The invention discloses a switch cabinet grounding switch and cable chamber door mechanical locking control mechanism. A transmission rod and a crank arm are arranged between a grounding switch control mechanism and a grounding switch main shaft, and the left end of the transmission rod is hinged to the crank arm through a first pin; a lockset support is fixedly installed on the cabinet body, a zigzag-rule-shaped locking rod is installed on the lockset support, and the first section of the locking rod is coaxially and fixedly connected with a swing block. The cable chamber door is provided with a lock tongue piece, and the lock tongue piece is provided with a notch allowing the third section of the locking rod to be buckled therein. A reset spring is arranged between the swing block and the lock support. The mechanism is also provided with a swing plate and a pressing rod. The pressing rod can swing around the first section of the locking rod; a second pin is fixedly connected to the right end of the pressing rod and inserted into the long hole of the swing plate. The swing block is fixedly connected with a folded edge which is located under the pressing rod. The pressing rod is fixedly connected with a pressing block. The grounding switch main shaft can be independently prevented from rotating under the condition that the cable chamber door is opened.
Description
technical field [0001] The invention belongs to the technical field of fixed switch cabinets, and in particular relates to a mechanical locking control mechanism for a ground switch and a cable room door of a switch cabinet. Background technique [0002] There is a cable room in the switchgear of electrical equipment, and a grounding switch is installed in the cable room. The grounding switch is equipped with a grounding switch spindle and a knife switch.
