Description

Technical Field

[0001] The utility model relates to an arc extinguishing structure, in particular to a compact and efficient arc extinguishing structure, belonging to the technical field of high-voltage arc extinguishing. Background Art

[0002] The high-voltage arc extinguishing structure is an important part of the power system for quickly cutting off the current and extinguishing the arc, and its design aims to ensure the safe and stable operation of the circuit and equipment. The basic principle of the arc extinguishing structure is based on the characteristics and behavior of the arc. The arc is a discharge phenomenon generated when the current is interrupted in an electrical device or system, with characteristics such as high temperature, high energy, and strong electromagnetic radiation, and is prone to causing dangers such as fires, explosions, and equipment damage. Therefore, extinguishing the arc has become an important task for protecting power equipment and systems.

[0003] When the existing structures with arc extinguishing performance are in use, multiple arc extinguishing chambers are often arranged in a one-by-one arrangement, resulting in an overly large overall volume of the arc extinguishing structure, which is not convenient for installation and use. Moreover, a single series arc extinguishing circuit is difficult to cope with large current scenarios, and the energy in the arc extinguishing chamber cannot be released in time, easily causing equipment damage. For this reason, a compact and efficient arc extinguishing structure is proposed. Summary of the Utility Model

[0004] In view of this, the utility model provides a compact and efficient arc extinguishing structure to solve or alleviate the technical problems existing in the prior art, and at least provide a beneficial option.

The arc extinguishing assembly includes a first support sleeve, a first installation groove, a first spherical electrode, a second support sleeve, a second installation groove, a second spherical electrode, a first arc extinguishing chamber, a second arc extinguishing chamber, and a third arc extinguishing chamber;

[0006] The inner side wall of the first support sleeve is evenly provided with first installation grooves, the inner side wall of the first installation grooves is provided with first spherical electrodes, the second support sleeve is fixedly connected inside the first support sleeve, the inner side wall of the second support sleeve is evenly provided with second installation grooves, the inner side wall of the second installation grooves is provided with second spherical electrodes, the outer side wall of the second spherical electrodes is provided with a first arc extinguishing chamber, the inner side wall of the first support sleeve is evenly provided with a second arc extinguishing chamber, and the inside of the second support sleeve is evenly provided with a third arc extinguishing chamber. The current plate introduces the arc, and the arc enters different second spherical electrodes through the high-voltage electrodes respectively, and sequentially passes through multiple chambers of the first arc extinguishing chamber, the second arc extinguishing chamber, and the third arc extinguishing chamber, gradually realizing arc extinguishing. Since the arc extinguishing path adopts a curve design, compared with the traditional straight-line design, the internal space of the arc extinguishing structure is fully utilized under the same arc extinguishing gap, making the arc extinguishing structure more compact.

[0007] Further preferably: The first arc extinguishing chamber is installed between an adjacent first spherical electrode and a second spherical electrode.

[0008] Further preferably: The second arc extinguishing chamber is installed between adjacent first spherical electrodes.

[0011] The outer side wall of the first support sleeve is fixedly connected to the insulating housing, and a high-voltage electrode is installed on the top of the first support sleeve.

[0012] Further preferably: A drainage plate is fixedly connected to the top of the high-voltage electrode.

[0013] Further preferably: The outer side wall of the first support sleeve is fixedly connected to an insulating umbrella skirt.

The diversion plate 13 introduces an electric arc, and the electric arc enters different second spherical electrodes 26 through the high-voltage electrode 12 respectively, and successively passes through multiple chambers of the first arc extinguishing chamber 27, the second arc extinguishing chamber 28 and the third arc extinguishing chamber 29, gradually realizing arc extinguishing. Since the arc extinguishing path adopts a curve design, compared with the traditional straight-line design, under the condition of the same arc extinguishing gap, the internal space of the arc extinguishing structure is fully utilized, making the arc extinguishing structure more compact.

[0029] In this embodiment, specifically: the first arc extinguishing chamber 27 is installed between adjacent first spherical electrodes 23 and second spherical electrodes 26, and arc extinguishing is carried out between the adjacent first spherical electrodes 23 and second spherical electrodes 26 through the first arc extinguishing chamber 27.
