韓國(guó)京甫DM3N-DA21,DM3N-DA22,品質(zhì)可以信任! 每一只揚(yáng)聲器只能較好地重放音頻的某一部分。4、失真揚(yáng)聲器不能把原來(lái)的聲音逼真地重放出來(lái)的現(xiàn)象叫失真。失真有兩種：頻率失真和非線性失真。頻率失真是由于對(duì)某些頻率的信號(hào)放音較強(qiáng)，而對(duì)另一些頻率的信號(hào)放音較弱造成的，失真破壞了原來(lái)高低音響度的比例，改變了原聲音色�！ �(duì)于三角形接法的電動(dòng)機(jī)，熱元件接在主電路什么位置呢。對(duì)于Δ形接法的電動(dòng)機(jī)，其相斷線時(shí)，流過(guò)未斷相繞組的電流與流過(guò)熱繼電器的電流增加比例則不同。也就是說(shuō)，流過(guò)熱繼電器的電流不能反映斷相后繞組的過(guò)載電流。所以，必須將三相結(jié)構(gòu)熱繼電器的三個(gè)元件分別與電動(dòng)機(jī)每相繞組的串聯(lián)。
而且越是經(jīng)歷過(guò)維修多的電動(dòng)機(jī)，其運(yùn)行使用壽命縮水則更為明顯。那么到底是什么原因造成這種情況的發(fā)生哪。在排除上述嵌線工藝、裝配工藝、甚至是漆包銅線的質(zhì)量問(wèn)題外，我們不難發(fā)現(xiàn)問(wèn)題的癥結(jié)所在——舊繞組拆除工序當(dāng)中是否考慮到溫度因素的影響。
根據(jù)同心式繞組的畫法，我們得出個(gè)N極和第二個(gè)S極的1------8槽（y=7)、2------7槽(y=5)相連的二個(gè)繞組，而第三個(gè)N極與第四個(gè)S極的連接與上面是相同的，分別是13------20、14------19相連，同樣組成另二個(gè)繞組。這樣A相繞組全部畫完（畫時(shí)應(yīng)逆時(shí)針?lè)较颍！ ?dòng)生電動(dòng)勢(shì)的來(lái)源:如圖，運(yùn)動(dòng)導(dǎo)每個(gè)電子受到方向向上的洛侖茲力為：；正負(fù)電荷積累在導(dǎo)建立電場(chǎng)；當(dāng)時(shí)達(dá)到動(dòng)態(tài)平衡，不再有宏觀定向運(yùn)動(dòng)，則導(dǎo)體ab相當(dāng)一個(gè)電源，a為負(fù)極（低電勢(shì)），b為正極（高電勢(shì)），洛侖茲力就是非靜電力。

帶的二次繞組自身分為兩個(gè)不同變比和不同準(zhǔn)確度等級(jí)的繞組，隨著一次繞組連接片位置的變更，一次繞組匝數(shù)相應(yīng)改變，其變比也隨之改變，這樣就形成了多量程的變比。帶的二次繞組的不同變比和不同準(zhǔn)確度等級(jí)，可以分別應(yīng)用于電能計(jì)量、指示儀表、變送器、繼電保護(hù)等，以滿足各自不同的使用要求�！ 〔⒔ㄗh10kV側(cè)電容器組分組容量確定為2000、3000、6000kvar。（2）對(duì)于普通負(fù)荷的公用變的0.4kV低壓補(bǔ)償，可按配變?nèi)萘康?0%～30%進(jìn)行補(bǔ)償。（3）當(dāng)三相電壓不平衡時(shí)（如單相負(fù)荷較多），需考慮一定容量的分相補(bǔ)償。（4）對(duì)于企業(yè)變壓器的0.4kV低壓補(bǔ)償，可按配變?nèi)萘康?0%～60%進(jìn)行補(bǔ)償。
