Abstract

The invention relates to a generator rotor RSO test simulator, a simulation system and a use method. The generator rotor RSO test simulator comprises a positive wiring terminal, a negative wiring terminal, a ground terminal, N sets of winding simulation circuits and a fault simulation circuit, wherein the N is an integer greater than 1, the N sets of winding simulation circuits are connected in series, one end of the winding simulation circuits connected in series is connected with the positive wiring terminal, the other is connected with the negative wiring terminal, each winding simulation circuit is connected with the ground terminal, the fault simulation circuit is connected with the winding simulation circuits, and various faults of the generator rotor RSO test simulator are made by controlling the on and off of the fault simulation circuit. The generator rotor RSO test simulator is advantaged in that the different faults of an electronic rotor can be simulated without the need for a true electronic rotor, development of training skill competitions is convenient, and a lot of funds is saved.

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
