Abstract

This moving type pushing continuous drawer functional unit for low voltage switch cubicle comprises a functional unit base, on which placed are moving type parts, pushing mechanism and position linkage releasing mechanism. On functional unit base and moving type parts erected are moving type plug-in units. Under the force of pushing mechanism realized are separation, testing and connection between vertical bus, main circuit stationary plug-in units, auxiliary circuit stationary plug-in unit, i.e. keeping wire in the fixed condition, needing only varying plug-in units. On the condition of closed door of switch cubicle, the functional unit of separation condition, while when the door is not open, the condition varies to testing condition and connecting condition, meeting the requirements of IP40 protection grade.

Description

technical field [0001] The invention relates to a drawer function unit for a low-voltage withdrawable switchgear, especially a movable push-in continuous unit that does not move the drawer, moves the plug, does not move the wire, locks the drawer, and does not open the unit door during operation. Drawer functional unit. Background technique [0002] At present, the protection level of the functional units produced in China does not meet the protection level requirements of IP40 when the functional units are separated and in the test position, and the functional unit lock is not reliable in the test position, which is prone to misoperation. Contents of the invention [0003] In order to overcome the deficiency of the drawer function unit of the existing low-voltage withdrawable switchgear, the present invention provides a movable push continuous drawer function that can be reliably locked in separation, test, and connection positions, and has position locking during operati...
