Abstract
The utility model relates to a device for cooling transformer oil, which comprises a refrigerating box and a thermoelectric couple, wherein the refrigerating box is mounted outside a transformer, and the thermoelectric couple is mounted inside the transformer. An input end of the refrigerating box is communicated with the transformer by the aid of an oil pipeline; an output end of the refrigerating box is communicated with the transformer by the aid of an oil return pipeline; and a self-priming pump and at least one valve are further mounted on the oil pipeline. The transformer oil is extracted from the bottom of the transformer and delivered into the refrigerating box, oil inside the refrigerating box is delivered to the upper side of the transformer and then returns to the refrigerating box, and all the oil inside the transformer can be subjected to circulation.
Description
Technical field
The utility model relates to a kind of device that is used for cooling transformer oil.
Background technology
Because when transformer moves under rated condition, factors such as the loss heating of iron core and winding, the rising of ambient temperature, load current increase all can cause the transformer oil temperature rise, and temperature of oil in transformer is when being higher than more than 95 ℃, just may cause some parts damages in transformer or the transformer, and the parts in the transformer are in case damage, at least needing has a power failure changes the damage parts, not only increases the operating cost of transformer, also brings certain difficulty to the user simultaneously.
In the prior art, for the temperature that prevents transformer oil raises, a kind of technical scheme is to utilize the blower fan of high speed rotating to provide cooling source for transformer, to reduce the oil temperature.Name as Chinese patent 2483812Y number bulletin is called " composite cooler of electric locomotive main transformer " and just provides a kind of scheme.This cooler comprises skeleton and is contained in intraskeletal water oil cooler, and water oil heating panel fin is housed on the water oil cooler, and air heating panel fin is contained in the place that facings the wind of composite cooler, and water oil heating panel fin is the trapezoidal spoiler of horizontal dual crossing.Though it is simple in structure that this kind reduces the device of oil temperature, cost of manufacture is lower, but because wind can only act on the transformer surface, transformer oil will could be realized heat radiation through the heat exchange with housing, so this kind device radiation speed is relatively slow, and because of blower fan must exist with exposed form, the variation meeting of external environment condition directly influences the heat sinking function of blower fan, so, utilize the blower fan heat radiation also to have certain problem.
Chinese patent 1588587A number the bulletin name is called the object lesson that " system and method for cooling transformer oil " provides water cooling transformer oil oil.This scheme has one or more distributor headers, and one or more gatherer head also comprises many cooling water pipes between distributor header and gatherer head, and is arranged on many cooling water pipe outer loop cooling water tanks.This patent is to adopt recirculated cooling water to come to be the transformer cooling, blower fan cooling relatively, though be subjected to the influence of external environment little, but the oil in water and the transformer is in carrying out heat exchanging process, need the transformer housing as intermediary equally, so the efficient of this kind cooling transformer oil mode is relatively low, and inefficient heat-exchange apparatus wastes energy.
Summary of the invention
The purpose of this utility model provides a kind of utilization allows the hydronic mode of transformer oil solve the device that is used for cooling transformer oil of problems such as energy waste.
The device that is used for cooling transformer oil that the utility model proposed comprises the refrigeration case that is installed in the transformer outside and is installed in the interior thermocouple of this transformer, the input of described refrigeration case is connected with transformer by oil pipeline, output is connected with transformer by oil returning tube, and self priming pump and at least one valve also are installed on oil pipeline.
The device that is used for cooling transformer oil that the utility model proposed adopts a thermocouple that is arranged in the transformer, when transformer oil reaches set point, thermocouple can pass to control device with temperature signal, send command signal by control device valve and self priming pump are opened, thereby turn back in the transformer again after making transformer oil by the refrigeration case forced cooling.
Because transformer oil is to be drawn out of from the transformer bottom to be sent in the refrigeration case, and the oil in the refrigeration case to be top from transformer turn back in the refrigeration case, can make the oil in the transformer all participate in circulation, so, this device cooling rate is fast, is not subjected to the influence of external environment during work.
Description of drawings
Accompanying drawing 1 is the surface structure schematic diagram of the embodiment of the device that is used for cooling transformer oil that proposes of the utility model.
Embodiment
Referring to Fig. 1, this figure provides the overall appearance structure of the embodiment of the device that is used for cooling transformer oil that the utility model proposes.This device comprises refrigeration case 1 and oil pipeline 2, and oil returning tube 3, and thermocouple (not providing among the figure) also is installed in transformer 4.
One end of described oil pipeline 2 is equipped with valve 21 and extends in the transformer 4, and oil pipeline 2 extends the outer position of transformer self priming pump 22 is installed, and the other end of oil pipeline 2 extend in the refrigeration case 1.Oil returning tube 3 is provided with three, and the two ends of each root oil returning tube 3 are connected with refrigeration case 1 transformer 4 respectively.
During this device busy, detect temperature oily in the transformer 4 by the thermocouple that is arranged in the transformer 4, when temperature reaches predetermined value, thermocouple can pass to temperature signal control device (not providing among the figure), send command signal by control device valve 21 and self priming pump 22 are opened, thereby make oil by turning back to again in the transformer 4 behind refrigeration case 1 forced cooling.
