Screw drive electrode adjustable water resistor

Abstract

The invention discloses a screw drive electrode adjustable water resistor which comprises a resistor body. The inner side wall of the resistor body is provided with a group of sliding grooves, a movable electrode plate is installed in the sliding grooves, and an adjusting screw is installed on an output electrode sealing plate and is in matched connection with the movable electrode plate through threads. When rotating, the adjusting screw drives the movable electrode plate to move in the axial direction of the resistor body in the sliding grooves, and the movable electrode plate penetrates the output electrode sealing plate through spiral guiding. According to the screw drive electrode adjustable water resistor, the correction can be performed by adjusting the distance between electrodes of the water resistor, so that a good resistance state is maintained; compared with the prior art, the motion of repeatedly replacing an electrolyte solution is avoided, and the use cost is also reduced.

Description

technical field

[0001] The invention relates to the technical field of water resistance devices, in particular to a screw driven electrode adjustable water resistance. Background technique

[0002] The high-power pulse generating device is used to generate high-voltage pulses with large currents, and its load resistance or waveform modulation resistance usually uses a water resistance with a large power capacity. The working medium of the water resistor is usually an aqueous solution of copper sulfate or potassium chloride with a certain concentration. The disadvantage of traditional water resistance is that its resistance value is easy to change: on the one hand, the rise or fall of the ambient temperature affects the ion concentration in the electrolyte solution, which in turn affects the resistance value of the water resistance; on the other hand, the water resistance passes through large current and high voltage for a long time The pulse also changes its resistance valu...
