Description

Technical Field

[0001] The utility model relates to the technical field of protective fences, in particular to a protective fence structure for a rectifier transformer unit. Background Art

[0002] Currently, in the electrolytic aluminum industry, large on-load tap-changing rectifier transformer units in rectifier substations typically have a rated capacity of 100-180MVA. These transformer units consist of a voltage-regulating transformer (referred to as the tap-changing transformer) and a rectifier transformer (referred to as the rectifier). These units occupy a large area and are tall (typically exceeding 5 meters).

[0003] Since large on-load tap-changing rectifier transformer units are static operating equipment, workers are prohibited from climbing the equipment when it is energized except for maintenance. In addition, there are few situations where workers need to work on top of the transformer. Therefore, there is usually no dedicated safety fence on the top of the transformer. There are only a few safety columns or simple railings, or the air duct on the top of the box cover is used as a safety hanging point for workers when working.

[0004] However, when the transformer equipment fails or needs maintenance, when the workers climb to the top of the transformer to deal with the fault, due to the various pipes, lines, protrusions or sealing structures on the top of the transformer, it is easy to trip the workers walking or performing maintenance work on top of the transformer. At this time, the above-mentioned method of not setting up protective fences or only welding simple railings will make it difficult to ensure the safety of the workers. The workers still face a great risk of falling from a height or stepping into empty space during maintenance work. Utility Model Content
