三相異步電動機的三角接法和星型接法區別（把123看為首，456視為尾，首首相連為Y（星）型接法，首尾相連為角型接法）兩種接法，與我們的接入沒什么關系，如圖2和3，D1。D2。D3接A。B。究竟采用哪種接法，需要看電機銘牌，這和繞組有關系。KTK-0192T,KTK-0193S,KTK-0193T,KTK-0261S,KTK-0262S,KTK-0262T,KTK-0263S,KTK-0263T,KTK-0271S,KTK-0272S,KTK-0272T,KTK-0273S,KTK-0273T,KTK-0281S,KTK-0282S,KTK-0282T,KTK-0283S,KTK-0283T,KTK-0291S,KTK-0292S,KTK-0292T,KTK-0293S,KTK-0293T,KTK-0361S,KTK-0362S,KTK-0362T,KTK-0363S,KTK-0363T,KTK-0371S,KTK-0372S,KTK-0373S,KTK-0373T,KTK-0381S,KTK-0382S,KTK-0382T,KTK-0383S,KTK-0383T,KTK-0391S,KTK-0392S,KTK-0392T,KTK-0393S,KTK-0393T,KTA-161A1S,KTA-161A2S,KTA-161A2T,KTA-161R1S,KTA-161R2S,KTA-161R2T,KTA-162A1S,KTA-162R1S,KTA-163A1S,KTA-163A2S,KTA-163R1S,KTA-163R2S,KTA-164A1S,KTA-164A2S,KTA-164R1S,KTA-164R2S,KTA-171A1S,KTA-171A2S,KTA-171A2T,KTA-171R1S,KTA-171R2S,KTA-171R2T,KTA-172A1S,KTA-172R1S,KTA-173A1S,KTA-173A2S,KTA-173R1S,KTA-173R2S,KTA-174A1S,KTA-174A2S,KTA-174R1S,KTA-174R2S,KTA-181A1S,KTA-181A2S,KTA-181A2T,KTA-181R1S,KTA-181R2S,KTA-181R2T,KTA-182A1S,KTA-182R1S,KTA-183A1S,KTA-183A2S,KTA-183R1S,,韓國電材K120-380V4Y,120kA,3P,380V,4W,320V型號齊全 用公式表示為如果線圈的匝數有N匝，那么，線圈的感應電動勢為2.楞次定律通過實驗觀察，我們發現：當磁鐵線圈時，原磁通在增加，線圈所產生的感應電流的磁場方向總是與原磁場方向相反，即感應電流的磁場總是阻礙原磁通的增加。
但接線復雜，導線較粗，不是理想方案。四、熱繼電器的整定電流什么是熱繼電器的整定電流熱繼電器的整定電流就是使熱繼電器長時間不動作時的電流，通過熱繼電器的電流超過整定電流時，熱繼電器就立即動作。怎樣熱繼電器的整定電流。KTA-183R2S,KTA-184A1S,KTA-184A2S,KTA-184R1S,KTA-184R2S,KTA-191A1S,KTA-191A2S,KTA-191A2T,KTA-191R1S,KTA-191R1S,KTA-191R2T,KTA-192A1S,KTA-192R1S,KTA-193A1S,KTA-193A2S,KTA-193R1S,KTA-193R2S,KTA-194A1S,KTA-194A2S,KTA-194R1S,KTA-194R2S,KTB-161A1S,KTB-161A2S,KTB-161A2T,KTB-161R1S,KTB-161R2S,KTB-161R2T,KTB-162A1S,KTB-162R1S,KTB-163A1S,KTB-163A2S,KTB-163R1S,KTB-163R2S,KTB-164A1S,KTB-164A2S,KTB-164R1S,KTB-164R2S,KTB-171A1S,KTB-171A2S,KTB-171A2T,KTB-171R1S,KTB-171R2S,KTB-171R2T,KTB-172A1S,KTB-172R1S,KTB-173A1S,KTB-173A2S,KTB-173R1S,KTB-173R2S,KTB-174A1S,KTB-174A2S,KTB-174R1S,KTB-174R2S,KTB-181A1S,KTB-181A2S,KTB-181A2T,KTB-181R1S,KTB-181R2S,KTB-181R2T,KTB-182A1S,KTB-182R1S,KTB-183A1S,KTB-183A2S,KTB-183R1S,KTB-183R2S,KTB-184A1S,KTB-184A2S,KTB-184R1S,KTB-184R2S,KTB-191A1S,KTB-191A2S,KTB-191A2T,,韓國電材K120-380V4Y,120kA,3P,380V,4W,320V型號齊全 當電源電壓一定時，電源低，對電動機的運行是不利的。首先電動機的磁通密度會增加，導致鐵芯磁通飽和，這時產生磁通的激磁電流增加，所以它的增加會使電動機的定子總電流增加，電動機的鐵損銅損增大，從而使電動機效率降低，量增大，溫升增加。
我自己曾經拆電度表的電流線時，遇到過短接不牢靠，端子處噼里啦放電現象。那么電流互感器二次為什么不能開路呢。是什么原理呢。會產生什么樣的后果呢。下面為大家仔細的分析，希望大家都能理解。電流互感器正常工作（不開路）電流互感器正常工作的時候，次級所接負載為電流表或電度表電流線圈以及變送器等，這些線圈的阻抗都很小，基本上運行在短路狀態。KTB-191R1S,KTB-191R1S,KTB-191R2T,KTB-192A1S,KTB-192R1S,KTB-193A1S,KTB-193A2S,KTB-193R1S,KTB-193R2S,KTB-194A1S,KTB-194A2S,KTB-194R1S,KTB-194R2S,KTH-U1162S,KTH-U1172S,KTH-U1182S,KTH-U1192S,KTH-U1262S,KTH-U1272S,KTH-U1282S,KTH-U1292S,KTH-U2162S,KTH-U2172S,KTH-U2182S,KTH-U2192S,KTH-U3162S,KTH-U3172S,KTH-U3182S,KTH-U3192S,KTH-U3262S,KTH-U3272S,KTH-U3282S,KTH-U3292S,KTH-U4162S,KTH-U4172S,KTH-U4182S,KTH-U4192S,KTH-U4262S,KTH-U4272S,KTH-U4282S,KTH-U4292S,KTH-U4362S,KTH-U4372S,KTH-U4382S,KTH-U4392S,KTH-B1161S,KTH-B1162S,KTH-B1171S,KTH-B1172S,KTH-B1181S,KTH-B1182S,KTH-B1191S,KTH-B1192S,KTH-B1261S,KTH-B1262S,KTH-B1271S,KTH-B1272S,KTH-B1281S,KTH-B1282S,KTH-B1291S,KTH-B1292S,KTH-B2161S,KTH-B2162S,KTH-B2171S,KTH-B2172S,KTH-B2181S,KTH-B2182S,KTH-B2191S,KTH-B2192S,KTH-B3161S,KTH-B3162S,KTH-B3171S,KTH-B3172S,KTH-B3181S,KTH-B3182S,KTH-B3191S,KTH-B3192S,KTH-B3261S,KTH-B3262S,KTH-B3271S,KTH-B3272S,KTH-B3281S,KTH-B3282S,KTH-B3291S,KTH-B3292S,KTH-B4161S,KTH-B4162S,KSP-1161,KSP-1162,KSP-1171,KSP-1172,KSP-1181,KSP-1182,KSP-1191,KSP-1192,KSP-2161,KSP-2162,KSP-2171,KSP-2172,KSP-2181,KSP-2182,KSP-2191,KSP-2192,KDX-AC,KDX-AN,KDX-BC,KDX-B2N,KDX-B1N,KDX-A1N,KDX-A1C,韓國電材K120-380V4Y,120kA,3P,380V,4W,320V型號齊全
