Abstract
The utility model discloses a fuel tank sealing device of a transformer, which comprises the following components: an upper box edge of the box body, a lower box edge of the box body, a joint strip 1 which is equipped between the upper box edge of the box body and the lower box edge of the box body, and a joint strip positioning plate which is provided at one inner side of the joint strip. A groove is respectively provided on the upper box edge of the box body and the lower box edge of the box body. Furthermore the upper end and the lower end of the joint strip are respectively inserted into the grooves provided on the lower box edge of the box body and the upper box edge of the box body. The upper box edge of the box body is fixedly connected with the lower edge of the box body through a bolt. A joint strip 2 is provided between one side of the joint strip 1 and the bolt. The fuel tank sealing device of a transformer has the following advantages: reasonable designing, good sealing performance, prevention to the leakage phenomenon caused by cracking and aging of the joint strip, and reduced use cost.
Description
Technical field
The utility model belongs to the sealing device technical field, is specifically related to a kind of transformer oil box seal device.
Background technology
At present, the transformer oil box seal device is that the sealing joint strip that a circle is made by fourth eyeball material is set between casing and case lid, sealing adhesive tape top and bottom are inlaid in respectively in the seal groove that is provided with on case lid and the casing, and two inboards are provided with limiting plate about sealing joint strip, pass through bolt between casing and the case lid.A this transformer oil box seal device leakage side outside is because of being subjected to rayed and oxidation meeting aging cracking gradually for a long time, but not being exposed at airborne opposite side is difficult for impaired, can use more than 30 years, in case and the seepage phenomenon will appear in the transformer aging cracking, this moment, transformer just needed to stop transport to repair, change sealing joint strip, manpower but also influence ordinary production has not only wasted financial resources.If adopt method such as welding affixed without sealing joint strip, in case then transformer breaks down and just need return the repair in shop reason, lose greatlyyer like this, also be the unacceptable method of electricity consumption department.
The utility model content
The purpose of this utility model is to provide a kind of transformer oil box seal device at above-mentioned deficiency of the prior art, its reasonable in design, good seal performance, and avoided having reduced use cost simultaneously because of the seepage phenomenon appears in the sealing joint strip aging cracking.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of transformer oil box seal device, comprise casing top box edge, box cover nowel edge and be arranged on described casing top box along and the box cover nowel along between sealing joint strip one, and the sealing joint strip limiting plate that is arranged on described sealing joint strip one inboard, described casing top box edge and box cover nowel along on be provided with groove, and described sealing joint strip one top and bottom are inlaid in respectively in the groove on box cover nowel edge and casing top box edge, be bolted to connection between described casing top box edge and the box cover nowel edge, it is characterized in that: also be provided with sealing joint strip two between described sealing joint strip one outside and the bolt.
Described sealing joint strip one is the acrylonitrile-butadiene rubber bar.
Described sealing joint strip two is acrylate rubber bar or chlorohydrin rubber bar.
Described box cover nowel edge is box loam cake nowel edge.
Described box cover nowel edge is bell-jar loam cake nowel edge.
The utility model compared with prior art has the following advantages: the utility model is reasonable in design, good seal performance, it is by being provided with sealing joint strip two again between sealing joint strip one outside and bolt, and inner seal adhesive tape one adopts oil resistant and rebound performance excellence, but the acrylonitrile-butadiene rubber bar that ageing-resistant performance is relatively poor, outside sealing joint strip two adopts the ageing-resistant performance excellence, but acrylate rubber bar that rebound performance is poor slightly or chlorohydrin rubber bar, acrylonitrile-butadiene rubber bar by the inboard is born main sealing function, acrylate rubber bar or the chlorohydrin rubber bar secluding air and the sunlight etc. in the outside, guaranteed that inboard acrylonitrile-butadiene rubber bar can keep excellent sealing performance in 30 years, solve existing oil tank of transformer because of the problem of seepage phenomenon appears in the sealing joint strip aging cracking, reduced use cost simultaneously.
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
