Description

Technical Field

[0001] The utility model relates to the technical field of distribution boxes, in particular to a distribution box with a protection function. Background Art

[0002] A distribution box is an electrical device used to distribute, control and protect electrical energy. It usually contains switchgear, measuring instruments, protective electrical appliances and auxiliary equipment, which are assembled in a closed or semi-closed metal cabinet or on a screen to form a low-voltage distribution box. Its main function is to reasonably distribute electrical energy, facilitate circuit opening and closing, and provide safety protection.

[0003] During the actual operation of the distribution box, due to the continuous operation of the internal electrical components, significant heat energy will accumulate. Especially under high load or long-term operation, if the heat dissipation is poor, the temperature inside the box may rise rapidly to a dangerous level and cause a fire. In addition, when the distribution box encounters external voltage fluctuations or internal faults, the risk of overvoltage will also increase. Under the combined effect of heat energy accumulation and overvoltage danger, the internal environment of the distribution box becomes extremely unstable. Once the safety threshold is exceeded, serious accidents such as flames or explosions may occur. If not handled in time, it will cause direct damage to other electrical components inside the distribution box, and it is more likely to spread through the circuit, causing a chain reaction to the entire power system, leading to more extensive failures and damage.

[0004] Therefore, there is an urgent need to provide a distribution box with a protective function to solve the above problems. Utility Model Content
