Definitions

  • This patent concerns protected and non-protected current sockets provided with fuses or protection devices and in particular concerns interlocked sockets.
  • medium and high voltage electricity is supplied, typically 220 or 380 Volts, distributed by means of industrial sockets.
  • This switch can be operated at any time, with the plug inserted.
  • the fuses of the interlocked sockets or the fuse carrier blocks are contained in housings usually accessible from the outside by opening the cover of the housing. It is usually provided with a transparent window so that the indicator showing the condition of the fuse can be checked without having to remove it from its housing.
  • the interlocked socket fuse housing covers can only be opened when permitted by the position of the switch.
  • the aim of the new interlocked socket is to prevent reset of the socket switch by non-authorised personnel.
  • a further aim of the new interlocked socket is to permit disabling of the socket, i.e. opening of the switch, at any time and by any person but not resetting unless the person is in possession of the key.
  • the new socket maintains the standard safety characteristics such as: prevention of opening of the fuse or fuse block cover as long as the socket switch is enabled and the socket is powered, preventing reset of the socket if the fuse or fuse carrier cover is not correctly and completely closed.
  • This switch control lever prevents opening of the fuse cover when it is in the enabled position and permits opening of said cover when in the disabled position.
  • a further mechanism prevents reset of the switch if the fuse or fuse carrier cover is not correctly and completely closed.
  • FIG 1 illustrates various separate parts of the interlocked socket.
  • the outer shell (G) of this interlocked socket comprises at the top a seat (G1) for housing and rotation of a control lever (L) and an aperture (G2) for access to the fuses or fuse carriers.
  • the control lever (L), positioned in the upper part of said shell (G), is designed to control the electromechanical switch powering the socket contacts.
  • Said control lever (L) has a roughly coaxial hole (L1) designed to house the safety and reset key (C).
  • This lever (L) is also coupled, via a pin (P) provided with radial protrusions (P1) and radial hole (P2), to a ring element (A) having spiral grooves or protrusions (A1) on its outer surface.
  • Said ring element (A) is in its turn coupled to the slide (S) locking the plug and supporting the contacts (X) of the switch, and in particular to one of its holes (S1) provided with spiral protrusions or grooves, thus causing, by rotation of said ring element (A), vertical movement of the slide (S).
  • control lever (L) rotates idle around said pin (P); the coupling between control lever (L) and pin (P), and therefore also with the ring element (A), is by insertion of the safety key (C) into the lever (L) until the end of said key (C) locates in the radial hole (P2) of the pin (P).
  • control lever (L) it is possible for said control lever (L) to be provided with protrusions, or other comparable mechanism, designed to permit the rotation of lever (L) with the pin (P) only in the disable direction.
  • a closing cover (T) is hinged on the shell (G) of the socket, designed to protect the fuses or fuse carrier and to almost completely cover the control lever (L).
  • This cover (T) is provided with fastening screw (Tv) for closing it on the shell (G).
  • Said cover (T) is provided with an aperture (T1) to permit sliding of the end of the control lever (L) on the cover (T) when the latter is closed on the shell (G).
  • said aperture (T1) of the cover (T) allows the end of the control lever (L), opposite the pin (P), to be outside the cover (T) and features a recess or widening (T1a) corresponding to the disabled position of the control lever (L).
  • control lever (L) when the control lever (L) is in the enabled position it rests on or overhangs the lower edge of the aperture (T1) of the cover (T) physically preventing it from being raised, whereas when the control lever (L) is in the disabled position, its end opposite the pin (P) corresponds to the recess or widening (T1a) of the aperture (T1), allowing the cover (T) to be raised.
  • the inner part of the cover (T) features a wall (T2) generally horizontal with hole (T2a), as can be seen in figure 2.
  • the shell features an aperture (G3) into which said wall (T2) of the cover (T) locates and penetrates.
  • An elastic element pushes said stop element (R) towards the outside of the socket via said aperture (G3) of the shell (G).
  • the slide (S) locking the plug features a protrusion (S2) parallel to the vertical movement direction.
  • Said protrusion is positioned on the slide (S) so that it crosses the above-mentioned stop element (R) at right angles.
  • the wall (T2) of the cover (T), the stop element (R) and the protrusion (S2) of the slide (S) jointly prevent enabling of the socket if the cover (T) closing the fuses or fuse carrier is not completely and correctly closed:
  • the socket can be disabled by anyone, even without control key (C). In this way anyone can intervene to interrupt the power supply to the socket in an emergency, for example in the event of problems, dangers etc.
  • the socket can be enabled only by authorised persons, in possession of the safety key (C). Without said key (C) rotation of the control lever (L) does not rotate the pin (P), which in its turn does not rotate the ring element (A), which in its turn does not move the slide (S) without closing the contacts (X) of the switch.
  • the socket To disconnect the plug, to raise the cover (T) and to access the fuses or fuse carrier, the socket must be disabled, i.e. the control lever must be rotated (L). Said rotation to disable the control lever (L) moves the slide (S), freeing the plug, and sets the lever (L) to a position that permits raising of the cover (T).
  • the cover (T) must be closed correctly and completely and the safety key must also be used (C).
  • the control lever (L) does not move anything if the safety key (C) is not inserted inside it.
  • the key (C) correctly inserted but with the cover not completely and correctly closed it is not possible to move the slide (S) and therefore enable the socket.
