A contact device according to an embodiment includes: a fixed contact assembly including a first fixed contact and a second fixed contact; and a moving contact assembly including a first moving contact and a second moving contact. The moving contact assembly includes: a first moving member; and a second moving member. The second moving member is arranged, in a first direction, between the first moving member and the fixed contact assembly and fixed to the first moving member at one end in a second direction intersecting with the first direction. The first moving contact and the second moving contact move as the first moving member moves. A first distance from the one end in the second direction to the first moving contact is longer than a second distance from the one end in the second direction to the second moving contact.

The present invention provides a disconnector with an anti-icing arrangement, including 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. The disconnector of the present invention has simple structure, convenient installation and strong adaptability, which greatly improves stability and reliability of the disconnector in alpine regions.
