我是甲板出身,现在遇到继电器损坏,船吊不能正常工作,船长说是由于工人误操作,想请教各位大虾这种情况可能发生吗?继电器在船吊中起到什么作用?望各位不吝指教。谢谢继电器修好以后,船长又发现了新的损坏,其描述如下:
Please be informed that we had resolved the Crane no.3 Delta contactor issue on 4th June at 09:30 hrs when our good VM hand carried the spare Delta contactor from Singapore to the vessel.
This Crane no.3 was reported to you as operational and to the stevedores basis 04th June 09:30 hrs.
Afterwards the stevedores knocked off for their holidays on 5th and 6th June.
This morning upon testing the crane no.3 with grabs we noted that cable drum was not operational.
Basis further investigation we found the following :
Power supply rectifier for the cable drum brake coil was found to be damaged as the same has no output voltage 198V DC. Spare not available on board. We are currently checking for this in the local market.
As a result of above, the Crane no.3 cannot be used. My owner doing utmost to get the spare asap and will keep you posted.
电源整流器损坏应该又属于什么原因呢?
