Description

Technical Field

[0001] This application relates to the technical field of oil-immersed transformer clamps, specifically a clamp for an oil-immersed transformer that is resistant to short circuits. Background Technology

[0002] Oil-immersed transformers primarily use insulating oil as both a cooling and insulating medium, which is their core characteristic. Their application scenarios need to be explained, such as medium- and high-voltage, large-capacity transformers, commonly found in power systems, industrial sectors, and renewable energy projects. The mounting brackets for oil-immersed transformers are installed by manually tightening screws and nuts through four straight holes drilled at the four corners of the core. However, fixing the brackets and casing with screws and nuts allows the brackets and casing to easily connect to the ground, potentially causing a short circuit in the oil-immersed transformer. Utility Model Content
