Embodiment
The design of the utility model can be applicable to multiple electrical switchgear, such as but not limited to circuit breaker, network protector, change over switch.
With reference to figure 1, show control device 10 according to the circuit breaker of the exemplary embodiment of the utility model.This control device 10 can be attached to the circuit breaker (not shown).Circuit breaker can be a MCCB type circuit breaker (breaker of plastic casing).Circuit breaker can comprise handle, and this handle can be operated between ON (connection) and OFF (disconnection) position, makes contact operating mechanism wherein can engage and the fixed contact that separates the one or more phases that are used for circuit breaker, thereby is switched on or switched off circuit.Control device 10 can come switching on and off of operating breaker by means of motor driver 40.
Shown in Fig. 1-2 and Fig. 5-8, the control device 10 of circuit breaker comprises frame assembly or panel assembly 50.Side at frame assembly 50 is equipped with push button 1 and cut-off push button 2.Said push button 1 is respectively applied for the circuit that switches on and off circuit breaker with cut-off push button 2.Said push button 1 is associated with the controlling organization of control device 10 respectively with cut-off push button 2.Preferably, as shown in Figure 2, said controlling organization for example can be made up of three tie-rod/ pull bars 3,4,5, that is: first tie-rod 3, second tie-rod 4 and tertiary system bar 5.But should be understood that the quantity of said tie-rod is not limited to 3, but can become as required.As shown in Figure 2, below push button 1 and cut-off push button 2, be provided with corresponding connecting rod 21,22.Preferably, said control device 10 can also comprise selection mechanism 11.Manual mode, remote mode and the locking mode of circuit breaker can be correspondingly selected in this selection mechanism 11.Said selection mechanism 11 is installed on the frame assembly 50.Preferably, selection mechanism 11 is provided with at least one protruding tongue 25 (referring to Fig. 2), and it can be engaged in the respective slot of offering on the side of frame assembly 50 26 slidably.Selection mechanism also is associated with second tie-rod 4 of controlling organization, thereby cooperatively interacts with controlling organization.Each tie-rod of said controlling organization can be cooperated each other, makes the position that said connecting rod 21,22 can swing to corresponding to manual mode, remote mode and locking mode, thereby realizes function corresponding.
Particularly, as shown in Figure 2, first tie-rod 3 can be provided with groove 61 in its end.Connecting rod 21 can be engaged in the groove 61.Tertiary system bar 5 also can be provided with groove 63 in its end, and is provided with groove 62 at the opposite side of groove 63.Connecting rod 22 can be engaged in the groove 62.One end of second tie-rod 4 can be engaged in the groove 63, and the other end can match with first tie-rod 3.When said connecting rod 21 or 22 was swung to the position corresponding to locking mode or remote mode, the dropout of said tie- rod 3,4,5/tripping operation was moved disabled.Different therewith, when said connecting rod 21 or 22 is swung to the position corresponding to manual mode, the dropout campaign of said tie- rod 3,4,5 will be activated.Like this, under each pattern, said controlling organization can be launched the perhaps function of disable button 1,2.Should be understood that, cooperate the notch form that is not limited between each tie-rod and the connecting rod, other suitable fit form, for example backstop, form fit etc. can also be arranged.In addition, spring can also be set to cooperate the operation of controlling organization in the control device.For instance, spring 31 can at one end be associated with tertiary system bar 5, links to each other with frame assembly 50 at the other end.Spring 32 can at one end be associated with selection mechanism 11, and then is associated with second tie-rod 4, links to each other with frame assembly 50 at the other end.
With reference to figure 3, show the swing position 6 of the connecting rod 22 that is in locking mode and remote mode.With reference to figure 4, show the swing position 7 of the connecting rod 21 that is in manual mode.Therefore, under manual mode, only can control motor driver 40 with cut-off push button 2 through mechanically operating push button 1 locally.Under this manual mode, Long-distance Control is forbidden electronically/electrically, thereby can not remotely control motor driver 40.Under remote mode, only can remotely control motor driver 40.By means of the above-mentioned dropout campaign of under remote mode, forbidding the tie-rod of controlling organization, circuit breaker can not be realized the control to motor driver 40 with motor driver 40 related push button 1 or cut-off push buttons 2 through mechanically operating.Though these buttons can be pressed, they do not have any function under this remote mode.Under locking mode, the control to motor driver 40 under said manual mode and the remote mode is all disabled.Particularly, remote mode is by locking electronically/electrically.It is disabled that the manual control that realizes by means of mechanical button also is similar to the remote mode that kind.Preferably, under locking mode, the mechanical latching to push button 1 can be provided further, for example by means of mechanical lock.This can provide extra safety measure, has increased the protection for the circuit breaker accidental switch.Particularly, push button 1 can not be pressed it by mechanically locking.In addition, cut-off push button 2 still is similar to the cut-off push button under the remote mode, that is: it can be pressed, but its function is disabled.
Like this; The controlling organization of the control device 10 of the utility model can occupy a plurality of positions corresponding to manual mode, remote mode and locking mode; Make that under each pattern circuit breaker only can be realized operation or the control corresponding to corresponding modes, the operation under other pattern is disabled simultaneously.
In addition, the utility model also provides a kind of circuit breaker that comprises above-mentioned control device.This circuit breaker can be realized the standalone feature under the independent pattern by said control device, thereby local operation and remote operation are distinguished fully.By means of the utility model, the various states of circuit breaker can not be incorporated into together, make the operator can clearly distinguish each mode of operation of circuit breaker, thereby can not cause obscuring the drive pattern state.
Though at present preferably shown in the accompanying drawing with above-described embodiment, should be appreciated that such embodiment only provides by way of example.The utility model is not intended to be subject to any specific embodiment, and is intended to expand to the various remodeling that fall in the accompanying claims scope.Those skilled in the art will be apparent to other remodeling.
