1. Product Overview: Core Characteristics of Emergency 11kV Transformers
Hubian Electric's emergency 11kV transformers are specially designed for urgent power supply scenarios, integrating the characteristics of high reliability, strong environmental adaptability, and quick installation. Different from conventional transformers, the emergency series products adopt a modular design concept and optimized structural layout, which not only ensures stable operation under harsh conditions but also greatly shortens the on-site installation and commissioning time. The product covers both oil-immersed and dry-type types, with a capacity range of 100kVA to 2500kVA, which can be flexibly selected according to the actual emergency power demand.
In terms of core component design, the iron core of the emergency 11kV transformer adopts high-grade grain-oriented silicon steel sheets with low loss and high magnetic permeability. The multi-level stepped lap structure and integral clamping technology are used to minimize magnetic flux loss and vibration noise, ensuring stable operation even under full-load emergency conditions. The windings are made of high-purity oxygen-free copper conductors, which are processed by vacuum pressure impregnation or epoxy resin casting technology. This not only enhances the insulation performance and mechanical strength of the windings but also improves their resistance to short-circuit impact. For oil-immersed models, high-quality transformer oil with excellent thermal conductivity and oxidation resistance is used, and the oil tank is equipped with an efficient cooling system to ensure that the transformer can operate continuously under high-temperature conditions. For dry-type models, a closed structure with IP54 protection rating is adopted, which can effectively prevent the intrusion of dust, moisture, and other impurities, adapting to various harsh outdoor emergency environments.
In addition, the emergency 11kV transformer is equipped with a complete protection and monitoring system. It integrates overcurrent protection, overvoltage protection, temperature protection, and other multiple protection functions. When an abnormal situation occurs during operation, it can quickly cut off the power supply to avoid equipment damage. At the same time, the transformer is equipped with a portable monitoring terminal, which can realize real-time monitoring of key parameters such as voltage, current, and temperature, facilitating on-site personnel to grasp the operation status of the equipment.
