Abstract
The invention relates to a permanent-magnetic vacuum one-way switch. The permanent-magnetic vacuum one-way switch comprises a shell, a vacuum breaker and a permanent-magnetic driving mechanism, wherein the vacuum breaker comprises a static contact end and a moveable contact end; the permanent-magnetic driving mechanism drives the moveable contact end to be closed with the static contact end; the permanent-magnetic driving mechanism comprises an insulator; the moveable contact end is sleeved with a reaction spring; the moveable contact end is in moveable fit with the insulator; and the permanent-magnetic driving mechanism drives the moveable contact end to be closed with the static contact end through the insulator. Because of the moveable fit between the moveable contact end and the insulator, a connecting rod is not required and the moveable contact end is in indirect connection with the insulator; during action, the permanent-magnetic driving mechanism drives the insulator to move and the insulator presses against the moveable contact end to make the moveable contact end move along with the insulator, so that the moveable contact end is closed with the static contact end; the movement resistance caused by the rustiness of the connecting rod is avoided; in a wet underground environment, the using safety can be also ensured; moreover, the moveable fit enables the moveable contact end and the static contact end to be concentrically aligned with each other automatically, so that the contact during the closure is complete and sufficient.
Description
Technical field
