Thyristor mphamvu yang'anira: chithunzi mfundo ntchito ndi ntchito

Nkhani umu ndi momwe ntchito ya thyristor mphamvu yang'anira, lomwe chiwembu adzakhala anapereka pansipa

Tsiku ndi tsiku ndi zambiri zofunika kulamulira zipangizo mphamvu, monga cookers, soldering chitsulo, boilers ndi heaters, zoyendera - mota liwiro, etc. Thandizo akubwera yosavuta zofufuzafufuza wailesi kapangidwe - thyristor mphamvu yang'anira pa. Kudzisonkhanitsa chipangizo si yovuta, mwina woyamba chipangizo kunyumba zopangidwa kuti adzachita nsonga kutentha kulamulira ntchito soldering novice wailesi ankachita masewera. Tikumbukenso kuti yomalizidwa soldering siteshoni ndi ulamuliro kutentha, ndi zina zabwino kwambiri ngati mtengo kuposa chitsulo yosavuta soldering. Kuika osachepera zigawo limakupatsani kumanga yosavuta thyristor mphamvu yang'anira ndi mfundo Kulumikizana.

Kuti mudziwe, kulumikizidwa unsembe - njira ya kusonkhana ndi zigawo wailesi-pakompyuta popanda dera bolodi tinkawasindikiza ndi luso labwino, mofulumira kusonkhana zamakono cha kapangidwe sing'anga.

Mukhozanso kuyitanitsa amagetsi mlengi thyristor Mtsogoleri, ndipo anthu amene akufuna kumvetsa zonse nokha pansipa tchati ndipo anafotokoza ndi mfundo ya opaleshoni.

owongolera Mbali thyristor

Zodabwitsa ndizakuti, iyi ndi ntchito imodzi-gawo thyristor mphamvu yang'anira. Chotero chipangizo angagwiritsidwe ntchito kulamulira mphamvu kapena chiwerengero cha kusintha. Komabe, tiyenera kuzindikira mfundo ya ntchito thyristor, chifukwa ungatithandize kumvetsa mtundu wa katundu ndi bwino ntchito Mtsogoleri.

Kodi SCR?

Thyristor - molamulirika michenga yopangira zida zamagetsi chipangizo angathe kuchititsa ziliri pa njira imodzi. Mawu "kulamulira" ntchito Sichangozi, chifukwa ndi izo, mosiyana diode, amene lilinso panopa ku mtengo umodzi wokha, mukhoza kusankha nthawi imene thyristor akuyamba kuchita panopa. The thyristor ali malo atatu:

• Anode.
• Cathode.
• Chipata elekitirodi.

Kuti panopa anayamba kuyenda kupyolera thyristor, ndipo zinthu izi ayenera kukwaniritsa: katunduyo ayenera kukhala ndi unyolo mu mavuto, ulamuliro elekitirodi kuti aziwapatsa likukulira zimachitika. Mosiyana transistor, thyristor ulamuliro sikutanthauza posungira wa ulamuliro chizindikiro. Mu nuance izi si kutha: thyristor akhoza kutseka yekha kumamusokoneza ziliri pa dera, kapena kupanga n'zosiyana voteji anode - cathode. Izi zikutanthauza kuti kugwiritsa ntchito thyristors mu DC ndi zenizeni kwambiri ndipo nthawi zambiri mopanda nzeru, koma AC madera Mwachitsanzo mu chipangizo monga thyristor mphamvu yang'anira dera alembedwera njira yakuti kuonetsetsa zinthu kutsekedwa lapansi. Aliyense wa hafu ya mafunde adzakhala kutseka thyristor kake.

Inu mwina sangazindikire zonse? Musadandaule - adzakhala anafotokoza ndondomeko ya ntchito chipangizo yotsirizidwa.

owongolera Mbali thyristor

Mu Madera ena mosavuta ntchito thyristor mphamvu yang'anira? Chiwembu amalola chabwino kusintha mphamvu ya zipangizo Kutentha, ndiye ntchito pa katundu resistive. Pamene ntchito ndi katundu kwambiri inductive thyristors mwina si kutseka, zomwe zikhoza kuwonongeka kwa mankhwala.

Kodi n'zotheka kusintha liwiro injini?

Ine ndikuganiza owerenga ambiri aona kapena ntchito kubowola, ngodya chopukusira, amene ambiri amatchedwa "Bulgarians" ndi zipangizo zina mphamvu. Inu mwina mwaona kuti chiwerengero cha kusintha zimadalira mmene inu tilimbikire chipangizo batani-choyambitsa. Pano mbali iyi zoterezi Integrated thyristor mphamvu yang'anira (chiwembu chili m'munsimu), kudzera zomwe kusintha chiwerengero cha kusintha.

Samalani! Thyristor simungathe kusintha Motors liwiro kupatsidwa ulemu. Choncho, wokhometsa voteji kusintha mu injini okonzeka ndi unit burashi.

Galimoto thyristor mphamvu yang'anira pa thyristors limodzi kapena awiri

Chitsanzo chiwembu kusonkhanitsa thyristor mphamvu ndi manja awo zikusonyezedwa chithunzi pansipa.

The linanena bungwe voteji ku dera lino la volts 15 215 zinachitikira thyristors anati wokwera pa limalephera kutentha, mphamvu ndi 1 kW. Njira lophimba ndi kuwala dimmer unapangidwa chotero chiwembu.

Ngati safuna mokwanira voteji malamulo ndi kupeza linanena bungwe mokwanira kuchokera volts 110 mpaka 220, ntchito chithunzi ichi izo zikusonyeza theka-yoweyula thyristor mphamvu yang'anira pa.

Kodi ntchito?

Information pansipa ndi chomveka madera ambiri. Letter mayina adzatengedwa monga woyamba chiwembu thyristor Mtsogoleri

Thyristor mphamvu yang'anira, mfundo zomwe zachokera gawo kulamulira kusintha mtengo voteji ndi mphamvu. Mfundo imeneyi kwagona kuti zinthu zachilendo katundu pa alternating panopa ku zopezera banja, amene zimasiyanasiyana sinusoidally. Pamwamba chikunena za mfundo opaleshoni ya thyristor, izo zinanenedwa kuti aliyense chipangizo ntchito mu njira imodzi, kuti imayendetsedwa ndi ake theka funde la yoweyula sine. Kodi zikutanthauza chiyani?

Ngati adzakhala m'munsi chifukwa voteji a (mtengo wogwira, amene "afika" katundu) ndi zosakwana maukonde kudzera thyristor nthawi polumikiza katundu mu kamphindi bwino chimatanthauza, RMS voteji phindu. chodabwitsa Izi zikufotokozeredwa mu Zithunzi lapansi.

M'dera shaded - ichi ndi dera mavuto amene anaonekera pansi pa katundu. Kalata "ndi" pa olamulira yopingasa amatanthauza kutsegula kwa thyristor lapansi. Pamene zabwino theka-yoweyula mapeto ndi kuyamba nthawi ndi zoipa theka-yoweyula, mmodzi wa thyristors chatsekedwa, ndipo nthawi yomweyo chikuyamba ndi thyristor chachiwiri.

Tiyeni kumvetsetsa mmene ntchito chimodzimodzi thyristor wathu mphamvu yang'anira

chiwembu loyamba

Amatchula pasadakhale kuti mawu akuti "zabwino" ndipo "zoipa" ndi ntchito "woyamba" ndi "chachiwiri" (halfwave).

Choncho, pamene chiwembu wathu zimatengera zotsatira zoyambirira-yoweyula, anayamba cholusa mphamvu C1 ndi C2. Mlingo wa woyang'anira okha ndi potentiometer R5. yogwira amafotokozera ndi variable ndi ntchito kukonza ndi voteji linanena bungwe. Pamene capacitor C1 limapezeka kofunika kutsegula dynistor VS3 voteji dynistor atsegula, panopa umayenda therethrough, kudzera lofunyululalo thyristor VS1. Mphindi cha kuwonongedwa dynistor ndi mfundo "ndi" mu Zithunzi zokambidwa pa gawo yapita kwa nkhani ino. Pamene voteji umadutsa ziro ndi dera ndi pansi wachiwiri theka-yoweyula, ndi thyristor VS1 ndi chatsekedwa ndi ndondomeko akubwerezedwa kachiwiri, kokha kwa dynistor wachiwiri, thyristor ndi condenser. Resistors R3 ndi R3 ntchito kulamulira malire panopa, ndipo R1 ndi R2 - chifukwa olimba dera matenthedwe.

Mfundo ntchito ndi ofanana chiwembu chachiwiri, koma icho chimapita okha kasamalidwe mmodzi wa hafu ya mafunde a alternating voteji. Tsopano, podziwa mfundo ndi chiwembu, mukhoza kusonkhana kapena kukonza thyristor mphamvu ndi manja awo.

Ntchito yang'anira mu nyumba ndi chitetezo

Sitingathe kunena kuti zolinga zawo sasamalira galvanic kudzipatula kwa mains, kotero pali chiopsezo cha mantha magetsi. Izi zikutanthauza kuti ayenera asakhudze manja a ulamuliro wovuta. Muyenera kugwiritsa ntchito nkhani zokhazi. M'pofunika kupanga dongosolo la chipangizo chanu kuti n'kotheka inu chobisa mu chipangizo ankalamulira, kupeza mpando kanthu mu nyumba ya. Ngati chipangizo kulamulidwa ndi yosasuntha, ndiye ambiri n'zomveka kulumikiza izo kudzera lophimba ndi kulamulira kuwala kuwala. njira pang'ono kuteteza ku mantha magetsi, adzachotsa kufunika kupeza nyumba yabwino, liri ndi maonekedwe okongola ndiponso chopangidwa njira mafakitale.
