Abstract

PURPOSE: To prevent improper urgent stop of a Diesel engine during emergency operation and stop it emergently once an abnormal operation is exactly detected during a test.
CONSTITUTION: An open contact 1, unexcited auxiliary-relay coil 2, open contacts 2al to 2a3, and closed contact 2b are provided when a unclear power plant urgently requires the operation of an emergency Diesel engine, Under the state the two contacts 4-1, 4-2 detecting the first abnormal operation are connected in seires. Even if the contact 4-1 or 4-2 is closed due to either malfunction of them, an emergency stop element 3 will not act. Once an abnormal accident may occur actually and the both contacts 4-1, 4-2 will work, the emergency stop element 3 works to stop said engine urgently.
