Definitions
- All switching devices that protect people and / or things from dangerous effects of the to protect electrical current such as residual current circuit breakers, Miniature circuit breakers, main circuit breakers, motor circuit breakers, Circuit breakers and the like contain triggers that are fault currents or overloads or Detect short circuits and then switchgear if limit values are exceeded trigger. Thereupon the main current contacts of the switching devices open, so that normally no harmful electricity can flow.
- a forced device is known Disconnect mains or main power lines, using a working memory that is a force provides along a path and that by means of a ratchet in an inactive Condition is maintained, with a shutter release with little effort triggerable and thus the RAM can be released so that it from the inactive in passes its active state, one driven by the working memory Disconnect device in the triggered state, the forced separation of the network or Main power lines.
- the invention is based on the object in the event of failure of the Switching devices mentioned above, in particular for residual current circuit breakers, a Device for the forced and very quick disconnection of the associated network or Show main power lines, in order to endanger people and / or things to exclude.
- the particular advantage of the device according to the invention is that it is direct in circuit breakers of the type mentioned at the beginning or as an additional device with these in series can be arranged.
- circuit breakers with suitable conventional Current measuring systems in particular measured the fault, overload or short-circuit currents and these measured values are also used by the device.
- Exceed the measured values a predetermined limit value and the respective circuit breaker does not switch within a certain time, the network or Main power lines separated. So basically the existing regular fails Protection function of the switchgear for different reasons, so the Device easily reliable and within a certain harmless Time the live lines. This forced separation of the lines is normal a unique and irreversible process, so that after that at least the circuit breaker or the switching device must be replaced and the device reactivated.
- a spring accumulator is provided as the working memory interacts with a lever lock and a fuse wire as a trigger.
- a compression spring 2 and above a piston 3 with a Tappet 3.1 arranged, which represent the essential parts of the spring accumulator.
- This biased position of the compression spring 2 (as already shown in Fig. 1) is by means of a Lever 4 attacking and anchored to the housing 1 fuse wire 5 reliably held.
- the device according to FIG. 2 is designed in a similar manner.
- the mainspring is in the range of The knee levers 4 'which engage the spring eyelets and are arranged in the interior of the spring, as in FIG shows. So that the toggle lever 4 'its almost extended position and thus the spring tension can maintain, it is also locked by a fuse wire 5.
- This is with One end preferably attached to the toggle joint and the other end to the Shell surface of the housing held and led out.
- Another tension spring 6, whose direction of action and points of attack roughly correspond to the position of the fuse wire, supports the latter in his task.
- the tension spring 6 is considerably weaker designed as the tension spring 2 '. Nevertheless, the tension spring 6 relieves the fuse wire 5 considerably, so that it can be made much thinner than in Embodiment according to Fig. 1. Its operation is analogous here also applicable, that is after the destruction of the fuse wire 5 by one Tripping current drives the tension spring 2 'the plunger 3.1 and this ultimately one Separator.

- a toggle lever serves as Spring accumulator in turn a compression spring 2 against the toggle lever 4 'via the piston 3 the bottom of the housing 1 is clamped.
- the almost stretched location of the as a ratchet attacking above the piston and supported on the top of the housing The toggle lever 4 'is again secured by the fuse wire 5, which is also here together with a tension spring 6 prevents the knee lever from buckling.
- the This device also functions in the manner already described.
- a device which, in contrast to the previous arrangements has a latch.
- Compression spring 2 arranged as a working memory, which is tensioned by the piston 3.
- the pestle 3.1 there is a recess into which a bolt 7 engages, which is located on the top supports the housing 1 and thus locks the plunger in the position shown. Also stops a fuse wire 5, the bolt 7 in engagement with the plunger recess, while one on Tension spring 7.1 engaging the bolt against the holding force of the fuse wire tried to unlock.
- This device operates in the manner already described, that is, according to The spring 7.1 pulls through the melting wire 5 due to a tripping current the bolt out of the recess of the plunger 3.1.
- the inactive position of the Working memory canceled and then under the action of the compression spring 2 the plunger 3.1 upwards and drives a separating device for forced separation of the power lines.
- the device can be provided with a pressure accumulator as a working memory be as shown by way of example in FIGS. 5 and 6. Doing so will result in the accumulators Working medium - preferably air - kept compressed and at first by a locking mechanism prevented the expansion.
- FIG. 6 The construction of the device according to FIG. 6, in which one chamber of the Housing 1 for receiving the compressed working medium 8 through a valve 9 is closed.
- the valve is loaded by a compression spring 9.1 in the opening direction also held against this force by a fuse wire 5, so that the chamber remains tightly sealed with the compressed working medium.
- a piston 3 with the plunger 3.1 is arranged in the valve chamber. After a Destruction of the fuse wire 5 by a trigger current opens the valve 9 under the Effect of the compression spring 9.1 and the working medium 8 can escape into the valve chamber. From there it flows under the bottom of the piston 3, which thus carries out the working stroke and again actuated a separating device with the plunger 3.1.
- the device according to FIG. 7, in which the main memory is used, is significantly different in design is designed as a pyrotechnic gas generator and is automatic, that is without one actual locking mechanism, is in the inactive state.
- This device is in the housing 1 a fuel 8 'arranged with a primer 8.1 and through a gas permeable Wall 1.1 of the housing included towards the piston 3. If a trigger current on the Given the primer, the fuel 8 'is activated and a gas volume is generated. This flows under the bottom of the piston 3 and drives it together with the plunger 3.1 upwards in order to include one of the separation devices described below actuate.
- 8 to 15 separating devices of various types are shown. So be 8 contacts 10 and 11, which in the course of a network or Main power line 12 are connected in series, pressed together by spring force. In front the contacts a wedge-shaped insulating body 13 is arranged, which is part of the Plunger 3.1 can be one of the working memories already described. In the case of one over The isolating body 13 is triggered and main memory initiated forced separation immediately pressed between the contacts 10, 11 and opens them.
- the network or main power line 12 in the course of the corresponding circuit breaker, not shown forcibly interrupted.
- switching contacts 14, 15 are shown schematically by a circuit breaker are arranged in series with the line to be protected. Should these switch contacts in Triggered case, for example, be welded, so they are only here indicated plunger 3.1 of the working memory forced open. On In this way, the forced interruption of the mains or main power lines can be done directly in the switchgear.
