Description

Technical Field

[0001] This utility model relates to a high-voltage component, specifically a high-voltage DC generator. Background Technology

[0002] AC and DC power equipment often need to undergo various insulation tests under DC high voltage, such as leakage current tests and withstand voltage tests. Impulse voltage generators also require high voltage DC as a power source. Therefore, DC generators are also one of the most basic test devices for high voltage impulse tests. The main feature of DC high voltage generators is that they can easily obtain higher DC voltages. In order to perform high voltage DC testing, high voltage DC generators can be used, or DC high voltage generators with higher voltage levels can be constructed.

[0003] In the prior art, 201020523301.X describes a high-altitude DC generator device. This utility model provides a high-altitude DC generator device, including a voltage multiplier cylinder and a capacitor voltage divider. The voltage multiplier cylinder is mounted on the base of the intermediate frequency transformer tank, and the capacitor voltage divider is mounted on the base of a capacitor. Both the voltage multiplier cylinder and the capacitor voltage divider have equalizing rings at their upper ends. A current-limiting resistor is connected between the equalizing rings on the voltage multiplier cylinder and the equalizing rings on the capacitor voltage divider. This device can perform on-site testing of DC parameters for 800kV system DC transmission electrical equipment and can also simultaneously accommodate DC withstand voltage testing of 500kV submarine cables.

[0004] Existing DC generators can adapt to high altitudes for further field testing, meeting the needs of high-altitude power testing. However, they also have limitations, such as the inability to adjust their position, the need for a fixed test location, and poor adaptability. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, this utility model provides a high-voltage DC generator.

[0006] This utility model is achieved using the following technical solution: a high-voltage DC generator, comprising a DC generator body, wherein the DC generator body is a DC current-conducting column, a DC generating component is provided on the DC current-conducting column, the DC generating component is a DC generating outer ring, a connecting component is provided between the DC generating outer ring and the DC current-conducting column, the connecting component is a connecting rod for connection, the connecting rod is distributed between the DC generating outer ring and the DC current-conducting column, a bottom liner is provided at the bottom of the DC current-conducting column, a positioning module is provided on the bottom liner, the positioning module is a positioning drive cylinder, a meshing end is provided on the bottom liner, and the positioning drive cylinder and the meshing end on the bottom liner are further locked by a locking pin.

[0007] The DC generating outer ring is divided into a top DC generating outer ring, a middle DC generating outer ring, and a bottom DC generating outer ring, and a generating gap is provided between the top DC generating outer ring, the middle DC generating outer ring, and the bottom DC generating outer ring.

[0008] The DC current-conducting column is provided with a current-conducting component, which is a thin current-conducting rod. The bottom liner is provided with a grounding component, which is a grounding rod.

[0012] Compared to existing technologies, this device employs a column-type main structure with a layered DC generator outer ring. The pre-reserved generation gaps between the DC generator outer rings of different heights optimize the electric field distribution and improve operational stability. Connecting rods are evenly distributed between the outer rings and the current-guiding columns, forming a stable support system. The positioning drive cylinder integrated into the bottom liner and the engagement end are doubly fixed by locking pins, significantly improving the accuracy of equipment installation and resistance to displacement. The current-guiding rods and grounding rods ensure a low-impedance conduction path, and the grounding rod configuration enhances the safety performance of the equipment. The bottom liner is equipped with moving rollers, which provide the equipment with flexible position adjustment capabilities. The drive cylinder then moves the bottom liner and the DC generator, making the position adjustment of the DC generator more convenient. The protective resistor at the top center is equipped with an external flange, which can further facilitate the integration and assembly needs with other equipment. Attached Figure Description
