10KV class SH15 'SH16 series amorphous alloy oil immersed power transformer

Product/performance characteristics

Amorphous alloy transformer core magnetic material using amorphous alloy strip, its most prominent feature is the no-load current and no-load loss is very small.
The transformer iron core is made of amorphous alloy strip generally rolled into a three-phase five-column structure, so that not only the height of the transformer is lower than that of the three-phase three-column type, but also the two side yokes can flow in the high order harmonic or zero sequence component of the magnetic flux, effectively reducing the leakage voltage drop and improving the current quality.
Low voltage winding in addition to small capacity (100kVA below) using copper wire, generally use copper foil wound cylinder structure; The high voltage winding adopts multi-layer cylinder structure, the ampere-turns distribution of the winding is balanced, and the magnetic leakage is small. The high and low voltage coils are wound together with a wire tension device and are hot-pressed to enhance mechanical strength and resistance to short circuit impact.
The body adopts no hanging core structure, and adopts vacuum drying and vacuum oil injection technology. The oil tank is a fully sealed oil tank without oil storage tank.
Because the product adopts a fully sealed structure, the insulating oil and insulating medium do not contact with the air, and there is no need to change the oil under normal operation, which greatly reduces the maintenance cost of the transformer and extends the service life.
Through the calculation of annual power loss, annual power loss cost, and annual saving electricity, it is generally possible to recover its increased investment cost relative to the silicon steel sheet core transformer within three years.
