The oil-immersed transformer has a great influence on our production and life, so it is very important to choose a good transformer, so what are the key points for the selection of the oil-immersed transformer? Let's take a look together next.
This is the content list:
l Load properties of oil-immersed transformer
l Use environment of oil-immersed transformer
l Electricity load of oil-immersed transformer
1. When the oil-immersed transformer has a large number of primary or secondary loads, two or more transformers should be installed. When any one of the transformers is disconnected, the capacity of the remaining oil-immersed transformers can meet the requirements of electricity for primary and secondary loads. The primary and secondary loads of the transformer should be concentrated as much as possible, and should not be too scattered.
2. When the seasonal load capacity is large, a dedicated oil-immersed transformer should be installed. Such as the air-conditioning chiller load and heating electric heating load in large city buildings.
3. When the concentrated load is large, a dedicated oil-immersed transformer should be installed. Such as large heating equipment, large X-ray machine, electric arc furnace, etc.
Under normal medium conditions, oil-immersed transformer or dry-type transformer can be selected, such as oil-immersed transformer in industrial and mining enterprises, independent or attached substations in agriculture, independent substations in residential areas, etc.
1. The capacity of the oil-immersed transformer for power distribution should be integrated with the facility capacity of various electrical equipment to calculate the oil-immersed transformer load (generally excluding the fire load), and the apparent capacity after compensation is to select the oil-immersed transformer capacity and the basis of the number of units. Generally, the load rate of the transformer is about 85%. This method is relatively simple and can be used to estimate the capacity of the Oil-immersed transformer.
2. In GB/T17468-1998 "Guidelines for Selection of Power Transformers", it is recommended that the capacity selection of oil-immersed transformers for power distribution should be based on GB/T15164-94 "Oil-immersed transformer load guidelines" or GB/T17211-1998" Dry-type power transformer load guidelines" and calculate the load to determine the transformer capacity. The above two guidelines provide computer programs and normal cycle load diagrams to determine the capacity of the distribution oil-immersed transformer.
