Definitions

  • the present invention relates generally to a differential protection block which is usually used in association with a multipole circuit breaker.
  • a differential protection block which is usually used in association with a multipole circuit breaker.
  • Such a combination of a multipole circuit breaker and a differential protection block constitutes what is commonly called a differential circuit breaker.
  • a conventional differential protection block generally comprises a housing in which the various mechanical, electrical and electronic elements necessary for its operation are enclosed.
  • a housing in which the various mechanical, electrical and electronic elements necessary for its operation are enclosed.
  • a connection assembly constituting electrical conduction paths, one path being provided for each pole of the circuit breaker, a coil toroid intended to be mounted around said electrical conduction paths to detect a differential current.
  • a circuit breaker control mechanism for controlling a circuit breaker action in the multipole circuit breaker associated with said differential protection block, this control being effected in response to an electrical signal produced in said coil toroid.
  • a certain number of other elements can also be included such as an electronic control card, a power supply card, etc.
  • a major drawback of the differential protection blocks known up to now lies in the fact that the differential protection block must be fully assembled and connected to the multipole circuit breaker before it can be tested. If the test reveals a malfunction, it is difficult, if not impossible, to determine the source of the malfunction, because all the active elements of the protective block differential are enclosed in the housing of the device.
  • housings which are closed by means of non-removable devices for example rivets, gluing, hot deformation, etc.
  • disassembly of the defective differential protection unit is impossible, even for the sole purpose of identifying the cause of the malfunction.
  • An object of the present invention is to provide a differential protection block designed so as to be able to carry out tests before incorporating the active elements of said differential protection block into the housing of the device.
  • Another object of the present invention consists in proposing such a differential protection block also making it possible to be able to easily isolate the electronic parts contained in the differential protection block before carrying out dielectric tests on an electrical panel containing such protection blocks. differential.
  • the invention therefore relates in particular to a differential protection block associable with a multipole circuit breaker to constitute together a differential circuit breaker, this differential protection block comprising a connection assembly constituting electrical conduction paths for the different poles of the multipole circuit breaker, a toroid with reel intended for be mounted around said electrical conduction paths to detect a differential current and a trip control mechanism for controlling a trip action in the multipole circuit breaker in response to an electrical signal produced by said coil toroid.
  • the differential protection block further comprises a chassis on which said active elements are fixed by forming together a rigid functional sub-assembly; where it follows that said functional sub-assembly can be connected to the residual current device in order to be able to carry out a functional test of the functional sub-assembly while being able to access at least some of said active elements, said functional sub-assembly then being enclosed in said housing when said functional test has deemed it functionally satisfactory.
  • said chassis consists of a first molded plastic chassis part and a second molded plastic chassis part which can be coupled to the first chassis part.
  • said first and second chassis parts together form, in the coupled position: an envelope substantially completely surrounding a coil toroid; a partitioned passage located in the center of the coil torus and intended to pass through said electrical conduction paths; an insulating support for said electrical conduction paths; and a support for externally disposing said disjunction control mechanism.
  • the block further comprises at least one electronic card which can be mounted externally on said chassis in order to control the operation of said disjunction control mechanism in response to an electrical signal produced by the coil toroid.
  • said upper half-housing comprises a window located above said electronic card included inside and in that a connection cover is provided which forms a cover and which supports on its face directed downwards connection contacts, where it follows that, by fixing the connection cover on an upper face of the upper half-housing, the connection cover hides the window and, simultaneously, the connection cover connection contacts automatically establish the electrical connections between the electronic card and the other active parts contained in the housing and, on the other hand, when the connection cover is removed, the electronic card is completely disconnected, thus making it possible to carry out a dielectric test of the differential protection block without risk of damaging the electronic card.
  • FIG. 1 illustrates the operating principle of a differential protection block in the present invention.
  • the differential protection block is designed for four poles.
  • the parts included in the block are in number corresponding to this number of poles.
  • the differential protection block has four current channels 1, 2, 3, 4 through which the electric currents of the four poles pass, during normal operation of the device.
  • Each current path can be constituted by a metallic structure, for example made of copper, which comprises at each end an input terminal 5 and an output terminal 6 and in its central part an electrical conduction part 7.
  • a magnetic toroid 8 is arranged so as to simultaneously surround the four pieces of electrical conduction 7.
  • the electric circuit presents an anomaly which consists in that a part of the electric current of at least one of the poles is derived so as to pass for example to the ground, the sum of the electric currents which circulate simultaneously through the four parts of electrical conduction 7 is no longer equal to zero.
  • a coil 9 wound around the magnetic core 8 then shows at its connection wires 10, 11 a potential difference or an electric current when the sum of the electric currents which crosses the four electrical conduction pieces 7 is not equal to zero.
  • connection wires 10 and 11 of the coil 9 are connected to an electronic card 12 which is intended to detect the appearance of a certain electric voltage or a certain electric current at the terminals of the coil 9 so as to send an electrical signal intended to control a tripping of a mechanism 13 designed so as to cause the tripping of the multipole circuit breaker D (FIG. 2) connected or coupled to the differential protection block.
  • differential protection block is well known in the prior art and it is generally in the form of an insulating housing which encloses all the parts constituting the device.
  • Figure 3 the general external shapes of the trigger mechanism 13 mentioned above, the trigger mechanism 13 being part of the parts included in the housing 14 of the differential protection block.
  • FIG. 4 represents, in exploded perspective, the essential elements which constitute the differential protection block.
  • This differential protection block is generally constituted by a functional sub-assembly 16 which includes a certain number of parts which we will describe below but which have the essential characteristic of being able to be assembled so as to form a single functional unit, c that is to say a single assembly capable of functioning.
  • the functional sub-assembly 16 is intended to be enclosed in the housing 14, which is constituted by a lower half-housing 14A and an upper half-housing 14B which are made of insulating plastic material and which are intended to come to couple so to constitute the housing 14 inside which is enclosed the functional sub-assembly 16.
  • the housing 14 may, when its two parts are assembled, have a generally external shape that is substantially parallelepiped.
  • the differential protection block further comprises a connection cover 18 whose structure and function will be described later.
  • the functional sub-assembly 16 is constituted by a frame 20 in and around which the connection assembly 22, the coil toroid 30, the electronic card 32 and the trigger mechanism 34 are fixed respectively. More precisely, the coil torus 30 is arranged inside the chassis 20 and the other elements 22, 32 and 34 are mounted outside the chassis 20. It is understood that an essential difference compared to the differential protection block of the prior art lies in the fact that, according to the invention, the differential protection block is constituted by a functional sub-assembly which, as its name suggests, comprises all the elements essential for operation, and a housing 14 which encloses the functional sub-assembly 16 .
  • differential protection blocks known to date, the various functional elements are fixed and housed inside a housing, this housing being produced for example in two parts so as to constitute a cavity internal intended to enclose all the functional elements. It follows from this that it is necessary to close the housing so that the functional elements contained therein can function properly. Consequently, in the differential protection blocks of the prior art, it is not possible to test the operation of the device taken as a whole before the case is closed, which is inconvenient because, when the case is closed , the origin of a fault observed in the operation of the differential protection block cannot be detected.
  • the chassis 20 is constituted by two independent chassis parts 20A and 20B which have a certain mirror symmetry with respect to each other and which are intended to come to couple with one another.
  • the two chassis parts 20A and 20B are each made in a single piece of electrically insulating molded plastic.
  • the chassis part 20A is very generally in the form of a vertical wall 36 and the chassis part 20B is also very generally in the form of a vertical wall 38.
  • the two vertical walls 36 and 38 are substantially parallel to each other when the two parts chassis 20A and 20B are coupled.
  • envelope walls 42, 44 (only the walls of the part 20B are visible in the figure) which extend perpendicular to the respective vertical wall 36 or 38.
  • the wall 42 constitutes a substantially cylindrical external envelope and the wall 44 constitutes a substantially cylindrical internal envelope. Consequently, the space separating the external wall 42 and the internal wall 44 is a substantially annular space which constitutes a housing for the coil toroid 30.
  • a similar annular space is provided in the same way on the chassis part 20A although 'it is not visible in Figure 6.
  • the two annular housings form only an annular housing whose overall width is slightly greater than the width of the torus coil 30. It follows from this that to begin to assemble or mount the functional sub-assembly 16, we start by housing the coil core 30 in the annular housing limited by the walls 42 and 44, then we couple the two pieces of chassis 20A and 20B so as to completely enclose the coil toroid 30.
  • the frame 20 then takes the form which is shown in FIG. 7.
  • the part which is at the center of the annular wall 44 is hollowed out and forms a transverse passage. More precisely, this hollowed out part central comprises four partition walls 46 which extend along an axis 48 which is perpendicular to the vertical wall 38.
  • the partition walls 46 share in four passages the cross section of the central recessed portion.
  • the four electrical conduction pieces 26 (FIG. 5) can pass right through respectively the four passages 50 which are separated from each other by the four partition walls 46.
  • similar shapes symmetrical to the shapes elements 42, 44, 46 and 50 are provided on the chassis part 20A (these forms of the part 20A not being visible in FIG. 6).
  • connection assembly 22 is mounted on the chassis 20.
  • each of the four electrical conduction paths (24, 26, 28) on the chassis 20 is carried out as follows.
  • An electrical conduction piece 26 is fixed radially at one end 52 (see FIG. 5) of the input terminal 24, then the assembly constituted by the elements 24, 26 and 52 is mounted on the chassis piece 20A so that the electrical conduction part 26 passes right through one of the housings 50 and the input terminal 24 comes to be positioned against suitable positioning surfaces formed on the outside of the vertical wall 36 of the chassis part 20A.
  • the output terminal 28 and its extension 54 are mounted on the chassis part 20B so that the output terminal 28 is positioned against suitable positioning surfaces formed on the outside of the vertical wall 38 of the part. chassis 20B. Finally, the free end of the electrical conduction piece 26 is mechanically and electrically connected to the extension 54 of the output terminal 28.
  • the electronic card 32 is mounted on the chassis 20.
  • This electronic card 32 can be positioned above the chassis 20 by snapping onto appropriate latching and positioning means 56 (see FIG. 7).
  • the disjunction control mechanism 34 (visible in FIG. 5) is mounted on the chassis 20 which includes suitable positioning and snap-on surfaces 58 (see FIG. 7).
  • the functional sub-assembly 16 comprises all the mechanical, electrical and electronic elements which allow its operation. It follows from this that it is then possible to connect the input terminals 24 and the output terminals 28 respectively to corresponding terminals of the multipole circuit breaker D and to an electrical circuit (not shown) simulating an electrical charge. One can then, in a conventional manner, act on the electric charge so as to carry out a test functional of the functional sub-assembly 16 thus connected to a multipole circuit breaker.
  • the assembly of the differential protection block can then be completed by mounting the lower half-casing 14A and the upper half-casing 14B on the functional sub-assembly 16 (see FIG. 4).
  • the two half-housings 14A and 14B are thus arranged on the functional sub-assembly 16 and are coupled to each other, the two half-housings 14A and 14B form an external envelope which practically completely encloses the sub-assembly functional 16.
  • This assembly can be completed by adding on the upper half-housing 14B a connection cover 18 whose structure and construction will be explained later.
  • a differential protection block according to the present invention was then completely assembled, and this differential protection block, the test of which revealed that it was operating correctly, can then be disconnected from the multipole circuit breaker and from the electrical test circuit to be stored as differential protection block good for marketing.
  • the coil toroid 30 as shown in FIG. 5 constitutes a sub-assembly which in itself has certain characteristics which will now be described.
  • the coil torus 30 has a general external shape of a torus, as can be seen in FIG. 5, to which is added laterally a protruding part 58 which allows the passage of the output wires of the coil of the torus so that these output wires can be connected to the electronic card 32.
  • this sub-assembly forming the coil toroid 30 has a specific structure which is particularly advantageous in the context of its use in the sub functional assembly 16 according to the present invention.

  • the winding wire of the winding 64 is wound around the O-ring assembly constituted by the torus 60 and the two half-shells of insulation 62A and 62B, and the winding action is carried out so that the winding wire is constantly maintained under a certain tension, so that, when the winding is completed, the permanent tension of the winding wire generally constitutes a certain permanent force which keeps the two half-shells of insulation 62A and 62B applied against the toroid 60. It follows from this that the assembly constituted by the torus 60, the two half-insulating shells 62A, 62B and the winding 64 form a one-piece assembly.
  • the carcass 66 may have an annular shape having a section in the general shape of a U, one branch 66A of which extends along the surface of the coil 64 directed towards the center and the other branch of which 66B extends along from the surface of the winding 64 directed outwards.
  • the free ends of the two branches 66A and 66B include protrusions directed towards one another 68A and 68B, these protrusions having surfaces inclined both towards the bottom of the U-shape and towards the outside. It follows from this that when the carcass 66 is in place, as shown in FIG. 8, it encloses, due to its elasticity, the winding 64.
  • the winding 64 is thus substantially applied against the underside of the part of bottom 66C of the U-shaped part 66, against the internal face of the branch 66A, against the internal face of the branch 66B, against the inclined surface directed towards the bottom of the U-shaped part 70A of the protuberance 68A and against the inclined surface directed towards the bottom of the U-shaped part 70B of the protrusion 68B.
  • the coil toroid 30 further comprises a shield 72 which is constituted by a shield half-shell 72A and a shield half-shell 72B.
  • the two shielding half shells 72A, 72B laterally surround each side of the O-ring assembly formed by the parts 60, 62, 64 and 66 so as to form an almost continuous envelope 72 which serves as shielding.
  • FIG. 9 there is an exploded perspective view of the different components which constitute the coil toroid 30 described in relation to FIG. 8.
  • the carcass 66 is in the form of a half-shell which constitutes a recess of substantially toroidal shape or annular being able to envelop or surround the substantially toroidal external contour of the winding 64. More precisely than what has been described in relation to FIG. 8, it can be seen that the carcass 66 further comprises axially directed tabs 66A, 66B which constitute the branches 66A and 66B of the part 66 described above in relation to FIG. 8.
  • the carcass 66 forms with the branches 66A, 66B a single piece of molded plastic.
  • Figure 10 shows in enlarged perspective view the carcass 66 shown in Figure 9.
  • this carcass has branches 66A, 66B facing each other, these pairs of branches 66A, 66B being evenly spaced around the circumference.
  • the carcass 66 further comprises a portion in lateral protuberance 78 which serves to support and guide the connection wires connecting the winding 64 to the outside.
  • the carcass 66 can be made of an insulating plastic material having good mechanical properties of rigidity and elasticity.
  • the carcass 66 can serve both to provide firm support for the winding 64 and to provide a firm connection with the shield 72.
  • the carcass 66 serves as a connecting part between the assembly constituted by the torus 60, the insulation parts 62 and the winding 64 and the assembly constituted by the two shielding half-shells 72A and 72B.
  • This carcass 66 therefore makes it possible to fix the assembly of all these parts which together constitute what has previously been called the coil toroid 30.
  • the coil toroid 30 constitutes a monobloc assembly in which all the parts that compose it are rigidly connected to each other.
  • This one-piece assembly constituting the coil toroid 30 also has the advantage of being able to be dismantled.
  • the two shielding half shells 72A, 72B and the carcass 74 can be easily removed.
  • This particular construction of the coil toroid 30 also has the advantage of ensuring good protection of the coil 64 which constitutes the most fragile part of the assembly.
  • the carcass 74 encloses the winding 64 in a rigid and elastic manner, thereby avoiding any possibility of the appearance of a play at this winding 64, this play being detrimental because it can damage the winding 64 when the assembly is subjected to certain shocks or certain vibrations.

  • the connection cover 18 is intended to be mounted last, that is to say after having already completely assembled the functional sub-assembly 16, after having tested it and deemed good and after having locked up the functional sub-assembly 16 in the housing 14. More specifically, the connection cover 18 is intended to be fixed on the upper half-housing 14B when the two half-housings 14A and 14B are already assembled.
