Description
Technical field
Change the compensation device of volume the present invention relates to changing applied to the oil temperature in power system with transformer, have
Say it is a kind of internal metal bellow expansion oil conservator body.
Background technology
At present, commercially there is a kind of horizontal outer oily oil conservater for transformer configuration, its contour structures is metal cylinder
Body, wavy metal expander is circular configuration, is placed in housing, and is totally submerged in oil, through exhaling inside wavy metal expander
Suction inlet communicates with air；Transformer oil is contained between housing outside wavy metal expander, passes through the pipeline of lower housing portion
Connected with oil tank of transformer, the mesh of transformer oil Volume Changes compensation is reached for by the expansion and compression of wavy metal expander
's.Find to have the disadvantage that through on-line operation in a few years：
1. housing is carbon steel material, equipped with support rolling pulley on wavy metal expander, move in middle pulley and housing
Wall has sliding friction, therefore easily causes transformer oil and be contaminated.
It is 2. unstable in transformer oil, it is necessary to pulley support guiding, fortune because wavy metal expander is a flexible body
Complete Synchronization is unable to when dynamic, is also easy to produce clamping stagnation.
3. the wavy metal expander and housing of existing horizontal outer oily oil conservater need dual-seal to handle, welding bead is added
The hidden danger of leakage of oil；Wavy metal expander is not easy to find leak source, and hidden danger is brought to operation.
4. containing transformer oil in housing and directly being radiated by extraneous sunlight, easily make transformer oil temperature rise and aging,
Increase operating cost.
The content of the invention
In view of existing horizontal outer oily oil conservater above shortcomings, it is an object of the invention to provide a kind of inner oil type gold
Belong to bellow expansion oil storage tank.
The purpose of the present invention is achieved through the following technical solutions：
The present invention includes cabinet and the wavy metal expander in the cabinet, in the wavy metal expander
Between diameter be more than both ends diameter, i.e. the diameter of the wavy metal expander is inside contracted from centre to both ends vertically；The metal wave
The inside of line expander is tightly connected by pipeline road and oil tank of transformer, and the wavy metal expander, which is provided with, to be used to discharge
The gas exhaust piping of internal gas, the gas exhaust piping are passed by cabinet, are connected with ambient atmosphere.
Wherein：The wavy metal expander is divided into shape identical two up and down, each wavy metal expander
It is undergauge structure, i.e. diameter is inside contracted from one end to the other end, and one end that two wavy metal expanders are relatively large in diameter is close
Envelope connection, and be connected on the inwall of the cabinet；The axial direction that upper and lower two wavy metal expanders are combined together is cut
Face, centre are rectangle, and both sides are semicircle；The oil level of oil level change in monitoring wavy metal expander is provided with the cabinet
Observation window；The wavy metal expander does longitudinally perpendicular motion in cabinet, i.e., axially movable；The axial direction of the cabinet with
Wavy metal expander it is axially vertical, the radial section of the cabinet is circular, ellipse or regular polygon；The wavy metal
Expander passes sequentially through oil hose, pipeline road is sealedly attached to oil tank of transformer, is provided with the cabinet soft with oil transportation
The note drain line that pipe is connected；The material of the wavy metal expander is stainless steel.
Advantages of the present invention is with good effect：
1. being connected inside wavy metal expander of the present invention with oil tank of transformer, transformer oil is in wavy metal expander
Interior contacts with the inner surface of stainless steel, will not be by any pollution；Wavy metal expander does longitudinally perpendicular fortune in cabinet
It is dynamic, sanctioned by usage of the people to traditional oil conservater had both been ensure that, in turn ensure that the mode of wavy metal expander lengthwise movement.
2. wavy metal expander has been divided into two up and down by the present invention, dismounting is easily installed；Upper and lower two wavy metals
Expander is undergauge structure, avoids wavy metal expander and clamping stagnation occurs in longitudinally perpendicular motion process is done.
3. the present invention is provided with oil level glass on cabinet, it is easy to monitor the oil level change in wavy metal expander.
Brief description of the drawings
Fig. 1 is the internal structure schematic diagram of the present invention；
Fig. 2 is Fig. 1 left view sectional view；
Wherein：1 is cabinet, and 2 be wavy metal expander, and 3 be gas exhaust piping, and 4 be pipeline road, and 5 be oil hose, 6
It is note drain line for oil level glass, 7.
Embodiment
The invention will be further described below in conjunction with the accompanying drawings.
As shown in Figure 1 and Figure 2, the present invention includes cabinet 1 and the wavy metal expander 2 in the cabinet 1, wherein
The mid diameter of wavy metal expander 2 is more than both ends diameter, i.e., the diameter of the wavy metal expander 2 vertically from centre to
Both ends inside contract.
For convenient disassembly, the wavy metal expander 2 of the present embodiment is divided to for two above and below shape identical, each metal
Ripple expander 2 is undergauge structure, i.e. diameter is inside contracted from one end to the other end；Two wavy metal expanders of the present embodiment
2 is setting up and down, and underlying wavy metal expander 2, which is inverted, to be set (under narrow on wavy metal expander i.e. above
Width, underlying wavy metal expander are wide at the top and narrow at the bottom), the axial direction that upper and lower two wavy metal expanders 2 are combined together
Section, centre are rectangle, and both sides are semicircle.
The axial direction of cabinet 1 is axially vertical with wavy metal expander 2, and the radial section of the cabinet 1 is circular, ellipse
Or regular polygon (such as regular hexagon or octagon)；The cabinet 1 of the present embodiment is cylinder, and radial section is circle.
One end that two wavy metal expanders 2 are relatively large in diameter is tightly connected, and is connected to the inwall of the both ends of the surface of cabinet 1
On, longitudinally perpendicular (i.e. vertically) motion is done in cabinet 1.Wavy metal expander 2 passes sequentially through oil hose 5, petroleum pipeline
Road 4 is sealedly attached to oil tank of transformer, forms hermetically sealed oil piping system, is provided with what is be connected with oil hose 5 on cabinet 1
Note drain line 7.Gas exhaust piping 3 is provided with the top of wavy metal expander 2, for discharging inside wavy metal expander 2
Gas；The gas exhaust piping 3 is passed by cabinet 1, is connected with ambient atmosphere.
Oil level glass 6 is provided with any side end face of cabinet 1, is easy to monitor the oil level in wavy metal expander 2
Change.
The present invention operation principle be：
When transformer oil temperature rise, transformer oil enters wavy metal expander 2 by pipeline road 4, oil hose 5
Interior, wavy metal expander 2 does longitudinally perpendicular motion, and wavy metal expander 2 expands.When temperature of oil in transformer reduces, metal
Transformer oil in ripple expander 2 flows back to transformer by oil hose 5, pipeline road 4, and wavy metal expander 2 shrinks,
The compensation of transformer oil Volume Changes is embodied as with the change of volume, is embodied as the purpose of transformer oil Volume Changes compensation, is protected
Demonstrate,prove the safe operation of transformer.Wavy metal expander, because of the design of undergauge structure, is kept away during longitudinally perpendicular motion is done
Exempt from that clamping stagnation occurs in motion process.
Oil in wavy metal expander 2 can be discharged by noting drain line 7.
The material of the wavy metal expander 2 of the present invention is stainless steel.The present invention had both maintained the outward appearance of traditional oil conservater
Structure type, there is hermetically sealed, pressure-fired the working characteristics of inner oil type again, oil level instruction is intuitively, accurately；In order to meet transformation
The requirement of device, the contour structures of oil conservater can design according to being actually needed.
