Description

A rain-proof power distribution cabinet with a freely expandable cabinet top

technical field

The utility model relates to the technical field of electric power devices, in particular to a rainproof electric power distribution cabinet whose top can be freely expanded.

Background technique

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. The first-level power distribution equipment is collectively referred to as the power distribution center. They are centrally installed in the substation of the enterprise, and distribute the electric energy to the lower-level power distribution equipment in different locations. This level of equipment only relies on step-down transformers, so the requirements for electrical parameters are relatively high, and the output circuit capacity is also large; the second level of power distribution equipment is the collective name of power distribution cabinets and motor control centers. The power distribution cabinet is used in the occasions where the load is 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 should provide protection, monitoring and control for the load; the final level of power distribution equipment is collectively called the lighting power distribution box. They are far away from the power supply center and are scattered small-capacity power distribution equipment.

The distribution cabinet, the box in which the electrical appliances and their routes are placed, is used to distribute power energy. The distribution cabinet is usually placed outdoors. If it encounters a harsh environment, it will generally bring inconvenience to the maintenance of the distribution cabinet. , when the maintenance personnel repair the power distribution cabinet on a rainy day, it is easy to cause rainwater to enter the power distribution cabinet and damage the equipment in the power distribution cabinet. Contact with internal equipment can easily lead to the risk of electric shock due to moisture.
