Description

Technical Field

[0001] This utility model relates to the field of cable de-icing technology, specifically to a DC de-icing power supply multi-machine parallel de-icing device. Background Technology

[0002] High-voltage transmission lines are a core component of power transmission and play a vital role in the power system. In southern my country, low winter temperatures, abundant rainfall, and high humidity make them prone to icing. If ice buildup on lines is not removed promptly, exceeding the permissible ice thickness can cause incalculable damage to the power system.

[0003] DC current de-icing technology is one of the most widely used de-icing technologies. However, existing devices are limited by the current limit of power devices (such as thyristors), and the maximum output current of a single unit is usually less than 5kA. For main lines or large cross-section conductors in heavily iced areas, the rated current of a single unit is insufficient, resulting in low de-icing efficiency or even failure. The above problems can be solved by connecting multiple units in parallel. However, connecting multiple units in parallel requires workers to tighten multiple wiring bolts, which makes the wiring work more cumbersome and reduces the de-icing efficiency. In order to solve the above problems, this utility model provides a DC de-icing power supply multi-unit parallel de-icing device. Utility Model Content

[0004] To address the aforementioned technical shortcomings, the purpose of this utility model is to provide a multi-unit parallel de-icing device for DC de-icing power supplies. By using springs to press against the wire clamping plate to fix the cables, workers can quickly connect the wires, thereby improving the efficiency of de-icing.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention provides a DC de-icing power supply multi-machine parallel de-icing device, comprising:

[0009] Preferably, the size of the opening at the bend of the quick-connect section is smaller than the diameter of the bend.

[0010] Preferably, the end of the quick-connect section with the bend opening furthest from the straight section is folded outward to form an outwardly flared opening.

[0011] Preferably, each end of the terminal block is equipped with a storage box for storing the first common cable and the second common cable.

[0012] Preferably, the storage box includes:

[0015] A storage shaft is rotatably mounted between the box body and the box cover.

[0016] Preferably, a conductive shaft is fixedly connected to the bottom side wall of the housing, the lower end of the storage shaft is rotatably connected to the conductive shaft, the conductive shaft is electrically connected to the wiring part on the terminal block, and the first common cable and the second common cable are respectively electrically connected to the corresponding conductive shaft through brushes.

[0017] Preferably, the upper end face of the storage shaft is provided with a groove, and a prism adapted to the groove is rotatably mounted on the box cover. The prism is fixedly connected to a rotating plate rotatably mounted on the box cover.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] This utility model provides a DC de-icing power supply multi-machine parallel de-icing device, such as... Figures 1 to 6 As shown.

[0036] Example 1:

[0037] A multi-unit parallel de-icing device using DC de-icing power supplies includes a first common cable 1, a second common cable 2, and terminals 4. Both the first common cable 1 and the second common cable 2 are equipped with quick-connect parts 3, which can be quickly connected to the icing cable. The terminals 4 have multiple connection points that are electrically connected to an external DC power supply. These connection points are connected in parallel to the first common cable 1 and the second common cable 2, respectively. By connecting multiple DC power supplies to these connection points, multiple DC power supplies can be connected in parallel and de-iced via the first common cable 1 and the second common cable 2.

[0038] The quick-connect section 3 includes a straight section and a bent section. The bent section is arc-shaped and has an opening on the side facing the straight section. The diameter of the arc of the bent section is smaller than the diameter of the cable, and the size of the opening is smaller than the diameter of the bent section. The quick-connect section 3 is made of an elastic conductor (e.g., copper sheet). It is clamped on the icing cable by the elastic deformation of the bent section, so that the first common cable 1 and the second common cable 2 can be quickly electrically connected to the icing cable.

[0039] Example 2:

[0040] Based on Embodiment 1, in order to facilitate carrying and protect the first common cable 1 and the second common cable 2, storage boxes are fixedly installed at both ends of the terminal 4, and the two storage boxes are used to store the first common cable 1 and the second common cable 2 respectively.

[0041] The storage box includes a box body 5, which is fixedly connected to the end face of the terminal block 4. The upper end of the box body 5 has an opening, and a box cover 6 is installed at the opening of the box body 5. A storage shaft 7 is rotatably installed inside the box body 5. The storage shaft 7 can wind and store the first common cable 1 or the second common cable 2. A conductive shaft 8 is fixedly connected to the inner side wall of the lower end of the box body 5. The conductive shaft 8 is electrically connected to the wiring part. The first common cable 1 and the second common cable 2 are respectively electrically connected to the corresponding conductive shaft 8 through brushes, so that a stable electrical connection can be achieved when the storage shaft 7 rotates to store the first common cable 1 and the second common cable 2.

[0042] A prism 10 is rotatably mounted on the inner side of the lid 6. A groove 9 adapted to the prism 10 is provided on the storage shaft 7. The prism 10 is connected to the rotating plate 11 rotatably mounted on the lid 6 via a connecting shaft. A slot 12 is provided on the upper side of the rotating plate 11. A handle 13 is rotatably mounted inside the slot 12. By rotating the handle 13, the angle of the handle 13 can be adjusted so that the handle 13 is perpendicular or parallel to the upper side of the rotating plate 11. This allows the rotating plate 11 to be rotated conveniently when in use and folded up for easy carrying when not in use.

[0043] The first common cable 1 or the second common cable 2 can be retrieved or deployed by rotating the storage shaft 7.

[0044] Example 3:

[0046] A pressure plate 17 is connected to the upper side wall of the wiring hole 15 via a spring 16. A conductive layer is provided on the inner side wall of the wiring hole 15. The spring 16 has a clamping force that presses the pressure plate 17 against each other. Under the action of the clamping force of the spring 16, the pressure plate 17 can cooperate with the inner side wall of the wiring hole 15 to clamp and fix the DC power supply cable, thereby completing the wiring of the DC power supply.

[0047] A sliding plate 18 is slidably installed inside the fixing plate 14. The sliding plate 18 is fixedly connected to the corresponding wire clamping plate 17. The upper end of the sliding plate 18 passes through the upper end of the fixing plate 14 and folds to one side, which makes it convenient for the staff to pull the sliding plate 18. The sliding plate 18 and the fixing plate 14 are both made of insulating material. When connecting or disconnecting wires, the staff can control the position of the wire clamping plate 17 by sliding the sliding plate 18, which makes it convenient to quickly connect the DC power supply to the wiring part or disconnect the DC power supply from the wiring part.
