T-bridge overvoltage diverter network esp. for leakage monitor system in pipeline networks

摘要

The T-bridge diverter is provided with overvoltage suppressors esp. for e.g. leakage monitoring systems in pipeline networks. The high energy overvoltage suppressors (10-13) and the units with avalanche discharge stretches (20-22) are provided, which respectively are connected parallel to the overvoltage suppressors and so dimensioned, that they respond to an overvoltage, at least restricting this up to the overvoltage suppressors. Diodes (20, 21, 22) are integrated in the avalanche discharge stretches, and are connected in the blocking direction. Protective resistances (30, 31, 32) are connected in series to the diodes, which act to limit the current flowing through the diodes.
