Background technology
At present, have a kind of horizontal outer oily oil conservator commercially for transformer configuration, its contour structures is metal cylinder, and wavy metal expander is that cylindrical, accumbency in cabinet, and is all immersed in oil, innerly communicates with air through pneumostome.Splendid attire transformer oil outside wavy metal expander and between cabinet, is communicated with oil tank of transformer by the pipeline of cabinet bottom, is reached for by the expansion of wavy metal expander and compression the object that transformer oil change in volume compensates.Find to there is following shortcoming through on-line operation in a few years:
1. cabinet is carbon steel material, wavy metal expander is equipped with back-up roller movable pulley, and motion middle pulley and cabinet inwall have sliding friction, therefore easily causes oil contaminated.
2. because wavy metal expander is a flexible body, unstable in transformer oil, need pulley support to lead, can not Complete Synchronization during motion, easily produce clamping stagnation.
3. the oil level of existing horizontal outer oily oil conservator need carry out two times transfer, the horizontal displacement of wavy metal expander is converted to the display of longitudinal oil level, not intuitively, accurately.
Utility model content
In view of existing horizontal outer oily oil conservator above shortcomings, the purpose of this utility model is to provide a kind of outer oil type metal bellow expansion oil storage tank.
The purpose of this utility model is achieved through the following technical solutions:
The utility model comprises cabinet and is arranged on the wavy metal expander in this cabinet, and the mid diameter of described wavy metal expander is greater than two ends diameter, and namely the diameter of this wavy metal expander is inside contracted to two ends by centre vertically; Described cabinet is tightly connected by pipeline road and oil tank of transformer, and this cabinet is interior, the outside of described wavy metal expander is filled with transformer oil, and the inside of described wavy metal expander is connected with ambient atmosphere by respiratory siphon; Described cabinet is provided with the gas exhaust piping for discharging cabinet internal gas.
Wherein: described wavy metal expander two up and down of being divided into shape identical, each described wavy metal expander is undergauge structure, namely diameter is inside contracted to the other end by one end, and one end that two described wavy metal expander diameters are larger is tightly connected, and is connected on the inwall of described cabinet; The axial cross section that upper and lower two described wavy metal expanders combine, centre is rectangle, and both sides are semicircle; Described cabinet has the oil level glass of oil level change in monitoring wavy metal expander; Described wavy metal expander does and longitudinally moves both vertically in cabinet, namely moves vertically; The axis of described cabinet and the axial vertical of wavy metal expander, the radial section of this cabinet is circular, oval or regular polygon; Described respiratory siphon is arranged on cabinet, and one end is connected with described wavy metal expander inside, and the other end is passed by described cabinet, is connected with ambient atmosphere; Described cabinet is provided with note drain line.
Advantage of the present utility model and good effect are:
1. the surface structure form of the existing traditional oil conservator of the utility model, the longitudinal direction realizing again wavy metal expander moves both vertically, and without the need to guiding, transformer oil can not be polluted.
2. wavy metal expander divides in order to upper and lower two by the utility model, is convenient to installing/dismounting; Upper and lower two wavy metal expanders are undergauge structure, avoid wavy metal expander doing in the process that longitudinally moves both vertically and clamping stagnation occurs.
3. the utility model is provided with oil level glass on cabinet, is convenient to the oil level change of monitoring in wavy metal expander.
Accompanying drawing explanation
Fig. 1 is internal structure schematic diagram of the present utility model;
Fig. 2 is that cutaway view is looked on a left side of Fig. 1;
Wherein: 1 is cabinet, 2 is gas exhaust piping, and 3 is wavy metal expander, and 4 is respiratory siphon, and 5 is pipeline road, and 6 is oil level glass, and 7 is note drain line.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1 and Figure 2, the utility model comprises cabinet 1 and is arranged on the wavy metal expander 3 in this cabinet 1, wherein the mid diameter of wavy metal expander 3 is greater than two ends diameter, and namely the diameter of this wavy metal expander 3 is inside contracted to two ends by centre vertically.
In order to easy accessibility, the wavy metal expander 3 of the present embodiment two up and down of being divided into shape identical, each wavy metal expander 3 is undergauge structure, and namely diameter is inside contracted to the other end by one end; Two wavy metal expanders 3 of the present embodiment are setting up and down, wavy metal expander 3 below being positioned at is inverted setting, and (the wavy metal expander being namely positioned at top is up-narrow and down-wide, the wavy metal expander being positioned at below is wide at the top and narrow at the bottom), the axial cross section that upper and lower two wavy metal expanders 3 combine, centre is rectangle, and both sides are semicircle.
The axis of cabinet 1 and the axial vertical of wavy metal expander 3, the radial section of this cabinet 1 is circular, oval or regular polygon (as regular hexagon or octagon); The cabinet 1 of the present embodiment is cylindrical, and radial section is circular.
One end that two wavy metal expander 3 diameters are larger is tightly connected, and is connected on the inwall of cabinet 1 both ends of the surface, does longitudinally vertical (namely vertically) motion in cabinet 1.Cabinet 1 is respectively equipped with gas exhaust piping 2 for discharging cabinet 1 internal gas and for noting the note drain line 7 of draining the oil, cabinet 1 is sealedly attached to oil tank of transformer by pipeline road 5, form hermetic oil piping system, be filled with transformer oil in cabinet 1, the outside of wavy metal expander 3 contacts with transformer oil.The inside of wavy metal expander 3 is connected with ambient atmosphere by respiratory siphon 4, and this respiratory siphon 4 is arranged on cabinet 1, and one end is connected with wavy metal expander 3 inside, and the other end is passed by cabinet 1, is connected with ambient atmosphere.
The either side end face of cabinet 1 has oil level glass 6, is convenient to the oil level change of monitoring in wavy metal expander 3.
Operation principle of the present utility model is:
When transformer oil temperature rise, transformer oil enters in cabinet 1 by pipeline road 5, and wavy metal expander 3 does and longitudinally moves both vertically, and wavy metal expander 3 expands.When temperature of oil in transformer reduces, transformer oil in cabinet 1 flows back to transformer by pipeline road 5, and wavy metal expander 3 shrinks, and is embodied as the compensation of transformer oil change in volume with the change of volume, be embodied as the object that transformer oil change in volume compensates, ensure the safe operation of transformer.Wavy metal expander, doing in the process longitudinally moved both vertically, because of the design of undergauge structure, avoids, in motion process, clamping stagnation occurs.
The material of wavy metal expander 3 of the present utility model is stainless steel.The surface structure form of the existing traditional oil conservator of the utility model, the longitudinal direction realizing again wavy metal expander moves both vertically, and without the need to guiding, transformer oil can not be polluted, and oil level instruction is directly perceived, accurate; For meeting the instructions for use of transformer, the contour structures of oil conservator can design according to actual needs.
