HERING VPT offers a comprehensive range of transformer drying technologies designed to meet the needs of various transformer sizes and specific requirements. Understanding these technologies is crucial for selecting the most suitable drying method for different applications.
For transformers with capacities up to 100 MVA, HERING VPT provides Hot-Air Drying Plants, which use heated air circulated within a drying chamber. The hot air evaporates moisture from transformer components, offering a cost-effective and straightforward solution ideal for smaller transformers. The simplicity of this setup makes it easy to install and maintain, ensuring reliable moisture removal without the need for complex equipment.
For larger transformers exceeding 100 MVA, HERING VPT employs Vapour-Phase Drying Plants. This method reduces the pressure inside the drying chamber, lowering the boiling point of water and allowing for more efficient and quicker moisture removal compared to traditional hot-air drying. The reduced drying time significantly enhances manufacturing and maintenance efficiency, making it a preferred choice for larger-scale operations where time and quality are paramount.
HERING VPT also offers Low-Frequency Electric Heating, suitable for applications requiring precise temperature control. This method uses low-frequency electric heating to generate heat evenly within the transformer, ensuring uniform temperature distribution. The consistent drying prevents hotspots, maintaining the integrity of transformer components and improving overall performance. This flexible approach can be applied to a wide range of transformer sizes and types, making it a versatile solution for different requirements.
Key Features of HERING VPT Vacuum Transformer Drying Ovens
HERING VPT's vacuum transformer drying ovens are engineered with innovative features to guarantee efficient operation, safety, and user convenience. The compact and modular design of these drying plants allows for quick installation and space-efficient setup. Each unit is pre-piped, wired, and pre-tested, streamlining the installation process whether performed by HERING VPT or the customer. The modular configuration also enables flexibility in scaling up or adapting the system to different facility sizes, maximizing space efficiency.
The advanced heating mechanisms and temperature control systems integrated into HERING VPT's ovens include wall heating systems and oil heaters with a capacity of approximately 200 KW. These systems use precision control elements like PLC systems and thermocouples to maintain accurate temperature regulation. The efficient heat transfer is facilitated by heating pipes within air channels, ensuring uniform distribution and optimal moisture removal.
To further enhance performance, the ovens feature high-efficiency vacuum systems equipped with rotary vane pumps and condensers. These components work together to effectively remove moisture, while safety mechanisms such as hydraulic door systems, control cabinets, and automated process controls ensure reliable and secure operation. The vacuum chambers are designed to withstand temperatures up to 200°C and are insulated with thick rock wool, which helps maintain consistent drying conditions and energy efficiency.
