Description

Technical Field

[0001] This invention relates to the field of transformer fault early warning technology, and in particular to a method and apparatus for collecting transformer insulation oil fume particles. Background Technology

[0002] Transformers are core equipment in the power grid, and their operational reliability is of paramount importance. When faults such as localized overheating or discharge occur inside a transformer, the aging and decomposition of insulating oil and solid insulating materials are accelerated, producing a mixture containing characteristic gases and oil fume particles. These oil fume particles themselves originate from the oil, and their composition directly reflects the chemical reactions at the fault location.

[0003] Existing technologies, such as oil chromatography, primarily focus on the gaseous components dissolved in oil, lacking the ability for direct, in-situ analysis of the oil fume particles themselves. Smoke, as a crucial parameter for early fire detection, has optical properties that are a significant area of ​​current research. The particle size and distribution patterns of smoke particles are important factors influencing their optical properties, and the growth patterns and geometric characteristics of smoke particles form the basis for smoke particle size measurement research.

[0004] Currently, the collection and analysis of transformer fault products face the following technical challenges: 1. Sampling lag: Typically, the system needs to be shut down or manually extracted from the sampling valve and sent to the laboratory for analysis. This process is cumbersome, lacks timeliness, and fails to capture the transient and developmental processes of the fault. 2. Insufficient particle characteristic analysis: There is a lack of dedicated online devices for collecting and preliminarily analyzing the physical characteristics of oil fume particles, making it difficult to directly correlate the spatiotemporal information of the particles with the fault type.

[0005] Therefore, there is an urgent need for a device and method that can automatically and in real time collect oil fume particles from transformer oil under different aging conditions and analyze their spatiotemporal distribution characteristics, so as to achieve early warning and accurate location of internal transformer faults. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide a method and device for collecting particles of transformer insulating oil, which can collect particles of transformer insulating oil and realize early warning of internal faults of transformer; the structure is simple, easy to repair and maintain, and safe and reliable.

[0007] To address the aforementioned technical problems, this invention provides a method for collecting transformer insulating oil fume particles, comprising the following steps: placing the transformer insulating oil to be studied into a combustion chamber; inspecting a probe capable of horizontally entering and exiting the combustion chamber to confirm that the distance between the probe tip and the combustion chamber is at an initially predetermined distance, and installing a carbon support film in the stepped hole at the probe tip; performing multiple samplings by adjusting the probe according to a set number of cycles, including: collecting fume particles at the same height at different time points or at different heights at the same time point in the combustion chamber, and retrieving the samples collected on the probe; and resetting the components of the combustion chamber after confirming that the probe has returned to its initial position.

[0008] The steps of placing the transformer insulating oil to be studied into the combustion chamber include the following: adding the transformer insulating oil to be studied through the inlet at the bottom of the combustion chamber, and opening the gas-support door at the top of the combustion chamber at a certain angle for smoke exhaust.

[0009] The step of checking the probe that can horizontally enter and exit the combustion chamber and confirming that the distance between the tip of the probe and the combustion chamber is within the initially predetermined distance includes the following: confirming the position of the probe tip through the data displayed on the touch screen of the control component; calibrating the position data of the probe through the touch screen; and inputting the appropriate sampling time, sampling interval time, number of cycles, and operating speed of the probe on the touch screen of the control component.

[0010] The process of collecting smoke particles at the same height in the combustion chamber at different time points, or at the same time point at different heights, and retrieving the samples collected on the probe includes the following steps: Driven by a servo motor and a reducer, the robotic arm moves the probe towards the combustion chamber. The probe passes through the combustion chamber and reaches a predetermined position, exposing the carbon support film to the transformer insulating oil fumes. The hot smoke particles are adsorbed onto the cooler carbon support film, completing the collection of smoke particles at the first time point. After reaching the set sampling time, the probe exits the combustion chamber and returns to its original position. After the sampling interval, the process of collecting smoke particles is repeated to collect smoke particles at the second time point. The sampling at different time points is completed according to the set number of cycles.

[0011] The steps after completing the first time point smoke particle collection include: removing the carbon support film cover plate at the probe tip, using tweezers to remove the carbon support film from the step hole; picking up a new carbon support film and placing it back into the step hole, and then putting the carbon support film cover plate back into the step hole.

[0012] To address the aforementioned technical problems, this invention also discloses a device for collecting transformer insulating oil fume particles, comprising: a combustion chamber for holding the transformer insulating oil to be studied; a probe capable of horizontally entering and exiting the combustion chamber, the probe having a stepped hole at its front end for placing a carbon support film, and a carbon support film cover plate at the front end of the probe to prevent the carbon support film from falling out of the stepped hole; a control component for confirming whether the distance between the tip of the probe and the combustion chamber is within an initial predetermined distance; and a robotic arm, servo motor, and reducer for collecting fume particles at the same height at different time points or fume particles at different heights at the same time point in the combustion chamber.

[0013] The system consists of multiple probes; a robotic arm moves the probes horizontally in and out of the combustion chamber; and a servo motor and a reducer provide power to the probes.

[0014] The control components include a touch screen for adjusting the probe's initial position, sampling time, sampling interval, number of cycles, and running speed.

[0015] The combustion chamber is equipped with an air-supported door at the top that can be opened at a certain angle for exhaust; an inlet for adding the transformer insulating oil to be studied at the bottom; and a perforated structure on the side frame of the combustion chamber for allowing a probe to enter and exit the combustion chamber horizontally.

[0016] The combustion chamber is a frame structure made of multiple aluminum profiles that are interlocked. Stainless steel plates and explosion-proof glass are installed on opposite sides of the combustion chamber, allowing observation of the combustion of transformer insulating oil under different aging conditions through the explosion-proof glass. The bottom of the combustion chamber is equipped with multiple casters.

[0017] The method and apparatus for collecting transformer insulating oil fume particles according to the present invention have the following beneficial effects: The method for collecting transformer insulating oil fume particles includes: placing the transformer insulating oil to be studied into the combustion chamber; inspecting a probe that can horizontally enter and exit the combustion chamber to confirm that the distance between the tip of the probe and the combustion chamber is at an initially predetermined distance; installing a carbon support film in the stepped hole at the tip of the probe; performing multiple samplings by adjusting the probe according to a set number of cycles, including: collecting smoke particles at the same height at different time points or smoke particles at different heights at the same time point in the combustion chamber; and retrieving the samples collected on the probe; determining that the probe has returned to its initial position and resetting the components of the combustion chamber. This method can collect smoke particles from transformer insulating oil in different aging states at different times and in different spaces, achieving early warning of internal transformer faults; the structure is simple, easy to repair and maintain, and safe and reliable.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] like Figures 1-4 The image shows an embodiment of the transformer insulation oil fume particle collection device of the present invention.

[0026] The transformer insulating oil fume particle collection device in this embodiment of the invention includes: a combustion chamber 1 for holding the transformer insulating oil to be studied; a probe 2 capable of horizontally entering and exiting the combustion chamber 1, the probe 2 having a stepped hole 21 at its front end for placing a carbon support film A, and a carbon support film cover plate at the front end of the probe 2 to prevent the carbon support film A from falling out of the stepped hole 21; a control component for confirming whether the distance between the tip of the probe 2 and the combustion chamber 1 is within an initial predetermined distance; and a robotic arm 3, a servo motor 5, and a reducer 4 for collecting fume particles at the same height at different time points or fume particles at different heights at the same time point in the combustion chamber 1.

[0027] The probe 2 is configured as multiple probes; the probe 2 is moved horizontally into and out of the combustion chamber 1 by the robotic arm 3; the probe 2 is powered by the servo motor 5 and the reducer 4.

[0028] In practice, the combustion chamber 1 is a frame structure made up of multiple aluminum profiles 1b that are overlapped with each other. Stainless steel plates and explosion-proof glass 13 are installed on opposite sides of the combustion chamber 1, and the combustion of transformer insulating oil under different aging conditions can be observed through the explosion-proof glass 13.

[0029] The side of the stainless steel plate mounted on the combustion chamber 1 has multiple square holes. In this embodiment, the square holes are evenly distributed upwards from a height of 0.3m above the bottom surface of the stainless steel plate. The purpose of the multiple square holes is twofold: firstly, to accommodate thermocouples; and secondly, to allow the probe 2 to enter the combustion chamber 1. In other words, the side frame surface of the combustion chamber 1 has a perforated structure for allowing the probe 2 to enter and exit the combustion chamber 1 horizontally.

[0030] Furthermore, the bottom of the combustion chamber 1 is equipped with an entry door for adding the transformer insulating oil to be studied. In this embodiment, the entry door is a small door 0.2m wide and 0.3m high, used to add the transformer insulating oil and ignite it; multiple casters 14 are installed at the bottom of the combustion chamber 1 to facilitate the movement of the entire device. By setting the casters 14, the transformer insulating oil fume particle collection device can be placed in any environment, such as toxic or harmful environments or low-pressure and low-oxygen environments, to collect transformer insulating oil fume particles under different conditions and in different spaces.

[0031] Furthermore, the carbon support film A is placed in the stepped hole 21 at the front end of the probe 2 for the collection and storage of transformer insulation oil fume particles; the carbon support film cover plate is used to fix the carbon support film A to prevent the carbon support film A from falling off due to vibration during the movement of the probe 2.

[0032] Preferably, the top of the combustion chamber 1 is also provided with an air-support door 11 that can be opened at a certain angle for exhausting smoke.

[0033] Furthermore, the robotic arm 3 is the main body of the entire mechanical device, used to fix the probe 2 and move it horizontally left and right to complete the action of entering and exiting the combustion chamber 1. The servo motor 5 and the reducer 4 are used to provide power to the probe 2; the probe 2 corresponds one-to-one with multiple square holes, is made of stainless steel, and each of the five probes is 0.5m long. The front end of the probe 2 is provided with a stepped hole 21.

[0034] During implementation, the initial distance between the tip of probe 2 and the square hole is 0.1m. After receiving the acquisition signal, probe 2 extends 0.4m into combustion chamber 1, that is, the length of the part entering combustion chamber 1 is 0.3m.

[0035] The stepped hole 21 on probe 2 is used to place carbon support film A, which is used for the collection and storage of transformer insulation oil fume particles.

[0036] Furthermore, the control component 6 includes a touch screen 60 for adjusting the initial position of the probe 2, sampling time, sampling interval time, number of cycles, and operating speed. In implementation, the control component 6 includes a housing, a control cabinet mounted on the housing, the touch screen 60 mounted on the control cabinet, and the control cabinet also includes inlet / outlet cables and a power supply button.

[0037] During implementation, open the control cabinet, power on the entire control system, check if the touch screen is lit, and check if the servo motor 5 and reducer 4 are in normal working condition; observe the data displayed on the touch screen 60 to confirm if the probe 2 is at the origin. If it is at the origin, proceed to the next step; if it is not at the origin, perform position calibration using the buttons on the touch screen 60; input the appropriate sampling time, sampling interval, number of cycles, and probe running speed on the touch screen 60 according to the aging state of the transformer insulating oil; after completing the system adjustment, place the carbon support film A into the stepped hole 21 at the front end of the probe 2 to complete the preparation work for the acquisition process.

[0038] In the specific implementation of the transformer insulating oil fume particle collection device in this embodiment of the invention, the transformer insulating oil is ignited, and the transformer insulating oil to be studied is added through the inlet at the bottom of the combustion chamber 1. The inlet is closed, and the brake button on the control cabinet is pressed at the same time. The robotic arm 3, driven by the servo motor 5 and the reducer 4, drives the probe 2 to start moving to the left. The probe 2 enters the combustion chamber 1 through the square hole in the stainless steel plate and reaches the predetermined position, exposing the carbon support film A to the transformer insulating oil fume. The hot fume particles are adsorbed onto the relatively cool carbon support film A, completing the collection of fume particles at the first time point.

[0039] After the set sampling time is reached, probe 2 automatically exits the combustion chamber and returns to its original position. At this time, the carbon support membrane cover is removed, and the carbon support membrane A in the step hole 21 is taken out with tweezers. The new carbon support membrane A is picked up and placed back into the step hole 21, and the carbon support membrane cover is put back into the step hole. After the sampling interval time is reached, probe 2 repeats the above steps to complete the collection of smoke particles at the second time point. According to the set number of cycles, sampling at different time points is completed.

[0040] When probe 2 collects transformer insulating oil fume particles at different heights at the same time, probe 2 enters combustion chamber 1 through the square hole in the stainless steel plate and reaches the predetermined position, exposing the carbon support film A to the transformer insulating oil fume. The hot fume particles are adsorbed onto the cooler carbon support film, completing the collection of fume particles. After the set sampling time is reached, probe 2 automatically exits combustion chamber 1 and returns to the original position; robotic arm 3 stops working.

[0041] In this way, by adjusting the time when probe 2 enters combustion chamber 1, the sampling time, the sampling interval time, and the number of cycles, the automatic collection of smoke particles from transformer insulating oil in different aging states at different times and in different spaces can be achieved, avoiding possible errors when manually holding tweezers for sampling, making the whole process safe and effective.

[0042] like Figure 5 The image shows an embodiment of the method for collecting transformer insulation oil fume particles according to the present invention.

[0043] To address the aforementioned technical problems, this invention also discloses a method for collecting transformer insulation oil fume particles, comprising the following steps: Step S10: Place the transformer insulating oil to be studied into the combustion chamber; Step S20: Inspect the probe that can enter and exit the combustion chamber horizontally, confirm that the distance between the tip of the probe and the combustion chamber is within the initial predetermined distance, and install a carbon support film in the stepped hole at the tip of the probe. Step S30: According to the set number of cycles, multiple samplings are completed by adjusting the probe, including: collecting smoke particles at different times at the same height in the combustion chamber or smoke particles at different heights at the same time point, and collecting the samples collected on the probe. Step S40: Determine that the probe has returned to its initial position and perform a reset operation on each component of the combustion chamber.

[0044] In specific implementation, step S10 includes the following steps: adding the transformer insulating oil to be studied through the inlet at the bottom of the combustion chamber, and opening the gas-support door at the top of the combustion chamber at a certain angle for smoke exhaust.

[0045] Step S20 includes the following steps: confirming the position of the probe tip by using the data displayed on the touch screen of the control component; calibrating the position data of the probe by using the touch screen; and inputting the appropriate sampling time, sampling interval time, number of cycles, and running speed of the probe on the touch screen of the control component.

[0046] Step S30 involves collecting smoke particles at the same height at different time points in the combustion chamber, or smoke particles at different heights at the same time point, and retrieving the samples collected on the probe. This includes the following steps: Driven by a servo motor and reducer, the robotic arm moves the probe towards the combustion chamber. The probe passes through the combustion chamber and reaches the predetermined position, exposing the carbon support film to the transformer insulating oil fumes. The hot smoke particles are adsorbed onto the cooler carbon support film, completing the collection of smoke particles at the first time point. After the set sampling time is reached, the probe exits the combustion chamber and returns to its original position. After the sampling interval is reached, the process of collecting smoke particles is repeated to collect smoke particles at the second time point. According to the set number of cycles, sampling at different time points is completed.

[0047] Step S30, after completing the first time point smoke particle collection step, includes: removing the carbon support film cover plate at the probe tip, removing the carbon support film from the step hole with tweezers; picking up a new carbon support film and placing it back into the step hole, and then covering the carbon support film cover plate back into the step hole.

[0048] It is understandable that if studying the morphological characteristics of smoke particles at different times at the same height, it is necessary to set the sampling time, sampling interval, and number of cycles through the control system based on the aging characteristics of transformer insulating oil. If studying the morphological characteristics of smoke particles at different heights at the same time, it is also necessary to set the sampling time through the control system based on the aging characteristics of transformer insulating oil, but it is not necessary to set the sampling interval and number of cycles.

[0049] In this embodiment, the method for collecting transformer insulating oil fume particles involves opening the airlock 11 upwards at a certain angle for smoke exhaust. A 10cm x 10cm oil pan is prepared, and the transformer insulating oil to be studied is added. The transformer insulating oil is ignited, and then added through the inlet at the bottom of the combustion chamber 1. The inlet is closed, and simultaneously the power button on the control cabinet is pressed to power on the entire control system. The touchscreen display 60 is checked for illumination, and the servo motor 5 and reducer 4 are checked for normal operating conditions. The data displayed on the touchscreen display 60 is observed to confirm whether the probe 2 is at the origin. If it is at the origin, the next step is performed; otherwise, the position is calibrated using the buttons on the touchscreen display 60.

[0050] Based on the aging state of the transformer insulating oil, input the appropriate sampling time, sampling interval, number of cycles, and probe 2 running speed on the touch display screen 60. Then, place the carbon support film A into the stepped hole 21 at the front end of probe 2 to complete the preparation work for the acquisition process.

[0051] Driven by the servo motor 5 and the reducer 4, the robotic arm 3 drives the probe 2 to move to the left. The probe 2 enters the combustion chamber 1 through the square hole in the stainless steel plate and reaches the predetermined position, exposing the carbon support film A to the transformer insulating oil smoke. The hot smoke particles are adsorbed onto the cooler carbon support film A, completing the collection of smoke particles at the first time point.

[0052] After the set sampling time is reached, probe 2 automatically exits the combustion chamber and returns to its original position. At this time, the carbon support membrane cover is removed, and the carbon support membrane A in the step hole 21 is taken out with tweezers. The new carbon support membrane A is picked up and placed back into the step hole 21, and the carbon support membrane cover is put back into the step hole. After the sampling interval time is reached, probe 2 repeats the above steps to complete the collection of smoke particles at the second time point. According to the set number of cycles, sampling at different time points is completed.

[0053] When probe 2 collects transformer insulating oil fume particles at different heights at the same time, probe 2 enters combustion chamber 1 through a square hole in a stainless steel plate and reaches a predetermined position, exposing the carbon support film A to the transformer insulating oil fume. The hot fume particles are adsorbed onto the cooler carbon support film A, completing the collection of fume particles. After the set sampling time is reached, probe 2 automatically exits combustion chamber 1. The user can confirm whether probe 2 has returned to its original position via the touch display screen 60. The robotic arm 3 stops working, closes the gas spring door 11, removes the oil pan, and restores the automated collection device to its initial state.

[0054] The method for collecting transformer insulating oil fume particles in this embodiment achieves automated collection of fume particles from transformer insulating oil in different aging states at different times and in different spaces by adjusting the time when the probe enters the combustion chamber, the sampling time, the sampling interval, and the number of cycles. This avoids errors that may occur when manually holding tweezers for sampling, making the whole process safe and effective.

[0055] The method and apparatus for collecting transformer insulating oil fume particles according to the present invention have the following beneficial effects: The method for collecting transformer insulating oil fume particles includes: placing the transformer insulating oil to be studied into the combustion chamber; inspecting a probe that can horizontally enter and exit the combustion chamber to confirm that the distance between the tip of the probe and the combustion chamber is at an initially predetermined distance; installing a carbon support film in the stepped hole at the tip of the probe; performing multiple samplings by adjusting the probe according to a set number of cycles, including: collecting smoke particles at the same height at different time points or smoke particles at different heights at the same time point in the combustion chamber; and retrieving the samples collected on the probe; determining that the probe has returned to its initial position and resetting the components of the combustion chamber. This method can collect smoke particles from transformer insulating oil in different aging states at different times and in different spaces, achieving early warning of internal transformer faults; the structure is simple, easy to repair and maintain, and safe and reliable.
