Abstract
Description
Technical Field
[0001] This utility model relates to the field of high-voltage electrical conductor connection, and in particular to a detachable conductor device for combined electrical appliances. Background Technology
[0002] For conventional detachable conductor structures used in GIS (Gas Insulation System), to meet insulation break requirements, the internally connected detachable conductors typically need to be removed from the housing. To facilitate conductor removal, the housing of the chamber containing the detachable conductor needs to be relatively large. After removal, a shielding ring must be installed on the exposed conductor within the chamber to meet insulation requirements. Therefore, using existing conductor structures involves a significant workload and is not conducive to long-term preservation of the conductors after disassembly. Utility Model Content
[0003] The purpose of this invention is to address the problems existing in the background technology by proposing a detachable conductor device for combined electrical appliances. After the movable conductor is detached, it does not need to be removed and can be left directly in the gas chamber, which facilitates disassembly and allows for long-term preservation.
[0004] The present invention provides a detachable conductor device for combined electrical appliances, comprising a conductive base, a movable conductor, and a spring contact base; the inner side of the spring contact base is hollow, and a fixing block is detachably connected to the inner side of the spring contact base; the movable conductor is inserted into the spring contact base, and one of the movable conductors is detachably connected to either the conductive base or the fixing block; when the movable conductor is connected to the conductive base, it is in a conductor-connected state; when the movable conductor is connected to the fixing block, it is in a conductor-disconnected state, and an insulation break is formed between the movable conductor and the conductive base.
[0005] Preferably, the conductive base has a through hole, the movable conductor has a threaded hole, and a bolt that is threadedly connected to the threaded hole passes through one of the through holes.
[0006] Preferably, the lower part of the movable conductor is hollow and has an internal thread, and the fixed block has an external thread that matches the internal thread.
[0007] Preferably, the fixing block has a second through hole, the spring contact seat has a second threaded hole, and a connecting bolt that is threadedly connected to the second threaded hole is inserted through the second through hole.
[0008] Preferably, the conductive base, the movable conductor, and the spring contact are distributed from top to bottom.
[0009] Compared with the prior art, this utility model has the following beneficial technical effects: The movable conductor in this utility model, after disassembly, does not need to be removed from the air chamber; it remains directly inside, facilitating disassembly and allowing for long-term preservation. By removing the bolts, the connection between the conductive base and the movable conductor is severed. The movable conductor is then pressed down and rotated, connecting it to the fixed block via a threaded connection. At this point, the movable conductor detaches from the conductive base, forming an insulation break between them. Since the movable conductor is not removed from the air chamber of the housing, its preservation is excellent. Attached Figure Description

[0013] like Figure 1 and Figure 2 As shown in the figure, this embodiment proposes a detachable conductor device for combined electrical appliances, including a conductive base 1, a movable conductor 3, and a spring contact 4, which are arranged sequentially from top to bottom. The conductive base 1 and the spring contact 4 are both installed inside the housing by bolt connection, and the movable conductor 3 is always located in the housing air chamber.
[0014] The conductive base 1 has a through hole, and the movable conductor 3 has a threaded hole. A bolt 2, which is threaded into the through hole, is inserted into the threaded hole. The conductive base 1 has an opening on its side to facilitate the installation and removal of the bolt 2.
[0015] The inner side of the spring contact 4 is hollow, and a fixing block 5 is detachably connected to the inner side of the spring contact 4. The fixing block 5 has two through holes, and the spring contact 4 has two threaded holes. A connecting bolt that is threaded into the threaded hole passes through the two through holes. The fixing block 5 is installed on the spring contact 4 using the connecting bolt, which is convenient for installation.
[0016] The movable conductor 3 is hollow at the bottom and has internal threads, and the fixed block 5 has external threads that are compatible with the internal threads.
[0017] The movable conductor 3 is inserted into the spring contact seat 4, and one of the movable conductors 3 can be detachably connected to the conductive seat 1 or the fixed block 5. For example... Figure 1 As shown, when the movable conductor 3 is connected to the conductive base 1, it is in a conductive connected state. Figure 2As shown, when the movable conductor 3 is connected to the fixed block 5, it is in a conductor disconnected state, and an insulation break is formed between the movable conductor 3 and the conductive seat 1.
[0018] In this embodiment, the movable conductor 3, after disassembly, does not need to be removed from the air chamber; it remains inside, facilitating disassembly and allowing for long-term preservation. To disassemble the movable conductor 3, first remove bolt 2 to disconnect the connection between the conductive base 1 and the movable conductor 3. Then, press down on the movable conductor 3, causing it to move inwards towards the spring contact 4. When the movable conductor 3 contacts the fixed block 5, rotate it to connect it to the fixed block 5 via a threaded connection. At this point, the movable conductor 3 detaches from the conductive base 1, creating an insulation break between them. Since the movable conductor 3 is not removed from the housing's air chamber, preservation is excellent. The housing size can be designed to be relatively small, still meeting the installation requirements of various components.
[0019] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
