Throwing resistant attaching patsuhua shape gas breaker

摘要

PURPOSE: To prevent the rupture of a contact part by the bending moment generated at the time of completing breaking operation, in a buffer type gas circuit breaker with input resistance, ensure the flow of a current at the time of carrying the current to an input resistance, and suppress the overvoltage at the time of input. ;CONSTITUTION: The second movable electrode 42 of an input resistance contact is formed into a hollowed cylinder and supported by a guide part 43 mounted on one end of an input resistance 27 in such a manner as to be able to slide. A spring locking part 42a is formed on the top end part of the second movable electrode 42 of the input resistance contact, and a spring 26 is mounted between the spring locking part 42a and a spring receiving part 44 mentioned below. On the other hand, the spring receiving part 44 is fixed to a current-carrying cylinder 15 through an insulating member 25. The spring receiving part 44 is formed in a ring, and the second movable electrode 42 of the input resistance contact is movably provided on its central part. A determined gap is provided between the inner circumference of the spring receiving part 44 and the outer circumference of the second movable electrode 42 of the input resistance contact.;COPYRIGHT: (C)1993,JPO&Japio
