Ua ntej thawj lub hwj chim- tom qab magnesium oxide refilling, sintering thiab txias yuav tsum tau ua kom tiav, ib tug txias - lub xeev xeem yuav tsum dhau, thiab rwb thaiv tsev yuav tsum tau raws li cov qauv los tiv thaiv kev puas tsuaj, luv luv Circuit Court, los yog cov khoom puas.
Cov kev npaj tseem ceeb ua ntej thawj lub hwj chim- rau:
Paub meej tias ua tiav sintering thiab txias:
Sintering yuav tsum tuav ntawm 800-1000℃rau 1-2 teev kom paub meej txaus recrystallization ntawm cov nplej; Ntuj cua txias hauv qhov cub rau<200℃ should be used, followed by further cooling to room temperature (approximately 25℃) after removal from the furnace, taking 3–5 hours in total; Forced cooling such as water cooling or air cooling is strictly prohibited to avoid thermal stress cracking.
Ua txias-kev ntsuas kev ua haujlwm hauv xeev thiab ua tau raws li cov qauv.
Rwb thaiv tsev tiv thaiv kev ntsuas: ntsuas siv calibrated 2500V megohmmeter, tshwm sim ntau dua lossis sib npaug rau 500 MΩ (500V DC);
Kev ntsuas qhov ntsuas hluav taws xob: Siv AC 2000V rau 1 feeb yam tsis muaj kev puas tsuaj lossis flashover;
Qhov chaw kuaj yuav tsum qhuav (RH Tsawg dua lossis sib npaug li 30%), tshem tawm qhov cuam tshuam los ntawm qhov chaw.
Tshawb xyuas cov khoom siv lub cev:
Cov hlau casing yuav tsum tsis muaj deformation, tawg, los yog bulges;
Cov hlau lead terminals yuav tsum tau muab kaw kom zoo siv ceramic sealant lossis hlau sealant, nrog rau kev tiv thaiv ntawm IP65 lossis siab dua;
Cov hlau lead yuav tsum ruaj ntseg crimped, nrog kev tiv thaiv kev tiv thaiv<0.03Ω, and free from oxidation or loosening.
Installation thiab ib puag ncig npaj:
Nruab cov cua sov kom raug rau hauv cov khoom siv, kom tsis txhob muaj kev ntxhov siab;
Cov kab hluav taws xob yuav tsum tau txuas nrog lub tshuab hluav taws xob tiv thaiv tam sim no thiab lub tswb hluav taws xob overcurrent;
Qhov chaw ib puag ncig yuav tsum huv thiab qhuav, tsis txhob muaj plua plav lossis ya raws. Tag nrho cov kev npaj yuav tsum ua kom tiav ua ntej lub hwj chim muab. Lub hwj chim yuav tsum tsis txhob muab yog tias ib kauj ruam twg tsis ua raws li tus qauv txhawm rau tiv thaiv kev nyab xeeb.
