Abstract
The utility model is a transformer oil tank double-sealing device, which comprises an upper tank edge of the tank body, a sealing joint strip stop board, a lower tank edge of an upper cover, a sealing joint strip, a bolt, a stop block, a sealing slot, a lower tank edge of a tank type upper cover and a lower tank edge of a bell jar type upper cover. The upper tank edge of the tank body and the lower tank edge of the upper cover are connected by the bolt and provided with the stop block and two sealing slots at the inner side of the bolt correspondingly arranged in the upper and the lower positions. Inside the two sealing slots are embedded with an inner and an outer butyronitrile sealing joint strip, between and out of which are provided with sealing joint strip stop boards. The lower tank edge of the upper cover is of tank type of bell jar type. The utility model provides a transformer oil tank double-sealing device with good sealing performance and without leakage caused by cracking and aging of the sealing joint strips.
Description
Affiliated technical field
The utility model relates to a kind of oil tank of transformer double seal, belongs to the transformer equipment technical field.
Background technology
The sealing device of oil tank of transformer is that the sealing joint strip 4 that a circle is made by the butyronitrile material is set between casing 1 and case lid 3 as shown in Figure 1 at present.The sealing adhesive tape is inlaid in the seal groove 7 that is arranged on casing 1 and the case lid 3, and sealing joint strip 4 both sides are provided with sealing joint strip limiting plate 2.This sealing joint strip be exposed half because of being subjected in the atmosphere progressively aging cracking of effect such as oxygen, illumination meeting, in case seepage will appear in aging cracking, this moment, transformer just needed to stop transport to repair, and changed sealing joint strip, and manpower but also influence ordinary production has not only wasted financial resources.In case just need return manufacturer's repairing as breaking down with the affixed then transformer of methods such as welding without sealing joint strip, loss is bigger like this, also is the unacceptable method of electricity consumption department.The sealing joint strip of being made by the butyronitrile material is not exposed at airborne second half and is difficult for impairedly, can use more than 30 years.
Summary of the invention
The purpose of this utility model is a kind of good seal performance of design, can not occur the oil tank of transformer double seal of seepage because of aging cracking.
The technical solution of the utility model is: a kind of oil tank of transformer double seal, and it includes casing top box edge, sealing joint strip limiting plate, loam cake nowel edge, sealing joint strip, bolt, guide vane end stop, seal groove, box loam cake nowel edge and bell-jar loam cake nowel edge; The casing top box is provided with guide vane end stop along being connected by bolt with loam cake nowel edge between casing top box edge and the loam cake nowel edge; It is characterized in that: the casing top box edge of bolt inboard and loam cake nowel along on have two circle seal grooves, two circle seal grooves corresponding setting on upper-lower position on casing top box edge and loam cake nowel edge, the inside and outside two circle butyronitrile material seal adhesive tape of setting-in are provided with the sealing joint strip limiting plate with the outside between two circle sealing joint strips in two circle seal grooves.
The utility model has the advantages that provides a kind of good seal performance, can not occur the oil tank of transformer double seal of seepage because of the sealing joint strip aging cracking.
