Tank-opening work suna bukata a gine review. Review work suna bukata a gine assigned to dedicated personnel, especially to check tightness da internal screws. Idan haka, ana bukata a gine review marks on each screw, kafin haka person in charge ya gine final inspection. Tightening torque da bolts, suna bukata a gine applied as required by the manufacturer.Selection da usage requirements na lubricating greases da sealing greases wa:

• Lubricating greases da movable mechanical parts da electrical contacts inside GIS, suna bukata a select as required by the manufacturer.

• Layer da lubricating grease, suna bukata a gine not too thick.

• When using vacuum silicone grease for all "O"-ring seals and flanges, avoid applying it to the inner side of the "O"-ring seal that comes into contact with the SF₆ gas.

Technological requirements na disassembly da assembly sealing surfaces wa:

• Flange screws must be loosened diagonally along the circumferential direction.

• Sealing groove surface should not have scratches, and the sealing groove and flange plane should not rust.

• The grinding of damaged sealing groove surfaces should meet the manufacturer's requirements.

Technological requirements na replacing adsorbents wa:

• Adsorbents that are pre-treated and sealed-packaged at the factory can be used directly.

• Damaged or used bagged adsorbents must be dried before being installed.

• After the adsorbents are installed in the GIS, vacuum-pumping operations should be carried out immediately, and the time should be controlled within 30 minutes.

Technological requirements na vacuum-pumping wa:

• For disassembled gas chambers, pump to a vacuum of 40 Pa, continue pumping for 0.5 hours, stop the pump, and check the vacuum degree after 2 hours. If it is not more than 133 Pa, it is considered qualified. Fill with SF₆ gas to the rated pressure, and replenish the pressure in the depressurized gas chamber to the rated pressure.

• When detecting the vacuum degree, the McLeod gauge is strictly prohibited.

Technological requirements na filling SF₆ gas wa:

• When filling gas, first open the SF₆ gas cylinder and release a small amount of gas to prevent air from entering the GIS.

• Before use, the interface of the on-site gas-filling pipe should be cleaned, and after use, it should be properly stored and not placed on the ground to avoid introducing foreign objects during the gas-filling process.

• SF₆ gas cannot be directly filled into the gas chamber from the gas cylinder; it must be decompressed through a pressure-reducing valve.

• For SF₆ gas with sufficient micro-water content, the mass fraction of water should be less than 5×10⁻⁶, which is less than 40 μL/L when converted to volume ratio.

Technological requirements na local cover-type leak detection wa:

• The plastic cover (bag) should not have holes.

• All leakage points should be wrapped without omission.

• Detection personnel should be conscientious in detection, and the equipment and instruments should have good and reliable performance.

Inspection Work After GIS Equipment Installation

After the GIS equipment installation is completed, strict inspection and acceptance are required. Each component should be inspected in detail to ensure its quality and performance meet the standards. Then, a comprehensive inspection and test of the entire system should be carried out to ensure its normal operation and prevent potential safety hazards for users.

Only by carefully completing each step of the preliminary work can all tasks of subsequent work be successfully accomplished.

Effective Strategies for Optimizing GIS Equipment Installation Processes and Key Control Points
Implementing Safety Measures in GIS Equipment Installation

During the GIS equipment installation process, safety is a crucial aspect. To ensure the normal operation of the equipment and the safety of personnel's lives and property, a series of safety measures need to be taken, as follows.

Strengthening Inspection and Maintenance of GIS Equipment after Installation

• Pay attention to safety protection measures. During operation, relevant regulations and standards must be strictly adhered to. Appropriate personal protective equipment should be worn to avoid accidents. Meanwhile, management of the on-site environment should also be strengthened to prevent dust, oil stains, etc. from entering the interior of electrical components and affecting their normal operation.

• Monitor changes in equipment status. In daily use, attention should be paid to changes in the equipment's status, such as temperature rise and abnormal current fluctuations, so that corresponding measures can be taken in a timely manner.

• Maintain records and feedback. For any problems or defects discovered, timely recording and reporting should be carried out, and solutions should be submitted to relevant departments for improvement and refinement. Based on actual conditions, formulating a reasonable inspection and maintenance plan to enhance the safety performance and service life of the equipment is one of the important means to achieve efficient and stable operation of GIS equipment.

Improving the Quality Control of On-site Gas Filling for GIS Equipment

The inspection and maintenance requirements for gas pipelines are as follows:

• All connecting pipelines and connection components should be in good condition, clean, and free of oil stains. The connection between the pipeline and the product should be kept clean and can be wiped with lint-free paper dipped in alcohol.

• Before a pipeline that has been out of use for more than 10 days is reused, it needs to be purged and cleaned with high-purity nitrogen. After pipeline operations are completed, the connection heads should be sealed with plastic caps to prevent dust and foreign objects from entering.

Install filters at the gas-filling joints of pipelines to ensure the quality of gas filling.

Strengthening the Emergency Management of GIS Equipment

The specific measures for strengthening the emergency management of GIS equipment are as follows:

• In case of a malfunction, immediately stop the operation, notify relevant personnel for handling, and promptly contact the maintenance department or the technical support team of the manufacturer to resolve the issue quickly. In case of emergencies such as fires or explosions, evacuate the site as soon as possible to avoid casualties.

• In case of equipment damage, immediately stop the machine and notify the relevant department for handling. Meanwhile, isolate the damaged part to prevent other components from being affected. If necessary, temporary repair methods can be adopted to ensure the normal operation of the equipment.

• Pay attention to basic safety issues, such as the wiring method of electrical circuits and the selection of power supply voltage. In actual operation, strictly comply with relevant safety regulations and standards to ensure that the device can operate normally without endangering the surrounding environment.

Conclusion

In conclusion, during the installation process of GIS equipment, it is necessary to strictly comply with relevant standards and specifications to ensure the safe and stable operation of the equipment. At the same time, attention should also be paid to issues such as the connection methods and circuit layout between equipment to ensure the stability and reliability of the system. In addition
