The application of pebbles in modern home.

Pebble floor is relatively rare in home decoration, and very few families use it as decoration around fireplaces and kitchen countertops. The reason why pebbles are not used much in home decoration may be that the cost is too expensive, the construction is complicated, the labor intensity is high, the construction cost is high, and the ground paved with pebbles is cold and hard, and it is uncomfortable to walk. The wide application of new decorative materials has brought new vitality to the pebbles, which are greatly appreciated because of their characteristics in decoration. The pebbles are stacked in a corner of the room, which adds a bit of vitality and nimbleness to the flowers hanging from the wooden fence wall. In terms of material, pebbles are smooth, hard, glossy and colorful. However, the wood floor is softer than pebbles, with dark color and poor gloss. Together, they are the beauty of natural harmony.

The place where cobbles are placed around the transformer foundation is generally called the oil unloading pool or oil unloading pit, leading to the accident oil pit or accident oil pool. In case of an accident, such as oil injection or, the transformer oil will be discharged into the oil unloading pit and then flow to the accident oil pool.

Some of the tanks are used as grids, while others are not. For grating, garden pebbles and machine-made pebbles are placed on the grating; The cobbles without grille shall be placed in the oil unloading pit. Whether to make a barrier or not depends on the type, capacity and voltage level of the transformer. There are regulations in this regard.

One reason is that cobblestones are placed to facilitate oil unloading. In addition, insulation, easy maintenance and inspection by operators are also reasons

（1） Transformer cobblestone standard

According to the standards issued by the Ministry of Construction, the lower part of the large oil immersed transformer should be equipped with an oil storage tank, with an area slightly larger than the plane occupied by the transformer, about - 1m, and cobbles with a diameter of 8-10cm should be laid to absorb oil leakage from the transformer.

Relevant standards: 50-80mm as specified in 7.3.4 of dl5027-1993, a typical fire protection code for electric equipment.

Article 5.4.5 of the Code for Design of 3-110kv High Voltage Distribution Equipment (gb 50060-92), the pebble layer with a thickness of not less than 250mm should be laid in the oil storage tank, and its diameter should be 50-80mm.

II. Related uses of pebbles

If it refers to the cobbles in the transformer oil pit, Jingdezhen cobbles are used for fire fighting. When the transformer is on fire, the transformer oil should be discharged quickly, and the oil flows to the bottom of the oil pit through the cobbles. Because the cobbles have the cooling and isolation functions, the accident will not be expanded.

If it refers to the cobblestone paved ground for the distribution equipment of the substation, it is to prevent rainwater from accumulating on the ground when it rains, which is not convenient for the operating personnel. Now many substations use concrete ground.
