Abstract

The invention relates to a generator rotor RSO test simulator, a simulation system and a use method. The generator rotor RSO test simulator includes a positive terminal, a negative terminal, a grounding terminal, N groups of winding simulation circuits, and a fault simulation circuit, wherein N is an integer greater than 1; N groups of winding simulation circuits are connected in series, and the One end of the winding simulation circuit is connected to the positive terminal, and the other end is connected to the negative terminal; each winding simulation circuit is connected to the ground terminal; the fault simulation circuit is connected to the winding simulation circuit, and the generator rotor RSO test simulator is manufactured by controlling the on-off of the fault simulation circuit various failures. By implementing the invention, different failures of the generator sub-rotor can be simulated without the need for a real generator sub-rotor, which facilitates training and competition, and saves a lot of money.

Description

technical field [0001] The invention relates to the field of generator rotor maintenance, and more specifically relates to a generator rotor RSO test simulator, a simulation system and a use method. Background technique [0002] Turn-to-turn short circuit of generator rotor winding will lead to local overheating of rotor winding, causing winding deformation or melting. Further development of faults will cause accidents such as burning out of retaining ring, magnetization of large shaft, or burning of journal and bearing bush. After the failure of the generator rotor, the repetitive pulse test method (Repetitive Surge Oscilloscope, RSO) can be used to detect and locate the fault point. [0003] However, the simulation and training of the above tests need to be carried out on real generator rotors. If there is no real generator rotor, it is impossible to conduct tests such as generator rotor AC impedance, and it is impossible to carry out relevant training courses and skill c...

[0003] However, the simulation and training of the above tests need to be carried out on real generator rotors

If there is no real generator rotor, it is impossible to conduct tests such as generator rotor AC impedance, and it is impossible to carry out relevant training courses and skill competitions

The price of a real generator rotor is often hundreds of millions of yuan. Staff who have not mastered the relevant practical skills directly conduct tests on the generator rotor, which may cause damage to the generator or instruments and the risk of misjudgment of test results.

Therefore, there is a lack of a simulator capable of performing generator rotor faults in the prior art
