EV-S90U充电桩电缆

自从人们开始发现使用电时，电线和电缆就成为了电力传输的主要载体。无论是电器设备、照明线路还是家用电器方方面面都离不开电线电缆。它虽然只是一个配套行业，但却占据着电工行业的大半个市场。电线电缆的好坏会直接影响到工程的质量和人们的安全，也会影响到电缆的发展前景。EV-S90U充电桩电缆

Since people began to find the use of electricity, wires and cables have become the main carrier of power transmission. Whether it is electrical equipment, lighting or household appliances can not be separated from all aspects of wire and cable. Although it is only a supporting industry, but it occupies more than half of the electrical industry market. The quality of wire and cable will directly affect the quality of the project and the safety of the people, but also affect the development prospects of the cable.

电线电缆在运行的过程中，经常会出现这样那样的事故，尤其是使用了非标电线电缆的情况下。电缆在运行时，发生两相（及多相）接地或相间短路故障时，大多造成系统跳闸，这种故障现象俗称--放炮。下面我们就来说说，造成"电缆放炮"的主要因素有哪些呢？EV-S90U充电桩电缆

Wire and cable in the process of running, there will always be such an accident, especially the use of non-standard wire and cable case. When the cable is running, the two phase (and multi-phase) grounding or interphase short-circuit fault, most of which cause the system trip, which is commonly known as the phenomenon of blasting. Let us talk about the following, resulting in "cable blasting" the main factors which?

1、电缆内部三相芯线发生互相之间的短路故障、或者其中一相对电缆外皮短路故障，都会产生非常大的热量，使得故障处爆裂。EV-S90U充电桩电缆

1, the cable internal three-phase line between the short-circuit fault occurs, or one of the cable sheath short-circuit fault, will produce a very large amount of heat, so that the failure of the burst.

2、比如绝缘层内颗粒、杂质、气泡之类，或者是有外部机械损伤。

2, such as the insulation layer of particles, impurities, bubbles, or external mechanical damage.

3、检查电缆是否弯曲太很把电缆给伤了。

3, check whether the cable is too bent cable damage.

4、弯曲半径太小，机械外力损伤，直流电阻试验离子释放未尽，额定电流过载。

4, the bending radius is too small, mechanical damage, DC resistance test ion release is not enough, rated current overload.

电缆放炮都是在运行中发生的，会造成系统突然跳闸，这对生产极其的不利。我们认为电缆系统如果经常出现放炮故障，说明电缆线路的施工、运行、维护和管理等环节中存在较大的问题，应引起足够的重视，在抢修工作完成以后，应当认真查找原因并加以消除，避免再次发生放炮事故

The blasting of the cable is in operation, which will cause the system to trip suddenly, which is extremely harmful to the production. We believe that if the cable system often blasting fault, there is a big problem that link cable line construction, operation, maintenance and management, should cause enough attention, after the repair work is completed, should seriously find out the reasons and to eliminate, avoid blasting accidents happen again
