Embodiment Construction
[0016] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0017] Such as figure 1 As shown, the high-frequency and high-voltage measurement device of the present invention includes: a voltage divider for introducing a high-voltage signal; a data acquisition unit for collecting the divided voltage signal of the voltage divider; and a device for processing and displaying the sampling signal of the data acquisition unit Data processing and display unit. In this embodiment, the voltage divider is a resistive voltage divider, but those skilled in the art may also use a known voltage divider such as a capacitive voltage divider or a resistance-capacitance voltage divider. The voltage divider is sealed by high-voltage insulating oil or other high-voltage insulating materials to solve the measurement deviation caused by high-voltage corona. Among them, the high-voltage input signal is connected between the resisto...

Description
【Technical field】 [0001] The invention relates to a high-frequency and high-voltage measuring device, which is a high-frequency and high-voltage measuring device for measuring high-frequency and high-voltage signals through signal acquisition and data processing. 【Background technique】 [0002] The current high voltage referred to in the industry generally refers to a voltage above 10kV. At present, the commonly used high-voltage measurement methods mainly use voltage dividers and transformers combined with ammeters, use voltage dividers to measure DC (constant current) high voltage or power frequency high voltage, and use transformers to measure the effective value of power frequency high voltage. Existing high-voltage measurement devices cannot measure the peak value of power frequency high voltage, the effective value and peak value of various waveforms of pulsating DC (such as power frequency half-wave, full-wave rectification, three-phase 6 peaks, three-phase 12 peaks, ...
