Embodiment Construction

[0035] Electrical cabinets can be divided into power electrical cabinets, lighting electrical cabinets and metering cabinets, which are the final equipment of the power distribution system. In the process of using the electrical cabinet, in order to improve its safety performance, it is generally equipped with a grounding switch. The grounding switch is to ensure personal safety and equipment safety. Connect to the earth through the grounding device.

[0036] Yet with regard to prior art, the locking device of switchgear is not perfect yet, for example, when the electric cabinet contains grounding switch, the back door of electric cabinet is opened, then may disconnect the grounding switch of electric cabinet, at this moment If the staff does not know and proceeds to the next dangerous operation, it will increase the accident rate of the staff when operating the electrical cabinet.

[0037] Based on this, the present application provides a locking device for an electrical cab...

Abstract

The embodiment of the invention discloses a locking device of an electrical cabinet. The locking device is used for reducing the accident rate caused by disconnection of a grounding switch by keeping the state of the grounding switch. The locking device is applied to the electrical cabinet, and the electrical cabinet comprises a grounding switch, an electrical cabinet door and an electrical cabinet shell. The locking device comprises a lock seat, a positioning buckle structure, a pull rod structure, a cover plate, a first pressing plate, a second pressing plate and a connecting rod; the first pressing plate and the second pressing plate are fixedly arranged on the electrical cabinet shell; the lock seat is fixedly installed on the first pressing plate, and the positioning buckle structure is hinged to the lock seat; the pull rod structure is fixedly installed on the second pressing plate and used for controlling the moving speed of the cover plate; one end of the connecting rod is hinged to one side of the cover plate, and the other end of the connecting rod is fixedly connected with the pull rod structure; a lock hole is formed in the other side of the cover plate and is used for accommodating the positioning buckle structure; and when the electrical cabinet door is in an open state, the positioning buckle structure is used for being locked with the lock seat so as to fix the position of the cover plate.

Description

technical field [0001] The embodiments of the present application relate to the field of electric locks, in particular to a locking device for an electric cabinet. Background technique [0002] The electrical cabinet is the supporting equipment in the power distribution equipment, which is composed of the shell, steel structure and various mounting panels, components, instruments, measurement and control devices and cables. The function of the electrical cabinet is to distribute electric energy to various load parts by power distribution control, and to perform power-off protection when the circuit is short-circuited, overloaded and leaked. [0003] The mechanical locking of the electrical cabinet is an important measure to ensure the safe operation of the power grid, ensure equipment and personal safety, and prevent misuse. However, as far as the prior art is concerned, the locking device of the switch cabinet is not perfect. When switching, if the back door of the electri...
