[embodiment]
Provide execution mode of the present utility model below in conjunction with accompanying drawing.
Referring to accompanying drawing 1.A kind of high-tension switch cabinet anti-misoperation interlock, chain controlling organization 1 is made up of handle and connecting lever, chain controlling organization 1 passes through the upper end of its connecting lever and yoke plate 2 (because of the needs of manufacture craft, make cambered surface slightly,) hang the pin connection with metal, the lower end of yoke plate 2 (being the plane) is connected with the screw rod of nut with drive rod 3 upper ends, drive rod 3 is enclosed within the hole of drive rod support 4, can move up and down, push up mutually with an end face of lever 6 lower end of drive rod 3, the stage casing of drive rod 3 is set with the chain locking ring 54 of chain locking mechanism 5, chain lock bracket 53 is installed on drive rod support 4, chain stop pin 52 moves in the hole of chain lock bracket 53, an end of chain stop pin 52 and the connecting lever pin joint on the circuit breaker main shaft 50; The fulcrum of lever 6 is fixed under the circuit breaker noseplate with pivot pin 7 in the left side at lever middle part, the other end suit ejector pin 8 of lever 6, and the lower end pin joint of ejector pin 8 and push rod 9, push rod 9 is up and down in the hole of inner support 10; The upper end of push rod 9 and circuit breaker tripping device 15 maintain the apical grafting of intermittence, (enter the centre position) on the push rod 9 and be set with push pedal 12, on the inner support 10 of both sides, push pedal 12 top sensitive switch 13 is housed, the contact of sensitive switch 13 is being controlled combined floodgate circuit and switch knob locking.
When the beamhouse operation isolating switch, (possessed the operating condition of isolating switch this moment) in the time of chain controlling organization 1 should being allocated to " operating position " C, the connecting lever of chain controlling organization 1 clockwise rotates, make yoke plate 2, drive rod 3 presses down, force an end of lever 6 to sink, the ejector pin 8 of lever 6 other ends rises, with top in push rod 9 and the push pedal 12, push rod 9 is triped circuit breaker tripping device 15, and push pedal 12 disconnects sensitive switch 13, cuts off the circuit of blocking coil 16 and closing coil 17, after blocking coil 16 outages, lockweight is subjected to the promotion of switching-in spring 11, and combined floodgate is separated buckle 19 lockings, and switch knob 18 and closing coil 17 all can not be closed a floodgate.Triping of circuit breaker tripping device 15 stoped the various possibilities of breaker closing with the locking of switch knob 18 and closing coil 17, guaranteed the fail safe of isolator operation.
After isolator operation finishes, chain controlling organization 1 should be allocated to " service position " B, circuit breaker could close a floodgate.Behind breaker closing, the connecting lever of chain controlling organization 1 inserts chain stop pin 52 in the chain locking ring 54 of drive rod 3, and with chain locking mechanism 5 lockings, handle can not be operated, thereby has stoped isolating switch by misoperation.
The utility model has successfully been avoided isolating switch on-load separating brake, combined floodgate and the arc short-circuit phenomenon that causes, has reduced the generation of accident, uses safer, reliable.
