Lightning induction-type solid-phase arc-extinguishing lightning protector

A lightning induction-type solid-phase arc-extinguishing lightning protector, fixedly mounted at one end of an insulator string by means of a link fitting, comprising:

• a lightning protector housing,
• an arc-extinguishing rotating disk,
• a conductive metal plate,
• a planar torsion spring,
• an arc-striking rod,
• a fastening rod,
• an inductive coil,
• an arc-extinguishing cylinder,
• a counter arm,
• an upper cover and a rotating shaft;
• wherein an air-jet member triggering position is provided at the bottom of the lightning protector housing, and the arc-extinguishing cylinder is mounted below the air-jet member triggering position;
• the fastening rod is fixedly mounted at the edge of the air-jet member triggering position;
• the arc-striking rod has one end connected to the link fitting and the other end extending through the inductive coil to the arc-extinguishing cylinder;
• one end of a first wire of the inductive coil is connected to the fastening rod, the other end thereof slidably contacts the conductive metal plate;
• the arc-striking rod passes through the inductive coil, the counter arm is provided below the lightning protector housing and fixed to an axis position of the arc-extinguishing rotating disk;
• the arc-extinguishing rotating disk is mounted within the lightning protector housing, a center position of an upper portion of the arc-extinguishing rotating disk is connected to the upper cover of the lightning protector housing via the rotating shaft, the arc-extinguishing rotating disk can rotate around the rotating shaft, and the planar torsion spring for rotating the arc-extinguishing rotating disk is provided at a central position of the arc-extinguishing rotating disk, a lower portion of the arc-extinguishing rotating disk is in direct contact with a protruding gasket provided at the arc-extinguishing cylinder within the lightning protector housing, and has a gap with a non-protruding portion within the lightning protector housing;
• the conductive metal plate is mounted at the upper portion of the arc-extinguishing rotating disk;
• several arc-extinguishing air-jet members are provided around a circumferential direction of the arc-extinguishing rotating disk, each of the arc-extinguishing air-jet members is provided with an L-shaped trigger electrode and a recess on one side thereof, and the L-shaped trigger electrode has one end connected to one of triggering ends of the arc-extinguishing air-jet member by means of a second wire, and a rear portion of the L-shaped trigger electrode extends beyond an edge of the arc-extinguishing rotating disk;
• and
• the other triggering end of the arc-extinguishing air-jet member is connected to the conductive metal plate via a third wire.
