| Zusammenfassung: | Title from the title-page. Processes of the electrical ageing by the dielectrics are usually connected with the accumulation of space charge during electrical loading and with the structural breaking in substance at molecular and over molecular level. The subject of this article is a research into the influence of the space charge to the electrical ageing and the service life of two polymer dielectrics which are widely used in construction of electro physical installations as isolation and construction materials: low-density polyethylene (LDPE) and polymethylmethacrylate (PMMA). Practical interest is in a research of conducting polymer isolation under action of ionizing radiations because they make destructive influence to the polymer and change the terms for space charge accumulation in it as well. The analyzed materials were studied in a frequent influence regime of high voltage impulses of microseconds range by the following frequency till 1 kHz. The space charge accumulation was studied by the methods of acoustic and proton sounding. As a result it could be established that in the researched diapason of duration and following frequency of high voltage pulses there is the space charge accumulation in both researched polymers neither before nor after radiation. Consequently electrical ageing of these dielectrics in electrical loading used regime is conditioned by the structural breaking processes. Режим доступа: из корпоративной сети ТПУ Text files |
