Description

Technical Field

[0001] The utility model relates to the technical field of power equipment connection, in particular to a connection device for a non-magnetic equipment support frame. Background Art

[0002] In substations, booster stations, and collection stations, there is a magnetic field around reactors and other equipment during operation. If magnetic conductive materials such as steel are used, a closed loop will be formed to generate induced current, which will affect the durability of the equipment support frame and the safety of equipment operation. Therefore, the support frames of reactors and other equipment generally use non-magnetic conductive materials such as fiberglass pipes and aluminum alloys. Because fiberglass pipes, aluminum alloys, etc. do not have the same welding performance as metal steel, the existing technology generally uses a sleeve flange to achieve the connection between the fiberglass pipe and the base. The sleeve installation has high requirements on processing accuracy. If the flange size is too small, it will cause difficulty in installing the equipment support frame. If the flange size is too large, the gap between the two will be too large, resulting in an unreliable connection between the fiberglass pipe and the base and the equipment cannot be reliably grounded.
