江蘇春晨電纜有限公司生產(chǎn)YGCB扁電纜，常見(jiàn)問(wèn)題：

Common problem:

1、錯(cuò)用接觸器的觸點(diǎn)，把輔助觸點(diǎn)當(dāng)成主觸點(diǎn)使用。這是沒(méi)有注意看清楚（或不懂）接觸器的結(jié)構(gòu)和接線端子位置之間關(guān)系造成的；

1, misuse contacts of contactors and use auxiliary contacts as main contacts. This is caused by the relationship between the structure of the contactor and the location of the terminals.

2、漏接常開(kāi)自鎖觸點(diǎn)，也就是沒(méi)有自鎖功能；

2, the leakage often opens the self locking contact, that is, there is no self-locking function.

3、漏接熱繼電器常閉觸點(diǎn)，沒(méi)有過(guò)載保護(hù)功能。有些人則在熱繼電器接吸引線圈處借線作自鎖，結(jié)果把熱繼電器的常閉觸點(diǎn)也串進(jìn)去了，失去過(guò)載保護(hù)功能；

3, leakage of thermal relay normally closed contacts, no overload protection function. Some people use the wire at the suction coil to self lock in the thermal relay, and the result is that the normally closed contacts of the thermal relay are also strung in, and the overload protection function is lost.

4、停止按鈕直接接接觸器吸引線圈后通過(guò)熱繼電器常閉觸點(diǎn)回到電源，漏接啟動(dòng)按鈕；4. The stop button directly contacts the contactor to attract the coil and then returns to the power supply through the normally closed contact of the thermal relay, and the button is missed.

5、有些則在停止按鈕和啟動(dòng)按鈕之間串入吸引線圈，(/ 電工之家)這樣做不符合常規(guī)的安裝工藝要求，存在隱患，仍判為不合格；YGCB扁電纜3*35+2*35*2*16

5, some in the stop button and start button string into the attraction coil, (/ electrician's home) do not meet the conventional installation process requirements, there is a safety hazard, still judged to be unqualified;

6、接觸器吸引線圈并在啟動(dòng)按鈕兩端，以為是接在常開(kāi)自鎖觸點(diǎn)上了；

6, the contactor attracts the coil and ends at the start button, which is thought to be connected to the normally open self locking contact.

7、停止按鈕與啟動(dòng)按鈕之間沒(méi)有連接線，兩者沒(méi)有達(dá)到串連關(guān)系，造成無(wú)法啟動(dòng)。有些學(xué)員甚至將啟動(dòng)按鈕短接了，造成通電就啟動(dòng)，無(wú)法停機(jī)現(xiàn)象；YGCB扁電纜3*35+2*35*2*16

7, there is no connecting line between the stop button and the start button, and the two have not reached the serial connection, resulting in failure to start. Some students will even start the short button, causing the power to start and stop the machine.8、啟動(dòng)/停止按鈕混淆，沒(méi)有根據(jù)按鈕顏色去區(qū)分哪個(gè)是啟動(dòng)按鈕，哪個(gè)是停止按鈕；

8, the start / stop button is confused. It does not distinguish between the start button and the stop button according to the button color.

9、漏接PE（保護(hù)）線，或者在有條件時(shí)沒(méi)有采用黃綠雙（或單黃）色線，這也是最經(jīng)常見(jiàn)到的毛??；

9, the PE (safety protection) line is missing, or the yellow green double (or single yellow) color line is not used when conditions are available. This is also the most common problem.

10、控制電路沒(méi)有接入熔斷器，或者電源沒(méi)有接入熔電器；

10, the control circuit is not connected to fuses, or the power supply is not connected to the fuse.

11、主電路沒(méi)有接入熱繼電器主接線端子，失去過(guò)載保護(hù)功能?；蛘哌M(jìn)線端和出線端顛倒；

11. The main circuit is not connected with the main connection terminal of the thermal relay, and the overload protection function is lost. Either the end of the line and the end of the line are reversed.

12、隔離（閘刀）開(kāi)關(guān)或斷路器、接觸器之一主電路沒(méi)有接線，沒(méi)完成考核。YGCB扁電纜3*35+2*35*2*16

12, isolation (switch) switch or circuit breaker, contactor one of the main circuit is not wiring, did not complete the examination.
