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 wavy metal expander of existing horizontal outer oily oil conservator and housing need dual-seal process, add the hidden danger of welding bead leakage of oil; Wavy metal expander not easily finds leak source, brings hidden danger to operation.
4. splendid attire transformer oil and directly by the radiation of extraneous sunlight in housing, easily makes transformer oil temperature rise and aging, increases operating cost.
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 internal metal bellow expansion oil conservator.
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; The inside of described wavy metal expander is tightly connected by pipeline road and oil tank of transformer, and this wavy metal expander is provided with the gas exhaust piping for discharging internal gas, and described gas exhaust piping is passed by cabinet, is connected with ambient atmosphere.
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 wavy metal expander is sealedly attached to oil tank of transformer by oil hose, pipeline road successively, described cabinet is provided with the note drain line be connected with oil hose.
Advantage of the present utility model and good effect are:
1. the utility model wavy metal expander inside is connected with oil tank of transformer, and transformer oil only contacts with stainless inner surface in wavy metal expander, can not be subject to any pollution; Wavy metal expander does and longitudinally moves both vertically in cabinet, both ensure that the sanctioned by usage of people to traditional oil conservator, in turn ensure that the mode of wavy metal expander lengthwise movement.
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 wavy metal expander, and 3 is gas exhaust piping, and 4 is pipeline road, and 5 is oil hose, 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 2 in this cabinet 1, wherein the mid diameter of wavy metal expander 2 is greater than two ends diameter, and namely the diameter of this wavy metal expander 2 is inside contracted to two ends by centre vertically.
In order to easy accessibility, the wavy metal expander 2 of the present embodiment two up and down of being divided into shape identical, each wavy metal expander 2 is undergauge structure, and namely diameter is inside contracted to the other end by one end; Two wavy metal expanders 2 of the present embodiment are setting up and down, wavy metal expander 2 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 2 combine, centre is rectangle, and both sides are semicircle.
The axis of cabinet 1 and the axial vertical of wavy metal expander 2, 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 2 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.Wavy metal expander 2 is sealedly attached to oil tank of transformer by oil hose 5, pipeline road 4 successively, forms hermetic oil piping system, cabinet 1 is provided with the note drain line 7 be connected with oil hose 5.Gas exhaust piping 3 is provided with, for discharging the gas of wavy metal expander 2 inside on the top of wavy metal expander 2; This gas exhaust piping 3 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 2.
Operation principle of the present utility model is:
When transformer oil temperature rise, transformer oil enters in wavy metal expander 2 by pipeline road 4, oil hose 5, and wavy metal expander 2 does and longitudinally moves both vertically, and wavy metal expander 2 expands.When temperature of oil in transformer reduces, transformer oil in wavy metal expander 2 flows back to transformer by oil hose 5, pipeline road 4, wavy metal expander 2 shrinks, the compensation of transformer oil change in volume is embodied as 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.
Oil in wavy metal expander 2 is discharged by note drain line 7.
The material of wavy metal expander 2 of the present utility model is stainless steel.The utility model had both maintained the surface structure form of traditional oil conservator, had again the operating characteristic of hermetically sealed, the pressure-fired of inner oil type, and oil level instruction is directly perceived, accurately; In order to meet the instructions for use of transformer, the contour structures of oil conservator can design according to actual needs.
