Description

Technical Field

[0001] The utility model belongs to the technical field of mine distribution boxes, and in particular relates to a mine distribution box. Background Art

[0002] As a key component of the power system, the distribution box is used to receive electrical energy from the ground or external transmission lines and distribute it to various equipment and power points in the mine. The role of the distribution box in the mine is crucial, and it bears multiple responsibilities such as electrical safety protection, operation monitoring and emergency response, ensuring the safety and stable operation of the power system inside the mine;

[0003] Distribution boxes are usually designed with air circulation systems, which exhaust hot air through built-in fans or air circulation devices, and introduce cooler air from the outside to maintain the internal temperature stable and realize the heat dissipation function of the distribution box. Inside the mine, the dust content in the air may be quite large. In mining and mine operations, these dusts will cause various problems. Although the mine is equipped with dust reduction and dust removal equipment, there are still a lot of dust particles in the air. These dust particles enter the distribution box with the airflow. The accumulation of dust may cause short circuits or insulation breakdown between electrical components, thereby causing electrical failures and affecting the normal operation of the distribution box. Excessive accumulation of dust inside electrical equipment may cause equipment overheating and even cause fire or explosion. In addition, the accumulation of dust will also affect the heat dissipation and ventilation effects of the distribution box, causing the equipment temperature to be too high and reducing the stability and life of the equipment.
