Method for protecting routes of ground-buried metal transmission pipelines, preferably gas pipelines, against the effects of lightning strokes, and the route lightning arrester for the application of this method
Method for protecting routes of ground-buried metal transmission pipelines, preferably gas pipelines, against the effects of lightning strokes, and the route lightning arrester for the application of this method
way of safeguarding routes arranged in earth metal pipelines, especially gas, from the effects of strikes of lightning is suchthe inside of oznacznikowych (3) of the pipeline (2) and (4) in addition profilowych daszków placed high voltage wires (6) of diameter o1 = 1,2 to 20 mm of the insulating (7) rozpływ power bolt (11) to the environment, having a strength dielektryczną of from 1 kv to 100 kv.the lower ends of through holes (3 ') made in oznacznikowych poles (3) on their kotwicami profilowymi (5) moves outside these columns.and their exposed ends (10) bends parallel to vertical sections (8) of the pipe in the direction of the pipeline (2) and in a safer distance (l) of at least 1 m from him,what causes the outflow of this current to ground (1).in turn, the essence piorunochrona is,that is him move bolt having double bent rod metal having function of high voltage (6) and the surrounding containment shield (7) of dielectric strength athey from 1 kv and 100 kv.with this instrument, along with his arch cover is formed with a vertical section (8) of a high voltage (6) placed inside of oznacznikowego (3) and combined withprofile photo visor (4) and in parallel to the shorter segment situated lower isolated segment (10) connected by laterally situated isolated segment (9) of the long vertical odcinkiem (8).
