Interlocking device 5 mechanically realizes the safety interlocking of fuse unit 2 and contact unit 1.This interlocking device 5 comprises a shelf bracket 51, a longitudinal tie 52, a link 53, a cross-tie 54 and a separating brake control piece 57, the corner part of shelf bracket 51 articulates by a pivot, the spring striker (not shown) of its vertical wall in fuse 21, longitudinal tie 52 upper ends have a pole 521, pole 521 rides on the horizontal wall of shelf bracket 51, thereby realizes being connected of shelf bracket 51 and longitudinal tie 52.The other end of longitudinal tie 52 is connected with a cross-tie 54 by a link 53, simultaneously, by this link 53, the longitudinal pulling force of longitudinal tie 52 is changed into the lateral pull of cross-tie 54, the other end of cross-tie 54 is connected on the separating brake control piece 57, and then is connected to the lower end of the actuator 432 of mechanical lock buckle assembly 43 by pull bar 441.This interlocking device also can further comprise a supporting plate 55 and extension spring 56, and supporting plate 55 is arranged in the fuse draw-in groove movably, and extension spring 56 upper ends are fixed, and the lower end is connected with supporting plate 55.
Contact arm 8 is connected with an end of the fuse 21 of fuse unit 2, and contact arm 7 is connected with the static conductive rod 132 of the vacuum interrupter 13 of contact unit 1.The front end of contact arm 8,7 has insulating contact respectively.
Below, in conjunction with the concrete structure of above-described combined electrical apparatus, the course of work of the present utility model is described.
The normality of this combined electrical apparatus is a gate-dividing state, and the moving conductive rod 131 of the vacuum interrupter 13 of contact unit 1 separates with static conductive rod 132.The bogie 41 of operating mechanism 4 is under the elastic force effect of tripping spring 45, and the end away from pivot on its horizontal wall 411 is upturned.
Closing operation.Referring to Fig. 1, when receiving reclosing command, closing coil 42 electric excitation, attract bogie 41 to clockwise rotate around pivot, make its horizontal wall 411 arrive horizontal levels.Rotation with bogie 41, the moving conductive rod 131 of the arc control device 13 of the contact unit 1 that is connected with the vertical wall 412 of bogie 41 moves right thereupon, simultaneously, the fixedly lock piece 431 that is fixed on the mechanical lock buckle assembly 43 on the lower surface of horizontal wall 411 of bogie 41 moves down with bogie 41.When the moving conductive rod in the arc control device 12 131 contacts with static conductive rod 132, realize closing a floodgate, simultaneously, the fixedly lock piece 431 and the actuator 432 of mechanical lock buckle assembly 43 snap together, and back-moving spring 442 compresses the lower end of actuator 432, makes mechanical lock buckle assembly 43 keep buckling state, to guarantee that this combined electrical apparatus still can remain on "on" position reliably after closing coil 42 outages.Then, the rupturing operation electric current makes closing coil 42 outages.
Sub-switching operation.Referring to Fig. 2.When receiving the separating brake instruction, switching winding 44 gets electric excitation, and pulling separating brake control piece 57 and pull bar 441 move to right, the lower end of pulling actuator 432, actuator 432 is rotated counterclockwise around pivot, simultaneously, the fixedly lock piece 431 of mechanical lock buckle assembly 43 and actuator 432 are threaded off.Then, under the Double spring effect of tripping spring 45 and touch spring, along rotating counterclockwise, the upper end of the vertical wall 412 of bogie 41 drives moving conductive rod 131 and moves to right bogie 41 around pivot, realizes separating brake.Under this state, even switching winding 44 outages, under the elastic force effect of tripping spring 44, bogie 41 still remains on this position, and moving conductive rod 131 is separated with static conductive rod 132, guarantees that separating brake is reliable.Then, the rupturing operation electric current makes the switching winding outage.
The interlocking action.By interlocking device 5 of the present utility model and chassis car interlock assembly 6, can realize the interlocking between contact unit 1 and the fuse unit 2, and the interlocking between contact unit 1 and the chassis car 3, thereby, make this combined electrical apparatus become an organic integral body.
Contactor can not carry out closing operation when fuse was undesired.Specifically, when arbitrary fuse 21 of fuse unit 2 is not installed or correctly is not installed in the fuse draw-in groove (not shown), the supporting plate 55 that is arranged on movably in the corresponding fuse draw-in groove moves under the tension of spring 56, the upper end of supporting plate 55 upwards promotes or upwards promotes pole 521 on the longitudinal tie 52 by shelf bracket 51, makes on the longitudinal tie 52 and moves.Longitudinal tie 52 is connected with cross-tie 54 by link 53, the longitudinal pulling force of longitudinal tie 52 is changed into the lateral pull of cross-tie 54.Because the other end of cross-tie 54 is connected to the lower end of the actuator 432 of mechanical lock buckle assembly 43 by separating brake control piece 57 and pull bar 441, so actuator 432 overcomes the back stretch of returning spring 442, makes mechanical lock buckle assembly 43 remain on this trip status.In this state, operating mechanism can't make contactor realize normal the combined floodgate.On the other hand, when contact unit 1 is in "on" position, if run into improper big electric current, fuse 21 will fuse immediately, and the spring striker (not shown) in the fuse 21 can stretch out, replace on the vertical sidewall of shelf bracket 51, shelf bracket 51 is pivoted, upwards promote the pole 521 of longitudinal tie 52, as mentioned above, the mechanical lock buckle assembly is threaded off, and then realize the separating brake of contact unit.
The "on" position jiggering of going to the bottom can not move.Specifically, when contact unit 1 is in "on" position, the horizontal wall of bogie 41 is horizontal, can depress the push rod 62 of the chassis car interlock assembly 6 on the base plate 12 simultaneously, the lower end of push rod 62 is pressed on the lockplate (not shown) on the chassis car 3, and restriction chassis car 3 can not move.If want mobile chassis car 3, necessary first separating brake moves push rod 62 under the elastic force effect of spring 63, no longer compress the lockplate on the chassis car 3, thereby removes the interlocking to chassis car 3.
By above-mentioned explanation as can be known, interlocking device 5 can realize the interlocked control between contact unit 1 and the fuse unit 2.Chassis car interlock assembly 6 can be realized the interlocking between contact unit 1 and the chassis car 3.
The protection action.When running into normally big electric current; fuse-link (not shown) in the fuse 21 of fuse unit 2 at first fuses; trigger the spring striker (not shown) action in the fuse 21; as mentioned above; drive interlock 5; make other phase separating brake that do not fuse of contact unit 1, thus the disengagement failure electric current, the protection power consumption equipment.
Below only enumerated a kind of embodiment of the present utility model, this execution mode only is for the utility model is described, and is not to be used to limit the utility model.Those of ordinary skill in the field utilize technological essence of the present utility model, all can do certain modification and accommodation to embodiment of the present utility model, and all these change, all within the protection range of claims that the utility model is carried
