Description

Technical Field

[0001] The present invention relates to the technical field of power status monitoring, and in particular to an installation structure of a quick-detachable GIS equipment monitoring sensor. Background Art

[0002] A gas-insulated switchgear (GIS) is a type of integrated electrical equipment that encloses circuit breakers, disconnectors, earthing switches, current transformers, voltage transformers, lightning arresters, and busbars within a grounded metal casing. The interior is filled with 0.4-0.6 MPa of SF6 gas for insulation and arc extinguishing. GIS equipment has seen widespread adoption in recent years due to its high operational reliability, long maintenance cycles, and compact footprint. With the increasing number of operational devices and increased operating time, the risk of equipment failure increases. If maintenance personnel fail to promptly detect potential faults, grid accidents are highly likely to occur. The safety of GIS equipment is directly related to the purity of SF6 gas. Existing SF6 gas monitoring technologies within GIS fall into two main categories: offline monitoring, which relies primarily on post-gas sampling and testing to determine whether the SF6 gas meets operational requirements. This requires significant staff input and cannot guarantee timely detection of early faults. Online monitoring, on the other hand, relies on sensors installed on GIS equipment to monitor SF6 gas purity.

[0003] The Chinese invention patent with patent application number CN201510877169.X relates to a gas-insulated metal-enclosed switchgear and a gas density monitoring device thereof. The gas density monitoring device includes a monitoring gas circuit for corresponding communication with a three-phase gas chamber. A density relay is provided on the monitoring gas circuit. Three ventilation joints are connected in series with the corresponding three-phase gas chambers on the monitoring gas circuit. Each ventilation joint is provided with a gas chamber connecting section for communicating with the corresponding phase gas chamber. An on-off valve is provided on the gas chamber connecting section of each ventilation joint. When it is necessary to monitor the density of the gas in a single-phase gas chamber, the on-off valves on the ventilation joints corresponding to the other two gas chambers can be closed to cut off the communication between the other two phase gas chambers and the monitoring gas circuit, thereby realizing density monitoring of the gas inside the single-phase gas chamber. During monitoring, there is no need to frequently disassemble the corresponding gas circuit connection, which can effectively ensure the airtightness of the connection and facilitate the operation of single-phase gas chamber density monitoring.

[0004] Chinese utility model patent application number CN202021097929.8 discloses a gas composition detection device for GIS equipment. The device comprises a three-way air chamber with a first air inlet, a first air outlet, and a gas supply port. The first air inlet is hermetically connected to the GIS body to be tested and is used to introduce gas from the GIS. A gas absorption cell is provided with a second air inlet at the bottom, hermetically connected to the first air inlet via a self-sealing valve. The gas absorption cell has a light inlet and a light outlet on the left and right sides of its top, respectively. A reflector assembly is provided within the gas absorption cell to reflect light incident through the light inlet multiple times to the light outlet. A spectral analysis system comprises a light supply assembly for providing detection light to the light inlet and a light receiving and detection assembly for receiving and processing light emitted from the light outlet to achieve gas detection. The device is easy to install, and its online monitoring system enables live detection without affecting the normal operation of the GIS equipment.

[0005] In actual engineering applications, online monitoring using sensors is often achieved through inaccessible sensors, which cannot penetrate the interior of the GIS air chamber for measurement. This results in a certain blind spot, preventing the full reflection of the internal conditions. If a sensor fails during operation, it should be replaced without disrupting GIS equipment operation. Currently, no relevant technical reports have been found.

[0006] Therefore, it is necessary to design an installation structure that can extend the sensor into the GIS for measurement without changing the physical characteristics of the GIS equipment, and when the sensor fails, it can be replaced without affecting the operation of the GIS and without power outage.

DETAILED DESCRIPTION

[0041] The present invention will be described in detail below with reference to specific embodiments. The following embodiments will help those skilled in the art to further understand the present invention, but are not intended to limit the present invention in any form. It should be noted that, for those skilled in the art, several variations and improvements can be made without departing from the scope of the present invention. These all fall within the scope of protection of the present invention.

[0042] The embodiment of the present invention provides a quick-detachable GIS equipment monitoring sensor installation structure, referring to Figure 1-5The installation structure includes a structural body 1, an upper cover 6, a rear cover 4, a limit buckle 3 and a sensor 5, wherein: the front end of the structural body 1 is connected to the GIS equipment, and the interior of the structural body 1 is provided with a first channel 11, a second channel 12 and a third channel 13, the first channel 11, the second channel 12 and the third channel 13 are interconnected inside the structural body 1, the first channel 11 and the third channel 13 are parallel and located at the same height, the second channel 12 is located between the first channel 11 and the third channel 13 and is perpendicular to the first channel 11; a valve flap 2 is provided in the second channel 12, one end of the valve flap 2 is fixed to the inner wall of the second channel 12, and the valve flap 2 can rotate in the second channel 12 with the fixed position as the center under the action of a driving force, and when there is no external force Under the action of gravity, the valve disc 2 naturally droops, separating and connecting the first channel 11 and the third channel 13. The upper cover 6 covers the second channel 12. The rear cover 4 covers the rear end of the main body 1. The limit buckle 3 is located between the main body 1 and the rear cover 4, with its ends fixedly connected to the main body 1 and the rear cover 4, respectively. When the first channel 11 and the third channel 13 are connected, the first channel 11 and the third channel 13 form a passage for the sensor 5 to extend into the GIS. The sensor 5 then passes through the third channel 13 and the first channel 11 and extends into the GIS device. The insertion end of the sensor 5 is equipped with a limit slot 54, which cooperates with the limit buckle 3 to accurately limit the position of the sensor 5 inside the GIS device. This installation structure only requires a single limit slot, and the sensor 5 can be removed in a single operation, making it quick and easy to remove.

[0043] Due to the movement characteristics of the valve disc within the aforementioned mounting structure, the mounting structure must be installed parallel to the ground. During the installation of the GIS monitoring sensor, the mounting structure as a whole serves as a physical extension of the GIS equipment. Without affecting the physical properties of the GIS equipment, the three channels within the main structure 1, the valve disc 2, and the position-limiting buckle 3, in conjunction with the slot of the sensor 5, allow the sensor 5 to be inserted into the GIS for measurement without affecting GIS operation. Furthermore, if a sensor 5 malfunctions, it can be replaced without affecting GIS operation or requiring a power outage. Furthermore, the mounting structure of the present invention is self-sealing, enabling quick installation and replacement of the sensor 5.

[0044] In some embodiments, a mounting groove is provided on the inner wall of the second channel 12, and the end of the valve flap 2 close to the upper cover 6 is snap-fitted into the mounting groove. Specifically, a cylindrical structure matching the mounting groove is provided on the end of the valve flap 2 close to the upper cover 6, and the cylindrical structure is snap-fitted into the mounting groove, so that the valve flap 2 can rotate with the mounting groove as the central axis.

[0045] In some embodiments, the limit buckle 3 includes: a first rack 32 and a second rack 33 arranged opposite to each other, a buckle knob 31, a first buckle 36 and a second buckle 37; wherein the buckle knob 31 is located between the first rack 32 and the second rack, and a gear is provided at the bottom of the buckle knob 31, and the gear is engaged with the first rack teeth 322 of the first rack 32 and the second rack teeth 332 of the second rack; Figure 3 and Figure 5 When the latch knob 31 is rotated clockwise, the first rack 32 and the second rack 33 separate. Depending on the degree of separation, the position-limiting latch 3 matches the slot on the sensor 5 differently. By rotating the latch knob 31 to different positions, the separation between the first rack 32 and the second rack 33 is limited, thereby limiting the position of the sensor 5 and ensuring the sensor 5 can be inserted or removed. A first latch 36 is located on the side of the first rack 32 away from the latch knob 31. The first latch 36 and the first rack 32 are fixedly connected and maintain the same motion trajectory. A first latch tooth 362 is provided on the surface of the first latch 36 that interacts with the sensor 5. A second latch 37 is located on the side of the second rack 33 away from the latch knob 31. The second latch 37 and the second rack 33 are fixedly connected and maintain the same motion trajectory. A second latch tooth 372 is provided on the surface of the second latch 37 that interacts with the sensor 5. The second latch tooth 372 cooperates with the first latch tooth 362 to engage the sensor 5.

[0046] In some embodiments, the first snap-fit ​​tooth 362 and the second snap-fit ​​tooth 372 are both provided with a preset inclination angle on the vertical surface close to the third channel 13 (the surface in contact with the sensor 5) to facilitate the insertion of the sensor 5; wherein the inclination angle is set according to the specific structural dimensions of the sensor 5.

[0047] In some embodiments, a first rack slot 321 is provided on the side of the first rack 32 away from the buckle knob 31; a first buckle upper tooth 361 is provided on the first buckle 36, which mates with the first rack slot 321; a second rack slot 331 is provided on the side of the second rack 33 away from the buckle knob 31; and a second buckle upper tooth 371 is provided on the second buckle 37, which mates with the second rack slot 331. A first support return spring 34 is provided on the first buckle 36, and a second support return spring 35 is provided on the second buckle 37. The first support return spring 34 and the second support return spring 35 are located between the limit buckle 3 and the outer wall of the structural body 1. Their function is to support the limit buckle 3 and ensure that the entire structure is in a closed state when the buckle knob 31 is not under force.

[0048] In some embodiments, both the structural body 1 and the back cover 4 are provided with slots for installing the limit buckle 3. Specifically, the limit buckle 3 is provided with a connecting portion, such as Figure 3 The lower ends of the first and second snap hooks 36 and 37 are provided with semicircular protrusions that match the slots. There are slots corresponding to the connecting parts on the structural body 1 and the back cover 4 for the position-limiting snap hook 3 to be installed, thereby fixing the two ends of the position-limiting snap hook 3 to the structural body 1 and the back cover 4 respectively.

[0049] In some embodiments, a first sealing ring groove is provided on the outer end face of the first channel 11 to ensure air tightness between the mounting structure and the GIS equipment; a second sealing ring groove is provided on the outer end face of the second channel 12 to ensure air tightness between the upper cover 6 and the structural body 1.

[0050] In some embodiments, the sensor 5 is provided with a first sealing groove 51, a second sealing groove 52, and a third sealing groove 53 in sequence for installing sealing rings. Since the rotational movement of the center valve disc 2 requires a large space, a triple sealing ring is provided to ensure that at least one or more sealing rings are active during the insertion and replacement of the sensor 5, thereby ensuring the airtightness of the air chamber. The structural body 1 is also provided with a pressure relief channel 14. The pressure relief channel 14 is located at the lower portion of the structural body 1 and is connected to the third channel 13. Since the first channel 11, the second channel 12, and the third channel 13 are interconnected, the first channel 11, the second channel 12, the third channel 13, and the pressure relief channel 14 are all interconnected within the structural body 1. The pressure relief channel 14 cooperates with the first sealing groove 51, the second sealing groove 52, and the third sealing groove 53 on the sensor 5, so that the pressure relief channel 14 becomes a channel for releasing internal pressure of the sensor 5 during the insertion and replacement process. Specifically, the order in which the three sealing grooves are aligned with the pressure relief passage 14 during sensor 5 insertion minimizes the introduction of external air during sensor 5 insertion or replacement, reducing the purity of the air inside the GIS. During operation, the first sealing groove 51 is located within the first passage 11, tightly fitting against the inner wall of the first passage 11 and providing a seal. The second sealing groove 52 is located within the second passage 12. Because the space in the second passage 12 is larger than the second sealing groove 52, it does not provide a seal during operation. The third sealing groove 53 is located within the third passage 13, tightly fitting against the inner wall of the third passage 13 and providing a seal. Thus, during operation, two sealing layers are in effect, ensuring the airtightness of the overall installation structure.

[0051] In addition, the other end surfaces of the four channels extend to the outer surface of the structural body 1 , and corresponding first interfaces, second interfaces, third interfaces and pressure relief ports are formed at different positions on the outer surface of the structural body 1 .

[0052] The quick-release GIS equipment monitoring sensor mounting structure described in the above embodiment features a passageway within the structural body 1 for the sensor 5 to extend into the GIS interior. A retaining slot is provided on the sensor 5, which, in conjunction with the retaining clip 3, precisely limits the position of the sensor 5. The self-sealing structure and the retaining slot allow the sensor 5 to be removed in a single operation, enabling rapid removal and facilitating installation and replacement. This invention allows the sensor 5 to be inserted into the GIS for measurement without disrupting GIS operation. Furthermore, in the event of a sensor 5 failure, the sensor 5 can be replaced without disrupting GIS operation or requiring a power outage.

[0053] Figure 6-9 The assembled mounting structure is shown, along with schematic diagrams of the sensor 5's position during operation and replacement. The front end of the mounting structure is connected to the GIS device where the sensor is to be installed. Valve flap 2 is closed, separating the first channel 11 from the third channel 13, ensuring the normal operation of the GIS device.

[0054] When the sensor 5 is installed, the sensor 5 is aligned with the third channel 13. Figure 6 As shown, the sensor 5 is inserted into the third channel 13, and the front end (insertion end) of the sensor 5 is about to touch the valve disc 2. At this time, the state is as follows: Figure 7 As shown, the sensor 5 continues to extend, and the valve disc 2 is lifted up by the sensor 5. At this time, the state is as follows Figure 8 As shown, when the limit slot 54 of the sensor 5 is combined with the limit buckle 3, the state is as follows Figure 9 As shown, the entire installation process of the sensor 5 is now completed and the sensor 5 is in operation as a whole.

[0055] Replacing the sensor is an automatic dynamic process. When the sensor 5 is replaced, Figure 9 In the state shown, the gate valve knob on the limit buckle 3 is rotated to the replacement position, the limit buckle 3 is separated from the limit slot 54, and the sensor 5 automatically withdraws backward under the action of the internal air pressure of the GIS equipment. Figure 8 This is a schematic diagram of the middle process until the valve disc 2 automatically closes. At this time, the state is as follows Figure 7 As shown, in a normally operating GIS device, the internal air chamber pressure is between 0.4 MPa and 0.6 MPa. Due to the internal pressure and gravity of the GIS air chamber, valve disc 2 automatically closes after sensor 5 is withdrawn. When sensor 5 withdraws to the rear end of limit buckle 3, limit buckle 3 automatically closes due to the reset spring, and the corresponding gate valve knob automatically returns to the operating position without manual operation. At this point, sensor 5 is withdrawn and the GIS device continues to operate, unaffected by sensor replacement. Repeat the sensor 5 installation steps to complete sensor 5 replacement.
