Description

Technical Field

[0001] The utility model relates to the technical field of overhaul and maintenance safety, and in particular to an intelligent overhaul and maintenance safety device for a substation. Background Art

[0002] As a key equipment for power conversion and transmission, transformers play an important role in industry and power systems. In order to ensure its safe and reliable operation, regular maintenance and repair work is required. Usually, a safety fence needs to be built around the periphery of the outdoor transformer, and a safety gate is provided on the safety fence for construction workers to enter. In order to prevent unrelated personnel and animals from accidentally entering, it is necessary to lock the safety gate and the fence door frame. However, at present, only a padlock is installed on the outside between the safety gate and the fence door frame. If the construction workers want to enter the fence of the outdoor transformer, they need to open the padlock outside to enter. When the construction workers enter the fence of the outdoor transformer, there may be a long operation time. The construction workers only slightly close the safety door, and it is difficult to lock the padlock outside the fence from the inside of the fence, which makes it easy for the safety door to be opened, which makes it easy for unrelated personnel and animals nearby to mistakenly enter the construction site, affecting the safety of the construction workers in the fence.
