Auxiliary working platform of substation transformer

Abstract

The invention discloses an auxiliary working platform of a substation transformer. The auxiliary working platform comprises a pit base, a transformer foundation arranged in the center of the pit base, a transformer arranged on the foundation, and a steel frame platform arranged above the pit base, wherein a groove body is arranged around the transformer; the groove body is provided with a cover plate mechanism; a lifting mechanism used for driving the cover plate mechanism is arranged below one end of the groove body; the lifting mechanism is arranged on a translation mechanism; and an L-shaped hoisting frame is movably arranged at the front end of the cover plate mechanism. When the transformer is overhauled, specific equipment or part can be hoisted and moved without other hoisting equipment to perform an auxiliary operation, so that potential safety hazard caused by movement of a large-scale hoisting apparatus in the transformer can be avoided; and therefore, the transformer can be overhauled and maintained by a staff more conveniently, and safety of the overhaul operation is also improved.

Description

technical field [0001] The invention relates to the technical field of transformer auxiliary equipment, in particular to a substation transformer auxiliary working platform. Background technique [0002] The substation is an important node of the power grid, which plays a role of linking the past and the future. The normal operation of the substation largely depends on the normal operation of the transformer. At present, the transformers in UHV and EHV substations are huge, and some meters and valves are located on the top of the transformers, which is extremely inconvenient for maintenance and emergency repairs. The pebbles are smooth and uneven, and cannot be placed firmly, posing safety hazards. In addition, pebbles are even more slippery in rainy days, which can easily cause people to fall. [0003] In order to facilitate the inspection and maintenance of the transformer, the staff wanted to set up a platform on site, but considering the complex surrounding conditions ...

Problems solved by technology

At present, the transformers in UHV and EHV substations are huge, and some meters and valves are located on the top of the transformers, which is extremely inconvenient for maintenance and emergency repairs. The pebbles are smooth and uneven, and cannot be placed firmly, posing a safety hazard

In addition, pebbles are even more slippery in rainy days, which can easily cause people to fall

[0003] In order to facilitate the inspection and maintenance of the transformer, the staff wanted to set up a platform on site, but considering the complex surrounding conditions and the high risk of the transformer, it is difficult to reserve a permanent inspection platform on the main transformer, so scaffolding needs to be erected on site for each inspection.

However, due to the transformer structure and other reasons, there are the following problems in scaffolding construction: 1. Below the construction point of disconnection and re-leading are transformer radiators, pipelines, and control systems. It may be different from batch to batch, or due to transformation, there are different dimensions and heat dissipation system structures, and it is impossible to make a set of universal quick scaffolding. If it is made separately according to each transformer, the equipment procurement cost will be doubled; 3. Using Although steel pipe / bamboo springboard scaffolding is low in cost and flexible in structure, it has defects such as limited bearing capacity, long construction period, and easy damage to the transformer heat dissipation system or bushing.

However, this invention does not take into account the complex circuit at the top of the transformer, and the upper circuit needs to be removed during use, which is troublesome
