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：通電電容的方法，JEM電機(jī)引接線

Method of electric capacity

一些電纜廠在這方面的做法通常是用電容的比較法來(lái)，查找斷線的大概位置。用連續(xù)通電的方式來(lái)準(zhǔn)確的電纜的斷線點(diǎn)，這種方式的效率是很低的。一般查找一個(gè)斷線點(diǎn)要1個(gè)半小時(shí)左右。這種方法對(duì)屏蔽、鎧裝、護(hù)套工序已經(jīng)完成的阻燃電纜來(lái)說(shuō)，幾乎不可能找到斷芯，造作不良的話還會(huì)使阻燃電纜報(bào)廢。這種方法現(xiàn)在基本上已經(jīng)不用了。JEM電機(jī)引接線

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：電容法和感應(yīng)法相結(jié)合：JEM電機(jī)引接線

Two: the combination of capacitance and induction:

這種方法是使用于纜芯的斷芯，這就要求纜芯外沒(méi)有包覆金屬層且沒(méi)有擠包護(hù)層。在查找的時(shí)候先用電容找出電纜斷線的大致位置，然后用感應(yīng)電壓法在精確的查找斷線點(diǎn)，這種方法是很簡(jiǎn)單快捷的，也是目前使用zui多的一種方法。感應(yīng)電壓法是在電纜的斷芯的一端接650V的交流電壓，另一端及其它芯子接地，然后用可發(fā)以光信號(hào)的感應(yīng)筆進(jìn)行測(cè)試，測(cè)試時(shí)當(dāng)感應(yīng)筆從斷芯處滑過(guò)時(shí)，信號(hào)會(huì)發(fā)生變化，這樣可以精確地查找到電纜斷線點(diǎn)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：恒流源和電橋法相結(jié)合

Three: the combination of constant current source and bridge method

這種方法是用于完成的電纜或已包覆金屬層的纜芯。使用是查找的方法是先用恒流源將阻燃電纜的斷芯處的絕緣燒糊、擊穿，然后在用電橋法故障定位儀精確的定位故障點(diǎn)，也是經(jīng)常使用的一種方法

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
