1. Core energy saving and performance advantages
Compared with traditional dry transformers, the new generation of energy-saving models relies on material, structure and process upgrades to achieve energy saving and consumption reduction throughout the life cycle, and meet the goals of double carbon and cost reduction and efficiency enhancement.
- Low load loss, optimized loss by 10% to 15%, and significantly reduce long-term electricity bills.;
- The stability is full, and the trouble-free operation exceeds 100,000 hours, reducing the cost of downtime, maintenance and manual inspection, and adapting to continuous production.;
- It is equipped with an intelligent sensor module, which can remotely monitor load, temperature and other data to achieve refined energy-saving control;
- It is environmentally friendly and low-noise, oil-free and safer, and patented noise reduction technology reduces noise interference and is suitable for green factory construction.
2. Industrial application scenarios and selection points of dry transformers
Dry-type transformers cover substations, rail transit, mining and metallurgy, construction, petrochemical, communications, urban and rural power grids and other fields. The electricity consumption, environment, and operating requirements of different scenarios vary greatly. The selection needs to closely follow the four core parameters of voltage level, rated capacity, protection level, and insulation performance to match the special needs of the scenario, as follows：
(1) High-rise buildings and commercial complexes
Scene characteristics: dense personnel, strict fire prevention, small space, large load fluctuations, heavy safety and compactness.Selection points: Choose IP44 and above protection models to adapt to humid and dusty environments; reserve 10%-20% capacity margin according to the total load, and match low-noise models to reduce noise.
(2) Rail transit (railway/subway/light rail)
Scene characteristics: outdoor/tunnel operation, high vibration, dust, temperature difference, continuous and stable power supply is required.Selection points: the protection level is not lower than IP54, it is resistant to extreme environments and strong anti-interference; it is adapted to the system voltage, and the maintenance-free model is preferred to reduce the difficulty of operation and maintenance.
(3) Mining, metallurgy and chemical industry
Scene characteristics: There are many dust, corrosive gases, flammable and explosive media, large loads and strong impact.Selection points: customized models with anti-corrosion treatment of winding housings, with short-circuit capacity adapted to strong impact loads; oil-free and fire-proof models are preferred in closed scenes to build a strong safety line of defense.
(4) Communication base stations and data centers
Scene features: 24-hour uninterrupted power supply, extremely high reliability requirements, and urgent temperature control needs.Selection points: choose a high-reliability and long-life model to accurately match the capacity to avoid waste; it is equipped with a temperature-controlled cooling system to ensure the long-term operation of the equipment.
(5) Construction and transformation of urban and rural power grids
Scene characteristics: diverse scenes, scattered loads, heavy versatility, energy saving and cost-effective.Selection points: adopt low-loss and energy-saving models to match the appropriate capacity according to the load of the station area; choose IP54 and above protection models for outdoor installation to adapt to complex outdoor environments.
