Description
Предметом насто щего изобретени вл етс способ отыскани при иомощи кабелеискател места обрыва кабел одной или жил в подземной кабельной линии, с неметаллической , например, полихлорвиниловой оболочкой.The object of the present invention is a method for finding with the help of a cable detector a place of cable breakage alone or lived in an underground cable line with a non-metallic, for example, PVC jacket.
В насто щее врем известны способы отыскани места обрыва жил кабел при помощи кабелеискател и одиночного генератора звуковой частоты, подключаемого к одному концу поврежденной жилы. Однако эти способы не дают прн поисках уверенных результатов в отношении точности определени места обрыва.Nowadays, methods are known for finding a cable breakage using a cable detector and a single audio frequency generator connected to one end of a damaged core. However, these methods do not provide a search for reliable results with respect to the accuracy of determining the location of the cliff.
В насто щем изобретении предлагаетс способ отыскани места обрыва при помощи кабелеискател , отличающийс от известных способов тем, что питание поврежденной жилы кабел осуществл етс не одним, а двум генераторами различных тональных частот.The present invention proposes a method for locating a break point using a cable detector, different from the known methods in that the damaged cable core is powered not by one, but by two generators of different tonal frequencies.
подключаемыми однопременпо с обоих концов ненснравно жилы кабел одним полюсом к земле, а вторым - к нсиле кабел .connectable at one end with both ends of the cable at one end to the ground, and the second - to the force of the cable.
Место обрыва жилы кабел определ етс при движении кабелеискател на слух, по по влению в его телефонных трубках вместо тона первого генератора,- тона второго генератора тональпоГ частоты .The place where a cable core is broken is determined by hearing when the cable detector is moving by ear, it appears in its handsets, instead of the tone of the first generator, the tone of the second tone frequency generator.
Предмет изобретен и The subject is invented and
Способ отысканг1Я места обрыва жилы подземного кабел с неметаллической (полнхлорвиниловои) оболочкой, основанньп иа применении кабелеискател , о т л и м а ющ и и с тем, что, с целью повышени точности определени места повреждени , используютс два генератора различных тональных частот, которые подключаютс одновременно с обоих концов непсnpaBHOii жилы кабел и к земле.The method of finding the place of a broken wire of an underground cable with a non-metallic (full vinyl chloride) sheath, based on the use of a cable detector, is made so that, in order to improve the accuracy of determining the place of damage, two different tonal frequency generators are used at the same time at both ends of the cable nepnpaBHOii cable and to the ground.
