結構特點 Structural characteristics
該系列電機采用箱式鋼板結構，拆下冷卻器或防護罩即可觀察和觸及電機內部，便于電機的安裝維護；轉子為繞線式轉子，帶滑環結構；定子采用F級絕緣真空壓力浸漬無溶劑工藝處理(VPI)，使電機具有可靠的絕緣性能和防潮、抗沖擊能力；定子和軸承均裝有PT100測溫元件，電機軸承均有不停機注油和排油裝置，提高了電機自身的保護能力和運行效率。當電機功率超過2000kW時，可按用戶要求，多配一副出線盒，用于引出三相繞組中的中性點。
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. When the power is more than 2000kW, according to the requirement of customer, another terminal box can be installed to pick up the neutral point of winding.
該系列產品適用于：1、較大的啟動轉矩；2、輸電線路容量不足以啟動鼠籠型電動機；3、啟動時間長和啟動較頻繁；4、需要小范圍調速。
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.
