Definitions
- the invention relates to a service switching device according to the preamble of the claim 1.
- Such a service switching device is, for example, a selective protection switch, with a main current path, which is a series connection of a first main contact point, a striker system, a secondary contact point and a main bimetallic shutter includes.
- a generic service switching device has a parallel current path (selective circuit) arranged parallel to the secondary contact point on, a current-limiting resistor (selective resistor) and a second, thermal release (selective bimetallic release) acting on the switch lock wherein the main and / or the selective bimetallic release via a switching lock can open the second contact point, so that it is permanently opened.
- Selective shutdown means that "small" short circuit currents behind the downstream ones Circuit breakers occur and usually do not exceed 6kA, switched off by these and not by the generic selective circuit breaker should be. Only if after a certain time the "small" short-circuit current is not is switched off, the generic selective circuit breaker should turn off. "Size" Short-circuit currents that occur before the downstream circuit breakers and about 6kA and more, however, should from the generic Selective be switched off immediately.
- the main contact point is one, spatially close to the deionization chamber arranged, additional extinguishing chamber associated with additional extinguishing plates is, and the Deionmaschineshunt with the auxiliary extinguishing chamber, the secondary contact point and the impact anchor system are approximately in line in the area of the mounting plane the service switching device arranged; continues to be the main bimetallic shutter in the area of a front device narrow side approximately perpendicular to the mounting plane arranged, and the main contact point is in the range of the other front Narrow side, extending approximately perpendicular to the mounting plane, arranged.
- the service switching device will use the best possible space under consideration accessible to all prescribed thermal and electrical boundary conditions, so that a total of a generic service switching device with the inventive Arrangement of assemblies and components very compact and inexpensive can be produced.
- the individual assemblies and elements can each individually or in interplay be further developed advantageous yet.
- the additional extinguishing chamber can be made very small, they normally only the arc that may occur when switching the normal load current must take.
- the main bimetallic trigger may be a main bimetallic element and an additional lever, wherein due to the magnetic effect of the main bimetallic current, a force acts on the additional lever such that when a threshold value of the main bimetallic current of the additional lever is exceeded permanently opening the main contact point via the switch lock.
- a threshold value of the main bimetallic current of the additional lever is exceeded permanently opening the main contact point via the switch lock.
- the selective bimetallic actuator may comprise a U-shaped thermo-bimetal whose Bend perpendicular to the through the two legs of the U-shaped thermo-bimetal fixed bimetallic plane and perpendicular to the mounting plane of the service switching device he follows. This will make a short construction of the selective bimetal possible, nevertheless a large force can be applied. Because the partial forces each of the two legs of the U-shaped bimetal add up. Also this compact Construction of the selective bimetallic release contributes to the compact overall design at.
- the switch lock is arranged near the front front side. It can be used as a prefabricated module or from individual, in the device housing be built up parts.
- the detailed structure of the switch lock is not essential to the invention, moreover. With a handle that can be operated from the outside The main contact point can be permanently opened and closed via the switch lock become.
- the main bimetallic element, the U-shaped thermo-bimetal and the additional lever can be parallel to each other and in the area of a front narrow device in be arranged approximately perpendicular to the mounting plane. This also creates a spatial proximity of the three triggering elements to the near the front front arranged switch lock.
- the additional quenching plates can be in grooves in or as a pre-assembled additional splitter plate package be held on the housing inner wall. Their area is less than half of Deionticiansbleche.
- the rooms for the Deionmaschineshunt and the additional chamber can in a, in be formed about cuboid quenching chamber module body. This one is with his Broad sides oriented perpendicular to the mounting plane of the service switching device and by a parallel to the broad sides extending center partition into a Deionticians- subspace and shared an additional subspace.
- the Deionticiansbleche are located located in the deionization subspace, and the additional quenching plates are located in the additional subspace.
- deionization subspace and the additional subspace exhaust channels to the outside. These are between the back of the Deionmaschinesbleche or the additional quenching plates and the secondary contact remote from the rear Narrow side of the device by running parallel to the mounting level webs formed the center partition wall of the quenching chamber module body. Support the exhaust ducts a rapid pressure reduction in the Deionticianshunt by vortexing prevent.
- a further fluidic optimization can be achieved by inserting into the exhaust ducts, oriented perpendicular to the mounting plane, having a number of smaller holes Pinholes can be achieved.
- the thus optimized flow guidance contributes not insignificantly to a compact design of the overall device.
