220KV circuit breaker on the nameplate to write the rated closing time of 50 ~ 80ms, power station frequency frequency 50HZ, if a cycle is 0.02s that is 20ms in the same period during the closing period how to maintain the leading angle to meet the requirements, and to introduce some of the more professional book
This is more difficult to solve the current problem is that the same period or also known as the synchronization, which is the generator port breaker equipment Why use foreign products because of it, Siemens, ABB and other giants in this side of the study earlier, hope this link The paper can give you some help
This question is really more professional, the circuit breaker on the nameplate on the closing time, generally refers to the closing instructions to the last phase of the main arc chamber contact just a period of time. As the three-phase closing moment there is a time difference, so there is an important indicator, is the synchronization of the switch. As for how you want to keep the lead angle to meet the requirements, this also need to further check the information.
