Definitions

  • the invention relates to a manually operated circuit breaker for motor protection and / or line protection.
  • Such circuit breakers essentially comprise a base assembly, a manual actuator, an electronic control unit, an actuator unit and a trigger.
  • a manual actuating device at least the switching mechanism is actuated via a rotary knob and via an actuating shaft, wherein the actuating device is accommodated in a housing part projecting to the operating front, and the actuating shaft is arranged perpendicular to the operating front.
  • the knob protrudes on the front and can preferably also be designed lockable.
  • circuit breakers As a circuit breaker such circuit breakers are known which are tuned in their tripping behavior (up to multiple starting current) to be protected electric motor, or serve as a circuit breaker to protect electrical lines or equipment against thermal overload or short-circuit damage.
  • the tripping behavior and thus the use of such circuit breakers are determined by the thermal and the short-circuit tripping values.
  • Examples of constructed according to the modular principle modular circuit breaker are in the DE 36 42 719 A1 or in the WO 01-27958 A1 described.
  • Another motor protection switch can also be equipped with replaceable overcurrent release module ( CH-PS 319019 ). In this case, an operator can set up different trigger modules, which differ in different current ranges or different inertia classes.
  • a trigger module should not be able to be pulled in the ON position of the circuit breaker.
  • a safety device provided in the form of a flap.
  • the window is designed such that the operating knob in the ON position engages over the edges of the window so that the shutter module can not be pulled out of the inserted position.
  • the safety device (the flap) is a very elaborately designed part.
  • a circuit breaker which can be modularly expanded by plugging replaceable add-on modules.
  • the circuit breaker has a prismatic housing part protruding toward the operating front, on which two contact surfaces and contact surfaces are formed perpendicular to the front panel.
  • the additional modules can be plugged directly into the circuit breaker in this prior art or they are separated from the circuit breaker on a base (mounting rail) attached.
  • a circuit breaker comprising a base assembly, an exchangeable protection and control device, and an electromechanical control module assembled with the base assembly.
  • the manual circuit of the circuit breaker by means of a fixedly attached to the control module or on the base assembly manual actuator.
  • circuit breakers In such and similar circuit breakers is disadvantageous that the modular assembly is possible regardless of whether the circuit breaker is in the ON position or not.
  • the invention has for its object to provide for a circuit breaker modular assembly with at least one replaceable control unit, on the one hand different features with the control unit are adjustable and on the other hand a backup function is available, where only under certain conditions, the exchange is possible.
  • the electronic control unit is designed as a module which can be plugged into the base module, and the electrical supply energy supplying the consumer is looped through the control unit.
  • the control unit also includes another protective function for the operation of the consumer protected by the circuit breaker.
  • the control unit (in particular in the form of its electronic circuit) draws its power supply and the detection data from the main circuit of the circuit breaker.
  • the electronic circuit is the center of the control unit.
  • the circuit is supplied as input and measurement signals via current transformers the parameters of the current flowing through the main current paths. The control unit thus always works when the circuit breaker at least one of the underlying consumers power. To insert the control unit on the base assembly contact means are present.
  • the control unit is set to specific control variables for an error case in which the circuit breaker has to turn off.
  • the settings can preferably also be changed by an operator to different control variables on externally accessible rotary knobs.
  • control variables the inertia of the cutoff and a fault current exceeding a certain rated current are primarily predetermined and / or adjustable. Such residual current criteria are also covered by international standards (EN 60947), where, for example, tripping times are assigned to different groups of rated currents.
  • EN 60947 international standards
  • the control unit activates the switching mechanism via the actuator unit, which causes the contacts of the main flow paths to open.
  • the core of the actuator is an energy storage, which causes the accelerated loading of the switching mechanism.
  • the circuit breaker may include a short circuit quick release, which has a mechanical operative connection also acts on the switching apparatus.
  • the circuit breaker with the described basic module forms a basic unit, in which the customer / operator can predetermine and / or change individual functional features by replacing the control unit and / or the trigger module.
  • circuit breaker may be pluggable in or on the base assembly, or otherwise assembled with the circuit breaker.
  • circuit breaker there is the advantage of a basic unit in which functions for use can be set in a simple and reliable manner or, if necessary, their values can be changed.
  • the control unit can be pulled before working on the electrical system or on an electric motor to be protected, with a visible separation point is formed and the cable is safely interrupted.
  • the power supply is expediently carried out via current transformers. It is of considerable advantage if the openings for the plug contacts are finger-proof and thus secured against unintentional contact.
  • the trigger can be equipped with a function in case of undervoltage.
  • one of the actuator which is designed as an operating knob or as an assembly manual rotary drive, operated locking device is provided which is formed on the actuating shaft and can be activated by rotation of the actuating shaft.
  • the locking device blocks in the ON position of the circuit breaker pulling the control unit.
  • the locking device consists of an acted upon by the actuating shaft and operable mechanical locking means which blocks the plug movement of the control unit or releases.
  • One advantage is that there is a secure lock against unauthorized or unauthorized changing of the control unit.
  • the locking device enters the path of the control unit to be inserted and blocks the movement of the control unit.
  • the locking takes place autonomously without additional operation from the outside by the rotation of the actuating shaft. By locking a secure fixation of the control unit is ensured with the circuit breaker. When switched on, the pulling of the control unit is blocked by the locking device activated by the locking device.
  • the control unit can only be removed and replaced when the circuit breaker is switched off.
  • the circuit breaker there may be a device for sealing a control unit inserted on the base module.
  • the manual actuator may be lockable. This means that the knob can be locked in the ON position of the switch with a lock. In such an arrangement, it is not possible to operate or turn off the knob in the ON position.
  • the figure relates to a circuit breaker, which is part of a mating switch combination whose components are designed according to the modular system.
  • the components of the kit are - as far as is relevant to the present application: the base assembly 100, which essentially comprises the contact apparatus 107 and the switching mechanism 140; the trigger module 120; the actuator unit (clamping unit) 110; the pluggable control unit 130 and the manual operating device.
  • the control unit 130 can be inserted on the switch housing adjacent to the projecting housing part parallel to the axis of the actuating rotary knob.
  • the mechanical Plug and separability is indicated in the figure by the dashed line 20.
  • contact means plug contacts 102,104
  • contact means plug contacts 102,104
  • contact means 134
  • the guide and connector elements cooperate with corresponding elements (receiving elements or contact sockets).
  • a separation distance between plug contacts and contact sockets It is advantageous if this separation distance is visible when the control unit is not plugged in.
  • input and output contacts main current paths, which may be in particular three-phase, and the contact apparatus 107 are indicated.
  • In the middle of the assembly arrangement is projecting a prismatic housing part with an operating front, which lies opposite the mounting surface.
  • the mounting surface is located on the back of the circuit breaker and serves primarily for mounting on a mounting rail.
  • the aforementioned housing part essentially comprises a device for actuating at least one switching mechanism (107) of the circuit breaker for opening and closing conductor paths (102, 104), which is manually operable with an actuating shaft 45 via an actuating rotary knob 150.
  • the actuating shaft 45 is arranged perpendicular to the front panel and the mounting surface (on the back of the circuit breaker). On the housing part, a connection surface for the plug-in control unit is formed perpendicular to the front panel.
  • the Anschfuss preparation has - not shown - linear guide elements and connector or contact means.
  • a contact 134 consisting of at least one contact pair to the actuator unit 110 is present.
  • the circuit breaker is operated on the operation knob 150, with which an OFF and ON position with a rotation of 90 ° is switchable.
  • the ON position the switching contacts 107 are closed.
  • the switch contacts of the circuit breaker can be manually opened by a first rotation of the drive shaft via the operating knob.
  • the drive shaft releases the switch lock in the switch drive mechanism and opens the switch contacts.
  • a short turn in the opposite direction is sufficient to operate the switch lock.
  • a full 90 ° turn is not required.
  • When automatically switching off in case of failure and opening the switch contacts forcibly drives the drive shaft. In the switched-off state of the circuit breaker, there are switching mechanism and switching contacts open, it is not possible to immediately put the circuit breaker in the on state.
  • the mechanical energy storage of the release module must first be tightened. For this purpose, with a left turn of the operating knob (and the drive shaft) from the OFF position by about 20 ° to 30 ° (ie in the opposite direction to the ON-switching movement), the trigger module is activated.
  • the individual components may be plugged into or onto the base assembly, or assembled in other ways. However, it is essential in connection with the claimed subject matter that the control unit 130 and the assembly manual rotary drive 150 are pluggable.
  • the trigger module 120 is preferably also designed to be exchangeable, wherein it can be inserted next to the prismatic housing part parallel to the axis of the actuating rotary knob.
  • the release module has plug contacts that can be plugged into corresponding contact sockets on the basic module. It is also essential that the control unit in the blocking state of the locking device can only be plugged in so far that there is still a separation distance between plug contacts and contact sockets, or in particular visible.
