Detailed Description
As shown in fig. 1-4, the emergency disposal device under the situation of oil leakage of the box transformer substation is characterized in that the box transformer substation 1 is fixed on a civil engineering base 3, a waste oil collecting tank 5 which is closely attached to the civil engineering base 3 is arranged below a radiating fin 2 of the box transformer substation 1, the top of the waste oil collecting tank 5 is lower than the upper end face of the civil engineering base 3, a circle of blocking dam 4 with a gap is arranged on the civil engineering base 3 along the outer edge of the bottom of the box transformer substation 1, and the gap of the blocking dam 4 is converged at the waste oil collecting tank 5.
The part that probably takes place extensive oil leak is the fin that is located the case and becomes the outside, and used for promptly collecting waste oil when the great oil leak takes place in fin position mainly to be used, in consideration of be convenient for transportation and fire prevention requirement, the collecting vat is to be adopted polyvinyl chloride material to make, can drip into waste oil collecting vat 5 downwards when fin department oil leak, and the oil leak in other positions is collected to civil engineering base 3 downwards, and the oil body that leaks by the separation effect of barrage 4 is collected to the opening department and is got into waste oil collecting vat 5, and this kind of structure need not change original case and become the structure in a large number can realize the collection of oil body, realizes low-cost waste oil collection, environmental protection safety.
The bottom of the waste oil collecting tank 5 is connected with the input end of the oil pump 8, and the output end of the oil pump 8 is connected with the waste oil collecting barrel 9.
After the oil body in the waste oil collecting tank 5 is collected fully, the oil body can be pumped into the waste oil collecting barrel 9 through the oil pump 8 for collection, and the oil pump 8 and the waste oil collecting barrel 9 can be placed outside the cabinet body of the box transformer without occupying the space of the original box transformer cabinet body and changing the structure of the box transformer cabinet body.
The input end of the oil pump 8 is also connected with the box transformer 1 through an oil outlet joint group 7, and an electromagnetic valve 75 is arranged at the oil outlet joint group 7.
When the oil discharge is needed for the accident of the box transformer, the oil body in the box transformer is pumped to the waste oil collecting barrel 9 through the oil discharge port 73 by the oil pump 8 for collection.
The oil outlet joint group 7 comprises an oil pumping pipe 71 connected with the input end of the oil pump 8, the oil pumping pipe 71 is connected with a quick adapter 74 through an adapter flange 72, a quick hasp 76 is arranged on the quick adapter 74 and used for connecting an oil drain port 73, and an electromagnetic valve 75 is arranged on the quick adapter 74.
