润色在断路器检修时必须确保不会影响对系统的连续供电。这就意味着需要在设计和选择断路器时注意其可靠性和实用性。其次在任何一进出线断路器故障或拒动以及母线故障时都不能切除一台以上机组和相应的线路。这要求电气主接线的设计要充分考虑各种故障情况并采取相应的措施来保证电源的可靠性和稳定性。此外在任何一台断路器检修和另一台断路器故障或拒动相重合、以及当母线分段或母线联络断路器故障或拒动时也不应该切除两台以上机

In order to ensure the reliability of the main connection of large units in ultra-high voltage power systems, it is necessary to pay attention to their reliability and practicality when designing and selecting circuit breakers during maintenance. Secondly, when there is a fault or refusal of one incoming or outgoing line circuit breaker or a bus fault, one or more units and corresponding lines cannot be cut off. This requires the design of electrical main connections to fully consider various fault situations and take corresponding measures to ensure the reliability and stability of the power supply. In addition, when one circuit breaker is being maintained and another circuit breaker fault or refusal occurs, or when the bus is segmented or the bus connecting circuit breaker is faulty or refuses to operate, two or more units and corresponding lines should not be cut off. This requires designers to carefully analyze various possible fault situations when formulating the electrical main connection scheme, in order to ensure the normal operation of the power system in such abnormal situations. In summary, in order to ensure the reliability of the main connection of large units in ultra-high voltage power systems, it is necessary to fully consider various possible fault situations in the design and operation process, and take necessary technical and management measures to ensure the safe and stable operation of the power system
