Thyristor jaangooyaha awood: jaantus ah mabda 'hawlgalka iyo codsiga

Maqaalkani wuxuu sharxayaa sida ay ku shaqeeyaan jaangooyaha awood thyristor ah, taas oo nidaamka lagu hoos ku siin doonaa

In nolol maalmeedka waxa aad inta badan waxaa lagama maarmaan ah in la xakameeyo qalabka xoog, sida makiinadaha, birta, kabida, kululeeyaha iyo kululeeyayaasha, gaadiidka - xawaaraha baabuurta, iwm Caawimaaddaydu waxay ka timaadaa radio hiwaayadda fudud design - thyristor jaangooyaha awood on. Urursada qalab noocan oo kale ah ma aha wax adag, waxaa laga yaabaa inay noqdaan aalad ugu horeysay ee guriga-dhigay in ku samayn doonaa, kabida heerkulka tip function gacanta ku laylis radio hiwaayadda. Waa in la ogaadaa in saldhigga kabida dhammeeyayna kontoroolka heerkulka, iyo qaababka kale ee fiican wax badan uu ka qaalisan yahay birta, kabida fudud yihiin. set ugu yar ee qaybaha kuu ogolaanayaa inaad si ay u dhisaan fudud jaangooyaha awood thyristor inay dhibcood taararka ah.

Wixii macluumaad ah, taaba rakibo - hab ka mid ah ururinayo ah qaybaha radio-elektaroonik ah oo aan isticmaalka guddiga circuit ku daabacan, iyo xirfadaha wanaagsan, uu si deg deg ah kulminhaynin qalabka elektarooniga ah ee kakanaanta dhexdhexaad ah.

Waxa kale oo aad ka dalban kartaa xakamaysada ah naqshadeeye thyristor elektarooniga ah, iyo kuwa doonaya in ay fahmaan oo dhan naftaada by, hoos ku yahay jaantuska iyo sharaxay by mabda'a hawlgalka.

nidaamiyo thyristor Baaxadda

Waana mid ka, taasi waa jaangooyaha awood thyristor-hal waji. qalab noocan oo kale ah waxaa loo isticmaali karaa in ay gacanta xoogga ama tirada Kacdoonkii. Si kastaba ha ahaatee, waa in marka hore la fahmo mabda'a of hawlgalka thyristor ah, maxaa yeelay waxa ay noo oggolaanaysaa in aan fahamsanahay nooca load fiican in la isticmaalo xakamaysada ah.

Sidee SCR?

Thyristor - aalad gacanta Semiconductor awood u qabanayo ee hadda ka jirta hal jiho. Erayga "gacanta" waxaa loo isticmaalaa shil jirin, sababtoo ah waxaa la, in la barbardhigo diode ah, kaas oo sidoo kale xanbaarsan yahay hadda in mid ka mid ah cadcad oo kaliya, waxaad dooran kartaa waqti marka thyristor bilaabo si ay u qabtaan hadda. thyristor wuxuu leeyahay seddex boosteejada:

• Anode.
• Cathode.
• koronto The iridda.

Si hadda bilaabeen inay qulo thyristor ah, shuruudaha soo socda waa in la buuxiyaa: shayga waa in ay silsilad in xiisad, koronto gacanta loogu deeqayo wadnaha go'aysa. Si ka duwan transistor, gacanta thyristor uma baahna haynta of signal gacanta. In midka this ma joogsan: thyristor waa la xiri karaa oo keliya kalagoynta hadda ka jirta Bannaanka, ama sameynta anode a danab dambe - cathode. Taas macnaheedu waa in isticmaalka thyristors in DC waa mid aad u gaar ah oo inta badan unwisely, laakiin wareeggeedii AC, tusaale ahaan qalab sida jaangooyaha thyristor xoog ah sida, circuit ay u dhisan tahay hab in la hubiyo shuruudaha xiritaanka a. Mid kasta oo ka mid ah nus-hirarka saari doonaa thyristor u dhigma.

laga yaabaa in aad wax kasayn korkooda wax walba? Ha ka quusanina - hadda si faahfaahsan lagu tilmaami doonaa habka of shaqeeya qalab dhamaystirtay.

nidaamiyo thyristor Baaxadda

In wareeggeedii qaar ka mid ah si wax ku ool ah u isticmaali jaangooyaha thyristor xoog ah? Nidaamku wuxuu ogolaanayaa wanaagsan qabsato xoogga qalabka kuleylka, in uu yahay, inay ka shaqeeyaan on load a resistive. Marka la xamuulka aadka u yeelista shaqeeya thyristors laga yaabaa in si fudud oo aan la xiro, taas oo keeni kartaa dhaawac soo saaraha.

Ma suurogalbaa in la qabsato xawaaraha engine ah?

Waxaan qabaa akhristayaasha badan oo u arkay ama loo isticmaalo layliga, Furimaha Dagaalka xagal, taas oo caan ku gudbiyo sida "Bulgarians", iyo qalab awood kale. Waxaa laga yaabaa in aad dareentay in tirada kacdoonkii ku xiran tahay sida aad uga aad riixdid batoonka qalab-keebka. Halkan element this jaangooyaha awood thyristor isku dhafan oo kaliya sida (nidaamka hoos ayaa lagu muujiyey), via kaas oo isbedelka ku dhacay tirada Kacdoonkii.

Waa inaad taxadar! Thyristor ma beddeli karaan matoorrada induction xawaaraha. Sayidka, danab ururiyaha la hagaajiyo in matoorada qalabaysan unit burushka.

Wadista jaangooyaha awood thyristor on hal iyo laba thyristors

nidaamka caadiga ah si ay u ururiyaan xoog thyristor gacmahoodii lagu muujiyay shaxanka hoose.

danab The saarka ka circuit this ee 15 ilaa 215 volts in ay dhacdo thyristors ayaa sheegay in Jaha on saxanka kulaylka, xoog ku saabsan yahay 1 kw. Way ku biiro iftiinkiis gaabiyo laga sameeyey nidaamka noocan oo kale ah.

Haddii aadan u baahnayn sharciyeynta danab buuxa iyo wax soo saarka ku filan ka 110 si ay u 220 volts hesho, isticmaali jaantuska in ay muujinaysaa kala bar-ruxruxo jaangooyaha awood thyristor on a.

Sidee u shaqeeyaan?

Macluumaadka hoos ku qeexan ansax tahay muddo wareeggeedii ugu. Letter tilmaamood ayaa laga qaadi doonaa sida uu u dirato nidaamka ugu horeysay thyristor ah

jaangooyaha awood Thyristor, mabda'a ah kaas oo ku salaysan gacanta wajiga isbedel qiimaha danab iyo xoog. Mabda 'Tani been in xaqiiqda ah in xaaladaha caadiga ah load ku on talantaalli ka network guriga, taas oo sinusoidally kala duwan ee hadda ah. Kor ku sharaxaad ka mid ah mabda 'hawlgalka ee thyristor ah, waxaa la sheegay in qalab kasta oo ka shaqeeya in hal jiho, oo loo maamulay in ay bar-ruxruxo ee la ruxruxo Culumida Soomaaliyeed. Maxay ka dhigan tahay?

Haddii ay noqon doontaa hoose sababta oo ah danab ee (qiimaha wax ku ool ah, oo "helo" load) waa in ka yar shabakadda via thyristor mudo xira load a daqiiqad si wanaagsan u qeexan, RMS qiimaha danab. Tani waxay ifafaale waxaa lagu muujiyey garaafka.

Meesha hadhka - taasi waa meesha xiisadda ayaa u muuqday hoos load. xarafka "a" on dhidibka siman tusinaysaa furitaanka thyristor ah. Marka dhamaadka qeybtii ruxruxo wanaagsan oo uu bilaabo xilliga la bar-ruxruxo xun, mid ka mid ah thyristors xiran yahay, iyo waqti isku mid ah ka furmay thyristor labaad.

Aan u fahmaan sida ay u shaqayso si sax ah our jaangooyaha awood thyristor

nidaamka ugu horeysay

Farayaan ka hor in ereyada "positive" iyo "negative" in la isticmaalo "marka hore" iyo "labaad" (halfwave).

Sidaas, marka nidaamka dhaqan marka hore bar-ruxruxo, bilaabaan ku amraya C1 awoodda iyo C2. Heerka la'aan waxaa xadiday potentiometer R5. element firfircoon waa variable, oo ay u isticmaalan in dhigay by danab wax soo saarka. Marka C1 capacitor u muuqataa lagama maarmaanka u ah furitaanka dynistor dynistor danab VS3 furmay, hadda socodka therethrough, iyada oo loo marayo taas oo VS1 thyristor furan. xaadirka ah ee dynistor burburka waa barta "a" ee garaafka lagu soo bandhigay qaybta hore ee qodobkan. Marka danab ku maraa eber iyo circuit ka yar yahay badhkiis la ruxruxo labaad, VS1 thyristor waa xiran yihiin iyo habka la mar kale soo noqnoqda, oo kaliya dynistor labaad, thyristor iyo condenser. Resistors R3 iyo R3 waxaa loo isticmaalaa si loo xakameeyo xad hadda, iyo R1 iyo Red2 - waayo, circuit xasilinta kaamerada.

Mabda'a hawlgalka ay la mid tahay nidaamka labaad, laakiin waxa ay u dhaco oo kaliya in ay maamulka ka mid ah bar-hirarka danab talantaalli ah. Haddaba, isagoo garanaya mabda'a iyo nidaamka, ayaan idinka soo shirin karo ama lagu dhiso awooda thyristor la gacmahoodu sameeyeen.

Isticmaalka jaangooyaha ah ee guriga iyo ammaanka

Waxaan ma dhihi karo, in nidaamka this ma bixiso go'doomin galvanic ka dhaxe ka, sidaa darteed waxaa jirta khatar ah in koronto. Tani waxay ka dhigan tahay in aanad taaban gacmaha gacanta safar ah. Waa inaad isticmaashaa kiis go'doonsan. Waa lagama maarmaan in la qorsheeyo qaab dhismeedka of qalab aad si mar kasta oo suurto gal ah inaad ku qarin kari weyday in qalab gacanta, aad u hesho kursiga madhan ee guryaha. Haddii qalabka gacanta ku waa taagan, ka dibna guud ahaan waxa macno in ay ku xirmaan via ku biiro si loo xakameeyo dhalaalka iftiinka. xal Tani waxay qayb ka badbaadiyaan shoog koronto, la baabi'iyo doonaa baahida loo qabo in la helo guryo ku habboon, waxa ay leedahay muuqaalka soo jiidasho iyo habka warshadaha macmalay.
