In the electrical power industry, transformer maintenance and installation are crucial for ensuring stable operation of power systems. The 1000m³/h transformer vacuum drying machine, a high - efficiency device, is widely used in various scenarios. Here are the details:

I. New Transformer Installation

During new transformer installation, insulation materials may have absorbed moisture during manufacturing. The 1000m³/h transformer vacuum drying machine can form a vacuum around the transformer's core and windings, increasing the saturated vapor pressure of moisture in the insulation. Combined with heating, it promotes evaporation of moisture from the insulation paper. This ensures the transformer meets insulation standards before commissioning, preventing electrical breakdown caused by moisture and avoiding transformer failure. After drying, it can also be used for vacuum oil injection, removing bubbles and moisture from the oil, enhancing insulation and heat - dissipation efficiency, and ensuring stable transformer operation.

II. Transformer Maintenance and Repair

In the long - term operation of transformers, insulation materials are bound to accumulate moisture. During maintenance, the 1000m³/h transformer vacuum drying machine can remove moisture from insulation materials, restoring the transformer's insulation performance and reliability, thereby preventing insulation degradation and reducing the risk of transformer failure. Moreover, it can dehydrate insulating oil, removing free and dissolved water from the oil while maintaining its integrity, ensuring normal transformer operation.

III. Transformer Manufacturing Process

For transformers up to 100MVA, the 1000m³/h transformer vacuum drying machine can perform hot - air drying. By circulating heated air within the drying chamber, it evaporates moisture from transformer components. This method is simple to install, easy to operate, and cost - effective. As for transformers exceeding 100MVA, it can carry out the vapor phase drying (VPD) process. Operating under oxygen - free conditions at pressures of 0.1 - 0.2hPa, it transfers heat via solvent vapor, reducing drying time by over 50% compared to hot - air drying and ensuring thorough drying of large transformers to improve their quality.

IV. Transformer Tank Evacuation

During final transformer assembly, even if the active parts have been dried, insulation materials can re - absorb moisture within 18 hours. The 1000m³/h transformer vacuum drying machine can evacuate the transformer tank to an average pressure of 1hPa, effectively removing surface moisture and eliminating residual air pockets in the transformer's dead spaces. This prevents insulation degradation and ensures the transformer's sealing performance and insulation quality.

V. Transformer Oil Regeneration

The 1000m³/h transformer vacuum drying machine can be used with transformer oil regeneration systems to remove moisture, gases, and impurities from insulating oil. This restores the oil's insulation properties, improves regeneration efficiency, prolongs the oil's service life, and cuts operating costs.

VI. Drying of Other Electrical Equipment

In addition to transformers, the 1000m³/h transformer vacuum drying machine can vacuum - dry other electrical equipment like tap changers and auxiliary switches. It effectively removes moisture and gases, enhancing their insulation performance and reliability.

VII. Transformer Manufacturing and Repair Shops

In transformer manufacturing and repair workshops, the 1000m³/h transformer vacuum drying machine is an essential tool. By combining heating and vacuum technologies, it eliminates excess moisture from transformer windings, ensuring long - term stable equipment operation. For instance, the YUNENG 1000m³/h transformer vacuum drying machine has fast startup and air extraction capabilities, making it suitable for transformer vacuumization and also usable as a backing pump for large vacuum systems.

In summary, the 1000m³/h transformer vacuum drying machine is indispensable in the installation, maintenance, manufacturing, and drying of related electrical equipment for transformers. It plays a vital role in the electrical power industry.
