[0028] The following describes an oil monitoring device for a steam turbine according to an embodiment of the present utility model with reference to the accompanying drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described with reference to the accompanying drawings are exemplary and should not be construed as limiting the present utility model.

[0029] Figure 1 This is a schematic structural diagram of the oil monitoring device for a steam turbine according to an embodiment of the present utility model.

[0030] As Figure 1 shown, the oil monitoring device 10 for a steam turbine includes: a box body, the box body includes a first cavity 11 and a second cavity 12, an oil outlet 4, an oil inlet 5 and a first cable port are provided on the first cavity 11, and a second cable port 3 is provided on the second cavity 12; an oil circuit unit, the oil circuit unit is arranged in the first cavity 11 and includes an oil monitoring module 100 and a detection pipe section, the oil monitoring module 100 is arranged on the detection pipe section, and the detection pipe section is connected to the oil circuit of the steam turbine through the oil inlet 5 and the oil outlet 4; an electrical unit, the electrical unit is arranged in the second cavity 12 and includes a controller module 107, the controller module 107 is connected to an external cable through the second cable port 3 and is connected to the oil monitoring module 100 through the first cable port.

[0031] Specifically, the box body is provided to include a first cavity 11 and a second cavity 12, the oil circuit unit is arranged in the first cavity 11, and the electrical unit is arranged in the second cavity 12. Thus, by arranging the oil circuit unit and the electrical unit in two different cavities, the oil circuit unit and the electrical unit are independent of each other. Even if a fault such as oil leakage occurs in the oil circuit unit, it will not affect the electrical unit, thereby improving the safety of the oil monitoring device 10 for a steam turbine.

[0032] The oil circuit unit is provided to include an oil monitoring module 100, the oil monitoring module 100 is arranged on the detection pipeline, and the detection pipeline is connected to the oil circuit of the steam turbine, so that the oil in the steam turbine can flow in the detection pipeline. Furthermore, the oil monitoring module 100 arranged on the detection pipeline can monitor the oil in the detection pipeline, such as monitoring the moisture, water activity, viscosity, density, particle size, complex dielectric constant, acid value, oil temperature, etc. of the oil, thereby realizing the monitoring of the oil (such as lubricating oil, etc.) in the steam turbine, covering the most common problems such as system pollution, oil degradation, and excessive moisture, and overall characterizing the health state of the steam turbine.

[0033] The electrical pipeline is provided to include a controller module 107, the controller module 107 is connected to the oil monitoring module 100 through the first cable port, so as to control the oil monitoring module 100. It is also provided that the controller module 107 is connected to an external cable through the second cable port 3, so as to supply power to the controller module 107 through the external cable and make the controller module 107 work.

[0034] In the above implementation process, the oil circuit pipeline sucks in the oil through the oil inlet 5, and the oil then flows back to the steam turbine through the oil outlet 4, completing the oil monitoring and the oil circulation at the same time, without affecting the normal operation of the steam turbine.

[0035] As a specific embodiment, the second cavity 12 is arranged above the first cavity 11, and the oil outlet 4 is arranged above the oil inlet 5. The oil liquid monitoring device 10 for the steam turbine can be installed beside the steam turbine. On the side of the monitoring box, the second cable port 3, the oil outlet 4, and the oil inlet 5 are distributed from top to bottom. The second cable port 3 is used for connecting the cable. The cable includes a power supply line and a data line. The power supply line is used for power supply, and the data line is used for data transmission. The oil outlet 4 is the port where the bypass oil circuit flows out after passing through the box body, and the oil inlet 5 is the inlet where the bypass oil circuit enters the box body.

[0036] Both the above-mentioned oil circuit unit and the electrical unit are arranged in the box body, that is, a comprehensive monitoring box is set up. The box body of the comprehensive monitoring box is divided into two parts. One part is used as the first cavity to set the oil circuit unit, and the other part is used as the second cavity to set the electrical unit. Thus, it can be realized that by only moving the comprehensive monitoring box, the oil liquid monitoring device 10 for the steam turbine can be moved, which improves the portability and usability of the oil liquid monitoring device 10 for the steam turbine.

[0037] Moreover, the lower part of the two cavities divided in the box body is set as the first cavity, and the upper part is set as the second cavity. In this way, even if the oil circuit unit has a fault such as oil leakage, since the oil circuit unit is located below in the box body, the leaked oil will flow to the bottom of the box body, further avoiding the influence on the electrical unit and improving the safety of the above-mentioned oil liquid monitoring device 10 for the steam turbine.

[0038] Thus, the oil liquid monitoring device 10 for the steam turbine is set to include: a box body, the box body includes a first cavity 11 and a second cavity 12. The first cavity 11 is provided with an oil outlet 4, an oil inlet 5, and a first cable port. The second cavity 12 is provided with a second cable port 3; an oil circuit unit, the oil circuit unit is arranged in the first cavity 11 and includes an oil liquid monitoring module 100 and a detection pipe section. The oil liquid monitoring module 100 is arranged on the detection pipe section. The detection pipe section is connected to the oil circuit of the steam turbine through the oil inlet 5 and the oil outlet 4; an electrical unit, the electrical unit is arranged in the second cavity 12 and includes a controller module 107. The controller module 107 is connected to the external cable through the second cable port 3 and is connected to the oil liquid monitoring module 100 through the first cable port, thereby monitoring the oil in the steam turbine, realizing real-time monitoring of the conditions such as the lubrication state of the steam turbine, taking corresponding measures in time, and providing guarantee for the long-term stable operation of the equipment. After actual measurement, the lubricating oil of the steam turbine deteriorates due to steam leakage and water ingress in about three months, and about 2400L of lubricating oil is replaced each time. After installing the oil liquid monitoring device 10 for the steam turbine on this steam turbine, the system alarms the rise of moisture in time within one week after installation. After timely treatment, abnormal oil product loss and equipment wear caused by long-term poor lubrication are avoided.

[0039] In an embodiment of the present utility model, refer to Figure 2 , the electrical unit further includes: an electromagnetic interference prevention module 106. The electromagnetic interference prevention module 106 is disposed within the electrical unit to achieve electrical isolation and prevent signal transmission problems caused by electromagnetic signal interference. Especially in the case where the electrical part inside the box is complex and prone to electromagnetic interference, signal transmission failure can be more effectively avoided.

[0040] In an embodiment of the present utility model, the electromagnetic interference prevention module 106 is connected to the line where the controller module 107 is connected to the external cable or the oil fluid monitoring module 100. That is to say, the electromagnetic interference prevention module 106 is arranged to be connected to the controller module 107, so that the controller module 107 can control the electromagnetic interference prevention module 106 and improve the working performance of the electromagnetic interference prevention module 106. Moreover, it also supports supplying power to the controller module 107 and the electromagnetic interference prevention module 106 through one cable at the same time, improving the space utilization rate and integration degree of the electrical unit. Figure 3 This is a specific embodiment where the electromagnetic interference prevention module 106 is connected to the line where the controller module 107 is connected to the external cable.

[0041] In an embodiment of the present utility model, refer to Figure 4 , the oil fluid monitoring module 100 includes a particle size detection sub-module 102, an oil quality detection sub-module 103, a moisture detection sub-module 104, and a flow rate monitoring sub-module 105. The particle size detection sub-module 102, the oil quality detection sub-module 103, the moisture detection sub-module 104, and the flow rate monitoring sub-module 105 are respectively connected to the controller module 107 through the first cable port.

[0042] Thus, through multiple detection sub-modules, multiple parameters of the oil in the steam turbine can be monitored, thereby overall characterizing the health status of the steam turbine. Moreover, since no filter is provided and the particulate matter in the oil will not be filtered, the particle size detection sub-module 102 can achieve accurate detection, thus truly reflecting the particulate matter condition in the oil product.

[0043] In an embodiment of the present utility model, refer to Figure 5 , the oil circuit unit further includes a flow rate adjustment module 101. The flow rate adjustment module 101 is disposed on the detection pipe section and is connected to the controller module 107 through the first cable port. Thus, through the flow rate adjustment module 101, the flow rate of the oil flowing through the oil fluid monitoring module 100 is adjusted. The above-mentioned flow rate adjustment module 101 may include a flow rate regulating valve. The lubricating oil passes through the oil inlet 5, successively passes through the flow rate regulating valve 101, the particle size detection sub-module 102, the oil quality detection sub-module 103, the moisture detection sub-module 104, the flow rate monitoring sub-module 105, and finally returns to the oil circuit through the oil outlet 4.

[0044] In an embodiment of the present utility model, refer toFigure 6 The electrical unit further includes: a power supply module 109, which is respectively connected to the controller module 107, the electromagnetic interference prevention module 106, and the oil fluid monitoring module 100 to supply power to the controller module 107, the electromagnetic interference prevention module 106, and the oil fluid monitoring module 100.

[0045] In an embodiment of the present utility model, refer to Figure 7 , the power supply module 109 is also connected to an external power supply through the second cable port 3. At this time, the external power supply can be set to supply power to the power supply module 109, and then the power supply module 109 supplies power to the controller module 107, the electromagnetic interference prevention module 106, and the oil fluid monitoring module 100.

[0046] In an embodiment of the present utility model, refer to Figure 8 , the electrical unit further includes: an air circuit breaker 108, and the power supply module 109 is connected to the external power supply through the air circuit breaker 108. When the current provided by the external power supply is too large, the air circuit breaker 108 will disconnect to protect the electrical module and prevent the production power grid from becoming unstable.

[0047] In an embodiment of the present utility model, refer to Figure 9 , the electrical unit further includes a gateway 110, and the gateway 110 is connected to the controller module 107 through a data line.

[0048] Specifically, it is set that the gateway 110 is connected to the controller module 107 through a data line. After the controller module 107 receives the data sent by the oil fluid monitoring module 100, the controller module 107 sends the received data to the gateway 110, so that the gateway 110 performs edge computing based on the data and sends the calculation result to the controller module 107, and then the controller module 107 performs subsequent processing. For example, the flow rate monitoring sub-module 105 sends the monitored flow rate data to the controller module 107, and then the controller module 107 sends it to the gateway 110. After the gateway 110 receives the flow rate data, it performs edge computing to obtain the setting parameters of the particle size detection sub-module 102, and sends the setting parameters to the controller module 107. The controller module 107 sets the particle size detection sub-module 102 according to the setting parameters.

[0049] Among them, it can be set that the line connecting the gateway 110 and the controller module 107 is different from other parts. For example, it can be set that the gateway 110 and the controller module 107 are connected through a network cable, while other parts are connected through the above-mentioned cable.

[0050] Moreover, it can also be set that after the gateway 110 receives the data sent by the oil fluid monitoring module 100 and the flow rate adjustment module 101, it wirelessly sends the data to an external device for calculation through the external device.

[0051] It is also possible to set the controller module 107 to send the data received from the oil fluid monitoring module 100 and the flow rate adjustment module 101 to an external device through a cable for calculation by the external device.

[0052] Thus, it is possible to calculate the data collected by the oil fluid monitoring module 100 and perform control based on the calculation results, thereby achieving more precise control. For example, common particle size sensors use the light passing method principle to monitor the number of particles in different particle size ranges in the fluid passing through the sensor path within a certain time, which is closely related to the flow rate. Therefore, by setting the monitoring of the flow rate in the oil circuit and controlling the particle size detection sub-module 102 according to the monitoring results, more precise control of the particle size detection sub-module 102 is achieved. Moreover, it is also possible to set the gateway 110 to perform edge computing, thereby achieving fast response and further achieving more precise control.
