A transfer switch device, which includes: a first movable contact, which has a connecting position and a disconnecting position respectively for connecting and disconnecting the electrical connection between a common power supply static contact and a first terminal of the load; a second movable contact head, which has a connecting position and a disconnecting position respectively for connecting and disconnecting the electrical connection between the static contact of the backup power supply and the second terminal of the load; the first connecting rod; the second connecting rod; the main shaft of the mechanism, which passes through the first The connecting rod is connected to the first movable contact and is connected to the second movable contact through the second connecting rod; the movement of the main shaft of the mechanism actuates the first connecting rod and the second connecting rod, so that the transfer switch device has the following working state : The first movable contact is in the connected position, and the second movable contact is in the disconnected position; the second movable contact is in the connected position, and the first movable contact is in the disconnected position; the third movable contact is in the disconnected position; The first movable contact and the second movable contact are in the off position at the same time. A multi-pole switching device includes a transfer switch device as described above.
Description
technical field [0001] The present disclosure relates to a transfer switch device, and further relates to a multi-pole switch device including the transfer switch device. Background technique [0002] The duty of the dual power supply automatic transfer switch is to ensure the power supply, and the reliability of the product is the technical index that users are most concerned about. Providing a simple and reliable transfer switch structure is very important to improve the reliability of the transfer switch, so it is the tireless pursuit of engineers in the industry. [0003] The existing changeover switch is a two-position changeover switch, and the two-position means that the moving contact of the changeover switch can only be switched between the static contacts of the power supply I and the power supply II, that is, the conversion time from the power supply I to the power supply II is determined by The design of the switch is given and fixed; its moving contact is alway...
