Definitions

  • the invention relates to a frame for holding a vacuum bulb from power switch module, comprising a first upright and a second identical upright made of electrically insulating material arranged symmetrically about a main axis of the vacuum interrupter.
  • a power switch module provision is made for have several sockets side by side to hold several bulbs at normally identical vacuum, each vacuum interrupter used to interrupt a phase of an electricity transmission line.
  • each vacuum interrupter used to interrupt a phase of an electricity transmission line.
  • the differences in electrical potential between empty bulbs arranged side by side side by side generate significant electrodynamic forces which tend to pushing the vacuum ampoules apart from each other, these efforts being all the more important that the distance between two vacuum interrupters is small. It is therefore essential that the chassis structure receiving the bulb vacuum is very rigid to resist electrodynamic forces and that the vacuum interrupter is not offset axially between the two uprights of the chassis under the constraint of these efforts.
  • the aim of the invention is to propose a new chassis construction which is modular for a low cost, that is to say which accepts several vacuum bulbs from a range of vacuum bulbs for a low cost of realization, and which is able to withstand electrodynamic forces high intensity between phases to allow an arrangement of several vacuum bulb frame in a power switch module with a small footprint.
  • the invention relates to a frame for holding a bulb with no load of power switch module, comprising a first upright and a second identical upright of electrically insulating material arranged symmetrically with respect to a main axis of the bulb to empty, characterized in that a plate of electrically insulating material is rigidly linked to the uprights by embedding and clipping, this plate used to maintain and center the vacuum interrupter between said amounts.
  • the adaptation of the chassis to several types of vacuum ampoules simply consists of the realization of a plate of centering for each type of vacuum interrupter.
  • the holding functions and for centering the vacuum interrupter according to the invention are therefore not carried out by a metal foundry piece.
  • This centering plate being of preferably made by molding and / or thermoforming a material plastic and / or composite, it has a very low cost price. Else apart, this plate which is made of an electrically insulating material and which is fixed to the chassis uprights by embedding and clipping allows, with the metallic electrical connection parts fixed by screws to the uprights, to reinforce the chassis structure to take over a large part of the electrodynamic forces which are applied to the vacuum interrupter in a power switch module. This arrangement contributes to obtaining a very compact arrangement of the frames in a module power switch.
  • FIG. 1 is a perspective view of a chassis according to the invention in which is fitted with a vacuum interrupter.
  • FIG. 2 is a perspective view of the chassis according to the invention without the vacuum interrupter.
  • Figure 3 is a perspective view of the centering plate of the chassis according to the invention.
  • Figure 4 is a perspective view of a frame amount according the invention.
  • FIG. 5 is a sectional view of the chassis according to the invention in which is installed a vacuum interrupter.
  • Figure 6 is an overview of three chassis according to the invention associated within the same power switch module.
  • FIG. 1 we see a frame comprising two identical uprights 1 and 2 of electrically insulating material arranged vertically, one first metal part 3A which is rigidly linked to the upper part of the two uprights, a second metal part 3B which is rigidly linked at the bottom of the two uprights.
  • the two metal parts 3A and 3B are used for the electrical connection of the terminals of the vacuum interrupter 4 which is placed between the two uprights 1 and 2.
  • the metal part 3A also has function of keeping the vacuum interrupter 4 in suspension between the two amounts.
  • a plate 5 made of material electrically insulating is embedded and clipped between the two uprights 1 and 2. This plate 5 is used to hold and center the vacuum interrupter between the two uprights 1 and 2 which are removably attached to a plate by screws 6, this plate constituting a wall of a switch module power.
  • the vacuum interrupter has a main longitudinal axis 7 and the two identical uprights 1 and 2 are arranged symmetrically by relative to axis 7.
  • the vacuum interrupter 4 arranged vertically between the two uprights 1 and 2 vertical, is maintained and is centered between the two uprights by the centering plate 5.
  • FIGS 2, 3, and 4 provide a better understanding of the nature of the mechanical connection between the centering plate 5 and the two uprights 1 and 2 of the chassis.
  • the centering plate 5 has a shape approximately rectangular and has a light 8 at each of its two ends as well as a clip tab 9 arranged at near a light 8. Each tab 9 has a lug 10.
  • the centering plate 5 also has a cylindrical bore 11 in position central between the two lights 8 and the two tabs 9.
  • the plate centering 5 may have reinforcing ribs around the slots 8 and bore 11.
  • each amount such as 1 or 2 comprises in its central part a positioning pad 12 which is intended to come engage in a slot 8 of the centering plate 5 and a slot 13 disposed above the stud 12 and in which engages the lug 10 of a tab 9 of the centering plate 5.
  • each upright 1 or 2 has a recess 14 arranged under the stud 12 and through which can be inserted the centering plate 5.
  • the chassis is able to withstand bending stresses relative to axis 7 or torsional stresses relative to this axis, corresponding to interphase forces and to loop forces which are applied by the bulb to the centering plate 5 in the plane of this plate.
  • this strengthening of the rigidity of the chassis is achieved without metallic material so that it does not increase efforts between phase electrodynamics that the chassis can undergo.
  • the cylindrical bore 11 of the centering plate 5 is intended to receive a complementary cylindrical part of the vacuum interrupter, by example the lower part 18 (visible in FIG. 5) thereof in which slides the operating rod 19 of the movable contact. Since the vacuum interrupter is suspended from the metal part 3A and is centered along the vertical axis 7 between the two uprights by the piece of centering 5, a large part of the electrodynamic forces which are applied to the bulb are taken up by the centering plate 5 then by the amounts so that the rigidity of the whole chassis is found significantly improved. From the point of view of the adaptability of the chassis to several types of vacuum ampoules, it is important to note that adaptation of plate 5 to the type of vacuum interrupter that one wishes to mount on the chassis according to the invention will generally be sufficient. So if by example the centering diameter of the bulb is different, it will suffice make a centering plate with a bore 11 in diameter corresponding.
  • centering plate 5 can be inserted between the two uprights 1 and 2 through one or other of the recesses 14, it is preferable to provide for the clipping of the tongues 9 into slots 13 arranged on the outside face of the uprights.
  • Figure 5 illustrates the positioning of these tabs 9 on the outside of the uprights 1 and 2.
  • the centering plate 5 is disposed between the parts 3A and 3B electrical connection along axis 7.
  • FIG. 6 illustrates a power switch module with three chassis arranged side by side and in each of which is installed a vacuum bulb.
  • the longitudinal axes of each bulb are indicated by 7,7 ', 7 "and the respective amounts of the chassis are indicated respectively by 1.2; 1 ', 2'; 1 ", 2".
  • the uprights of one chassis and the uprights of another adjacent chassis are face two to two. More specifically, the uprights 1,1 ', 1 "are arranged in alignment parallel to the alignment formed by the uprights 2,2 ′, 2 ", the two rows of uprights 1,1 ', 1 "and 2,2', 2” being arranged on the side and the alignment of the axes 7,7 ', 7 ".
  • the fundamental interest of this layout is the compactness obtained for the switch module power.
  • the two uprights and the centering plate of a chassis can be made inexpensively by molding and / or thermoforming a material plastic and / or composite.
