1、粉塵防爆型三相錐形轉(zhuǎn)子異步電動機使用于工作環(huán)境溫度－30～＋40攝氏度，海撥不超過1000米的場合。

1. The dust protect motor of taper rotor is used in environment temperature -30～+40℃, Altitude under 1000m.

2、防爆電動機的電源為三相正弦交流電，額定頻率為50Hz，額定電壓為380V。（特殊要求可單獨設(shè)計，如50Hz415V、60Hz220/380V、60Hz220/440V等等）。當(dāng)防爆電動機接線端的電壓不低于額定值的90％時（頻率為額定值），隔爆電動機仍能正常工作。

2. The power of the dust protect motor of taper rotor is three phase alternating current of sine , rated frequency is 50Hz ,rated voltage is 380V ,(The special request can singleness design , such as 50Hz415V、60Hz220/380V、60Hz220/440V).When the terminal voltage not less than 90%(the frequency is rated),the motor can well-balanced operate .

3、防爆電動機的工作制度為JC25％，絕緣等級為F級，符合GB12476.1-2000《可燃性粉塵環(huán)境用電氣設(shè)備 第1部分：用外殼和限制表面溫度保護的電氣設(shè)備》以及JB/T9008.3-1999.

3. The working restrict of the dust protect motor of taper rotor is JC25% .the insulation grade is F , According as the national standard GB12476.1-2000《 Electrical apparatus for use in the presence of combustible dust—part 1: Electrical apparatus protected by enclosures and surface temperature limitation 》ａnd JB/T9008.3-1999.
