cov Nyob tus nqi ntawm lub transformer yog cov kev cai tsim los ntawm cov chaw tsim tshuaj paus rau kev siv ntawm lub transformer ib txwm. Lub transformer ua haujlwm raws li tus nqi teev tseg kom ntseeg tau ua haujlwm ntev thiab ua haujlwm zoo. Nws cov qhab nia suav nrog cov hauv qab no:

1. Rated muaj peev xwm: Nws yog qhov guaranteed tus nqi ntawm cov zis muaj peev xwm ntawm lub transformer nyob rau hauv lub rated lub xeev. Chav tsev tau qhia hauv volt-ampere (VA), kilovolt-ampere (kVA) lossis megavolt-ampere (MVA). Tus nqi tsim ntawm qhov ntsuas muaj peev xwm ntawm thawj thiab theem nrab windings yog sib npaug.

2. Rated voltage: hais txog tus nqi lav ntawm lub davhlau ya nyob twg voltage thaum lub transformer tsis muaj load, thiab chav tsev yog qhia nyob rau hauv volts (V) thiab kilovolts (kV). Tshwj tsis yog tias tau teev tseg, qhov ntsuas hluav taws xob yog hais txog kab hluav taws xob.

3. Rated tam sim no: yog hais txog cov kab tam sim no suav los ntawm qhov ntsuas muaj peev xwm thiab ntsuas qhov ntsuas hluav taws xob, qhia hauv A (A).

4. Tsis muaj-load tam sim no: feem pua ​​​​ntawm cov excitation tam sim no mus rau qhov ntsuas tam sim no thaum lub transformer khiav ntawm tsis muaj load.

5. luv luv-circuit poob: lub active fais fab poob thaum winding ntawm ib sab yog luv luv-circuited thiab winding nyob rau sab nraud yog siv nrog voltage kom ob windings ncav cuag cov ntsuas tam sim no. Chav tsev qhia tawm hauv watts (W) lossis kilowatts (kW).

6. Tsis muaj-load poob: yog hais txog lub zog poob ntawm lub transformer thaum lub sij hawm tsis muaj load, qhia nyob rau hauv watts (W) los yog kilowatts (kW).

7. Short-circuit voltage: tseem hu ua impedance voltage, nws hais txog qhov feem pua ​​ntawm cov ntaub ntawv voltage thiab cov rated voltage thaum winding ntawm ib sab yog luv-circuited thiab lub winding ntawm lwm sab mus txog qhov ntsuas tam sim no.

8. Cov pab pawg sib txuas: Qhia txog hom kev sib txuas ntawm thawj thiab theem nrab windings thiab theem sib txawv ntawm cov kab voltages, qhia hauv moos.
