Abstract
Сущность изобретени : всю поверхность трубопровода (ТП) 2 охватывают электропроводники (ЭП) 3, проложенные между изол ционными сло ми 1 вдоль ТП 2. Концы ЭП 3 выведены за пределы изол ции. Многожильный кабель 4 проложен вдоль ТП 2, к каждой паре жил которого подсоединены ЭП 3 каждого участка ТП 2. Свободные концы кабел 4 выведены на контрольный щит. смонтированный в магистральной камере . 2 ил.The essence of the invention: the entire surface of the pipeline (TP) 2 covers the electrical conductors (EP) 3, laid between the insulating layers 1 along the TP 2. The ends of the EP 3 are out of isolation. The multicore cable 4 is laid along the TP 2, to each pair of the veins of which are connected the EP 3 of each section of the TP 2. The free ends of the cable 4 are brought to the control board. mounted in the main chamber. 2 Il.
Description
Изобретение относитс к технике контрол за состо нием наружной поверхности подземного трубопровода, подвергающегос коррозии под воздействием окружающей среды.The invention relates to a technique for monitoring the state of the outer surface of an underground pipeline, which is exposed to corrosion under the influence of the environment.
Цель изобретени - расширение функциональных возможностей устройства путем определени мест повреждений состо щего из отдельных участков трубопровода в начальной стадии их возникновени .The purpose of the invention is to expand the functionality of the device by determining the locations of damage consisting of individual sections of the pipeline in the initial stage of their occurrence.
На фиг. 1 представлена схема предлагаемого устройства; на фиг. 2 - сечение А-А на фиг. 1.FIG. 1 shows the scheme of the proposed device; in fig. 2 is a section A-A in FIG. one.
В изол ционном слое 1 трубопровода 2, состо щего из отдельных участков, проложен электропроводник 3. На каждом участке трубопровода концы электропроводников выведены и подсоединены к многожильному кабелю 4, пары жил которого подключены последовательно к электро- проводникам 3 каждого пронумерованного участка трубопровода.In the insulating layer 1 of pipeline 2, consisting of separate sections, an electrical conductor 3 is laid. In each pipeline section, the ends of the electrical conductors are brought out and connected to the multicore cable 4, whose pairs of veins are connected in series to the electrical conductors 3 of each numbered pipeline section.
В магистральной камере 5 смонтирован контрольный щит 6, к клеммам которого подсоединены электропроводники 3 трубопровода 2.In the main chamber 5 mounted control panel 6, to the terminals of which are connected the electrical conductors 3 of the pipeline 2.
Устройство работает следующим образом .The device works as follows.
Дл определени места повреждени поверхности трубопровода подключают тестер к клеммам, к которым выведены электропроводники . Если разрыва цепи нет, то цепь замкнута и стрелка тестера отклон етс , если же цепь разорвана, т.е поврежден электропроводник и изол ци на трубопроводе , то стрелка тестера не отклон етс , остаетс на нуле. Кроме того, разрыв цепи можно определить, если подавать электрический ток на каждый участок трубопровода. При повреждении электропроводника происходит разрыв цепи, установленные на щите звуковые или световые сигналы сооЬщают о повреждении электропроводника и изол ции на конкретном участке трубопровода . Зна номер поврежденного участка, можно сразу определить его местоСОTo determine the location of the damage to the surface of the pipeline, connect the tester to the terminals to which the electrical conductors are connected. If there is no open circuit, the circuit is closed and the tester needle is deflected, if the circuit is broken, i.e. the electrical conductor and the insulation on the pipeline are damaged, the tester needle does not deflect, remains at zero. In addition, the open circuit can be determined by applying an electric current to each section of the pipeline. When an electrical conductor is damaged, the circuit is broken, sound or light signals installed on the shield indicate damage to the electrical conductor and the insulation in a particular section of the pipeline. Knowing the number of the damaged area, you can immediately determine its location.
