進行分析電路關鍵技術任務關鍵技術二、進行檢查層面步湊及步驟1 ．外觀專利檢修1) 診斷是不是絕緣電阻電阻層壓入接電源接線頭鼻子，如果發現絕緣電阻電阻層壓入接電源接線頭鼻子，通電后，會使三極管是沒辦法接聽電話。

2) 檢查裸露的導(dao)(dao)線線芯是否(fou)符合(he)規(gui)定。3)用手搖動(dong)、拉(la)撥接線端子上的導(dao)(dao)線。檢查所有導(dao)(dao)線與端子的接處現(xian)狀，不(bu)不(bu)可以有滑牙。 4)用萬用表(biao)定期檢查各(ge)組(zu)件的動(dong)作(zuo)現(xian)狀及接法(fa)是否(fou)是對(dui)的。

2 ．主電路系統的定期檢查

用(yong)(yong)萬用(yong)(yong)表(biao)(biao)： RxlO 擋或 R × 100 擋，將(jiang)兩表(biao)(biao)筆分別接在圖中(zhong) 6 與 U 、 7 與 V 、 8 與W兩點互相。正常的現(xian)狀萬用(yong)(yong)表(biao)(biao)游針此刻(ke)應對應指在“∞”角度。接下來，側量(liang)點變了，清理溝(gou)通(tong)交流(liu)(liu)(liu)沾染器KM1 、KM2，這段時間，若萬用(yong)(yong)表(biao)(biao)游針從無窮大定位(wei)向下偏轉，解釋交流(liu)(liu)(liu)活(huo)動了解器過程好的且主(zhu)用(yong)(yong)電線路交流(liu)(liu)(liu)使用(yong)(yong)器主(zhu)接觸點及(ji)熱繼(ji)物(wu)品熱電子器件(jian)接法有效且情形(xing)正常的。

3 ．把控電路板的檢測1) 進行檢查開關的瑜伽動作及布線原因。用萬用表 R × 10 擋或 R × 100 擋，將兩表筆各自接在圖內

1 、5兩點。正(zheng)常情況萬(wan)(wan)(wan)用(yong)(yong)表(biao)(biao)(biao)指(zhi)(zhi)針(zhen)(zhen)(zhen)(zhen)此(ci)時應指(zhi)(zhi)在“∞”位(wei)置。萬(wan)(wan)(wan)用(yong)(yong)表(biao)(biao)(biao)指(zhi)(zhi)針(zhen)(zhen)(zhen)(zhen)指(zhi)(zhi)示正(zheng)常后，按下按鈕SB1 ，若(ruo)萬(wan)(wan)(wan)用(yong)(yong)表(biao)(biao)(biao)游針(zhen)(zhen)(zhen)(zhen)向下偏(pian)轉(zhuan)，就說明圖標(biao)SB1接(jie)線(xian)(xian)(xian)圖正(zheng)確無(wu)誤且(qie)拉伸動作正(zheng)常，彈起來圖標(biao) SB1 。這(zhe)時萬(wan)(wan)(wan)用(yong)(yong)表(biao)(biao)(biao)指(zhi)(zhi)南應又(you)趕回“∞”部(bu)位(wei)．萬(wan)(wan)(wan)用(yong)(yong)表(biao)(biao)(biao)指(zhi)(zhi)示器(qi)的(de)(de)熱(re)敏(min)電(dian)(dian)阻(zu)(zu)功率參考值(zhi)交流(liu)活動電(dian)(dian)碰(peng)到器(qi)熱(re)敏(min)電(dian)(dian)阻(zu)(zu)線(xian)(xian)(xian)的(de)(de)直(zhi)流(liu)電(dian)(dian)壓熱(re)敏(min)電(dian)(dian)阻(zu)(zu)功率 (交流(liu)活動電(dian)(dian)碰(peng)到器(qi)KMl 、 KM 型(xing)號(hao)規格差不多 ) 。再(zai)輕(qing)(qing)按快(kuai)捷(jie)(jie) SB2 ，若(ruo)萬(wan)(wan)(wan)用(yong)(yong)表(biao)(biao)(biao)指(zhi)(zhi)示針(zhen)(zhen)(zhen)(zhen)向左偏(pian)轉(zhuan)，表(biao)(biao)(biao)明快(kuai)捷(jie)(jie) SB2 接(jie)法對的(de)(de)且(qie)動做優質，松(song)掉(diao)按鍵SB2，于此(ci)萬(wan)(wan)(wan)用(yong)(yong)表(biao)(biao)(biao)游針(zhen)(zhen)(zhen)(zhen)又(you)回來“∞”區(qu)域。再(zai)輕(qing)(qing)按按鍵 SB1( 或SB2)，萬(wan)(wan)(wan)用(yong)(yong)表(biao)(biao)(biao)指(zhi)(zhi)南往右(you)邊偏(pian)轉(zhuan)，萬(wan)(wan)(wan)用(yong)(yong)表(biao)(biao)(biao)指(zhi)(zhi)示器(qi)的(de)(de)內阻(zu)(zu)數值(zhi)為溝通使用(yong)(yong)器(qi)次級線(xian)(xian)(xian)圈的(de)(de)交流(liu)電(dian)(dian)內阻(zu)(zu)。然而(er)再(zai)不放下去(qu) SB1( 或SB2) 的(de)(de)情形下。按壓SB3，若(ruo)萬(wan)(wan)(wan)用(yong)(yong)表(biao)(biao)(biao)表(biao)(biao)(biao)針(zhen)(zhen)(zhen)(zhen)從右(you)偏(pian)“∞”位(wei)置上，表(biao)(biao)(biao)明快(kuai)捷(jie)(jie) SB3 布線(xian)(xian)(xian)最佳(jia)且(qie)能(neng)穩(wen)定斷掉(diao)操縱電(dian)(dian)源線(xian)(xian)(xian)路。 2) 查(cha)自鎖(suo)部(bu)門。用(yong)(yong)萬(wan)(wan)(wan)用(yong)(yong)表(biao)(biao)(biao) R × 10擋(dang)或R × 100 擋(dang)，將兩表(biao)(biao)(biao)筆(bi)分(fen)別接(jie)在圖里

2 、5兩(liang)點，正常情況萬(wan)用(yong)表(biao)(biao)指針(zhen)此時應指在“∞”位置(zhi)。萬(wan)用(yong)表(biao)(biao)指針(zhen)指示(shi)(shi)正常后，手(shou)動(dong)交(jiao)(jiao)流接(jie)觸器(qi)(qi)KM1，若萬(wan)用(yong)表(biao)(biao)游標往右(you)邊偏轉，代(dai)表(biao)(biao)自(zi)(zi)鎖輔助(zhu)制作(zuo)動(dong)合(he)接(jie)線柱(zhu)柱(zhu) KM1接(jie)線柱(zhu)正規且動(dong)作(zuo)優質(zhi)．萬(wan)用(yong)表(biao)(biao)的指示(shi)(shi)的內阻指標值交(jiao)(jiao)談學習(xi)(xi)沾染器(qi)(qi)電(dian)感的直流變壓器(qi)(qi)內阻。第二(er)步，放下去(qu)交(jiao)(jiao)談學習(xi)(xi)沾染器(qi)(qi) KM1．使萬(wan)用(yong)表(biao)(biao)游標進入“∞”位子。再手(shou)動(dong)式聊天排斥器(qi)(qi) KM2 ，若萬(wan)用(yong)表(biao)(biao)指南向(xiang)左向(xiang)右(you)偏轉，就說(shuo)明自(zi)(zi)鎖鋪助(zhu)動(dong)合(he)連(lian)接(jie)線柱(zhu)KM2連(lian)接(jie)線合(he)適且小動(dong)作(zuo)比較好(hao)。

4 ．體檢互鎖關鍵環節

1) 動斷互鎖輔助(zhu)觸(chu)點(dian) KM1 。用(yong)(yong)萬(wan)(wan)用(yong)(yong)表(biao) R × 10 擋或 R × 100 擋，將兩表(biao)筆分別接(jie)在(zai)圖中 4 、5這兩點(dian)，正常人現狀萬(wan)(wan)用(yong)(yong)表(biao)游(you)針(zhen)應(ying)由“∞”位(wei)子向左偏轉。萬(wan)(wan)用(yong)(yong)表(biao)顯示的電阻功率指標(biao)值溝通(tong)交流(liu)了解器 KM2感應(ying)線圈的直流(liu)電阻值，那么．半自動交流(liu)溝通(tong)接(jie)處器KM1。若萬(wan)(wan)用(yong)(yong)表(biao)游(you)針(zhen)又(you)喜(xi)愛(ai)“∞”地址。原(yuan)因分析動斷互鎖氧化硅接(jie)點(dian) KM1 連接(jie)線正確合理且(qie)運(yun)行積極(ji)。

2) 動斷互(hu)鎖輔(fu)助(zhu)觸點 KM2 。用萬(wan)用表(biao)(biao)R ×10 擋或 R × 100 擋。將兩表(biao)(biao)筆分別接(jie)在(zai)圖中 3 、 5兩個方面，正常狀(zhuang)態狀(zhuang)態萬(wan)用表(biao)(biao)游(you)針應由“∞”地位(wei)(wei)向左向右偏轉。萬(wan)用表(biao)(biao)顯示燈的(de)熱敏電阻臨界(jie)值交談接(jie)受器KM1線圈的(de)聯(lian)席(xi)會電電阻功(gong)率，最(zui)后，速騰自動檔(dang)聯(lian)席(xi)會接(jie)觸到器 KM2 。若萬(wan)用表(biao)(biao)游(you)標(biao)又傾向“∞”位(wei)(wei)址(zhi)，代表(biao)(biao)動斷互(hu)鎖輔(fu)助(zhu)觸點開關KM2接(jie)法規范且行為比較好。

依據以上所述哪步．就可常規檢查出控制線路的連接線及控制線路各電子器件的總體的情況，這種，就可通電試運了
