With the continuous growth of global power demand and the continuous progress of technology, the types of electrical equipment in substations are increasingly diversified, and the functions are more complex, which not only puts higher requirements on the design and construction of substations, but also brings new challenges to the installation and maintenance of electrical equipment.

[0003] The traditional electrical equipment installation method usually adopts bolt fastening or welding method to fix the equipment on the mounting seat. Although this method is reliable, it needs a lot of time and manpower to complete, and each electrical equipment installation needs to be bolted or welded one by one. Especially in large-scale substation construction and renovation projects, this inefficient installation process will significantly prolong the construction period. After the electrical equipment is fixed, if the position needs to be adjusted or the equipment needs to be replaced, the original fixing device must be removed, which not only increases the workload, but also may cause equipment damage. In addition, after the electrical equipment is installed outdoors, it is exposed to the open air for a long time, which is easily affected by factors such as direct sunlight and rain erosion, causing the equipment to age rapidly, reducing the service life, and increasing the maintenance cost.

[0004] Therefore, it is urgent to provide an installation and fixing structure that can quickly, safely and flexibly install electrical equipment and provide good protection. UTILITY MODEL CONTENTS

[0009] Further, a plurality of square soft pads are uniformly arranged in the mounting guide slot of the pressing plate.

[0010] Further, ventilation slots are formed on the bottom plate and the mounting guide slot of the pressing plate.

[0011] Further, a rubber pad is arranged on the inner side of the clamping plate.

[0012] Compared with the prior art, the device has the following technical effects: 1. The device can fix multiple electrical cabinets in a short time without using traditional fixing methods such as bolts or welding, greatly shortening the installation and disassembly time, improving the installation and maintenance efficiency, and providing effective sun-shading and rain-proof functions for the frame structure composed of the bottom plate, the fixed rod and the top plate, reducing the influence of direct sunlight and rain erosion on electrical equipment, prolonging the service life of the equipment, and reducing the maintenance cost.
