The equipment uses its cooling, arc extinguishing and insulation functions to provide good conditions for the normal operation of electrical equipment. However, when there is a problem with the operating status of the equipment, the insulating oil inside the equipment will undergo different changes due to the influence of equipment discharge or temperature rise. The industry usually monitors the indicators of different parameters in the insulating oil to promptly detect abnormal operating conditions in hidden parts of the equipment. For example, if the oil contains excessive acetylene, it can be considered that there is discharge or overheating inside the transformer, and the transformer should be shut down for inspection and maintenance in time to avoid serious safety accidents such as transformer fires.

DETAILED DESCRIPTION

[0039] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0040] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which this application belongs.

[0041] The technical solution of the embodiment of the present application is to solve the above technical problems, and the overall idea is as follows:

[0042] Example 1

[0043] Reference Figure 1 The insulating oil collection device 1 provided in the embodiment of the present application includes a collection component 2 and a suspension component 3, wherein the collection component 2 is used to flexibly connect to the oil production port 4 of the equipment to be collected so as to collect and accommodate the sample to be tested; the collection component 2 includes at least one first container 21, the first container 21 has an oil inlet 22 and an oil outlet 23, and the oil inlet 22 is used to flexibly connect to the oil production port 4; the suspension component 3 is movably arranged on the collection component 2, and is used to flexibly hang on the oil production port 4, and the suspension length of the suspension component 3 is adjustable to adjust the collection height of the collection component 2.

[0044] Specifically, in order to solve the problem in the prior art that the collection of insulating oil requires the cooperation of multiple people, is time-consuming and labor-intensive, and cannot avoid the interference or pollution of the insulating oil sample by ridges or dust, the insulating oil collection device 1 provided in this embodiment realizes single-person oil collection through the setting of the suspension component 3, without the need for the cooperation of others to lift and the like; and the adjustable suspension length of the suspension component 3 is used to adjust the collection height of the collection component 2, so that the collection device is suitable for equipment to be collected that cannot be raised, thereby improving versatility; at the same time, the first container is provided with an oil inlet 22 and an oil outlet 23, and the flow direction from the oil inlet 22 to the oil outlet 23 is from the opposite direction of the gravity direction to the gravity direction, so that when the sample to be tested is collected, the air in the first container can be completely discharged through the flow of the sample to be tested, thereby avoiding the pollution or interference of air or dust on the sample to be tested, and effectively improving the detection accuracy.

[0045] Among them, the collection component 2 can be movably connected to the oil production port 4 of the equipment to be collected to collect and contain the samples to be tested. Specifically, the collection component 2 includes at least one first container 21, which is mainly used to collect and contain the samples to be tested. After collection, the first container 21 is removed for testing. It can be understood that: the collection component 2 provides a mounting position for at least the first container 21, and the collection component 2 can have a supporting plate or a hanging plate and other structures to detachably install at least one first container 21. In addition, it can be understood that: in order to ensure the service life of the entire collection device, the material of the collection component 2 can be set to be corrosion-resistant, such as stainless steel in this embodiment.

[0046] Among them, the suspension component 3 is used for active suspension on the oil production port 4. If sampling is required, the collection component 2 is suspended on the oil production port 4 through the suspension component 3, thereby connecting the oil production port 4 and the oil inlet 22; the suspension component 3 can include at least a suspension rope 31, a suspension rod, etc., and in this embodiment, the suspension component 3 is set to have an adjustable suspension length, for example: the length of the suspension rope 31 or the suspension rod is adjusted, thereby adjusting the collection height of the collection component 2 to be suitable for equipment to be collected at different heights.

[0047] The first container 21 has a containing space for containing the sample to be tested. After the collection is completed, the first container 21 is taken away for testing of the sample to be tested, and then another first container 21 is replaced for sampling here; the structure of the first container 21 limits the flow direction of the sample to be tested from the oil inlet 22 to the oil outlet 23 from the opposite direction of the gravity direction to the gravity direction, that is, in practice, it enters from the bottom and accumulates upward, thereby accumulating all the air in the first container 21 upward, avoiding the inherent air in the first container 21. The dust will interfere with or pollute the sample to be tested and affect the detection result; during actual sampling, the oil outlet 23 can be kept to discharge oil for 30s-60s, so as to ensure that the sample to be tested in the first container 21 is full by discharging the sample to be tested for a period of time, ensuring that there is no air inside the first container 21, and also avoiding that part of the sample to be tested that is contaminated by the inherent air in the first container 21 will remain in the first container 21, so that the first container 21 can collect the sample to be tested for both gas content detection and particle size detection. Specifically, when the collection of the first container 21 is completed, the oil outlet 23 needs to be blocked first, and then the oil inlet 22 needs to be blocked.

[0048] Among them, refer to the attached Figure 1 The first container 21 can be connected to the oil production port 4 by a connecting pipe of a rubber hose 5. The diameter of the oil inlet 22 is smaller than that of the rubber hose 5, so that when connected, the inner wall of the rubber hose 5 can be tightly attached to the outer wall of the oil inlet 22 to prevent air or dust from entering and causing interference or contamination to the sample to be tested. In addition, after the collection of the first container 21 is completed, the rubber hose 5 needs to be cut off and tightened, for example: the rubber hose 5 is divided into three sections for cut-off and tightening, so as to ensure that no additional air or dust will enter the direction of the oil inlet 22 and cause contamination to the sample to be tested.

[0049] According to the above, the insulating oil collection device 1 provided in the first aspect of the present application can adjust the collection height of the collection component 2 by adjusting the hanging length of the hanging component, so that it can adapt to different equipment to be collected, and does not require the cooperation of multiple people to lift, which is convenient and efficient; at the same time, at least one first container 21 is provided on the collection component 2, and the flow collection of the sample to be tested is realized by setting the oil inlet 22 and the oil outlet 23, and the flow is carried out from bottom to top, so that the gas in the first container 21 can be completely discharged, effectively avoiding the pollution or interference of air and dust on the sample to be tested; effectively solving the problem in the prior art that the collection of insulating oil requires the cooperation of multiple people, is time-consuming and labor-intensive, and cannot avoid the interference or pollution of the insulating oil sample by ridges or dust.

[0050] The term "and / or" in this article is merely a description of the association relationship of associated objects, indicating that three relationships may exist, for example, A and / or B, which is specifically understood as: A and B may be included at the same time, A may exist alone, or B may exist alone, and any of the above three situations may exist.

[0051] Further, see Attachment Figure 2 In the insulating oil collection device 1 provided in this embodiment, in a specific implementation, the suspension component 3 includes a suspension rope 31 and an adjusting member 32; the adjusting member 32 is movably arranged on the collection component 2 so as to be able to be locked or loosened relative to the collection component 2; one end of the suspension rope 31 is fixedly connected to the collection component 2, and the other end is movably connected to the adjusting member 2 so as to adjust the suspension length of the suspension rope 31.

[0052] Specifically, in order to achieve the adjustable hanging length of the hanging component 3, the hanging component 3 is configured to include a hanging rope 31 and an adjusting member 32 in this embodiment; the hanging rope 31 is a rope body made of a soft, wear-resistant and corrosion-resistant material, such as a steel wire rope or a polytetrafluoroethylene rope. The adjusting member 32 is a rigid structure, such as a screw, which can be tightened or loosened relative to the collection component 2; the setting mode of the hanging hook 31 can be selected to be fixed to the collection component 2 at one end, and the other end is a free end or fixed to the adjusting member 32. When the hanging length needs to be adjusted, the end connected to the adjusting member 32 is wound relative to the adjusting member 32, and the number of windings can be based on actual needs, and then the adjusting member 32 is locked to ensure the stable suspension of the hanging rope 31.

[0053] Further, see Attachment Figure 4 In the insulating oil collection device 1 provided in this embodiment, in a specific implementation, a slot 33 is provided at one end of the adjusting member 32 away from the collection component 2 to fix the suspension rope 31 .

[0054] Specifically, in order to ensure the suspension stability of the suspension rope 31 and prevent it from falling off the adjusting member 32, a slot 33 is provided at one end of the adjusting member 32 away from the collecting assembly 2 in this embodiment. The adjusting member 32 is in the form of a screw, and the slot 33 extends along the axial direction of the screw, so that the suspension rope 31 passes through and is fixed in the slot 33 during the winding process, thereby increasing the suspension stability of the suspension rope 31. The number of the slots 33 is not limited here, and can be designed and adjusted according to actual needs, for example: refer to the attached Figure 4 , four are evenly distributed around the axis of the screw, and an X-shaped clamping track can be performed to improve stability.

[0055] Further, see Attachment Figure 1 In the insulating oil collection device 1 provided in this embodiment, in a specific implementation, the collection component 2 includes a carrier 24; the carrier 24 is movably connected to the suspension component 3, and the carrier 24 has a first surface 241 and a second surface 242 opposite to each other; the at least one first container 21 is detachably arranged on the first surface 241 of the carrier 24 so that the second surface 242 of the carrier 24 faces the equipment to be collected.

[0056] Specifically, in order to realize the detachability of the first container 21 relative to the collection component 2, a carrier 24 is provided in this embodiment. The carrier 24 can be plate-shaped, groove-shaped, frame-shaped, etc. In this embodiment, the carrier 24 is preferably provided as a plate-shaped structure, which is provided in the vertical direction, and then when the first surface 241 is connected to the first container 21, the second surface 242 can face the device to be collected, so as to avoid collision or friction between the first container 21 and the device to be collected, and no other support is required; and in this embodiment, the carrier 24 is provided as a U-shaped structure, the first surface 241 is a concave side surface, and the second surface 242 is a protruding side surface. The at least one first container 21 is provided on the first surface 241 to protect it to a certain extent, and avoid collision or friction by other tools or personnel. The carrier 24 can be made of corrosion-resistant material, such as steel plate, and in order to reduce the overall mass of the collection device, polytetrafluoroethylene material can be selected. In order to achieve the connection of the suspension rope 31, in this embodiment, hanging ears can be set on opposite sides of one end of the carrier 24 to facilitate the insertion of the suspension rope 31. This setting can be easily understood by those skilled in the art and will not be elaborated on here.

[0057] Further, see Attachment Figure 2In the insulating oil collection device 1 provided in this embodiment, in a specific implementation, the first container 21 includes a first tube body 211, a second tube body 212 and a third tube body 213; the first tube body 211, the second tube body 212 and the third tube body 213 are arranged in parallel in the horizontal direction, and the first tube body 211, the second tube body 212 and the third tube body 213 are extended in the vertical direction;

[0058] Among them, the upper end of the first tube body 211 is the oil inlet 22, and the lower end of the first tube body 211 is connected to the lower end of the second tube body 212; the upper end of the second tube body 212 is connected to the upper end of the third tube body 213, and the lower end of the third tube body 213 is the oil outlet 23 for active oil discharge.

[0059] Specifically, in order to realize the air discharge of the first container 21, in this embodiment, the first container 21 is configured to include a first tube body 211, a second tube body 212 and a third tube body 213 arranged side by side in the horizontal direction and extending in the vertical direction; the upper end of the first tube body 211 serves as the oil inlet 22, and the lower end is connected to the lower end of the second tube body 212, so that after the oil inlet 22 is filled with oil, the second tube body 212 needs to be filled from bottom to top, so that the air in the first container 21 can be squeezed upward and passed through the third tube body 213 to the oil outlet 23 At this time, the oil discharge of the sample to be tested needs to be maintained for a period of time, for example, 30s-60s, to ensure that the samples to be tested in the first container 21 are all samples to be tested that are not disturbed or contaminated; at the same time, in order to speed up the collection rate, in this embodiment, the diameters of the first tube body 211 and the third tube body 213 are set to be smaller than the diameter of the second tube body 212. The second tube body 212 serves as the main accommodating space for the sample to be tested. The first tube body 211 and the third tube body 213 are quickly filled with smaller diameters to quickly discharge air, dust and contaminated samples to be tested.

[0060] Further, see Attachment Figure 3 and attached Figure 5 In the insulating oil collection device 1 provided in this embodiment, in a specific implementation, the collection component 2 also includes an oil guide plate 25; the oil guide plate 25 is arranged on the supporting member 24 and is located below the at least one first container 21, and the oil guide plate 25 forms a preset angle with the horizontal direction to guide the oil to one side of the supporting member 24, and the oil guide plate 25 is inclined from the supporting member 24 to the first container 21.

[0061] Specifically, in order to facilitate the collection of the insulating oil discharged from the oil outlet 23, an oil guide plate 25 is provided at the lower end of the first surface 241 of the carrier 24 corresponding to the first container 21 in this embodiment. The oil guide plate 25 is a plate-like structure and needs to be made of a corrosion-resistant material, such as stainless steel or lightweight polytetrafluoroethylene. The oil guide plate 25 is preferably integrally formed with the carrier 24 to avoid oil leakage due to poor sealing at the connection between the two. In order to realize that the oil guide plate 25 can receive the insulating oil discharged from the oil outlet 23 on the one hand, and on the other hand, it is also necessary to guide the discharged insulating oil for centralized collection, in this embodiment, the oil guide plate 25 is set to be at a preset angle with the horizontal direction, for example: 20 degrees to 60 degrees, refer to the attached Figure 5 , that is, the oil guide plate 25 is tilted to guide the insulating oil along the tilted direction thereof, so that the insulating oil discharged from the oil outlet 23 can flow along the tilted direction of the oil guide plate for centralized collection, for example, a collection bucket or a collection basin is placed below the end of the oil guide plate 25. At the same time, in order to prevent the insulating oil from overflowing at the end of the oil guide plate 25 away from the carrier 24, in this embodiment, the oil guide plate 25 is arranged to be tilted from the carrier 24 toward the first container 21, that is, the end of the oil guide plate 25 away from the carrier 24 is higher than the end thereof connected to the carrier 14, thereby ensuring that the insulating oil always flows along the connection between the oil guide plate 25 and the carrier 24.

[0062] Further, see Attachment Figure 3 and attached Figure 5 In the insulating oil collection device 1 provided in this embodiment, in a specific implementation, an oil guide groove 251 is provided on the oil guide plate 25; an accommodating groove 252 is provided on the end of the oil guide plate 25 which is farther away from the first container 21 in the vertical direction, for accommodating a counterweight (not shown in the figure).

[0063] Specifically, in order to further ensure the guiding property of the oil guide plate 25, in this embodiment, the oil guide groove 251 is provided on the oil guide plate 25 along its inclined direction to guide the insulating oil; preferably, the oil guide groove 251 is provided at the connection between the oil guide plate 25 and the bearing member 24, which simplifies the process and facilitates molding. Figure 1When multiple first containers 21 are fixed on the carrier 24 at the same time and sampling cannot be performed simultaneously, once the first container 21 in the opposite direction of the oil guide plate 25 is filled, the carrier 24 will tilt so that the insulating oil discharged from the oil outlet 23 will not flow along the oil guide plate 25 to the receiving barrel, causing the insulating oil to overflow or even pollute the environment. In this embodiment, a receiving groove 252 is set at the end of the oil guide plate 25 that is farther away from the first container 21 in the vertical direction. The shape and size of the receiving groove 252 are not limited here, as long as they are compatible with the counterweight. When the above-mentioned weight causes tilting, the counterweight is placed in the receiving groove 252 to keep the carrier 24 or the oil guide plate 25 in the original tilting direction. Of course, it can be understood that the aforementioned rubber hose 5 can be set in a one-point-multiple form, that is, a form of one inlet and multiple outlets, so that multiple first containers 21 can be collected simultaneously.

[0064] Further, see Attachment Figure 2 and attached Figure 3 In the insulating oil collection device 1 provided in this embodiment, in a specific implementation, the collection assembly 2 includes at least one first fixing portion 26 and at least two plungers 27; the first fixing portion 26 is fixed to the first surface 241 of the carrier 24, and the first fixing portion 26 has a accommodating space along the vertical direction and opens upward to accommodate the first container 21; the at least two plungers 27 correspond to the oil inlet 22 and the oil outlet 23 respectively, and the plunger 27 is inclined along one end face of its axial direction.

[0065] Specifically, in order to realize the detachable connection between the first container 21 and the carrier 24, in this embodiment, at least one first fixing portion 26 is provided on the first surface 241 of the carrier 24. The first fixing portion 26 is fixed on the first surface 241 to provide a placement position or a supporting position for the first container 21. The first fixing portion 26 may be a groove-shaped structure. When it is arranged on the first surface 241, the groove faces upward to facilitate the insertion of the first container 21. Figure 3As shown, the first fixing portion 26 is configured to include two arc-shaped plates 261 and a straight plate 262; the two arc-shaped plates 261 are relatively arranged in a direction perpendicular to the first surface 241 to enclose a receiving space between the two arc-shaped plates 261, and the straight plate 262 is arranged between the two arc-shaped plates 261 to form a supporting portion. In actual use, the bottom of the second tube body 211 is supported on the straight plate 262, and the first tube body 211 and the third tube body 213 are respectively suspended on both sides of the straight plate 262, thereby ensuring the receiving space while reducing the weight of the first fixing portion 26. At the same time, in order to ensure that the sample to be tested inside the first container 21 is not contaminated after it is separated from the carrier 24, in this embodiment, two plungers 7 are set corresponding to one first container 21, and the diameter of the plunger 7 needs to be slightly larger than the diameter of the first tube body 211 and the third tube body 213 to ensure that the plunger 7 is inserted into the oil inlet 22 and the oil outlet 23 to achieve an interference fit with the tube openings; and in this embodiment, one end face of the plunger 7 is set as an inclined end face, and when the oil outlet 23 is blocked, the inclined end face is directed toward the oil outlet 23 to ensure that the insulating oil discharged from the oil outlet 23 always flows out of the inclined end face, so as to avoid air or dust from entering and causing contamination of the sample to be tested.

[0066] Further, see Attachment Figure 1 and attached Figure 2 In the insulating oil collection device 1 provided in this embodiment, in a specific implementation, the collection component 2 also includes at least one second container 28; the second container 28 is detachably arranged on the first surface 241 of the carrier 24, and the second container 28 has an opening 281 to flexibly connect to the oil production port 4, and the second container 28 is transparent.

[0067] Specifically, since the particle size detection is less affected by the air, in order to simplify the collection process, at least one second container 28 is also provided in this embodiment. The second container 28 only needs to have an opening 281 for oil intake. Since there is no need to drain the oil, there is no need to have an oil outlet. At the same time, in order to facilitate observation by the sampling personnel, the second container 28 is set to be transparent in this embodiment, for example, glass material is selected, so that it can be directly judged whether the second container 28 is full during the sampling process.
