江苏春晨电缆有限公司生产YGCB扁电缆，常见问题：

Common problem:

1、错用接触器的触点，把辅助触点当成主触点使用。这是没有注意看清楚（或不懂）接触器的结构和接线端子位置之间关系造成的；

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、漏接常开自锁触点，也就是没有自锁功能；

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

3、漏接热继电器常闭触点，没有过载保护功能。有些人则在热继电器接吸引线圈处借线作自锁，结果把热继电器的常闭触点也串进去了，失去过载保护功能；

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、停止按钮直接接接触器吸引线圈后通过热继电器常闭触点回到电源，漏接启动按钮；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、有些则在停止按钮和启动按钮之间串入吸引线圈，(/ 电工之家)这样做不符合常规的安装工艺要求，存在隐患，仍判为不合格；YGCB扁电缆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、接触器吸引线圈并在启动按钮两端，以为是接在常开自锁触点上了；

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、停止按钮与启动按钮之间没有连接线，两者没有达到串连关系，造成无法启动。有些学员甚至将启动按钮短接了，造成通电就启动，无法停机现象；YGCB扁电缆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、启动/停止按钮混淆，没有根据按钮颜色去区分哪个是启动按钮，哪个是停止按钮；

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（保护）线，或者在有条件时没有采用黄绿双（或单黄）色线，这也是经常见到的毛病；

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、控制电路没有接入熔断器，或者电源没有接入熔电器；

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

11、主电路没有接入热继电器主接线端子，失去过载保护功能。或者进线端和出线端颠倒；

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、隔离（闸刀）开关或断路器、接触器之一主电路没有接线，没完成考核。YGCB扁电缆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.
