When in actual use, when the oil body of burning flows to casing 1 department, the oil body of burning can be followed oil discharge portion and get into inside casing 1 to with fire-retardant granule 2 contact, and then realize fire-retardant fire insulation, the oil body after putting out the fire can be followed the mesh outflow of net spare 3 and collected.

In a second aspect, the embodiment of the application provides an oil storage tank is with fire-retardant system, include a plurality of oil storage tanks as above-mentioned with fire-retardant support, still include cell body 4, install the support frame 401 that is used for erectting a plurality of fire-retardant supports in the cell body 4, have cavity 402 between support frame 401 and the 4 bottoms of cell body, row oil well 403 has been seted up to the 4 bottoms of cell body, fire-retardant layer has been laid to the 4 bottoms of cell body. The tank body 4 is an oil tank arranged on the periphery of the transformer; the support frame 401 is erected in the tank body 4, the flame-retardant support is fully paved at the top of the support frame 401, the support frame 401 can obviously improve the bearing capacity of the flame-retardant support, the flame-retardant support does not need other installation procedures, only the flame-retardant support is placed at the top of the support frame 401, the period of site construction and paving is greatly shortened, the fully paved flame-retardant support can cover and seal the opening of the whole tank body 4, the design can ensure that the flame-retardant support in the path of the burning oil body can be subjected to primary fire extinguishing and then flows into the tank body 4 to be subjected to secondary fire extinguishing, the secondary fire extinguishing is realized by the flame-retardant layer paved at the bottom of the tank body 4, the burning oil body passing through the flame-retardant layer can be thoroughly extinguished and then is discharged and collected through the oil discharging 403 well, the design can greatly improve the fire extinguishing effect, and the re-burning situation of the oil body is avoided; the utility model has the advantages of fire insulation, flame retardation, oil leakage, water seepage, skid resistance, easy maintenance and cleaning, and strong bearing capacity, and can effectively meet the requirements of installation, operation, maintenance, overhaul, safety and the like; after the transformer fault accident, the burning is revealed to transformer burning explosion and oil body very easily takes place, the burning is revealed to oil body extremely irregularly all around, if the fire control facility equipment that sets up around the transformer also became invalid in succession after, along with the burning of transformer body and continuously reveal the transformer oil of burning, form the oil pool fire of lasting high temperature or the trickling fire of overflowing outside the oil pool easily, and cause the secondary calamity to take place, bring certain difficulty for the fire rescue, the system utilizes fire-retardant support and 4 cooperation realization fire-retardant of cell body, the function of oil seepage and infiltration, after the oil body infiltration fire-retardant support of irregularly revealing is to 4 bottoms of cell body, if there is the oil body of minimum probability still burning, the fire-retardant layer of laying of 4 bottoms of cell body, can realize secondary fire-retardant in cell body 4, reduce the whole cavity 402 temperatures in the bottom of oil pool, the oil body then through natural flow to in oil drain well 403, under the mechanism effect of double-deck fire extinguishing, the speed that the oil body flows has delayed greatly, for before the fire rescue reachs, strives for certain buffering time, in order to further expand, make the protection practicality higher.

In practical use, the burning oil body flows to the flame-retardant support, primary combustion extinguishing is realized through the flame-retardant support, the oil body which is not subjected to combustion extinguishing enters the pool body 4 to be accumulated, secondary combustion extinguishing is carried out through the flame-retardant layer, and the combusted oil body flows into the oil drainage well 403 to be collected.

The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
