韓國(guó)光星KTA-171A1S,KTA-171A2S,KTA-171A2T,質(zhì)量怎么樣　?。嚎撮T狗有兩個(gè)重要信 ：時(shí)鐘輸入和復(fù)位輸出。電路工作時(shí)，CPU送出時(shí)鐘信 給看門狗，即喂狗。如果系統(tǒng)出現(xiàn)故障，CPU無(wú)法送出連續(xù)的時(shí)鐘信 ，看門狗即輸出復(fù)位信 給CPU，復(fù)位系統(tǒng)。28、請(qǐng)列舉三種典型的ESD模型。：模型（HBM）、機(jī)器模型（MM）、帶電器件模型（CDM）。　　但是，由于不同的汽車音響安裝位置的限制，低音炮單元通常只能在行李艙安裝，低音一般單位只能在車前安裝，高音單元通常安裝在A柱附近。這種影響可能只是來(lái)聽(tīng)取了高音和低音從后面來(lái)同月比較，奧拓部分相對(duì)薄弱。此外，針對(duì)不同的模塊和功率放大的要求，在一般汽車音響只能采取多種放大器驅(qū)動(dòng)揚(yáng)聲器（許多設(shè)計(jì)的低頻部分需要由多個(gè)放大器放大），因此音調(diào)平衡是很難達(dá)到令人滿意的水平。
　　中間繼電器實(shí)際是一個(gè)觸頭容量較大、觸頭數(shù)目較多的電壓繼電器，一般用于各種保護(hù)和自動(dòng)控制裝置中，作為輔助繼電器，以增加保護(hù)和控制回路的接點(diǎn)數(shù)量和接點(diǎn)容量。常用的中間繼電器型 有DZ—10、DZ—30、DZB—10、DZS—100、DZ—200、ZJ1～JZ4等。

 　　二、自耦變壓器降壓起動(dòng)控制線路自耦變壓器降壓起動(dòng)是指電動(dòng)機(jī)起動(dòng)時(shí)利用自耦變壓器來(lái)降低加在電動(dòng)機(jī)定子繞組上的起動(dòng)電壓。待電動(dòng)機(jī)起動(dòng)后，再將自耦變壓器脫離，使電動(dòng)機(jī)在全壓下正常運(yùn)行。三、星形——三角形降壓起動(dòng)控制線路星形——三角形（Y—△）降壓起動(dòng)是指電動(dòng)機(jī)起動(dòng)時(shí)，把定子繞組接成星形，以降低起動(dòng)電壓，減小起動(dòng)電流；待電動(dòng)機(jī)起動(dòng)后，再把定子繞組改接成三角形，使電動(dòng)機(jī)全壓運(yùn)行。

　　采用萬(wàn)用表檢測(cè)揚(yáng)聲器也是粗略的。測(cè)量直流電阻：用R*1檔測(cè)量揚(yáng)聲器兩引腳之間的直流電阻，正常時(shí)應(yīng)比銘牌揚(yáng)聲器阻抗略小。例如8歐姆的揚(yáng)聲器測(cè)量的電阻正常為7歐姆左右。測(cè)量阻值為無(wú)窮大，或遠(yuǎn)大于它的標(biāo)稱阻抗值，說(shuō)明揚(yáng)聲器已經(jīng)損壞。

 　　差動(dòng)式斷相保護(hù)裝置結(jié)構(gòu)原理如圖3所示。熱繼電器的導(dǎo)板改為差動(dòng)機(jī)構(gòu)，由上導(dǎo)板1、下導(dǎo)板2及杠桿5組成，它們之間都用轉(zhuǎn)軸連接。圖3a為通電前機(jī)構(gòu)各部件的位置。圖3b為正常通電時(shí)的位置，此時(shí)三相雙金屬片都受熱向左彎曲，但彎曲的撓度不夠，所以下導(dǎo)板向左移動(dòng)一小段距離，繼電器不動(dòng)作。
