Description

Technical Field

[0001] The utility model relates to the technical field of box-type transformer maintenance devices, in particular to a box-type transformer maintenance device for photovoltaic power generation. Background Art

[0002] Box-type transformers (usually referred to as "box transformers") are traditional transformers designed in a box-type housing. They are small in size, light in weight, low in noise, low in loss, and high in reliability. They are widely used in residential areas, commercial centers, light power stations, airports, factories, mines, enterprises, hospitals, schools and other places. As a complete set of power distribution equipment, the basic principle of box-type transformers is to reasonably assemble the pressure starting system, armored wire, substation automatic system, DC point and corresponding technical equipment in the prescribed order, and install all components into the tempered box structure to form a specific transformer. Box-type transformers are widely used in power engineering construction, and their maintenance is also an important step to ensure the normal use of box-type transformers. The maintenance mainly involves regular inspections of box-type transformers by workers, component repairs and dust removal.

[0003] Traditional box transformers are fixedly installed in a small machine room. The space for workers to maintain the box transformers is relatively limited, which makes dust removal time-consuming and labor-intensive, and the maintenance work is inefficient. When maintaining the cable equipment on the top of the box transformer, it is inconvenient to observe due to the height, which also brings great difficulties to the workers. Therefore, we have launched a new box transformer maintenance device for photovoltaic power generation. Utility Model Content
