Description

Technical Field

[0001] This invention relates to the field of cross-linked polyethylene insulated cable technology, specifically to cross-linked polyethylene insulated control cables. Background Technology

[0002] Cross-linked polyethylene (XLPE) insulated control cables are made by physically transforming the linear molecular structure of polyethylene into a three-dimensional network structure, which significantly improves the cable's high-temperature resistance. The long-term allowable operating temperature of the cable conductor can reach 90℃, and it can withstand high temperatures of 250℃. This is stronger than the high-temperature resistance of ordinary polyvinyl chloride (PVC) insulated cables (usually 70℃), reducing the risk of insulation aging or failure due to overheating.

[0003] Patent CN219105785U discloses a cross-linked polyethylene insulated control cable, including a cross-linked polyethylene insulating jacket, connecting blocks fixed at both ends of the cross-linked polyethylene insulating jacket, a buffer jacket fixed on the inner wall of the cross-linked polyethylene insulating jacket, and an installation block fixed on the inner wall of the buffer jacket. The installation block has an installation cavity, and the installation cavity has an installation device to prevent the wire from detaching. This patent ensures that the wire has strong resistance to tensile or shear forces by wrapping multiple insulating protective sleeves and wires around the outer surface of the insulating sleeve, and then providing support force through support columns, thereby enhancing the overall bending strength of the cable. The insulating sleeve and the installation block are connected by locking blocks and fixed connecting blocks to ensure that the wire and support columns cannot be easily pulled out of the installation cavity, thus preventing the wire from being pulled out of the protective jacket.

[0004] However, current cross-linked polyethylene (XLPE) insulated control cables have the following problems: during use, the joints of XLPE insulated control cables are prone to moisture damage, requiring maintenance personnel to perform tedious inspections and maintenance, which leads to poor maintenance results.

The square shell 8 is used to support the calcium chloride block 11 below. The calcium chloride block 11 is used to dry the moisture inside the insulating shell 1. When using this cable, the maintenance personnel open the insulation shell 1 and insert the protective sleeve 3 into the sealing ring 2. The sealing ring 2 moves the tear-resistant filler 4 towards the center, which in turn moves the cross-linked polyethylene insulation layer 5 towards the center. The cross-linked polyethylene insulation layer 5 then moves the copper core 6 towards the center. The maintenance personnel then fix the copper core 6 end-to-end and wrap it with insulating tape 7. The shells 1 and 2 are then closed and secured with bolts, completing the connection of the two control cable sections. The maintenance personnel then unscrew the bolts on the top cover 10 and pull the top cover 10 upwards using the handle 1001. The top cover 10 moves the calcium chloride block 11 upwards. The maintenance personnel then replace the top cover. The maintenance personnel then insert the top cover 10 into the slot of the insulating shell 1. The top cover 10 moves downward in the slot of the insulating shell 1, which in turn moves the calcium chloride block 11 downward. The calcium chloride block 11 enters the square shell 8. The moisture in the insulating shell 1 passes through the filter screen 9 and enters the square shell 8. The calcium chloride block 11 absorbs the moisture in the moisture and dries the control cable in the insulating shell 1. This allows the maintenance personnel to easily replace the calcium chloride block 11 in the top cover 10, thus avoiding the problem of poor maintenance effect of cross-linked polyethylene insulated control cables due to the inconvenience of replacing the calcium chloride block 11 during the maintenance process. An anti-loosening device 12 is provided at the top of the inside of the top cover 10. The anti-loosening device 12 is used to hold the end face of the tear-resistant filler 4. An anti-deformation device 13 is provided on the side of the anti-loosening device 12 that is far away from each other. The anti-deformation device 13 is used to support the tear-resistant filler 4.

[0021] Working principle: Open the insulating shell 1, insert the protective sleeve 3 into the sealing ring 2 respectively. The sealing ring 2 drives the tear-resistant filler 4 to move towards the center. The tear-resistant filler 4 drives the cross-linked polyethylene insulation layer 5 to move towards the center. The cross-linked polyethylene insulation layer 5 drives the copper core 6 to move towards the center. Fix the copper core 6 end to end and wrap it with insulating tape 7. Then close the shell 1 and shell 2 and fix it with bolts. Unscrew the bolts on the top cover 10 and pull the top cover 10 upward with the handle 1001. The top cover 10 drives the calcium chloride block 11 upward. Replace the calcium chloride block 11 on the top cover 10. Then insert the top cover 10 into the groove of the insulating shell 1. The top cover 10 moves downward in the groove of the insulating shell 1. The top cover 10 drives the calcium chloride block 11 downward. The calcium chloride block 11 enters the square shell 8.

During this downward movement, the vertical convex plate 121 contacts the convex arc rod 122. Under the pressure, the convex arc rod 122 slides to both sides within the square shell 8. The convex arc rod 122 then moves the ring plate 124 to both sides, pulling the spring 125. The spring 125 begins to store energy, facilitating the reset of the convex arc rod 122. The convex arc rod 122 then moves the perforated plate 123 to both sides, sliding on the surface of the cross-linked polyethylene insulation layer 5. The perforated plate 123 rests against the end faces of the tear-resistant filler 4, which pulls the cross-linked polyethylene insulation layer 5, preventing it from loosening and thus avoiding the problem of heat buildup on the surface of the cross-linked polyethylene insulation layer 5 during use.
