Description

Technical Field

[0001] The utility model relates to the technical field of low-voltage cabinets, in particular to a shock-absorbing low-voltage cabinet with an air-cooling flow channel. Background Art

[0002] The rated current of the low-voltage distribution cabinet is AC 50Hz, and the rated voltage is 380V. The distribution system is used for power, lighting and power distribution. The product has the characteristics of strong breaking capacity, good dynamic thermal stability, flexible electrical scheme, convenient combination, strong series and practicality, and novel structure.

[0003] Currently, most low-voltage cabinets are directly installed and used. When the working environment generates vibrations, the distribution cabinet cannot achieve the shock absorption effect, which can easily cause damage to the cabinet body and damage to the electrical components inside the high-voltage distribution cabinet, which may cause some unnecessary economic losses.

[0004] For example, a shock-absorbing high and low voltage distribution cabinet structure disclosed in Chinese patent CN214755001U includes a distribution cabinet, a shock-absorbing support column is provided on the bottom surface of the distribution cabinet, the bottom surface of the shock-absorbing support column is fixed to the top surface of the pad, the surface of the pad is provided with an inclined support plate, the top surface of the inclined support plate is provided with a connecting plate, the surface of the connecting plate is provided with a fastening screw, a rubber belt is provided between the surface of the inclined support plate and the top surface of the pad, a sleeve is provided on the bottom surface of the distribution cabinet, a reinforcing rib plate is provided on the outer wall of the sleeve, the reinforcing rib plate is fixed to the bottom surface of the distribution cabinet, and a support screw is inserted into the inside of the sleeve; the beneficial effect is: a sleeve is added to the bottom of the shock-absorbing high and low voltage distribution cabinet structure proposed by the utility model, the sleeve is stably fixed by the reinforcing rib plate, and a support screw is added inside the sleeve to pull the universal wheel, which drives the support screw to descend along the sleeve, and after the pad is suspended, it is convenient to promote the transfer of the distribution cabinet.

[0005] However, the shock-absorbing high and low voltage distribution cabinet structure lacks heat dissipation mechanisms, especially air cooling channels, to effectively dissipate heat inside the cabinet. When the weather is hot, the equipment and wiring in the distribution cabinet will be too hot, which will lead to insulation aging, and the phenomenon of burning internal equipment and distribution cabinets will occur from time to time, which can easily cause the circuit to burn out. In severe cases, it may even cause a fire, causing harm to people’s property and lives, and affecting the normal supply of electricity.
