Definitions

  • the present invention relates to an overvoltage protection device.
  • This type of protection device is effective but scarcely versatile.
  • Such devices are in fact associated in advance with a single socket, and the entire socket has to be replaced when they burn out.
  • the aim of the present invention is to solve or substantially reduce the problems of conventional overvoltage protection devices.
  • an important object of the present invention is to provide an overvoltage protection device which is removable, i.e., associable with different power sockets.
  • Another object of the present invention is to provide a device which has a low cost.
  • Another object of the present invention is to provide an overvoltage protection device by using conventional elements and equipment.
  • an overvoltage protection device characterized in that it comprises a plug which can be inserted in a power socket and whose three terminals, two for connection to the phases and one for connection to the ground, are associated with an electric circuit, said circuit being contained in a box-like body which is rigidly coupled to a base for supporting said terminals, and comprising a first and a second varistor which are respectively connected between each terminal for connection to the phases and the ground connection terminal, said two phase connection terminals being further connected so as to have two parallel branches, the first one of said branches being provided with a varistor, the second branch being provided with a dissipative resistor and a lamp which are connected in series.
  • a device according to the invention is generally designated by the reference numeral 10.
  • This device 10 comprises a plug 11 which is constituted by two terminals 12a and 12b for connection to the phases and a terminal 13 for connection to the ground which is rigidly coupled to a base 14.
  • the device 10 is further constituted by a box-like body 15 which is also rigidly coupled to the base 14 and contains the elements that constitute the circuit 16 of the device 10.
  • the circuit 16 is shown schematically in Figure 2 and is constituted by two varistors 17a and 17b, each of which is connected between each terminal for connection to the phases 12a and 12b and the ground connection terminal 13.
  • phase connection terminals 12a and 12b are further connected in parallel to two branches 18 and 19.
  • the branch 18 comprises a third varistor 17c.
  • the branch 19 comprises a dissipative resistor 20 which is series-connected to a lamp 21.
  • the electronic circuit 16 is contained, as mentioned, inside the box-like body 15, which has an opening 22 arranged at the lamp 21.
  • the protection device 10 can be applied to all multiple power sockets.
  • Figure 3 illustrates an example of application to a trailing multiple socket 23.
  • the varistors 17a, 17b and 17c are inserted in the circuit 16 so as to withstand a supply voltage whose value can vary up to a maximum which depends on the type of varistor.
  • the power supply circuit is subjected to a voltage peak, due for example to the discharge of lightning, if the value of the peak exceeds the voltage that can be withstood by the varistor, said varistor burns out, shorting the multiple socket and protecting any appliances connected to the other sockets of said multiple socket.
  • the lamp 21 lights up and is visible from outside through the opening 22 of the body 15.
  • the device is also very versatile, since it can be removed from one multiple socket and applied to others.
  • the materials employed may be any according to requirements.
