Abstract
A leakage protection type internal oil vertical transformer corrugated oil storage tank comprises an oil storage tank outer cover, a corrugated core body and a bottom plate. The bottom plate is welded with the bottom plate which is welded with the outer cover or a protection coaming. Oil storage space where oil cannot leak downwards is formed among the corrugated core body, the bottom plate and the outer cover/the protection coaming, and organized oil drainage is achieved through a connection tube, and stainless steel materials are saved through a transition connection plate. According to the oil storage tank, the structure is used, so that once the corrugated core body leak, transformer oil can be retained in the oil storage space and cannot leak to drip on a transformer body. The oil storage tank is simple in structure, prior members are used to the largest extent, and secondary anti-leakage protection of the corrugated oil storage tank is achieved.
Description
Technical field
The utility model relates to the vertical bellow oil conservator of interior oil for a kind of transformer, belongs to electric power transformer insulated oil seal compensation arrangement technical field.
Background technology
Adopting stainless steel ripple core body is the renewal product of traditional rubber bag tank type oil conservator as the bellow oil conservator of cubage compensation element, but the ripple core body that stainless sheet steel is made because volume is large, wall thickness, weld seam be many, the danger of seepage and endurance failure is also very big, oily vertical structure bellow oil conservator particularly, once the seepage badly broken affects the transformer operation, even produce disaster hidden-trouble, this problem has caused the industry common concern.Existing procucts and declare patent and all do not relate to the leakage protection structural design in the market.
Summary of the invention
The purpose of this utility model is to provide a kind of leakage protection type bellow oil conservator with ripple core body seepage secondary protection function.
The purpose of this utility model is achieved through the following technical solutions: oily vertical transformer bellow oil conservator in a kind of leakage protection type; comprise oil conservator outer cover, ripple core body, base plate; it is characterized in that: described outer cover and base plate welding form the oil storage space of seepage downwards between ripple core body, base plate and outer cover.
Oily vertical transformer bellow oil conservator in a kind of leakage protection type; comprise oil conservator outer cover, ripple core body, base plate; it is characterized in that: welding protection coaming plate on the base plate between ripple core body and outer cover forms the oil storage space of seepage downwards between ripple core body, base plate and protection coaming plate.
The oil level indicating arm is connected to the corrugated regions of ripple core body.
Between ripple core body and outer cover, float switch is installed.
Be provided with the connecting leg with valve on base plate.
Be provided with stainless steel transition connecting plate between described ripple core body and base plate, the two ends of transition connecting plate respectively with base plate and ripple core body welded seal.
The beneficial effects of the utility model: the utility model adopts said structure, has changed the existing product outer cover and has only done the dust cover function, by outer cover and base plate welded seal, forms the oil storage space of seepage downwards between ripple core body, base plate and outer cover.Can also on base plate, weld the protection coaming plate that surrounds the ripple core body, realize forming the oil storage space of seepage downwards between ripple core body, base plate and leakage protection coaming plate.Once ripple core body seepage, transformer oil can be retained in oil storage space, can not leak, and water clock is to transformer body.The utility model is simple and reliable for structure, farthest utilizes existing member, has realized the antiseep second protection to bellow oil conservator.
The accompanying drawing explanation
Fig. 1 is the structural representation of a kind of execution mode of the utility model.
Fig. 2 is I partial enlarged drawing in Fig. 1.
Fig. 3 is the structural representation of the another kind of execution mode of the utility model.
Embodiment
Embodiment 1: oily vertical transformer bellow oil conservator in the leakage protection type; comprise oil conservator outer cover 1; the ripple core body 2 of transformer oil is housed; base plate 3; and the conventional connecting leg and the member that with ripple core body inside, communicate, as transformer tube connector 8, oil fuel tube 9, blast pipe 10 and support 11 and oil level window 12.By the bottom of outer cover 1 and base plate 3 welded seals, form the oil storage space A of seepage downwards between ripple core body 2, base plate 3 and outer cover 1.Once ripple core body 2 seepages, transformer oil can be retained in oil storage space A, can not leak, and water clock is to transformer body.
Float switch that can the increase checking leakage of oil in oil storage space A, float switch consists of ball float 13, trigger switch 14, and trigger switch 14 is connected with outer cover 1 or protection coaming plate 4, realizes the leakage of oil warning.
When ripple core body 2 welds with base plate 3, can also adopt transition connecting plate 6, be transition connecting plate 6 elder generations and base plate 3 welded seals, the oil pocket surface contacted with transformer oil during then to base plate 3 work is done application and is processed, and then by ripple core body 2 bottoms and transition connecting plate 6 welded seals.Transition connecting plate 6 can adopt corrosion resistant stainless steel material, and this structure has been saved the cost of base plate 3 employing stainless steel materials greatly.
Embodiment 2: oily vertical transformer bellow oil conservator in the leakage protection type; comprise oil conservator outer cover 1; the ripple core body 2 of transformer oil is housed; base plate 3; and the conventional connecting leg and the member that with ripple core body inside, communicate, as transformer tube connector 8, oil fuel tube 9, blast pipe 10 and support 11 and oil level window 12.Welding protection coaming plate 4 on the base plate 3 between ripple core body 2 and outer cover 1 forms the oil storage space A of seepage downwards between ripple core body 2, base plate 3 and protection coaming plate 4.The height of protection coaming plate 4 can be determined according to target and the cost requirement of leakage protection, usually be not less than 150mm.Float switch that can the increase checking leakage of oil in oil storage space A, float switch consists of ball float 13, trigger switch 14, and trigger switch 14 is connected with outer cover 1 or protection coaming plate 4, realizes the leakage of oil warning.
The more than one valvular connecting leg 5 of being with also can be set on the base plate 3 of oily vertical transformer bellow oil conservator in the leakage protection type of previous embodiment 1,2, and its effect is to open at ordinary times, realizes perflation ventilation.When ripple core body seepage, can find oil dripping by connecting leg 5, now can realize the leakage of oil protection by valve-off, also oil extraction prevents from polluting transformer in a organized way.
The height that improves ventilating opening subsidiary on outer cover and oil level window can increase the volume of second protection oil storage space, improves the protection effect, and in the time of even reaching the transformer maximum temperature, transformer oil does not overflow.In order to improve oil level window 12, need to dwindle oil level indication moving range, oil level indicating arm 7 and the tie point of ripple core body can be moved on to ripple core body 3 middle parts or bottom from the upper cover plate of ripple core body 3, and be connected or weld with the ripple place of ripple core body 3.
