Description

Energy storage cabinet dust-proof cotton selection method, device, equipment, medium and product Technical Field The application belongs to the technical field of energy storage equipment, and particularly relates to a method, a device, equipment, a medium and a product for selecting dust-proof cotton of an energy storage cabinet. Background As an important energy conditioning device, energy storage cabinets are often installed outdoors or in industrial environments, facing the risk of intrusion of foreign bodies such as dust, catkin, insects, etc. In order to ensure the insulation performance and operation safety of the internal electric elements, a dustproof cotton is usually installed at a ventilation air inlet of the energy storage cabinet for protection. However, in the prior art, the selection of the dustproof cotton specification mainly depends on the experience of engineers or a simple trial-and-error test method, and lacks scientific quantitative standards. On one hand, the mode selection is too conservative for pursuing high protection level, and dustproof cotton with too high aperture density or too large thickness is adopted, so that the air inlet resistance of the system is greatly increased, the actual working air quantity of the heat radiation fan is seriously attenuated, and further, the overheating of key components in the cabinet can be caused, even the overheat protection is triggered, the system is stopped, and the usability and the service life of the energy storage system are influenced. On the other hand, the selection is too aggressive to ensure sufficient heat dissipation air quantity, and dustproof cotton with too low aperture density or too thin thickness is adopted, so that the heat dissipation requirement is met in an initial state, but the protection capability is insufficient, and the foreign matters such as fine dust are easy to penetrate and accumulate in the equipment in a large amount, so that potential safety hazards of electrical short circuit or insulation reduction can be brought under long-term operation. More importantly, the empirical mode completely ignores the problem of performance attenuation of the dustproof cotton in the actual use process. As the service time increases, the ventilation resistance of the dust-proof cotton is continuously increased due to dust accumulation. A model selection scheme which seems to be qualified in an initial state can reduce the actual working air quantity to a dangerous level which cannot meet the heat dissipation safety requirement after a period of operation. Therefore, a method for selecting a model that can scientifically and quantitatively balance the heat dissipation requirement and the dust prevention requirement and can prospectively consider the performance attenuation of dust prevention cotton due to dust accumulation aging is needed in the prior art. Disclosure of Invention The embodiment of the application provides a method, a device, equipment, a medium and a product for selecting dust-proof cotton of an energy storage cabinet, which aim to solve the technical problems that the dust-proof cotton of the energy storage cabinet in the prior art depends on experience test mistake and cannot scientifically balance heat dissipation and dust prevention requirements, and particularly the heat dissipation safety risk is caused by performance attenuation of dust-proof cotton in the long-term use process is ignored.
