Lub hauv paus tseem ceeb hauv kev tsim tshwj xeeb ntawm kev siv lub tshuab welding yog kev hloov kho ntawm kev khiav hauj lwm tam sim no. Cov cuab yeej tsim khoom nqa tawm qhov no los ntawm shunting siv cov zawm caj dab ntawm ntau hom, hloov cov sib nqus flux lossis sib nqus shunting, siv lub tshuab ua kom zoo nkauj ntawm cov pob txha caj dab thiab cov ntxig rov qab thiab cov rheostats. Qhov tsis zoo ntawm qhov kev kho teeb meem no nyob rau saum npoo: cov nyom ntawm cov qauv, qhov loj heev ntawm cov resistances, lawv cov cua sov siab, tsis yooj yim thaum hloov.
Tsim nyog
- - transistors ntawm P416, GT308 hom;
- - kuj tsis paub meej resistor SP-2;
- - MLT resistors;
- - capacitors MBT lossis MBM 400 V
Cov Lus Qhia
Kauj ruam 1
Ua rau theem nrab winding thaum winding vuam transformer. Hloov tam sim no los ntawm kev hloov tus naj npawb ntawm lem. Qhov no yog qhov kev xaiv zoo tshaj plaws. Tab sis hom no tuaj yeem siv los kho qhov tam sim no xwb; nws tsis yog siv los kho nws dhau ntawm ntau qhov. Nws tsim nyog hais tias hom no tau cuam tshuam nrog qee yam teeb meem. Ua ntej txhua yam, vim qhov tseeb tias qhov tam sim no tseem ceeb dhau los ntawm cov cuab yeej tswj kev tswj hwm, uas ua rau nws txoj kev quab yuam ntau, thiab rau theem nrab Circuit Court nws tsis muaj peev xwm xaiv cov kev hloov khoom muaj zog uas yuav tiv taus tam sim no mus txog 200 A. 5 zaug tsis muaj zog.
Kauj ruam 2
Sib sau ua ke ntawm thyristor tus tswj xyuas. Lub hauv paus pib muaj, nws yooj yim rau kev khiav lag luam, tsis tas yuav tsum tau teeb tsa thiab tau ua pov thawj nws tus kheej hauv txoj kev ua tiav. Kev tswj lub zog hluav taws xob yog nqa los ntawm kev hloov kho ntu I-th winding ntawm vuam hloov khoom siv rau lub sijhawm ib ntus ntawm txhua lub sijhawm ib nrab ntawm qhov tam sim no. Hauv qhov no, tus nqi nruab nrab tam sim no txo qis.
Kauj ruam 3
Txuas lub ntsiab tseem ceeb ntawm tus neeg tswj hwm (thyristors) hauv kev sib txig thiab rov qab sib txig rau ib leeg. Lawv yuav hloov qhib nrog pulses tam sim no, uas tau tsim los ntawm transistors VT1, VT2. Thaum fais fab tuag thov rau lub chaw tswj, ob lub thyristors raug kaw, lub tshuab hluav taws xob C1 thiab C2 pib them los ntawm kev tsis sib xws resistor R7. Thaum ib qho ntawm lawv nce mus txog qhov ntsuas hluav taws xob ntawm avalanche tawg ntawm transistor, tom kawg yuav qhib txoj hauv kev rau kev tawm tam sim no ntawm tus capacitor txuas nrog nws. Tom qab ntawd tus coj thyristor qhib, txuas rau hauv lub nra rau hauv lub network. Thaum pib ntawm ib nrab-lub sijhawm tom ntej no, txhua yam yog rov ua dua, tabsis rov ua dua, hauv thim rov qab polarity.
Kauj ruam 4
Kho lub sijhawm ntawm tig ntawm thyristors los ntawm kev hloov qhov tsis kam ntawm lub zog tsis sib xws resistor R7 txij thaum pib mus txog thaum kawg ib nrab sijhawm. Qhov no ua rau muaj kev hloov pauv ntawm tag nrho tam sim no hauv 1st winding ntawm vuam transformer. Txo lossis nce siab hloov kho ntau yam, hloov qhov tsis kam ntawm tus tso tawm resistor R7 nce lossis nce, feem.
Kauj ruam 5
Hloov cov resistors R5, R6, uas tau suav nrog hauv cov hluav taws xob puag ncig thiab transistors VT1, VT2, uas tau ua haujlwm nyob rau hauv hom avalanche, nrog chav noj mov. Txuas cov anodes ntawm cov rooj noj mov rau huab sib txuas ntawm cov tsis haum R7, thiab txuas cov cathodes mus rau resistors R3 thiab R4. Rau cov kev cai tam sim no tau sib sau ua ke ntawm cov rooj noj mov, siv cov cuab yeej ntawm hom KN102A. Siv cov twj hloov hluav taws xob xws li P416, GT308 li VT1, VT2, tab sis koj tuaj yeem hloov lawv nrog cov kev hloov hluav taws xob tsawg niaj hnub nrog cov ntsuas zoo sib xws. Siv cov kuj tsis paub meej resistor ntawm SP-2 hom, lwm tus ntawm MLT hom. Tus tsim qauv xws li MBT lossis MBM nrog qhov ntsuas hluav taws xob ua haujlwm ntawm 400 V. Tus tswj hwm tsis xav tau kev kho kom haum, tsuas yog nco ntsoov tias cov transistors ruaj khov nyob rau hauv hom avalanche.
