Abstract
The utility model relates to a water-saving device of a circulating oil and water cooling system of an electric arc furnace transformer, which is characterized in that an electromagnetic valve (4) is arranged in the position of a water inlet pipe of a water cooler (3), an electric contact thermometer (2) is arranged in the position of an oil outlet b of the transformer, and a contact point ST of the electric contact thermometer is connected in an input loop of the electromagnetic valve (4) in series. When the transformer works, the electric contact thermometer (2) arranged at the circulating oil outlet detects the oil temperature at the outlet in real time, when the detected oil temperature is higher than 55 DEG C, the ST contact point of the electric contact thermometer is closed, and the water inlet electromagnetic valve (4) is opened for water to enter so as to cool a circulating oil coil pipe (8); and when the detected temperature of the electric contact thermometer (2) is lower than 45 DEG C, the water inlet electromagnetic valve (4) is closed automatically. The automatic device can reduce the using quantity of cooling water and ensure the working efficiency and the service life of the transformer.
Description
Technical field
The utility model relates to arc furnace transformer recycle oil water-cooling system, the particularly water saving fixtures of arc furnace transformer recycle oil water-cooling system.
Background technology
Transformer is a kind of typical electric equipment, especially for the zirconic transformer of melting, temperature can significantly raise during work, having a strong impact on the operating efficiency of transformer on the one hand, on the other hand, the too high Inside coil temperature that will make of temperature surpasses coil insulation thing heat resisting temperature, cause insulator too fast aging, so regulation transformer top-oil temperature degree is controlled at below 65 ℃, surpass this value, the life loss of 6 ℃ of transformer coil insulating varnish of the every rising of temperature doubles.
In order to cut the waste, improve the quality of power supply, promote transformer operating efficiency and life-span, usually transformer adopting recycle oil system is added water cooling, to reduce the transformer working temperature, reduce the recycle oil temperature by the compulsory type water-cooled, guarantee the transformer normal working temperature.And in real work, sometimes transformer load hour, the recycle oil temperature is lower, also needs a large amount of cooling waters this moment, waste is serious.
The utility model content
The purpose of this utility model just provides a kind of water saving fixtures of arc furnace transformer recycle oil water-cooling system, and it can satisfy the demand of transformer work cooling, using water wisely effectively again.
The purpose of this utility model is achieved in that
A kind of water saving fixtures of arc furnace transformer recycle oil water-cooling system, comprise transformer and the recycle oil coil pipe that links to each other, the recycle oil coil pipe is arranged in the water cooler, recycle oil coil pipe one end links to each other with the transformer oil-in, the other end links to each other with oil pump, oil pump links to each other with the transformer oil-out by oil pipe, the water inlet pipe place that it is characterized in that water cooler is provided with an electromagnetically operated valve, and transformer oil-out place is provided with electric contact thermometer, and the contact ST of electric contact thermometer is serially connected with in the input circuit of electromagnetically operated valve.
The utility model is provided with electric contact thermometer in the outlet of transformer recycle oil and belongs to known products commonly used, it can detect oil temperature in real time, when temperature is higher than design temperature point, and the electric contact thermometer ST closing of contact, entering water electromagnetic valve 4 is opened, and the recycle oil coil pipe is cooled.When temperature was lower than design temperature point, electric contact thermometer ST contact disconnected, and entering water electromagnetic valve 4 is closed.Therefore, the utility model does not promptly influence transformer operating efficiency and life-span, simultaneously, has saved cooling water amount again greatly.
Below in conjunction with embodiment and accompanying drawing the utility model is described.
Fig. 1 is for being the transformer recycle oil water cooling plant structural representation that the utility model provides.
Embodiment:
As shown in Figure 1, the water saving fixtures of the arc furnace transformer recycle oil water-cooling system that the utility model provides, comprise transformer 1 and the recycle oil coil pipe 8 that links to each other, recycle oil coil pipe 8 is arranged in the water cooler 3, recycle oil coil pipe 8 one ends link to each other with transformer oil-in a, the other end links to each other with oil pump 6, oil pump links to each other with transformer oil-out b by oil pipe 7, at the water inlet pipe place of water cooler 3 electromagnetically operated valve 4 is set, transformer oil-out b place is provided with electric contact thermometer 2, and the contact ST of electric contact thermometer is serially connected with in the input circuit of electromagnetically operated valve 4.Entering water electromagnetic valve is selected normally closed type unidirectional electrical magnet valve for use, controls entering of cooling water.In order to guarantee the needs such as maintenance of water cooler 3, the place is provided with conventional manual valve 5 respectively at the water cooler water inlet pipe and water outlet pipe.
During transformer work, make the circulation in closed pipeline 7, recycle oil coil pipe 8 and transformer 1 of transformer cooling oil by oil pump 6, install electric contact thermometer 2 additional in the recycle oil outlet, detect outlet oil temperature in real time, when electric contact thermometer 2 thermometrics are higher than 55 ℃, the ST closing of contact of electric contact thermometer makes the unlatching of entering water electromagnetic valve 4; When electric contact thermometer 2 probe temperatures are lower than 45 ℃, close electromagnetic water inlet valve 4 automatically.This automatics can reduce cooling water amount, guarantees the operating efficiency and the useful life of transformer.
