Description

Technical Field:

[0001] The present invention belongs to the technical field of power system equipment, and particularly relates to a gas and particle separation and cooling system for transformer oil. Background Art:

[0002] A transformer is a very important device in the power system, and its normal operation depends on the good condition of each component. Among them, transformer oil, as an important component of the transformer, often contains oxygen and metal dust particles inside, and the temperature of the oil will rise as the equipment operates for a long time. However, when mixed with oxygen and particles, it will have a negative impact on the quality of transformer oil, thus affecting the operation of the equipment.

[0003] When the oxygen content in the transformer oil is too high, on the one hand, it will affect the decomposition of harmful components in the oil, accelerate the aging speed of the oil, and cause too many oxides to be generated in the transformer, damaging the equipment. On the other hand, the too high oxygen content will also cause the dielectric strength of the oil to drop sharply, thus affecting the insulation performance of the transformer. The metal dust particles in the transformer oil are in a suspended state and are difficult to separate from the oil. They are not sensitive to the metal content in the oil during the detection process, and it is also difficult to detect the metal content in the oil during the manufacturing and testing of high-voltage electrical products. Therefore, the metal dust particles in the oil constitute a potential pollution to the oil. In addition, too high an oil temperature will cause the transformer oil to crack into low-molecular hydrocarbons, resulting in a decrease in the flash point of the transformer oil. And the arc of partial discharge will carbonize the oil, deteriorating the insulation performance of the oil. When the average temperature of the transformer oil rises by 10°C, the deterioration speed of the oil increases by 2 times.

[0004] Therefore, we should pay attention to controlling the oxygen content and particle doping amount of the transformer oil, keep it within an appropriate range, and cool the oil in time to ensure the normal operation of the equipment. The present invention provides a gas and particle separation and cooling system for transformer oil to solve the above problems. Summary of the Invention:

[0030] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0031] As Figure 1 shown, the embodiments of the present invention provide a gas and particulate separation and cooling system for transformer oil, including an oil-gas separation device 2, a particulate separation device 3, a cooling device 4, and a circulation pump 9.

[0032] Among them, an oil inlet main pipe 5 is provided at the oil inlet end of the oil-gas separation device 2. The oil inlet main pipe 5 is communicated with seven oil outlet pipes 6 provided by the power heat source 1, and the oil temperatures in the seven oil outlet pipes 6 are the same or different. The oil outlet end of the oil-gas separation device 2 is connected to the oil inlet end of the circulation pump 9, the oil outlet end of the circulation pump 9 is connected to the oil inlet end of the cooling device 4, the oil outlet end of the cooling device 4 is connected to the oil inlet end of the particle separation device 3, and an oil outlet main pipe 7 is provided at the oil outlet end of the particle separation device 3. The oil outlet main pipe 7 is communicated with seven oil inlet pipes 8 provided by the power heat source 1. Both the oil outlet pipe 6 and the oil inlet pipe 8 are insulating cloth-covered silica gel pipes.

[0033] During application, under the action of the circulation pump 9, the oil discharged from the power heat source 1 sequentially enters the oil-gas separation device 2 through the oil outlet pipe 6 and the oil inlet main pipe 5. After removing the gas in the oil-gas separation device 2, it enters the cooling device 4 for cooling. The cooled oil enters the particle separation device 3 to remove metal dust particles. The oil after removing the gas and metal dust particles finally returns to the power heat source 1 through the oil outlet main pipe 7 and the oil inlet pipe 8 provided by the power heat source 1 for cyclic application.

[0034] As Figure 2 As shown, the oil-gas separation device 2 includes an oil-gas separation container 2-1, an inverter 2-2, and an air separation net 2-3. The oil-gas separation container 2-1 includes an upper pipe body and a lower pipe body that are detachably installed through a flange. The inverter 2-2 is a long cylindrical structure with an open top and a hollow interior. It is fixedly arranged inside the oil-gas separation container 2-1, fixedly connected to the upper pipe body, and the lower end of the inverter 2-2 extends to the lower part of the oil-gas separation container 2-1. The air separation net 2-3 is arranged inside the oil-gas separation container 2-1, and is fixedly connected to the inner wall of the upper pipe body of the oil-gas separation container 2-1 and the outer wall of the inverter 2-2 respectively, dividing the oil-gas separation container 2-1 into upper and lower spaces. The gas in the oil cannot pass through the air separation net 2-3. The oil inlet and outlet of the oil-gas separation container 2-1 are respectively arranged above and below the air separation net 2-3. The oil inlet main pipe 5 is a reverse U-shaped pipe. One branch pipe of the oil inlet main pipe 5 passes through the oil inlet of the oil-gas separation container 2-1 and extends to the lower inner part of the inverter 2-2, and the other branch pipe of the oil inlet main pipe 5 is distributed outside the oil-gas separation container 2-1 and is communicated with seven oil outlet pipes 6 of the power heat source 1 respectively.

[0035] During application, the oil discharged from the power heat source 1 sequentially enters the inverter 2-2 through the oil outlet pipe 6 and the oil inlet main pipe 5. The oil in the inverter 2-2 flows upward. The rising speed of the gas is greater than that of the oil, which can achieve the purpose of automatic separation. The bubbles formed when the gas flows upward are blocked by the air separation net 2-3. The gas is blocked above the air separation net 2-3, and the transformer oil enters the upper part of the air separation net 2-3 from bottom to top and moves to the lower inner part of the oil-gas separation container 2-1 through the air separation net 2-3, and finally flows out through the oil outlet for the next treatment.

[0036] AsFigure 2 As shown, the oil-gas separation device 2 further includes a one-way exhaust mechanism 2-4. The one-way exhaust mechanism 2-4 is connected to the oil-gas separation container 2-1 through a pipeline, and the connection end of the one-way exhaust mechanism 2-4 and the oil-gas separation container 2-1 is distributed above the gas separation net 2-3. A pressure sensor can be arranged inside the oil-gas separation container 2-1 to detect the internal pressure of the oil-gas separation container 2-1. When it is detected that the internal pressure of the oil-gas separation container 2-1 is higher than the set value, the one-way exhaust mechanism 2-4 is controlled by the control system to open, and the internal gas of the oil-gas separation container 2-1 is discharged through the one-way exhaust mechanism 2-4, avoiding excessive internal pressure of the oil-gas separation container 2-1 and achieving the function of stabilizing the pressure.

[0037] As Figure 2 shown, as a further preference of the present invention, the oil-gas separation device 2 further includes a breathing component. The breathing component includes a balloon 2-5, an air delivery pipe 2-6 and an air pump. Among them, the balloon 2-5 is arranged inside the oil-gas separation container 2-1, the air pump is arranged outside the oil-gas separation container 2-1, the air delivery pipe 2-6 passes through the air hole arranged on the oil-gas separation container 2-1, and the outer edge of the air delivery pipe 2-6 is sealed with the air hole of the oil-gas separation container 2-1. The two ends of the air delivery pipe 2-6 are respectively connected to the balloon 2-5 and the air pump. The air pump is used for inflating and deflating the balloon 2-5. When inflating, the balloon 2-5 expands and its volume becomes larger, and when deflating, the balloon 2-5 contracts and its volume becomes smaller. By controlling the inflation and deflation of the air pump, the internal pressure of the oil-gas separation container 2-1 can be adjusted, so as to achieve accelerated oil-gas separation.

[0038] As Figure 1 shown, the cooling device 4 includes a heat exchanger 4-1 and a refrigeration component. Among them, the heat exchanger 4-1 is provided with a refrigerant circulation pipeline and a heat exchange flow channel. The refrigerant circulation pipeline is used for the circulation of refrigerant (such as Freon), and the heat exchange flow channel is used for the circulation of transformer oil. The refrigeration component includes a compressor, a condenser, a liquid storage tank and an expansion valve. The outlet of the refrigerant circulation pipeline is connected to the compressor, the condenser, the liquid storage tank and the expansion valve in sequence through pipelines, and the expansion valve is connected to the inlet of the refrigerant circulation pipeline through a pipeline; the circulating refrigerant in the refrigerant circulation pipeline cools the hot oil in the heat exchange flow channel. The refrigerant after absorbing heat enters the compressor to form high-temperature and high-pressure gas, then enters the condenser to condense into liquid, and is stored in the liquid storage tank. The liquid refrigerant in the liquid storage tank enters the expansion valve for pressure reduction and temperature reduction, and then enters the refrigerant circulation pipeline again as a cold source to cool the hot oil in the heat exchange flow channel. Through such cyclic processing, the cooling and temperature reduction of the high-temperature oil are realized.

[0039] As Figure 3As shown in the figure, the particulate separation device 3 includes a stainless-steel pump housing 3-1, a first cathode 3-2, a second cathode 3-3, a U-shaped magnet 3-4, and seven anode cylinders 3-5.

The first cathode 3-2 and the second cathode 3-3 are parallel to each other, and the anode cylinders 3-5 are connected in series with each other and arranged between the first cathode 3-2 and the second cathode 3-3. The U-shaped magnet 3-4 is arranged outside the stainless-steel pump housing 3-1. The stainless-steel pump housing 3-1 is distributed between the two magnetic poles of the U-shaped magnet 3-4, and the U-shaped magnet 3-4 is used to provide a magnetic field. The oil processed by the oil-gas separation device 2 and the cooling device 4 enters the interior of the particulate separation device 3 through the oil inlet. The positive-ion particles fly towards the cathode plate, and the negative-ion particles fly towards the anode cylinders, so that the positive and negative charged particles in the oil are adsorbed inside the oil-gas separation device 2, and the oil after removing the particles is exported through the oil outlet.

[0040] As Figure 1 and Figure 4 shown, as a preferred embodiment of the present invention, a temperature sensor 10 and a pressure regulator 11 are arranged on the oil outlet pipe 6 of the power heat source 1 for detecting the oil temperature and the oil pressure.

Specifically, in this embodiment, the temperature sensor 10 includes a thermistor 10-1, a heat conduction cylinder 10-2, and an air interference prevention cover 10-3. The thermistor 10-1 is fixed inside the heat conduction cylinder 10-2 and sealed by the air interference prevention cover 10-3. The heat conduction cylinder 10-2 is fixed on the oil outlet pipe 6. The heat conduction cylinder 10-2 can immediately transfer the heat of the oil in the oil outlet pipe 6, and the thermistor 10-1 can sense the temperature of the oil in real time and feedback the temperature information to the main control system.

[0044] Among them, the oil barrel 12-1 is connected to the oil inlet main pipe 5 through the first oil pipeline 12-3. One end of the first oil pipeline 12-3 is connected to the lower end of the branch pipe of the oil inlet main pipe 5 of the inverted U-shaped pipe. The other end of the first oil pipeline 12-3 extends into the lower part of the oil barrel 12-1 through the oil outlet hole. The outer edge of the first oil pipeline 12-3 is sealingly connected to the inner edge of the oil outlet hole.

The other end of the second oil pipeline 12-6 passes through the oil inlet hole arranged on the oil barrel cover and is communicated with the oil barrel 12-1. And the outer edge of the second oil pipeline 12-6 is sealingly connected to the inner edge of the oil inlet hole. A makeup oil pump 12-7 is arranged on the second oil pipeline 12-6 for transferring the oil in the auxiliary oil barrel 12-2 into the oil barrel 12-1. When the oil quantity inside the circulation system is insufficient, start the oil transfer pump 12-4 and open the valve 12-5 of the oil pipeline. The oil in the oil barrel 12-1 enters the oil inlet main pipe 5 through the first oil pipeline 12-3. When the oil quantity in the oil barrel 12-1 is insufficient, start the makeup oil pump 12-7. The oil in the auxiliary oil barrel 12-2 enters the oil barrel 12-1 through the second oil pipeline 12-6.

[0045] As Figure 5 shown, as an alternative embodiment of the present invention, an oil return channel 12-8 is further arranged between the auxiliary oil barrel 12-2 and the oil barrel 12-1. Both ends of the oil return channel 12-8 are communicated with the auxiliary oil barrel 12-2 and the oil barrel 12-1 respectively. And an oil return valve 12-9 is arranged on the oil return channel 12-8. The oil inside the oil barrel 12-1 can also enter the auxiliary oil barrel 12-2 through the oil return channel 12-8.

[0046] The present invention can slow down the oxidation process of the oil, timely remove the particles in the oil to improve the impedance, dissipate heat efficiently, and increase the service life of the oil.
