The First Environmentally Friendly Pole Type Transformer

Compared with traditional transformers, the pole type transformer has been improved in all aspects in terms of production materials and processes, and has four major characteristics of environmental protection, high temperature resistance, stability and safety: First, environmental protection, the transformer innovatively uses vegetable oil as an environmentally friendly medium, and vegetable oil is natural The degradation rate can reach more than 97%. The second is high temperature resistance. The ignition point of the transformer insulating oil is above 350 ℃, which is more than twice that of conventional insulating oil. The third is stable operation. Since the high temperature resistance level of the transformer is much higher than that of conventional transformers, it can be applied to operating conditions with large peak-to-valley deviation, high three-phase unbalance rate or short-term overload operation. The fourth is safety. On the one hand, the transformer insulating oil has a high ignition point and is not prone to burnout accidents. On the other hand, in terms of structural design, the pressure relief valve nozzle can be adjusted downwards, which can meet the requirements of fire resistance from the structure and improve the safety and reliability of operation of pole type transformer.

In the next stage, our company will coordinate and supervise, continue to carry out the replacement of "green transformers" in the whole region, actively promote the transformation and upgrading of old equipment, continue to carry out digital operation and maintenance, drone line inspection and mapping and infrared temperature measurement, constantly. Improve the reliability of power supply, promote efficient use of pole type transformer energy, and focus on building energy-saving and low-carbon power grids in mountainous areas.
