Problems solved by technology

Since high-power pulse generators usually use a sealed box to contain working media such as insulating oil or insulating gas, the replacement of water resistors is a very cumbersome process that consumes a lot of time and manpower, which directly leads to various high-power Inefficient operation of pulsed devices

Embodiment

[0017] Such as figure 1 As shown, a pneumatically adjustable water resistor includes a resistor body 3, and the interior of the resistor body 3 is provided with a through hole axially penetrating the resistor body 3, and the through hole is composed of a small diameter through hole and a large diameter through hole connected in sequence. The aperture of the small-diameter through-hole is smaller than that of the large-diameter through-hole, and the electrode A2 that slides along the small-diameter through-hole and closely matches the inner wall of the small-diameter through-hole is installed in the small-diameter through-hole, and the electrode A2 is installed in the large-diameter through-hole. The electrode B4 slides along the large-diameter through hole and closely fits the inner wall of the large-diameter through hole. The electrode A2 and the electrode B4 are two cylinders with different diameters. The through hole between the electrode A2 and the electrode B4 is filled wi...

Abstract

The invention discloses a pneumatic adjustable water resistor. The pneumatic adjustable water resistor comprises a resistor body (3), wherein a through hole which axially penetrates through the resistor body (3) is formed in the resistor body (3); the through hole consists of a small-diameter through hole and a large-diameter through hole which are communicated in sequence; the aperture of the small-diameter through hole is smaller than that of the large-diameter through hole; an electrode A (2) which slides along the small-diameter through hole and is in close fit with the inner wall of the small-diameter through hole is mounted in the small-diameter through hole; an electrode B (4) which slides along the large-diameter through hole and is in close fit with the inner wall of the large-diameter through hole is mounted in the large-diameter through hole; the through hole between the electrode A (2) and the electrode B (4) is filled with an electrolyte solution. The pneumatic adjustable water resistor has the benefits that the quick adjustment of the resistance value of the water resistor is realized; the detachment and the reconfiguration of the water resistor in a high-voltage situation are avoided; the operation is simple; the efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of water resistance devices, in particular to a pneumatically 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 value. In or...
