Definitions

  • the invention relates to the protection of electrical circuits by means of safety equipment such as circuit breakers, and in particular the remote control devices of this type of equipment.
  • the invention particularly relates to an automatic remote reset and / or release device for a variable configuration protection system, the components and parameters of the remote control being optimized both in terms of reliability and functionality and cost.
  • An electrical circuit is usually protected by safety equipment that reacts under abnormal conditions.
  • breaker-type circuit breakers can be triggered in case of overload to isolate the problem line; Manual switching must then be performed to put the circuit back into service.
  • the triggering of a protective device may come from transient defects that disappear on their own; the switchgear can then be associated with automatic reset devices, or remotely, which perform one or more re-engagement tests.
  • FR-2 535 520 which is considered to be the closest state of the art, discloses a drive mechanism having the features of the preamble of claim 1.

  • One of the options is to stop the movement of the joystick after its dead point and complete the movement by its inertia. This solution can prove unreliable over time: in particular, after many maneuvers, the neutral position can be shifted; moreover, a constraint is created on the actuator, which can alter its operation, and, depending on their number, the auxiliaries are not controlled.
  • Another option is to force the handle against the housing, with a stop under stress: this solution involves efforts to strengthen the housing, and in any case, risky as to the long-term mechanical strength.

  • the mechanism comprises spring means so that the end of the second arm, which can be coupled to the lever, takes two different positions regardless of the position of the fastening means to the actuator.
  • the actuator can extend its stroke when the handle is in abutment, or vice versa.
  • the spring means are located on the second arm. They may comprise springs, preferably two, placed in appropriate housings, advantageously parallel, of the second arm which is formed of two telescopic parts relative to each other.

  • the actuation of the core 120 must also be able to rotate the handle 50 in the other direction, that is to say exerting a pull on the end of the base 53 of the handle 50, or a thrust on the other side of the pivot axis 52 of the handle 50: an additional device then proves necessary.

  • the connecting rod 160 presses the handle 50 which pivots the V-piece 172; when the rod 160 returns to the initial position, the handle 50 and the V-piece 172 remain in their position; at the end of the race, the connecting rod 160 manages to cross the switch 170 because of the force exerted by the actuating mechanism 150 and a relative flexibility of the second arm 175; a once the switch 171 exceeded, the V-shaped part 172 resumes its position, the force of the handle 50 and the rigidity of its first arm 175 being greater than the return force of the spring 166 coupling the rod to the lever; the connecting rod 160 thus pivots slightly toward the second trajectory of the etched guide 171.
  • the lever 151 When actuating the plunger core 120, as illustrated in FIG. figure 7E , the lever 151 is biased in rotation and the rod 160 in translation, but the etching 171 on the housing 21 directs the rod 160 to another part of the lever 50, in particular a bearing zone 58 located on the other side of its axis 52.
