I. Tupu -Nlele nyocha ọrụ (Sistemụ nkwenye ọkwa atọ-)

1. Ọkwa 1 Lelee: Nyochaa Sistemụ eletriki

• Sistemụ Capacitor:
• Jiri voltmeter raara onwe ya nye iji chọpụta voltaji fọdụrụ nke ike nchekwa ike (ga-abụrịrị<36V safe voltage).​
• Inspect the appearance of the capacitor bank: no bulging or electrolyte leakage (if electrolyte leakage >5ml, akụrụngwa ga-emechi ozugbo).
• Sistemụ ala:
• Nwalee nguzogide ala (ụkpụrụ ọkọlọtọ<4Ω; it is recommended to use a grounding resistance tester).​
• Nyochaa obe{0}akụkụ akụkụ nke waya mgbado (waya ọla Karịrị ma ọ bụ ha nhata 16mm², waya aluminom Kariri ma ọ bụ nhata 25mm²).

2. Ọkwa 2 Lelee: Nkwenye Sistemụ Mechanical

• Usoro elektrọn:
• Measure the electrode tip wear (if diameter loss >20%, achọrọ ngbanwe; dịka ọmụmaatụ, electrode Φ8mm nwere nkwarụ ma ọ bụrụ na ọ ga-abụ<>
• Check the electrode coaxiality (if deviation >0.05mm, re{1}}a choro ntughari).
• Sistemụ nrụgide:
• Mepụta ule enweghị - na usoro nrụgide servo: mgbe nrụgide atọrọ bụ 300N, ngbanwe n'ezie nke mmepụta<±5%.​
• Lelee ọsọ nzaghachi nke moto cylinder/servo (ngbu oge ọrụ<50ms).​

3. Ọkwa 3 Lelee: Ngwa nchekwa nchekwa

• Ngwa njikọ:
• Mgbe akpalitere ákwà mgbochi ọkụ nchekwa, chọpụta na oge nkwụsị ihe mberede ngwa ngwa<15ms.​
• Nwalee ọrụ mkpọchi n'etiti mgba ọkụ ọnụ ụzọ kabinet na sekit voltaji{{0} dị elu (a na-ebipụ voltaji dị elu n'ime 0.5 sekọnd mgbe emepechara ụzọ).
• Nchekwa onwe onye:
• Lelee uru voltaji na-eguzogide nke mkpuchi mkpuchi mkpuchi (Karịrị ma ọ bụ nhata 10kV; nnwale bụ iwu nke ọnwa isii ọ bụla).
• Verify the light transmittance of the protective mask (>89%, na-agbaso ụkpụrụ EN166).

II. Usoro Ọrụ Ọkọlọtọ (SOP).

1. Malite{1}Usoro Nkwadebe

• Tupu ijikọ ọkụ ọkụ bụ isi, gosi na a tọgharịala onye na-ahụ maka voltaji ka ọ bụrụ efu (iji gbochie chaja capacitor).
• Malite usoro jụrụ oyi ma hụ na mmiri dị ọkụ<35℃ (excessive temperature difference will cause capacitor capacity attenuation).​
• Mee nnwale mwepu enweghị - iji chọpụta nkwụsi ike nke ebili mmiri a na-ahapụ (mgbanwe enwere ike).<±3%).​

2. Welding Parameter Setting Specifications

3. Iwu nchekwa ọrụ

• Abụọ-Ụkpụrụ Ọrụ Aka:
• Oghere dị n'etiti bọtịnụ mmalite Karịrị ma ọ bụ ha nhata 300mm (iji gbochie otu-aka-na-akpalite).
• A ghaghị ịpịnye aka abụọ ahụ mgbe niile ruo mgbe ịgbado ọkụ gwụchara (mpụpụ na-akwụsị ma ọ bụrụ na ọ kwụsịrị).
• Usoro njikwa adịghị mma:
• Ọ bụrụ na enwere mwepu, pịa bọtịnụ nkwụsị ihe mberede na-acha uhie uhie ozugbo (ebipụrụ isi sekit<0.1 seconds).​
• Mgbe a kpalitere mkpu anwụrụ ọkụ, malite usoro ikpochapu n'ime 30 sekọnd (ifufe ọsọ karịa ma ọ bụ nhata 8m/s).

III. Nkọwapụta arụmọrụ maka ọnọdụ ọrụ pụrụ iche

1. Multi-Ibe oyi akwa dị ka ihe ịgbado ọkụ

• Isi ihe eji arụ ọrụ:
• Nabata ọnọdụ mwepụ steepụ: obere voltaji (200-300V / 3ms) ka ibu ụzọ mebie oyi akwa oxide.
• Tọọ mmemme gradient nrụgide: tupu -nrụgide (50N) → nrụgide ịgbado ọkụ (300N) → njide nrụgide (150N).
• Ikpe: Mgbe ụlọ ọrụ batrị gbanyere 0.2mm aluminom + 0.15mm nickel, agbanwe agbanwe nke dayameta weld nugget ka emelitere site na 40% ruo atọ{3}} njikwa nrụgide ọkwa.

2. Elu -Njikwa ihe na-atụgharị uche

• Ndozi usoro:
• Jiri eletrọd nwere elu dị nro (Ra0.8 → Ra3.2, na-ebelata nguzogide kọntaktị site na 60%).
• Mụbaa ike mwepu site na 10%-15% iji kwụọ ụgwọ mfu ntụgharị uche
• Ịdọ aka ná ntị Safety: A ghaghị iyi ihe mkpuchi nchebe megide ọkụ siri ike (ìhè{0}}nọmba nchekwa karịrị 12 ma ọ bụ hà nhata).

IV. Usoro nlekọta na nlekọta

1. Ihe nlekọta kwa ụbọchị

• Nlekọta Electrode:
• Ghichaa n'ọnụ electrode mgbe weld 2000 ọ bụla (wepụ oyi akwa oxide wee chekwaa ọdịdị akụkụ R-).
• Tinye mmado na-eduzi kwa izu (na-ebelata nguzogide kọntaktị na ịgbatị ndụ electrode site na 30%)
• Nlekọta Capacitor:
• Test capacitor capacity monthly (replacement is required if attenuation rate >5%).​
• Na-emezi mmezi mkpofu miri emi kwa nkeji anọ (wepụta ụgwọ fọdụrụnụ iji gbochie kristal electrolyte).

V. Atụmatụ njikwa ihe mberede

1. Njikwa ihe mberede ọkụ eletrik

• Wepụ mkpokọta ike nke akụrụngwa ozugbo (emetula onye merụrụ ahụ aka ozugbo).
• Use an insulated hook to move the electrode (safe distance >1m).​
• Mee enyemaka mbụ CPR (mmetụta mkpakọ 5-6cm, ugboro 100-120 ugboro kwa nkeji).
• Na-aga n'ihu nlekota ECG n'oge njem ahụike (iji zere njide obi nke abụọ).

2. Ijikwa ihe mberede ọkụ

• Ọkụ mbụ: Jiri ọkụ carbon dioxide (mmiri -ihe ọkụ na-eme ka amachibidoro).
• Mmebi nke Capacitor: Mee ka sistemu mgbawa ahụ rụọ ọrụ (a ga-ahapụrịrị onye na-emenyụ ọkụ perfluorohexanone n'ime sekọnd 0.5).
• Evacuation route: Ensure the width of the safe passage ≥1.2m, and the visible distance of signs >15m.
