江蘇春晨電纜有限公司生產YGCB扁電纜，常見問題：

Common problem:

1、錯用接觸器的觸點，把輔助觸點當成主觸點使用。這是沒有注意看清楚（或不懂）接觸器的結構和接線端子位置之間關系造成的；

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、漏接常開自鎖觸點，也就是沒有自鎖功能；

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，沒有過載保護功能。有些人則在熱繼電器接吸引線圈處借線作自鎖，結果把熱繼電器的常閉觸點也串進去了，失去過載保護功能；

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熱繼電器常閉觸點回到電源，漏接啟動按鈕；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按鈕之間串入吸引線圈，(/ 電工之家)這樣做不符合常規的安裝工藝要求，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按鈕兩端，以為是接在常開自鎖觸點上了；

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、停止按鈕與啟動按鈕之間沒有連接線，兩者沒有達到串連關系，造成無法啟動。有些學員甚至將啟動按鈕短接了，造成通電就啟動，無法停機現象；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/停止按鈕混淆，沒有根據按鈕顏色去區分哪個是啟動按鈕，哪個是停止按鈕；

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）線，或者在有條件時沒有采用黃綠雙（或單黃）色線，這也是最經常見到的毛病；

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、控制電路沒有接入熔斷器，或者電源沒有接入熔電器；

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

11、主電路沒有接入熱繼電器主接線端子，失去過載保護功能。或者進線端和出線端顛倒；

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）開關或斷路器、接觸器之一主電路沒有接線，沒完成考核。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.
