花鍵齒較多、工作面積大、承載能力較高；鍵均勻分布，各鍵齒受力較均勻；齒軸一體且齒槽淺、齒根應(yīng)力集中小，強(qiáng)度高且對軸的強(qiáng)度削弱；軸上零件對中性好、導(dǎo)向性較好。所有這些平鍵無可比擬的優(yōu)點(diǎn)，注定花鍵于用作電機(jī)軸伸。 所謂電流互感器的極性是指它的一次繞組和二次繞組間電流方向的關(guān)系。按照規(guī)定，電流互感器一次繞組的首端標(biāo)為L1，尾端標(biāo)為L2;二次繞組的首端標(biāo)為K1，尾端標(biāo)為K2。在接線中，L1和K1稱為同極性端，L2和K2也稱為同極性端。 1.電流互感器在工作時二次側(cè)不得開路。由于電流互感器二次阻抗很小，正常工作時，二次側(cè)接近于短路狀態(tài)。當(dāng)二次側(cè)開路時，會感應(yīng)出很高的電壓，危及人身和設(shè)備。因此，電流互感器二次側(cè)不允許開路，二次回路接線必須可靠、牢固，不允許在二次回路中接人開關(guān)或熔斷器。

如果一個電連通的回路在變電所的不同點(diǎn)同時接地，地網(wǎng)上的電位差將串入這個連通的回路，有時會造成不必要的分流。在現(xiàn)實中，常常由于人為的接線錯誤及電纜絕緣的老化等原因，造成一個電氣連接的二次回路中出現(xiàn)多點(diǎn)接地的情況多有發(fā)生，以致引發(fā)保護(hù)誤動作事故，漫灣電廠就出現(xiàn)了這種事故。 1、輸入電壓范圍：在環(huán)境溫度25’c下，固態(tài)繼電器能夠工作的輸入電壓范圍。2、輸入電流：在輸入電壓范圍內(nèi)某一特定電壓對應(yīng)的輸入電流值。3、接通電壓：在輸入端加該電壓或大于該電壓值時，輸出端確保導(dǎo)通。4、關(guān)斷電壓：在輸入端加該電壓或小于該電壓值時，輸出端確保導(dǎo)通。
