摘要:
A switchgear cabinet closing device for locking a cabinet door on a switchgear cabinet. The closing device has a handle on which a closing mechanism is connected via an adjusting mechanism, whereby the handle is held on a housing mounted on an outer side of the cabinet door, and whereby the handle is secured in the lock position by a closing device. In order to adapt such a switchgear cabinet closing device to various closing systems in a simple manner, the housing has a primary housing for mounting the handle such that it can pivot, and a collar housing which can be connected to the primary housing. This invention also provides a collar housing that accommodates a lock of the closing mechanism.
摘要:
In a row of adjacent switchgear cabinets with a frame, vertical frame pieces of adjacent switchgear cabinets are connected to each other and the top and bottom sides of the frame are closed by upper and lower metal sheets which have edges at least on the sides facing each other. The edges are staggered in relation to the outer sides of the adjacent frame pieces and form a type of groove with the end pieces of the edges and/or the profiled sides of the horizontal frame pieces facing each other. The grooves in an area of the top and bottom metal sheets of the adjacent switchgear cabinets are protected from water penetration because they are sealed respectively in the area of the top and/or bottom metal sheets of the switchgear cabinets by a covering strip running from the front face to the rear face of the switchgear cabinet flush with the top and bottom metal sheets.
摘要:
A switching cabinet having a rack with an upper and lower frame and vertical and horizontal struts which are disposed horizontally. The upper and lower frame have corner cavities, to which vertical frame profiles can be connected. The vertical frame profiles have profiled segments which are turned towards an inside of the rack. Access to the inside of the rack is improved when the vertical frame profiles may be mounted or dismounted afterwards which can be done with few components and involves little effort during mounting by including vertical profiles on at least one side of the rack, whose ends and profiled segments can be inserted into the corner cavity from the outer side of the rack, and by placing and fixing the profiled segments onto the connector of a corner cavity.
摘要:
A rack for a switchgear cabinet, whereby the rack is assembled from frame legs, four of the frame legs being horizontally oriented forming a lower rack frame, which is connected to support profiles for bottom plates. The support profiles form a bottom frame (30), which has upward projecting fastening straps (50, 52). The frame legs (12 to 14) of the lower rack frame (11) have vertically aligned inner profile sides (21), which are provided with recesses (26) in the area of their lower edges (23) and of the adjoining profile sides for introducing the fastening straps (50, 52), and the fastening straps (50, 52) are screwed in place, resting on the inside of these inner profile sides (21) of the lower rack frame (11).
摘要:
An assembly rail for a switching cabinet, designed in a form of a stamped and bent part and having an assembly wall directed towards the inside of the switching cabinet. Lateral fixing devices, bent out of the assembly wall, are fitted with an assembly plate. Hooks are stamped and bent out of the assembly plate. The hooks can be inserted into fastening cavities of the vertical frame sections of the switching cabinet. The assembly rails can be firmly and easily secured to the frame sections with slotted fastening cavities if the hooks are bent out of the assembly plate around an axis of flexion extending in the longitudinal direction of the frame sections, if a protruding section of the hook is stamped out from the bending point and if a width of the hook is determined by the material thickness of the fastening plate.
摘要:
A switching cabinet which is enclosed by wall elements and a door. An assembly plate is placed parallel to a vertical side wall. The assembly plate can be moved in a direction of the associated side wall by sliders on at least one guide rail and brought into a position for mounting. Limited mounting opportunities, because of the guide rails, are thus avoided by designing the guide rails as a separate part, by providing positioning units which are detachably secured to the switching cabinet, and by being able to remove the guide rails from the cabinet after the assembly plate is positioned.
摘要:
A rack for a switching cabinet with a lower frame and an upper frame, which have horizontal length and width struts on which vertical frame sections can be arranged. The upper and lower frames are easy to produce and involve little technical complexity if the length and width struts are connected to form a continuous section in a single piece and the section is formed from a stamped and bent piece.
摘要:
A switchgear cabinet with a cabinet door and/or wall elements and a cover element covering the top, wherein a rain deflection device is disposed in the transition area between the upper horizontal edge of the cabinet door and/or the wall elements and the cover element. The removal of the collecting rainwater is possible with little structural effort in that in the transition area between the cabinet door and/or the wall elements and the cover element, a run-off channel is formed on the cover element or the cabinet door (wall element), and the cover element and/or the cabinet door (wall element) have guide devices, which guide the collecting water into the run-off channel.
摘要:
An operating unit with a housing for receiving an electrical or electronic circuit. The unit has vertical and horizontal lateral walls and a front wall. One or a plurality of laterally outwardly projecting handles for positioning the operating unit can be attached to the operating unit. The handle can be attached to the housing with little assembly effort and permits a user-friendly positioning of the housing. The handles can be profiled sections extending over at least a portion of the height or width of the lateral walls. The profiled sections are fastened on the housing in the area of the front edges formed by the front wall and the lateral wall. In the area of the front edges the profiled sections partially extend past the front wall and the lateral walls.
摘要:
An induction furnace (1) for melting and casting purposes has a closed crucible pot (2) with a pot bottom (3) and a cover (4), a crucible (6) housed in the crucible pot and surrounded by an induction coil (7), and an ascending tube (9) reaching into the crucible, through which the crucible can be emptied into a casting apparatus by means of gas pressure. To permit continuous operation and measurements and analyses during operation, the ascending tube (9) is fastened exclusively to the pot bottom (3) and connected with a horizontal delivery tube (11) which is brought through a side wall of the pot bottom (3). Furthermore, above a separation seam (24) between pot bottom (3) and cover (4) a turret (39) with a vertical axis of rotation is disposed, which has a charging air lock (26) for charging the crucible (6) with melt material (27) and a measuring chamber (36). The charging air lock and measuring chamber can be connected alternately with an air lock valve (25) which is disposed on the top of the cover (4).
