The primary-secondary integrated complete set of ring main unit integrates the power distribution, protection and control equipment on the primary side and the secondary side in a box body to achieve the complete power distribution of the power system. At the same time, the high-voltage incoming line cabinet and the low-voltage incoming line cabinet can be separated from the primary-secondary integrated ring main unit cabinet, which is convenient for maintenance and upgrading. The primary-secondary integrated complete set of ring main unit usually consists of a high-voltage incoming line cabinet, a high-voltage disconnector, a high-voltage load switch, a transformer, a low-voltage load switch, a protection device, a control device and a measuring device, etc. It can realize the distribution, regulation, protection and control of the power system, and improve the reliability and safety of the power system. The primary-secondary integrated complete set of ring main unit is usually used in urban power grids, industrial electricity, large buildings and other places, and is one of the indispensable power distribution equipment in the power system.

[0003] When the existing complete set of equipment for a primary-secondary integrated ring main unit pole-mounted transformer platform is installed on a telegraph pole by using a bracket, the telegraph pole is installed and fixed by opening mounting holes on the bracket and then using a hoop to hold the telegraph pole. Since the length dimension of the bracket is fixed, but the distances between telegraph poles are different, the mounting holes cannot accurately correspond to the telegraph poles, which is not conducive to the installation of the complete set of equipment for a primary-secondary integrated ring main unit pole-mounted transformer platform. In order to facilitate the installation of the complete set of equipment for a primary-secondary integrated ring main unit pole-mounted transformer platform, we propose the complete set of equipment for a primary-secondary integrated ring main unit pole-mounted transformer platform to solve the above problems.
