Definitions

  • the present invention relates to a cabinet for electrical panel having improved functions and characteristics. It is known that cabinets for electrical panels are specifically designed and manufactured so as to meet the functional and installation requirements of the components that constitute the panel. In particular, in order to meet these requirements, cabinets are generally produced according to a parallelepipedal structure inside which an adequate space is delimited which is suitable to accommodate the components of the panel; the framework of said structure constitutes a chassis that is suitable to structurally support the various components operatively connected thereto, such as for example electrical and/or electronic devices, guides or supporting plates, cladding and/or protection panels, doors for opening/closing said electrical panel, et cetera.
  • the frameworks of cabinets are produced in several parts, generally constituted by elements that are arranged substantially horizontally and are known as cross-members and by vertically arranged elements or posts; said elements are furthermore mutually connected by appropriate connection means, such as for example corner joints.
  • the panels for cladding the electrical panel and an opening/closure door are then connected to the resulting framework.
  • the connection among the various parts of the framework and between said framework and the cladding panels is generally provided by means of welds or by using fixing means, for example screws, or by using both types of connection.
  • these solutions are not ideal, both as regards production and as regards the assembly of the various parts.
  • the aim of the present invention is to provide a cabinet for electrical panel that allows to obviate the drawbacks of the prior art and in particular lends itself to a significant simplification of production steps and to a reduction of the associated costs.
  • an object of the present invention is to provide a cabinet for electrical panel in which the operations for mutually assembling the various parts are reduced and facilitated with respect to the known art.
  • Another object of the present invention is to provide a cabinet for electrical panel that allows an overall reduction in the number of its constructive components, with a consequent benefit from the economic point of view and a reduction in the number of inventory codes to be managed.
  • a cabinet for electrical panel characterized in that it comprises: — at least a first containment module, which comprises a base wall, a top wall, a rear wall, two side walls, and a front wall provided with a first opening, said first containment module forming a first volume that is suitable to accommodate components of the electrical panel; ⁇ at least a second containment module, which comprises a base wall, a top wall, a rear wall provided with a second opening, two side walls and a front wall, said second containment module forming a second volume that is suitable to accommodate additional components of the electrical panel; said first and second modules being mutually connected so as to overlap at least partially said first and second openings and put in communication said first and second volumes.
  • Figure 1 is a perspective view of the cabinet for electrical panel according to the invention
  • Figure 2 is a bottom view of the cabinet of Figure 1
  • Figure 3 is a schematic front view of the rear wall of the second module of the cabinet according to the invention
  • FIG 4 is a front view of the front wall of the first module of the cabinet according to the invention.
  • the cabinet for electrical panel according to the invention generally designated by the reference numeral 100, comprises at least one first containment module 1 and a second containment module 2, which are mutually connected in the manner described hereinafter and are configured so as to form respectively a first volume and a second volume that are suitable to accommodate components of the electrical panel, for example capacitors, circuit breakers, et cetera.
  • the first module 1 is obtained from a single folded and punched metal plate, and comprises a base wall 3, a top wall 4, a rear wall 5, two side walls 6 and 7, and a front wall 8 provided with an opening 9, which are arranged so as to form said first volume for accommodating the components of the electrical panel.
  • the front wall 8 of the module 1 has a frame 17, shown in dashed lines in Figure 1, that runs substantially along an entire rim formed by the top wall 4, by the two side walls 6 and 7, and by the base wall 3, transversely to said rim, and perimetrically delimits the opening 9.
  • the second module 2 is in turn obtained from a single folded and punched metal plate and comprises a base wall 10, a top wall 11, a rear wall 12 provided with an opening 13, shown schematically in Figure 3, two side walls 14 and 15 and a front wall 16, arranged so as to form said second volume for accommodating additional components of the electrical panel.
  • the front wall 16 of the second module 2 is also open and is configured so that it is coupled to a door 30 for opening/closing the cabinet 100; the door 30 is provided with at least one window 31 for accessing the electrical panel, which is generally arranged so as to mate geometrically with a component of the electrical panel, for example a power factor control.
  • the rear wall 12 of the module 2 has a frame 20, which is wider than the frame 17 of the first module and lies substantially along an entire rim formed by the top wall 11, by the two side walls 14 and 15 and by the base wall 10, transversely to said rim, and delimits perimetrically the opening 13; holes 21 are furthermore provided in the frame 20 and are arranged along two opposite sides of said frame 20 along two corresponding rows that are substantially parallel to each other. Said holes 21 allow the fixing of at least one plate, not shown, for mounting the components of the electrical panel; clearly, the arrangement of the holes on the frame 20 might be changed appropriately according to the various requirements of application.
  • the cabinet 100 furthermore comprises a flat element 22 which has a quadrilateral front cross-section and which, in the embodiment shown in Figure 1, is arranged along the line that connects the base wall 10 and the top wall 11 of the second module 2 and is fixed to two mutually opposite sides of the frame
  • the element 22 can be provided separately with respect to the module 2 and be connected thereto subsequently, for example by welding, or can be provided monolithically therewith; furthermore, it is possible to use a structural stiffening cross-member, shown schematically in Figure 1 and designated by the reference numeral 28, whose two opposite ends are connected respectively to the flat element 22 and to the rear wall 5 of the first module 1.
  • the cabinet 100 comprises a covering element 32, which once the modules 1 and 2 have been mutually coupled in the manner described hereinafter, is fixed to the top walls 4 and 11 and forms above them a free volume meant to accommodate the fans for the forced ventilation of the components of the electrical panel.
  • the covering element 32 is constituted by a single part that is shaped substantially like a square wave and has first and second end edges 34, which are mutually opposite and are fixed to the top walls 4 and 11, and an intermediate portion 35, which mutually connects the end edges 34.
  • Said portion 35 has a first part that protrudes at right angles from an edge 34, a second part that is perpendicular to the first part, and a third part that connects the second part to the second edge 34 and is perpendicular thereto; furthermore, on the portion 35 there is an opening 36 for the passage of the conductors meant for connection to the components of the electrical panel.
  • the covering element 32 is fixed to the top walls 4 and 11 advantageously by utilizing the screw coupling of eyebolts 33, typically used for optionally lifting and moving the cabinet 100, without having to resort to additional fixing means and to the corresponding operations.
  • pins 37 for grounding the structure are provided on various parts of the cabinet 100.
  • the two modules 1 and 2 are arranged so that the front wall 8 of the module 1 and the rear wall 12 of the module 2 rest against each other, so as to at least partially overlap the opening 9 and the opening 13 and put in communication the two volumes for accommodating the components.
  • the connection between the two modules occurs by mutually fixing, by virtue of conventional fixing means, the frame 17 and the frame 20, so that the fixing holes 21 are free from the encumbrance of the body of the frame 17, by virtue of the greater width of the frame 20 with respect to said frame 17, and so that the two modules are mutually aligned with respect to an external view of the cabinet.
  • the constructive solution with two modules according to the invention in fact allows a significant simplification of production steps, a considerable reduction in the number of required constructive components and of the corresponding inventory codes and reserves to be managed, and therefore allows ultimately a great advantage from an economic point of view.
  • the presence of the two modules provided with the frames 17 and 20 and of the corresponding accommodation volumes allows to utilize in an optimum manner the space available for the components of the electrical panel.
  • the presence of the element 22 entails additional advantages, since it allows to increase the number of plates that can be used and therefore also allows to increase the usable surface and to adopt various constructive configurations. For example, it is possible to use four plates, two of which are fixed to one row of holes 21 and to a row of holes 23, the other two plates being fixed to the other row of holes 23 formed on the opposite side of the frame 20 and to the second row of holes 21. Furthermore, with this solution it is possible to use plates that are smaller than those normally used in the known art, and this facilitates the bench wiring of the components with the plate and the subsequent installation of said plate in the cabinet on the part of the operators.
  • the covering element 32 allows to form, with respect to the top wall of the cabinet, a space that is suitable to accommodate the fans for forced ventilation, ensuring in any case, by virtue of its shape and particularly by virtue of the presence of the portion 35, their adequate covering and protection, for example from the action of external agents, such as drops of water that otherwise might seep and enter the panel.
