Abstract
Enclosed dual-expansion mounth oil-water cooler, be mainly used in the cooling of transformer circulation cold oil, also can be used for the cooling of other similar devices cold oils, the utility model is provided with the enclosed isolation ward between oil cooling chamber and hydroecium, can combine in by oil, the water of oil cooling chamber and hydroecium seepage that this is indoor, help cleaning, can avoid oil, water because of seepage, mix the unsafe factor bring and the phenomenon of contaminated environment, be convenient to equipment inspection and maintenance, cooling water pipe is two bloated mouth structures, can effectively stop the profit seepage, and is simple in structure, effective, dependable performance, use, easy to operate.
Description
The present invention relates to the transformer oil-water refrigerating mechanism.
Transformer is when work, and its iron core and winding are because of the former of the function of current thereby heating, and especially high-power transformer is more outstanding.In order to make its operate as normal, need take the oil cooling cooling measure, when the circulation oil cooling, also need the oil of working is cooled off.Cooling common oil water-cooling apparatus to oil carries out cold by force to oil.Its cooling procedure and device have lower header (1), upper tank (2) referring to Fig. 1, are oil cooling chamber (3) between two hydroeciums, and cooling water pipe (4) passes the oil cooling chamber and is communicated with two hydroeciums.High temperature oil enters the oil cooling chamber by import, and in the process of flowing through, cooling water is taken away its heat, and cooled oil flows out through outlet, uses for the circulation cooling transformer.The hydroecium of existing oil-water refrigerating mechanism and the syndeton of oil cooling chamber are seen Fig. 2, are a dividing plate (7) between hydroecium (5) and oil cooling chamber (6), promptly so-called with being connected of dividing plate single bloated mouthful of cooling water pipe (8).During work, because cooling water and oil have certain pressure, then the oil or the water capacity are easily from the joint generation seepage of expand mouthful pipeline section and dividing plate, when oil infiltrates hydroecium, then cause whole circulation cooling water band oil, and bring the inconvenience or the environmental pollution of water system maintenance, when water infiltrates the oil cooling chamber, the oil of band water enters transformer and will cause unsafe factor, even has an accident.
The purpose of this invention is to provide a kind of enclosed dual-expansion mounth oil-water cooler, during this device busy, can prevent effectively that work oil, water from mixing, avoid the unsafe factor that brings because of seepage, avoid causing whole circulation water band oil because of oil seepage, but the oil or the water of seepage is combined in the enclosed isolation ward, do not produce excessive.
Technical scheme of the present invention is seen Fig. 1, establishes enclosed isolation ward (10) in the dividing plate (9) between hydroecium and oil cooling chamber, promptly establishes the enclosed isolation ward between hydroecium and oil cooling chamber, for the profit of collection storage seepage; Cooling water pipe passes this chamber, establishes hole (11) on the locular wall of enclosed isolation ward (10), for observing oil, seepage situation, is convenient to make, profit in the inspection and maintenance when using and the cleaning chamber.
Fig. 1 is a structure chart of the present invention, and is appointed as the specification digest accompanying drawing.
The invention will be further described below in conjunction with embodiment.
Embodiment presses structure fabrication shown in Figure 1,120 kilowatts of specified cooling capacities, and long-pending 13.5 square metres of active cooling surface, per hour 12 cubic metres of specified discharges, per hour 45 cubic metres of specified oily flows install high 1.87 meters.Cooling water pipe (4) all is provided with expand mouthful (12) with the section of cooperation of dividing plate (9) two plates, two bloated mouth structures, the mouth (12) that expands is to make with the roller electric tube expander in pipe and dividing plate assembling back, can make the pipe outer wall engage better with the dividing plate hole, can stop seepage oil or water effectively, between upper and lower hydroecium and the oil cooling chamber enclosed isolation ward be arranged all.The present embodiment cooling water pipe uses copper tube; Other each parts are the soldering group component.
The present invention is provided with the enclosed isolation ward between oil cooling chamber and hydroecium, can avoid the mutual seepage of profit to mix and the unsafe factor that brings, and the oil of seepage or water can combine in the enclosed isolation ward, are convenient to overhaul of the equipments, prevent the pollution of the environment; Cooling water pipe is two bloated mouth structures, can effectively stop oil, seepage, and is simple in structure, effective, dependable performance.Except that the cooling that can be used for the transformer cold oil, also can be used for the cooling of other similar devices cold oils.
Claims (2)
1, a kind of enclosed dual-expansion mounth oil-water cooler, comprise lower header, upper tank, oil cooling chamber, cooling water pipe and oil, water entrance, the oil cooling chamber is between upper and lower hydroecium, cooling water pipe passes the oil cooling chamber and is communicated with upper and lower hydroecium, it is characterized in that enclosed isolation ward [10] is arranged between hydroecium and the oil cooling chamber, on the locular wall of enclosed isolation ward [10] porose [11].
