Abstract

The invention discloses a locking indicating device of a changeover switch. The locking indicating device comprises a bracket, a microswitch base which is arranged on the bracket, a microswitch which is arranged below the microswitch base, a cover plate, a handle locking component, a changeover transmission component and a display component. The changeover transmission component is mounted on the bracket. The cover plate is fixed on the bracket through a vertical column and is located above the changeover transmission component. The handle locking component is mounted above the cover plate. Three gears of the changeover transmission component cooperate with one another for finishing changeover between a main power supply and an auxiliary power supply. Furthermore a straight rack of the display component engages with the gear and is used for displaying the state of the switch. Furthermore a handle can touch the microswitch through operation, thereby representing a manual state; simultaneously a locking board is extracted from the handle, and locking can be performed. The locking board of the locking indicating device of the changeover switch cannot be opened on the condition that the changeover switch is not totally in a double-separation position, and a locking action cannot be finished, thereby improving safety of the device.

Description

technical field [0001] The invention belongs to the field of low-voltage electrical appliances, in particular to a padlock indicating device for a transfer switch. Background technique [0002] For transfer switch appliances that provide a two-way position, the standard requires a padlock device. Lock it in the double-opening position to ensure the safety of the operation at the load end, so the padlock device must be reliable to ensure the personal safety of the operator. When the padlock device of the existing transfer switch is not completely in the double-open position, the padlock work can still be completed, which has potential safety hazards. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a padlock indicating device for a changeover switch. When the changeover switch is not completely in the double position, the padlock plate cannot be opened and the padlock action cannot be completed, thereby impro...
