LYE102 JN15-12 Indoor AC Isolation Switches High Voltage Earthing Switch With Sensor

Structure of LYE102 JN15-12 Indoor AC Isolation Switches High Voltage Earthing Switch With Sensor

Main structure: The earthing switch has a bracket, grounding knife assembly, static contact, sensor, shaft, inflection arm, pressure spring, conductive casing and soft connection.
Note: The bracket is bent from a thin steel plate and welded into parts, the rest are assembled parts.

Working principle of LYE102 JN15-12 Indoor AC Isolation Switches High Voltage Earthing Switch With Sensor

a. When operating the operating mechanism to close the earth switch, as the torque makes the spindle overcome the resistance torque, drive the inflection arm to rotate along the closing direction, and make the manipulating rod on the earth knife pass through the dead point of the pressure spring, the pressure spring releases energy to make the earth switch close quickly, in the closing position. The grounding knife on the grounding knife assembly is firmly and reliably contacted by the disc spring and the flange part of the static contact.
b. When the switch is opened, the moment of action causes the spindle to overcome the main moment and the spring force, driving the inflection arm to rotate in the direction of opening and causing the grounding knife pressure spring to pass through the dead point and the pressure spring energy storage to end for the next closing.
c. The grounding switch and the closing speed are independent of the operating speed of the person.
