Description

Technical Field

[0001] The invention belongs to the field of GIS monitoring, and in particular relates to a GIS isolating switch action monitoring device. Background Art

[0002] Gas-insulated metal switchgear (GIS) is widely used in high-voltage substations due to its compact structure, small footprint, easy maintenance, safe and stable operation, and little impact from environmental changes. GIS is a closed device. When a fault occurs, the power outage is long and the impact range is large. The moving and static contacts of the circuit breaker, disconnector, and earthing switch are located in the metal shell, and their opening and closing states cannot be directly observed from the outside. During the switching operation of the primary electrical equipment, the operator must clearly judge the opening and closing position of the knife switch, whether the moving contact rod is aligned after closing, and whether the predetermined opening and closing action has been performed. If the above factors are misjudged, it is very easy to cause power grid and equipment accidents, and there are major safety hazards. In recent years, there have been many accidents caused by the knife switch not opening and closing properly in various accident reports of the power system. It can be seen that this is an issue that cannot be ignored.

[0003] Under the premise that GIS is not working, these factors can be simply and accurately judged by visual observation or data collection of opening and closing related parameters. However, when the GIS is operating, there is a high-intensity electric field inside, and ordinary data collection devices operate with weak current, which makes it impossible to send signals accurately and effectively inside the GIS. Therefore, how to monitor the status of the internal disconnector of the GIS after operation is an urgent problem that needs to be solved. Summary of the invention

[0004] In view of the deficiencies of the prior art, the present invention provides a GIS isolating switch action monitoring device, which can monitor the action of the GIS isolating switch simply and accurately through a common data acquisition device.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A GIS isolating switch action monitoring device is arranged on a predetermined flange opening of a GIS shell, and the area where the isolating switch fracture is located inside the GIS shell is used as the monitoring area. The flange opening forms a flange channel that is open toward the inside of the GIS and toward the monitoring area, and the extension direction of the flange channel is used as the monitoring direction. The device is characterized in that it includes: an organic glass sheet, which is shielded and arranged on the flange channel. The organic glass sheet has a perspective entity and a heat collection channel, and the heat collection channel is open toward the inside of the GIS shell along the monitoring direction; an infrared glass sheet, which is shielded and arranged on the heat collection channel; an infrared light sensor, which is located outside the GIS shell and is connected to the monitoring terminal signal, and the infrared light sensor collects data on the heat distribution of the monitoring area through the infrared glass sheet; a monitoring light source and a monitoring camera, which are both located outside the GIS shell, and the monitoring camera is connected to the monitoring terminal signal. The monitoring light source illuminates the monitoring area through the perspective entity; and the monitoring camera collects images of the monitoring area through the perspective entity.

[0007] Preferably, the present invention also includes a capacitive tester, which is connected to the monitoring terminal signal. The capacitive tester has a voltage collection end, which is used to collect the voltage between the conductor inside the GIS shell and the GIS shell. The organic glass sheet also has a voltage monitoring channel, which is open toward the inside of the GIS shell along the monitoring direction. The capacitive tester is correspondingly inserted into the voltage detection channel, and the voltage collection end extends into the interior of the GIS shell.

[0008] Furthermore, the present invention also includes a pressing plate, which is located outside the GIS shell, and the pressing plate is fixed on the flange entity of the predetermined flange opening. The pressing plate is used to press the infrared glass sheet onto the organic glass sheet, and to press the organic glass sheet onto the predetermined flange opening. The pressing plate is also formed with multiple accommodating positions, and the multiple accommodating positions are used to correspondingly accommodate infrared light sensors, monitoring light sources, monitoring cameras and capacitive testers.

[0009] Furthermore, the accommodation position is a through hole, and the capacitive electroscope and the voltage monitoring channel are sealed by a sealing ring.

[0010] Furthermore, the present invention also includes a device cover, which is hingedly arranged on the pressing plate and is used to physically isolate the monitoring light source, the monitoring camera and the capacitive electroscope from the outside.

[0011] Furthermore, the flange channel has a first shielding step surface, the organic glass sheet is placed on the first shielding step surface, and the pressing plate has a top boss that fits into the flange channel, the top boss abuts against the edge of the organic glass sheet, the heat collection channel has a second shielding step surface, and the infrared glass sheet is placed on the second shielding step surface.

[0012] Furthermore, the flange channel, the organic glass sheet, the heat collection channel and the infrared glass sheet are sealed by a sealing ring, and the pressing plate, the organic glass sheet and the infrared glass sheet are sealed by a sealing ring.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. Because the GIS disconnector action monitoring device of the present invention includes an organic glass sheet, an infrared glass sheet, an infrared light sensor, a monitoring light source and a monitoring camera, the organic glass sheet is shielded and arranged on the flange channel, and has a perspective entity and a heat collection channel, the infrared glass sheet is shielded and arranged on the heat collection channel, and is connected to the monitoring terminal signal, the monitoring camera is connected to the monitoring terminal signal, and the monitoring light source illuminates the monitoring area through the perspective entity; the monitoring camera collects images of the monitoring area through the perspective entity, and since the knife switch opening and closing position, the stop position, whether the moving contact rod is aligned after closing, and whether the predetermined opening and closing action has been performed that need to be judged do not meet the predetermined requirements, in addition to being reflected in the spatial position of the moving contact rod, it will also be reflected in the thermal field distribution in the GIS shell. Therefore, the present invention collects the spatial position data of the moving contact rod and the thermal field distribution data in the GIS shell, thereby comprehensively judging the factors that need to be judged from two aspects, that is, the action of the GIS disconnector can be simply and accurately monitored through an ordinary data acquisition device.

[0015] 2. Because the present invention also includes a capacitive tester, which is connected to the monitoring terminal signal, the capacitive tester has a voltage collection end, and the capacitive tester is used to collect the voltage between the inner conductor of the GIS shell and the GIS shell. The organic glass sheet also has a voltage monitoring channel, and the voltage monitoring channel is open toward the inside of the GIS shell along the monitoring direction. The capacitive tester is correspondingly inserted in the voltage detection channel, and the voltage collection end extends into the interior of the GIS shell. Therefore, the present invention can verify whether the closing operation of the isolating switch is reliably completed and prevent the isolating switch from being grounded with electricity by collecting the voltage between the inner conductor of the GIS shell and the GIS shell through the capacitive tester.

[0016] 3. Because the present invention also includes a pressing plate, the pressing plate is fixed on the flange entity of the predetermined flange opening, the pressing plate is used to press the infrared glass sheet onto the organic glass sheet, and is used to press the organic glass sheet onto the predetermined flange opening, and the pressing plate is also formed with a plurality of accommodating positions, and the plurality of accommodating positions are used to correspondingly accommodate infrared light sensors, monitoring light sources, monitoring cameras and capacitive electroscopes. Therefore, the present invention reliably fixes the organic glass sheet, infrared glass sheet, infrared light sensor, monitoring light source, monitoring camera and capacitive electroscope through the pressing plate, thereby avoiding interference of component vibration on the collected data, making the collected data more accurate.

[0017] 4. Because the flange channel of the present invention has a first shielding step surface, the organic glass sheet is placed on the first shielding step surface, and the pressing plate has a top boss that fits into the flange channel, the top boss abuts against the edge of the organic glass sheet, the heat collection channel has a second shielding step surface, and the infrared glass sheet is placed on the second shielding step surface, therefore, the present invention adds freedom constraints through the step surface related components, so that the components can be better fixed and positioned.

[0018] 5. Because the flange channel, organic glass sheet, heat collection channel and infrared glass sheet of the present invention are sealed by sealing rings, and the pressing plate, organic glass sheet and infrared glass sheet are sealed by sealing rings, the present invention prevents leakage of insulating gas in the GIS shell through sealing, so that the insulation performance of the GIS will not decrease during the predetermined monitoring period.

DETAILED DESCRIPTION

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the following embodiments and drawings specifically illustrate the GIS disconnector action monitoring device of the present invention. It should be noted that the description of these implementation methods is used to help understand the present invention, but does not constitute a limitation of the present invention.

[0025] like Figure 1 As shown, the GIS disconnector action monitoring device 100 in this embodiment is arranged on a predetermined flange opening S1 of the GIS shell S, and the area where the disconnector break inside the GIS shell S is located is used as the monitoring area S3. The flange opening S1 forms a flange channel S2 which is open to the inside of the GIS shell S and faces the monitoring area S3. The extension direction of the flange channel S2 is used as the monitoring direction D, and the flange channel S2 has a first shielding step surface S21 protruding toward the inside of itself.

[0026] like Figure 2 As shown, the GIS disconnector action monitoring device 100 includes a plexiglass sheet 1, an infrared glass sheet 2, an infrared light sensor 3, a capacitive tester 4, a monitoring light source (not shown in the figure), a monitoring camera 5, a pressing plate 6, a device cover 7 and a sealing ring group.

[0027] The organic glass sheet 1 is laid on the first shielding step surface S21 through its own edge, so that the organic glass sheet 1 is shielded on the flange channel S2. The organic glass sheet 1 forms a heat collection channel 11, a perspective entity 12 and a voltage monitoring channel 13, and the heat collection channel 11 and the voltage monitoring channel 13 are both open toward the inside of the GIS shell S along the monitoring direction D. Specifically, the heat collection channel 11 and the voltage monitoring channel 13 are two through holes on the organic glass sheet 1, and the remaining entity parts form the perspective entity 12. In this embodiment, the heat collection channel 11 is located in the middle of the organic glass sheet 1.

[0028] The heat collection channel 11 has a second shielding step surface 11 a , and the second shielding step surface 11 a protrudes toward the inside of the heat collection channel 11 .

The monitoring light source illuminates the monitoring area S2 through the perspective entity 12. The monitoring camera 5 collects images of the monitoring area S2 through the perspective entity. Specifically, the monitoring camera 5 transmits the collected image data to the monitoring terminal, and the operator can obtain the spatial position information of the moving contact rod after the opening and closing action through the data, so as to facilitate the judgment of the opening and closing position of the knife switch, the stop position of the moving contact rod after closing, and whether the predetermined opening and closing action has been performed. Sometimes, this position information is not easy to judge. At this time, a comprehensive judgment is made through the thermal field distribution information.

[0033] The pressing plate 6 is located outside the GIS shell S. The pressing plate 6 is fixed on the flange entity of the predetermined flange opening S1. The pressing plate 6 is used to press the infrared glass sheet 2 onto the second shielding step surface 11a of the organic glass sheet 1, and is used to press the organic glass sheet 1 onto the first shielding step surface S21 of the predetermined flange opening S1. In this embodiment, the pressing plate 6 is detachably set on the flange entity by multiple screws on the edge.

[0035] The accommodating positions 61 are through holes, and the plurality of accommodating positions 61 are used to correspondingly accommodate the infrared light sensor 3, the monitoring light source, the monitoring camera 5 and the capacitive electroscope 4. Specifically, the infrared light sensor 3, the monitoring light source, the monitoring camera 5 and the capacitive electroscope 4 are inserted and positioned through the accommodating positions 61. In the present embodiment, the number of accommodating positions 61 is 5, and they have a variety of specifications or shapes.

[0036] The abutting boss 62 is inserted into the flange channel S2 , and the abutting boss 62 abuts against the edge of the organic glass sheet 1 . Specifically, the abutting boss 62 also abuts against the infrared glass sheet 2 .

[0037] The device cover 7 is hingedly disposed on the pressing plate 6 to physically isolate the monitoring light source, the monitoring camera 5 and the capacitive electroscope 4 from the outside. Specifically, the device cover 7 can be flipped open relative to the pressing plate 6 .

[0038] The sealing ring assembly includes a first sealing ring 81 , a second sealing ring 82 and a third sealing ring 83 .

[0039] The flange channel S2, the organic glass sheet 1, the heat collection channel 11, and the infrared glass sheet 2 are sealed by a sealing ring; the pressing plate 6, the organic glass sheet 1, and the infrared glass sheet 2 are sealed by a sealing ring; the capacitive electroscope 4 and the voltage monitoring channel 13 are sealed by a sealing ring, specifically, the organic glass sheet 1 and the pressing plate 6 and the first shielding step surface S21 are all sealed by a first sealing ring 81; the infrared glass sheet 2 and the pressing plate 6 and the second shielding step surface 11a are all sealed by a second sealing ring 82; the capacitive electroscope 4 and the voltage monitoring channel 13 are sealed by a second sealing ring 83.

[0040] The above-mentioned implementation modes are preferred cases of the present invention and are not used to limit the protection scope of the present invention. Various deformations or modifications that can be made by ordinary technicians in this field without creative work within the scope of the attached claims are still within the protection scope of this patent.
