Intshayelelo
Kwiimeko ezifana nebhetri entsha yemoto yamandla epakisha ukuwelda kunye nokuchaneka kokwenziwa kwecandelo lombane, iimpazamo zokusebenza i-low-energy capacitor discharge weldingkunokukhokelela kwiziganeko eziphambili zomgangatho. Amanani-nkcazo amashishini abonisa ukuba ama-65% okusilela kwezixhobo kubangelwe-kukuhlolwa okungaqhelekanga, ngelixa ukusebenza ngokungafanelekanga kukhokelela kwireyithi yokulahlwa kwemveliso ukuya kutsho kwi-12%. Eli nqaku lichaza ngokulungelelanisiweyo uluhlu lokuhlola olungaphambili{5}} kunye nemigaqo yokusebenza esemgangathweni (SOP) ye i-low-energy capacitor discharge welding, equka{0}}inkqubo yolawulo olupheleleyo ukusuka kulungiselelo loqaliso ukuya ekuphatheni imeko engaqhelekanga, ukunceda amashishini aphumeze zombini ukhuseleko kunye noqinisekiso lomgangatho.
I. Phambi{1}}Uludwe lokuHlola lokuSebenza ({2}}Inkqubo yoQinisekiso lweNqanaba lesithathu)
1. INqanaba loku-1 Hlola: Ukuqinisekiswa kweNkqubo yoMbane
- Inkqubo yeCapacitor:
Sebenzisa i-voltmeter ezinikeleyo ukujonga i-voltage eshiyekileyo yee-capacitors zokugcina amandla (kufuneka ibe njalo<36V safe voltage).
Inspect capacitor bank appearance: no bulging or leakage (stop immediately if electrolyte leakage >5ml).
- Inkqubo yokuGrounding:
Uvavanyo lokumelana nomhlaba (ixabiso eliqhelekileyo<4Ω, recommended use of ground resistance tester).
Qinisekisa indawo enqamlezileyo{0}}yecandelo locingo olusemhlabeni (umcingo wobhedu Omkhulu kuno okanye olingana ne-16mm², i-aluminiyam yocingo Mkhulu okanye ilingana ne-25mm²).
2. INqanaba lesi-2 ukujonga: uQinisekiso lweNkqubo yoomatshini

Vavanya umsebenzi woqhagamshelo phakathi kokutshintsha kocango lwekhabhathi kunye -nesekhethi yevoltage ephezulu (ukucima amandla ombane aphezulu kwimizuzwana eyi-0.5 emva kokuvulwa kocango).
- Ukhuseleko lomntu:
Qwalasela ukuxhathisa amandla ombane weglavu (Inkulu okanye ilingana ne-10kV, kufuneka ivavanywe rhoqo kwiinyanga ezi-6).
Verify protective face shield light transmittance (>I-89%, ihambelana nomgangatho we-EN166).
II. IiNkqubo zokuSebenza eziMgangatho (SOP)
1. Inkqubo yokuLungiselela uQalo
- Qinisekisa ukuba isilawuli samandla ombane sibuyela ku-zero phambi kokuba uqhagamshele umbane ongundoqo (kuthintela ukutshaja kwe-capacitor).
- Qala inkqubo yokupholisa, qinisekisa ubushushu bamanzi<35℃ (excessive temperature difference causes capacitor capacity decay).
- Ungenzi{0}}uvavanyo lokukhutshwa komthwalo ukuqinisekisa ukuzinza kohlobo lwamaza okukhutshwa (ukuguquguquka okuvumelekileyo<±3%).
2. I-Welding Parameter Setting Standards

| Ixesha lokukhupha | Lungisa ngokusekwe kwi-thermal conductivity (mfutshane yobhedu, ende yentsimbi) | 1mm ipleyiti yentsimbi: 8-12ms |
| Uxinzelelo lwe-Electrode | Landela ifomula F=K×T² (T: ubukhulu bepleyiti) | 0.8mm ipleyiti yobhedu: 220-260N |
| Isithuba sokukhupha | Inkulu kunokuba okanye ilingana namaxesha ama-2 okukhupha ixesha (ukuthintela ukufudumeza kwe-capacitor) | Ukukhutshwa kwe-12ms kufuna ikhefu le-24ms |
3. Imithetho yoKhuseleko yoMsebenzi
- Ezimbini-Umgaqo wokuSebenza kwezandla:
Isithuba seqhosha lokuqala Elikhulu kuno okanye elilingana ne-300mm (thintela ngengozi enye -ukuvusa isandla).
Izandla kufuneka zicofe ngokuqhubekayo de i-welding igqitywe (yeka ukukhupha ukuba kuphazamisekile).
- Inkqubo yokuphatha engaqhelekanga:
Cinezela iqhosha elibomvu lokumisa likaxakeka ngoko nangoko xa kukho into engaqhelekanga yokukhupha ( cima isekethe enkulu<0.1 seconds).
Vula inkqubo yokukhupha ngaphakathi kwemizuzwana engama-30 emva kokuba i-alamu yomsi ibangela (isantya somoya esikhulu okanye esilingana ne-8m/s).
III. ImiGangatho yokuSebenza kwiMeko eYodwa
1. I-Multi-Imaleko Engafaniyo yokuWelding
- Amanqaku aPhambili oMsebenzi:
Imowudi yokukhutshwa kwenyathelo: i-voltage yokuqala ephantsi ukuphula umaleko we-oxide (200-300V / 3ms).
Cwangcisa inkqubo yegradient yoxinzelelo: pre{0}}uxinzelelo (50N) → uxinzelelo lwewelding (300N) → ubambe uxinzelelo (150N).
Ityala: Ishishini lebhetri liphucule ukuhambelana kwedayamitha ye-nugget ngama-40% ngolawulo lwenqanaba lesithathu-loxinzelelo loxinzelelo xa welding 0.2mm aluminiyam + 0.15mm nickel.
2. High Reflectivity Material Handling
- Uhlengahlengiso lweNkqubo:
Sebenzisa umphezulu-i-electrodes erhabaxa (Ra0.8→Ra3.2, ukuxhathisa koqhagamshelwano kuncitshiswe ngama-60%).
Ukwandisa amandla okukhutshwa nge-10% -15% ukubuyisela ilahleko yokubonakalisa.
- Isilumkiso soKhuseleko: Kufuneka unxibe i-anti{0}}ikhuselo lobuso obumenyezelayo (inani lomthunzi Omkhulu kuno okanye lilingana no-12).
IV. Iinkqubo zoLondolozo
1. Izinto zokuLondolozwa kweMihla
- Ukugcinwa kwe-Electrode:
Incam ye-electrode yokunxiba rhoqo ngo-2000 we-welds (susa umaleko we-oxide, gcina i-R-i-engile shape).
Faka isicelo se-conductive paste ngeveki (ukunciphisa ukuchasana noqhagamshelwano, ukwandisa ubomi be-electrode ngama-30%).
- Ukugcinwa kweCapacitor:
Monthly capacitance test (replace if decay rate >5%).
Ukugcinwa kokukhutshwa okunzulu kwekota (ukukhulula intlawulo eseleyo, ukuthintela icrystallization ye-electrolyte).
2. Umjikelo woTshintsho lweCandelo eliPhambili
| Igama lecandelo | Ukutshintshwa komgangatho | Ubomi obuqhelekileyo |

| Discharge Switch | Action count >100,000 or contact resistance >50mΩ | 6-12 iinyanga |
| I-Capacitor yokugcina amandla | Capacity decay >15% or ESR >200% ixabiso lokuqala | Iminyaka emi-3-5 (kuxhomekeke kumaxesha amaninzi) |
| Inzwa yoxinzelelo | Linearity error >1% FS | 2-3 iminyaka |
V. Isicwangciso sokuPhendula ngokuNgxamisekileyo
1. UkuPhathwa kwesiganeko sokuThwatywa koMbane
- Ngoko nangoko zinqumle izixhobo eziphambili amandla (musa ukubamba ngqo abonzakeleyo).
- Use insulated hook to move electrodes away (safe distance >1m).
- Yenza i-CPR (ubunzulu be-compression 5-6cm, i-frequency 100-120 amaxesha / umzuzu).
- Ukujongwa kwe-ECG eqhubekayo ngexesha lokuthutha (ugweme ukubanjwa kwentliziyo yesibini).
2. UkuPhathwa kweNgxaki yoMlilo
- Umlilo wokuqala: Sebenzisa ikharbon dayokhsayidi isicima-mlilo (amanzi{0}awalelwenga).
- Uqhushumbo lweCapacitor: Yenza kusebenze inkqubo yokucinezela (khulula isicima-mlilo se-perfluorohexanone ngaphakathi kwemizuzwana eyi-0.5).
- Evacuation route: Ensure safety passage width ≥1.2m, signage visible distance >15m.
