Specific implementation mode
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in Figure 1, the utility model includes cabinet 1 and the ripple core 2 that is placed in the cabinet 1, ripple core 2 it is interior
Portion is equipped with oil holder 4, which is mounted on the lower surface of upper sealing panel 3；The shape of the oil holder 4 of the present embodiment
It has been designed to, short transverse center line and ripple core 2 short transverse centerline collineation identical as the shape of upper sealing panel 3.
Connecting hole there are one being opened on the side plate of oil holder 4, aperture is identical as pipeline road 10, which is mounted with
The check valve 11 that can only be flowed into oil holder 4.For ripple core 2 before transformer station high-voltage side bus when oiling, oil passes through check valve 11
It is injected into oil holder 4, oil holder 4 forms micro-positive pressure to the ripple core 2.
As shown in Fig. 2, being separated into multiple spaces by stud 5 in oil holder 4, through-hole 15, each sky are provided on the stud 5
Between by the through-hole 15 be interconnected.Stud 5 divides transverse bar to be arranged along 4 length direction of oil holder and wide along oil holder 4
The vertical bars of direction setting are spent, transverse bar is in latticed arrangement with vertical bars.The transverse bar and vertical bars that 4 inside of oil holder is arranged hold with oil is contained
4 collective effect of device, can effectively prevent the deformation of upper sealing panel 3.The height of oil holder 4 is equal to height when ripple core 2 is closed
Degree.
As shown in Figures 1 and 3, it is respectively equipped on upper sealing panel 3 and 2 inside of ripple core and 4 inside phase of oil holder
The gas exhaust piping 6 of connection, for the gas inside 2 inside of ripple core and oil holder 4, the two gas exhaust pipings 6 to be discharged
The floor projection of position is located at the outside of 4 inside of oil holder and oil holder 4 and in ripple core 2
Portion；That is, each space is connected to logical in oil holder 4, and it is connected to by check valve 11 and the inside of ripple core 2, therefore wave
Gas inside line core 2 can be discharged by the gas exhaust piping 6 being located inside oil holder 4 by floor projection after oil holder 4；
Meanwhile the gas inside ripple core 2 can also be located at the outside of oil holder 4 and in ripple core 2 by floor projection
The gas exhaust piping 6 in portion is discharged.The lower sealing plate 9 of ripple core 2 is equipped with the pipeline road 10 being connected to oil tank of transformer, is formed
Real hermetically sealed oil piping system.
Oil level indicating device 7 is installed at the edge of 3 axial cross section side of upper sealing panel, cabinet 1, which is equipped with, observes the oil
The oil level glass 8 of position instruction device 7, oil level indicating device 7 are located at close to the side of oil level glass 8.Product at runtime,
