I-Insulation Level of Explosion-Proof Motor

Xa kuxoxwa ngamanqanaba e-insulation, umba wokunyuka kwamaqondo obushushu kwiimotor-proof-proof motors uba yimfuneko. Inyaniso, kukho imiba emibini engundoqo ekufuneka kufikelelwe kuyo imvumelwano:

Class F Insulation:

Okwangoku, ngaphaya 90% yeenjini zamandla ombane aphezulu naphantsi ezingangqini ukudubula e-China zigqunyiweyo zodidi F. Ukwandisa ixesha lokuphila kweemotor-proof-proof, engaphezulu kwe 90% yabenzi bonisa “Ukufakelwa kweklasi F, ubushushu ukunyuka kuhlolwe yimida yeKlasi B” kwiisampuli zabo. Ukugquma kodidi B kuvumela ubushushu obuyi-130°C, ngoxa udidi F luvumela ukuya kuthi ga kwi-155°C. Ukuqwalasela ubushushu bendalo obungama-40°C, inkqubo yokuvelisa kunye nokuguquguquka kwempahla ye-5°C kunye ne-10°C, i umzi-mveliso Umlinganiselo wokunyuka kobushushu kudidi B olugqunyiweyo lweenjini ezinobungqina bokudubula lusetelwe ku-80K, nakwiKlasi F, yi 90k (95I-K yeenjini ezikhusela uqhushumbo phantsi komhlaba).

I-Class H ye-Insulation:

Ukugquma kweKlasi H kuvumela ubushushu obuyi-180°C. Nangona kunjalo, uyilo, imveliso, iibheringi, kunye nezithambisi zeenjini zokumelana nokudubula koHlelo H azikasetyenziswa ngokubanzi eTshayina. Kubavelisi, ukuvelisa i-Class H i-insulated windings ayikho nzima; umngeni ukwizinga eliphezulu lobushushu. Ngoko ke, ngaphandle kokuba kuyimfuneko (njengakwimo engqongileyo enamaqondo obushushu angama-60°C, okanye phi Injini yokuthintela uqhushumbo ubungakanani bulinganiselwe), Ukusetyenziswa kweenjini ze-H ezigqunyiweyo ezingaqhushumbayo kufuneka kuphetshwe.
