Description

Technical Field

[0001] The utility model relates to the technical field of anti-corona tubes, in particular to an anti-corona tube for a transformer rectifier. Background Art

[0002] The anti-corona tube is also called the anti-corona ring or the anti-corona ring. The general anti-corona ring has two spiral structures with different diameters, and the spiral structures are sleeved on the cable. The prior art discloses a transformer rectifier anti-corona tube (CN202222104965.8), which belongs to the technical field of anti-corona tubes and is composed of a spiral body, a main locking ring, a secondary locking ring and a locking mechanism, wherein the main locking ring is fixedly connected to the lower end of the spiral body, one end of the main locking ring is provided with a hollow portion, and one end of the secondary locking ring close to the hollow portion is provided with an axial portion, the axial portion is rotatably connected in the hollow portion, and the locking mechanism is provided at the other end of the secondary locking ring, and the locking mechanism is connected to the main locking ring to fix the main locking ring and the secondary locking ring; under the obstruction of the screw rod, the arc block cannot be separated from the slot, thereby fixing the main locking ring and the secondary locking ring, keeping the spiral body more stable after being assembled on the cable, and will not move radially with the cable, providing a stable corona reduction function. In the actual installation process, the installation position is in the air, and more parts are inconvenient for construction, which limits the installation efficiency. During installation, the bolts and nuts need to be aligned and the bolts and nuts need to be turned and rotated to tighten them, and there is a certain amount of room for optimization.

[0003] The disclosure (announcement) number is CN219697498U, which discloses an anti-corona tube for a transformer rectifier, including a spiral body and a clamping ring for installing the spiral body, the clamping ring is disconnected from the middle, and the two parts of the clamping ring are hinged to each other to form a closed circular ring, and the cross sections of the two parts of the clamping ring are fixedly connected to the same ear plates, and the two ear plates are closed and limited by a locking member, and the corresponding connecting rods are pushed away from each other by the spring in the connecting rod, and the connecting rod pushes the corresponding connecting block to drive the corresponding clamping plate to move in the opposite direction, and the two clamping plates are away from each other, and the end faces of the clamping plates are clamped in the left half of the thrust groove to achieve locking of the two ear plates, and the two parts of the clamping ring remain in a closed state, replacing the two ear plates in the prior art by bolts to lock, without flipping and rotating the screws and nuts, and at the same time reducing the probability of losing the screw and nut accessories, the two ear plates have high locking efficiency and simple operation, which improves the overall installation efficiency and achieves quick installation.

[0004] Although the above scheme can make the two clamping rings for installing the spiral body detach from the screw nut for interlocking, the spiral body is only plugged into the top surface of the clamping ring at a single point, and the spiral body is very easy to detach from the clamping ring. The stability of the equipment in positioning the spiral body is general, and the cable clamping structure on the inner side of the clamping ring requires multi-point operation of the screw, and the operation of the equipment on the cable positioning structure is cumbersome and laborious. For this reason, we propose a transformer rectifier anti-corona tube. Utility Model Content
