Description

Technical Field

[0001] The invention relates to the technical field of electrical equipment, in particular to an automatic electrical control box capable of rapidly dissipating heat. Background Art

[0002] An electrical control box is a box device used to control electrical equipment. It is usually made of metal or plastic. It is mainly used to centrally install switchgear, measuring instruments, protective electrical appliances and auxiliary equipment, so as to control, monitor and protect the power system. In the power system, the electrical control box plays a vital role. Various electrical components such as circuit breakers, contactors, relays, mutual inductors, etc. are installed inside. These components achieve precise control of the power system through reasonable layout and connection. For example, in industrial production, the electrical control box can be used to control the start, stop and turn of the motor, as well as adjust the equipment. Running speed and power. In addition, the electrical control box also has protection functions such as overload, short circuit, and leakage. When an abnormal situation occurs in the power system, it can cut off the power supply in time to protect the safety of equipment and personnel. There are many types of electrical control boxes. According to different application scenarios and needs, you can choose control boxes of different types and specifications. For example, there are waterproof control boxes suitable for outdoor environments, and there are special control boxes suitable for high or low temperature environments. At the same time, with the advancement of science and technology, electrical control boxes are also constantly upgrading and improving, such as the introduction of intelligent control systems to achieve remote monitoring and management, which improves the operating efficiency and safety of the power system.

[0003] The electrical control box needs to be cooled when in use. If the electrical control box is not cooled, a series of problems may occur. For example, the electrical control box contains a large number of electrical components, such as circuit breakers, contactors, relays, etc. These components will generate heat during operation. If the control box does not dissipate heat effectively, the heat will accumulate in the box, causing the temperature of the components to rise. When the temperature exceeds the rated operating temperature of the components, it will accelerate the aging of the components and shorten their service life. In a high temperature environment, the insulating materials of electrical components are prone to aging, resulting in a decrease in insulation performance, which in turn causes electrical faults such as short circuits and leakage. In addition, high temperatures may also increase the contact resistance of electrical components, affect the normal operation of the contactor, and even cause fire accidents. In summary, if the electrical control box is not cooled, it will lead to a series of problems such as component overheating, system failure, decreased control accuracy, increased safety hazards, and increased maintenance costs. Therefore, in order to ensure the normal operation of the electrical control box and extend its service life, effective heat dissipation measures must be taken.

[0004] Currently, in actual use, the electrical control box is provided with heat dissipation vents on all sides. However, this unpowered heat dissipation method has poor heat dissipation effect inside the box during the period of heat accumulation, and the heat dissipation method cannot be adjusted according to actual use, which is not conducive to actual use.

[0005] In view of this, this application is hereby filed. Summary of the invention
