Dry-type transformers are commonly used in electrical equipment, and are widely used in places such as local lighting, high-rise buildings, airports. Although the dry-type transformers are widely used, each type of specification can use all the environment, under normal circumstances, the use environments are different, the choice of dry-type transformers is not the same.
1.in the normal medium conditions, can choose oil-immersed transformers or dry-type transformers, such as industrial and mining enterprises, agricultural independent or attached to the substation, district independent substation.
2.in the multi-storey or high-rise main building, should use non-combustible or flame retardant transformer.
3.in the environment with dust or corrosive gas, seriously impact on the safe operation of the transformer site, should be selected closed or sealed type transformer.
4.without flammable oil, high and low power distribution devices and non-oil-immersed distribution transformers, can be set in a room, the transformer should be protected with IP2X shell, in order to safety.
In short, select the transformer must be based on the use of the environment, to ensure that the transformer life.
