YB系列高压隔爆型三相异步电动机
YB range of flame-proof three- phase induction motor for higher
YB355-450系列
一、概述
YB355－450隔爆型高压三相异步电动机，符合JB8674－1997《YB系列高压隔爆型三相异步电动机技术条件（机座号355－450）》的规定。本系列电动机具有结构合理、性能可靠、工艺水平高、噪声低、效率高、使用寿命长等特点。
本系列电动机防爆性能符合GB3836.1－2000《爆炸性气体环境用电气设备 第1部分：通用要求》和GB3836．2－2000《爆炸性气体环境用电气设备 第2部分：隔爆型“d”》的规定，制成隔爆型。防爆标志为dI、dIIAT4、dIIBT4、dIICT4。分别使用于煤矿井下固定式设备及工厂IIA级、IIB级、IIC级，温度组别为T1－T4组可燃性气体或蒸汽与空气形成的爆炸性混合的场所。
二、结构形式及基本参数
电动机的主体外壳防护等级为IP44或IP54，接线盒为IP54。电动机的冷却方法为IC411或IC511；绝缘等级为F级；安装方式为IMB3。工作方式为S1连续工作制。额定频率为50Hz，额定电压为6000V。

1. General
YB355-450 range of flame-proof three-phase high-voltage motors complies with JB8674-1997<< The specification of YB range of flame-proof three -phase high-voltage motors ( frame size 355-450 ) >>. This range of motors has advantages of construction reasonable, characteristic reliable, technology level high, noise low, efficiency high, life long ,etc.
The explosion-proof characteristic which conforms to GB3836.1-2000 < < General Requirements- - Electrical Apparatus Used in Explosive Atmosphere Part 1 >> and GB3836.2-2000 << Flame-proof "d"- - Electrical Apparatus Used in Explosive Atmosphere Part 2 >> can be made into flame-proof type. This range of motors, whose explosive marking is dI, dIIAT4, dIIBT4 and dIICT4, can respectively used in places where there are flammable gas and the mixture of the vapour and air in the coal mining and factory where the protection degree is IIA,IIB or IIC and temperature is T1-T4.
2. Construction and Basic Parameter
The enclosure of motors is IP44 and IP54, while the terminal box IP54.The cooling system is ICO141 or ICO151. The insulation class is F. The mounting arrange is IMB3. The duty type is continue S1. The rated frequency is 50Hz. The rated voltage is 6,000V.
