Abstract

The invention discloses a locking device and transfer switching equipment using the same, and relates to the technical field of low-voltage apparatus, so as to improve the technical problem of fairlylow safety of existing locking device. The invention provides a locking device which comprises a hand-operated switching mechanism and a shell mechanism, wherein the hand-operated switching mechanismcomprises a main gear, a first switching gear and a second switching gear; the main gear is configured to drive the first switching gear or the second switching gear to rotate; a first interlocking column is arranged on the first switching gear and cooperates with the first switching gear to realize an interlocking effect when a main power supply is switched on; a second interlocking column is arranged on the second switching gear and cooperates with the second switching gear to realize an interlocking effect when a backup power supply is switched on; the shell mechanism comprises a slip coverand a handle box connected with the slip cover; a handle is arranged in the handle box; and after being taken out, the handle is used for driving the main gear to rotate.

Description

technical field [0001] The invention relates to the technical field of low-voltage electrical appliances, in particular to a padlock device and a transfer switch appliance using the same. Background technique [0002] Due to the process or use requirements, the equipment cannot be powered off during operation, and a transfer switch is required at this time. A transfer switch is an electrical appliance used to switch one or several load circuits from one power source to another when the power supply is interrupted, thereby ensuring continuous power supply. [0003] The transfer switch usually has three execution states: main power closing, backup power closing and double opening. In the double-point state, the transfer switch cuts off the two power supplies of the main power supply and the backup power supply at the same time to achieve the effect of disconnecting the power supply, so as to ensure that there will be no electric operation when the maintenance personnel manual...
