magnetic motor, adjusted through rotor
Electric current is provided to main rotor after device rectification, changes main rotor magnetic field, main generator is set up voltage, in rotating speed close to specified
During value, electric machine control system makes generator voltage rise rapidly, and stabilization is in rated value.Generator in normal course of operation,
If because of certain reason, for example：Load change, rotation speed change, the change of each winding temperature etc., generator voltage is raised and lowered
Trend when, adjuster control flow can detect voltage deviation.Rotor adjuster is transmitted a signal to by signal transmission device（Letter
Number transmitter passes through wireless transmission information with rotor adjuster）, directly control rotor voltage to provide electric current for main rotor, change master
Machine rotor magnetic field maintains the terminal voltage of generator approximately constant.
The solution have the advantages that：Signal transmission device, rotor adjuster belong to electronic component, and volume is smaller.Rotor
Adjuster directly controls rotor voltage to provide electric current for main rotor, eliminates excitation accessory system（Including exciter rotor）,
So as to alleviate the weight of motor, the volume of motor is reduced.Make electric moter voltage control system more directly simple, make motor steady
State, mapping are more preferable.Rotor voltage, electric current reality and temperature can be increased in adjuster control flow and implement real-time monitoring, protected
Demonstrate,prove the normal operation of motor and for electrical fault inquires about provides convenient.
