AI Technical Summary

Technical Problem

The existing connection and fixing structure between the oil tank and the transformer body has problems such as low installation efficiency, cumbersome disassembly and assembly, insufficient fixing stability, susceptibility to external corrosion at the joint, and poor compatibility, resulting in low installation efficiency, high maintenance costs, poor sealing performance, and shortened equipment lifespan.

Method used

By installing a plug-in frame and annular sleeve on the top of the transformer body, combined with threaded rods, positioning rods, and semi-circular frames, the oil conservator body can be quickly and accurately connected and fixed. The cooperation of the annular sleeve and positioning rod ensures a stable connection between the oil conservator and the transformer body, and the semi-circular frame is used for protection.

Benefits of technology

It enables rapid and precise connection and disassembly of the oil tank and the transformer body, facilitating the installation and maintenance process, improving installation efficiency, reducing maintenance costs, enhancing fixation stability and sealing performance, and reducing the impact of external corrosion at the connection point.

Abstract

This invention discloses a transformer oil conservator connection and fixing device, including an oil conservator body installed on the top of the transformer body. A first flange is fixedly installed on the right side of the top of the transformer body through an opening. This invention relates to the field of transformer oil conservator technology. This transformer oil conservator connection and fixing device has plug-in frames installed on both the front and rear sides of the top of the transformer body, and plug-in bent frames installed on the surface of the oil conservator body using an annular sleeve, in conjunction with threaded rods and semi-circular frames. These structural features allow the plug-in bent frames to be directly inserted into the inner side of the plug-in frames after the annular sleeve is installed integrally on the surface of the oil conservator body, pushing the oil conservator body to move left and right on the top of the transformer body. This enables the second flange to quickly align with the first flange for easy fixing, which is undoubtedly more efficient and faster than manual handling and adjustment.
