当并联机组启动运行时

当并联机组启动运行时,首先达到稳定状态的油机将通过发电机组断路器连接到母线,此时应同时合上该油机对应的接地接触器,当6个接地接触器中任意一台闭合时,其余接触器应保持断开状态。
When the parallel units start up and run, the first oil engine to reach a stable state will be connected to the bus through the generator circuit breaker. At this time, the corresponding grounding contactor of the oil unit should be closed at the same time. When any one of the six grounding contactors is closed, the rest of the contactors should remain disconnected.
当该接触器故障无法合闸或已合闸的接地接触器故障时,此接触器应断开,同时闭合系统中任一台在线油机对应的真空接触器,保证某一时刻系统中只有1台发电机组的中性点经电阻器接地。
When the contactor fails to close or the ground contactor fails to close, the contactor should be disconnected. At the same time, the vacuum contactor corresponding to any on-line oil engine in the system should be closed to ensure that only one neutral point of the generator set in the system is grounded by the resistor at a certain time.
当该机组故障而需从母排上解列时聚氨酯软管 PVC软管 隔离墩模具 u型槽模具 护坡模具 pvc输送带 尼龙输送带 天津除甲醛 北京除甲醛 ,其对应的接触器断开,同时闭合系统中任一台在线油机对应的真空接触器,保证系统的接地是通过在线油机的接地来实现。
When the unit fails and needs to be disconnected from the bus, the corresponding contactor is disconnected, and the vacuum contactor corresponding to any on-line oil engine in the system is closed to ensure that the grounding of the system is realized through the grounding of the on-line oil machine
