1) otutu afẹfẹ ibaramu
1) Ṣiyesi iwọn otutu ibaramu ti o pọju lati mu yara ti ogbo ti awọn ẹya ṣiṣu, opin oke ko ju +40 ℃.
Ṣiyesi pe iwọn otutu ibaramu kekere ti o pọju pupọ
ṣe iyipada ibamu ti ọmọ ẹgbẹ igbekale, opin isalẹ ko kere ju -5℃.
Ṣiyesi igbesi aye iṣẹ ti fifọ Circuit, iye apapọ ti awọn wakati 24 ko ju + 35 ℃.
Akiyesi:
① Ipo iṣẹ ti iye iwọn kekere jẹ -10 ℃ tabi -25 ℃.Olumulo nilo lati kede si ile-iṣẹ nigbati o ba paṣẹ.
②Ipo iṣẹ ti iye iwọn oke ti o kọja +40 ℃ tabi iye iye to kere ju -25℃, olumulo nilo lati duna pẹlu ile-iṣẹ naa.
2) Ipo fifi sori ẹrọ
Giga ko kọja 2000m;
Awọn ibeere Circuit Idaabobo;
Aaye fifi sori ẹrọ ṣe iṣiro kukuru kukuru lọwọlọwọ Ik kii ṣe ju 3000A;
Awọn fifọ Circuit yoo wa ni fi sori ẹrọ ni ibamu pẹlu awọn ibeere ti lilo iwe, inaro inaro ti awọn Circuit fifọ ko koja 5 °, Awọn ayika gbigbọn ni ko siwaju sii ju 5g.
3) Awọn ipo Afẹfẹ
Ọriniinitutu ojulumo ti oju-aye ko kọja 50% ni iwọn otutu afẹfẹ ibaramu +40 ° C. O le ni ọriniinitutu ibatan ti o ga ni awọn iwọn otutu kekere.Ọriniinitutu ojulumo oṣooṣu ti o pọju ti oṣu tutu jẹ 90%, ati apapọ iwọn otutu ti o kere ju fun oṣu jẹ +25 ° C ati ṣe akiyesi ifunmọ lori oju ọja nitori awọn iyipada iwọn otutu.
4) ipele idoti
Ipele idoti jẹ ipele 3.
5) Ẹka fifi sori ẹrọ
Circuit idabobo idabobo ti fi sori ẹrọ ni ẹka III.
6) Abala agbelebu okun waya ti tunto ni ibamu si lọwọlọwọ alapapo mora ti o pọju Ith ti fifọ Circuit.
