[0002] In the power system, there are a large number of oil-less equipment or oil-less components, such as capacitor voltage transformers, high-voltage bushings of transformers, etc. As core components in the power network, the robustness and reliability of their operation are crucial to maintaining the safety and stability of the entire power grid. During the continuous operation of these equipment or components, they will be potentially affected by a variety of internal and external factors, such as electrical failures, natural aging of insulation materials, etc., which may induce internal failures. In order to effectively identify and prevent these potential failure risks in advance, it is particularly important to monitor the gas dissolved in the oil in the equipment, especially the close monitoring of acetylene gas, which is indispensable.

[0003] Traditional methods of monitoring dissolved gas in oil mainly rely on oil chromatography technology, which accurately analyzes the specific types and concentrations of gas in oil to determine whether there are abnormalities or faults inside the equipment. However, this technology has some limitations for acetylene measurement in low-oil equipment.

[0004] First, the oil chromatography online monitoring devices currently on the market are often large in size and have complicated and cumbersome installation processes, which makes them more suitable for large oil-filled equipment such as transformers, and difficult to apply to low-oil equipment or low-oil components; secondly, due to the limited oil volume of low-oil equipment, it is difficult to meet the multiple oil extraction requirements required by traditional dissolved gas measurement methods, which undoubtedly increases the difficulty of monitoring; thirdly, the oil extraction ports of low-oil equipment such as casings are usually set at high places, and their wiring layouts often cannot meet the safety distance requirements, which brings additional risks to monitoring work.

[0026] like Figure 1 As shown, the present invention proposes an acetylene intervention measurement system for low-oil equipment based on surface sensitive materials, including a micro acetylene sensor unit directly connected to an oil intake port, a plug-in sensor auxiliary drive unit and an integrated data system; wherein the micro acetylene sensor unit directly connected to the oil intake port is locked and connected to the oil intake port of the measured equipment through a conversion tooling that matches the oil intake port of the low-oil equipment; the micro acetylene sensor unit directly connected to the oil intake port and the plug-in sensor auxiliary drive unit are sealed and connected by plugging to form a measurement system body, and the plug-in sensor auxiliary drive unit is communicatively connected to the integrated data system.

[0027] The oil inlet direct-connected micro acetylene sensor unit is a metal shell packaging structure, and the oil inlet direct-connected micro acetylene sensor unit is connected to the oil inlet of the low-oil equipment to maintain equipotential connection. The oil inlet direct-connected micro acetylene sensor unit includes three parts: a self-locking three-way low-oil equipment interface tooling 1, an oil circuit drive module and an acetylene detection unit.

[0028] The self-locking three-way low-oil equipment interface tooling 1 includes a three-way oil circuit. The first oil circuit 2 is connected to the oil intake port of the low-oil equipment and remains in a normally open state. If possible, it should be a self-locking structure for easy disassembly; the second oil circuit 3 is connected to the oil circuit drive module and leads to the acetylene detection unit; the third oil circuit 4 is an oil intake port with a self-locking function, which can extend the original low-oil equipment oil intake port to the oil intake port of the third oil circuit 4, and oil can be taken through supporting equipment. When not taking oil, the oil intake port of the third oil circuit 4 is closed and kept in a sealed state; when taking oil, a special interface can be used to open the oil intake port by plugging in to make the oil circuit unobstructed.

[0029] In some embodiments, the first oil circuit 2 is an oil extraction port with a self-locking function, which is convenient for disassembly.

[0030] The oil circuit driving module includes a bidirectional capillary oil circuit 5, a micro peristaltic pump 7 and a micro oil chamber 6, ensuring that the oil circuit flows in and out of the micro oil chamber 6 slowly and orderly under the operating conditions, so as to ensure that the transformer oil to be measured in the measuring system is in a slowly updated state. The micro oil chamber 6 is connected to the second oil circuit 3 through the bidirectional capillary oil circuit 5, and the micro peristaltic pump 7 is arranged between the bidirectional capillary oil circuits 5. During the test, the oil sample to be measured is driven by the micro peristaltic pump 7 to flow into the micro oil chamber 6 through the inlet oil circuit of the bidirectional capillary oil circuit 5, and the residual oil in the micro oil chamber 6 is driven by the micro peristaltic pump 7 to flow out from the outlet oil circuit of the bidirectional capillary oil circuit 5, and is mixed with the oil of the oil-poor equipment body through the first oil circuit 2 and the second oil circuit 3.

The material of the acetylene gas sensitive sensor chip can be selected from tin dioxide, zinc oxide, tungsten trioxide, etc. At the same time, the semiconductor acetylene gas sensitive sensor chip is reduced to nanometer size to increase the specific surface area and enhance the detection limit. Since there are various types of semiconductor acetylene gas sensitive sensor chips with different structures, different materials and different doping in the current market, in order to enhance the applicability of the measurement system of the present invention, the modular surface sensitive material acetylene sensor 9 is set to a dynamic sealing plug-in structure so as to replace different acetylene gas sensitive sensor chips.

The plug-in sensor auxiliary drive unit is plugged and locked with the oil extraction port direct-connected micro acetylene sensor unit through a special aviation plug, and the circuit connection is completed. At the same time, the plug-in structure of the metal shell ensures reliable equipotential connection. The sensor drive module 11 is used to drive the modular surface sensitive material acetylene sensor 9 to work, and convert the analog signal collected by the modular surface sensitive material acetylene sensor 9 into data; it also includes a self-test module, which can monitor the working status of the modular surface sensitive material acetylene sensor 9 and the sensor drive module 11 in real time. The micro power supply module 13 is used to drive the micro vacuum pump 10 and the micro peristaltic pump 7 to work. The micro photovoltaic energy acquisition module 14 includes a photovoltaic panel 15 and an energy storage module. The photovoltaic panel 15 is integrated with the shell of the plug-in sensor auxiliary drive unit, that is, a ring-shaped coating; at the same time, the energy storage module is used to store the electric energy collected by the photovoltaic panel 15, which can ensure stable power supply. The wireless transmission module 12 adopts the 5G mode. The measuring system of the present invention does not need to be connected to any external signal line and can be installed in a strong field area.

[0034] The integrated data system can receive the sensor data collected by the sensor driving module 11 through the wireless transmission module 12 and perform data post-processing. The integrated data system has a preset data processing module, which can perform post-processing analysis on the collected data to obtain the concentration of dissolved acetylene in the oil. In addition, the integrated data system has a built-in analysis module for statistical analysis of changes in acetylene concentration, generating judgment results to assist technical personnel in analysis, and leaving a dedicated digital interface with the substation background. The integrated data system can be reused. The entire station is configured with one set to simultaneously collect monitoring data from multiple low-oil equipment in the station. The dissolved acetylene concentration data and analysis results in the oil can be transmitted to the cloud through the integrated data system, and technical personnel can achieve remote data access and real-time analysis through mobile applications.

The sensor driving module 11 of the plug-in sensor auxiliary driving module collects and processes the analog signal of the modular surface sensitive material acetylene sensor 9, and sends the data to the comprehensive data system in 5G mode through the wireless transmission module 12; the comprehensive data system receives the data and processes and analyzes it to obtain the concentration of dissolved acetylene in the oil. This measurement system can monitor the acetylene content of low-oil equipment in real time, perform statistical analysis on the change of acetylene concentration, and generate judgment results to assist technical personnel in analysis. This measurement system realizes remote data access, real-time analysis and result warning, thereby completing real-time online monitoring of acetylene concentration in oil of low-oil equipment.
