Amorphous alloy material characteristics of amorphous alloy is a new type of magnetic properties of outstanding materials, using a rapid quench solidification process, its physical manifestations of metal atoms is disordered amorphous arrangement, it with the silicon crystal structure is completely different, more beneficial for magnetization and demagnetization. Typical amorphous alloy containing 80% iron, and other ingredients are boron and silicon.
One, the amorphous alloy iron core transformer.
( 1) phase five column transformer iron core are arranged in two rows of rectangular, two side columns through the zero flux, flux through the body, does not produce heat loss, so that the transformer can meet the requirements of low noise, low loss;
( 2) a high voltage coil are rectangular copper winding coil, when by chance when the short circuit occurs, can adapt to greater mechanical stress damage, the coil can not deform;
( 3) box body is made of cold rolled steel sheet sheet radiator, high and low pressure casing above with hail prevention, dust, rain cover, the lead no conductor is bare, available cable wiring, insulation protection;
( 4) transformer thermal cycle oil filled with silicone oil, the box sealed, within 20 years of free maintenance, and can adapt to high places.
In two, the amorphous alloy iron core transformer specifications
( 1) size: 30kVA～ 1600kVA, 6kV～ 10kV/0.4kV/0.22kV voltage, coupling groups labeled Y· yn0, D ·yn11;
( 2) the no-load loss, load loss, impedance voltage, main insulation shall meet the technical requirements of GB/T6451-1995.
In three, the amorphous alloy iron core transformer energy saving effect
Amorphous alloy iron core transformer, which has the advantages of low noise, low loss characteristics, no-load loss only conventional 1/5 products, and fully sealed maintenance-free, low operation cost
Amorphous alloy transformer main features and Applications
① the no-load loss compared with S7 respectively, S9 decreased by 75% and 70% type distribution transformer;
The amorphous transformer no-load input power factor is 0.35, that of silicon steel sheet core distribution transformer is more than 8 times;
The silicon steel sheet iron core distribution transformers iron loss varies with the voltage change square; whereas the amorphous variable loss does not change with the voltage;
④ SH10 type distribution transformer economic load rate is 20%, very suitable for rural low load rate of users; SH11 type distribution transformer economic load rate is 45%, suitable for city and high load rate of users.
Amorphous alloy transformer with small no-load loss and economic operation and load rate is relatively low, especially rural township, city residents living electricity, even during load rate reaches 50% ～80% into three shifts in the industrial and mining enterprises, choose the right capacity of the amorphous alloy transformer can still achieve the payback period of investment requirements. Therefore, in city and rural areas to promote the use of amorphous alloy transformer, can not only reduce the loss of the transformer, but also because of its good the energy-saving effect cause building power plant environmental benefits, in the construction of a resource-saving society today is of great realistic significance.
