With the rapid development of China's economy, the cable industry has also been a huge development. Cable based on the use of the performance of different kinds of cables, computer cables, flame retardant cables, control cables, such as more than one hundred kinds of cables. In the past few decades, China's cable industry the formation of productive force, let the world sit up and take notice. In China's electric power industry, rail transportation, data communication industry, auto industry and mine industry continues to expand the scale of cable demand also is in rapid growth, the cable industry has a lot of space will develop in the future. Cable in the use of the time there may be some failures, such as cable breakdown, cable conductor damage, broken core and some other failures. Flame retardant cable conductor in the cross section area is small, to be broken when the cable, in the process of extrusion molding in production. So how to check the flame retardant cable break it?
一：通电电容的方法，JEM电机引接线
Method of electric capacity
一些电缆厂在这方面的做法通常是用电容的比较法来，查找断线的大概位置。用连续通电的方式来准确的电缆的断线点，这种方式的效率是很低的。一般查找一个断线点要1个半小时左右。这种方法对屏蔽、铠装、护套工序已经完成的阻燃电缆来说，几乎不可能找到断芯，造作不良的话还会使阻燃电缆报废。这种方法现在基本上已经不用了。JEM电机引接线
Some cable plants in this area are usually used to compare the capacitance of the method, to find the location of the broken line. The efficiency of this method is very low in the way of using the power of the cable to correct the breaking point of the cable. Generally find a break point to 1.5 hours or so. This method has been completed on the shield, armor, flame retardant cable sheath process is almost impossible to find a broken core, it will make bad things of flame retardant cable scrap. This method is now basically no longer.
二：电容法和感应法相结合：JEM电机引接线
Two: the combination of capacitance and induction:
这种方法是使用于缆芯的断芯，这就要求缆芯外没有包覆金属层且没有挤包护层。在查找的时候先用电容找出电缆断线的大致位置，然后用感应电压法在精确的查找断线点，这种方法是很简单快捷的，也是目前使用zui多的一种方法。感应电压法是在电缆的断芯的一端接650V的交流电压，另一端及其它芯子接地，然后用可发以光信号的感应笔进行测试，测试时当感应笔从断芯处滑过时，信号会发生变化，这样可以精确地查找到电缆断线点的。
This method is used in the core of the cable core, which requires that there is no metal layer outside the cable core and there is no extrusion cladding. In finding the time to find the first with the capacitance to find the approximate location of the cable line, and then use the induction voltage method to accuray find the break point, this method is very simple and fast, but also the most widely used method. The induction voltage method is AC voltage 650V in the broken end of the cable, the other end and other core grounding, then can send a signal light induction pen test, test when the induction pen from the broken core slide out of date, signal will change, so you can accuray find cable break point the.
三：恒流源和电桥法相结合
Three: the combination of constant current source and bridge method
这种方法是用于完成的电缆或已包覆金属层的缆芯。使用是查找的方法是先用恒流源将阻燃电缆的断芯处的绝缘烧糊、击穿，然后在用电桥法故障定位仪精确的定位故障点，也是经常使用的一种方法
This method is used for the completion of a cable or a cable core that has been coated with a metal layer. Use is to find the method is to use a constant current source will be flame retardant cable off the core of the insulation burn paste, breakdown, and then use the bridge method fault locator accurate location of the fault point, is often used in a way
