Dab tsi yog lub txee capacitor siv rau? Dab tsi yog lub luag haujlwm ntawm kev ntxiv capacitor txee? Kev siv lub tshuab capacitor

Feb 10, 2022

Tsawg voltage capacitor them nyiaj txee yog feem ntau siv nyob rau hauv tis system ntawm industrial thiab manufacturing factories. Feem ntau, qis-voltage capacitor them nyiaj txee yog tsim los ntawm lub hwj chim capacitor, reactor, ntes, Circuit Court breaker, fais fab tuag tsis siv neeg them nyiaj tswj ntaus ntawv, rho tawm hloov, thermal relay, disk ntsuas thiab lwm yam khoom. Tsawg voltage capacitor them nyiaj txee rau hauv lub zog hluav taws xob, feem ntau yog siv cov khoom siv hluav taws xob tsawg los ua lub luag haujlwm ntawm cov nyiaj siv hluav taws xob reactive, txhawm rau txhim kho lub zog, txhim kho lub zog zoo ib puag ncig. Lub luag haujlwm ntawm lub txee them nyiaj yog: tam sim no 90 degrees ua ntej ntawm qhov hluav taws xob, siv cov kab hluav taws xob sib txuas los txhim kho cov kab hluav taws xob, txo cov hluav taws xob tsis zoo. Raws li tus kws tshaj lij hluav taws xob yuav tsum tau kawm, lub kauj yog sib cais los ntawm kev khiav ncaj qha, thaum lub coil muab lub zog, muaj qhov tam sim no los tsim cov hlau nplaum, thaum lub zog raug txiav, lub kauj yuav tsim hluav taws xob. Nws zoo li muab lub zog rov qab. Nyob rau hauv lub cev muaj zog, koj muaj coils zoo li no, thiab koj ua alternating tam sim no 100 zaug ib ob. Lub zog siv hluav taws xob ntsuas tus nqi ntawm lub zog koj siv, uas yog siv thiab xa rov qab, uas yog lub zog reactive.

1. Capacitance them yog reactive hwj chim them los yog lub hwj chim yam them nyiaj. Cov khoom siv hluav taws xob hauv lub zog hluav taws xob yuav ua kom muaj zog inductive reactive nyob rau hauv cov txheej txheem ntawm kev siv, uas yuav ua rau kom txo tau lub peev xwm efficiency ntawm lub hwj chim mov.

2. Lub luag hauj lwm ntawm capacitor them nyiaj: lub parallel capacitor generates capacitor tam sim no los offset inductance tam sim no, thiab txo qhov li ntawd -hu ua reactive tam sim no uas tsis ua hauj lwm rau ib tug tej yam ntau yam, thiaj li tswj kom reactive zog tshuav nyob rau hauv lub hwj chim. qhov system.

3. Cov kev xaiv tshwj xeeb yuav tsum tau ua raws li lub peev xwm ntawm lub transformer xaiv, feem ntau ntawm cov nyiaj them rau lub transformer muaj peev xwm ntawm ib tug - thib peb.


Reactive zog yog dab tsi?

Reactive zog txhais tau hais tias nyob rau hauv ib tug inductive los yog capacitive AC Circuit Court, lub inductor (los yog capacitor) khaws lub zog ntawm AC lub hwj chim qhov chaw nyob rau hauv daim ntawv ntawm magnetic teb los yog hluav taws xob teb zog rau ib nrab ntawm lub sij hawm ntawm ib lub voj voog, thiab xa cov khoom sib nqus teb. los yog hluav taws xob teb hluav taws xob rov qab mus rau lub hwj chim qhov chaw rau lwm ib nrab ntawm lub voj voog. Nyob rau lub sijhawm no, lawv tsuas yog pauv lub zog nrog AC lub zog, thiab qhov tseeb tsis siv lub zog, tab sis tsuas yog pauv hluav taws xob thiab sib nqus hauv AC Circuit Court, thiab siv lub zog hluav taws xob los tsim thiab tswj cov hlau nplaum hauv cov khoom siv hluav taws xob. Qhov siab tshaj plaws ntawm lub zog pauv ntawm inductive lossis capacitive thiab AC lub zog yog hu ua reactive zog. Nws cov yam ntxwv loj tshaj plaws yog tias nws tsis ua haujlwm sab nraud, tab sis hloov mus rau lwm hom kev siv zog. Denoted los ntawm tsab ntawv cim Q, chav tsev yog Var los yog Kar.

Txhawm rau muab nws yooj yim, txhua yam khoom siv hluav taws xob nrog electromagnetic coils yuav tsum tau siv lub zog reactive los tsim ib qho chaw sib nqus. Kev qhia lej ntawm lub zog reactive yog Q=UIsin.

Qhib lub txee capacitor: thaum qhib, xyuas seb cov keyboards thiab Circuit Court breakers puas raug kaw ua ntej, tom qab ntawd kaw lub txee qhov rooj thiab ntswj lub qhov rooj qhov rooj hauv qhov chaw kaw, paub meej tias tsis muaj qhov yuam kev, thiab kaw cov riam hloov. Txoj kev nres yog: teem lub reactive fais fab maub los rau kev tuav haujlwm, siv phau ntawv nqes tus yuam sij kom tawm ntawm lub capacitor ib ntus, thiab tom qab ntawd rub rab riam qhib. Nws yog txwv tsis pub rub lub riam hloov nrog load los tiv thaiv arc xwm txheej. Qhov qis kawg ntawm Circuit Court breaker hauv lub txee capacitor tsis tuaj yeem txuas rau lwm lub hom phiaj. Lub txee capacitor yog txhawm rau txhim kho lub zog thiab tsis tuaj yeem thauj khoom. Capacitive them nyiaj txee siv capacitive reactance los them inductive reactance ntawm inductive load. Txo reactive tam sim no, txhim khu kab voltage, txo reactive poob, ua tiav cov nyhuv ntawm lub zog txuag. Saib xyuas tus naj npawb ntawm cov hloov pauv capacitors los ntawm kev siv lub ntsuas fais fab. Thaum lub hwj chim qhov tseem ceeb mus txog los yog ze rau 1, lub capacitor txee ua hauj lwm ib txwm. Lub capacitor them nyiaj txee yog tag nrho ntawm cov nyiaj them rov qab capacitors thiab cov contactors, uas yog hais tias, nws siv lub hauv paus ntsiab lus ntawm capacitor theem hloov los them cov nqi hluav taws xob reactive los ntawm cov khoom siv. Kev siv hluav taws xob tsis zoo lossis lub zog hluav taws xob tsis ua haujlwm, nws tuaj yeem qhib thiab kaw nrog tag nrho cov khoom siv hluav taws xob sib txuas ua haujlwm. Feem ntau, ntev npaum li koj tau xyuam xim xyuas lub capacitor txhua lub sij hawm tsis muaj qhov to lossis lub suab txawv txav thiab lwm yam kev txawv txav tuaj yeem ua tau.


Qhov kub ntawm lub hwj chim capacitor yuav tsum tsis txhob siab dhau. Yog hais tias qhov kub thiab txias ambient siab dhau lawm, lub tshav kub generated thaum lub capacitor ua hauj lwm tsis tau dispersed; Yog tias ib puag ncig tsawg dhau, cov txheej txheem kev ua haujlwm ntawm lub capacitor, kev ua haujlwm kub ntawm lub capacitor feem ntau yog 40 degree raws li qhov txwv siab. Qhov kub thiab txias yog qis dua nyob rau hauv feem ntau ntawm lub teb chaws, yog li cov chaw txias txias feem ntau tsis tsim nyog. Yog tias muaj qee qhov cua sov nyob ze ntawm lub capacitor, uas yuav ua rau chav tsev kub siab tshaj 40 degree, qhov cua thiab cua txias yuav tsum tau ntsuas, txwv tsis pub lub capacitor yuav tsum tau muab tshem tawm tam sim ntawd. Qhov ntsuas kub thiab qis qis ntawm lub capacitor yuav tsum tau txiav txim siab raws li hom thiab qhov xwm txheej ntawm tus capacitor mediator. Thaum lub hwj chim capacitor ua haujlwm, qhov kub ntawm nws qhov nruab nrab nruab nrab yuav tsum tsawg dua 65 degree, tsis tshaj 70 degree C, txwv tsis pub nws yuav ua rau thermal tawg, los yog ua rau lub plab bulge tshwm sim. Qhov kub ntawm lub plhaub capacitor yog nruab nrab ntawm qhov nruab nrab kub thiab qhov kub ntawm qhov nruab nrab, feem ntau 5060 degree, yuav tsum tsis pub tshaj 60 degree.
