Description

Technical Field

[0001] This utility model relates to the field of power distribution equipment cabinet lock technology, specifically a power distribution equipment door lock with an alarm for live casing. Background Technology

[0002] The door lock of the distribution cabinet is a mechanism that electrical equipment needs to be frequently operated. When the casing of the electrical equipment becomes energized due to a fault or accident, it is generally difficult to detect in time because there is no detection warning alarm device or obvious leakage characteristics. This can pose a danger to the operator. When an unsuspecting operator touches the door lock handle directly, it can cause panic at best, and damage to the equipment and safety at worst.

[0003] For example, patent number 201921780053.4, entitled "A Door Lock for an Equipment Cabinet," includes a lock base on the cabinet door. A cavity is formed through the lock base, and a rotating shaft is disposed within the cavity. One end of the rotating shaft extends out of the cavity and passes through the cabinet door. A fixing pin is provided at the end of the rotating shaft passing through the cabinet door for locking inside the cabinet. The end of the rotating shaft away from the fixing pin is located within the cavity and has a driving block. The driving block is arrow-shaped, and the arrow direction of the driving block is consistent with the direction of the fixing pin. The arrow shape of the driving block means that when the cabinet is locked, the arrow of the driving block is horizontal; when the cabinet is open, the arrow of the driving block is vertical. This makes it easy to determine from the outside whether the cabinet is locked, eliminating the need for sequential checks and saving time and effort.

[0004] However, existing equipment door locks lack leakage current detection and alarm structures, which could lead to workers touching live equipment cabinets and endangering their lives. Therefore, they do not meet the current needs. In response, we have proposed a power distribution equipment door lock with an alarm for live casing. Utility Model Content
