Definitions

  • the invention relates generally to the field of electrical protection.
  • the invention relates to a lightning protection device for a three-phase electrical network comprising first, second, and third phase conductors, a neutral conductor and a ground conductor, this device comprising three components of the first type arranged between the three respective phase conductors and the neutral conductor, and at least one second type component disposed between the neutral conductor and the earth conductor.
  • the present invention aims to provide a very advantageous alternative to this solution.
  • the three modules which are consumable products, can be identical to each other and can be used interchangeably in a three-phase network and in a single-phase network, which simplifies the management of their stock and streamlines production.
  • the impedances of the fifth and seventh links are substantially equal to each other, this expression applying to impedances having between them only a maximum relative difference of 5%.
  • Each component of the first type preferably has a variable impedance and comprises for example a varistor.
  • Each component of the second type advantageously has a discontinuously decreasing impedance and comprises for example a spark gap.
  • the base preferably comprises three multicore jacks in each of which a module is plugged removably.
  • the base comprises a printed circuit board supporting said connections and tracks constituting said electrical connections.
  • the invention relates to a surge protection device for a three-phase electrical network.
  • Such a network typically comprises figure 1 ) three phase conductors L1, L2, L3, a neutral conductor N and a ground conductor T.
  • a surge protection device for such a network comprises, in known manner, three components of the first type C11, C12, and C13, arranged between the three respective phase conductors L1, L2, and L3 and the neutral conductor N, and a component of second type C21 disposed between the neutral conductor N and the earth conductor T.
  • the first type of components, C11, C12, and C13 typically have a variable and decreasing impedance depending on the current flowing through them, and generally consist of a varistor.
  • the components of the second type, C21, C22, and C23 typically have an impedance that decreases discontinuously as a function of the voltage applied thereto, and are generally each constituted by a spark gap.
  • the device of the invention comprises a base E and three interchangeable modules M1, M2, and M3, these modules being preferably identical to each other.
  • Each of these modules M1, M2, and M3 comprises a component of the first type, respectively denoted C11, C12, and C13, and a component of the second type C21, C22, and C23, the components of the first and second types of each module being connected to each other by a common terminal respectively denoted BN1, BN2, and BN3.
  • each module M1, M2, and M3 has a phase terminal, respectively denoted BL1, BL2, and BL3, and constituted by the free terminal, that is to say non-common , of the first type component C11, C12, and C13 of this module.
  • each module M1, M2, and M3 has a ground terminal, respectively denoted BT1, BT2, and BT3, and constituted by the free terminal, that is to say non-common, of the component of the second type C21, C22, and C23 of this module.
  • the base E is designed to physically support each of the modules M1, M2, and M3 and has five connections K1, K2, K3, K4, and K5.
  • the first three connections K1, K2, and K3 are designed to connect respectively to the three phase conductors L1, L2, and L3.
  • the fourth connection K4 is adapted to connect to the neutral conductor N
  • the fifth connection K5 is adapted to connect to the earth conductor T.
  • the base E is preferably essentially constituted by a printed circuit board supporting the connections K1 to K5, as well as three multicore outlets PM1, PM2, and PM3, in each of which is removably connected a corresponding module M1, M2, or M3.
  • the electrical connections P1 to P9 can then be constituted by tracks carried by this printed circuit board.
  • the electrical connections P1 to P9 may also be constituted by insulated conductor wires, for example arranged on the rear face of this printed circuit board.
