Description

Technical Field

[0001] The utility model relates to the technical field of power cabinet protection, in particular to a power cabinet with strong impact resistance. Background Art

[0002] The power cabinet refers to a combination of electrical control cabinets that provide power for the normal operation of the entire machine. It includes contactors, frequency converters, high-voltage cabinets, transformers, etc. The power cabinet has the functions of providing power to electrical equipment, starting electrical equipment, and detecting whether the equipment is operating normally. Power cabinets can be divided into outdoor and indoor types. They can be divided into hanging and floor-standing types in terms of installation. They can be divided into power cabinets and power boxes in terms of size.

[0003] The protection of the power cabinet is weak. When an impact occurs, the power cabinet is easily damaged. The power cabinet also has poor shock absorption control, which affects the stability of the internal components of the power cabinet. In addition, the power cabinet outdoors will be hit by rain and needs to have a certain rain protection function. Therefore, a power cabinet with strong impact resistance is proposed to solve the above-mentioned problems. A power cabinet with strong impact resistance, which is disclosed in the prior art with a publication number of CN213816952U, supports the bottom plate and the cabinet body through leaf springs and provides good buffering and shock absorption effects. It is fixedly connected to the cabinet body through a support plate, and then the support plate is supported and reinforced by a reinforcing plate to improve the stability of the cabinet body. The water that enters the bearing seat can be discharged through the water leakage net, and the cabinet body can be assisted in heat dissipation through the heat dissipation fins. The top plate can not only block the rain, but also assist in heat conduction for heat dissipation, thereby improving the heat dissipation effect of the cabinet body. The left and right sides of the cabinet body are protected by the protective plate, and the main impact resistance and shock absorption are performed by the shock-absorbing and pressure-resistant spring parts. The shock-absorbing and pressure-resistant spring parts are longer and have a larger buffering distance. Auxiliary impact resistance is then performed by auxiliary pressure-resistant spring parts and rubber blocks. When the impact is too large, the protective plate will push the rubber block close to the cabinet body, and the auxiliary pressure-resistant spring parts will support and absorb shock, thereby improving the impact resistance. The power cabinet has strong impact resistance and good buffering and shock absorption effects.

[0004] In the prior art, the components that cannot resist impact are integrated with the cabinet body, which makes it difficult to disassemble and replace after effective protection, affecting practicality. At the same time, its heat dissipation capacity is poor, which is not conducive to use, so improvement is needed. Utility Model Content
