The CT19 spring operated mechanism is specifically designed for operating the ZN28 high-voltage vacuum circuit breaker and other high-voltage circuit breakers with equivalent closing power in the 10KV handcart cabinet.
There are two energy storage methods for the closing spring of the mechanism: electric motor energy storage and manual energy storage. There are two types of closing operations: closing electromagnet and manual button operation. There are three types of opening operations: opening electromagnet, overcurrent trip electromagnet, and manual button operation.
The specifications of the institution and the main component parameters for its coordination are shown in the table:
