Harmonics tshwm sim ntau thiab ntau zaus hauv peb lub neej niaj hnub.Feem ntau pom muaj kev sib haum xeeb feem ntau nyob hauv tsev kho mob, tsev kawm qib siab, tsoomfwv cov chaw, khw, chaw soj nstuam, kev lag luam hnyav, xov tooj cua, TV, tshaj tawm, kev lag luam khoom noj khoom haus, tsev so thiab twv txiaj yuam pov, kev lag luam automated, cov nroj tsuag kho dej ntau tshaj. Cov khoom siv sib xyaw ua ke xws li: hloov cov khoom siv hluav taws xob, vuam, Ups, qub zaus converter nrog thyristor fais fab converter tshuab, tsav tsav, converters nrog tswj rectifiers, DC maub los rau DC tsav, induction ncu.
Lub ntsiab qhov tshwm sim ntawm harmonics raws li hauv qab no:
1.Overheating thiab vibrations nrog kev laus ntxov ntxov ntawm txhua qhov chaw, nrog rau lub sij hawm luv luv thiab nruab nrab ntawm lub neej expectancy.
2. Ua txhaum ntawm cov khoom siv hluav taws xob hluav taws xob.
3.Kev puas tsuaj rau cov khoom siv hauv Circuit Court board.
4. Hluav taws xob lub cev muaj zog tshaj.
5.Premature aging capacitors thiab puas vim resonance.
6.Power factor txo.
7.Overload ntawm lub nruab nrab hlau.
8.Electromagnetic cuam tshuam.
9.Kev ntsuas yuam kev ntawm lub zog ntsuas.
10.MCCB thiab contactor cuam tshuam kev ua txhaum.
11.Kev hloov pauv tsis raug.
Active harmonic limyog cov khoom siv hluav taws xob zoo uas dynamically muab cov kev tswj xyuas tam sim no uas muaj tib lub amplitude raws li cov kev sib haum xeeb tam sim no, uas tau txhaj tshuaj tiv thaiv kev sib haum xeeb ntawm lub network.Qhov no yuav tshem tawm cov kev sib haum xeeb tam sim no hauv cov tshuab hluav taws xob.Yog li ntawd, tam sim no muab los ntawm lub hwj chim qhov chaw yuav nyob twj ywm sinusoidal raws li cov harmonics yuav tshem tawm ib leeg tawm thiab harmonic distortion yuav raug txo kom tsawg heev.
Cov lim dej nquagtuaj yeem ntsia tau rau txhua qhov chaw ntawm lub network thiab muaj ntau yam nta:
1. Tshem tawm tag nrho cov kev sib raug zoo tam sim no mus txog 50th kev txiav txim los ntawm cov khoom tsis-linear.
2.Compensate lub reactive hwj chim thiab kho lub hwj chim yam.
3.Compensate rau flicker tshwm sim los ntawm reactive hwj chim.
Noker Electricactive zog limtxais yuav cov thev naus laus zis peb qib siab tshaj plaws, nrog rau cov yam ntxwv ntawm qhov me me, lub zog loj ntom ntom, ruaj khov thiab txhim khu kev qha kev ua tau zoo, uas yog cov neeg siv khoom txaus siab. kev them nyiaj, kev sib haum xeeb ntawm 3 txog 50 harmonic, tuaj yeem ua kom zoo tshaj plaws ntawm koj daim phiaj zoo.
