Voltage peak counter for current supply or communications channel - has absorbers with different response voltages with discharge tubes and nonlinear resistances and signal counters at light receivers

摘要

The counter system for voltage peaks has a number of voltage peak absorbers (c1,c2,c3) each with different response voltages (V1,V2,V3) for discharge pulses. They are interconnected (A,A') in parallel for the voltage peaks. Each voltage peak absorber (c1,c2,c3) has a split discharge tube (a1,a2,a3) and a non-linear resistance (b1,b2,b3) in series. Each discharge tube (a1,a2,a3) has a light receiver (d1,d2,d3) to detect emerging light. A counter (e1,e2,e3) for each light receiver (d1,d2,d3) detects and counts the light signals from them. The discharge tubes are an air gap, gas filled type or a gas sealed discharge tube of microgap type. The non-linear resistances are zinc oxide varistors. The photo-cell is of polycrystal as the main components of CdS, CdSe or PbS. The response voltages to absorb voltage peaks are structured so that V1 is less than V2 is less than V3 ... less than Vn. The non-linear resistances can also be silicon carbide varistors. USE/ADVANTAGE - The system is to register the voltage peaks and voltage fluctuations in current supplies and communication channels, and their incidence. The current surges are classified and sorted by their magnitudes, in a simple circuit, without highly sensitive photosensors, to count induced and penetrating voltage surges.
