[0001] The utility model relates to the technical field of electrical equipment, in particular to an online monitoring device for sulfur hexafluoride in a hydropower station GIS. Background Art

[0002] GIS (metal-enclosed gas-insulated switchgear) substations have a small footprint and strong corrosion resistance, and have become the first choice for new substations in the future. The amount of sulfur hexafluoride gas used in GIS substations is quite large, so for safety reasons, regular inspections and maintenance are required.

[0003] Patent publication number "CN215489143U" discloses "a sulfur hexafluoride environmental monitoring device based on a rapid response mechanism" which includes a shell body, monitoring mechanisms are installed on both sides of the inner center of the shell body, a gas replenishing mechanism is installed at the inner center of the shell body, mounting rings are installed on both sides of the bottom center of the shell body, a small controller is installed on the front of the shell body, connecting rods are installed on both sides of the shell body, and a solar panel is installed on the top of the connecting rod. By arranging the shell body and the monitoring mechanism, the problem of judging whether the sulfur hexafluoride gas is leaking by detecting the sulfur hexafluoride gas pressure in the equipment pipeline by a gas pressure sensor is solved. Since the sulfur hexafluoride gas will produce pressure changes due to changes in external temperature, the problem of erroneous detection results is solved.

[0004] In view of the above problems, although the equipment can realize the functions of detecting and replenishing sulfur hexafluoride, when inspecting, maintaining and servicing the equipment, how to prevent gas leakage when disassembling the detection device and various gas pipelines is a very important link, and this device does not have this function.

[0032] It should be noted that in the description of the embodiments of the present application, the terms "front, rear", "left, right", "up, down", etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present application. The terms "install", "connect", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be a connection between the two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0033] The present application is further described in detail below through drawings and examples.

[0034] Reference Figures 1 to 4 The embodiment of the present application provides a hydropower station GIS sulfur hexafluoride online monitoring device, wherein an auxiliary component 2 is arranged at the bottom of the sulfur hexafluoride detector 1, and a closing component 3 is arranged between the auxiliary components 2; the auxiliary component 2 includes a valve connecting pipe 21, the top of the valve connecting pipe 21 is fixedly connected to the bottom of the sulfur hexafluoride detector 1, and the bottom of the valve connecting pipe 21 is fixedly connected to an upper sealing cylinder 23.

[0035] A fixing clamp 22 is fixedly connected to the top of the upper sealing cylinder 23 .

[0036] A fixing rod 25 is fixedly connected to the inner wall of the upper sealing tube 23 .

[0037] The bottom of the lower sealed cylinder 24 is fixedly connected with an equipment connecting pipe 26 .

[0038] During specific operation: the sulfur hexafluoride gas in the electrical equipment passes through the equipment connecting pipe 26, passes through the closing component 3, and then reaches the sulfur hexafluoride detector 1 through the valve connecting pipe 21. Various data are measured to see if there is any leakage. The fixed clamp 22 is used to reinforce the valve connecting pipe 21 to prevent shaking from affecting the monitoring equipment.

[0039] Reference Figures 1 to 4 In one aspect of the present embodiment, the closing assembly 3 includes a swivel 31 , the top of the swivel 31 is rotatably connected to the bottom of the upper sealed cylinder 23 , and the bottom of the swivel 31 is rotatably connected to the lower sealed cylinder 24 .

[0040] A rotating shaft 32 is fixedly connected to the top of the rotating ring 31, an arc rod 33 is rotatably connected to the outer side of the rotating shaft 32, a blocking block 35 is rotatably connected to the bottom of one end of the arc rod 33, and a docking ring 34 is rotatably connected to one end of the top of the blocking block 35.

[0041] The top of the docking ring 34 is fixedly connected to one end of the fixing rod 25 .

[0042] One end of the valve connecting pipe 21 penetrates into the interior of the upper sealing cylinder 23 and is fixedly connected to the inner ring wall of the docking ring 34 .

[0043] During specific operation: the rotating ring 31 is rotated to drive the rotating shaft 32 on its top to move, and the outer side is rotatably connected with the arc rod 33. Because the arc rod 33 is rotatably connected to one end of the blocking block 35, and one end of the blocking block 35 is also rotatably connected to the bottom of the docking ring 34, when the rotating ring 31 rotates in one direction, the arc rod 33 will pull one end of the blocking block 35. The blocking block 35 will rotate around the point where it is rotatably connected to the bottom of the docking ring 34 under the tension, thereby achieving displacement to change its original position and realizing the opening of the closing component 3. Then the rotating ring 31 is rotated in the opposite direction, and the blocking block 35 will be closed by the same principle.

[0044] All electrical equipment in this solution are powered by an external power supply.

[0045] Working principle: The sulfur hexafluoride gas in the electrical equipment passes through the equipment connecting pipe 26, passes through the closing component 3, and then reaches the sulfur hexafluoride detector 1 through the valve connecting pipe 21. Various data are measured to see if there is any leakage. The fixing clamp 22 is used to reinforce the valve connecting pipe 21 to prevent shaking from affecting the monitoring equipment.

[0046] By rotating the swivel 31, the rotating shaft 32 on the top is displaced and the outer side is rotatably connected to the arc rod 33. Because the arc rod 33 is rotatably connected to one end of the blocking block 35, and one end of the blocking block 35 is also rotatably connected to the bottom of the docking ring 34, when the swivel 31 rotates in one direction, the arc rod 33 will pull one end of the blocking block 35. The blocking block 35 will rotate around the point where it is rotatably connected to the bottom of the docking ring 34 due to the tension, thereby achieving displacement to change its original position and realize the opening of the closing component 3. Then the swivel 31 is rotated in the opposite direction, and the blocking block 35 will be closed by the same principle.

[0047] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0048] Although the embodiments of the present application have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present application, and that the scope of the present application is defined by the appended claims and their equivalents.
