Insulation theem ntawm Explosion-Proof Motor

Thaum tawm tswv yim txog insulation theem, Qhov no kub sawv hauv explosion-proof motors yuav relevant. Qhov tseeb, Muaj ob tug tseem ceeb ntsiab lus uas kev pom zoo yuav tsum tau mus txog:

Hoob Kawm F Insulation:

tam sim no, dhau 90% Siab thiab tsis voltage tawg-profo motors nyob Suav teb yog hoob kawm F insulated. Mus cuag lub lifespan ntawm explosion-proof motors, ntau tshaj 90% manufacturers qhia “Hoob Kawm Fsulation, txias sawv ntsuam xyuas los ntawm hoob kawm B txwv” nyob rau hauv lawv cov qauv. Hoob kawm B insulation tso cai rau ib kub ntawm 130°C, Thaum hoob kawm F mus txog 155°C. Xav txog tej yam kub ntawm 40°C, Manufacturing txheej txheem thiab khoom fluctuations ntawm 5°C thiab 10°C, qhov Hoobkas Kub sawv txwv rau hoob kawm B insulated tawg-profo motors yog teem rau 80K, thiab rau Hoob Kawm F, nws yog 90K (95K rau underground tawg-pov thawj motors).

Hoob Kawm H Insulation:

Hoob kawm H insulation tso cai rau ib kub ntawm 180°C. tiam sis, tsim, manufacturing, bearings, Thiab covricants rau hoob kawm H tawg-profo motors yuav tsis tau lug thov nyob suav teb. Rau manufacturers, ua hoob kawm H insulated windings yuav tsis yooj yim; Txoj kev sib tw lus dag hauv high-kub bearings. Yog li ntawd, vim, tshwj tsis yog tsim nyog (Xws li nyob rau tej cheeb tsam uas muaj peevxwm ntawm 60°C, los yog qhov twg tawg-profo qhov me me xwb), Siv hoob kawm H insulated tawg-profo motors yuav tsum tau pov tseg.
