Definitions

  • the present invention relates to modular devices, more particularly, the present invention relates to kinematic for auxiliary modular devices, such as overvoltage, under-voltage and shunt trip, using such kinematic.
  • auxiliary modular devices in the art such as those for shunt-trip, under-voltage and over-voltage use one dedicated kinematic for allowing each of their operation. In some solutions kinematic is also used for performing an indication action.
  • the kinematic is coupled with an "active component", useful for allowing the device to perform its particular function. Relays and coils are the examples of such active component.
  • a relay may be used for various under-voltage devices, and a coil with a dedicated electronic board may be used for shunt-trip and over-voltage devices.
  • auxiliary devices A common drawback of the auxiliary devices is that each modular device has to be designed with its specific components for its own kinematic. This implies that different production machines, moulds and procedures would be required for each modular device. Therefore, this gives rise to the need of a quite complex storehouse management and hence mass cost reduction may not be possible to achieve.
  • the kinematic link includes a first link, a second link, a pin, a connecting spring and a indicator flag.
  • the second link is connected to the first link.
  • the pin is connected to the second link.
