Abstract
Sposób zabezpieczania tras ułożonych w ziemi metalowych rurociągów przesyłowych, zwłaszcza gazowych, przed skutkami uderzeń pioruna charakteryzuje się tym, że wewnątrz słupków oznacznikowych (3) rurociągu (2) oraz ich profilowych daszków (4) dodatkowo umieszcza się przewody wysokonapięciowe (6) o średnicy O1 = 1,2 do 20 mm z osłoną izolującą (7) rozpływ prądu pioruna (11) do otoczenia, posiadającą wytrzymałość dielektryczną wynoszącą od 1 KV do 100 KV, których dolne końce poprzez otwory (3') wykonane w słupkach oznacznikowych (3) nad ich kotwicami profilowymi (5) wyprowadza się na zewnątrz tych słupków, a ich odsłonięte końce (10) zagina się równolegle do pionowych odcinków (8) tych przewodów w kierunku rurociągu (2) i w bezpieczniej odległości (L) wynoszącej co najmniej 1 m od niego, co powoduje odpływ tego prądu do ziemi (1). Z kolei istota piorunochrona polega na tym, że stanowi go zwód pioruna posiadający podwójnie wygięty pręt metalowy spełniający funkcję przewodu wysokonapięciowego (6) i otaczająca go osłona izolująca (7) o wytrzymałości dielektrycznej wynoszącej od 1 KV - 100 KV, przy czym wygięcie tego pręta wraz z jego osłoną utworzone jest z dłuższego odcinka pionowego (8) przewodu wysokonapięciowego (6) umieszczonego wewnątrz słupka oznacznikowego (3) i połączonego z nim profilowego daszka (4) oraz równolegle usytuowany do tego odcinka krótszy dolny odizolowany odcinek (10) połączony poprzez poprzecznie usytuowany izolowany odcinek (9) z tym dłuższym pionowym odcinkiem (8).The way of securing the routes of underground metal transmission pipelines, especially gas pipelines, from the effects of lightning strikes is characterized by the fact that inside the marking posts (3) of the pipeline (2) and their profile roofs (4), high-voltage wires (6) with O1 diameter are additionally placed = 1.2 to 20 mm with insulating cover (7) lightning current flow (11) to the environment, having a dielectric strength of 1 KV to 100 KV, whose lower ends through holes (3 ') made in marking posts (3) above their profile anchors (5) are led outside these posts, and their exposed ends (10) are bent parallel to the vertical sections (8) of these lines towards the pipeline (2) and at a safer distance (L) of at least 1 m from it , which causes the current to drain to earth (1). In turn, the essence of the lightning protection lies in the fact that it is a lightning rod with a double-bent metal rod that performs the function of a high-voltage wire (6) and an insulating sheath (7) surrounding it with a dielectric strength of 1 KV - 100 KV, with the rod bending with its cover, it is formed of a long vertical section (8) of a high-voltage wire (6) placed inside the marker post (3) and a profile roof (4) connected to it, and a shorter, lower section isolated (10) parallel to this section, connected via a transversely located insulated section (9) with the longer vertical section (8).
