Description

Technical Field

[0001] This utility model relates to the technical field of substation commissioning devices, specifically, to a substation installation and commissioning device. Background Technology

[0002] As the core hub of the power system, substations undertake important functions such as voltage transformation, power distribution, and power dispatch. During the installation and commissioning of substations, a series of complex operations are required, including precise equipment positioning, wiring inspection, insulation testing, and parameter calibration. These operations place extremely high demands on the load-bearing capacity, adjustment accuracy, adaptability, and safety protection performance of the equipment. In particular, grounding operations typically involve connecting a grounding wire to an insulated rod. The actual grounding operation is mainly done manually, using an insulated operating rod to hang the short-circuit grounding wire onto the equipment under maintenance or the conductor. This manual operation is difficult and highly dangerous.

[0003] To avoid the aforementioned problems, invention patent CN116505423A discloses a grounding device for substation installation and commissioning, belonging to the technical field of substation installation and commissioning equipment. It includes a movable base, with an electrical control device fixedly mounted above it. A vertically upward-pointing lifting column is also fixedly mounted above the movable base, with a vertically upward-pointing guide rod fixedly connected to the upper end of the lifting column. A horizontal pin is fixedly mounted at the upper end of the guide rod. An electric push rod is fixedly mounted above the movable base, electrically connected to the electrical control device. The telescopic rod of the electric push rod extends vertically upward, and a vertical insulating rod is connected to the upper end of the telescopic rod. A sliding groove is formed on the side wall of the insulating rod, which slides and engages with the horizontal pin. A clamping head is provided at the upper end of the insulating rod. By using the telescopic rod of the electric push rod to push the insulating rod upward, the insulating rod is raised, replacing the manual lifting operation of the insulating rod by workers. This allows for rapid lifting of the insulating rod and easy grounding of power lines or maintenance equipment at extremely high positions.

[0004] While the aforementioned technical solutions have their advantages, most current commissioning devices using clamping clamps still have some shortcomings in use. For example, the clamping clamps are difficult to open properly using a pull rope, or opening them becomes more difficult. Furthermore, due to height differences, it is not easy to ensure alignment when using clamps, affecting the proper connection of the short-circuit grounding wire. Therefore, we propose a substation installation and commissioning device. Utility Model Content

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0018] Please see Figures 1-5 This utility model provides a technical solution: a substation installation and commissioning device, including an outer frame 1 installed on an external maintenance vehicle, a scissor lift 10 installed on the top of the outer frame 1, a cylinder 2 fixedly installed on the platform 11 on the top of the scissor lift 10, an upper pad 25 provided on the telescopic shaft of the cylinder 2, a servo motor 26 fixedly installed on the top of the upper pad 25, a rotating shaft 261 fixedly installed on the output shaft of the servo motor 26, an insulating rod 27 detachably installed on the rotating shaft 261, an insulating sleeve rod 28 detachably installed at the end of the insulating rod 27 away from the rotating shaft 261, two symmetrical conductive rods 29 fixedly installed on the insulating sleeve rod 28, a cable 291 provided inside the insulating sleeve rod 28, and the conductive rods 29 connected to the corresponding cables 291.

[0019] In use, the conductive rod 29 is placed on external maintenance equipment or wires in conjunction with the cable 291 to perform a safe grounding operation; the end of the cable 291 is connected to an external grounding electrode box to ground any voltage that may accidentally appear on de-energized equipment and lines, ensuring the safety of personnel; in addition, the scissor lift 10 and the servo motor 26 work in conjunction with the cylinder 2 to enable the insulating rod 27 and the insulating sleeve rod 28 to achieve multi-dimensional adjustment of height, vertical position and rotation angle, and the conductive rod 29 is grounded through the cable 291 to ensure safety.

[0020] In this embodiment, the telescopic shaft of the cylinder 2 is provided with an insulating plate 21. Two symmetrical insulating seats 24 are fixedly installed on the top surface of the insulating plate 21. The bottom surface of the upper pad 25 is fixedly installed on the top between the two insulating seats 24, forming a multi-layer insulation structure. This allows the device to effectively block current when operating in a high-voltage environment, prevent electric shock accidents, and improve the safety of the debugging process.

[0021] like Figure 2 As shown, a steel plate 20 is fixedly installed on the telescopic shaft of cylinder 2. The steel plate 20 can be detachably installed on the bottom surface of insulation plate 21, which facilitates the replacement and maintenance of insulation plate 21, ensures that the insulation performance is always reliable, and avoids the impact of aging insulation components on safety.

[0022] like Figure 1 and Figure 2 As shown, a guide post 22 is fixedly installed on the bottom surface of the insulating plate 21, and a guide sleeve 23 is fixedly installed on the top of the platform 11. The guide sleeve 23 is fitted on the bottom outer side of the guide post 22 and is slidably connected to the guide post 22, so that the insulating plate 21 moves up and down more smoothly under the drive of the cylinder 2, reducing the impact of shaking on the debugging accuracy.

[0023] Specifically, a bearing seat 262 is fixedly installed on the upper pad 25. The end of the rotating shaft 261 away from the servo motor 26 passes through the bearing seat 262 and is rotatably connected to the bearing seat 262, which enhances the stability of the rotating shaft 261 during rotation, ensures the rotational accuracy of the insulating rod 27 and the insulating sleeve rod 28, and facilitates precise docking.

The arc-shaped support 271 is detachably installed on the outer wall of the rotating shaft 261 by locking screws, which facilitates the replacement of insulating rods 27 of different lengths or types according to debugging requirements, thereby improving the flexibility and adaptability of the device.

[0025] In addition, a rectangular groove 272 is provided on the top surface of the insulating rod 27, and a rectangular insert rod 281 is fixedly installed at the bottom center of the insulating sleeve rod 28. The rectangular insert rod 281 is inserted into the rectangular groove 272 for mating. The rectangular insert rod 281 and the insulating rod 27 are fixedly connected by multiple fastening screws, which makes the installation and disassembly of the insulating sleeve rod 28 simple and convenient to replace the insulating sleeve rod 28 with conductive rods 29 of different specifications to adapt to the debugging needs of different equipment.

[0026] It is worth noting that both the rectangular insert 281 and the rectangular slot 272 have rectangular cross-sections. The outer wall dimensions of the rectangular insert 281 are matched with the inner wall dimensions of the rectangular slot 272 to ensure a firm connection after insertion, preventing the insulating sleeve 28 from rotating or loosening during debugging, and ensuring stable contact between the conductive rod 29 and the equipment.

[0027] It is worth noting that the end of the conductive rod 29 away from the insulating sleeve rod 28 is in the shape of an arc hook, so that the end of the conductive rod 29 can be fitted onto the corresponding external cable.

[0028] Finally, it should be noted that the scissor lift 10, cylinder 2, servo motor 26, conductive rod 29, cable 291, external grounding electrode box, and other components involved in this utility model are all general standard parts or components known to those skilled in the art.

The specific connection methods should refer to the working principle of this utility model. The electrical connections between each electrical component are completed in the order of operation. The detailed connection methods are all technologies known in the art.

[0029] When using the substation installation and commissioning device of this utility model, first install the insulating plate 21 on the steel plate 20 of the cylinder 2 telescopic shaft with fastening screws, while ensuring that the guide post 22 is fitted into the guide sleeve 23, install the insulating rod 27 with arc-shaped support 271 on the rotating shaft 261, and then insert the rectangular insert 281 of the insulating sleeve rod 28 into the rectangular groove 272 of the insulating rod 27 and fix it with fastening screws; Connect one end of cable 291 to insulating sleeve rod 28 and the other end to external grounding electrode box. Operate scissor lift 10 to adjust the height of platform 11, start cylinder 2 to adjust the up and down position of insulating rod 27, and servo motor 26 drives rotating shaft 261 to rotate so that conductive rod 29 can accurately connect to external equipment or wires. After grounding is completed, debugging is carried out. After completion, the adjustment components are reversed, the insulating sleeve rod 28 and the insulating rod 27 are removed, the status of each component is checked, and then they are put away.
