Abstract

A disconnector with an anti-icing arrangement includes a main blade moving contact, a main blade arm, a main blade static contact, a main blade transmission arrangement and a main blade anti-icing arrangement. The main blade transmission arrangement is adapted for driving the main blade arm to move. The main blade anti-icing arrangement includes a main blade anti-icing shield and a main blade anti-icing shield transmission arrangement. The main blade anti-icing shield transmission arrangement is adapted for drive the main blade anti-icing shield such that the main blade anti-icing shield shields the main blade moving contact in an opened position to keep ice and snow and rainwater from covering a surface of the main blade moving contact, and moves away from the main blade moving contact in a closed position, to enable the main blade moving contact to be contacted with the main blade static contact.
