Definitions

  • the present invention relates to the general technical field of protective devices for installations and electrical equipment against transient electrical surges.
  • Protection devices for electrical installations are commonly used to protect electrical or electronic devices against overvoltages that can be generated for example by discharges due to lightning.
  • These devices generally comprise an active part formed by one or more protection components, such as for example a varistor or a spark gap.
  • protection components such as for example a varistor or a spark gap.
  • Varistors are commonly used components to protect electrical installations or equipment against transient overvoltages. When the varistors are exposed to voltages above a predetermined threshold value, they are likely to discharge high currents and absorb and dissipate the energy associated with the overvoltage while discharging the lightning current to the ground.
  • thermal disconnection means are intended to isolate the varistor of the electrical installation to be protected in case of overheating of the protective component in order to limit the risk of fire.
  • the thermal disconnection means can thus be formed by a disconnection blade, welded to one of the electrodes of the varistor, and subjected to mechanical stress tending to separate it from the corresponding electrode.
  • the disconnection blade deviates from the electrode, thereby isolating the varistor from the installation to be protected.
  • an overvoltage protection device comprising a varistor and a disconnecting device which includes a rivet held by a solder to a varistor electrode.
  • the rivet is resiliently biased by a spring such that when the solder melts, the rivet is moved away from the electrode. This results in the disconnection of the varistor.
  • the rivet is guided in an insulating part inside which is confined the space appearing between the rivet and the electrode.
  • This phenomenon has the effect of significantly limiting the resistance of the protective device to overvoltages of high amplitude.
  • the size of the complementary cut-off device must preferably be adapted to the capacity of the varistor, which generates technical constraints and increases the costs of implementing the overall protection equipment.
  • the complementary cut-off device generally ensures the simultaneous and indiscriminate isolation of all the protective components of the device, while it is desirable instead to isolate only the varistors with excessive heating and to maintain the others. protection components in use.
  • the objects assigned to the invention therefore aim to remedy the various drawbacks enumerated above and to propose a new device for protecting electrical installations against overvoltages whose resistance to overvoltages is improved.
  • Another object of the invention is to propose a new device for protecting electrical installations against overvoltages which makes it possible to guarantee the individual disconnection of each protection component of the device.
  • Another object of the invention is to propose a new device for protecting electrical installations against overvoltages which is of simple and reliable design.
  • Another object of the invention is to provide a new device for protecting electrical installations against overvoltages requiring only a limited number of mechanical parts in motion to obtain the connection and disconnection functions.
  • Another object of the invention is to propose a new device for protecting electrical installations against overvoltages which makes it possible to indicate in a reliable and instantaneous manner that a protection component of the device is disconnected.
  • the overvoltage protection device according to the invention is intended to be connected bypass on the equipment or electrical installation to be protected.
  • electrical installation refers to all types of devices or networks susceptible to voltage disturbances, including transient overvoltages due to lightning.
  • the overvoltage protection device according to the invention is advantageously intended to be disposed between a phase of the installation to be protected and the earth.
  • the device instead of being connected bypass between a phase and the earth, is connected between the neutral and the earth, between the phase and the neutral or between two phases (case of differential protection).
  • the protection device comprises at least one protection component 10 forming the active part of the surge arrester, intended to protect the electrical installation.
  • each protection component 10 of the device is formed by a varistor, it being understood that the use of a varistor is only indicated by way of example and in no way constitutes a limitation of the invention.
  • the protection device comprises at least one varistor 10, in particular one or more varistors 10, each varistor 10 being provided with connection means 20 to the electrical installation.
  • the varistor 10 is preferably mounted within a housing 60 likely to be in the form of a cartridge adapted to be electrically connected to a fixed base (not shown) using a first and a second connection pads 22, 23.
  • one of the poles of the varistor 10 is connected directly to the first connection pad 22, the other pole of the varistor 10 being connected to the connection means 20, which are preferably formed by an electrode 21, for example in the form of a metal blade.
  • the electrode 21 projects, for example at 90 °, from one of the substantially flat faces 10A of the varistor 10.
  • the device also comprises a disconnection means 30 associated with the varistor 10, and adapted to disconnect the latter from the electrical installation.
  • the disconnecting means 30 is specifically adapted to ensure the disconnection of the varistor at the connection means 20, and is for this purpose capable of moving from a closed position, illustrated for example on the figure 3a , to an open position illustrated on the figure 3b , thus creating an interstitial space 11 between the disconnection means 30 and the connection means 20.
  • the disconnection means 30 is formed by a disconnection blade 31 which, in the closed position, is stress-welded on the connection means 20, precisely on the electrode 21, preferably with the aid of FIG. a hot melt weld (not shown).
  • a hot melt weld (not shown).
  • One of the ends 31A of the disconnection blade 31 then comes into electrical contact with the electrode 21 via the solder, the other end 31B being in permanent electrical contact with the second connection pad 23.
  • the disconnection blade 31 is then elastically constrained between its closed position, in which it comes into contact with the electrode 21 through the thermal weld and its open position in which the disconnection blade 31 is no longer in contact with the corresponding electrode 21.
  • the device comprises arc cutting means 40 intended to prevent the formation of arcing between the disconnection means 30 and the connection means 20 when the disconnection means 30 is in the open position.
  • arc cutting means 40 intended to prevent the formation of arcing between the disconnection means 30 and the connection means 20 when the disconnection means 30 is in the open position.
  • the arc cutting means 40 are formed by an insulating shutter 41 at least a portion of which is able to move within the interstitial space 11.
  • the insulating shutter 41 thus comprises a central portion 42 intended to be interposed between the disconnection means 30 and the connection means 20, and the lateral portions 43, shaped so as to prevent the bypassing of the arc cutting means 40 by the 'electric arc.
  • the lateral portions 43 are shaped so as to generate an increase in the distance to be traveled by the electric arc to electrically connect the electrode 21 and the disconnection blade 31.
  • Such a device therefore makes it possible to increase the isolation distance between the disconnection means 30 and the corresponding connection means 20, thus improving the resistance of the protection device to overvoltages.
  • the insulating shutter 41 was only provided with a central portion 42, it could occur bypassing this central portion 42 by the electric arc, which would limit the effect of the insulating flap 41.
  • the arc cutting means 40 and the disconnection means 30 are mounted relatively such that when opening the disconnection means 30, the latter releases the arc cutting means 40, thus allowing the displacement of these.

  • the disconnection blade 31 is advantageously mounted in stress in such a way that during its opening, it deviates sufficiently from the electrode 21 to no longer constitute an obstacle against the displacement of the insulating flap 41.
  • the force responsible for moving the insulating flap 41 may be of any kind, but will preferably be an elastic restoring force.
  • the arc cutting means 40 advantageously comprise a resilient means 70, of the spring type, mounted so as to exert an elastic return force on the insulating flap 41, said restoring force being exerted in a direction substantially parallel to the axis of compression of the elastic means 70.

  • the device comprises means 50 for indicating the state of the varistor 10, said indication means 50 being actuated by the arc cutting means 40.
  • the opening of the disconnection means 30 the release and the displacement of the arc cutting means 40 will trigger a change of state of the indication means 50 which will then take a configuration of a nature to inform third parties that a varistor is disconnected.
  • the indication means 50 can obviously be visual indication means, or auditory. According to a preferred variant illustrated on the Figures 3a and 3b , the indication means 50 are formed by a display member 51, preferably mounted on the means of arc cutting 40 and capable of moving with them facing a window 61 formed in the housing 60 of the device.

  • the side portions 43 extend on either side of the central portion 42 so as to prevent the bypass of the latter by the electric arc.
  • the structure and the shape of the insulating shutter 41 thus make it possible to increase the distance that the electric arc must travel to electrically connect the disconnection blade 31 to the electrode 21, which amounts to increasing the isolation distance between the means disconnection device 30 and the connection means 20.
  • the isolation distance is defined as the distance that the electric arc must travel in the insulating medium, for example air, to electrically connect the connection means 20, in particular the electrode 21 by means of disconnection 30.
