Plug-and-play switch operating mechanism

Abstract

The invention belongs to the technical field of low-voltage power distribution, and particularly relates to a plug-and-play switch operating mechanism. According to the technical scheme, the plug-and-play switch operating mechanism comprises a fixing plate, a plurality of limiting baffles are arranged on the fixing plate, an installation mechanism is arranged between the fixing plate and the limiting baffles, a switch function unit is connected to the installation mechanism, and a pushing mechanism used for pushing the switch function unit is connected to the fixing plate; and the switch function unit is slidably connected with an opening and closing indication mechanism, the opening and closing indication mechanism blocks the connection position of a toggle handle of the switch function unit when moving to one limit position, and the opening and closing indication mechanism blocks the position of the propelling mechanism after propelling when moving to the other limit position. The plug-and-play switch operating mechanism can perform plugging operation on a single switch function unit and ensure that the switch function unit is in a power-off state during operation.

Description

technical field [0001] The invention belongs to the technical field of low-voltage power distribution, and in particular relates to a plug-and-play switch operating mechanism. Background technique [0002] The switch functional unit includes a circuit breaker and a plug-in box connected to each other. When working, the plug-in box is plugged into the busbar chamber valve, and the circuit breaker can be opened and closed. When the switch functional unit needs to be overhauled, the switch functional unit must be powered off, and then the switch functional unit is taken out, that is, the toggle handle of the circuit breaker must be toggled to the off position. [0003] In the prior art, a drawer is used to install the switch function unit, and when a certain switch function unit needs to be overhauled, the drawer is pulled out as a whole. However, when using the drawer cabinet to install the switch functional unit, a single switch functional unit that needs to be repaired cann...

AI Technical Summary

Problems solved by technology

However, when the switch functional unit is installed with a drawer cabinet, a single switch functional unit that needs to be repaired cannot be taken out, which is inconvenient to operate

Moreover, the cost of the chest of drawers is high and the structure is complicated

[0004] If a switch functional unit is plugged and pulled separately, it cannot be guaranteed that the toggle handle of the circuit breaker is in the disconnected state when plugged and pulled

If the operator forgets to turn the toggle handle to the off state when plugging the switch function unit relative to the busbar compartment valve, it will cause a greater safety risk
