Definitions

  • the invention relates to a switching system, in which in each case a number of switch elements are combined in a switch module having a predetermined power input side and power output side,provided with input and output terminals of the switch elements.
  • Such a switch system is known from EP 0 219 570.
  • This system comprises a switch module having three switch elements and a terminal module.
  • the switch module has an input side and an output side provided with terminals for connecting the switch elements.
  • the terminals could be connected to incoming and outgoing leads by means of clamping devices in the terminal module, said devices pressing the switch elements terminals to the associated leads.
  • a switching system is housed in a switchbox, the switch elements of the switching system being grouped in switch modules.
  • the switch elements are switch contacts which comprise at least a fixed and a movable contact, or cartridges or a combination thereof, although the invention is suitable for any type of switch element.
  • the switch contacts for the R, S and T phases are combined in a group or switch module, optionally supplemented by the neutral conductor.
  • the switch contacts are placed in the switch module with their main directions parallel to one another, so that, in general, the location of the input and output sides of the module is determined by the orientation of the switch contacts and the location of the terminals thereof. In general, therefore, the incoming leads and outgoing leads will be located in the extension of one another and run parallel to or in line with the main direction of the switches.
  • connections which are not in line with the main direction of the switch contacts but where, for example, the input and/or output cables or rails run perpendicular to the said main direction.
  • the power input and/or power output side is not in the vicinity of the terminals of the switch contacts, whilst the plane thereof is also not perpendicular to the main direction of the switch contacts but can run parallel thereto.
  • the cables which in the case of high currents are of large diameter, are installed they must be bent between the power input and/or power output side and the terminals of the switch contacts so that the cable lugs fixed to the ends of the cables can then be fixed on the appropriate terminals of the switch contacts.
  • the connections are at 90°.
  • the aim of the invention is to provide a switching system of the type mentioned in the preamble, with which a flexible choice of the position and orientation of the input and/or output side is possible and installation work is simplified. Furthermore, the aim is for as complete as possible utilisation of the available space in the switchbox and of the nominal load of the switch module.
  • connection module is added to the switch module which connection module has four sides, each side being arranged for receiving terminals for connecting incoming and outgoing leads and that the connection module is provided with connecting conductors for connecting the input and/or output terminals of the switch module to the terminals provided on at least one of the sides of the connection module.
  • the switch module is provided with connecting conductors, said module can be regarded as an adapter, by means of which the desired connection can be produced, that is to say the normal connections to the switch elements can be brought to the desired position via the adapter.
  • the desired connection can be produced, that is to say the normal connections to the switch elements can be brought to the desired position via the adapter.
  • 90° connection only three connecting conductors are needed for a three-phase power supply.
  • the invention has the advantage that the production line is simplified because fewer components are needed. Stocks can be reduced because one switch module can be used with one connection module in several terminal configurations and there is therefore no need to keep a separate switch module in stock for each individual configuration.
  • the invention also offers the advantage of simple assembly because only the connection module has to be adapted for a specific terminal configuration.
  • connection is simplified by the freedom in the direction of connection. Moreover, the required space for non-standard connection directions is reduced and no derating has to be employed. An additional factor is the reduction in price as a result of modularity and, consequently, the less expensive production and stockholding.
  • the European patent application 0 188 258 discloses a switch housing or module having terminals for connecting cables.
  • the connection of a side termination is possible by bending the terminal connections.
  • the terminal connection 77, 78 and 79 are provided at one side of the switch housing.
  • These terminal connections are floating, because of which there is a risk of short circuit between said connections.
  • additional space is required at one side of the switch housing for the bending of the terminal connections.
  • this prior art switch housing has no connection module, so that the terminal connections are floating.
  • a further difference should be seen in the position of the conductors of the connection module according to the invention.
  • the conductors of the connection module according to the invention are bent in the space under the switch housing and such that the plane of bending remains within the respective dimension of the switch housing.
  • T-shaped contact for a distribution pillar.
  • Two kinds of T-shaped contacts are suggested, one having a downwards extending socket for receiving an electrical connection of a cable and the second one having an upwards extending socket. Because the T-shaped contact is reversible four positions of the sockets, left downward, left upward, right downward and right upward are possible. This flexibility has nothing to do with the situation as described in the present patent application with switch elements and the connection with cables or busbars running perpendicular thereto.
  • connection members 30, 32 on the support 16 of a switch 10 By positioning the connecting members perpendicular mounting directions are possible, however, both directions are in the plane of the switch 10, in particular one of the directions is downwards . Also in this prior art solution no connection module is used.
  • the connecting conductors can be insulated cables, but preferably the connecting conductors are in the form of electrically conducting connecting bars. Said bars can be of circular or rectangular cross-section and can be manufactured in the factory, it being possible to apply an extensive degree of standardisation. The aim of said standardisation is to select the shape of the conductors in such a way that a minimum number of standard conductors can suffice.
  • the conductors to be used can be chosen in accordance with the requirements of the customer and fitted in the connection module. At the time of installation all that is then necessary is to connect the cables to the connection and/or switch module, without bending being necessary.
  • connection module has a housing of insulating material and the connecting bars are arranged on the base of the connection module housing, electrically insulated from one another.
  • the base of the connection module housing is provided with an upright partition of insulating material, by which means the base is divided into two regions, it being possible for the connecting conductors running essentially perpendicular to the main direction of the switch elements to the associated power input or power output side to be arranged in the one region and for the connecting conductors to the opposite side to be arranged in the other region.
  • the base of the connection module housing is provided with a number of upright partitions of insulating material to form channels in which connecting conductors can be laid.
  • connection module is provided with terminal modules on the power input and the power output side.
  • At least one of the terminal modules consists of a screw terminal module for clamped connection of a connecting conductor and corresponding cable conductor.
  • a preferred embodiment of the screw terminal module comprises an outer housing inside which an electrically conducting inner housing is movably accommodated, the distance of movement being greater than the thickness of the connecting conductor and a plate, which is movable in the same direction as the inner housing by means of a screw which is supported in the outer housing and can be screwed in and out, being accommodated in the inner housing for simultaneously clamping a cable conductor between the plate and the wall of the inner housing facing said plate.
  • the associated terminal modules are made up of a plug terminal module for connecting the switch element or a connecting conductor to the power rail.
  • the plug terminal module can be a spring contact which engages around the rail, but the plug terminal module is preferably accommodated in a housing of insulating material which is a snap fit on a wall of the connection module and in which knife or scissor contacts are located for accommodating the power rail between them in a clamping manner.
  • the switching system comprises switch elements, of which in each case a number, in general three, are combined or grouped to form a switch module.
  • the switch elements can be, for example, switch contacts, cartridges, a combination thereof or other elements having a switch function.
  • a system of this type comprises the switch contacts for the phases R, S and T, the switch contacts of which are, for reasons of clarity, not shown in Figures 1a-1f. However, the terminal points R1, R2, S1, S2, T1 and T2 of the switch contacts of the three-phase system are shown.
  • the switch contacts are combined to form a switch module of three sets of switch contacts, to which a connection module 1 has been added.
  • the main directions of the switch contacts in Figures 1a-1f are in the direction of R1-R2, etc.
  • the terminal points L1a, L2a and L3a of the cables have to be made in line with the main direction of the switch contacts, few problems are experienced in practice.
  • customers purchasing the switching system, and installers have a requirement not only for the conventional connections which are in line with the main direction of the switch contacts but also for a facility for making connections which are not in line with, but at an angle of, for example, 90° to the said main direction. Examples of the latter are shown in Figs 1b-1f.
  • the terminal points L1b, L2b and L3b shown at the bottom of the connection module 1 are in line with the main direction of the switch contacts. Said terminal points are located, for example, on the power input side.
  • the power output side is in this case on the left side of the connection module 1.
  • the terminal points L1a, L2a and L3a of said power output side are connected, by means of the connecting conductors 2, which are drawn diagrammatically and in broken lines, to the respective terminal points R1, S1 and T1 of the switch contacts.
  • the terminal points L1a, L2a and L3a of, for example, the power input side are shown at the top of the connection module 1 and are connected to the terminals R1, S1 and T1 of the switch contacts.
  • Fig. 1c the terminal points L1b, L2b and L3b of the power output side, which are connected to the terminals R2, S2 and T2 of the switch contacts, are arranged on the right-hand side of the connection module 1.
  • the connecting conductors 2 between the terminals R2, S2 and T2 of the switch contacts and the terminal points L1b, L2b and L3b of the power output side on the right-hand side of the switch module have been drawn in broken lines.
  • both the power input side and the power output side have been chosen such that they are at 90° with respect to the main direction of the switch contacts.
  • the connecting conductors 2 are shown in broken lines. It is pointed out that the power input side can be the power output side, and vice versa.
  • connection module 1 is to be regarded as an adapter.
  • the direction of connection can be freely chosen when connecting a switching system in a switchbox, without the cables which have to be connected for the various phases having to be bent or the switching system having to be turned.
  • a saving in space is achieved because no account has to be taken of the size of the radii in the bends of the cables.
  • the connection module is thus a highly advantageous solution with which both connections in line with a main direction of the switch contacts and connections at 90° are possible without any problem.
  • the switch module also has the abovementioned advantages for the manufacturer and the user, as well as for the installer and/or customer.
  • the neutral conductor is not shown in Figs 1a-1f and it is clear that more configurations are possible with said neutral conductor, and especially when the sequence of the connections L1, L2 and L3 can be changed, as can be seen from Figures 1e and 1f.
  • Figs 2 and 3 show an embodiment of a part of a switching system according to the invention.
  • Said part consists of a switch module 3, in which the switch contacts 4, 5 and 6 for the three-phases have been combined or grouped.
  • the switch contacts 4, 5 and 6 have been arranged with their main directions parallel to one another.
  • the connecting conductors for the connection of the terminals R2, S2 and T2, which are located on one side of the switch contacts 4, 5 and 6, to the power side 8 are shown as pre-formed connecting strips 9, 10 and 11.
  • said conductors can also be cables or connecting conductors having a circular cross-section.
  • connection module 1 Said connecting strips 9, 10 and 11 are arranged such that they are insulated from one another, for example by means of air, on the base of the connection module 1 made of insulating material and are fixed to said base by screws 30.
  • the connection module 1 has two side walls 12 and 13, but can also have a side wall on the remaining sides.
  • the base of the connection module 1 is provided with a partition 14 made of insulating material, which runs diagonally and has been cast as an integral whole with the connection module 1. Said partition 14 divides the base into two regions.
  • the partition 14 is to be regarded as a plane of symmetry of the connection module 1. The effect achieved by introducing symmetry is that when it is desired that the power side 7 is not at the top of the connection module 1 in Fig.
  • connecting conductors of the same shape as the connecting conductors 9, 10 and 11 can be used for the connection to the terminals of the switch contacts at the other side thereof.
  • Fig. 5 The number of different connecting conductors has been reduced as a result of this measure, which is advantageous from the standpoint of production engineering and for stockholding.
  • Terminal modules 18, 19 can be arranged at the end of said short terminal strips 15, 16, 17. Connection of the cable ends to the terminal strips 15 and 16 is effected by means of the screw terminal modules 18 and 19. Connection of a cable to the terminal strip 17 can be effected by means of a cable lug and screw. Of course, the screw terminal modules 18 and 19 are preferable to said cable lug and screw connection.
  • connection strips 9, 10 and 11 are likewise provided with terminal modules 20, 21 and 22. Because cable lugs in general take up a great deal of space, an appreciable saving in space is achieved by the use of the terminal modules in which the exposed cable ends can be connected directly to the strips, because said narrow side 8 of the connection module 1 does not have to be made wider.
  • connection module 1 Should it be desired that the power side 8 must be at the opposite side of the switch contacts, it will be possible to use the same connection module 1, it then being possible to turn the connection module 1 through 180° with respect to the switch contacts.
  • Figs 4 and 5 show an embodiment in which both the power input side and the power output side are oriented in a direction perpendicular to the main direction of the switch contacts 4, 5 and 6 of the switch module 3.
  • the connecting strips 9, 10 and 11 for connecting the terminals R2, S2 and T2 of the switch contacts 4, 5 and 6 to the terminal modules 20, 21 and 22 are shown on the power input side 8 of the connection module 1.
  • the connecting strips 23, 25, 26 are arranged on the base of the connection module 1, one end of said strips being connected to the associated terminals R1, S1 and T1 of the switch contacts, whilst the free ends thereof are provided with the terminal modules 27, 28 and 29.
  • the connecting strips 9, 10 and 11 are fixed to the base of the connection module 1 by means of screws 30, and the connecting strips 23, 25 and 26 are fixed to the base of the connection module 1 by means of screws 31.
  • the connecting strips 9/26, 10/25 and 11/23 are identical to one another and the latter are electrically insulated from one another with the aid of the partition 14, instead of by means of air.
  • FIG. 6 A further embodiment of the invention is shown in Figs 6 and 7.
  • the switch contacts 4, 5 and 6 are combined to give a switch module 3, to which a connection module 1 has been added.
  • the base of said connection module 1 is provided with partitions 32 to 36, as a result of which the connecting strips can be placed closer together and the whole is kept more compact. Symmetry is maintained in this embodiment as well, so that the number of different connecting strips has been restricted to a minimum, i.e. three.
  • the connecting strips 23, 25 and 26 are connected at one side to the terminals R1, S1 and T1 of the switch contacts 4, 5 and 6 at one side thereof, whilst the free ends of said connecting strips are provided with the terminal modules 27, 28 and 29.
  • the strips 23, 25 and 26 are fixed to the base of the connection module 1 by means of screws 31.
  • the effect achieved by the use of the partitions 32, 33 and 34 of insulating material is not only a more compact construction, but also that the connecting strips are never able to make contact with one another even when subjected to rough treatment, whilst the position of the connecting strips is also more or less fixed at the time of assembly.
  • terminal modules 37, 38 and 39 are used, which are slid onto the wall 13 and fixed thereto by means of, for example, a snap fitting connection.
  • the modules 37, 38 and 39 which are constructed as plug terminal modules, clamp around the rails and provide the electrical connection between the rails and the terminals R2, S2 and T2 of the switch contacts.
  • Fig. 8 shows a possible embodiment of a plug terminal module 56.
  • Said module 56 comprises the contacts 57 and 58 for clamping around a rail.
  • the clamp contacts 57 and 58 merge into a body 59 which has the flat parts a, b and c.
  • the body 59 is connected to the lip 61, in which there is a hole 60 which serves for connection to a terminal point of an associated connecting strip of the connection module or a terminal point of the associated switch contact.
  • Said plug terminal module can be arranged or fixed directly on the connection module.
  • said fixing can also take place by means of a block 62 made of insulating material, which is provided with snap fitting elements, which are not shown, which interact with snap fitting elements of the connection module, which likewise are not shown.
