Definitions
- the invention relates to a control panel for a circuit breaker, with a control surface and a retrofittable device for closing, covering and designing control elements.
- the push buttons for "ON” and “OFF” are normally located in the central area of the control panel of a circuit breaker.
- the standard design is such that efforts are made not to use separate operating elements, since these lead to increased manufacturing and cost expenditure, but rather to design the elements in the switching mechanism on which the operator has to move, that they also serve as a handling area. This is generally sufficient for standard designs. However, there are often increased requirements, for example with regard to the lockability of the operating elements, for protection against unauthorized operation. That is why the standard version of the circuit breakers already has additional controls that can be exchanged for another version if required or expanded with additional function groups.
- a circuit breaker of this type has become known through the DE catalog from Siemens: Protection equipment catalog NS1 1988, page 3/7.
- a cap can also be used as a locking device,
- WO 97/07519 proposes an arrangement in which a circuit breaker is provided with a locking device which has a safety lock to protect against unwanted switching on.
- a lockable protective device is attached in front of this security lock, which can only be locked when the key is removed.
- This protective device includes a cover plate in front of the security lock as well as a hinged flap hinged to the cover plate, which can be locked with a padlock.
- the protective member can be attached to a lock housing of the security lock, which protrudes above the level of the control panel. While this meets the requirement of securing the circuit breaker either with a safety lock or with padlocks, it does not allow the control elements to not only be locked, but also to be concealed or designed differently.
- the object of the present invention is therefore to provide a retrofittable device for the control panel of a circuit breaker, which offers the possibility of not only closing the control elements, but also concealing them or making them different, without making the standard version of the switch more expensive .
- a mounting plate which is easy to mount on the control panel, which forms the receptacle for all further functional groups and their variants and has two or more attachment options for additional elements within its base plate, with which Chen all possible applications can be combined as desired.
- the additional functions that go beyond the existing basic equipment can be pushbuttons, key switches, clap-flaps, locking devices for padlocks, permanent "OFF" commands and operation with a tool. In the embodiment according to the invention, these do not make the standard version of the low-voltage circuit breaker more expensive.
- the mounting plate can be attached in various ways. Fastening elements arranged on the mounting plate and engaging in the operating panel can be provided, or fastening elements located on the operating panel and engaging in the mounting plate.
- locking lugs can be arranged on the mounting plate for fastening the mounting plate on the operating surface of the operating panel and suitable counter surfaces behind which the locking lugs engage on the operating surface.
- small depressions can generally be provided in the user interface, which are then drilled out or material thinnings formed in the form of the cross section of the pastes, the inner parts of which can be broken out, as is generally known, for example, in installation boxes.
- the locking lugs are then designed so that they interact with the round drill holes or the correspondingly shaped cut-out openings, the distances and sizes of which are predetermined by the knockouts.
- the fastening elements are formed on the mounting plate so as to be to be inserted by means of a transverse securing ticket ⁇ or spring clip can be locked.
- Projections can also be provided on the control panel, the height of which corresponds at most to the thickness of the mounting plate and which have a threaded hole or an inserted metal internal thread. Then the mounting plate can be attached from the front using screws.
- the screws are then expediently provided with heads which, instead of a slot, have a stop for a screwdriver only in the fixed screw rotation direction and have an obliquely rising surface in the opposite direction of rotation, which means that they are only screwed in but not easily removed again can.
- other known screw locks are also conceivable, or screws that can only be screwed in and out using special tools.
- the mounting plate is assembled before it is installed.
- receptacles located on the mounting plate are provided, which are open towards the operating surface and into which existing brackets or pivot pins are hung on the additional elements to be installed. After installing the assembly plate this open side of the recordings is closed by the user interface.
- the mounting plate has openings in a cantilever which correspond to further fastening elements of additional elements which can be installed, for example in order to hang in a padlock in the case of closable pivotable additional elements or to accommodate hook-like extensions in the case of additional elements which are to be installed.
- the dome for actuators is in turn the basis for the assembly of various additional devices.
- a commercially available push button can be used, which then has a different appearance.
- it can be provided with a special label or a special color (yellow version for EMERGENCY STOP, in which the regular switch-on element remains in the ON position when triggered and only has to be reset to the OFF position before it is switched on again).
- a lock cylinder or another actuating element can also be installed in this dome.
- the dome for actuating elements consists of a rectangular box-like housing, which is open on one side, which, after installation on the mounting plate, faces the operating surface and has an opening of a suitable size for the installation of the actuating elements. On its upper part it has a holder for hanging in the receptacles of the mounting plate and on its lower part a hook-like extension for hooking into the openings in the projection of the mounting plate. It is therefore permanently attachable.
- the dome for tool actuation also consists of a rectangular box-like housing, which is open on the side facing the operating surface after installation on the mounting plate and has a small-diameter opening for the tool actuation on its front, through which only with a suitable tool can act on an actuating element covered with its help. He also has on its upper part a holder for hanging in the receptacles of the mounting plate and on its lower part a hook-like extension for hooking into the openings in the projection of the mounting plate and is therefore also securely attachable.
- the colored or transparent flap for permanent operation is designed to be locked and designed to be pivotable. It consists of a plate with a pressure piece arranged on the side facing the control panel, which has an axis-shaped pivot pin on its upper part for hanging in the receptacles of the mounting plate and a bracket with an opening for hanging a padlock on its lower part. If the built-in flap is pressed with the Dr ⁇ .c piece 1 '' onto an actuating element, for example a button, and then locked using a padlock through the openings in the projection of the mounting plate and in the bracket of the flap for permanent actuation, permanent actuation is required of the button, which can only be canceled after opening the lock.
- an actuating element for example a button
- the preferably transparent sealing flap is also provided for locking and is designed to be pivotable. It also consists of a plate which has an axis-shaped pivot pin for hanging in the receptacles of the mounting plate on its upper part and one on its lower part Shackle with an opening for hanging a padlock.
