Closed type 36 dry-type transformer

　　A closed type 36 dry-type transformer refers to a dry-type transformer with a rated voltage of 36kV and a closed structure. Here is a detailed introduction:

　　Structure and Principle

　　Basic Structure: It is mainly composed of a core made of silicon steel sheets and windings. The core is usually made of high-quality cold-rolled grain-oriented silicon steel sheets, and the silicon steel sheets of the core adopt a 45-degree full-lap joint to reduce magnetic flux leakage. The windings are encapsulated in a closed shell, and are often insulated by epoxy resin vacuum casting.

　　Working Principle: Based on the principle of electromagnetic induction, when the high-voltage side is connected to the rated voltage, the current in the winding generates an alternating magnetic field in the core, and this magnetic field induces an electromotive force of the same frequency in the high and low voltage windings, thereby realizing the transformation of voltage.

　　Features

　　Good Sealing Performance: The closed structure can effectively isolate the contact between the windings and the outside air, preventing dust, moisture, and harmful gases from entering the transformer interior, which is beneficial to maintaining the insulation performance of the windings. It is especially suitable for harsh environments such as mines and industrial sites with more dust.

　　Safety and Fire Protection: As a dry-type transformer, it does not use insulating oil, so there is no risk of fire and explosion caused by oil leakage, which has good fire protection performance. It can be directly installed in places with high fire protection requirements such as residential areas, commercial centers, and airports.

　　Small Volume and Light Weight: Compared with oil-immersed transformers of the same capacity, dry-type transformers have a smaller volume and lighter weight, which is convenient for transportation and installation, and can also save installation space.

　　Low Maintenance Cost: The closed structure and the use of high-quality insulating materials reduce the possibility of component damage, and there is no need for regular oil replacement and other maintenance work, so the maintenance cost is low.

　　Application

　　Power Systems: It is suitable for voltage, power measurement, and relay protection in power systems with a rated frequency of 50Hz or 60Hz and a rated voltage of 35kV (close to 36kV).

　　Industrial and Mining Enterprises: It can provide power for various equipment in factories, mines, and other places, especially in some environments with explosion-proof requirements, such as coal mines, chemical plants, etc..

　　Urban Power Distribution: It is widely used in urban residential areas, commercial buildings, and other places to meet the power demand of users at the end of the power grid.
