Description

Technical Field

[0001] The present invention belongs to the technical field of combined electrical equipment transportation, and in particular relates to a combined electrical equipment casing conductive rod transportation tool and a transportation method. Background Art

[0002] GIS combination electrical outlets primarily consist of bushing-type units and cable-type units. Due to shipping size constraints and potential quality issues associated with post-installation transportation, GIS units typically ship the bushings and main body separately. The bushing-type connection of the bushing-type unit utilizes a plug-in design, and the conductive rod extends beyond the bushing (porcelain bushing / composite insulation jacket) by a certain dimension. If shipped separately, the conductive rod must be shipped separately; otherwise, it will not support the bushing and cannot be transported with the bushing. Transporting the conductive rod separately requires reassembly of the bushing terminal block for on-site installation, requiring re-cleaning of the sealing surface. Complex on-site conditions can compromise the sealing performance. Furthermore, transporting the conductive rod separately without additional packaging can cause scratches and bumps, posing a risk to GIS operation. Summary of the Invention

[0003] In order to make up for the deficiencies of the prior art, the present invention provides a transport tooling and method for the conductive rod of the combined electrical casing, which solves the problems of inconvenient transportation, easy damage and difficult to ensure the quality of on-site installation of the conductive rod, realizes the overall safe transportation of the conductive rod and the casing, and reduces the workload and quality risks of on-site installation.

[0004] The present invention is achieved through the following technical solutions: A combination electrical appliance casing conductive rod transport tooling includes a casing, the upper end of the casing is connected to the casing conductive rod, and the casing conductive rod is characterized in that: the casing conductive rod is connected to a terminal block through a joint, the lower end of the casing is connected to the casing conductive rod transport tooling, a positioning sleeve for positioning the casing conductive rod is provided in the casing conductive rod transport tooling, and an inflation port is provided on the casing conductive rod transport tooling.

[0005] The casing conductive rod transport tooling is connected to the casing through a transition flange.

[0006] A first sealing ring is installed between the transition flange and the casing conductive rod transport tooling.

[0007] A second sealing ring is installed between the transition flange and the sleeve.

[0008] A shielding cylinder is installed on the transition flange.

[0009] A method for transporting a combined electrical appliance casing conductive rod is characterized by comprising the following steps: (1) Accurately install the shielding tube on the transition flange, install the second sealing ring in the sealing groove of the transition flange, and connect the transition flange to the sleeve; (2) Assemble the terminal block, connector and casing conductive rod, and connect the assembled casing conductive rod to the upper end of the casing; (3) Install the positioning sleeve in the casing conductive rod transport tooling and connect the casing conductive rod transport tooling with the transition flange; (4) Inflate through the inflation port, wrap and check for leaks after inflation, and adjust the gas pressure to 0.02-0.04Mpa after the leak test is qualified; (5) Place the installed casing and casing conductive rod transport tooling into the packaging box, set up buffer and fixing devices in the packaging box, and then transport it.

[0010] Preferably, in step (1), before installing the shielding cylinder on the transition flange, the shielding cylinder and the transition flange are inspected and cleaned to ensure that there are no impurities and oil stains.

[0011] Preferably, in step (1), the second sealing ring is wiped, silicone grease is evenly applied to the surface of the second sealing ring, and then the second sealing ring is installed in the sealing groove of the transition flange.

[0012] Preferably, in step (2), after the terminal block, the connector and the bushing conductive rod are assembled, the sealing surfaces of the bushing and the terminal block are cleaned to ensure that the sealing surfaces are clean, flat and free of any foreign matter.

[0013] Preferably, in step (4), during the wrapping and leak detection process, each sealing part is checked to ensure that there is no leakage. After the leak detection is completed, it is left to stand for 24 hours and then fully inspected again to ensure good sealing.

[0014] Preferably, in step (5), during the transportation process, the pressure changes inside the casing conductive rod transportation tooling are closely monitored to ensure that the pressure is always maintained at a slightly positive pressure state of 0.02-0.04 MPa.

[0015] The present invention provides the following beneficial effects: a dedicated transport fixture for the casing conductive rod is designed. The rod is directly connected to the connector and installed inside the casing. A positioning sleeve is installed within the transport fixture to support the rod, and the transport fixture is fixed to the flange via bolts. Furthermore, an air inlet is provided on the fixture, enabling leak detection during wrapping at a pressure of 0.4 MPa, meeting the requirements of sealing tests. This eliminates the risk of scratching the conductive rod and removing the decryption cover on-site, while also significantly reducing the installation workload for on-site service personnel.

DETAILED DESCRIPTION

[0018] The accompanying drawings illustrate a specific embodiment of the present invention. This embodiment includes a casing 1, the upper end of which is connected to a casing conductive rod 2, which is connected to a terminal block 4 via a connector 3. The lower end of the casing 1 is connected to a casing conductive rod transport fixture 5, which includes a positioning sleeve 6 for positioning the casing conductive rod 2. The casing conductive rod transport fixture 5 is also provided with an air inlet 7.

[0019] The casing conductive rod transport tool 5 is connected to the casing 1 via a transition flange 8. A first sealing ring 9 is installed between the transition flange 8 and the casing conductive rod transport tool 5. A second sealing ring 10 is installed between the transition flange 8 and the casing 1. A shielding cylinder 11 is installed on the transition flange 8.

[0020] The method for transporting the conductive rod of the combined electrical appliance casing of the present invention comprises the following steps: 1. Preliminary Preparation: Carefully inspect and clean the shielding tube 11 and transition flange 8 to ensure they are free of impurities and oil. Install the shielding tube 11 accurately on the transition flange 8. Carefully wipe the second sealing ring 10 and evenly apply silicone grease to its surface. Install it into the sealing groove of the transition flange 8 to ensure a good seal. After completing these steps, connect the transition flange 8 to the sleeve 1, ensuring a secure connection and a reliable seal.

[0021] 2. Conductive Rod Assembly: Assemble the terminal block 4, connector 3, and casing conductive rod 2 according to the design requirements. After assembly, carefully clean the sealing surfaces of the casing 1 and terminal block 4 to ensure they are clean, flat, and free of any foreign matter. Then, connect the assembled casing conductive rod 2 to the upper end of the casing 1. Strictly follow the operating procedures to ensure an accurate and stable connection.

[0022] 3. Fixture Installation: Install the positioning sleeve 6 within the casing conductive rod transport fixture 5. Ensure that the positioning sleeve 6 is positioned accurately and effectively supports the casing conductive rod 2. Next, clean the transition flange 8 and the sealing surfaces of the casing conductive rod transport fixture 5 again to ensure they are clean. After cleaning, connect the casing conductive rod transport fixture 5 to the transition flange 8 and tighten with bolts to ensure a tight connection without any looseness.

[0023] 4. Leakage Testing and Treatment: Inflate the pipe through the inflation port 7 on the conductive rod transport tool 5. Once the rated pressure is reached, perform a bandage test for leaks. During the bandage test, carefully inspect all sealing areas to ensure there are no leaks. After the leak test is complete, allow the pipe to stand for 24 hours and then perform another comprehensive inspection to ensure proper sealing. If the leak test is satisfactory, adjust the gas pressure to 0.02-0.04 MPa.

[0024] 5. Packaging and Transportation: Carefully place the installed casing 1 and casing conductive rod transport jig 5 into the packaging box. Install necessary cushioning and securing devices inside the box to prevent collision and displacement during transportation. During transportation, closely monitor pressure changes within the casing conductive rod transport jig 5 to ensure a constant, slightly positive pressure of 0.02-0.04 MPa. During on-site GIS assembly, simply remove the casing conductive rod transport jig 5 to conveniently proceed with the installation of the casing conductive rod 2 and casing 1.

[0025] The transport tooling and method for transporting the combined electrical appliance bushing conductive rod of the present invention have the following advantages: Simple and practical structure: The transport tooling structure is cleverly designed, easy to manufacture and install, and low cost.

[0026] Ensure transportation safety: The conductive rod and the casing are transported as a whole, avoiding possible damage such as scratches and bumps when the conductive rod is transported alone, ensuring that the quality and performance of the conductive rod are not affected.

[0027] Reduced installation risk: The number of times the bushing terminal block needs to be disassembled and assembled on site is reduced, which avoids contamination and damage to the sealing surface caused by the complex on-site environment, effectively reduces the risk of sealing performance problems, and improves the installation quality and reliability of GIS equipment.

[0028] Reduce workload: Greatly reduce the installation workload of on-site service personnel, improve installation efficiency, and shorten the construction period.
