| 摘要 |
<p>The present invention relates to a circuit arrangement for stabilization of isolated direct-current network ground potential, wherein said network being represented by two pole terminals (1) and (2), a ground terminal (3) and a terminal (12) of the network electrical center. The invented circuit arrangement comprises a voltage indicator (4), a limiter (6), a meter (7) of unsymmetrical isolating currents, a control circuit (8) and an evaluation circuit (9), whereby said evaluation circuit (9) contact or contactless output, usable for network safety or for signaling, is connected to signal terminals (10) and (11). Said network electrical center terminal (12) is connected either to a natural center of isolated direct-current network or to s source (5) of the network artificial center.</p> |
