Description
Technical Field
The application relates to the technical field of over-current protection, in particular to a generator protection device with over-voltage protection.
Background
The overvoltage protection is used for protecting the overvoltage of the stator caused by various running conditions of the generator, the no-load state and the load state of the generator are not distinguished, and the generator is disconnected firstly and then the magnetic switch is tripped when in action, and the generator discharges and demagnetizes. In the prior art, the overvoltage protection fixed value of the generator is 1.3 times of 0.5s (namely, 1.3 times of the rated voltage of the generator). In practice, however, during false positive excitation in the no-load condition, the continuous increase in generator voltage will cause the continuous increase in rotor current, i.e. rotor magnetic energy. The generator rotor voltage suddenly bears more than 2 times of rated exciting voltage, and the rotor current and the stator voltage rise rapidly. Because of the saturation factor of the no-load characteristic of the generator, when the stator voltage rises to 1.3 times, the rotor current reaches about 2 times of rated exciting current; the overvoltage protection of the generator is delayed for 0.5 seconds by 1.3 times, and the delay of the magnetic extinction switch and the tripping circuit is delayed for 0.1 seconds, so that the stator voltage is approximately 1.4 times, and the rotor current and the rotor magnetic energy are approximately 3 times. The magnetic switch is in the danger of failure in demagnetization and burning down under the condition of large current and large energy.
Namely, the overvoltage protection method in the prior art has the defects of insufficient treatment of the overvoltage of the stator generated by self-shunt no-load false-strong excitation, increased burden of a demagnetizing device, great potential safety hazard and the like.
