Description

Technical Field

[0001] The utility model belongs to the technical field of power distribution cabinets, and in particular relates to a power distribution cabinet with an early warning function. Background Art

[0002] A distribution cabinet is a power system device that receives electrical energy from the main power supply and distributes it to different circuits and devices. Its functions include the distribution, control and protection of electrical energy to ensure that electrical energy is safely and efficiently transmitted and used within a building or facility. The distribution cabinet plays a key role in the power system, maintaining the stable operation of the system by monitoring and managing the flow of electrical energy, while ensuring the safety of equipment and personnel.

[0003] Many electrical components are usually installed in a distribution cabinet. The electrical components will generate a certain temperature during operation. When these electrical components are in a high-load state for a long time, the temperature generated will cause the temperature in the closed space of the distribution cabinet to rise sharply, which is easy to cause damage to the electrical components. In severe cases, a fire may occur, which is very dangerous. However, the existing distribution cabinets do not have an early warning function. Therefore, a distribution cabinet with an early warning function is proposed to solve the above problem. Utility Model Content

[0043] During actual use, when the electrical components installed in the cabinet 1 are under high load for a long time, the temperature rises sharply. When several temperature sensors 10 arranged inside the cabinet 1 detect that the temperature is too high, the information is fed back to the controller 22. When the controller 22 receives the information, the buzzer 23 is controlled to alarm and remind the staff. At the same time, the controller 22 controls the two first fans 13 and the two second fans 35 to turn on to cool down the cabinet 1. Then the driving motor 30 is controlled to drive the driving motor 30 to drive the threaded screw 31 at the output end to rotate. When the threaded screw 31 rotates, the sliding sleeve 32 arranged on the outside of the threaded screw 31 engages and slides to drive the external sliding block 33 to slide radially within the stroke range of the threaded screw 31, so that the sliding block 33 drives the mounting frame 34 on one side and the two second fans 35 installed on one side of the mounting frame 34, and with the assistance of the two sliding rods 361 and a sliding block 362, the two second fans 35 finally perform reciprocating up and down cooling on the inside of the cabinet 1 to keep the electrical components within a safe working temperature range.
