High-Sealed Coaxial Cable Connector with Secondary Voltage Divide

Abstract

The invention belongs to the technical field of pulse power, and particularly relates to a highly sealed coaxial cable connector having the secondary voltage dividing function. The highly sealed coaxial cable connector comprises a leading-out outer conductor, a threaded outer conductor, a gold-plated outer conductor, a leading-out inner conductor, a high-resistance resistor, a gold-plated inner conductor, an upper Teflon liner, a glass water pouring body and a lower Teflon liner. The highly sealed coaxial cable connector having the secondary voltage dividing function has the signal attenuation function by itself, so that no voltage dividing box is required. Therefore, the self-measuring system of the highly sealed coaxial cable connector is compact. The gas leakage rate of the highly sealed coaxial cable connector is improved to be 10<7>Pa*m3 / s. compared with the conventional gas leakage rate of 10<5>Pa*m3 / s, the gas leakage rate is improved by nearly two orders of magnitude. As a result, the highly sealed coaxial cable connector having the secondary voltage dividing function can be arranged on the outer wall of high-voltage equipment only by means of threads, and is convenient in installation.

Description

technical field [0001] The invention belongs to the technical field of pulse power, and in particular relates to a highly sealed coaxial cable connector with two-stage partial pressure. Background technique [0002] In the field of pulse power technology, devices used to measure high-voltage short-pulse signals include capacitive voltage divider foils, Rogowski coils, and the like. Taking the device used for measuring high voltage-capacitive voltage divider foil as an example, firstly, the voltage signal is measured by the voltage divider foil (11) adhered to the inner surface of the high-voltage equipment; secondly, the coaxial cable installed on the outer wall of the high-voltage equipment is used to connect the voltage signal. Thirdly, the signal amplitude is attenuated through the voltage divider box (16) installed on the coaxial cable connector; finally, the useful signal is introduced into the oscilloscope (18) through the cable (17), such as figure 1 shown.

AI Technical Summary

Problems solved by technology

Obviously, figure 1 The existence of the middle voltage divider box (16) affects the compactness of the measurement system; at the same time, the coaxial cable connector also has the possibility that the gas leakage rate cannot meet the requirements

This is because there is a possibility of gas leakage between the gold-plated inner conductor (3) of the coaxial cable connector and the lower PTFE bushing (14); at the same time, the single-channel axial seal between the cable connector and the high-voltage equipment There is also the possibility of gas leakage
