Abstract

This invention relates to a brushless self-excited three-phase induced generator with a series compensation function composed of a stator, a cage rotor, a three phase stator winding, a three phase excitation winding, three excitation capacitors and three serial compensation condensers, in which, the three excitation condensers are connected in a star or a triangle shape to form three connectors, three leading out ends of the three excitation winding are connected with the connectors, the outputs of the three phase stator winding are connected with the three ends of the three compensation condensers and the other ends of which are connected with the three phase inputs.

Description

technical field [0001] The invention relates to a brushless self-excited three-phase induction generator. Background technique [0002] The traditional stand-alone self-excited induction generator consists of image 3 shown. Its working principle is as follows: under no-load conditions, the prime mover is used to drag the rotor 7 to rotate, so that the residual magnetic field of the squirrel-cage rotor 7 "cuts" the stator winding 9, and the residual electromotive force is induced in the stator winding 9, and is sent to Parallel capacitor 8 sends capacitive current, and after capacitive current flows through stator winding 9, it will generate magnetized stator magnetomotive force and magnetic field consistent with the direction of residual magnetism, so that the air gap magnetic field is strengthened, and the voltage of the generator is gradually established , which is the self-excitation process of the induction generator. However, after the generator is connected to the l...
