Īss ievads of power transformer klasifikācija and raksturlielumi of power transformer
Ievads uz jauda transformatori Saskaņā to izmērs no transmisija jauda, jauda transformatori var būt sadalīts vairākās pakāpēs: 10}kVA and above for high power, 10}kVA to 0.5kVA for medium power, 0.5kVA to 25VA for low power, and below 25VA for micro power. It should be self-evident that the design of the power transformer is different for different transmitted power. Daži cilvēki tulkot the English name "Power Transformers" into "power transformeri" saskaņā to tā tā main funkcija of power transmission.
Brief Ievads of Power transformators
According to the size of the transmission power, the power transformer can be divided into several grades: above 10kVA is high power, 10kVA ~ 0.5kVA is medium power, 0.5kVA ~ 25VA is low power, and below 25VA is micro power. It should be self-evident that the design of the power transformer is different for different transmitted power. According to its main function of power transmission, someone translated the English name "powerTransformers" into "power transformer", which is still used in many documents. Is it called "power transformer" or "power transformer"? It is up to the authority on technical terminology to choose the decision.
Klasifikācija un raksturlielumi jauda transformatori
Klasifikācija of parasti lietots jauda transformatori var būt apkopots as sekojošs:
(1) Saskaņā to skaits of fāzes:
1) vienfāzes jauda transformators: izmantots priekš vienfāzes slodze un trīsfāzu jauda transformators grupa.
2) Trīsfāzu jauda transformators: lietots pacelšanai un nolaišanai spriegumam of trīsfāzu sistēmai.
(2) Saskaņā to dzesēšanas metode:
1) Sausais tips jauda transformators: rely on air konvekcija for dzesēšanai, parasti lietots mazjaudai jauda transformatori tādi as lokālais apgaismojums un elektroniskās shēmas.
2) Oil-immersed power transformer: rely on oil as the cooling medium, such as oil-immersed self-cooling, oil-immersed air-cooled, oil-immersed watercooled, forced oil circulation, etc.
(3) Saskaņā uz mērķi:
1) Power transformer: used for raising and lowering the voltage of the power transmission and distribution system.
2) instruments transformatori: šādi kā spriegums transformatori, strāva transformatori, lietoti mērīšanai instrumenti un relejs aizsardzība ierīces.
3) Tests transformators: It can ģenerēt augstspriegums un vadīšana augstspriegums tests ieslēgts elektriskais aprīkojums.
4) Speciālie transformatori: šādi as elektriskā krāsns transformatori;
(4) According to the winding form:
1) Dubultais tinums transformators: lietots pieslēgšanās divi spriegums līmeņi in the power sistēma.
2) Trīs tinumi transformators: parasti lietots in apakšstacijas in power sistēma zonas to savienojums trīs spriegums līmeņi.
3) Autotransformer: used to connect power systems of different voltages. It can also be used as an ordinary step-up or step-down transformer.
(5) According to the form of iron core:
1) Core transformer: Power transformer for high voltage.
2) Amorphous alloy transformer: Amorphous alloy core transformer is a new type of magnetically conductive material, and the no-load current drops by about 80[ percent ]. It is a distribution transformer with an ideal energy-saving effect at present, especially suitable for rural power grids and developing regions Where the load rate is low.
3) Shell-type transformers: special transformers for large currents, such as electric furnace transformers, welding transformers; or for electronic instruments and televisions.
