Cikakken bayanin thyristor aikace-aikacen module

1. Aikace-aikace filayen na SCR modules

Ana amfani da wannan ƙirar mai hankali sosai a aikace-aikace kamar sarrafa zafin jiki, dimming, excitation, electroplating, electrolysis, caji da fitarwa, injin walda lantarki, arcs na plasma, samar da wutar lantarki, da sauransu, inda wutar lantarki ke buƙatar daidaitawa da canzawa, kamar haka. a matsayin masana’antu, sadarwa, da sojoji. Daban-daban na sarrafa wutar lantarki, kayan wuta, da sauransu kuma za a iya haɗa su zuwa kwamitin kula da ayyuka masu yawa ta hanyar tashar sarrafawa ta module don gane ayyuka kamar daidaitawa na yanzu, ƙarfin ƙarfin lantarki, farawa mai laushi, da sauransu, kuma yana iya gane kan halin yanzu, fiye da ƙarfin lantarki, fiye da zafin jiki, da daidaitawa. Ayyukan kariya.

2. Hanyar sarrafawa na thyristor module

Ta hanyar shigar da module iko dubawa wani daidaitacce irin ƙarfin lantarki ko halin yanzu sigina, da fitarwa ƙarfin lantarki na module za a iya smoothly daidaitacce ta daidaita girman siginar, don gane da aiwatar da module fitarwa ƙarfin lantarki daga 0V zuwa kowane batu ko duk conduction. .

Ana iya ɗaukar siginar wutar lantarki ko siginar yanzu daga kayan aikin sarrafawa daban-daban, fitarwar D/A na kwamfuta, potentiometer kai tsaye yana raba wutar lantarki daga wutar lantarki ta DC da sauran hanyoyin; siginar sarrafawa tana ɗaukar 0～5V, 0～10V, 4～20mA hanyoyin sarrafawa guda uku da aka saba amfani da su.

3. Sarrafa tashar jiragen ruwa da kuma kula da layin SCR module

Module kula da tasha dubawa yana da nau’i uku: 5-pin, 9-pin da 15-pin, wanda ya dace da 5-pin, 9-pin, da 15-pin controls bi da bi. Kayayyakin da ke amfani da siginonin wutar lantarki suna amfani da tashar jiragen ruwa mai fil biyar kawai, sauran kuma filayen fanko ne. Sigina na yanzu 9-pin shine shigar da siginar. Wayar jan ƙarfe na shingen kariya na waya mai sarrafawa yakamata a haɗa shi zuwa wayar ƙasa ta DC. Yi hankali kada ku haɗa da sauran fil. Tashoshin suna gajeriyar kewayawa don guje wa rashin aiki ko yuwuwar ƙona tsarin.

Akwai lambobi akan soket ɗin tashar tashar sarrafawa ta module da soket ɗin layin sarrafawa, da fatan za a rubuta ɗaya bayan ɗaya, kuma kada ku juya haɗin. Tashar jiragen ruwa guda shida da ke sama su ne ainihin tashar jiragen ruwa na module, kuma sauran tashoshin jiragen ruwa ne na musamman, waɗanda kawai ana amfani da su a cikin samfuran tare da ayyuka da yawa. Ragowar ƙafafu na yau da kullun masu sarrafa matsi ba su da komai.

4. Tebur kwatanta aikin kowane fil da launi na layin sarrafawa

Alamar fil ɗin aiki da launi mai dacewa 5-pin mai haɗawa 9-fiti mai haɗawa 15 mai haɗawa +12V5 (ja) 1 (ja) 1 (ja) GND4 (baƙi) 2 (baƙi) 2 (baƙi) GND13 (baƙi) 3 (baki da fari) 3 (baki da fari) CON10V2 (matsakaicin rawaya) 4 (matsakaicin rawaya) 4 (rawaya matsakaici) TESTE1 (orange) 5 (orange) 5 (orange) CON20mA 9 (launin ruwan kasa) 9 (launin ruwan kasa)

5. Haɗu da abubuwan da ake buƙata don aikin tsarin SCR

Dole ne a cika waɗannan sharuɗɗa a cikin amfani da tsarin:

(1) + 12V DC samar da wutar lantarki: samar da wutar lantarki mai aiki na da’irar sarrafawa na ciki na module.

① Wutar lantarki da ake buƙata: + 12V samar da wutar lantarki: 12 ± 0.5V, ƙarfin lantarki ya kasa da 20mv.

② Fitar da buƙatun na yanzu: samfuran tare da ƙarancin halin yanzu ƙasa da amperes 500: I + 12V> 0.5A, samfuran da ke da halin yanzu sama da 500 amperes: I + 12V> 1A.

(2) Siginar sarrafawa: 0～10V ko 4～20mA siginar sarrafawa, wanda ake amfani dashi don daidaita ƙarfin fitarwa. An haɗa madaidaicin sanda zuwa CON10V ko CON20mA, kuma an haɗa madaidaicin sanda zuwa GND1.

(3) Samar da wutar lantarki da kaya: Ƙimar wutar lantarki gabaɗaya ita ce grid, tare da ƙarfin lantarki da ke ƙasa da 460V ko na’ura mai ba da wutar lantarki, wanda aka haɗa zuwa tashar shigarwa na module; nauyin kayan aiki ne na lantarki, wanda aka haɗa zuwa tashar fitarwa na module.

6. Alakar da ke tsakanin kusurwar gudanarwa da kuma fitarwa na yanzu na module

Matsakaicin gudanarwa na module ɗin yana da alaƙa kai tsaye zuwa matsakaicin halin yanzu wanda tsarin zai iya fitarwa. Matsakaicin halin yanzu na module shine matsakaicin halin yanzu wanda za’a iya fitarwa a matsakaicin kusurwar gudanarwa. A ƙaramin kusurwar gudanarwa (matsayin ƙarfin fitarwa zuwa ƙarfin shigarwa yana da ƙanƙanta), ƙimar mafi girman fitarwa na yanzu yana da girma sosai, amma ingantaccen ƙimar na yanzu yana da ƙanƙanta (mitocin DC gabaɗaya suna nuna matsakaicin ƙimar, da mita AC. nunin sinusoidal halin yanzu, wanda ya fi ƙanƙanta fiye da ainihin ƙimar) , Amma ƙimar inganci na halin yanzu yana da girma sosai, kuma dumama na’urar semiconductor daidai yake da murabba’in ƙimar inganci, wanda zai haifar da ƙirar zafi ko ma konewa. Sabili da haka, ya kamata a zaɓi tsarin don yin aiki sama da 65% na matsakaicin kusurwar gudanarwa, kuma ƙarfin sarrafawa ya kamata ya kasance sama da 5V.

7. Hanyar zaɓi na SCR module ƙayyadaddun bayanai

Idan akai la’akari da cewa samfuran thyristor gabaɗaya ba su da igiyoyin sinusoidal ba, akwai matsala na kusurwar gudanarwa kuma nauyin halin yanzu yana da wasu sauye-sauye da abubuwan rashin zaman lafiya, kuma guntu na thyristor yana da ƙarancin juriya ga tasirin yanzu, don haka dole ne a zaɓi lokacin da ƙayyadaddun ƙirar halin yanzu. an zaba. Bar wani gefe. Ana iya ƙididdige hanyar zaɓin da aka ba da shawarar bisa ga dabara mai zuwa:

I> K × I load × U matsakaicin ∕U ainihin

K: factor aminci, ƙarfin juriya K = 1.5, nauyin inductive K = 2;

Iload: matsakaicin halin yanzu yana gudana ta wurin kaya; Uactual: ƙaramin ƙarfin lantarki akan kaya;

Umax: matsakaicin ƙarfin wutar lantarki da tsarin zai iya fitarwa; (Modul mai gyara sau uku shine sau 1.35 na shigar da wutar lantarki, tsarin gyara lokaci guda shine sau 0.9 na shigar da wutar lantarki, sauran ƙayyadaddun bayanai shine sau 1.0);

I: Ana buƙatar zaɓi mafi ƙarancin halin yanzu na module, kuma adadin halin yanzu na module ɗin dole ne ya fi wannan ƙimar.

Yanayin ɓarkewar zafi na ƙirar yana da alaƙa kai tsaye zuwa rayuwar sabis da ƙarfin ɗaukar nauyi na ɗan gajeren lokaci na samfurin. Ƙananan zafin jiki, mafi girma da fitarwa na yanzu na module. Saboda haka, dole ne a samar da kayan aikin radiator da fan. Ana ba da shawarar yin amfani da samfurori tare da kariya mai zafi. Idan akwai yanayin zubar da zafi mai sanyaya ruwa, an fi son zubar da zafi mai sanyi. Bayan ƙwaƙƙwaran ƙididdiga, mun ƙaddara ƙirar radiyo waɗanda samfuran samfuran daban-daban ya kamata a sanye su da su. Ana ba da shawarar yin amfani da radiators da magoya baya da suka dace da masana’anta. Lokacin da mai amfani ya shirya shi, zaɓi shi bisa ga ƙa’idodi masu zuwa:

1. Gudun iska na fanin kwararar axial ya kamata ya fi 6m / s;

2. Dole ne ya iya tabbatar da cewa yawan zafin jiki na farantin ƙasa mai sanyaya bai fi 80 ℃ ba lokacin da tsarin ke aiki kullum;

3. Lokacin da nauyin ƙirar ya kasance mai haske, za’a iya rage girman girman radiyo ko za’a iya ɗaukar sanyaya na halitta;

4. Lokacin da aka yi amfani da sanyaya yanayi, iska a kusa da radiyo na iya cimma convection da kuma ƙara yawan yankin na radiator daidai;

5. Duk sukurori don ɗaure module dole ne a ƙara ƙarfi, kuma dole ne a haɗa tashoshi masu crimping da ƙarfi don rage haɓakar zafi na biyu. Dole ne a yi amfani da Layer na maiko mai zafi ko kushin zafi mai girman girman farantin ƙasa tsakanin farantin ƙasan module da radiator. Domin cimma mafi kyawun tasirin zafi mai zafi.

8. Shigarwa da kuma kula da thyristor module

(1) Rufa wani Layer na thermally conductive silicone man shafawa a saman module’s zafi-Gudanar da farantin kasa da kuma saman na radiyo a ko’ina, sa’an nan gyara module a kan radiators da sukurori hudu. Kada ku ƙara ƙwanƙwasa sukurori a lokaci guda. A ko’ina, maimaita sau da yawa har sai ya tabbata, don haka farantin ƙasan module yana cikin kusanci da saman radiyo.

(2) Bayan haɗa radiator da fan bisa ga buƙatun, gyara su a tsaye zuwa inda ya dace na chassis.

(3) A daure wayar tagulla da kyau da tef ɗin zobe na tasha, zai fi dacewa a nutsar da ita a cikin tin, sannan a saka bututu mai hana zafi, sannan a dumama shi da iska mai zafi don ya ragu. Gyara ƙarshen ƙarshen akan na’urar lantarki kuma kula da kyakkyawar hulɗar matsi na jirgin sama. An haramta shi sosai don murƙushe wayar tagulla na kebul ɗin kai tsaye akan na’urar lantarki.

(4) Domin tsawaita rayuwar sabis na samfurin, ana bada shawara don kula da shi kowane watanni 3-4, maye gurbin man shafawa mai zafi, cire ƙurar ƙasa, da kuma ƙarfafa screws.

Kamfanin yana ba da shawarar samfuran samfuran: MTC thyristor module, MDC rectifier module, MFC module, da dai sauransu.
