Abstract

Sposób lokalizacji uszkodzeń kabla elektroenergetycznego, zwłaszcza w przestrzeniach zagrożonych wybuchem, polega na badaniu rezystancji upływności, w którym badany kabel (K) odłącza się od zasilania i odbioru z udostępnieniem żył wewnętrznych (Z) i ekranu (E) z jednej strony kabla, z pozostawieniem uziemionego ekranu z drugiej strony kabla, po czym do poszczególnych żył kabla podłącza się zespół zasilacza prądu pomiarowego (Zas) i nadajnika (N), następnie działa się mechanicznie w określonych miejscach na badany kabel, powodując w nim zmianę naprężenia mechanicznego, wywołującego zmianę rezystancji upływności (Ru). Informacja o zmianie przekazywana jest sygnałem o częstotliwości radiowej z nadajnika poprzez ekran kabla, będący anteną nadawczą, do przenośnego odbiornika informującego operatora o zmianie rezystancji upływności.The method of locating power cable damage, especially in potentially explosive atmospheres, consists in testing the leakage resistance in which the tested cable (K) is disconnected from the power supply and receiving with access to internal veins (Z) and shield (E) on one side of the cable, leaving grounded shield on the other side of the cable, after which the power supply of the measuring current (Zas) and the transmitter (N) are connected to the individual wires of the cable, then it works mechanically in specific places on the tested cable, causing a change in the mechanical stress causing a change in leakage resistance (Ru). Information about the change is transmitted by a radio frequency signal from the transmitter through the screen of the cable, which is the transmitting antenna, to the portable receiver informing the operator about the change in leakage resistance.
