Description

TECHNICAL FIELD

[0002] A transformer is the most core device in all power equipment. The transformer is expensive and usually runs for decades. Once a fault occurs, it will cause partial or large-area power outage of a power grid. It is of great significance to prevent large-scale power outage accidents to perform predictive maintenance on an oil-immersed transformer and to early detect and treat possible problems of the transformer. To achieve the predictive maintenance on the transformer, some state parameters of the transformer during operation must be monitored, and then the operation state of the transformer equipment is judged through changes of the transformer. Related parameters of dissolved gases in oil of the oil-immersed transformer can well represent the working condition of the oil-immersed transformer equipment.

Figure 2 This is an electrical schematic diagram of the dual-chamber vacuum spray oil degassing device in the dual-chamber vacuum spray oil degassing method described in the embodiments of this application.

[0048] This application provides a dual-chamber vacuum spray oil degassing method, which is applied to a dual-chamber vacuum spray oil degassing device.

[0049] likeFigure 2 As shown in this embodiment, the dual-chamber vacuum spray oil degassing device includes a first oil chamber 10, a second oil chamber 20, a drive element 30, a gas collection tank 40, and a control module. One end of the drive element 30 is connected to the first oil chamber 10 and the second oil chamber 20 respectively through pipes having a fifth control valve 105 and a fourth control valve 104. The other end of the drive element 30 is connected to the oil outlet through a pipe having a sixth control valve 106. The first channel 1 of the fifth control valve 105 is connected to the oil inlet through a pipe. The first oil chamber 10 and the second oil chamber 20 are connected by a pipe having a third control valve 106. The control valve 103 is connected to the pipeline. The outlet of the first oil chamber 10 is connected to the gas collection tank 40 through the pipeline with the first control valve 101. The first oil chamber 10 is connected to the first channel 1 of the third control valve 103, the first channel 1 of the fourth control valve 104, and the third channel 3 of the sixth control valve 106 through the pipeline with the second control valve 102. The control module controls the operation of the drive element 30, the first control valve 101, the second control valve 102, the third control valve 103, the fourth control valve 104, and the fifth control valve 105 according to the dual-chamber vacuum spray degassing method.

[0050] It should be noted that the first oil chamber 10 is divided into an oil chamber and a degassing chamber. The oil chamber is located at the bottom of the first oil chamber, and the degassing chamber is located above the oil chamber. Both the first oil chamber 10 and the second oil chamber 20 are used to store oil. Both the first oil chamber 10 and the second oil chamber 20 are rectangular parallelepipeds, with cylindrical interiors. Both are made of aluminum alloy with smooth inner walls. The driving element 30 can be a unidirectional magnetic oil pump. The driving element 30 is used to supply and drain oil to the first oil chamber 10 and the second oil chamber 20. In this embodiment, the volume of the second oil chamber 20 is not less than half the volume of the first oil chamber 10. Using a unidirectional magnetic oil pump as the driving element facilitates control of the oil inlet and outlet speeds in this dual-chamber vacuum spray oil degassing device, and the unidirectional magnetic oil pump has good sealing performance, meeting the requirement of transporting the oil sample to be processed in a single direction.

[0051] In this embodiment, the gas collecting tank 40 is used to store the gas discharged from the first oil chamber 10. The first control valve 101, the third control valve 103, the fourth control valve 104, the fifth control valve 105 and the sixth control valve 106 are all gas-liquid dual-purpose solenoid three-way valves, and the second control valve 102 is a gas-liquid dual-purpose solenoid two-way valve.

[0052] It should be noted that, as Figure 2As shown, the solenoid valve is normally closed. The piping can be stainless steel. The first channel 1 of the first control valve 101 is connected to the gas collection tank 40 via a pipe. The third channel 3 of the first control valve 101 is connected to the exhaust port via a pipe. The second channel 2 of the first control valve 101 is connected to the top of the first oil chamber 10 via a pipe.

The other end of the second control valve 102 is connected to the first channel 1 of the third control valve 103, the first channel 1 of the fourth control valve 104, and the third channel 3 of the sixth control valve 106 via pipes. The third channel 3 of the third control valve 103 is connected to the bottom of the first oil chamber 10 via a pipe. The second channel 2 of the third control valve 103 is connected to the second channel of the second oil chamber 20 via a pipe. The third channel 3 of the fourth control valve 104 is connected to the first channel of the second oil chamber 20 via a pipe. The second channel 2 of the fourth control valve 104 is connected to the third channel 3 of the fifth control valve 105 via a pipe. The second channel 2 of the fifth control valve 105 is connected to the drive element 30 via a pipe. The first channel 1 of the sixth control valve 106 is connected to the drive element 30 via a pipe, and the second channel 2 of the sixth control valve 106 is connected to the oil outlet via a pipe. This dual-chamber vacuum spray oil degassing device uses a single drive element as the power structure to move the oil surface in the first oil chamber, creating vacuum conditions for the oil sample to be degassed, eliminating the need for a vacuum pump and reducing the cost of the equipment. The use of a two-chamber structure (first and second oil chambers) prevents newly injected oil samples from mixing with already degassed oil samples during the liquid surface collection stage, thus avoiding any impact on the degassing results.

[0053] like Figure 2 As shown, in one embodiment of this application, a temperature detection element 201 for detecting the oil temperature in the oil chamber is provided at the bottom of both the first oil chamber 10 and the second oil chamber 20; a heating element 202 for heating the oil in the oil chamber is provided on both sides of the first oil chamber 10 and the second oil chamber 20; a first liquid level detection element 203 for detecting whether the oil level in the oil chamber has reached the liquid level is provided above the first oil chamber 10, and a second liquid level detection element 204 for detecting whether the oil level in the oil chamber has reached the liquid level is provided below the first oil chamber 10; a pressure detection element 205 for detecting the internal pressure of the oil chamber is provided on the first oil chamber 10; and a spray element 50 for atomizing the oil in the oil chamber is provided inside the first oil chamber 10, and the spray element 50 is connected to a pipe having a second control valve 102.

[0054] It should be noted that the temperature detection element 201 can be a temperature sensor. The heating element 202 can bring the oil temperature in the first oil chamber 10 and the second oil chamber 20 to a set value. The first liquid level detection element 203 and the second liquid level detection element 204 can both be liquid level sensors, used to determine whether the oil volume in the degassing chamber and the oil chamber has reached the specified liquid level. The pressure detection element 205 can be a pressure sensor. The spray element 50 can be a sprayer. The spray element 50 can atomize the oil in the degassing chamber of the first oil chamber 10. In this embodiment, threaded holes for installing the first liquid level detection element 203 and the second liquid level detection element 204 are provided at both the upper and lower positions on one side of the first oil chamber 10. The first liquid level detection element 203 and the second liquid level detection element 204 are installed on the threaded holes of the first oil chamber 10 by thread fixing. The heating element 202 can be a heating resistor or other heatable electrical device. Threaded holes are provided at the bottom of the oil chamber in the first oil chamber 10 and at the bottom of the second oil chamber 20. The temperature sensing element 201 is fixedly installed on the first oil chamber 10 and the second oil chamber 20 by threaded connection. The pressure sensing element 205 is installed above the first oil chamber 10 by threaded connection and is on the same side as the temperature sensing element 201.

[0055] like Figure 2 As shown, in one embodiment of this application, a filter element 60 is provided at the top of the first oil chamber 10, and the filter element 60 is connected to the second channel 2 of the first control valve 102 through a pipe.

[0056] It should be noted that the filter element 60 can be a filter. In this embodiment, the top of the first oil chamber 10 is provided with an opening for installing the filter element 60, which is used to transfer the gas in the degassing chamber of the first oil chamber 10.

[0057] like Figure 1 As shown, the dual-chamber vacuum spray oil degassing method includes the following steps:

[0058] S1. Control the oil supply channel to open, and supply oil to the first oil chamber and the second oil chamber at a low speed until the oil level reaches the first position of the first oil chamber, and obtain the first feedback signal.

[0059] It should be noted that in step S1, the oil supply channel is opened, and oil is injected into the first and second oil chambers of the dual-chamber vacuum spray oil degassing device at a low speed through the driving element. When the oil level in the first oil chamber rises to the first position, the first and second oil chambers are filled with oil, and a first feedback signal is obtained. In this embodiment, the low speed can be 3ml / s to 5ml / s.

[0060] In this embodiment of the application, a first liquid level detection element is provided above the first oil cavity, and a second liquid level detection element is provided below the first oil cavity. The first position of the first oil cavity is the position of the first liquid level detection element, and the second position of the first oil cavity is the position of the second liquid level detection element.

[0061] It should be noted that the first liquid level detection element receives the first feedback signal.

[0062] S2. Based on the first feedback signal, control the oil supply channel to close and control the gas mixing channel to open. In the first time, use high speed to control the oil and gas in the first oil chamber and the second oil chamber to mix to obtain an oil-gas mixture liquid. Control the gas mixing channel to close and open the oil discharge channel, and use high speed to discharge the oil-gas mixture liquid in the first oil chamber and the second oil chamber to obtain a negative pressure signal.

[0063] It should be noted that in step S2, based on the first feedback signal, the oil supply channel is closed and the air-mixing channel is opened, increasing the operating speed of the drive element from low to high, and initiating the mixing of oil and gas in the first and second oil chambers. The oil in the first oil chamber, after circulating through the drive element and spray element for a first time, can integrate the gas in the first oil chamber into the oil. In this embodiment, the high speed can be 15ml / s to 18ml / s. The first time can be 3min to 5min.

[0064] In this embodiment, after the oil and gas mix in the first oil chamber, the mixing channel is closed and the oil discharge channel is opened to continue to discharge the oil-gas mixture in the first and second oil chambers through the oil outlet of the dual-chamber vacuum spray degassing device at high speed. At this time, the first oil chamber is under negative pressure, and a negative pressure signal is obtained.

[0065] S3. Based on the negative pressure signal, control the oil drain channel to close and open the oil supply channel, and supply oil to the first oil chamber and the second oil chamber at high speed until the oil temperature reaches the set temperature value and the oil level reaches the second position of the first oil chamber, thereby obtaining the second feedback signal.

[0066] It should be noted that in step S3, the oil drain channel is closed and the oil supply channel is reopened based on the negative pressure signal. The drive element rotates at high speed to inject oil into the first and second oil chambers. The heating element controls the oil temperature in the first and second oil chambers to the set temperature value. Once the oil level in the degassing chamber reaches the position of the second level detection element, the oil volume in the first oil chamber reaches the set value, and the second level detection element sends a second feedback signal. In this embodiment, the set temperature value can be 50 degrees Celsius.

[0067] S4. Based on the second feedback signal, control the oil supply channel to close and open the circulation degassing channel. In the second time period, use high speed to separate the oil and gas in the first oil chamber. After waiting for the third time period, obtain the gas to be discharged and the third feedback signal.

[0068] It should be noted that in step S4, based on the second feedback signal, the drive element continues to operate at high speed, initiating the circulation degassing stage within the first oil chamber. After circulating through the drive element and atomizing element for a second time, the oil in the first oil chamber separates the gas, which concentrates in the upper layer of the first oil chamber. After the circulation degassing is completed, the drive element is turned off, and the oil in the first oil chamber is allowed to stand still for a third time before the gas is fully released. In this embodiment, the second time can be 10 minutes, and the third time can be 5 minutes.

[0069] S5. Based on the third feedback signal, control the closed circulation degassing channel and open the gas collection channel, and use low speed to discharge the gas to be discharged in the first oil chamber to the gas collection tank until the oil level in the first oil chamber reaches its first position, so as to complete the oil degassing of the first oil chamber and the second oil chamber.

[0070] It should be noted that in step S5, the gas collecting channel is opened according to the third feedback signal, while the oil supply channel, gas mixing channel, oil discharge channel, and circulating degassing channel are all closed. The drive element is controlled to operate at low speed, transferring the oil in the second oil chamber to the first oil chamber. As the oil level in the first oil chamber rises, the gas removed from the oil above the first oil chamber will enter the gas collecting tank. When the liquid level reaches the first position, the first liquid level detection element sends a fourth feedback signal. Based on the fourth feedback signal, the drive element is controlled to stop, completing the degassing of the oil in the first and second oil chambers.

[0071] This application provides a dual-chamber vacuum spray oil degassing method, which includes controlling the oil supply channel to open, supplying oil to the first and second oil chambers at a low speed until the oil level reaches a first position in the first oil chamber, and obtaining a first feedback signal; based on the first feedback signal, controlling the oil supply channel to close and controlling the gas mixing channel to open, mixing the oil and gas in the first and second oil chambers at a high speed within a first time period to obtain an oil-gas mixture liquid; controlling the gas mixing channel to close and opening the oil discharge channel, and discharging the oil-gas mixture liquid in the first and second oil chambers at a high speed, obtaining a negative pressure signal; based on the negative pressure signal, controlling the oil discharge channel to close and opening the oil supply channel to open the oil discharge channel. The oil channel supplies oil to the first and second oil chambers at high speed until the oil temperature reaches the set value and the oil level reaches the second position in the first oil chamber, thus obtaining a second feedback signal. Based on the second feedback signal, the oil supply channel is closed and the circulation degassing channel is opened. During the second time period, the oil and gas in the first oil chamber are separated at high speed. After waiting for a third time period, the gas to be discharged and the third feedback signal are obtained. Based on the third feedback signal, the circulation degassing channel is closed and the gas collection channel is opened. The gas to be discharged in the first oil chamber is discharged into the gas collection tank at low speed until the oil level in the first oil chamber reaches its first position, thus completing the oil degassing of the first and second oil chambers. This dual-chamber vacuum spray oil degassing method controls the opening and closing of the oil supply channel, gas mixing channel, oil discharge channel, circulating degassing channel, and gas collection channel. Combined with the amount of oil to be degassed, time, temperature, and speed of the driving element, and employing a two-chamber structure of a first oil chamber and a second oil chamber, it can prevent newly injected oil samples from mixing with already degassed oil samples during the stage of pushing the liquid surface to collect gas. This allows the degassing oil to complete the degassing process quickly and efficiently, solving the technical problem that the existing control method of oil-immersed transformer degassing device cannot remove the mixing of newly injected oil samples, which affects the degassing results.

[0078] It should be noted that by controlling the opening or closing of each channel of the first, second, third, fourth, fifth, and sixth control valves of the dual-chamber vacuum spray oil degassing device, the opening and closing of the oil supply channel, gas mixing channel, oil discharge channel, circulating degassing channel, and gas collection channel can be achieved, facilitating the execution of the dual-chamber vacuum spray oil degassing method.
