Analysis of XLPE cable parameters subject to thermo aging

Abstract

Modern marine vessels use electrically driven rudders; cruise liners, gas carriers, tankers are equipped with Azipod systems manufactured by the Swedish-Swiss company ABB. Gondola-type propellers make it possible to break ice when the vessel is moving astern, therefore such vessels are used for work on the Northern Sea Route, in particular, when working on the Yamal LNG project. The 22MW Azipod propulsion system rotates 360° and enables difficult maneuvering without the assistance of tugs. When operating such propellers, powerful diesel generators are installed on the ship. For the transmission of electricity, ship cables are used, which are subject to increased requirements that meet the standard of the International Electrotechnical Commission. Modern marine vessels are equipped with XLPE or EPDM insulated cable lines; industrial production of these cables is carried out in the Russian Federation. In the course of the study, a method for auditing the state of insulation has been considered based on an assessment of the change in the tangent of the angle of dielectric losses in the process of thermal aging of the cable of the PvBPng(A)-HF brand. Measurements of the tangent of the dielectric losses' angle have been carried out with a Tangens-2000 insulation parameter meter. Современные морские суда используют винторулевые колонки с электроприводом; круизные лайнеры, газовозы, танкеры оборудуются системами Azipod производства шведско-швейцарской компании ABB. Винторулевые колонки гондольного типа позволяют при движении судна кормой разбивать льды, поэтому такие суда используются для работы на Северном морском пути, в частности при работе по проекту "Ямал СПГ". Движитель Azipod мощностью 22 МВт осуществляет вращение на 360º и обеспечивает выполнение сложного маневрирования судном без помощи буксиров. При эксплуатации подобных движителей на судне устанавливаются мощные дизель-генераторы. Для передачи электроэнергии используются судовые кабели, к которым предъявляются повышенные требования, соответствующие стандарту Международной электротехнической комиссии. Современные морские суда оборудуются кабельными линиями с изоляцией из сшитого полиэтилена или этиленпропиленовой резины; в Российской Федерации осуществляется промышленное производство этих кабелей. В процессе исследования рассмотрен метод аудита состояния изоляции на основе оценки изменения тангенса угла диэлектрических потерь в процессе теплового старения кабеля марки ПвБПнг(А)-HF. Измерения тангенса угла диэлектрических потерь выполнялись измерителем параметров изоляции Тангенс-2000. Published Refereed
