What is Dry Type Transformer?
The Dry type transformer is a machine which consists of windings which are attached to a core, and are kept in a tank which is sealed shut and then pressurized with air.Such equipments never use any insulating medium where the winding and cores can be plunged.
Type of Dry Type Transformer
Even though transformers are of various kinds, the dry type machine comes in two variants-
Cast Resin Dry Type Transformer ( CRT)
These devices are utilized in areas which have high degree of wetness. This is mostly because both the primary and secondary windings are enclosed in an epoxy resin. This in turn helps to a great deal since it prevents the body from getting affected or harmed with moisture. The reason why the entire the cast resin is so important is that it helps the machine in running in a glitch-free manner without causing any disruptions. This is the main reason why the transformer is non hygroscopic. Such equipments are accessible with different ratings varying from 25 KVA to 12,500 KVA. with insulation class of F (90°C Temp. Rise).
Such devices have certain advantages which are as follows-
Such machinery are made with the least amount of flammable elements as insulation windings. These(the windings) are fabricated using foil or strips in ceaseless layers. When we talk about high electric flux, the construction of such windings change. They are the created with disks, each of which are connected in series or parallel as per the given energy evaluation with respect to the level of electric flow. Being void free in nature, the insulation used on such goods is developed with the help of class H polyester resin. Both the cores are tied in a secure manner and are placed in a protective container which is vaccum tight. Guaranteeing you regarding their moisture resistance, such equipments come in 5 KVA to 30MVA with insulation grade F(155oC) and H(180oC). They have a protection level of around IP56. The numerous advantages of such goods are-
