Feature and usage
high voltage explosion proof type three-phase asynchronous motor mounting dimensions conform to the national standard of China, the power range from 160KW to 1400KW. Motor meets the national standard GB3836.1 - 2000 "China explosive gas environment for electrical equipment part first: General requirements" and GB3836.2 2000 "explosive gas environment for electrical equipment Part second: Flameproof Enclosures" d "rules, made of flame-proof type dI, dIIAT4, dIIBT4, suitable for explosive gas mixture place.
Class I: dI, is applicable for places and coal mine methane or coal mines exist explosive gas mixture of non mining working surface for electrical equipment;
II type: suitable for use in electrical equipment factory.
DIIAT4, the factory has class IIA, T1, T2, T3, existing T4 group explosive gas mixture places;
DIIBT4, IIA, IIB class factories with presence of T1, T2, T3, T4 group explosive gas mixture, place;
The protection grade series motor body shell are designed according to the IP54, can be made of IP55; the junction box is IP54, can be made into IP55;
The corresponding relations between power, speed and frame size motor is shown in Table 1, table 2 (6000V) (10000V), technical data see Table 3, table 4 (6000V) (10000V);
