Schiaramento/annotazione:Gate. For protection against atmospheric overvoltage of insulation of electric
equipment of alternate current by the frequency 50-60 Hz
Descrizione del marchio dettagliata:For networks with any system of neutral grounding (15, 2
0, 35 kW) are being manufactured and for networks with effectively earthed neutral (33, 66, 110,
132, 150, 220 kW).
consist of one or several standard cells, each of êîòî
paradise includes the bloc of multiple spark gap and working ðåçèñòî
RU. The multiple spark gap is in series with ðàáî÷è
mi by resistors, is closed hermetic àðìèðîâàííì case and has been squeezed compressor
. The spark gap column is closed by the lid, protecting the top end the element
and from atmospheric precipitations. The phase lead of high-voltage line ïîäêëþ
÷àåòñÿ to contact plate in the lid, and the grounding lead _ to bibliographic description
ëòó of steel base plate directly or through registrant ñðà of áàòûâàíèÿ. To lid of upper element of spark gaps on nominal íàïðÿ
æåíèå 110 kW and higher is fastened shading ring.
