Ar aislamiento ar motor ntsa̲ explosiones

Nu'bu̲ mi ñä ar niveles ar aislamiento, Tema ar aumento mpat'i ja ya motores ntsa̲ explosiones cobra relevancia. Jar gu̲ki makwäni, Jawa yoho puntos clave dige mi ge mahyoni zo̲ni 'nar consenso:

Aislamiento jar nsa̲di F:

'Bu̲'bya, dige 90% ja ya motores ntsa̲ explosiones hñets'i ne jár voltaje jar Ntxinä gi 'bu̲hu̲ aislados jar nsa̲di F. To extend the lifespan of explosion-proof motors, more than 90% of manufacturers indicate “Class F insulation, Tsoxpa rise assessed by Class B limits” in their samples. Class B insulation allows a temperature of 130°C, while Class F permits up to 155°C. Considering an environmental temperature of 40°C, manufacturing process and material fluctuations of 5°C and 10°C, ar fábrica temperature rise limit for Class B insulated explosion-proof motors is set to 80K, and for Class F, it is 90K (95K for underground explosion-proof motors).

Class H Insulation:

Class H insulation permits a temperature of 180°C. 'Ñotho ar embargo, the design, fabricación, bearings, and lubricants for Class H explosion-proof motors are not yet widely applied in China. For manufacturers, producing Class H insulated windings is not difficult; the challenge lies in high-temperature bearings. Ir, unless necessary (such as in environments with temperatures of 60°C, or where motor ntsa̲ explosiones size is limited), the use of Class H insulated explosion-proof motors should be avoided.
