Description

Technical Field

[0001] The utility model relates to the technical field of electric power fire protection, in particular to an electric power construction electric power fire protection device. Background Technique

[0002] The electric power project is related to the production, transmission and distribution of electric energy. A large part of the personal electric shock and system failures caused by the power system are due to the large leakage current of equipment and lines. When the leakage current is serious, it will burn out electrical equipment or lines and cause a fire. Therefore, the electrical safety issue has become a top priority related to personal safety and equipment safety. The electrical cabinet is an important part of the electric power project. The electrical cabinet is used to set up components such as electrical equipment and components. A large amount of heat will be generated by the components in the electrical cabinet during use. If this part of the heat is not discharged in time, it will cause the temperature inside the electrical cabinet to be too high. When the inside of the electrical cabinet is in a high temperature state for a long time, the internal electrical components are easily damaged, which will then lead to a short circuit and fire in the circuit. If the fire is not extinguished, the consequences will be unimaginable.

[0003] When the electrical cabinet catches fire, the flames will overflow through the filter screen and spread around, causing the fire to expand. At the same time, the outside air will also enter the electrical cabinet through the filter screen, fueling the fire.

[0004] Therefore, it is necessary to provide an electric power construction electric power fire protection device to solve the above technical problems. Content of the Utility Model
