YR, YRKS, YRKK 系列中型高压三相异步电动机

　　结构特点 Structural characteristics

　　中型高压三相异步电动机采用箱式钢板结构，拆下冷却器或防护罩即可观察和触及电机内部，便于电机的安装维护;转子为绕线式转子，带滑环结构;定子采用F级绝缘真空压力浸渍无溶剂工艺处理(VPI)，使电机具有可靠的绝缘性能和防潮、抗冲击能力;定子和轴承均装有PT100测温元件，电机轴承均有不停机注油和排油装置，提高了电机自身的保护能力和运行效率。

　　This series motors with box type steel structure, can be observed its interior after removing the cooler or protective cover, and esay to be installed and maintained; Wound rotor is installed with slip ring structure; Insulation class F stator made by VPI process, ensure the reliability of insulation, moisture-proof and shock resistance; Temperature senor for stator and bearing, non-stop oil filling and exit pipe, improve the protection ability and operation efficiency of the motors.

　　该系列产品适用于：1、较大的启动转矩;2、输电线路容量不足以启动鼠笼型电动机;3、启动时间长和启动较频繁;4、需要小范围调速。

　　This series motor can be applied to the requirements as follows: 1. The lager starting torque; 2. Power capacity is not enough to start a squirrel cage motor; 3. Long start time or start more frequently; 4. Adjust speed in a small range.
