Hom twg yog qhov haum ntau, cov neeg ua kom haum lossis thyristor hloov mus hloov?
May 15, 2025| Kev sib piv cov yam ntxwv hluav taws xob: Tus neeg hu nkauj vs. Thyristor hloov
| Tus yam ntxwv | Hu tau (kho tshuab) | Thyristor (ruaj khov-xeev) | Kev tsom xam |
|---|---|---|---|
| Hloov txoj kev | Neeg kho tshuab hu | (Scr \/ triac) | Thyristors zam kev hnav neeg txhua yam tab sis xav kom cua sov dissipation; Cov neeg tiv toj ntsej muag cov teeb meem arcing. |
| Lus teb ceev | Slow (>250ms) | Fast (>20ms) | Cov tub ntxhais nyob ua ke siab dua (piv txwv li cov txhab nyiaj capacts); Cov neeg tiv toj rau lub xeev-lub xeev kev ncig. |
| Pes tsawg-hla kev hloov | Tsis tiav | Tiav tau | Thyristors Ntes Voltage Xoom-hla los txo cov hauv Inrrush tam sim no; Tus neeg hu ua kev sib tw arcing. |
| Lub zog poob \/ Tshav Kub | Tsawg (chev fais fab xwb) | Siab ({1-2 v conder txiav) | Thyristors yuav tsum tau heatsinks (tseem ceeb rau siab tam sim no); Hu rau cov cua sov kub ua kom pom kev sib cuag. |
| Temp. Yuav tsum tau | Tsawg ({-25 degree rau +60 degree) | Siab (yuav tsum nyob twj ywm<50°C) | Cov koj tsis txaus ntseeg ntawm Temps High; Tus neeg tiv toj zam lub tshav kub tab sis cov neeg tuaj yeem oxidize. |
| Lub neej | Long (>1m Cycles) | Luv (~ 100k mus) | Hu rau lub neej txwv los ntawm kev sib cuag hnav; Thyristors swb tsis tau vim muaj kev sib tshuam kev ntxhov siab \/ surges. |
| Tus nqi | Qis dua (ntaus + txij nkawm) | Siab dua (heatsink + tsav tsheb Circuit) | Thyristor Systems Yuav tsum tau ntsuas cov khoom siv; Cov neeg saib xyuas xav tau lub sijhawm sib tiv tauj |
Los ntawm cov lus sib piv saum toj no, ntau qhov kev txiav txim siab tuaj yeem pom:
1. Tus neeg sib cuag hloov nrawm yog qeeb, nrog kev poob qis, tsawg yuav tsum muaj rau qhov chaw kub thiab kub thiab tsis muaj peev txheej.
2. Tus Thyristor hloov ceev nrawm nrawm, muaj kev poob siab, siab yuav tsum muaj rau qhov chaw kub, thiab peev nyiaj siab.
Ob hom kev hloov no muaj lawv tus kheej zoo thiab qhov tsis zoo nyob hauv cov nqe lus ntawm daim ntawv thov.
Tam sim no, cov kev ua haujlwm nquag ntawm peb-theem khoom siv yog li hauv qab no, thiab raws li lawv cov yam ntxwv ua haujlwm, lawv tuaj yeem raug cais tawm hauv: 1. Hloov pauv nrawm
Lub chaw ua haujlwm khov kho: kev hloov pauv ntau ntawm cov kev ua haujlwm ua haujlwm tam sim no yog me me. Nov yog rooj plaub nyob rau hauv feem ntau kev lag luam thiab tsuas, kev lag luam hauv nroog lossis hauv nroog tsim kev lag luam. Cov kev lag luam no muaj qhov ruaj khov, thiab cov khoom siv hluav taws xob ua kom muaj zog kuj tseem ruaj khov. Yog li, cov cuab yeej them yog tsim nyog rau siv cov neeg ua haujlwm raws li lub capacitor hloov cov khoom siv vim tias cov thauj khoom ua haujlwm ruaj khov thiab tsis tas yuav muaj kev them nyiaj ceev.
Kev ua haujlwm-thauj khoom: Qhov kev hloov pauv ntau ntawm cov kev ua haujlwm ua haujlwm tam sim no yog qhov loj me, thiab cov chaw xa tawm sai. Kev lag luam ib txwm muaj kev lag luam suav nrog cov chaw tsim khoom lag luam rau cov khoom siv, steel mills, docks lossis cov roj hmab. Rau cov chaw muaj kev hloov kho sai sai, xws li chaw welding tshuab, cranes, cranes, cov khoom siv cranes kuj tsim cov khoom siv hluav taws xob ntau thaum ua haujlwm. Yog li, cov cuab yeej them nyiaj tau thov rau cov khoom siv yuav tsum yog tub luam tawm thyristor.
Surge Cov Teeb Meem Tam Sim No:
Yog tias cov tshuaj kho mob ntshiab yog saws, kev tawm tsam tam sim no thaum huab cua yuav siab npaum li 100 npaug ntawm cov rated tam sim no. Txawm li cas los xij, cov cuab yeej siv hluav taws xob cuam tshuam tam sim no, kom tsis txhob resonance hauv cov kab ke, feem ntau txuas ib qho inductor hauv cov npe ntawm lub capacitor. Qhov no tuaj yeem txo cov kev tawm tsam tam sim no thaum cov cuab yeej them nqi tau muab tso rau hauv kev ua haujlwm rau 6 txog 8 zaug qhov ntsuas uas muaj nyob tam sim no. Yog li ntawd, thaum capacitors tau txuas nrog inductors, qhov kev tawm tsam tam sim no tau txo qis.
Daim Ntawv Thov Thov
Nyiam cov neeg ua yeeb yamRau:
Kev ntseeg siab muaj zog (piv txwv li, kev tswj lub cev muaj zog).
Tsawg-zaus ua haujlwm lossis cov phiaj xwm kev txwv.
Xum koj cov thyristorsRau:
High-ceev hloov hloov (piv txwv li, cov khoom raug them rov qab zoo nkauj \/ TSC).
Precision Voj xoom hla kev siv (piv txwv li, cov khoom siv hauv tsev).
Hybrid Cov Ntsiab Lus:
Siv cov neeg muaj npe rau cov kab cig tseem ceeb + cov thyristors rau arc-dawb hloov (piv txwv li, ntse hloov mus hloov).
