Definitions

  • the invention relates to the field of the distribution of the electric current under medium and high voltage and, in particular, the switch disconnector devices used in the transmission lines of electrical energy under medium voltage.
  • a first type of disconnector switch operates in a sulfur hexafluoride SF 6 environment where, most often, the functions of interruption or sectioning of the electric current are carried out at the same time by the mechanical separation of movable contacts, one by relative to others, a distance sufficient to ensure sectioning.
  • the cells in which these switches are installed are of small width, for example 375 mm for 24 kV.
  • Another technology is to interrupt the current in the ambient air. Again, the functions of interruption or sectioning of the electric current are performed at the same time by the mechanical separation of the contacts.
  • the cells in which these switches are installed have a large width, for example 600 to 700 mm for 24 kV.
  • Another technique is to cut the electric current in the vacuum, for example by means of a vacuum interrupter placed in series with a disconnector placed on the transmission line of the electric current. This solution is expensive and is not widely used.
  • Another technology is to operate the interruption of the electric current in oil. This is the case of older generation devices.
  • the disconnecting switches operating in the medium voltage SF 6 can interrupt electrical currents of the order of 600 to 800 amperes. Above 800 amps and especially for the value of 1,250 amps, the switches made have costs much higher than other disconnecting switches.
  • the electric power cutoff cells operating in the air are large and generally have lower cutoff performance than those obtained with devices operating in the SF 6 .
  • the object of the present invention is therefore to propose another technology of medium voltage switch disconnectors, avoiding using the sectioning conditions which are those of the technologies listed above, without presenting a high manufacturing cost and having a low impact on the greenhouse effect.
  • a first type of contact among the two types of movable fixed contact (s) is completed, successively and in the determined direction of movement of the movable contact (s) of a first a polyoxymethylene element and a second polytetrafluoroethylene element, so that, during a current cutting operation, the incipient electric arc is first confronted with the first polyoxymethylene element, then the second polytetrafluoroethylene element.
  • the polyoxymethylene is of the homopolymer type.
  • the polytetrafluoroethylene is chosen from the group of PTFE loaded with SiO 2 , PTFE loaded with CaF 2 and PTFE loaded with MoS 2 .
  • an insulating enclosure 14 on the edge of which are diametrically opposed, two fixed contacts 1 and inside which is pivotally mounted about an axis concentrically A to the casing 14, a movable contact 2.
  • This is in the form of a rod whose length is slightly less than the inside diameter of the insulating envelope 14, and whose ends 21 can come into contact simultaneously on the ends 17 of the contacts 1 opening inside. the insulating envelope 14.
  • first arrow 12 The arrival of the electric current is symbolized by a first arrow 12, applied to a first fixed contact 1 and the output is shown schematically by a second arrow 13 out of the other fixed contact 1, diametrically opposite the first.
  • the invention provides to place, around the end 17 of each fixed contact 1, a first polyoxymethylene element, preferably homopolymer, in the form of a washer of polyoxymethylene 11, called POM washer.
  • POM washers 11 are placed at the inner wall of the insulating envelope 14, so that the end 17 of each fixed contact can open into the insulating envelope 14.
  • the assembly is complete on the inner wall of the insulating jacket 14 of two second polytetrafluoroethylene elements in the form of two polytetrafluoroethylene (PTFE) protective strips 15, each of which is in the form of an arcuate strip.
  • PTFE polytetrafluoroethylene
  • a first end substantially touches the POM washer 11, the other end being at a non-negligible distance from the end 21 of the movable contact 1.
  • the two protective strips 15 are diametrically opposed and have a shape that corresponds to the displacement of the ends 21 of the movable contact 2, which is rotatably mounted around the central axis A.
  • a natural PTFE or loaded with SiO 2 or loaded with CaF 2 or charged with MoS will be chosen. 2 .
  • a rotation of one or two tens of degrees of the moving contact 2 about its axis of rotation A makes it possible to pass from a first current-passing position, in which these ends 21 are in contact with a end 17 of a fixed contact 1, at a second current-breaking position, after rotation of the movable contact 2, when the ends 21 of the movable contact 2 are remote from the ends 17 of the two fixed contacts 1.
  • Polyoxymethylene POM is a gas generating material.
  • an electric arc is generated between the ends 17 of the fixed contacts 1 and the ends 21 of the movable contact 2.
  • Each washer of POM 11 surrounding each end 17 of fixed contact 1 the electric arc thus sublimates a portion of the washer POM 11, causing a partial sublimation of the POM washer and thus releasing an electrophilic gas "CH 2 O formaldehyde".
  • CH 2 O formaldehyde an electrophilic gas
  • the gas generated by this chemical transformation is a decomposition gas of POM when it is altered by high temperature.
  • the gas thus generated will interfere with the plasmas of the electric arc, cool it and participate in its extension by its properties.
  • Other materials such as polypropylene, polystyrene, polyethylenes and polymethyl methacrylate etc ... produce "formaldehyde” under the effect of heat.
  • the role of the protection plates 15 makes it possible to continue this phenomenon to achieve the rapid and complete removal of the two electric arcs between the ends 17 of the fixed contacts and the ends 21 of the movable contact.
  • Tests under CO 2 gas showed the notorious efficiency of more than 50% compared to the amperage of the electric current, the presence of POM 11 washers allowing to cut electrical currents of the order of 630 amperes, under 12 kV compared to 400 amperes, at 12 kV, without presence of POM.
  • FIG. 2 shows mainly the PTFE protective strip 15, associated with the POM washer 11, which itself surrounds the end 17 of a fixed contact 1.
  • a fastening lug 18 projecting from the inside of the insulating envelope and which enters a hole 19 of the PTFE protective strip 15.
  • the figure 3 shows the assembly of a disconnector switch, according to the invention, according to the technology described above, applied to three electrical phases, for example three three-phase power lines. It distinguishes mainly the insulating casing 14 on the inner wall of which are three PTFE protective strips 15, each fixed by a tongue 18. Inside these insulating casings half-casings 14, is mounted rotating the axis of rotation A, which carries the movable contacts 2, which is distinguished by an end 17. This rotating shaft A also carries protective elements 19 of the movable contacts 2. It is thus understood that, after a rotation of a ten degrees of rotation shaft A, the ends 17 of the movable contact 2 travel in a circular arc along each a PTFE protective strip 15.
  • the figure 4 shows such a device in the form of an industrial drawing type cut with many details. It will suffice to distinguish the sealed envelope 14 inside which is mounted the rotation shaft A. There are three pairs of fixed contacts 1 protruding inside the cavity of the insulating enclosure 14 by 17. They are each surrounded by a POM washer 11 and are in contact with current arrivals 21. The PTFE protective strips 15 are suggested in finer lines behind the moving contact 2, which are realized here. by a double plate surrounding by its end 21, the end 17 of a movable contact 1.
  • a second embodiment of the invention which can be described as pivoting, is comparable to the first embodiment. It comprises, like it, two fixed contacts 50 and 57, opposite or emitted face to face, but being separated by a determined distance.
  • a POM washer 51 placed around the contact end of a second contact 50 is also used, similarly to the first embodiment, a curved PTFE protective strip 55 is placed adjacent to the POM washer 51.
  • the diameter of this protective strip 55 is equal to the length of a movable contact 52, itself pivotally mounted about an axis of rotation 5A, placed on or in contact with a first fixed contact 57.
  • the contact mobile 52 by pivoting, can separate from the end of the second contact 50, its distal end along the inner wall of the protective strip 55.
  • the figure 6 represents a third embodiment of the invention which will be described as longitudinal while the first may be described as circular or tubular.
  • a fixed contact 31 which has the tubular shape of longitudinal axis B.
  • a movable assembly 40 comprising, inter alia, a movable contact 42 partially surrounded, at least on the side where the fixed contact 31 is located, a POM sleeve 41.
  • a PTFE strip 45 Between the fixed contact 31 and the POM 41 sleeve is a PTFE strip 45 whose inner diameter corresponds to the inside diameter furthermore, it will be noted that the outer diameter of the fixed contact 31 is very slightly less than the inside diameter of the PTFE protective strip 45 and that of the POM sleeve 41.
  • the minimum internal diameter of the mobile contact 42 must be slightly smaller than the external diameter of the fixed contact 31 so that these two elements can be in contact with a sufficient pressure during a translation of the mobile assembly 40 to the fixed contact 31.
  • the mobile assembly 40 can be assembled by means of a casing 43 or holding plate 44.
