The contact pressure in the circuit breaker spring-and-gates, the role of spring vacuum interrupters minimizes the interactive conductive par 4 in institutions, as well as insulation trolley along with the sub-gates moves downwards, completed.

In the circuit breaker contact pressure spring and under the minute floodgate spring function, the vacuum explosion chamber moves leads the telephone pole in four link motion gears as well as under the insulation tension bar impetus the downward movement, completes the minute floodgate movement.

Circuit breaker contacts under the action of pressure spring and opening spring, vacuum interrupter conductive rod in the four-bar linkage and insulation, along with moving down to complete the opening action.
