Waterproof consideration for basic design and fabricationTop: Ventilation holes have effective rain-proof and water-proof capabilities;
Side: Carry out surface treatment for sides by waterproof concrete materials so that water can not penetrate from sides;
Bottom: Install waterproof concrete bearing base for buried transformer that is 300mm higher than the pit bottom.
At usual time, water flowing from the ground into the pit will enter the ring channel under the base so that it will not immerse the buried transformer. Lay sandy cobble at the bottom of the base so that water can penetrate into the ground more quickly.
Buried type transformer can also operate when immersing in water for more than 0.5m for a certain period of time. It can withstand floods and can effectively improve the reliability of the power supply system.
However, in order to ensure the safe and reliable operation of the transformer, it is suggested to check the water accumulation situation in the pit after floods and long time heavy rainfall and the rainy season.
If there is too much water, pumping and cleaning should be carried out.
Buried type transformer - temperature rise control measuresThe buried type transformer temperature rise control measures can be ensured by the following four ways: Transformer low temperature rise design, control the oil temperature at around 45K, far lower than the international regulated 60K; The design ideas are as follows: The heat load is directly proportional to the loss. Comparing with GB6451-1999, is 30% lower for the no-load loss and 15% lower for the load loss; Comparing with series 9, they are 20% lower for the no-load loss, so that their heat load is quite low. The naphthenic transformer oil is used so that the oil medium can flow freely at very low temperature without adding additive. Besides, the good viscosity-time property ensures the acceleration of oil flowing when the temperature rises to ensure the good cooling capacity of products. Tank structure the cooling of the buried type transformer oil tank manly relies on the radiation. The heat always radiate from the heater to the surrounding medium at lower temperature in form of wave. The radiation energy depends on the temperature, shape and surface color of the heater. As a result, the buried type transformer uses flat oil tank and plate heat sink to enhance the radiation. Surface treatment: Since the buried-type transformer is installed in the cool underground, special surface treatment technology is applied to ensure the good heat radiation capacity
