(1)CT35 spring operating mechanism is available for operating 40.5kv SF6
vacuum circuit breaker and 72.5kv vacuum breaker. It can meet with the
requirements of GB1984 high-voltage AC breaker and the technical conditions of
the product, and all the indexes have reached and exceeded the relevant
standards of the high-voltage AC breaker in IEC56.
(2) This mechanism has a
electrical energy storage and manual energy storage two ways, closing operation
can be remote operated through closing-brake tripping device and rotating
handle.
(3)According to the different types of breaker, the mechanism has two
kinds of structure: CT35 without break-brake spring, according to the different
requirements of users, the institutions can be equipped with mechanism box and
secondary control circuit.
