R, YRKS, YRKK Series (H710~800) large-size High Voltage Wound Rotor Motor
 

結(jié)構(gòu)特點(diǎn)  Structural characteristics
　　該系列電機(jī)采用箱式鋼板結(jié)構(gòu)，拆下冷卻器或防護(hù)罩即可觀察和觸及電機(jī)內(nèi)部，便于電機(jī)的安裝維護(hù)；轉(zhuǎn)子為繞線式轉(zhuǎn)子，帶滑環(huán)結(jié)構(gòu)；定子采用F級(jí)絕緣真空壓力浸漬無(wú)溶劑工藝處理(VPI)，使電機(jī)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(cè)溫元件，電機(jī)軸承均有不停機(jī)注油和排油裝置，提高了電機(jī)自身的保護(hù)能力和運(yùn)行效率。當(dāng)電機(jī)功率超過(guò)2000kW時(shí)，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(diǎn)。
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(chǎn)品適用于：1、較大的啟動(dòng)轉(zhuǎn)矩；2、輸電線路容量不足以啟動(dòng)鼠籠型電動(dòng)機(jī)；3、啟動(dòng)時(shí)間長(zhǎng)和啟動(dòng)較頻繁；4、需要小范圍調(diào)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.
