The power cabinet, that is, the power distribution cabinet, which is divided into power distribution cabinets, lighting distribution cabinets, and metering cabinets, is the final equipment of the power distribution system. The power distribution cabinet is a general term for the motor control center. The power distribution cabinet is used in the occasions where the load is relatively scattered and there are few circuits; the motor control center is used in the occasions where the load is concentrated and there are many circuits. They distribute the electric energy of a certain circuit of the upper-level power distribution equipment to the nearest load. This level of equipment shall provide protection, monitoring and control of the load. The power cabinet is a commonly used power infrastructure with a large number of power components inside, so the protection of the power cabinet is not important. At present, the power cabinets of many communication towers and signal towers are used outdoors. During the operation of the power cabinets, vibrations are likely to occur, and the power cabinets need to be limited and fixed. However, the existing power cabinets have poor shock absorption and stable operation. Low performance, such as the Chinese patent (application number: CN201621068134.8) a power cabinet base with a shock-absorbing effect. During this process, the rubber balls installed on the side walls of the power cabinet base on the left and right sides not only buffer the vibration of the power cabinet body, but also prevent the power cabinet base from causing damage to the power cabinet body. Since this solution only relies on the cooperation of multiple groups of shock-absorbing springs and rubber balls, its structure is too simple and the shock-absorbing effect is not good, so the shock-absorbing device of the power cabinet is improved.
