We can often see that a large number of pebbles are placed under some transformers, so what are these pebbles for? Is it just for aesthetics?
Dry Transformer factory to explain to you.
This part under the transformer is generally called the oil discharge pool or the oil discharge pit (or similar name), leading to the oil pit or the oil pool. When there is an accident, such as oil injection, the oil of the transformer will be discharged into the oil discharge pit, and then flow to the oil pool. Some in the pool do the barrier, some do not do the barrier. To make a grating, the pebbles are placed on the grating; If no barrier is made, the pebbles are placed in the oil discharge pit. Do not do the barrier, with the transformer type, capacity, voltage level, there are provisions in this respect. This part of the oil-
Immersed Transformer is generally called oil unloading pool or oil unloading, leading to the end of the oil pit or the end of the oil pool. When there is an accident, such as oil injection and other problems, the oil of the transformer will flow into the oil unloading pit through the pebbles, and then flow to the end of the oil pool, then the pebbles under the transformer play a barrier effect, reduce the fire, conducive to rescue; Other high temperature transformer oil after cobble cooling, can reduce the fire.
The following seven factors are mainly considered under the placement of pebbles in the oil-immersed transformer:
Dry Type Transformer factory - after the transformer is used for a long time, the parts may have aging leakage and other problems, and placing a large number of pebbles can absorb the transformer oil leakage, so that the transformer oil can flow back to the oil pool smoothly, reduce the accident;
Dry transformer factory - once there is an accident, the pebbles can prevent the oil in the transformer from splashing and bursting.
Dry transformer factory - when burst fire, pebbles can play a barrier effect, prevent the fire from spreading to the ground, conducive to survival.
Dry transformer factory - subtle cooling effect, the transformer temperature is too high with the help of pebbles to cool it down.
Dry type transformer factory - cobblestone insulation, easy maintenance, operation personnel to check the operation.
Dry type transformer plant - Cobblestone has shock absorption effect. The effect is the same as a stone on a railroad, adding a layer of cushioning.
Dry transformer plant - prevent weeds from growing.
To prevent the transformer from catching fire when the oil is discharged to the ground, it will not block the oil discharge hole at the bottom of the oil discharge pit. Oil in the transformer cobblestone gap between the flow to the below, the surface to prevent oil pollution, oil leakage when it also plays the effect of cooling oil temperature, to prevent oil incineration.
