Specific embodiment
The invention will be further described with reference to the accompanying drawing.
As shown in Figure 1, the present invention includes cabinet body 1 and the ripple core 2 that is placed in the cabinet body 1, the inside of ripple core 2 is set
There is 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 designs
At, short transverse center line and ripple core 2 short transverse centerline collineation identical as the shape of upper sealing panel 3.
A connecting hole is provided 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
Spend the vertical bar of direction setting, transverse bar and the grid-shaped arrangement of vertical bar.The transverse bar and vertical bar and Sheng oil being arranged inside oil holder 4 hold
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, in oil holder 4 each space be connected to it is logical, and by being connected to inside check valve 11 and ripple core 2, therefore wave
Gas inside line core 2 can be by being discharged after oil holder 4 by the gas exhaust piping 6 that floor projection is located inside 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 body 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,
The oil level variation of oil conservater can be intuitively and accurately observed by the oil level glass 8 on cabinet body 1；The oil level of the present embodiment indicates
Device 7 can be oil level pointer.
The edge of the 3 axial cross section other side of upper sealing panel is equipped with feeler lever 14.Upper limit is respectively equipped on the inner wall of cabinet body 1
Alarm switch 13 and lower limit alarm switch 12, the upper limit alarm switch 13 and lower limit alarm switch 12 be located at feeler lever 14 with
On the path that ripple core 2 is gone up and down.
The working principle of the present embodiment are as follows:
Lower surface installation shape with upper sealing panel 3 identical oil holder 4 structure of the present invention using upper sealing panel 3, wave
The inside of line core 2 inside check valve 11 and oil holder 4 by being connected, because the height of oil holder 4 is equal to ripple core 2
Height when closure, therefore pressure protective device can be played the role of.Oil of the ripple core 2 before transformer station high-voltage side bus when oiling is logical
It crosses check valve 11 to be injected into oil holder 4, the oil of self weight and the injection of oil holder 4 overcomes oily in ripple core 2
Buoyancy, and the oil holder 4 can generate micro-positive pressure to ripple core 2, and transformer is made to keep the work of micro-positive pressure at runtime
State.Once pipeline road 10 leaks, the oil in ripple core 2 understands gradually light leakage, and the oil in oil holder 4 will not leak
Fall, oily weight can force ripple core 2 to be closed in oil holder 4, and then lower limit alarm switch 12 is made to alarm, to guarantee
The safe operation of entire voltage transformer system.Moreover, the oil holder 4 of the present embodiment no matter in 2 internal positive pressure of ripple core or
When negative pressure, upper sealing panel 3 can be protected indeformable.
