Problems solved by technology

The maintenance personnel usually use the operating handle of the earthing switch to operate the closing and opening of the earthing switch. If there is no interlocking mechanism between the operating handle of the earthing switch and the operating mechanism of the earthing switch, if the cabinet door is not closed, if misoperation will The grounding switch is disconnected, so that after the switchgear is powered on, it will bring great hidden dangers to personal safety and property safety.

Abstract

The invention relates to a switchgear and an interlocking mechanism between its grounding switch and the cabinet door. The interlocking mechanism includes a mounting frame, a main shaft rotatably arranged on the mounting A return spring is provided between the frames, a first stop structure is provided on the main shaft, a second stop structure and a step-off structure are provided on the chain shaft, the chain shaft has an end face for pushing the door, and the chain shaft is on the guide movement stroke After being pushed by the door, there is a locking position where the second blocking structure and the first blocking structure are blocked and matched in the circumferential direction, and an unlocking position where the abdication structure corresponds to the first blocking structure under the action of the return spring. When the cabinet door is opened, the chain shaft is under the action of the return spring, and the first stop structure and the second stop structure stop and cooperate. Personal safety or property damage due to misuse.

Description

technical field [0001] The invention relates to a switch cabinet and an interlocking mechanism between a grounding switch and a cabinet door. Background technique [0002] The grounding switch is an important component in the switchgear. Its function is to bypass equipment or lines to ensure that they are grounded when the equipment and lines are overhauled to ensure personal safety. [0003] According to the power protection requirements, maintenance personnel should first close the door panel of the switch cabinet after the maintenance work is completed, and then disconnect the grounding switch before the power transmission operation can be carried out. The maintenance personnel usually use the operating handle of the earthing switch to operate the closing and opening of the earthing switch. If there is no interlocking mechanism between the operating handle of the earthing switch and the operating mechanism of the earthing switch, if the cabinet door is not closed, if miso...
