Abstract
The utility model discloses an external water tank of a water-cooled transformer, which includes a water tank shell and an inner cavity formed by the shell; the shell is provided with a water inlet, a water outlet and a cooling water inlet communicated with the inner cavity, and at least a baffle; the baffle forms a flow channel used to reduce the flow speed of the cooling water entering from the cooling water inlet in the inner cavity; four baffles are arranged, which are respectively arranged on the two opposite sides of the shell and lined at intervals. Compared with the prior art, in the utility model, at least one baffle is arranged on the water tank shell; such baffles form the flow channel used to reduce the flow speed of the cooling water entering from the cooling water inlet in the inner cavity, so as to reduce the speed of the water flow after the flow direction of the hot water from the transformer cooler is led by the baffles, and achieve the goal of self temperature reduction. The external water tank further improves the temperature of the water in the water tank, so as to lay the foundation for the low-temperature operation of the water-cooled transformer.
Description
Technical field
The utility model belongs to the transformer accessory technical field, particularly a kind of outer tank that is applicable to the water-cooled dry-type transformer.
Background technology
Existing dry-type transformer is conventional air cooling equipment, this air cooling equipment is to be fixed in axial fan on the footing channel-section steel by startup, cold wind is discharged to the heat in the transformer running outside the transformer shell by the heat radiation air flue of transformer coil, thereby reaches the effect of cooling cooling.This cooling system just can be realized in transformer case inside, not need the external system support.Along with pushing forward comprehensively of China's modernization, the user is more and more higher to the requirement of product, especially for the transformer in some special industries and field, as marine transformer.The special different occasion of marine transformer requires the operating temperature of transformer can only reach about 45 ℃, and the transformer operating temperature that originally had air cooling equipment reaches 80～120 ℃, so original air cooling equipment has not reached client's demand, existing a kind of water-cooled transformer, by the recirculated water that outer tank provides the heat of transformer operation is exported by heat exchange, the well requirement of the transformer operating temperature that satisfies, but this cisten mechanism is simple, the hot water that is looped back by transformer directly transfers back to water tank again, the temperature of water tank is also promoted, thereby in follow-up process, cooling-down effect reduces.
Summary of the invention
The technical problem of solution that the utility model is pressed is at the deficiencies in the prior art, and a kind of improved outer tank that is used for dry type water-cooled transformer water-cooled cooling is provided, realize the purpose of the water temperature rapid and natural cooling in the water tank, thereby reach the whole circulation system fast cooling, make the significantly reduced effect of transformer operating temperature.
For solving the problems of the technologies described above, the following technical scheme of employing of the present utility model: comprise tank shell and the internal cavities that forms by housing, described housing is provided with water inlet, delivery port and the cooling water inlet that is communicated with internal cavities, described housing is provided with at least one baffle plate, and described baffle plate forms the runner that reduces the cooling water flow velocity that is entered by cooling water inlet together in internal cavities.
Described baffle plate is four, is separately positioned on the relative both sides of housing and is spaced.
Compared with prior art, the utility model is provided with at least one baffle plate on tank shell, these baffle plates form the runner that reduces the cooling water flow velocity that is entered by cooling water inlet together in internal cavities, thereby make the hot water of in transformer cooler, emitting after baffle plate is dredged flow direction, reduce the speed of current, thereby reach the purpose of cooling voluntarily.The utility model has further improved the water temperature in the water tank, for the cold operation of water-cooled transformer is laid a good foundation.
Description of drawings
Fig. 1 is the utility model structural representation.
Wherein 1 is that baffle plate, 2 is that tank shell, 3 is that delivery port, 4 is that water inlet, 5 is that cooling water inlet, 6 is internal cavities.
Embodiment
Below in conjunction with accompanying drawing, the utility model is elaborated, as shown in Figure 1, comprise tank shell 2 and the internal cavities 6 that forms by housing 2, described housing 2 is provided with water inlet 4, delivery port 3 and the cooling water inlet 5 that is communicated with internal cavities 6, described housing 2 is provided with at least one baffle plate 1, the quantity of baffle plate 1 is 4 in the present embodiment, be separately positioned on the relative both sides of housing 1 and be spaced, described baffle plate 1 forms a runner that reduces the cooling water flow velocity that is entered by cooling water inlet in internal cavities 6.Thereby after making the hot water of in transformer cooler, emitting dredge flow direction by this runner, reduce the speed of current, thereby reach the purpose of cooling voluntarily.
