1. Khangela iNqanaba loku-1: Ukuqinisekiswa kweNkqubo yoMbane

• Inkqubo yeCapacitor:
• Sebenzisa i-voltmeter ezinikeleyo ukukhangela amandla ombane ashiyekileyo e-capacitors yokugcina amandla (kufuneka ibe njalo<36V safe voltage).​
• Inspect the appearance of the capacitor bank: no bulging or electrolyte leakage (if electrolyte leakage >5ml, isixhobo kufuneka sivalwe ngoko nangoko).
• Inkqubo yokuGrounding:
• Vavanya ukuxhathisa komhlaba (ixabiso eliqhelekileyo<4Ω; it is recommended to use a grounding resistance tester).​
• Qinisekisa umnqamlezo{0}}ummandla wecandelo wocingo lokumisa (umcingo wobhedu Omkhulu kuno okanye olingana ne-16mm², ucingo lwealuminiyam Omkhulu kuno okanye ulingana ne-25mm²).​

2. Inqanaba lesi-2 Qwalasela: uQinisekiso lweNkqubo yeMechanical

• Inkqubo ye-Electrode:
• Measure the electrode tip wear (if diameter loss >I-20%, ukutshintshwa kuyafuneka; umzekelo, i-Φ8mm electrode iyacinywa ukuba iba<>
• Check the electrode coaxiality (if deviation >0.05mm, kwakhona{1}}ulungelelaniso luyafuneka).
• Inkqubo yoxinzelelo:
• Qhuba akukho -uvavanyo lomthwalo kwindlela yoxinzelelo lwe-servo: xa isethi yoxinzelelo yi-300N, ukuguquguquka kwemveliso.<±5%.​
• Jonga isantya sokuphendula se-cylinder/servo motor (ukulibaziseka kokusebenza<50ms).​

3. Jonga iNqanaba lesi-3: Izixhobo zoKhuseleko zoKhuseleko

• Isixhobo sokunxibelelanisa:
• Xa umkhusane wokukhanya wokhuseleko uvuselelwa, qinisekisa ukuba isixhobo sifikile ixesha lokumisa likaxakeka<15ms.​
• Vavanya umsebenzi woqhagamshelo phakathi kwesitshixo socango lwekhabhathi kunye -nesekhethi yevoltage ephezulu (amandla ombane aphezulu acinyiwe kwimizuzwana eyi-0.5 emva kokuvulwa kocango).​
• Ukhuseleko lomntu:
• Qwalasela ixabiso lamandla ombane lokumelana neeglavu zokugquma (Inkulu okanye ilingana ne-10kV; uvavanyo lunyanzelekile rhoqo kwiinyanga ezi-6).
• Verify the light transmittance of the protective mask (>I-89%, ithobela umgangatho we-EN166).

II. IiNkqubo zokuSebenza eziMgangatho (SOP).

1. Qalisa{1}}Inkqubo yokuLungiselela

• Ngaphambi kokudibanisa umbane ongundoqo, qinisekisa ukuba i-voltage regulator isetyenziselwe kwi-zero (ukuthintela ukutshaja kwe-capacitor).
• Qala inkqubo yokupholisa kwaye uqinisekise ubushushu bamanzi<35℃ (excessive temperature difference will cause capacitor capacity attenuation).​
• Yenza uvavanyo lokukhupha akukho-umthwalo ukuqinisekisa ukuzinza kokukhutshwa kwamaza (ukuguquguquka okuvumelekileyo<±3%).​

2. IiNkcazo zokuSeta iParameter yeWelding

3. Imigaqo yoKhuseleko oluSebenzayo

• Ezimbini-Umgaqo wokuSebenza kwesandla:
• Umgama phakathi kwamaqhosha okuqalisa Omkhulu kuno okanye olingana ne-300mm (ukuthintela ukuphosa{1}isandla esinye{2}}ukuvusa).​
• Zombini izandla kufuneka zicinezelwe ngokuqhubekayo de i-welding igqitywe (ukukhutshwa kuyayeka ukuba kuphazamisekile).
• Inkqubo yokuphatha engaqhelekanga:
• Kwimeko yokukhutshwa okungaqhelekanga, cofa iqhosha elibomvu lokuyeka likaxakeka ngoko nangoko (isekethi enkulu inqunyulwe<0.1 seconds).​
• Emva kokuba i-alamu yomsi iqhutywe, qalisa inkqubo yokukhupha ngaphakathi kwemizuzwana ye-30 (isantya somoya Omkhulu okanye ulingana ne-8m / s).

III. IiNgcaciso zokuSebenza kwiiMeko eziZodwa zokuSebenza

1.Izinto ezininzi zokuWelding

• Amanqaku aPhambili wokuSebenza:
• Yamkela imowudi yokukhupha enyathelweyo: amandla ombane aphantsi (200-300V/3ms) ukugqobhoza umaleko weoxide kuqala.
• Seta inkqubo yegradient yoxinzelelo: pre{0}}uxinzelelo (50N) → uxinzelelo lwewelding (300N) → ukubamba uxinzelelo (150N).​
• Imeko: Xa ishishini lebhetri lidityaniswa nge-aluminiyam eyi-0.2mm + 0.15mm nickel, ukuhambelana kwedayamitha ye-weld nugget kuye kwaphuculwa ngama-40% ngolawulo{3}}loxinzelelo lwezigaba ezithathu.​

2. Phezulu{1}}UkuPhathwa kweMathiriyeli yokuReflectivity

• Uhlengahlengiso Lwenkqubo:
• Sebenzisa i-electrode enemigangatho erhabaxa (Ra0.8→Ra3.2, ukunciphisa ukuxhathisa koqhagamshelwano ngama-60%).
• Yandisa amandla okukhutshwa nge-10% -15% ukubuyisela ilahleko yokubonakalisa
• Isilumkiso sokhuseleko: Iimaski ezikhuselayo ekukhanyeni okuqinileyo kufuneka zinxitywe (ukukhanya{0}}inombolo ekhuselayo Enkulu kuno okanye ilingana no-12).

IV. Iinkqubo zoLondolozo kunye neNkathalo

1. Izinto zoLondolozo lweMihla

• Ukugcinwa kwe-Electrode:
• Sila incam ye-electrode emva kwe-welds nganye engama-2000 (susa umaleko we-oxide kwaye ugcine i-R{1}}imilo ye-engile).
• Faka i-conductor paste ngeveki (ukunciphisa ukuchasana noqhagamshelwano kunye nokwandisa ubomi be-electrode ngama-30%)
• Ukugcinwa kweCapacitor:
• Test capacitor capacity monthly (replacement is required if attenuation rate >5%).​
• Ukuqhuba ukugcinwa kokukhutshwa okunzulu ngekota (ukukhulula intlawulo eshiyekileyo ukukhusela icrystallization ye-electrolyte).

V. IziCwangciso zokuPhatha ngokuNgxamisekileyo

1. UkuPhathwa kweNgozi yoMbane wokothuka

• Sika unikezelo lwamandla lulonke lwesixhobo ngoko nangoko (ungamchukumisi umntu owenzakeleyo ngokuthe ngqo).
• Use an insulated hook to move the electrode (safe distance >1m).​
• Yenza uncedo lokuqala lweCPR (ubunzulu boxinzelelo 5-6cm, amaxesha ngamaxesha angama-100-120 ngomzuzu).
• Gcina iliso eliqhubekayo le-ECG ngexesha lokuthuthwa kwezonyango (ukuthintela ukubanjwa kwentliziyo yesibini).

2. UkuPhathwa kweNgxaki yoMlilo

• Umlilo wokuqala: Sebenzisa isicima-mlilo sekharbon diokside (izicimi-mlilo{0}ezisekelwe emanzini azivumelekanga).​
• I-Capacitor deflagration: Yenza kusebenze inkqubo yokucudisa uqhushumbo (i-perfluorohexanone isicima-mlilo kufuneka ikhutshwe kwimizuzwana eyi-0.5).
• Evacuation route: Ensure the width of the safe passage ≥1.2m, and the visible distance of signs >15m.
