Title: Anti-arc safety switch for pantograph - with heat sensitive switch to short protective contact horns after set time of arc burn
Inventor: HOECKELE MAX
IPC: B60M1/18
Filed: 1973-09-08
Abstract: When a pantograph slides across the separating joint of two track sections an arc can be set up across the protective horns between the two ends of the insulator. This arc can persist due to phase differences and can lead to overheating, and damage, of the insulator between the front and rear ends of the pantograph. A safety switch is fitted and operates either on the light output, or more simply, on the heat output from the arc. The switch shorts out the two horns and restores the stability of the pantograph. After cooling it is reset. A simple system would have a heat expanding fluid, or even air in a membrane sealed container to operate the shorting contact. The system prolongs the life of the pantograph, especially in high power systems.
