Specific embodiment
Fig. 1 shows the key diagram of module 100 according to the invention.In addition, device of rotation driving 200 is shown in FIG. 1 With under-voltage release 300.The handle 310 of electric switch by from the position " ON " into the position " OFF " or from the position " OFF " to The linear movement of the position " ON " is turned on or off electric current.Device of rotation driving 200 is converted to the rotation of rotational handle 10 The linear movement of the handle 310 of electric switch.Transmission device 220 and sliding block 230 can for example be arranged thus, sliding block 230 makes The handle 310 of electric switch moves.
Module 100 according to the invention is also shown in Fig. 1, and module 100 is mounted on device of rotation driving 200 and rotational handle 10 Between, and including auxiliary switch 110.In rotational handle 10 for example according to the arrow in Fig. 1 from the position " OFF " to the position " ON " Direction rotation in the case where, before reaching such as position " ON ", auxiliary switch 110 is first switched.
Auxiliary switch 110 can perhaps be switched to " not being manipulated " from " being manipulated " or from " not being manipulated " It is switched to " being manipulated ".
Auxiliary switch is operated due to for example just having switched switch in other words in advance before the position arrival " ON " 110, then for example can be by the circuit of under-voltage release 300 in switching electrical switches to the position " ON " by auxiliary switch 110 It is switched on before.
Module 100 according to the invention is also showed that in Fig. 2.Furthermore device of rotation driving 200 with shaft 210 is shown And rotational handle 10.It is disposed with instruction disk 500 between rotational handle 10 and module according to the invention 100, indicates disk 500 Indicate the position of the switch, such as position " ON ", " TRIP (tripping) " position or the position " OFF ".
Module 100 according to the invention also includes shaft 199, and shaft 199 is mechanically rotated the manipulation of handle 10 and machine Tool formula is arranged in the shaft 210 of device of rotation driving 200.
Module 100 according to the invention is further shown in Fig. 3.Here, module 100 includes module housing 180,181, Module housing 180,181 can for example construct in two style corresponding to Fig. 3.Auxiliary switch is disposed with inside shell 180,181 110.Module 100 further includes disc cam 150 and the control handwheel 160 with the coupling of disc cam 150.
Disc cam 150 and control handwheel 160 couple, so that before reaching one of position of the switch, auxiliary switch 110 It is switched in advance.Auxiliary switch 110 passes through the radial access of thickened section 155 on disc cam 150.Radial 155 quilt of thickened section Arrangement, to realize before reaching a position of the switch, such as position " ON " or the position " OFF ", auxiliary switch 110 is mentioned Preceding switching.
The coupling of disc cam 150 and control handwheel 160 can be carried out corresponding to view in Fig. 1.It is shown in FIG. 1, leads Seat 151 is arranged in disc cam 150, and pin plug 161 is advanced in the guide bracket 151, and pin plug 161 is mounted on behaviour On vertical disk 160.Therefore, the Pre-handoff of auxiliary switch 110 may be implemented in the length corresponding to guide bracket 151.
The coupling of disc cam 150 and control handwheel 160 carries out in which can also correspond to the view plug-in type of Fig. 6 A and Fig. 6 B. Disc cam 150 with radial thickened section 155 and 160 plug-in type of control handwheel are run mutually embeddingly each other, up to reaching determining Backstop, 160 sets of control handwheel are inserted in and are mounted in the shaft 210 of device of rotation driving 200.
Module 100 according to Fig. 3 further includes reset spring 170, and reset spring 170 makes disc cam 150 and control handwheel 160 Mutually in predefined positioning.
Be shown in FIG. 4 from upper left, upper right, the circulation of lower-left to bottom right for from the position " OFF " into the position " ON " Pre-handoff.Here, handle 10 is transformed into the position " ON " from the position " OFF ".For this purpose, the pin plug 161 of control handwheel 160 exists It advances in the guide bracket 151 of disc cam 150.It means that upper left and the first movement shown in upper right only make dish type in figure Cam 150 moves and switches auxiliary switch 110.The end of guide bracket 151 is reached corresponding to upper right view in Fig. 4 and is being realized auxiliary In the case where the switching for helping switch 110, the control handwheel 160 of switching device of rotation driving 200 is also moved.Corresponding to Fig. 4 In the case that lower-left reaches the position " ON ", electric switch is by 200 band of device of rotation driving into the position " ON ".Here, when turning When fixed handle 10 is unclamped by operator, reset spring 170 just for by 150 band of disc cam into predefined positioning and turn Fixed handle 10 indicates the position " ON " again.
The second auxiliary switch 120 is shown in FIG. 4, radial thickened section 150 is constructed so, so that two auxiliary switches 110, it 120 is switched in advance in systems.
The sequence converted from the position " ON " into the position " OFF " for electric switch is shown in FIG. 5.Here, auxiliary is opened 110,120 are closed also by corresponding Pre-handoff.
Method 100 according to the invention for switching electric switch is shown in FIG. 7.Here, according to the invention Device of rotation driving 200 is installed on electric switch, is mounted with module 100 according to the invention again on device of rotation driving 200 Together with rotational handle 10.Start 1001 and termination 1002 between, the method 1000 comprising steps of
Direction rotation 1010 by from rotational handle 10 a to position of the switch, so that at least one auxiliary switch 110,120 It is manipulated, and then
Rotational handle 10 is continued to rotate 1020 into the position of the switch.
For the reason of the space, it is often impossible to which auxiliary switch 110,120 is integrated in device of rotation driving 200.Together Sample does not consider to be integrated in auxiliary switch 110,120 in the box of compact type power switch for the reason of the space yet.
Module 100 according to the invention can be mounted between device of rotation driving 200 and rotational handle 10 by client.It is auxiliary Switch 110,120 is helped to be in module 100 according to the invention, the Pre-handoff for such as circuit of under-voltage release 300.
In order to be switched to the position " ON " from the position " OFF " in advance, module 100 has control handwheel 160 and disc cam 150. Client can install rotational handle 10 or shaft coupling on disc cam 150.Relative to control handwheel 160, disc cam 150 has There is idle running, which is for example realized by guide bracket 151 and the pin plug advanced in guide bracket 151 161.Equally, which can To be realized by the socket connection corresponding to the view in Fig. 6 A and 6B.By the idle running, disc cam can be relative to behaviour The determining corner of vertical disk deflection, without making the movement of control handwheel 160 and being thus switched electric switch.
This rotation is utilized, so that auxiliary switch 110,120 passes through radial thickened section 155 on disc cam 150 Switch in advance.By reset spring 170, disc cam 150 turns round again, makes the instruction of rotational handle 10 for compact with this The correct position of the switch of power switch.Auxiliary switch 110,120 can position in this wise, so that working as device of rotation driving 200 Rotational handle 10 when switching from the position " OFF " into the position " ON " or switching from the position " ON " into the position " OFF ", auxiliary Switch 110,120 is manipulated in advance.Furthermore, it is possible to be determined by normally opened contact in auxiliary switch 110,120 or normally-closed contact It is permanent to open ground or switch normally closedly.
