Description

Technical Field

[0001] The invention relates to the technical field of central cabinet heat dissipation, and in particular to a central cabinet heat dissipation structure for a substation. Background Art

[0002] The central cabinet of the substation is a key device for power distribution and control in the tire production process. It contains many electrical components such as circuit breakers, disconnectors, and mutual inductors. In large tire production enterprises, when large equipment such as vulcanizers are started and operated, a large amount of electric energy will be obtained from the central cabinet, causing the electrical components in the central cabinet to be in a high-load working state for a long time. If the heat generated cannot be dissipated in time, the temperature in the cabinet will rise. High temperature will reduce the conductivity of the contact material of the circuit breaker and increase the contact resistance. The increase in contact resistance will increase the voltage drop across the contact, further increase the heat generation, and form a vicious circle. Moreover, excessive temperature will also reduce the insulation performance of the insulating material. The insulating material in the central cabinet is usually an organic polymer material. Generally speaking, the life of the insulating material will be shortened by about half for every 10°C increase in temperature. When the insulation performance decreases, it may cause a short circuit fault, posing a serious threat to the power supply safety of tire production. Substations generally need to be equipped with a heat dissipation structure to cool the inside of the central cabinet.

[0003] The existing device mainly dissipates heat from electronic components through air cooling components. The existing technology is similar to a central cabinet heat dissipation structure. The structure with patent number CN220156052U includes a cabinet, a heat dissipation mechanism is provided on the front surface of the cabinet, and a dust removal mechanism is provided on the top of the cabinet. The central cabinet heat dissipation structure, through the heat dissipation mechanism, through the heat dissipation fan that is easy to install and disassemble, when the heat dissipation fan is damaged due to long-term overload work, it can be disassembled and repaired in time, thereby achieving the purpose of convenient maintenance. The heat dissipation fan rotates, and the heat dissipation fan can transport external cold air to the inside of the cabinet, thereby achieving the purpose of heat dissipation of the cabinet. Through the dust removal mechanism, the motor drives the second flat gear and the first flat gear to rotate, and drives the scraper to rotate. At this time, the scraper can scrape the dust on the surface of the dustproof net to avoid the phenomenon of clogging the dustproof net due to excessive dust, ensuring that the dustproof net achieves its own heat dissipation purpose, but the device still has room for optimization.

[0004] The existing device mainly uses the air cooling component to dissipate the heat of the central cabinet, which makes it easy for some devices to drive water vapor into the interior of the central cabinet, thereby causing some electronic components to rust and age easily. Secondly, some devices mainly fix the heat dissipation component inside the machine body, making it difficult for some devices to evenly guide the air to the electronic components inside the central cabinet, thereby causing it difficult to evenly dissipate the heat of some electronic components. Furthermore, some devices mainly use a scraper to clean the dust on the dustproof net, making it difficult for some devices to clean the dust inside the filter holes, making it difficult for some filters to be cleaned. Finally, some devices mainly fix the water cooling component on the machine body, making it difficult for some devices to quickly disassemble and assemble the water cooling structure of the heat dissipation component, thereby making it inconvenient to maintain the water cooling structure of the heat dissipation component, reducing the working efficiency and practicality of the device. Therefore, in order to solve the above problems, a heat dissipation structure of the central cabinet of a substation is proposed. Summary of the invention
