Description

Technical Field

[0001] The invention belongs to the technical field of gas detection, and in particular relates to a detection device for an environmentally friendly insulating mixed gas GIS. Background Art

[0002] C4F7N / C02 mixed environmentally friendly gas is an innovative environmentally friendly gas mixture, mainly composed of perfluoroisobutyronitrile (C4F7N) and carbon dioxide (CO2) mixed in precise scientific proportions. This composite material is particularly valued in the field of electrical engineering because it exhibits excellent insulation performance and dielectric properties, while providing a safer and more reliable working environment in electrical insulation switchgear and substations.

[0003] As an environmentally friendly alternative, the C4F7N / C02 mixed gas shows a smaller global greenhouse gas effect, especially compared with traditional insulating gases such as sulfur hexafluoride (SF6), and its potential impact on global warming is greatly reduced. This mixed gas also has the advantage of being easy to handle because it is gaseous at room temperature and does not require high-pressure storage, making it more cost-effective in transportation and installation.

[0004] GIS (GAS Insulated Switchgear, GIS for short) is a gas-insulated substation, also known as gas-insulated switchgear. The key application areas of C4F7N / C02 mixed environmentally friendly gas include gas-insulated switchgear (GIS) and gas-insulated substation (GIS). In these critical infrastructures, C4F7N / C02 mixed gas provides efficient insulation performance, reduces harmful gas emissions, and is therefore in line with the global pursuit of more sustainable energy solutions. Its environmentally friendly characteristics also make it a viable option that the electrical industry and policymakers are actively considering. With the increasing demand for environmental impact assessments and reducing greenhouse gas emissions, C4F7N / C02 mixed environmentally friendly gas represents a step towards a greener and safer future.

[0044] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0045] The present embodiment provides a detection device for an environmentally friendly insulating mixed gas GIS, which can simultaneously detect the local discharge situation in the environmentally friendly insulating mixed gas in the environmentally friendly insulating mixed gas GIS, the carbon-containing solid matter generated by the discharge, the contamination degree in the environmentally friendly insulating mixed gas, and the volume change of the environmentally friendly insulating mixed gas at different temperatures, which is convenient for subsequent research and has a high detection efficiency.

[0046] like Figure 1 and Fig.10 As shown, in this embodiment, the detection device of the environmentally friendly insulating mixed gas GIS includes a detection platform 1, an equipment platform 3, a conveying pipe group, a telescopic collection pipe (not shown in the figure) and a gas guide device 52. The detection platform 1 is provided with a first detection mechanism (not shown in the figure) and a second detection mechanism (not shown in the figure). The first detection mechanism is used to detect carbon-containing solid substances generated by discharge of the environmentally friendly insulating mixed gas, and the second detection mechanism is used to detect the pollution degree in the environmentally friendly insulating mixed gas. The equipment platform 3 is located below the detection platform 1. The equipment platform 3 is provided with a third detection mechanism 4. The third detection mechanism 4 is used to detect the volume change of the environmentally friendly insulating mixed gas at different temperatures. The telescopic collection pipe is used to collect the environmentally friendly insulating mixed gas. The first detection mechanism, the second detection mechanism and the third detection mechanism 4 are all connected to the telescopic collection pipe through the conveying pipe group (not shown in the figure). One end of the gas guide device 52 is connected to the telescopic collection pipe, and the other end of the gas guide device 52 is used to receive the environmentally friendly insulating mixed gas. The other end of the gas guide device 52 is provided with a discharge detector 55. Specifically, the other end of the gas guide device 52 is located at the observation window of the environmentally friendly insulating mixed gas GIS (not shown in the figure). It can be understood that by setting the detection device of the environmentally friendly insulating mixed gas GIS, the telescopic collecting pipe and the gas guide device 52 are used to receive the environmentally friendly insulating mixed gas in the environmentally friendly insulating mixed gas GIS, and through the observation window of the environmentally friendly insulating mixed gas GIS, the discharge detector 55 detects the local discharge of the environmentally friendly insulating mixed gas in the environmentally friendly insulating mixed gas GIS, and the environmentally friendly insulating mixed gas enters the first detection mechanism, the second detection mechanism and the third detection mechanism 4 respectively through the conveying pipe group for detection, and does not affect each other. It can simultaneously detect the local discharge of the environmentally friendly insulating mixed gas in the environmentally friendly insulating mixed gas GIS, the carbon-containing solid matter generated by discharge, the pollution degree of the environmentally friendly insulating mixed gas, and the volume change of the environmentally friendly insulating mixed gas at different temperatures, which is convenient for subsequent research and has high detection efficiency.

[0047] like Figure 1As shown, in this embodiment, the detection platform 1 and the equipment platform 3 are connected by a plurality of support rods 2 arranged at intervals, the plurality of support rods 2 are arranged vertically, one end of the plurality of support rods 2 are connected to the bottom wall of the detection platform 1, and the other ends of the plurality of support rods 2 are fixedly penetrated through the equipment platform 3 and abut against the ground to fix and support the detection platform 1 and the equipment platform 3. A first mounting plate 5 is vertically arranged above the detection platform 1, the first detection mechanism and the second detection mechanism are spaced apart on the side wall of the first mounting plate 5, the side wall of the detection platform 1 is also connected to a second mounting plate 6, and the telescopic collection pipe is fixedly penetrated through the second mounting plate 6.

[0048] Exemplarily, the discharge detector 55 is a high-sensitivity local discharge light source detection module based on a gallium nitride transmission film with single-photon monitoring sensitivity, which has high detection sensitivity and accurate detection results.

[0049] Further, such as Figure 1 , Figure 2 and Figure 6 As shown, the first detection mechanism includes two symmetrically arranged sedimentation bins 8, and the delivery pipe group includes a first delivery pipe 9 and a second delivery pipe 10. One end of the first delivery pipe 9 is connected to both sedimentation bins 8, one end of the second delivery pipe 10 is connected to both sedimentation bins 8, and the other end of the first delivery pipe 9 and the other end of the second delivery pipe 10 are both connected to the telescopic collection pipe. Specifically, one end of the first delivery pipe 9 is also connected to the third delivery pipe 11, and one end of the first delivery pipe 9 and the end of the third delivery pipe 11 away from the first delivery pipe 9 are each connected to a sedimentation bin 8, so that one end of the first delivery pipe 9 is connected to the two sedimentation bins 8. It can be understood that by setting the first delivery pipe 9 and the second delivery pipe 10, the environmentally friendly insulating mixed gas is simultaneously delivered to the two sedimentation bins 8 through the two delivery pipes, avoiding the situation where the environmentally friendly insulating mixed gas cannot be delivered due to problems with a single delivery pipe, and the stability is strong. The environmentally friendly insulating mixed gas discharges in the two sedimentation bins 8 to generate carbon-containing solid matter and precipitate, so as to detect the amount of carbon-containing solid matter generated by the discharge of the environmentally friendly insulating mixed gas.

[0050] Exemplarily, detection scales are provided on the two sedimentation bins 8 so that the operator can directly check the amount of carbon-containing solid matter generated in the sedimentation bin 8, which is convenient for operation.

[0051] Furthermore, if Figure 1 , Figure 2 and Figure 6As shown, the delivery pipe group also includes a fourth delivery pipe 15, a fifth delivery pipe 16, a connecting pipe 7 connected to the telescopic collection pipe, and two L-shaped pipes 14. The second detection mechanism includes a first detection body (not shown in the figure) and a second detection body (not shown in the figure) that are symmetrically arranged. The first detection body and the second detection body both include a detection chamber 12, and both detection chambers 12 are provided with regulating valves 13, and both regulating valves 13 are connected with L-shaped pipes 14, one end of one L-shaped pipe 14 away from the regulating valve 13 is connected to the fourth delivery pipe 15, and the other end of the L-shaped pipe 14 away from the regulating valve 13 is connected to the fourth delivery pipe 15, the fourth delivery pipe 15 is connected to the connecting pipe 7, and the fifth delivery pipe 16 is connected to the telescopic collection pipe. Specifically, the connecting pipe 7 is located below the telescopic collection pipe. It can be understood that by setting the above pipelines, two pipelines are formed to detect the environmentally friendly insulating mixed gas transported by the first detection body and the second detection body respectively, so as to meet the first detection body and the second detection body can simultaneously detect the pollution degree of the environmentally friendly insulating mixed gas, so as to improve the accuracy of the detection.

[0052] Furthermore, if Figure 5 As shown, a vertically arranged metering plate 36 is provided between the two detection chambers 12 , a metering tube 37 is vertically arranged on the side wall of the metering plate 36 , and a button switch 38 matched with the metering tube 37 is provided on the side wall of the metering plate 36 .

[0053] Furthermore, if Figure 1 As shown, the detection device of the environmentally friendly insulating mixed gas GIS also includes a gas transmission mechanism (not shown in the figure), which is arranged on the equipment platform 3. The gas transmission mechanism includes a first delivery pump 17 and a second delivery pump 18. The delivery pipe group also includes two discharge pipes. The two detection chambers 12 are respectively connected to the first delivery pump 17 and the second delivery pump 18 through the discharge pipes to extract the environmentally friendly insulating mixed gas into the detection chamber 12 to ensure that the detection chamber 12 is filled with environmentally friendly insulating mixed gas, so as to improve the objectivity and accuracy of the detection of the pollution degree of the environmentally friendly insulating mixed gas.

[0054] Furthermore, if Figure 1 As shown, the conveying pipe group also includes a U-shaped pipe 19, one end of the U-shaped pipe 19 is connected to the third detection mechanism 4, and the other end of the U-shaped pipe 19 is connected to the connecting pipe 7. It can be understood that since the connecting pipe 7 is arranged below the telescopic collecting pipe, and the third detection mechanism 4 is located below the detection platform 1, the connecting pipe 7 is close to the third detection mechanism 4, and the third detection mechanism 4 and the connecting pipe 7 are directly connected through the U-shaped pipe 19, which avoids the need to set a long pipeline outside the detection platform 1 and the equipment platform 3, saves pipeline materials, and avoids interference between pipelines, which is convenient for sorting.

[0055] For example, Figure 3As shown, the third detection mechanism 4 is provided with an air pressure regulating plate 27 and a buffer rod 28, the buffer rod 28 is inserted into the air pressure regulating plate 27, one end of the buffer rod 28 is connected to the top wall of the third detection mechanism 4, the air pressure regulating plate 27 can move along the length direction of the buffer rod, and the buffer rod 28 is sleeved with a first return spring 29 located between the inner wall of the third detection mechanism 4 and the air pressure regulating plate 27, and a movable plate 30 is provided at one end of the air pressure regulating plate 27 away from the elastic member, and the movable plate 30 can move relative to the side wall of the third detection mechanism 4 to drive the air pressure regulating plate 27 to move along the length direction of the buffer rod. Specifically, one end of the U-shaped tube 19 passes through the top wall of the third detection mechanism 4 and is connected to the interior of the third detection mechanism 4. It can be understood that when the volume change of the environmentally friendly insulating mixed gas at different temperatures is detected, the first driver 31 is turned on to drive the first gear 32 to rotate, thereby driving the movable plate 30 and the air pressure regulating plate 27 to move in the vertical direction, and then the volume of the environmentally friendly insulating mixed gas entering the third detection mechanism 4 is preliminarily limited, and the temperature regulator 41 is turned on to adjust the temperature in the third detection mechanism 4, so as to detect the volume change of the environmentally friendly insulating mixed gas after being affected by temperature according to the deformation of the first reset spring 29. This process can automatically preliminarily limit the environmentally friendly insulating mixed gas entering the third detection mechanism 4, is easy to operate, and has strong stability.

[0056] Furthermore, if Figure 3 As shown, a first driver 31 is provided on the side wall of the third detection mechanism 4, and the output end of the first driver 31 is connected to a first gear 32, a first rack (not shown in the figure) meshing with the first gear 32 is provided on the side wall of the movable plate 30, and a movable temperature control mechanism (not shown in the figure) is provided at one end of the air pressure regulating plate 27 away from the first return spring 29, and the movable temperature control mechanism can move along the length direction of the air pressure regulating plate 27. Specifically, the first rack is provided on the side wall of the movable plate 30 in the vertical direction. It can be understood that by setting the above-mentioned driving structure, when it is necessary to limit the volume of the environmentally friendly insulating mixed gas entering the third detection mechanism 4, the first driver 31 is turned on to drive the first gear 32 to rotate, thereby driving the movable plate 30 and the air pressure regulating plate 27 to move in the vertical direction, and then the volume of the environmentally friendly insulating mixed gas entering the third detection mechanism 4 is limited, and the operation is convenient.

[0057] Furthermore, if Figure 3 and Figure 8As shown, the movable temperature control mechanism includes a movable plate 40 along the length direction of the air pressure regulating plate 27, and the movable plate 40 is slidably connected to the air pressure regulating plate 27, a temperature regulator 41 is arranged on the side wall of the movable plate 40, and the movable plate 40 is provided with a mounting channel 42 extending to the side wall of the movable plate 40 along its length direction, a second driver 43 is arranged on the side wall of the air pressure regulating plate 27, and the output end of the second driver 43 is connected to a second gear 44, and the inner wall of the mounting channel 42 is provided with a second rack meshing with the second gear 44 (not shown in the figure). Specifically, the movable plate 40 is arranged horizontally, the movable plate 40 is slidably connected to the bottom wall of the air pressure regulating plate 27, the temperature regulator 41 is movably connected to the side wall of the movable plate 40, the second gear 44 is a different gear, and the mounting channel 42 is provided with a second rack meshing with the second gear 44 on both side walls in the vertical direction, and the second rack extends in the horizontal direction. It can be understood that the gear with only partial teeth is driven by the second driver 43 to rotate the gear, and cooperates with the two second racks on the inner wall of the installation channel 42 to realize the movement of the movable plate 40 relative to the air pressure regulating plate 27, so as to drive the temperature regulator 41 to reciprocate in the length direction (i.e., horizontal direction) of the air pressure regulating plate 27, so as to more evenly adjust the temperature in the third detection mechanism 4 to improve the detection accuracy. It should be noted that the gear is a prior art, and its specific structure and movement mode will not be described in detail in this embodiment.

[0058] For example, Fig. 9 As shown, a fire extinguishing box 45 is provided on the bottom wall of the third detection mechanism 4, and an exhaust port 46 connected to the outside is provided on the side wall of the fire extinguishing box 45, a horizontally arranged third mounting plate 47 is provided on the side wall of the fire extinguishing box 45, and a horizontally arranged fourth mounting plate 48 is slidably connected to the side wall of the fire extinguishing box 45, the third mounting plate 47 and the fourth mounting plate 48 are connected by a second reset spring 49, a counterweight tin block 50 and a sliding baffle 51 are provided on the bottom wall of the fourth mounting plate 48, the sliding baffle 51 is slidably connected to the side wall of the fire extinguishing box 45, and the sliding baffle 51 is matched with the exhaust port 46. It can be understood that when the mobile temperature control mechanism in the third detection mechanism 4 heats up abnormally, the temperature in the third detection mechanism 4 will rise rapidly. At this time, the counterweight tin block 50 melts, and the fourth mounting plate 48 and the sliding baffle 51 move in the vertical direction under the action of the second return spring 49, so that the exhaust port 46 opens, thereby releasing the fire extinguishing agent in the fire extinguishing box 45 into the third detection mechanism 4, thereby preventing fire inside the third detection mechanism 4, and having higher safety.

[0059] Furthermore, if Figure 1As shown, the delivery pipe group also includes a sixth delivery pipe 20 and a seventh delivery pipe 21, one end of the sixth delivery pipe 20 is connected to the middle of the seventh delivery pipe 21, and the other end of the sixth delivery pipe 20 is connected to the telescopic collection pipe, one end of the seventh delivery pipe 21 is fixedly connected to a detection unit (not shown in the figure), and the other end of the seventh delivery pipe 21 is provided with an auxiliary purification mechanism (not shown in the figure). Specifically, the detection unit is used to detect whether there is harmful gas in the detection device of the environmentally friendly insulating mixed gas GIS, that is, whether there is harmful gas mixed in the environmentally friendly insulating mixed gas, and the auxiliary purification mechanism is used to purify the harmful gas mixed in the environmentally friendly insulating mixed gas. It can be understood that the seventh delivery pipe 21 is connected to the sixth delivery pipe 20, and the other end of the sixth delivery pipe 20 is connected to the telescopic collection pipe. When the detection unit detects harmful gas mixed in the environmentally friendly insulating mixed gas, it will send a signal. After the operator obtains the signal, it drives the auxiliary purification mechanism to remove the harmful gas mixed in the environmentally friendly insulating mixed gas.

[0060] For example, Figure 1 and Figure 7 As shown, the auxiliary purification mechanism includes a horizontally arranged purification chamber 33, one end of the purification chamber 33 is connected to a purification pipe 34, and the other end of the purification chamber 33 is slidably connected to a push plug 35, the purification pipe 34 is connected to the seventh delivery pipe 21, and a fixing buckle 39 matched with the purification pipe 34 is provided on the side wall of the first mounting plate 5 to fix the purification pipe 34, so as to facilitate driving the push plug 35, and a purifier is stored in the purification chamber 33. After driving the push plug 35, the purifier will enter the telescopic collection pipe through the seventh delivery pipe 21 and the sixth delivery pipe to purify the harmful gas mixed in the environmentally friendly insulating mixed gas, and it is convenient to send the purifier into the entire detection device, thereby reducing the adverse effects of the harmful gas mixed in the environmentally friendly insulating mixed gas. In addition, a color display ball (not shown in the figure) or other display components can be set on the detection unit. When the detection unit detects the harmful gas mixed in the environmentally friendly insulating mixed gas, the color change of the color display ball or the display of other display components can be used to remind the operator to convey the situation of the harmful gas mixed in the environmentally friendly insulating mixed gas. The detection principle of the detection unit and the specific use of the color display ball are both existing technologies and are not specifically limited in this embodiment.

[0061] It should be noted that multiple control valves are provided on the multiple delivery pipelines in the delivery pipe group, and the multiple control valves can control the connection status of the delivery pipeline with other structural connection nodes, as well as the connection status between the pipelines, etc. The specific installation position and quantity can be determined according to specific use requirements, and this embodiment does not make specific restrictions. In addition, the gas transmission mechanism includes multiple delivery pumps, not just the first delivery pump 17 and the second delivery pump 18. The multiple delivery pumps act on the multiple delivery pipelines in the delivery pipe group. The connection mode and quantity of other pipelines and other delivery pumps can be determined according to specific use requirements, and this embodiment does not make specific restrictions.

[0062] Furthermore, if Figure 1 and Figure 4 As shown, the telescopic collecting tube includes a first collecting tube 22, a second collecting tube 23 and a third collecting tube 24. The third collecting tube 24 can be slidably connected to the second collecting tube 23 along its axial position, and at least a part of the third collecting tube 24 is located in the second collecting tube 23. The second collecting tube 23 can be slidably connected to the first collecting tube 22 along its axial position, and at least a part of the second collecting tube 23 is located in the first collecting tube 22. The first collecting tube 22 is provided with a first movable buckle 25 that cooperates with the second collecting tube 23 and is used to fix the position of the second collecting tube 23 relative to the first collecting tube 22. The second collecting tube 23 is provided with a second movable buckle 26 that cooperates with the third collecting tube 24 and is used to fix the position of the third collecting tube 24 relative to the second collecting tube 23. It can be understood that when it is necessary to directly collect and detect the environmentally friendly insulating mixed gas in the environmentally friendly insulating mixed gas GIS, the height of the second collection tube 23 and the third collection tube 24 is adjusted relative to the first collection tube 22 to form a longer collection tube to collect the environmentally friendly insulating mixed gas at different heights in the environmentally friendly insulating mixed gas GIS, so as to improve the accuracy and objectivity of the detection.

[0063] Furthermore, if Fig.10 As shown, the detection device of the environmentally friendly insulating mixed gas GIS also includes a display module 56, and the discharge detector 55 is electrically connected to the display module 56. It can be understood that by setting the display module 56, it is convenient for the operator to obtain the detection result of the discharge detector, and it is convenient for the operator to understand the partial discharge of the environmentally friendly insulating mixed gas in the environmentally friendly insulating mixed gas GIS, so as to facilitate further research on the environmentally friendly insulating mixed gas. The discharge detector 55 and the display module 56 can be electrically connected wirelessly or wired, which is a prior art and is not specifically limited in this embodiment.

[0064] Furthermore, the gas guide device 52 is also connected with an axial flow tube 53 and a connecting valve 54. Whether the axial flow tube 53 and the telescopic collecting tube are connected is controlled by the connecting valve 54. Specifically, the axial flow tube 53 is connected to the first collecting tube 22 of the telescopic collecting tube. The axial flow tube 53 is provided to facilitate guiding the environmentally friendly insulating mixed gas in the environmentally friendly insulating mixed gas GIS into the gas guide device and then into the telescopic collecting tube, and the operation is simple.

[0065] In this embodiment, the environmentally friendly insulating mixed gas is a C4F7N / C02 mixed environmentally friendly gas. The working process of the detection device of the environmentally friendly insulating mixed gas GIS is as follows: through the observation window of the detected environmentally friendly insulating mixed gas GIS, the discharge detector 55 detects the local discharge of the C4F7N / C02 mixed environmentally friendly gas inside the C4F7N / C02 mixed environmentally friendly gas GIS, and displays it through the display module 56. The collected C4F7N / C02 mixed environmentally friendly gas is injected into the first collecting tube 22 of the telescopic collecting tube through the axial flow tube 53. The conduction between the axial flow tube 53 and the first collecting tube 22 can be controlled by the connecting valve 54. The C4F7N / C02 mixed environmentally friendly gas enters the sedimentation bin 8 through the sixth delivery pipe 20 and the first delivery pipe 9, and the C4F7N / C02 mixed environmentally friendly gas discharges in the sedimentation bin 8 to generate carbon-containing solid matter for precipitation, thereby detecting the dust content in the C4F7N / C02 mixed environmentally friendly gas, and the C4F7N / C02 mixed environmentally friendly gas enters the detection bin 12 through the fifth delivery pipe 16 and the L-shaped pipe 14 for pollution detection, the second delivery pump 18 is turned on, and the C4F7N / C02 mixed environmentally friendly gas is delivered to the third detection mechanism 4 through the U-shaped pipe 19, the first driver 31 is turned on to drive the first gear 32 to rotate, thereby driving the moving plate 30 and the air pressure regulating plate 27 to move in the vertical direction, and then the volume of the C4F7N / C02 mixed environmentally friendly gas entering the third detection mechanism 4 is limited, the temperature regulator 41 is turned on to adjust the temperature in the third detection mechanism 4, and the C4F7N / C02 mixed environmentally friendly gas is detected according to the deformation of the first return spring 29. The volume change after the temperature influence, when the detection unit detects the harmful gas mixed in the C4F7N / C02 mixed environmentally friendly gas, the auxiliary purification mechanism is driven to send the purifier into the entire detection device, thereby reducing the adverse effects of the harmful gas mixed in the C4F7N / C02 mixed environmentally friendly gas. When it is necessary to directly collect and detect the C4F7N / C02 mixed environmentally friendly gas in the environmentally friendly insulating mixed gas GIS, the first collection tube 22, the second collection tube 23, and the third collection tube 24 are adjusted to collect the C4F7N / C02 mixed environmentally friendly gas at different heights in the environmentally friendly insulating mixed gas GIS. When the mechanical abnormal temperature in the third detection mechanism 4 rises, the temperature in the third detection mechanism 4 rises rapidly. At this time, the counterweight tin block 50 melts, and the fourth mounting plate 48 and the sliding baffle 51 move in the vertical direction under the action of the second return spring 49, so that the exhaust port 46 is opened, thereby releasing the fire extinguishing agent in the fire extinguishing box 45 into the third detection mechanism 4, thereby preventing the third detection mechanism 4 from catching fire.
