Description

Technical Field

[0001] This utility model relates to the field of oil monitoring technology, specifically to an online oil monitoring device for a synchronous condenser with leakage monitoring function. Background Technology

[0002] Traditional synchronous condenser oil monitoring typically uses single-parameter sensors, requiring the separate installation of sensors for viscosity, trace moisture, temperature, dielectric constant, metal abrasive particles, and contamination levels to comprehensively integrate various aspects of oil data. This provides a data foundation for analyzing the operational health of large machinery. The oil monitoring device is installed on a beam next to the oil tank and is connected to the monitoring box and the oil tank's oil circuit via an oil pipe (stainless steel pipe or high-pressure hose). The unfiltered oil enters the monitoring box for testing, and after testing, it returns to the oil tank's return oil line, forming an oil circuit for oil monitoring.

[0003] However, since the aforementioned single-parameter sensors work independently, each sensor only captures changes in a single physical or chemical indicator. When a leak occurs in the pipeline, it is usually impossible to accurately identify the leak, which limits the online oil monitoring device. Furthermore, if the leaked oil comes into contact with high-temperature components or electrical systems, it may cause combustion, posing a certain safety hazard. Utility Model Content

[0035] Please see Figure 1-8This utility model provides a technical solution: an online oil monitoring device for a synchronous condenser with leakage detection function, including a housing 1 and an oil tank 2. The housing 1 is installed on one side of the oil tank 2 via a quick-release mechanism 3. An orifice-shaped pipe 4 and a control system are installed inside the housing 1. An oil intake pipe 5 and an oil return pipe 6 are connected to the oil tank 2. One end of the orifice-shaped pipe 4 is connected to the oil intake pipe 5 via a diaphragm pump 7. The end of the orifice-shaped pipe 4 opposite to the diaphragm pump 7 is connected to the oil return pipe 6. Sensor groups 8 for logarithmic detection of synchronous condenser oil are installed on both sides of the orifice-shaped pipe 4. The oil intake pipe 5, the orifice-shaped pipe 4, and the oil return pipe 6 form a detection flow channel. Oil in tank 2 is transferred to pipe 4 via oil intake line 5 and diaphragm pump 7. The oil path splits into two branches in pipe 4, each monitored by two sets of sensors 8. Finally, the oil returns to tank 2 via return line 6, forming a closed-loop detection channel. This ensures continuous and stable detection of the oil. Through the cooperation of the control system and the two sets of sensors 8, oil in tank 2 is transferred to pipe 4 via oil intake line 5. Pipe 4 splits the oil path into two branches, and the two sets of sensors 8 monitor the parameters of both branches. The control system receives and processes the parameters, taking the average value as the monitoring value. This reduces the error that may occur with a single sensor and improves the accuracy of oil path monitoring.

[0036] The oil intake line 5, the orifice-shaped line 4, and the return line 6 form a detection channel. A leak detection component that detects pressure surges is installed on the detection channel. The control system is electrically connected to the leak detection component and the sensor group 8. During the monitoring of the phase shifter oil, while the sensor group 8 monitors the phase shifter oil parameters, the leak detection component can also accurately identify whether there is a leak in the channel by detecting pressure surges in the detection channel, thereby improving the safety of online oil monitoring.

[0037] The leak detection assembly includes a first pressure sensor 9 installed at the outlet of the diaphragm pump 7, a third pressure sensor 10 installed at the inlet of the return oil line 6, a fourth pressure sensor 11 installed inside the oil tank 2, and two sets of second pressure sensors 12 respectively installed at the nozzle sensor group 8. The first pressure sensor 9, second pressure sensor 12, third pressure sensor 10, and fourth pressure sensor 11 are all electrically connected to the control system. The first pressure sensor 9 monitors the pressure at the outlet of the diaphragm pump 7, the third pressure sensor 10 monitors the pressure at the inlet of the return oil line 6, the fourth pressure sensor 11 monitors the pressure inside the oil tank 2, and the two sets of second pressure sensors 12 respectively monitor the pressure at the nozzle sensor group 8. When a sudden pressure change occurs in the detection channel, it can accurately identify whether a leak has occurred in the channel, enabling real-time monitoring of pressure changes within the detection channel, timely detection of leaks, improved safety of online oil monitoring, and prevention of losses and safety hazards caused by oil leaks.

[0038] One end of the orifice-shaped pipe 4 is connected to the oil intake pipe 5 and is connected to the oil inlet pipe 13. The opposite side of the orifice-shaped pipe 4 is connected to the oil outlet pipe 14. Both the oil inlet pipe 13 and the oil outlet pipe 14 are fixed with connecting flanges. Both the oil intake pipe 5 and the return pipe 6 are fixed with mating flanges that connect to the connecting flanges. The connecting flanges and the mating flanges are connected by bolts, and a sealing ring is provided between the connecting flanges and the mating flanges. The connection method is simple and reliable, and is easy to install and disassemble. The sealing ring ensures the sealing of the connection and prevents oil leakage.

[0039] A one-way valve 15 is installed on the oil inlet pipe 13, and a regulating valve 16 is installed on the oil return pipe 6. The one-way valve 15 on the oil inlet pipe 13 ensures that the oil can only flow from the oil intake pipe 5 to the orifice pipe 4; the regulating valve 16 on the oil return pipe 6 can adjust the return oil flow rate, and the one-way valve 15 prevents the oil from flowing back, ensuring the normal flow direction of the oil in the detection channel; the regulating valve 16 can adjust the return oil flow rate according to actual needs, making the detection system more flexible and controllable.

[0040] The chassis 1 is internally fixed with a partition 17, which divides the chassis 1 into a detection chamber 18 and a control chamber 19. The orifice-shaped pipe 4 is located in the detection chamber 18, and the control system is installed in the control chamber 19. Both the detection chamber 18 and the control chamber 19 have a door 20 on one side. The control chamber 19 has multiple sets of ventilation holes 21 on its opposite side walls. The partitioned design of the detection chamber 18 and the control chamber 19 separates the detection components and the control system, reduces mutual interference, and facilitates maintenance and management. The door 20 facilitates the inspection and maintenance of internal components. The ventilation holes 21 promote air circulation in the control chamber 19 and dissipate heat for the control system.

[0041] The control system includes a control motherboard 22 fixed in the control cavity 19. The control motherboard 22 is equipped with a controller and an audible and visual alarm. When the sensor group 8 and the leakage detection component detect an abnormality, the controller controls the audible and visual alarm to sound an alarm. The audible and visual alarm can promptly remind the staff that the detection system has an abnormality.

[0042] The control system also includes a lithium battery 23 for providing power to the controller. The lithium battery 23 is detachably installed in the control cavity 19 via a battery holder. The lithium battery 23 ensures the normal operation of the control system when there is no external power source, and the detachable design facilitates maintenance.

[0043] The control system also includes a wireless module 24, which is electrically connected to the controller. The wireless module 24 is located on one side of the control motherboard 22. The wireless module 24 enables remote data transmission, facilitating remote monitoring and management.

[0044] The sensor group 8 includes an abrasive sensor 81, a micro-water sensor 82, a wastewater sensor 83, and a multi-functional sensor 84. The sensing ends of the abrasive sensor 81, micro-water sensor 82, wastewater sensor 83, and multi-functional sensor 84 are all installed inside the orifice-shaped pipe 4. The two sensor groups 8 on the orifice-shaped pipe 4 are installed in the same order. Multiple sensors can simultaneously detect different parameters of the oil, providing a comprehensive understanding of the oil's state. The identical installation order ensures the consistency of the detection conditions of the two sensor groups 8, making the averaging operation more comparable and accurate.

[0045] The quick-release mechanism 3 includes a fixing block 31 fixed on one side of the chassis 1 opposite to the oil tank 2, and an L-shaped block 32 fixed to one side of the oil tank 2 by bolts. A plug rod 33 is threaded onto the fixing block 31. The horizontal end of the L-shaped block 32 has a insertion hole 34 for inserting the other end of the plug rod 33, and a locking bolt 35 is threaded onto one side of the insertion hole 34. Two sets of quick-release mechanisms 3 are provided, located on opposite sides of the chassis 1. One end of the plug rod 33 has an external thread on its outer wall. During installation, the threaded end of the insertion rod 33 is threaded onto the fixing block 31, and the other end of the insertion rod 33 is inserted into the insertion hole 34. Then, the locking bolt 35 is used to lock it in place to fix the insertion position of the insertion rod 33. When removing it, simply loosen the locking bolt 35 and pull the insertion rod 33 out of the insertion hole 34. With the quick-release mechanism 3, the chassis 1 can be quickly installed on one side of the oil tank 2 without the need for an additional mounting bracket, thus saving on the convenience of installing the chassis 1.

[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
