Description

An assembled temperature self-control waterproof power distribution cabinet

technical field

The invention relates to the technical field of power distribution equipment, in particular to an assembled temperature self-control waterproof power distribution cabinet.

Background technique

Distribution cabinet, a box in which electrical appliances and their wiring are placed to distribute electrical energy. 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. Its classification is generally divided into first-level power distribution equipment, collectively referred to as 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 relatively large. Secondary power distribution equipment is a general term for power distribution cabinets and motor control centers. 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 final power distribution equipment is collectively referred to as the lighting power distribution box. They are far away from the power supply center and are scattered small-capacity power distribution equipment.

However, it is very troublesome to disassemble the general power distribution cabinet after installation, which is not conducive to replacement and maintenance. Ordinary power distribution cabinets are fastened by screws. In this way, the screws are often easy to rust for a long time, which is even more inconvenient. Easy to disassemble. Moreover, due to the many functions and the large volume of the existing power distribution cabinets, the components are usually welded together when leaving the factory, so the transportation is extremely inconvenient. After arriving at the installation site, the installation will also be inconvenient due to the size and weight problems.

In addition, the power distribution cabinets used in power plants and substations should meet the relevant requirements of the GB3906-1991 "3-35 kV AC metal-enclosed switchgear" standard. In the working state of high current, the contact resistance increases due to factors such as surface oxidation, corrosion, loosening of fastening bolts, and aging of contacts at the junction of dynamic and static contacts and the connection of busbars, which causes the temperature of the contacts or joints to rise. The degree of overheating will continue to increase, which will affect the insulation performance and equipment life. In addition, due to the sealed structure of the power distribution cabinet, the temperature of the electronic components in the power distribution cabinet will gradually rise. When the working temperature of the components is lower, the electronic components in the power distribution cabinet will fail, which will make the power distribution cabinet unable to operate normally. The heat dissipation effect of the existing power distribution cabinet is not good, and the heat loss cannot be automatically controlled.
