Definitions

  • the invention relates to an insulating material housing for a modular, multi-pole low-voltage protective switching device, having a front side, a fastening side arranged opposite the front side, and narrow and broad sides connecting the front and the fastening side, the insulating material housing being designed in a narrow design and having a first and has a second functional area, which are arranged next to one another with a width of only one pitch unit and each extend from one narrow side to the opposite narrow side, each of the two functional areas having a wide and a narrow partial area. Furthermore, the invention relates to a low-voltage protective switching device, which has at least two modules arranged next to one another, each with an insulating material housing formed according to the invention.
  • Electromechanical protective switching devices for example circuit breakers, miniature circuit breakers, residual current circuit breakers and arcing or fire protection switches - are used to monitor and protect an electrical circuit and are used in particular as switching and safety elements in electrical energy supply and distribution networks.
  • the protective switching device is electrically conductively connected to an electrical line of the circuit to be monitored via two or more connection terminals in order to interrupt the electrical current in the respective monitored line if necessary.
  • the protective switching device has at least one switching contact which can be opened when a predefined state occurs—for example when a short circuit or a fault current is detected—in order to separate the monitored circuit from the electrical mains.
  • Such protective switching devices are also known as series installation devices in the field of low-voltage technology.
  • Circuit breakers are specially designed for high currents.
  • a circuit breaker which is also referred to as a “miniature circuit breaker” (MCB)
  • MBC miniature circuit breaker
  • Circuit breakers and miniature circuit breakers guarantee safe shutdown in the event of a short circuit and protect consumers and systems from overload, for example from damage to the electrical lines due to excessive heating as a result of an excessive electrical current. They are designed to automatically switch off a circuit to be monitored in the event of a short circuit or if an overload occurs and thus to separate it from the rest of the line network.
  • Circuit breakers and miniature circuit breakers are therefore used in particular as switching and safety elements for monitoring and protecting an electrical circuit in electrical power supply networks.
  • Miniature circuit breakers are from the publications DE 10 2015 217 704 A1 , EP 2 980 822 A1 , DE 10 2015 213 375 A1 , DE 10 2013 211 539 A1 or EP 2 685 482 B1 known in principle.
  • a single-pole circuit breaker To interrupt a single phase line, a single-pole circuit breaker is usually used, which usually has a width of one pitch unit (corresponds to approx. 18mm).
  • three-pole miniature circuit breakers are used, which accordingly have a width of three modular widths (corresponds to approx. 54mm).
  • Each of the three phase conductors is assigned a pole, ie a switching point. If the neutral conductor is also to be interrupted in addition to the three phase conductors, this is referred to as a four-pole device, which has four switching points three for the three phase conductors and one for the common neutral conductor.
  • compact miniature circuit breakers which, with a housing width of just one pitch unit, provide two switching contacts for one connecting cable each, i.e. either for two phase cables (compact miniature circuit breakers of type 1+1) or for a phase cable and the neutral conductor (compact miniature circuit breaker of type 1+N).
  • Compact protective switching devices of this type with a slim design are known, for example, from publications DE 10 2004 034 859 A1 , EP 1 191 562 B1 or EP 1 473 750 A1 known in principle.
  • a residual current circuit breaker is a protective device to ensure protection against a dangerous residual current in an electrical system.
  • a fault current - which is also referred to as differential current - occurs when a live part of the line has an electrical contact to earth. This is the case, for example, when a person touches a live part of an electrical installation: in this case, the current flows as a fault current through the person's body towards earth. To protect against such body currents, the fault current circuit breaker must quickly and safely disconnect all poles of the electrical system from the mains when such a fault current occurs.
  • FI circuit breaker short: FI switch
  • DI switch residual current circuit breaker
  • RCD Residual Current Protective Device
  • mains voltage-dependent and mains voltage-independent device types While mains voltage-dependent residual current circuit breakers have control electronics with a trigger which, in order to fulfill their function, rely on an auxiliary or mains voltage, mains-voltage-independent residual current circuit breakers do not require an auxiliary or mains voltage to implement the tripping function, but usually have a somewhat larger summation current transformer to implement mains-voltage-independent tripping, which means that a larger induction current can be generated in the secondary winding.
  • the size of the current in a line leading to an electrical load is compared with the size of the current in a line leading back from the electrical load, for example a neutral conductor, using a so-called summation current transformer .
  • This has a ring-shaped magnetic core through which the primary conductors (return electrical lines) are passed.
  • the magnetic core itself is wrapped with a secondary conductor or a secondary winding.
  • the sum of the electrical currents flowing to the consumer is equal to the sum of the electrical currents flowing back from the consumer.
  • the currents become vectorial, ie directional or signed, added, it follows that the signed sum of the electric currents in the forward and return lines in the fault-free state is equal to zero: no induction current is induced in the secondary conductor.
  • no induction current is induced in the secondary conductor.
  • the sum of the electrical currents flowing in or out which is recorded in the summation current transformer, is not equal to zero.
  • the resulting current difference causes a voltage that is proportional to the current difference to be induced at the secondary winding, as a result of which a secondary current flows in the secondary winding.
  • This secondary current serves as a residual current signal and, when a predetermined value is exceeded, triggers the protective switching device and as a result—by opening the at least one switching contact of the protective switching device—the correspondingly secured circuit is switched off.

Furthermore, the insulating material housing has a first functional area and a second functional area, which are arranged next to one another with a width of only one pitch unit and each extend from one narrow side to the opposite narrow side, each of the two functional areas having a narrow and a wide partial area.

  • the narrow sub-area of one functional area and the wide sub-area of the other functional area complement each other to form a housing width of one pitch unit.
  • components of the low-voltage protective switching device that have a width of more than half a pitch unit, for example a magnetic short-circuit tripping device, in the respective functional area. This allows better use to be made of the installation space that is scarce in the case of compact switchgear.
  • the first functional area serves as a current path area, which is provided and designed for this purpose Include switch contact and a magnetic and a thermal tripping system to interrupt the switch contact.
  • the first functional area has appropriately dimensioned accommodation spaces for all components and assemblies of a miniature circuit breaker (MCB): the switching contact with the associated switching mechanism, the magnetic and thermal tripping system, an arc quenching chamber to extinguish an arc that occurs when the energized switching contact opens, and two Connection elements for contacting the low-voltage protective switching device with the electrical phase line to be monitored (mains side and load side).
  • MCB miniature circuit breaker
  • the functionality of a miniature circuit breaker can be arranged entirely in half a pitch unit, with space-saving components such as the thermal tripping system being arranged in the narrow sub-area of the first functional area, while large-volume components such as the magnetic tripping system or the arc quenching chamber are to be arranged in the wide sub-area of the first functional area are.

  • the second functional area can also be used in other ways, i.e. for arranging components to implement additional functions.
  • the second functional area is provided and designed to accommodate a further functional assembly.

  • the first and second functional areas are separated from one another by a partition.
  • the partition wall runs from one narrow side to the other and is oriented at least in sections parallel to the two broad sides of the insulating material housing. It serves to isolate the two functional areas - in particular the live components that can be arranged therein.
  • the insertion opening can be closed on both sides.
  • the two plug-in openings can be closed to provide electrical insulation for the components in the installation space and to protect against environmental influences such as moisture and/or dust.
  • covers or flaps can be used as a closure element, which can be fastened to the insulating material housing by means of suitable fastening means—for example snap hooks or film hinges.
  • the insulating material housing has an assembly opening which is arranged transversely to the insertion opening and extends from the fastening side into the installation space. Better access to the installation space can be achieved with the aid of the assembly opening, for example in order to connect the component to be arranged in the common installation space with other components arranged in the interior of the insulating material housing.

  • the modular low-voltage protective switching device has at least two modules arranged next to one another, each with an insulating housing formed according to one of the preceding claims, with the installation spaces of the at least two modules arranged next to one another forming a common, cross-module installation space for accommodating a cross-module functional assembly.
  • the two insulating housings forming the low-voltage protective switching device are arranged side by side, so that the installation spaces of the two insulating housings are directly adjacent to one another and in this way form a common, cross-module installation space in which a large-volume functional assembly can be arranged.
  • a summation current transformer is accommodated and held in the installation space spanning the modules.
  • a summation current transformer for example, through which a neutral conductor and at least one phase conductor are routed, can be considered as a large-volume functional assembly. In this way it is possible to mount the summation current transformer towards the end of the assembly sequence when the half-shells of the two insulating housings are already closed.
  • the assembly work - which is due in particular to the threading through of the comparatively rigid primary conductors through the magnetic core of the summation current transformer - can be significantly reduced as a result. Since the primary conductors are outside the Insulating material housing, and thus passed through the magnet core before the assembly of the summation current transformer in the insulating material housing, the assembly of the low-voltage protective switching device can be carried out at least partially automatically.
