Definitions

  • the invention relates to a hybrid type switch device for high or medium voltage.
  • the hybrid qualifier applies to the split that is mixed type by cooperating two different cutoff techniques.
  • Hybrid includes a switch device which comprises a vacuum switch enclosing a first pair of arcing contacts and which also comprises a gas switch comprising a second pair of arcing contacts.
  • a device of this type is known from the patent US 3038980 . It comprises a casing filled with a dielectric gas and having a longitudinal axis, inside which are disposed the two electrically connected switches in series and outside which is arranged the control mechanism of the device.
  • the mechanism for actuating the contacts of the two switches is relatively simple, in the sense that one of the two contacts of the gas interrupter is integral with a movable contact which is adjacent to it in the vacuum interrupter.
  • the other contact of the gas switch is secured to an operating rod connected to the control mechanism of the device.
  • a spring mechanism associated with a stop has the effect of keeping the contacts of the gas interrupter pressed against each other during a first part of their stroke when the device is opened, until the contacts of the vacuum interrupter are separated by a determined distance.
  • the purpose of such a sequence for the separation of the contacts of the two pairs is to be able to delay the separation of the contacts of the second pair (gas switch) compared to those of the first pair (vacuum switch).
  • the hybrid high-voltage switching device associates a gas switch provided for a standardized high voltage higher than 72.5 kV with a vacuum switch provided for a standardized average voltage of less than 52.5 kV. kV.
  • the vacuum interrupter withstands all the transient recovery voltage at the terminals of the breaking device during the separation of his contacts.
  • the vacuum switch is only intended to support a recovery voltage that remains within the limits of the medium voltage.
  • This operation involves a relatively long arc duration that a vacuum interrupter is not designed to support.
  • the general structure of the device described in this US Patent 3038980 does not allow to modify the sequence for the separation of the contacts. In particular, it is not possible with such a device to obtain a simultaneous or delayed separation of the contacts of the vacuum interrupter with respect to the separation of the contacts of the gas interrupter.
  • This device has certain disadvantages from a mechanical point of view. Firstly, it is necessary to exert sufficient force on the movable contact of the vacuum interrupter as long as the passage of the current is allowed, so as to have a mutual pressure between the contact surfaces of the contacts of this switch that is greater than a given value to resist the electrodynamic forces during the passage of the current.
  • the steering wheel of the device must therefore be provided with an elastic return system that allows to exert this force required on the movable contact of the vacuum switch.
  • the transmission of the movement of the operating rod of the gas switch to the vacuum switch is by a connecting rod whose axis is oblique with respect to the axis of translation of the moving contact of this vacuum switch. This results in significant transverse stresses on the vacuum interrupter, which can limit its mechanical endurance.
  • the invention aims to remedy the disadvantages or limitations of the prior art, by proposing a hybrid breaking device for high or medium voltage relatively compact and enduring while operating with a single body of maneuvering, that is to say with a control mechanism connected to a single operating rod, makes it possible to adjust the sequence of separation of the contacts of the switches.
  • the displacement means are arranged so that the separations of the contacts of the respectively vacuum and gas switches occur simultaneously. or slightly shifted in time. This makes it possible to distribute adequately between the vacuum interrupter and the gas switch the transient recovery voltage that appears between the contacts of each switch as soon as they are separated.
  • the displacement means are preferably arranged so that the separation of the contacts of the the vacuum interrupter is substantially delayed with respect to the separation of the arcing contacts of the gas interrupter, so that the current flow through zero is caused by the gas switch before the empty does not cut the current.
  • the contacts of the gas interrupter are fitted into one another in the closed position, with a covering distance which is less than or equal to the dead run that can travel through the first part of the return means along the connecting means.
  • the high-voltage hybrid breaking device 5 shown is generally symmetrical about an axis A. It comprises a vacuum interrupter 10 enclosing a first pair of arcing contacts 1 and 2. A first contact 1 is fixed and is permanently connected to an end crossing 7 of the device 5. A second contact 2 is movable in the axial direction A.
  • the device also comprises a gas switch 11 electrically connected in series with the vacuum switch. This gas switch comprises a second pair of arcing contacts consisting of a third and a fourth contact 3 and 4.
  • the third contact 3 is fixed in the envelope 12 by means of holding means shown in FIGS. figures 8 and 9 .
  • the fourth contact 4 is movable in the axial direction A and integral with an actuating rod 6 connected to the control mechanism 8 of the device 5.
  • the two switches 10 and 11 are arranged in a common envelope 12 filled with a dielectric gas .
  • the movable contact 4 is introduced into the fixed contact 3 over a certain overlap distance when the cut-off device is closed.
  • the separation of the third and fourth contacts takes place at a time when the actuating rod 6 has traveled a determined distance of said implementation.
  • speed which is to say that the recovery distance corresponds to the speed setting distance traveled by the rod 6.
  • This speed is applied to the movable contact 4 of the gas switch and allows the contact 4 to be separated fixed contact 3 with a relatively high speed from the beginning of the separation. A few milliseconds after said separation, this speed can reach a sufficient value favoring the extinction of the electric arc created between the contacts of the switch. It is particularly useful for cutting so-called capacitive currents without electric arc striking.
  • the contact 2 is integral in translation with a movable connection means 13 which electrically connects it permanently to the fixed contact 3.
  • the fact of arranging the third contact so that it remains fixed in the cutoff device allows the separation of the contacts 3 and 4 in the gas switch does not depend on the mechanical operation of the assembly bearing the second movable contact of the vacuum switch.
  • Returning means 15 are separable into two parts 16 and 17. These two parts bear against each other in the axial direction A by means of coupling means 22 provided at their two ends facing each other. .
