Abstract
PURPOSE: To reduce safety valves into two for simplifying construction by connecting contacts of two safety valves equipped on a transformer tank to AND circuits and OR circuits and operating breaking circuits and alarming circuits with two systems of electric source.
CONSTITUTION: Contacts 10 and 11 of two safety valves 7 and 8 equipped on a transformer tank are respectively connected with the first and the second AND circuit 12 and 21 and also with the first and the second OR circuit 13 and 22. A breaking circuit 14 and an alarming circuit 15 to be operated by the first electric source 16 are operated by the AND circuit 12 and the OR circuit 13, while another breaking circuit 23 and alarming circuit 24 to be operated by the second electric source 25 are operated by the AND circuit 21 and the OR circuit 22. In this construction, when either of contacts 10 and 11 is closed, alarming circuits 15 and 24 are operated, and when both are closed, breaking circuits 14 and 23 are operated. Thus, the whole construction can be simplified by adopting two systems for electric source and reducing safety valves into two.
