Scb13-400kva dry type transformer operation reliability mainly depends on the design and manufacture of dry type transformer, structural materials, but also closely related to maintenance and maintenance, dry type transformer greatly promotes the continuous development of production and life dry type transformer is also in our daily life.
Scb13-400kva dry transformer is mainly composed of coated iron core, silicon steel plate and epoxy coil. Insulation tube is placed between high voltage coil and low voltage coil to increase electrical insulation. The coils are braced against looseness.
This structure is characterized by the coil surrounded by the core, the power of the single-phase SCB13-400kVA dry transformer is commonly used in the core type, to reduce the amount of iron. Scb13-400kva dry transformer core is used to form a magnetic circuit, in order to reduce eddy current loss, the core is made of thin silicon steel sheets interlaced. The surface of silicon steel sheet is coated with insulating paint and oxidized to form insulating layer.
Single-phase small power SCB13-400kVA dry transformer windings, multi-purpose high strength enameled wire winding system. High-power SCB13-400kVA dry transformer is mainly wound with flat copper wire or aluminum wire. Cylindrical winding is used when winding, and the low-voltage winding is close to the core for insulation. The high – voltage winding is cocentered on the low – voltage winding. Scb13-400kva dry type transformer according to the number of windings, can be divided into three categories.
(1) Single-coil SCB13-400kVA dry transformer has only one winding, also called autocoupled SCB13-400kVA dry transformer, as shown in Figure 11-9(1).
(2) The double-coil SCB13-400kVA dry transformer has two windings, as shown in Figure 11-9(2).
(3) multi-circle SCB13-400KVA dry transformer has more than two windings, commonly used with three circles SCB13-400KVA dry transformer,
Scb13-400kva dry transformer two windings in the higher the voltage is higher, the lower the voltage. The high voltage winding can be separated from the concentric winding according to the relative position of the high voltage winding and the low voltage winding. The concentric winding structure is simple and adopted.
