TECHNICAL FIELD

[0001] The present application relates to the technical field of cable installation terminals, and more particularly to an extra-high voltage intelligent outdoor terminal. BACKGROUND

[0002] In the process of cable installation, the extra-high voltage intelligent outdoor terminal is a key interface for connecting outdoor extra-high voltage cables and power grid equipment. The transmission voltage of the extra-high voltage cable is extremely high, up to 800 kV or 1000 kV. The outdoor terminal realizes high-voltage insulation isolation between the cable conductor and the external environment through an insulating sleeve material, prevents arc discharge or short circuit, and ensures the safety of installation personnel and equipment.

[0003] In the existing public literature, patent No. CN221727921U discloses a multifunctional outdoor terminal.

[0024] Technical effects and advantages of the present application:

[0025] The present application uses a self-adjusting mounting assembly. Under the action of gravity of the lead sleeve strip, the lead sleeve strip drives the sliding sleeve and the infrared sensor to move downward along a circular arc path, while the circular ring column remains stationary, guiding the movement of the sliding sleeve. When the lead sleeve strip drives the sliding sleeve to the lowest end position of the included angle between the collecting sleeve and the limiting ring, the terminal sleeve can automatically and intelligently install the infrared sensor to the lowest end position of the included angle according to the installation angle of the wiring terminal and the core, and can automatically and intelligently adjust to the installation position of the oil leakage monitoring according to the installation angle of the wiring terminal and the core, thereby improving the efficiency of cable terminal installation.

[0026] The present application uses a self-linkage assembly. Two counterweights and supporting blocks are used to drive the sharp end and the groove ring to move downward along a circular arc path. The groove ring slides along the outer wall of the positioning column outside the terminal sleeve. The groove ring drives the flow guide pipe, the hole pipe and the sliding sleeve to move synchronously along a circular arc path. Finally, the top inlet of the flow guide pipe is located at the lowest end position of the included angle between the groove ring and the top cover. In this way, the terminal sleeve can automatically adjust the top inlet of the flow guide pipe to the lowest end position of the included angle of oil leakage monitoring according to the installation angle of the wiring terminal and the core, and adapt to different installation scenarios. The self-adjusting installation improves the efficiency of cable terminal installation.

[0027] When oil leaks between the sealing ring and the terminal sleeve, the insulating oil flows through the gap between the sealing ring, the core and the insulating sleeve under the action of gravity to the lowest end of the included angle between the collecting sleeve and the limiting ring. The infrared sensor senses the oil leakage. When oil leaks at the connection between the wiring terminal and the terminal sleeve, the insulating oil drips to the lowest end of the included angle between the groove ring and the top cover along the inclined surface at the top of the terminal sleeve, and then flows to the above-mentioned lowest end through the flow guide pipe and the hole pipe. Similarly, the infrared sensor senses the oil leakage. Only one infrared sensor can detect the real-time self-adjusting detection of oil leakage at two places. Not only is the self-adjusting installation more efficient, but also high-efficiency intelligent detection of two places is realized.

[0028] In summary, through the mutual influence of the above-mentioned multiple effects, first, the lead sleeve strip drives the sliding sleeve to the lowest end position of the included angle between the collecting sleeve and the limiting ring, while the flow guide pipe moves downward along a circular arc path, and the top inlet of the flow guide pipe is automatically adjusted to the lowest end position of the included angle of oil leakage monitoring. In summary, the terminal sleeve can automatically and intelligently install the infrared sensor and the top inlet of the flow guide pipe to the lowest end position of the included angle according to the installation angle of the wiring terminal and the core, and automatically adjust to the installation position of the oil leakage monitoring, thereby improving the efficiency of cable terminal installation.

In order to move the sliding sleeve 6 downward along the circular path under the action of the gravity of the lead sleeve 7, the sliding sleeve 6 moves downward along the circular path guided by the outer wall of the circular column 5, until the sliding sleeve 6 is rotated to the bottommost position by the lead sleeve 7, so that the infrared sensor 8 can be automatically and intelligently installed at the lowest angle position, and automatically adjusted and installed, and at the same time, the self-linkage assembly drives the flow guide pipe 10 to move downward along the circular path, realizing linkage installation operation.

[0041] In the embodiment, as shown in Figure 4 The gap is provided between the infrared sensor 8 and the limiting ring 4, and the sliding sleeve 6 is slidably connected with the limiting ring 4, so that the gap facilitates the self-adjusting movement of the infrared sensor 8, and at the same time, the gap fills the leaked insulating oil, so that the infrared sensor 8 can feel whether there is a leakage problem.

[0042] In the embodiment, as shown in Figure 6 Figure 8 ​​As shown, the self-linking assembly includes: a grooved ring 11, fixedly connected to the top of the guide pipe 10, rotatably connected to the terminal sleeve 1, and a positioning post 12 slidably connected to the inner wall of the grooved ring 11; a guide post 13, one end of which is fixedly connected to one end of the positioning post 12, and the other end of which is fixedly connected to a top cover 14, both the positioning post 12 and the top cover 14 being slidably connected to the grooved ring 11; a terminal block 15, fixedly connected to the inner wall of the top cover 14, a support block 16 fixedly connected to the lower inclined surface of the grooved ring 11, and counterweight blocks 17 fixedly connected to both the upper and lower surfaces of the support block 16; and a tip 18, formed on the outer wall of the counterweight block 17. The vertical cross-section of the positioning post 12 is circular, the vertical cross-section of the guide post 13 is circular, and the outer walls of both the positioning post 12 and the guide post 13 are smooth surfaces.

The guide post 13 can support the positioning post 12, so that the groove ring 11 moves downward along the arc path on the top cover 14. The guide tube 10 drives the orifice tube 9 to move downward along the arc path, so that the liquid inlet at the top of the guide tube 10 is at the lowest point of the angle between the groove ring 11 and the top cover 14, and the installation position of the guide tube 10 can be automatically adjusted.

[0043] In this embodiment, as Figure 5 As shown, a battery 19 is fixedly installed on one side of the lead sleeve 7, and a wireless transceiver 20 is fixedly connected to one side of the battery 19. The wireless transceiver 20 is electrically connected to the infrared sensor 8 so that the battery 19 can power the wireless transceiver 20. When the infrared sensor 8 detects data of insulating oil leakage, it is wirelessly transmitted through the wireless transceiver 20. The wireless transceiver 20 has an anti-electromagnetic shell and can realize wireless data transmission operation in the ultra-high voltage environment.

[0044] In this embodiment, as Figure 4 As shown, a support bar 21 is fixedly connected between the collecting sleeve 3 and the annular column 5. A gap is provided between the support bar 21 and the lead sleeve 7 so that the collecting sleeve 3 can support the support bar 21. The support bar 21 provides support force to the annular column 5, ensuring that the annular column 5 can be used stably and increasing the stability of the annular column 5.

[0045] In this embodiment, as Figure 1 - Figure 6As shown, the bottom end of the terminal 15 is fixedly connected with the wire core 22, and the terminal 15 is fixedly connected with the terminal sleeve 1, and the wire core 22 is adhesively connected with the sealing ring 2; the bottom end of the sealing ring 2 is adhesively connected with the insulating sleeve 23, and the insulating sleeve 23 is fixedly connected with the limiting ring 4. An oil cavity 24 is formed above the sealing ring 2, and the oil cavity 24 is used to fill insulating oil. A plug column 25 is installed on the outer wall of the terminal sleeve 1 and close to the top end of the flow guide pipe 10, and the plug column 25 is inserted with the terminal sleeve 1. In order to adhesively connect the sealing ring 2 with the wire core 22 through sealing glue, adhesively connect the terminal 15 with the terminal sleeve 1 through sealing glue, and adhesively connect the inner wall of the limiting ring 4 with the insulating sleeve 23 through sealing glue, insulating oil is injected into the oil cavity 24, the plug column 25 is inserted with the terminal sleeve 1 to seal the edge, and the insulating oil is injected and packaged.

[0046] The working method of the extra-high voltage intelligent outdoor terminal is as follows:

[0047] Firstly, when the terminal is connected and installed, the sealing ring 2 is adhesively connected with the wire core 22 through sealing glue, the terminal 15 is adhesively connected with the terminal sleeve 1 through sealing glue, and the inner wall of the limiting ring 4 is adhesively connected with the insulating sleeve 23 through sealing glue. The insulating oil is injected into the oil cavity 24, the sealing glue is applied on the outer wall of the plug column 25, and then the plug column 25 is inserted with the terminal sleeve 1 to seal. The bottom of the insulating oil is sealed between the sealing ring 2 and the wire core 22, and the top of the insulating oil is sealed between the terminal 15 and the terminal sleeve 1. When the terminal 15 is rotated to a specified installation angle, the terminal sleeve 1 is also rotated to a specified installation angle, the wire core 22 is also rotated to a specified installation angle under the driving of the terminal 15, the insulating sleeve 23 is also rotated to a specified installation angle under the driving of the wire core 22, and the limiting ring 4 is also rotated to a specified installation angle under the driving of the insulating sleeve 23, and then the terminal 15 is inserted with the power supply terminal. The terminal 15 is fixedly installed by a bolt, and the bottom end of the wire core 22 is connected and installed with other power supply equipment.

[0048] Secondly, when the self-adjusting installation is carried out, under the action of the gravity of the lead sleeve strip 7, the lead sleeve strip 7 drives the sliding sleeve 6 to move downward along the circular arc path, the lead sleeve strip 7 drives the infrared sensor 8 to move downward along the circular arc path, the lead sleeve strip 7 drives the battery 19 to move downward along the circular arc path, and the battery 19 drives the wireless transceiver 20 to move downward along the circular arc path. At the same time, the collecting sleeve 3 supports the support strip 21, and the support strip 21 provides a supporting force for the circular ring column 5, so that the circular ring column 5 is kept stationary, so that the sliding sleeve 6 moves downward along the circular arc path guided by the outer wall of the circular ring column 5, until the lead sleeve strip 7 drives the sliding sleeve 6 to rotate to the bottom position. At this time, the infrared sensor 8 is at the lowest end position of the included angle between the collecting sleeve 3 and the limiting ring 4, and the terminal sleeve 1 can be installed according to the installation angle position of the terminal 15 and the core 22, so that the infrared sensor 8 can be automatically and intelligently installed to the lowest end position of the included angle, and the infrared sensor 8 detects the oil leakage problem at the lowest end position of the included angle.

[0049] At the same time, when the self-linkage installation is carried out, the two counterweights 17 and the support block 16 are counterweighted, so that the support block 16 and the counterweight 17 drive the sharp end 18 to move downward along the circular arc path, and the counterweight 17 and the support block 16 also drive the groove ring 11 to move downward along the circular arc path, the groove ring 11 moves downward along the circular arc path on the outer wall of the terminal sleeve 1, and the groove ring 11 slides along the outer wall of the positioning column 12. At the same time, the terminal 15 supports the top cover 14, the top cover 14 supports the guide column 13, the guide column 13 supports the positioning column 12, so as to ensure that the groove ring 11 moves downward along the circular arc path, and the groove ring 11 moves downward along the circular arc path on the top cover 14. The groove ring 11 drives the flow guide pipe 10 to move downward along the circular arc path, the flow guide pipe 10 drives the hole pipe 9 to move downward along the circular arc path, and the hole pipe 9 moves downward along the circular arc path with the sliding sleeve 6, so that the top end liquid inlet of the flow guide pipe 10 is at the lowest end position of the included angle between the groove ring 11 and the top cover 14. The terminal sleeve 1 can be installed according to the installation angle position of the terminal 15 and the core 22, so that the top end liquid inlet part of the flow guide pipe 10 is self-adjusted and installed to the lowest end position of the included angle of the oil leakage monitoring.

[0050] Finally, when the sealing ring 2 and the terminal sleeve 1 appear oil leakage, the insulating oil seeps into the gap between the insulating sleeve 23 and the sealing ring 2 along the gap between the sealing ring 2 and the wire core 22, and under the action of gravity, the insulating oil enters the lowest end position of the collection sleeve 3 and the limiting ring 4. The gap between the infrared sensor 8 and the limiting ring 4 is covered by the insulating oil, so that the infrared sensor 8 senses the leakage of the insulating oil. Or when the connection terminal 15 and the terminal sleeve 1 are connected, the insulating oil leaks from the connection terminal 15 and the terminal sleeve 1. The insulating oil drips to the lowest end position of the groove ring 11 and the top cover 14 along the inclined surface at the top of the terminal sleeve 1. The insulating oil enters the hole pipe 9 through the top inlet of the flow guide pipe 10, and drips to the lowest end position of the collection sleeve 3 and the limiting ring 4 from the hole pipe 9. The gap between the infrared sensor 8 and the limiting ring 4 is covered by the insulating oil, so that the infrared sensor 8 senses the leakage of the insulating oil. Realize intelligent automatic adjustment installation.
