Waterproof Measures for Buried Transformer
1. Waterproof consideration in foundation design and production Top: ventilation holes have effective rainproof and waterproof capability; Side: The side surface is treated with waterproof concrete material so that water seepage cannot invade from the side of the pit. Bottom: The waterproof concrete bearing base for installing buried transformer is 300mm higher than the bottom surface of the pit. At ordinary times, the water flowing from the ground to the pit flows to the annular road below the base and will not soak into the buried transformer.
2, the bottom of the foundation laying water sand pebble, water can quickly penetrate into the ground.
3. The buried transformer is allowed to run below 0.5m in water during the allowed period, which can resist floods and effectively improve the reliability of the power supply system. However, for the reliable operation of buried transformers, it is recommended to check the water accumulation in the pit after floods, long-term rainstorms and rainy seasons. If there is more water accumulation, it is recommended to pump water and clean it.
Buried transformer temperature rise control measures for buried transformer temperature rise control:
1, transformer low temperature rise design, top oil temperature control at about 45K, far lower than the national standard of 60K, design ideas. Box structure buried transformer oil tank wall heat dissipation mainly by radiation. Heat is always radiated in the form of waves from the heating body to the surrounding medium with lower temperature. The energy of the radiation depends on the temperature, the shape of the heating body and the color of its surface. Therefore, buried transformers are used for flat tanks and flat fins to enhance radiation.
2, surface treatment; Because the buried transformer body is installed under the cool surface, the surface treatment process is adopted to ensure that it has good heat radiation capacity and strong corrosion resistance.
3. The heat dissipation between the foundation and the outside world depends on heat conduction and air convection. Vents and air deflector can be set at the top of the foundation to strengthen air circulation.
