INSULATOR PROTECTION DEVICE FOR POWER TRANSMISSION TOWER Russian patent published in 2015 - IPC H01B17/50 

FIELD: electricity.

SUBSTANCE: insulator protection device for power transmission tower comprises a case 1 having part 2 shaped as a hood with part 3 placed at its edge along the perimeter and shaped as a conical skirt oriented by its geometric peak towards part 2. Case 1 is made of two halves 4, 5 matched over the plane placed along the longitudinal axis of case 1. Halves 4, 5 are interconnected by axial hinged joint 6 and latches 8 made at part 3. In lateral sides of part 2 at opposite sides there are openings 16; each opening is of rounded three-rayed shape where two rays pass to opposite sides along the edge matched with part 3 while the third ray passes in direction between them to the peak of part 2. Each opening 16 is placed with their symmetrical parts in both halves 4, 5 symmetrically in regard to the plane of their matching.

EFFECT: expanding range of devices for protection of base and pin insulators for power transmission towers with a compact-size device fixed directly at insulator and providing bird guard.
