Below in conjunction with accompanying drawing and by example utility model is described in further detail; but following example only is the utility model example wherein; do not represent the rights protection scope that the utility model limits, rights protection scope of the present utility model is as the criterion with claim.
Embodiment
According to Fig. 1 ~ Fig. 4 structure of the present utility model is described further.The interlocking device of this switchgear breaker chamber door comprises the bent plate 9 of locking a door that is fixed on the breaker chamber door, the parts such as interlocking device that are used for hooking the bent plate 9 of locking a door.Wherein interlocking device comprise be used to the rotatable hook plate 10 of locking a door that hooks the bent plate 9 of locking a door, with hinged " L type " connecting rod 6 in hook plate 10 ends of locking a door, with hinged " L type " pull bar 5 of " L type " connecting rod 6 one ends, with " L type " pull bar 5 other ends by promote the fastening following valve drive link 1 of axle sleeve 3, with following valve drive link 1 by hinged the last valve drive link 2 of fixed axis 2A, wherein " L type " connecting rod 6 one ends are fixed in the interlocking device and also can rotate around this stiff end.Following valve drive link 1 end is provided with and can promotes upper and lower valve drive link 1 around the circuit breaker pusher 4 of hinge fixed axis 2A rotation.Circuit breaker pusher 4 promotes valve drive link 1 rotation down, drives " L type " pull bar 5, the 6 interlocking motions of " L type " connecting rod successively, finally makes hook plate 10 rotations of locking a door hook the bent plate 9 of locking a door.Vertical direction in " L type " connecting rod 6 bights fixedly has a fixed head 8 that has an interlocking shaft 11, is provided with interlocking axle sleeve 7 at fixed head 8 and the interlocking shaft of locking a door between the hook plate 10.Also be provided with the preceding axle bed 12 that is fixed on the breaker chamber inwall in the interlocking gear end, at preceding axle bed 12 ground cutter operating axis 13 be set.Angle between the both sides of " L type " connecting rod is 60 °.(or 45 °)
The utility model operation principle: under the situation of closing the door, circuit breaker shaken to enter reach the service position, in shaking process into, promote promotion axle sleeve 3 collisions on the upper and lower valve drive link 2 of cabinets, 1 by circuit breaker pusher 4, driving upper and lower valve drive link 2,1 is the rotating shaft rotation with fixed axis 2A, last valve drive link 1 drives " L type " pull bar 5, " L type " pull bar 5 drives " L type " connecting rod 6, " L type " connecting rod 6 drives interlocking shaft 11 rotations that are installed in the interlocking axle sleeve 7, and the hook plate 10 of locking a door that is welded on the interlocking axle sleeve 7 rotates simultaneously.The hook plate 10 of locking a door is that rotating shaft is rotated counterclockwise with interlocking shaft 11, hooks the bent plate 9 of locking a door.Dynamic/static contact interlock, breaker closing, switch cubicle begins operate as normal.Thereby reality circuit breaker when the service position, guarantee the purpose that breaker chamber Men Buhui opens.
Circuit breaker is when the breaker open operation of service position, under the state of closing the door, circuit breaker is shaken out, circuit breaker pusher 4 is followed outwards movement of circuit breaker, dynamic/static contact separately, when promotion axle sleeve 3 spins off from 4 li mouths of circuit breaker pusher, the release of the stage clip power about utilizing in the valve drive link 2,1, upper and lower valve drive link 2,1 returns to initial condition gradually, and dynamic/static contact is separated.Last valve drive link 1 drives pull bar 5 to move downward clockwise, and an end of pull bar 5 pulling connecting rods 6 is that the other end of center of circle drivening rod 6 and the hook plate 10 of locking a door move downward simultaneously with interlocking shaft 11 simultaneously.When circuit breaker was got back to test position fully, the hook plate 10 of locking a door broke away from the bent plate 9 of locking a door, and the breaker chamber door is opened.When circuit breaker shook back test position, the chamber door can be opened, and be safe condition this moment.
