Definitions
- main switches or switching devices with isolating properties are required.
- these must reliably signal the disconnection of the system from the supply either by means of a visible isolating distance or by a display which reliably indicates the switching state of the device. Above all, they must allow a barrier that prevents accidental switching on safely. In addition, an increased dielectric strength must be ensured via the switching point. Also, predetermined leakage currents must not be exceeded.
- IEC 60947-2 and IEC 60947-3 are described, for example, in IEC 60947-2 and IEC 60947-3. These standards are implemented in electrical equipment such as disconnectors, load disconnectors, fuse disconnectors and circuit breakers with disconnecting function and similar devices.
- Electromagnetic switching devices according to the above-mentioned prior art meet these requirements.
- the US-A-5,844,186 describes an arrangement with which a conventional contactor can be used as a circuit breaker.
- the object of the present invention is to provide a further generic electromagnetic switching device.
- the additional device is adjacent to the base unit on a side of the device, which is perpendicular to a direction of displacement of the contact bridge carrier.
- the switching device is structurally particularly simple.
- the locking element receptacle can alternatively be open on both sides or only on one side.
- the locking element is held captive in the auxiliary device, no separate element is required to block the contact.
- the locking element to the attachment in particular to a possible locking element, be adapted. Tolerances are therefore previously known or can be minimized.
- auxiliary device has an additional switch which can be looped into a circuit via which the electromagnetic drive device can be acted upon by the starting current, a power supply of the electromagnetic drive device to the switching device can be interrupted,
- auxiliary switch When the auxiliary switch is arranged and configured to open when mechanically blocking the contact it can not happen that accidentally opening the coil circuit is omitted.
- connection between additional device and basic device can alternatively be solvable or insoluble. At least when mechanically blocked in the disconnected position contact the accessory should be inextricably linked to the basic unit.
- connection between the basic device and the additional device is particularly easy if the auxiliary device is locked to the basic device.
- an auxiliary switch housing is connectable to the switching device, in which an auxiliary switch is arranged, which can be actuated by the contact bridge carrier together with the contact, the switching device is even more flexible.
- the auxiliary switch is connected to the contact bridge carrier preferably without play. Alternatively, the connection may be direct or indirect.
- a basic unit 1 of an electromagnetic switching device is exemplified as a contactor.
- the contactor has, among other things, an electromagnetic drive device 2, an armature 3, a contact bridge carrier 4 and, as a rule, several electrical contacts 5.
- an electromagnetic drive device 2 an armature 3
- a contact bridge carrier 4 for the sake of clarity, only one contact 5 is shown in FIGS. 1 and 2.
- Each contact 5 consists in the rule of two fixed contact points 5 'and a movable contact bridge 5 ".
- the electromagnetic drive device 2 has a coil 2 'and a coil core 2 "The coil 2' can be acted upon by a drive unit 6 with a starting current I.
- the armature 3 is attracted and thereby the contact bridge carrier 4 and with it the contact bridge 5 "transferred to a bridging position, in which the contact 5 is closed. This state is shown in FIG.
- the contact bridge carrier 4 and with it the contact bridge 5" are transferred by means of a return spring in a release position in which the contact 5 is opened. This position is shown in FIG. The return spring is not shown for clarity sake.
- the contact bridge carrier 4 is moved when transferring from the disconnected position to the bridging position and vice versa in a direction of displacement x.
- an additional device 7 adjoins the basic device 1.
- the additional device 7 adjoins a device side to the base unit 1, which is perpendicular to the direction x.
- the additional device 7 is also part of the electromagnetic switching device. It is connected to the basic unit 1, z. B, locked.
- the attachment 7 has an extension 8 for the contact bridge carrier 4.
- the extension 8 is connected to the contact bridge carrier 4 - preferably free of play - so that the extension 8 is forcibly guided by the contact bridge carrier 4.
- the attachment 7 has a continuous, that is open on both sides, Arretierelementam 9, the extension 8 a corresponding recess 10.
- a locking element 11 - here z. B. the bracket 11 of a padlock 12 - are manually passed through the Arretierelementam 9 therethrough.
- a shut-off element 13 here the closing element 13 of the padlock 12
- the locking element 11 is in the disconnected position of the contact bridge carrier 4 is closed off with the auxiliary device 7 (or the switching device) connected.
- the locking element 11 is in the Arretierelementam 9
- the extension 8 and with it also the contact bridge carrier 4 and the contact 5 are mechanically blocked in the release position.
- These elements 4, 5, 8 thus remain in the disconnected position even when the electromechanical drive device 2 is acted upon by the attraction current I.
- the insertion of the locking element 11 in the Arretierelementability 9 can be made apparent in fully assembled switching device.
- connection of the auxiliary device 7 with the base unit 1 is detachable. Preferably, however, it is insoluble, at least when the contact 5 is mechanically blocked in the disconnected position. In most cases, it is even advantageous if the additional device 7 is permanently connected permanently to the basic device 1.
- the switching device has an additional switch 14, which is arranged in the additional device 7.
- the additional switch 14 is looped according to the Figures 1 and 2 in a circuit through which the electromagnetic drive device 2 with the attraction current I can be acted upon. It is also apparent arranged and designed so that it interrupts the circuit during insertion of the locking element 11 in the Arretierelementaid 9, ie the mechanical blocking of the contact 5. An accidental switching on the electromagnetic drive device 2 with blocked contact bridge carrier 4 is thus not possible. Any possible damage due to a long-lasting high current load of the coil 2 'are thus avoided.
- FIGS. 3 and 4 essentially correspond to the embodiment according to FIGS. 1 and 2.
- an auxiliary switch housing 15 is placed on the auxiliary device 7 on a side opposite the basic device 1 and connected to the auxiliary device 7.
- the auxiliary switch housing 15 may be latched to the attachment 7, for example.
- an auxiliary switch 16 is arranged in the auxiliary switch housing 15.
- the auxiliary switch 16 is actuated by the contact bridge carrier 4 together with the contact 5.
- the auxiliary switch 16 Because of the distribution of the switching device in the base unit 1 and the auxiliary device 7, the auxiliary switch 16 from the contact bridge carrier 4 only via the extension 8 and thus indirectly actuated. With a corresponding one-piece design of the switching device but also a direct operation would be possible. In any case, the auxiliary switch 16 but should be operable from the contact bridge carrier 4 without play.
- the locking element receptacle 9 is only open on one side. Furthermore, in the embodiment according to FIG. 4, the locking element 11 is permanently connected to the auxiliary device 7. For this purpose, the locking element 11 and the Arretierelementability 9 cooperating holding and locking elements 17, 18, by means of which the locking element 11 is held captive in the auxiliary device 7. According to FIG 4 corresponds to one of the holding and locking elements 17, 18 an actuator for the additional switch 14. The actuator for the additional switch 14 but could also be a separate element.
- the electromagnetic switching device can thus be easily extended by separator properties.
