Embodiment Construction

[0020] The generator of the present invention works like this: the generator is driven by the prime mover, and after the unit is started, the harmonic winding generates voltage by relying on the residual magnetism, which supplies power to the automatic voltage regulator, and the automatic voltage regulator then supplies the excitation winding of the AC exciter. The excitation current makes the armature of the AC exciter generate electricity. The alternating current is rectified by the rotating rectifier module and then sent to the excitation winding of the main engine to generate a magnetic field, so as to realize the establishment of voltage of the main generator. As the speed continues to rise to close to the rated value, the automatic voltage regulation The generator controls the voltage of the generator to rise gradually, and finally stabilizes the terminal voltage at the rated value.

[0021] During the normal operation of the generator, if for some reason, such as: load c...

Abstract

The thirty-two-pole harmonic excitation medium-frequency generator is a small-medium three-phase brushless synchronous generator, and the 400Hz intermediate frequency electric energy is sent out through a 1500r / min diesel engine. , Excitation mode for harmonic excitation. The third harmonic voltage induced by the harmonic auxiliary winding of the stator is supplied to the automatic voltage regulator, and the automatic voltage regulator is used to supply the required current to the host, thus ensuring the whole generator running. Third harmonic is characterized by no-load third-harmonic voltage is very small; full load when the third harmonic voltage output voltage. The invention has the advantages that the harmonic excitation is strong with the non-linear load. It is an object of the present invention to provide a thirty-two-pole harmonic excitation intermediate-frequency generator which employs a harmonic excitation method and has the capability of super-starting an induction motor and having a nonlinear load.

Description

technical field [0001] The invention relates to a generator, in particular to a 32-pole harmonic excitation intermediate frequency generator. Background technique [0002] Due to the diversification of market demand, the demand for medium frequency generators is also increasing. If the frequency requirements are met by increasing the speed, then it is necessary to have an ultra-high-speed diesel engine or to add a transmission between the generator and the diesel engine, and sometimes even need to be equipped with The frequency conversion device will inevitably complicate the generator set and increase the cost a lot. Ordinary 1500r / min diesel engine is widely used in industry due to its advantages of less wear, low failure rate, long maintenance cycle, long life, good operation stability, high reliability, convenient purchase and good economy. However, the present invention can only be matched with a 1500r / min diesel engine to generate 400Hz intermediate frequency electric...
