Definitions

  • the present invention relates to an automatic switch with actuating electromagnet for short circuits.
  • a switch of this type is formed by a casing made of insulating material and having a generally parallelepipedal shape, with two broader parallel faces or sides and smaller faces corresponding, with reference to the installation conditions, to a rear face, a front face, an upper face and a bottom face.
  • the body or casing is formed by two half-shells joined together in a plane parallel to the sides and houses the various mechanical and electrical components.
  • the rear face of the body is intended for mechanical installation of the switch on the support and has a recess for receiving a support rail onto which the switch is secured by means of sliding teeth arranged on the rear wall.
  • the components for manual operation of the switch are located on the front side, and a first and second clamp for securing external electrical terminals emerge on the bottom side and top side, respectively.
  • the sides of the switch must be flat, without raised areas preventing the adjacent arrangement of several modules, and must not have apertures for access to internal components, except for those necessary and specifically designed for establishing a mechanical interconnection between adjacent modules.
  • the essential components forming part of a switch of this type which must be able to interrupt high-intensity currents, including currents in the region of several tens of amperes, include a rapid-action electromagnet for automatically opening the switch in the event of a major overload due in particular to a short circuit.
  • the electromagnet must be constructionally simple, easy to install within the body and must have optimum characteristics in terms of reliability and operational repeatability.
  • the modular dimensions of the body must have compact dimensions, in particular in the direction perpendicular to the sides of the switch, and at the same time must not give rise to significant voltage drops or losses in the copper and the iron which are the cause, under normal operating conditions (variable depending on the load), of local heating which may alter the operating characteristics of the electromagnet itself or of the other devices present in the switch, such as, for example, the bimetallic thermal protection system for preventing prolonged overloads.
  • the need for compact dimensions is difficult to reconcile with the need for a rapid opening action which requires a suitable magnetic force of attraction associated with a significantly long working stroke of the armature or the movable core and, essentially, a kinetic energy acquired as quickly as possible and sufficient to actuate the mechanism for tripping and opening the switch.
  • the magnetic circuit is composed of a first fixed cylindrical core portion, integral with a yoke for closing the flow, and a second movable cylindrical core portion, axially aligned with the first portion and separated therefrom by an air gap.
  • a hollow cylindrical plastic cap which is force-fitted onto the first core portion, acts as an axial guide for the movable portion, which is freely inserted inside the cap, and with its closed end forms a bearing stop against which the movable core is pushed by an actuating stem, freely passing inside an axial cavity of the fixed core, and in turn biased or, in other words, "polarized” by a helical compression spring which is also housed in said cavity.
  • a helical winding of conducting wire with a relatively thick circular cross-section (2-2.5 mm) for exciting the electromagnet.
  • the object of the present invention is to provide an automatic switch with actuating electromagnet for short circuits, which has structural and functional characteristics such as to overcome the abovementioned drawbacks described with reference to the known art.
  • an automatic switch comprising, housed in an insulating shell, manual setting and resetting devices, opening and closing contacts actuated by said manual devices, tripping devices for automatically opening said contacts and a rapid-action electromagnet for activating said tripping devices when an overload occurs, characterized in that said electromagnet, which is of the movable core (plunger) type, consists of:
  • the present invention overcomes the drawbacks of the known art, is able to satisfy the abovementioned requirement and provides an automatic switch which is simple and inexpensive to produce and is provided with an electromagnet for protection against short circuits which is safe, reliable, fast and effective for a vast range of currents, and which results in minimal additional losses and at the same time has small dimensions in the direction perpendicular to the sides of the switch.
  • the structure of the electromagnet allows, without diversification of the components during production, the preparation, during final assembly, of modular switches of the same type having different operating characteristics.
  • the structure and the internal ribbing of the two half-shells fit together in a suitable manner and precisely position the two half-shells, with respect to each other, as well as the various components housed in the casing relative thereto and to each other.
  • the two half-shells are fixed together by means of screws or rivets passing through holes 2,3,4,5,6 perpendicular to the plane of the drawing.
  • the modular switch shown is provided with a recess 7 on the rear side for receiving a DIN standard rail onto which it is fixed by means of toothed slides, not shown.
  • a plurality of mechanical and electrical components is housed and precisely positioned inside the casing, in particular:
  • thermo protection device bimetallic strip 10
  • magnetic protection device electromagnet 11
  • the electric arc which is produced with the opening of the contacts passes from the contact 17 onto the arc guiding electrode 21 and is extinguished in the deionizing cell.
  • opening of the contacts must be particularly rapid. This is achieved by means of a relatively powerful spring which is tensioned by the manual setting lever and part of the tripping device.
  • This energy is provided by means of excitation of the electromagnet 11, owing to the effect of the short-circuit current.
  • the structure of the electromagnet 11 is shown in detail in the exploded view in Figure 2.
  • the electromagnet comprises a magnetic core consisting of a first fixed portion 25 and a second movable portion 26 which are aligned with each other in an axial direction.
  • the prism-shaped and non-cylindrical core has, perpendicularly with respect to the axial direction, a rectangular cross-section (having in a preferred embodiment, by way of guidance, side dimensions of 3.5 x 8 mm) with slightly rounded edges and is partially housed in a tubular aligning and guiding element 27 which also has a rectangular cross-section and is made by means of extrusion or moulding of plastic, for example with a thickness in the region of 0.3-0.4 mm.
  • the fixed core portion has, in the axial direction, a cylindrical through-hole 28 with a diameter in the region of 1-1.4 mm, inside which an actuating thruster 29 made of a low-conductivity, metallic or plastic, non-magnetic material is freely inserted.
  • the fixed core portion 25 has an annular groove 30 with sides perpendicular to the core axis for fixing, by means of engagement, into a yoke 31.
  • the yoke 31 is formed from a strip of ferromagnetic material with a cross-section of, for example, in the region of 7 x 1.5-2 mm folded so as to form a rectangular frame with dimensions of about 20 x 16 mm and a height equal to the width of the strip (7 mm).
  • a recess 32 for joining, by means of engagement, with the end recess 30 in the fixed core 25 is formed in one of the shorter sides of the yoke.
  • the opposite side of the yoke has, formed in it, a rectangular recess 33 for housing one end of the tubular guide element 27 which is arranged, in a similar manner to the core portions housed therein, inside the yoke, with the smaller dimensions oriented in the direction of the heightwise extension of the frame.
  • the shorter side of the yoke, where the recess 32 is present, has fixed to it, by means of electric spot welding, a metal end-piece 16 for supporting the fixed contact of the switch, said end-piece also being provided with a recess 34 which is superimposed over the recess 32 for joining, by means of engagement, to the fixed core portion.
  • the tubular element 27 has, arranged on it, a winding 35 formed by means of a preferably flat conducting wire having a rectangular cross-section (by way of guidance, 2.4 x 1.3 mm) and folded so as to form substantially rectangular turns with the smaller thickness of the copper oriented perpendicularly with respect to the axial direction of the core.
  • the winding is completely housed inside the yoke with a dimension, in the direction of the heightwise extension of the yoke, not greater than its height.
  • Suitable recesses 36, 37 in the yoke 31 allow, without an increase in the dimensions, the ends 38, 39 of the winding to pass outside the yoke so as to be fixed, respectively, by means of soldering, to the metal end-piece 16 provided, for this purpose, with a flange 40 which extends beyond the end of the yoke, and to the terminal 9 (Fig. 1) of the switch.
  • the electromagnet structure is completed by a torsionally operating helical spring 41 with a working arm 42 hinged in a hole 43 formed in the end of the movable core 26 opposite that adjacent to the fixed core 25.
  • the function of the spring is to bias or "polarize" the movable core 26 into the rest position and to oppose the plunging force which is exerted on the latter when the electromagnet winding has, passing through it, currents which fall within normal operating conditions and therefore do not cause opening of the switch.
  • the internal ribbing inside the casing forms a seat for the stable and precise positioning of the yoke and of the end-piece 16 integral therewith (and therefore of the entire electromagnet) as well as an abutment 45 against which the end of the movable core rests and thus exactly defines the rest position relative to the fixed part and, consequently, the width of the air gap in the rest condition.
  • the helical recall spring 41 is pivotably mounted on a pin 46 which may be formed integrally with the casing (or, if it is a separate component, fixed inside the casing in a predefined position) and with its working arm 42 pushes the movable core against the abutment surface 45.
  • the force exerted by the spring depends on its pretensioned condition: this is set by fixing the end 47 of the spring in a suitable position by means of engagement in a notch formed inside the casing so that this produces a predefined angle of winding of the spring with respect to its rest configuration.
  • the casing may be provided with several notches, such as 48, 49, so as to cause the spring 42 to assume one of several possible pretensioned conditions, which may be selected during assembly, so as to define one of various working capacities of the switch, which is generally expressed in amperes (for example 15-25 50 A) .
  • the recall means could also be structured in another manner, for example as a lever pivotably mounted on the pin 46 and wholly equivalent to the arm 42 and which is biased or “polarized” by means of an extension spring which is attached, on one side, to the lever and, on the other side, to a pin or notch (including one of several pins or notches) suitably arranged in the free space available between the manual setting device (13, 14) and the electromagnet 11.
  • the abutment 45 instead of being integral with the casing, may consist of a strip having a thickness defined as a function of the capacity, which is inserted into a seat in the casing.
