Definitions

  • the invention relates to an electrical circuit-disconnector switch adapted to receive a protection fuse.
  • a switch-disconnector performs the function of switch by allowing to cut and restore the passage of electric current in the circuit on which it is mounted.
  • a switch-disconnector can also isolate a section of power line to allow access to it without danger of inadvertent restoration of the passage of electric current by manipulation of the switch.
  • the function of the disconnector is to prevent any current flow in the switch even in case of overvoltage.
  • switch-disconnector when such a switch-disconnector is provided with a fuse, it protects the electrical circuit against possible short circuit or electrical overload.
  • EP-A-0 584 587 discloses a fuse switch-disconnector adapted to perform these functions properly and which comprises a housing having at its ends two terminals for its connection to two sections of power lines. To fulfill its switch function, this switch-disconnector is equipped with a switching device comprising, in particular, a removable contact plate under the effect of a handle pivoting about an axis. In its middle part, the housing defines a cavity adapted to receive an insert carrying a fuse. This cavity has, in its upper part, an opening through which can be introduced the fuse insert, when the opening is not covered by the handle, as in the case of the figure 3 of EP-A-0 584 587 .
  • the fuse insert When inserted into the cavity in the engaged position, the fuse insert electrically connects the terminals to each other while fulfilling the protection function of the circuit. Conversely, when the fuse insert is removed from the cavity, the switch is open, the electrical contact between the terminals can not be established and the switch-disconnector then performs its function of disconnector.
  • the fuse insert is screwed into the cavity until the support of a movable contact bridge on a contact electrically connected to one of the terminals.
  • a pawl is folded by a torsion spring against the fuse insert, so as to emit a loud noise. the engagement of the fuse insert at the bottom of the cavity.
  • the ratchet prevents folding the handle to close the switching device as long as the contact plate and the contact are disjointed.
  • US-3,474,373 discloses a power line disconnect switch comprising a housing with two terminals and a switch for cutting and restoring current flow.
  • the housing defines an open cavity for receiving a fuse insert.
  • the two lugs for fixing the insert in the cavity do not allow simple or effective locking of the insert in the housing. Indeed, the movement of the insert is not precisely guided and there is no specific means to ensure its maintenance in the contact position.
  • the present invention aims to overcome these disadvantages by providing a switch-disconnector where we can set up the fuse insert in a simple, fast and certain.
  • the invention relates to an electrical line-disconnector comprising a housing having two terminals, able to receive sections of power lines, and a switching device adapted to cut and restore the passage of a current. between the terminals, the housing defining an open cavity and being able to receive a fuse insert, the cavity being defined, near its opening, by a wall integral with the housing and intended to guide the fuse insert towards the cavity, the housing comprising a first contact member, positioned at the bottom of the cavity and electrically connected to one of the terminals, and a second contact member positioned between the opening and the first contact member and electrically connected to the other terminal, characterized in that it comprises means for rapidly locking the fuse insert by screwing the fuse insert limited to a partial revolution angle of less than or equal to 270 °, the fuse insert being able to connect electrically the first and second contact members when in the locked position, and in that the locking means comprise at least one lug integral with the fuse insert and at least one receiving groove of said lug, in that the wall has a generally cylindrical
  • the fuse allows the passage of current when the insert is locked in the housing by a short screw, quarter-turn type or equivalent.
  • the grooves with helical ramps allow precise guidance of the movement of the insert in the cavity and the recessed seat terminating one of these ramps ensures a firm hold of the insert in the cavity, so its locking in the housing.
  • the switch-disconnector illustrated by the figure 1 comprises a housing 1 generally shaped parallelepiped right, whose longitudinal ends along the X axis of an orthogonal coordinate system XYZ respectively accommodate an upstream terminal 2 and a downstream terminal 3.
  • the terms upstream and downstream are chosen by reference to the arbitrary direction of a current likely to pass through the switch-disconnector and symbolized by an arrow I on the Figures 1 to 3 , 5 and 7 .
  • On the figure 1 only one half 1A of the housing 1 is shown in solid lines to better visualize its internal composition. His other half 1B is represented, at the figure 1 , by its trace in phantom, and at the figure 7 in perspective.
  • the terminals 2 and 3 are fixedly mounted relative to the housing 1 and each cooperate with a contact screw 2A or 3A capable of compressing one or two termination (s) of electrical line (s) L 2 and L 3 , shown in phantom, within a housing 2B or 3B.
  • a contact screw 2A or 3A capable of compressing one or two termination (s) of electrical line (s) L 2 and L 3 , shown in phantom, within a housing 2B or 3B.
  • the terminations of sections L 2 and L 3 are respectively brought into contact with an upstream contact strip 4 and a downstream contact strip 5.
  • the housing 1 defines a cavity 10 able to receive an insert 20 having a fuse 21.

  • the switching device comprises in particular a handle 8A pivotally mounted relative to the housing 1 about an axis Y 8 -Y ' 8 parallel to the axis Y.
  • the handle 8A makes it possible to interrupt the passage of the current I acting on a lever 8B represented only at figure 7 which slides down a contact bridge 7 so as to separate it from the downstream lamella 5 and an intermediate lamella 6.
  • Figures 1 to 3 the handle 8A is shown in the open position of the circuit.
  • the arrow symbolizing the current I is therefore represented in dotted lines, because the current I does not pass.

  • the switch-disconnector comprises two grooves 12 and 13 each having a ramp 12A or 13A of helical shape.
  • These helical ramps 12A and 13A each extend over a portion of the wall 11 limited to an angle ⁇ of the order of 95 ° visible on the figure 5 .
  • This angle ⁇ corresponds to a revolution of about a quarter turn, so that it is between 85 ° and 105 °.
  • Each groove 12 or 13 opens into the upper part of the opening 9 via a groove 14 or 15 straight and parallel to the axis Z 11 -Z '11. In the lower part, the groove 13 ends with a seat 18 of rectangular profile.
  • the junction between the helical ramp 13A and the seat 18 is formed by a flat 16 followed by a short end ramp 17 leading to the seat 18 and directed upwards, unlike the helical ramp 13A.

  • Ramps 12A and 13A rely on a dextral helix.
  • the pitch they constitute is therefore oriented to the right. Therefore, to be introduced into the cavity 10 or to be extracted, the insert 20 must be respectively screwed or unscrewed by a quarter turn.

Such a shape does not therefore not an obstacle to the introduction of the insert 20 nor, in particular, to the passage of the cap 22 and the tongue 25.
  • the dimensions of the tongue 25 and the corresponding portion 4A are selected according to the thermal rating of the switch-disconnector, that is to say in order to obtain an area and a section sufficient for the passage of the current without risking deterioration of the parts in contact.
  • the housing 1 comprises a protective rib 10A positioned to cover the upper and inner faces of the portion 4A.
  • a rib 10A is made of electrically insulating material and is integral with the housing 1. It allows to hide the portion 4A to prevent accidental contact with the finger of an operator passing through the opening 9, for the case where the upstream section L 2 of the power line is directly connected to a current generator maintained under tension.
  • the housing 1 has a second protective rib 10C disposed parallel to the rib 10A and below, so as to prevent accidental contact between the portion 4A and the finger folding upward of an operator.

  • the insert 20 To set up the insert 20 with its fuse 21 in the cavity 10, it must be screwed into the housing 1 in a quarter-turn revolution to bring the tongue 25 in contact with the portion 4A. For this, it is first necessary to present, facing the opening 9, the lower part of the fuse 21, then introduce it into the generally cylindrical volume defined by the wall 11. It is then necessary to present the tongue 25 opposite of the corresponding triangular region 19 of the opening 9. The tongue 25 is then in the open or sectioned position symbolized by the letter O to the figure 5 , corresponding to the position illustrated by the figure 2 .

  • the lugs 23 and 24 are then respectively engaged in the input grooves 14 and 15 before approaching the helical ramps 12A and 13A.
  • the operator must then turn the insert 20 to print a helical movement, in the direction of the arrow H to the figure 3 , guided by the grooves 12 and 13. During this movement H, the insert 20 accostes the intermediate contact 6 through the lower pole 21A. The contact 6 thus constitutes the first electrical contact member touched by the insert 20.
  • the pins 23 and 24 s engage the flats 16 by which the movement of the insert 20 becomes a pure revolution, without translation.
  • the flats 16 correspond to the lowest points reached by the pins 23 and 24, where the spring 6A is the most compressed.

  • the fuse 21 transmits this force to the tongue 25 which is kept in contact with the portion 4A by a pressure ensuring a large electrical interface area, thus minimizing the heating of the conductive parts.
  • the spring 6A is not intended to exert the force on the lugs 23 and 24, which, in this case, remain free from mechanical stresses when they occupy their respective end positions within the grooves 13 and 12.
  • the lugs 23 and 24 thus float at the seat 18 and the triangular prismatic volume.
  • the fuse 21 electrically connects the first member 6 to the second member 4.
  • the handle 8A is folded down on the housing 1 thus closing the electrical circuit, the lamella 6 is electrically connected to the downstream lamella 5 via the bridge 7, which allows the passage of the current I through the switch-disconnector.
  • the operator When the operator wishes to isolate the electrical line where the switch-disconnector is mounted, he must first raise the handle 8A cutting the current I so as to access the insert 20. It must then unscrew a quarter- de-turn the insert 20 to extract it from the cavity 10.
  • the upper part of the cap 22 has two gripping zones 22B and 22C symmetrical with respect to the median vertical plane and thanks to which the operator can grasp and manipulate the insert 20. When the latter is removed from the cavity 10, the electrical line L 2 -L 3 on which is mounted the switch-disconnector is effectively isolated, without risk of inadvertent recovery of the current I.

  • the operator visually observes that the contact is established by the fuse 21 when it has aligned the 22D face and 1C mark, without the need to hear a click.
  • the introduction of the insert 20 is therefore particularly fast and intuitive for an operator. This is an essential advantage when the operator has to set up a large number of fuse inserts.
  • the switch-disconnector may comprise a not shown locking device preventing the operator from folding the handle 8A in the closed position when the contact is not established, that is to say when the insert 20 to fuse 21 is not itself in closed position F.
