Definitions

  • the present invention relates to the general field of electrical switchgear and more particularly to systems for operating the break in such devices.
  • the electric switchgear is equipped with a control system connected to the electric breaking poles from which the power cut is controlled.
  • the control system represents the most important safety element of the installation because it ensures the level of performance and reliability of the electrical switchgear as well as the interface between a user and the electrical part of power the device or devices powered by electric current.
  • the control system allows the user to switch the cutoff poles or poles from a closed position (establishment of the electric current), called the "closed position”, to an open position (cut-off of the electric current), called “position “cut-off”, and vice versa, by means of a control handle.
  • the control system comprises a storage mechanism formed mainly of an internal carriage connected to the control handle and an external carriage connected to a control axis of the breaking poles, the internal carriage sliding in the external carriage .
  • a spring is interposed between the two carriages so as to accumulate mechanical energy during movement of the internal carriage by the control handle and to restore this energy to the external carriage at the end of travel of the control handle in order to allow a quick and reliable opening or closing of the cutoff pole or poles.
  • the external carriage of the control system which is connected to the poles by a control shaft, can remain blocked while the control handle has realized. the entire stroke between the closed position and the cut position.
  • the control system is no longer usable in that the welding of one or more poles prevents the control of the opening of all the poles.
  • EP 0 299 291 discloses a storage control system for one or more electric shutdown poles the system comprising: a storage mechanism comprising a movable control handle at least between a closed position and a cutoff position, and vice versa; a first link pivoting about a first point of rotation between a first position and a second position, and vice versa, by actuating the control handle of the accumulation mechanism between the off position and the closed position, and vice versa; a second connecting rod pivoting about an axis of rotation intended to be connected to one or more breaking poles, the second connecting rod being connected to the first connecting rod by a sliding connection so that the displacement of the first link between the first position and the second position, respectively between the second position and the first position, causes the pivoting of the second connecting rod about the axis of rotation between an open position of the cut-off pole (s) and a closing position of the at least one pole of cutoff, respectively between a closed position of the cutoff poles and an open position of the cutoff poles or poles.
  • the object of the present invention is to propose a new design of a control system which makes it possible to force cut-off poles whose contacts are soldered.
  • the triggering control system of the present invention makes it possible to detect a possible blockage (ie welding) of one or more cut-off poles connected to the control system. Indeed, if one or more breaking poles are welded, it is possible to detect it by a resistor in the control handle when it is actuated beyond the cutoff position. In addition, when a force greater than the locking force of the welded breaking poles or poles is applied to the control handle, the contacts of the pole or poles can be released, which allows the control system to return to its position. Normal position of cut.
  • the internal carriage comprises at least one stop adapted to come into contact with the external carriage when the inner carriage is moved by the control handle towards the opening position of the cutoff pole or poles while the external carriage is locked in the closed position of the breaking poles so as to force the movement of the external carriage towards the switch position by means of the control handle.
  • control system of the invention comprises a lockout device comprising a lockout element movable between a neutral position and a lockout position for locking the accumulation control system in the cutoff position and in that said padlocking device further comprises control means for locking the lockout element in the neutral position when the external carriage is locked in the closed position of the breaking poles while the control handle is moved in the breaking position.
  • the system of the invention can be locked in its breaking position, and in a completely secure manner because it can not be locked if the external carriage is locked in the closed position of the breaking poles even if the control handle is moved to the cut position.
  • the control system can not be locked if one or more cutoff poles are soldered in their closed position.
  • control system of the invention comprises at least one rocker pawl movable between a high position when the external carriage is in the closed position of the breaking poles and a low position when said external carriage is in the open position of the breaking poles and in that the padlocking device comprises a locking element movable between a neutral position when the rocker pawl is in the low position and a blocking position when the rocker pawl is in the high position so as to lock the lockout element in the neutral position when the external carriage is locked in the closed position of the cutoff poles while the control handle is moved to the cutoff position.
  • the locking element is thus able to test the position of the rocker pawl and to authorize the locking of the system in the cutoff position only if the pawl is in the low position, position indicating that the external carriage is in the position and therefore no break-off pole has been blocked in the closed position.
  • the locking element is able to block the displacement of the control handle when said locking element is in the locking position. Thus, it further prevents any movement of the control handle.
  • the lockout element comprises a tab having an accessible light when said lockout element is in the lockout position. It is thus possible to lock the system in the cutoff position by placing one or more padlocks in the light, which makes it possible to secure the intervention of one or more operators.
