Description

Technical Field

[0001] The utility model relates to the field of dry-type transformer maintenance tooling, in particular to a dry-type transformer module ladder. Background Art

[0002] When inspecting dry-type transformers, it is necessary to climb to a high place for inspection. However, due to the narrow space between the transformer body and the outer shell, and the corresponding connecting copper bars or copper tubes and cooling fans blocking the space, ordinary ladders cannot be used. For this reason, in the past, when inspecting transformers, people either climbed directly with bare hands or climbed with bare hands after setting up a wooden stool. However, no matter how they climbed, there was a possibility that the workers would scratch, slip, fall, or step on and damage the copper bars or copper tubes and other equipment, so it was not possible to inspect and maintain the transformer safely, efficiently, and conveniently.

[0003] The dry-type transformer is in a confined and narrow space. The ordinary ladders sold on the market cannot adapt to the use scenarios during dry-type transformer maintenance. Ordinary ladders are difficult to adapt to the height of the ladder. Ordinary ladders need to be constantly adjusted. When ordinary ladders are used for transportation, they are easy to touch other parts of the transformer and other electrical devices near the transformer. When ordinary ladders are used, they cannot avoid contact with the ground, affecting the operation of the dry-type transformer and the safety of the staff. Utility Model Content
