In the withdrawing switch apparatus, the circuit breaker cart front end is upper and lower respectively to be provided with one group for the moving contact of line.During switch cubicle work, circuit breaker cart pushes cabinet outside cabinet after, hard-wired fixed contact is pegged graft in moving contact and the cabinet, finishes the connection of major loop; During overhaul of line breaker, circuit breaker cart is pulled out in cabinet.Be to guarantee safety in utilization, withdrawing switch apparatus will arrange valve mechanism usually, and its effect is: valve should be closed when circuit breaker cart is pulled out in the cabinet, and fixed contact is blocked, and prevents that mistake is bumped charged fixed contact in the maintenance process; When circuit breaker cart pushed cabinet, valve should be opened automatically, and moving contact can be passed through smoothly, cooperated with fixed contact.There are the defectives such as complex structure, installment and debugging is difficult, Reliability of Microprocessor is poor mostly in the valve mechanism of existing withdrawing switch apparatus, is difficult to guarantee the device security reliability service.
Summary of the invention
Technical problem to be solved in the utility model is, a kind of valve mechanism of simple in structure, installment and debugging convenient, Reliability of Microprocessor is high withdrawing switch apparatus is provided.
The valve mechanism of withdrawing switch apparatus of the present utility model includes a upper valve and a lower valve, the vertical guide post of upper and lower valve both sides and cabinet both sides is connected and can moves up and down along guide post, realizes that involutory the closing with separating of upper and lower valve opened; The both sides, rear of upper and lower valve respectively are provided with a pair of top link and a pair of lower swing arm; Described lower swing arm middle part is hinged with lower link for being hinged on the lower fixed pivot on the cabinet between the middle part of lower valve and the front end of lower swing arm; The rear end of top link is the upper fixed pivot that is hinged on the cabinet, is hinged with connecting rod between the front end of top link and the middle part of upper valve; Be hinged with back link between the rear end of lower swing arm and the middle part of top link, upper and lower swing arm can be swung synchronously; Be provided with the driving pin joint between the front end of described lower swing arm and the lower fixed pivot, this drives pin joint and the drive link upper end is hinged, and the drive link lower end is hinged on the front portion of a drive plate, and the rear portion of drive plate is hinged on the cabinet; Be fixedly connected with a guide plate on the drive plate, this guide plate is low heeling condition behind the front height under free state, the circuit breaker cart both sides are provided with the spacer pin that cooperates with spigot surface, circuit breaker cart pushes spacer pin described in the cabinet process and can move to the forward position guide plate from rear, and guide plate is depressed into level.
Be connected with the extension spring that upper and lower swing arm is drawn between described top link and the lower swing arm.
Be arranged with a plurality of hinge holes from top to bottom on the described upper and lower valve, described upper and lower connecting rod is selectively hinged from different hinge holes, with the stroke of governor valve.
The utility model is simple in structure, installment and debugging is convenient, can directly be driven by the action that pushes of circuit breaker cart its flexible movements, reliable.
