Abstract

The invention provides a novel resistance-capacitance parallel voltage divider, which comprises a high voltage arm and a low voltage arm, and is characterized in that stray inductance is greatly reduced by adopting measures such that a plurality of capacitance branches are connected in parallel, parallel damping resistors with low resistance are connected in series at the head end of the high voltage arm and each capacitance branch, and both a head-end damping resistor of the high voltage arm and a low-sensitive resistance-capacitance slice of the low voltage arm adopt a low-sensitive resistance-capacitance component, good damping is performed on high-frequency oscillation and overshoot, the voltage waveform is optimized and adjusted, nanosecond pulses, lightning waves, operating impact and power frequency AC and DC high-voltage signals can be simultaneously measured.

Description

technical field [0001] The invention belongs to the field of pulse power technology and electric power industry, and particularly relates to a novel resistance-capacitance parallel voltage divider. Background technique [0002] The voltage divider is a key device for pulse power technology and high voltage measurement in the power industry, and it plays an increasingly important role in the measurement of nanosecond pulses, lightning shocks, operating shocks, and power frequency AC and DC voltages. Long-lasting research has been carried out on voltage dividers at home and abroad. Common forms include resistor voltage dividers, capacitor voltage dividers, resistor-capacitor series voltage dividers, and resistor-capacitor parallel voltage dividers. At present, all kinds of voltage dividers have inherent defects that are difficult to overcome. [0003] The resistor divider is suitable for measuring low frequency and DC signals, but its response speed is slow, and it is difficu...
