Patent

CA 2174084

The invention relates to a shield which prevents squirrels or other animals from causing faults in power distribution substations. Switch and bus insulators are primary points of contact when a small animal crawls from a grounded, supporting structure across an insulator to an energized conductor. The present invention provides for a barrier on switch and bus insulators which prevents animals from coming into contact with a grounded structure and an energized conductor simultaneously, thus eliminating a ground path from the energized conductor through the animal to the grounded structure.

L'invention concerne un dispositif de protection (118, 124) qui empêche les écureuils ou d'autres animaux d'endommager des stations de distribution d'électricité. Les isolants de commutateurs et de bus sont les principaux points de contact lorsqu'un petit animal passe par un organe de support (102) mis à la terre, pour s'introduire dans un isolant (108, 112), et pénétrer jusqu'à un conducteur sous tension (104, 106). L'invention fournit une barrière (118, 124) sur des isolations de commutateurs et de bus (108, 112) qui empêche les animaux d'entrer simultanément en contact avec un organe mis à la terre (102) et un conducteur sous tension (104, 106), éliminant ainsi un trajet par la terre allant du conducteur sous tension (104, 106) jusqu'à l'organe mis à la terre (102) et passant par l'animal.
