Abstract

The invention discloses a normally-closed power distribution cabinet which belongs to the technical field of power distribution cabinets, and aims to provide the normally-closed power distribution cabinet with good locking performance. The normally-closed power distribution cabinet is characterized by comprises a cabinet body and a cabinet door, wherein the inner wall of the cabinet door is connected with a first locking component, and the inner wall of the cabinet body is connected with a second locking component; the second locking component comprises a second lock body, a second swinging component, a second connecting rod, a second clamping shaft and a second clamping groove; the first locking component comprises a first lock body, a first swinging component, a first connecting rod, a first clamping shaft and a first clamping groove; the second clamping shaft can be clamped in the first clamping groove, and the first clamping shaft can be clamped in the second clamping groove, thereby realizing locking of the cabinet door; and a resetting mechanism used for keeping the cabinet door normally-closed is further arranged between a pivoting ring of a pivoting device and the pivoting device. The normally-closed power distribution cabinet is applicable to power distribution cabinets.

Description

technical field [0001] The invention belongs to the technical field of power distribution cabinets, and relates to a power distribution cabinet with lockable cabinet doors. Background technique [0002] Power distribution cabinets (boxes) are divided into power distribution cabinets (boxes), lighting distribution cabinets (boxes), and metering cabinets (boxes), which are the final equipment of the power distribution system. The power distribution cabinet is a general term for the motor control center. The power distribution cabinet is used in the occasions where the load is relatively scattered and there are few circuits; the motor control center is used in the occasions where the load is concentrated and there are many circuits. They distribute the electric energy of a certain circuit of the upper-level power distribution equipment to the nearest load. This level of equipment shall provide protection, monitoring and control of the load. [0003] In addition to satisfying...
