[0004] Opening vents on the cabinet body for ventilation and heat dissipation is a commonly used heat dissipation method for existing power distribution cabinets. When the temperature inside the cabinet is high, the hot air in the cabinet can be discharged through the vents, and the cold air outside the cabinet can also be discharged through the vents. The vent flows into the cabinet to achieve the purpose of heat dissipation, but when the cold air flows in, the dust in the environment outside the cabinet will also enter the cabinet with the air, and the flow and exchange of air will continue when the temperature inside the cabinet is normal, even Setting the filter screen cannot completely block the entry of dust, and the dust is easy to block the filter screen, which affects the effect of ventilation and heat dissipation. In this way, opening vents for ventilation and heat dissipation will make the dust in the cabinet more and more, and the dust will be larger. It is easy to cause short-circuit and other faults in electrical components, which has potential safety hazards and poor practicability

The invention discloses an internal circulation ventilated power distribution cabinet for power distribution automation, which belongs to the technical field of power distribution cabinets. When the temperature in the cabinet is high and heat dissipation is required, the hot air discharge pipe will be automatically turned on, so that the hot air in the cabinet can be discharged into the storage balloon shell, and the cold air in the storage balloon casing will be squeezed into the cabinet body, thereby The effect of ventilation and heat dissipation can be achieved through the way of air circulation, which can effectively prevent dust from accumulating in the cabinet due to ventilation and heat dissipation, which greatly improves the practicality and safety. , so that the hot air will not directly mix with the cold air in the storage ball shell, and the hot air discharged into the storage ball shell will be discharged into the cabinet again for ventilation and heat dissipation after a certain cooling, thus greatly improving The effect of ventilation and heat dissipation.
Description
technical field [0001] The invention relates to the technical field of power distribution cabinets, in particular to an internal circulation ventilation type power distribution cabinet for power distribution automation.
