Distribution Type Transformer

• Kechang's Distribution Type transformer adopts high-quality low-loss silicon steel sheet iron core and all-copper wire winding design. By optimizing the magnetic flux density and winding arrangement, the no-load loss is reduced to below the national standard Level 1 energy efficiency limit, and the load loss is also greatly optimized.In daily operation, the precise control of iron loss and copper loss can save you considerable electricity bills every year.
• It fully complies with the requirements of the EU EcoDesign energy efficiency regulations. It is an ideal choice for high-efficiency low-loss transformer, suitable for long-term high-load operation of industrial plants and large-scale community power distribution projects.

• In the distribution network, short-circuit shocks caused by industrial equipment start-stop and line failures are the main causes of transformer damage. Once the failure occurs, it will cause large-scale power outages.The equipment adopts a winding structure optimized by dynamic analysis, and the high-voltage winding wires are automatically wound by the flattening process to enhance the mechanical strength; high-strength insulating materials are selected between the layers and the turns to ensure that the windings are tight and firm.
• After rigorous testing, it can easily withstand the impact of 31.5kA short-circuit current, and the level of partial discharge (PD) in key parts is controlled below 10pC, effectively avoiding failures caused by insulation aging.
• This reliable short-circuit-resistant design can build a strong line of defense for the stable operation of the distribution network and reduce the economic losses caused by unplanned downtime.

Your project may be distributed on outdoor construction sites, coastal salt spray areas or dusty industrial areas. The erosion of equipment in complex environments is a major problem.

This equipment has a protection level of IP54. The shell is made of hot-dip galvanized steel plate and welded by sealing. It is equipped with high-quality acrylate seals, which can effectively block dust intrusion and low-pressure water spray in any direction, and slow down the aging of the insulating oil.It can work stably in a wide temperature range of -25℃ to 45℃, and there is no need to reduce capacity within 2000 meters above sea level. It can operate reliably even in harsh environments with high humidity and windy sand. No additional protective facilities are required, which perfectly matches the application needs of IP54 weatherproof distribution transformer.

• In noise-sensitive places such as residential areas, commercial complexes, hospitals, etc., transformer operating noise is an important compliance indicator when purchasing.
• Kechang controls noise through a triple noise reduction design: high-quality core materials are selected and the self-vibration frequency is optimized. The core is manufactured by stepped joint technology to reduce magnetostrictive noise, and shock absorbers are installed to reduce operating vibration conduction.
• The operating noise of the final equipment is controlled below 45dB, which conforms to IEC noise standards. Even if it is installed in a power distribution room close to an office area or a residential area, it will not cause interference, and it can easily meet the requirements of densely populated places.

The operation and maintenance of traditional transformers rely on regular manual inspections, which makes it difficult to grasp the temperature rise status of the equipment in real time. High-temperature operation can easily accelerate the aging of insulation and bury safety risks.Distribution Type Transformer has built-in multiple PT100 temperature sensors to monitor the oil temperature of the iron core, winding and top layer in real time.The intelligent thermostat can automatically display temperature data, and automatically start the cooling system when the temperature is close to the warning value; sound and light alarms will be issued immediately when the temperature is over temperature.Through the MODBUS/RS485 protocol, you can also access the remote monitoring platform to realize remote real-time monitoring of temperature rise data, allowing you to predict the risk of failure in advance, change from "post-mortem maintenance" to "predictive maintenance", and significantly reduce operation and maintenance costs. This is the core value of smart temperature-monitored transformer.
