Abstract
The present invention is aimed at providing a transformer oil conservator, it can be connected with a breather whose volume can be freely changed, they are formed into a closed system, which can be filled up with inert gas (for example N2). When the transformer oil volume is increased because the temperature in the oil tank is risen, the volume increment delta V can be transferred into the breather by means of connecting tube, the breather also can be isometrically expanded by delta V, so that between the oil conservator and breather a pressure balance state is formed, and the oil level change in oil conservator can be observed by means of oil-level gauge. Said breather has two structures: capsule type breather and metal float type breather.
Description
Affiliated technical field
The present invention relates to a kind of power transformer oil conservator.
Background technology
The effect of the transformer oil of oil-immersed power transformer is to guarantee the dielectric strength of transformer; Pass out the heat that transformer produces because of loss when operation; Slow down the aging of insulating material.In service at transformer, because the variation of ambient temperature and transformer load also changes the oily temperature of transformer oil within the specific limits, cause the volume of transformer oil also will change thus.When the effect of oil conservator will be satisfied the change in volume of transformer oil exactly, reduce and prevent that moisture and air from entering in the transformer, to delay the aging of transformer oil and insulating material.
Existing goods transformer oil conservator has: open type oil conservator, diaphragm type storage oil cabinet, capsule-type oil conservator and the multiple pattern of folded shape corrugated pipe oil tank.All there is different shortcomings in they.
The structure of open type oil conservator is the simplest, need not use easily aging barrier film and capsule, but dehydrating breather and periodic replacement hygroscopic agent need be set, and transformer oil will contact with air, impels transformer oil ageing.The structure of diaphragm type storage oil cabinet is the most complicated, though transformer oil does not contact with air, diaphragm of rubber directly contacts with transformer oil, and is aging easily, and changes trouble.The capsule-type oil conservator replaces barrier film with capsule, and structure is simple a little, and it is also easy a little to change, but transformer oil still contacts with air, also can impel transformer oil ageing, and dehydrating breather and periodic replacement hygroscopic agent need be set in addition.Folded shape corrugated pipe oil tank uses corrugated stainless steel tubing to replace barrier film and capsule, can overcome the problem of aging of elastomeric material effectively, but shortcoming be make trouble, cost is higher.
Summary of the invention
The object of the present invention is to provide a kind of tool to breathe the transformer oil conservator of gas container, it is by cabinet, oil filler, oil drain out, exhaust outlet, oil gauge, pressure gauge, with the oil tank of transformer connecting tube, formed with respirator connecting tube, support and structural member.It is characterized in that respirator is a confined space that volume can freely change, it by on the cabinet with being connected of respirator connecting tube, with the spatial communication more than the oil conservator pasta, constitute the system of a sealing, in this system, can be full of inert gas (N for example
2).When increasing when the volume Yin Wendu of the transformer oil in fuel tank rising, dilatation Δ V is through being delivered in the respirator with the respirator connecting tube, and respirator equivalent expansion Δ V makes between whole oil conservator and respirator to be in pressure balance.The pasta that can be observed the oil conservator from oil gauge changes.
Respirator has two kinds of structures, and a kind of is that the capsule-type another kind is the metal float bowl-type.
The invention has the beneficial effects as follows that simple in structure, cheap, installation side establishes; change easily, the life-span is grown (capsule-type respirator), life-span longer (metal float bowl-type); adopt inert gas shielding, can effectively delay the transformer oil deterioration, also need not to dispose dehydrating breather.
Description of drawings
The present invention is further illustrated below in conjunction with accompanying drawing.
Fig. 1 is the oil conservator front view, and Fig. 2 is the end view of Fig. 1, and Fig. 3 is a capsule respirator front view, and Fig. 4 is a metal respirator front view.Among the figure: 1 oil gauge, oily plane in the 2 oil conservator housings, 3 oil conservators, 4 with the respirator connecting tube, 5 pouring orifices, 6 exhaust outlets, 7 oil conservator cabinets lids, 8 sewage draining exits, 9 with the fuel tank connecting tube, 10. capsule-type respirator, 11 with the oil conservator junction pipe, 12 keg floats, 13 sealing oil, 14 metal respirator bases, 15 pressure gauges.
Embodiment
Referring to Fig. 1, oil conservator is by oil conservator shell 2 and oil conservator lid 7 containers that assemble, and oil gauge 1 and various interface are housed above, and what adopt among Fig. 1 is gage glass, also can adopt the liquid level meter (as float-ball type or magnetic-type etc.) of other model certainly.Connect with oil tank of transformer by taking over 9, the transformer oil pasta in the oil conservator is in 3 places, and the pasta upper space can be full of inert gas (as N
2), and link with the adapter 11 of respirator by taking over 4, so respirator and oil conservator constitute a closed system, because the volume of respirator can freely change, when transformer oil rises because of temperature rise is swollen, pasta 3 is risen, simultaneously inert gas is pressed in the respirator, the respirator equal-volume expands.Fig. 2 is the end view of Fig. 1, and oil gauge is loaded on the side, and it shows that high pasta corresponds to high oil temperature.Fig. 3 is the front view of capsule respirator, with oil conservator junction pipe 11 be with oil conservator on do not have to leak directly or by pipeline with respirator connecting tube 4 and connect, oily temperature in oil conservator is lower, capsule-type respirator volume is less, and capsule is the soft state of spraining, otherwise, oil temperature in oil conservator is higher, capsule-type respirator volume increases, and capsule is hard stile state, shown in double dot dash line among Fig. 3.Fig. 4 is the front view of metal respirator, on metal respirator base 14, the annular oil seal groove is arranged, wherein fill sealing oil 13 (for example transformer oil or silicone oil), keg float 12 back-offs wherein and can easy on and off drift along, with oil conservator junction pipe 11 be with oil conservator on do not have to leak directly or by pipeline with respirator connecting tube 4 and connect, oily temperature in oil conservator is lower, keg float 12 sinks, otherwise the oil temperature in oil conservator is higher, keg float 12 come-ups are shown in double dot dash line among Fig. 4.
Pressure gauge 15 is installed on the oil conservator, should keeps being close with ambient pressure.
Oil conservator answers frame more than oil tank of transformer, and respirator can also can be installed in below the oil conservator more than the oil conservator by frame.
