By adopting technique scheme, casing comprises that four side plates and a base plate form, on casing, be also provided with case lid simultaneously, on case lid lower surface, be also provided with the mounting groove suitable with side plate width, can can well be by side plate clamping by the mounting groove on case lid while making to install, during installation, can not misplace, the possibility that while having avoided installing, case lid is subjected to displacement, make better tightness, on mounting groove, be also provided with projection simultaneously, on side plate, be also provided with and the suitable stopper slot of projection simultaneously, case lid and side plate can better be installed, play the effect of second layer sealing, on projection, be also provided with projection simultaneously, projection can be conflicted and be connected with the groove on stopper slot, make both realize clamping, when having improved sealing simultaneously, when transformer oil expands with heat and contract with cold, case lid is squeezed also not can casing delamination, make equipment more stable, easy for installation, good airproof performance.
Of the present utility modelly further be set to: described mounting groove is also provided with raised line with respect to side plate one end, and described side plate outer surface is provided with the draw-in groove suitable with raised line, described raised line and the clamping of draw-in groove phase.
By adopting technique scheme, in mounting groove, be also provided with raised line, simultaneously at side plate and the suitable draw-in groove of raised line, make when mounted the projection on case lid and draw-in groove to be realized to clamping, increased the sealing between case lid and casing, also played stable limit function, case lid is more easily installed simultaneously, make structure more stable, improved the useful life being provided with.
Of the present utility modelly further be set to: described mounting groove is also provided with for the link slot of raised line is installed, and is also provided with elastic component between described mounting groove and raised line.
By adopting technique scheme, on mounting groove, be provided with link slot, be arranged on link slot in projection, link slot is connected with raised line by elastic component, make elastic component all the time that raised line and draw-in groove is inconsistent, increased the sealing of case lid and side plate, do not had under External force interference, case lid is difficult to be opened simultaneously, when people is dismounting, because the existence of elastic component can be separated with side plate by case lid, easy to operate easily, Stability Analysis of Structures.
Of the present utility modelly further be set to: described raised line cross section shape triangular in shape.
By adopting technique scheme, the cross section shape triangular in shape of raised line, draw-in groove shape is suitable simultaneously, make the raised line can be easily and exact separation or clamping, make can very easily case lid and side plate be realized to clamping when mounted, simultaneously also for convenience detach, simple in structure.
Of the present utility modelly further be set to: on described case lid and casing, be equipped with corrugate fin.
By adopting technique scheme, on case lid and casing, be provided with corrugate fin, case lid and casing are no longer single to pass through case lid and casing dispels the heat, and corrugate fin has increased the area of dissipation of case lid and casing, improve its radiating mode, effectively improved the heat-sinking capability of tank body of oil tank.
The utlity model has following advantage: the mounting groove on case lid and side plate clamping, projection and stopper slot clamping, this case lid and casing are easy for installation, and good airproof performance, is conducive to improve the useful life of equipment and the stability of work simultaneously.
