On-line measurable adjustable water resistor suitable for Blumlein pulse forming line, and method

Abstract

The invention discloses an on-line measurable adjustable water resistor suitable for a Blumlein pulse forming line, and a method. The high voltage output terminal of a Blumlein line is in connection with an adjustable water resistor; meanwhile, the outer cylinder of the Blumlein line is provided with an earthing device corresponding to the high voltage output terminal of the Blumlein line. In normal use, the adjustable water resistor and a Blumlein pulse forming line are used as a whole; for measuring a resistance value, the medium oil in a fuel tank does not need to be discharged; medium oil does not need to be discharged in a water resistance vale test and adjusting process, thereby reducing workload. The fixed electrode of the water resistor is grounding, thereby completely eliminating various circuit element influence to water resistance value test, wherein the various circuit elements are in connection with the water resistor through a high voltage output terminal and an output cable, and guaranteeing measurement precision and accuracy.

Description

technical field [0001] The invention relates to an adjustable water resistance and a measuring kit thereof, which can be installed in an output oil tank of a Blumlein pulse forming line, in particular to an online measurable and adjustable water resistance and a method suitable for the Blumlein pulse forming line. Background technique [0002] The Blumlein pulse forming line is a pulse forming device often used in the field of high-voltage pulses. Its main body is a three-layer coaxial structure, the outer cylinder is grounded, the inner cylinder is connected to the output end, and the middle cylinder is connected to the charging end. The main switch of the Blumlein line at the connection between the charging end and the middle barrel is turned on, and the middle barrel and the outer barrel are short-circuited at this port, and a short pulse similar to a square wave can be generated at the high-voltage output end connected to the inner barrel. The main body of the Blumlein l...

Problems solved by technology

[0005] The purpose of the present invention is to provide an online measurable and adjustable water resistance and method suitable for Blumlein pulse forming lines, so as to solve the problems that the resistance value of the current Blumlein line adjustment resistance changes quickly, each measurement workload is large, and the accuracy is low.

The present invention is an improvement to the existing Blumlein pulse forming line, aiming at the resistance value of the current Blumlein pulse forming line changing with time and temperature, each measurement and adjustment of the resistance needs to empty the medium oil in the oil tank. Due to the problems of large workload and low efficiency, the applicant makes appropriate improvements on the existing Blumlein pulse forming line. The improvement is that an adjustable water resistance is connected to the high-voltage output end of the Blumlein line. At the same time, A grounding device corresponding to the high-voltage output end of the Blumlein line is installed on the outer cylinder of the Blumlein line. In normal use, the adjustable water resistance and the Blumlein pulse forming line are used as a whole. When the medium oil is discharged out, you only need to use the grounding device to contact the high-voltage output end of the Blumlein line, short the fixed electrode of the water resistance to the ground potential through the high-voltage output end, and then disconnect the movable electrode of the water resistance from the grounding plate, so that the water The active electrode of the resistor is at the floating potential, and then the resistance value of the water resistor can be directly measured with a multimeter, so that the medium oil can be eliminated, thereby reducing the workload
