[0002] With the development of power technology and the continuous improvement of power quality, the safety of transformers during maintenance has received more and more attention. A cooler bracket is provided on one side of the transformer box, and the cooler of the transformer is installed on the cooler bracket. The auxiliary device of the transformer (including oil pump, fan, motor and pipeline, etc., for heat dissipation and cooling medium delivery) is installed on the box next to the cooler. At present, some regions have required the installation of an inspection platform on the side of the auxiliary device of the transformer. The inspection platform and the transformer itself are an integral whole and can be used for a long time. The purpose is to prevent the staff from falling, thereby improving the safety of the staff. The power transformer of the prior art itself is not equipped with an inspection platform. The inspection platforms designed by people are temporary safety measures adopted when the transformer needs to be inspected after it is put into use. For example: Chinese patent CN202022778692.6 is named "a foldable inspection platform for transformers", CN202311625798.4 is named "a maintenance platform for inspecting high-altitude transformers" and CN201721468616.7 is named "a maintenance platform for large transformers". How to meet customer needs and provide transformer products with built-in maintenance platforms to improve safety performance is a technical problem that needs to be urgently solved in this field.
