[0002] An on-load tap-changer is a switching device that provides a constant voltage to a transformer when the load changes. Its basic principle is to switch between taps in the transformer winding without interrupting the load current, thereby changing the number of turns in the winding, that is, the voltage ratio of the transformer, and ultimately achieving the purpose of voltage regulation. In today's power transmission and transformation industry, large transformers are widely installed with on-load tap-changers, which play an important role in ensuring the voltage quality of the system and users. Currently, developed countries have installed on-load tap-changers on most transformers with a capacity of 10MVA and above, and my country's power systems and users are also increasingly using on-load tap-changing transformers. The on-load tap-changer is its most critical and expensive component; general on-load tap-changers are installed in substations, and their installation site is generally equipped with a variety of related equipment. When inspecting and repairing the on-load tap-changer, due to the heavy casing, lifting equipment is required;

[0003] According to Chinese patent publication number CN 202785446 U, an on-load tap changer hanger is disclosed. In this application, the on-load tap changer is lifted by a hook, resulting in poor lifting stability and low safety. Utility Model Content
