Structure:

  • Main Structure: Includes a bracket, grounding knife assembly, static contact, sensor, shaft, inflection arm, pressure spring, conductive casing, and soft connection.

Working Principle:

  • Closing Operation: When closing the earth switch, the torque overcomes resistance torque, driving the inflection arm to rotate and quickly close the earth switch. The grounding knife securely contacts the static contact.
  • Opening Operation: When opening the switch, the moment of action rotates the inflection arm in the opening direction, preparing the grounding knife for the next closing.
  • Independent Speed: The grounding switch operates independently of the operator’s speed.
