Description

Technical Field

[0001] The present invention relates to the technical field of power switchgear, in particular to a GIS combined electrical appliance. Background Art

[0002] GIS (Gas Insulated Switchgear) is the abbreviation for gas-insulated, fully enclosed switchgear. Its advantages include compact structure, reliable operation, and immunity to external interference. Therefore, it is widely used in various substations across the national power system. During substation engineering design, the GIS design must be completed based on the main electrical wiring and layout diagrams provided by the power design institute. The phase sequence ABC of the main transformer and incoming and outgoing lines must correspond to that of other external connected equipment. Any change in the phase sequence of the incoming and outgoing lines requires the entire GIS to be replaced, which is inconvenient, costly, and has low versatility.

[0003] Furthermore, a maintenance grounding switch is often required for incoming line inspections of the main electrical wiring. If a three-position switch is not available, the maintenance grounding switch must be connected to the busbar. Traditional commutation busbars are long, and the conductors inside the tank are mostly shaped conductors, which restrict the space available for twisting. Furthermore, a transition conductor is required to connect to the basin insulator, making the processing and alignment of the shaped conductors difficult. This increases overall costs and reduces versatility. Summary of the Invention

[0039] Reference below Figures 1 to 12 A GIS combined electrical appliance according to an embodiment of the present invention is described.

[0040] like Figures 1 to 5As shown, according to an embodiment of the present invention, a GIS switchgear includes a housing 100, at least one disc insulator, and a conductor assembly 200. The housing 100 is provided with an external through-hole. The disc insulator is detachably mounted to the external through-hole via an insulator mounting mechanism. The disc insulator is provided with at least two external sockets 340. The conductor assembly 200 is disposed within the housing 100. The conductor assembly 200 includes connecting conductors 210 configured in a one-to-one correspondence with the external sockets 340. When the disc insulator is mounted to the external through-hole, the connecting conductors 210 and the external sockets 340 are connected via a plug-in structure to achieve a stable conductive connection. The disc insulator can be rotated to at least two set angles and detachably mounted to the external through-hole via the insulator mounting mechanism, so that the external sockets 340 can be plugged into different connecting conductors 210, thereby achieving a variety of different connection combinations and thus realizing a phase-changing function.

[0041] like Figure 4 、 Figure 5 As shown, in some embodiments of the present invention, the GIS combination electrical appliance is a three-phase combination electrical appliance, and the conductor assembly 200 includes three connecting conductors 210, thereby realizing the phase switching function of the three-phase electricity.

[0042] In some embodiments of the present invention, the disc insulator can be rotated to three set angles and detachably mounted to the external through hole through the insulator mounting mechanism, thereby realizing the phase commutation function of three-phase electricity.

[0043] Specifically, such as Figures 5 to 9 As shown, the disc insulator is provided with three external seats 340, which are distributed at the vertices of an equilateral triangle. The connecting conductor 210 has a connection end corresponding to the position of the external seats 340, so that when the disc insulator is rotated at an angle of 0° (360°), 120°, and 240°, its external seats 340 and the connecting conductor 210 have different connection phase sequences, thereby realizing the phase switching function.

[0044] It can be understood that in some embodiments of the present invention, under set usage scenarios, the GIS combination electrical appliance can be a two-phase or three-phase or more connector, and the external socket 340 on the disc insulator is configured according to the needs of the phase sequence, which is not described in detail here.

[0045] In some embodiments of the present invention, the disc insulator can be rotated along a set axis and can be removably mounted to an external through-hole through an insulator mounting mechanism. The external seat 340 is circumferentially spaced and evenly distributed along the set axis. When the phase sequence needs to be adjusted, the insulator mounting mechanism is released and the disc insulator is rotated to the set angle. After the disc insulator is installed and tightened, the phase change work can be completed.

[0046] like Figure 2As shown, in some embodiments of the present invention, the insulator mounting mechanism is a flange mounting mechanism, that is, corresponding flange structures are respectively provided on the disc insulator and the outer edge of the external through hole, and a plurality of annular evenly spaced mounting holes are configured, and the disc insulator is fastened and installed by a bolt assembly. When the phase sequence needs to be adjusted, the bolts are removed, the disc insulator is taken out, rotated to the set angle, and then installed and locked to complete the phase change work.

[0047] Of course, in the specific implementation process, the insulator installation mechanism can also be a buckle mechanism, etc., which will not be described in detail here.

[0048] like Figures 2 to 9 As shown, in some embodiments of the present invention, the conductor assembly 200 includes three connecting conductors 210, and the disc insulator is provided with an external seat 340 corresponding to the three connecting conductors 210 one by one. The three external seats 340 are distributed at the vertices of an equilateral triangle, and the center of the equilateral triangle coincides with the set axis. The connecting conductor 210 is provided with a connection end corresponding to the position of the external seat 340. Through the above structure, the three-phase commutation function of the external seat 340 of the disc insulator can be met.

[0049] like Figures 1 to 3 As shown, in some embodiments of the present invention, the housing 100 is a three-way structure, and the housing 100 is provided with a first external through hole 101, a second external through hole 102 and a third external through hole 103. A first disc insulator 310 is installed at the first external through hole 101, and an external seat 340 connected to the connecting conductor 210 is provided at the first disc insulator 310. A second disc insulator 320 is installed at the second external through hole 102, and an external seat 340 connected to the connecting conductor 210 through a plug-in structure is provided at the second disc insulator 320. A third disc insulator 330 is installed at the third external through hole 103, and an external seat 340 connected to the connecting conductor 210 through a plug-in structure is provided at the third disc insulator 330. By rotating the positions of the second disc insulator 320 and the third disc insulator 330, the phase-changing function of multiple groups at the output end can be realized.

[0050] Specifically, such as Figure 4 、 Figure 5 As shown, one end of the three connecting conductors 210 is fixedly connected to the first disc insulator 310 and electrically connected to the external socket 340 on the first disc insulator 310. The three connecting conductors 210 extend to the middle of the shell 100 of the three-way structure, and are respectively provided with mounting structures corresponding to the second external through hole 102 and the third external through hole 103 to facilitate the installation of the plug connector 410.

[0051] In some embodiments of the present invention, the plug-in structure includes a plug connector 410 and a socket 420, one of which is connected to the external socket 340, and the other is connected to the connecting conductor 210 to ensure the connection effect between the connecting conductor 210 and the socket 420.

[0052] like Figure 5 As shown, in some embodiments of the present invention, the plug socket 420 is arranged on the disc insulator and connected to the external socket 340, a connecting arm 211 is installed at the end of the connecting conductor 210, and the plug connector 410 is arranged on the connecting arm 211, and the plug connector 410 is extended to a position corresponding to the external socket 340 through the connecting arm 211.

[0053] Specifically, such as Figures 6 to 9 As shown, the three connecting conductors 210 extend to the middle of the shell 100 of the three-way structure, and mounting structures corresponding to the second external through hole 102 and the third external through hole 103 are respectively provided. One end of the connecting arm 211 is connected to the connecting conductor 210 through the connecting column 212, and the other end of the connecting arm 211 extends in the radial direction and is used to install the plug connector 410. By configuring the connecting arm 211 with a set length and a set angle, the three plug connectors 410 are distributed in an equilateral triangle. The three sockets 420 are installed on the inner side of the disc insulator and are distributed (equilateral triangle) corresponding to the three plug connectors 410, so that when the disc insulator is rotated, the plug connector 410 can be plugged into and matched with different sockets 420 to achieve the phase change function.

[0054] like Figure 10 As shown, in some embodiments of the present invention, the GIS combination electrical apparatus further includes a grounding switch assembly, which includes a connecting base 510 and a grounding switch connecting mechanism 520 provided on the connecting base 510. The grounding switch connecting mechanism 520 is configured corresponding to the connecting conductor 210. The connecting base 510 is installed in the external through hole. The grounding switch connecting mechanism 520 is connected to the connecting conductor 210 through a plug-in structure, thereby realizing circuit inspection.

[0055] Specifically, the grounding switch connection mechanism 520 is a maintenance grounding switch and is equipped with a handle drive mechanism for realizing the connection and separation of the plug-in structure, thereby achieving the corresponding function of the grounding switch.

[0056] like Figure 10As shown, in some embodiments of the present invention, the housing 100 is a three-way structure, and the housing 100 is provided with a first external through hole 101, a second external through hole 102 and a third external through hole 103. The first external through hole 101 is installed with a first disc insulator 310, and the first disc insulator 310 is provided with an external seat 340 connected to the connecting conductor 210. The second external through hole 102 is installed with a second disc insulator 320, and the second disc insulator 320 is provided with an external seat 340 connected to the connecting conductor 210 through a plug-in structure. The third external through hole 103 is installed with a connecting seat 510, and the connecting seat 510 is configured with a grounding switch connecting mechanism 520. At this time, the phase sequence conversion can be achieved by adjusting the orientation of the second disc insulator 320 to achieve the set detection effect.

[0057] like Figure 11 As shown, in some embodiments of the present invention, the socket 420 includes a seat body 421 made of elastic insulating material, the seat body 421 is provided with a plug cavity 422 corresponding to the plug connector 410, and the plug cavity 422 is provided with a conductive terminal 425 corresponding to the plug connector 410. The seat body 421 is provided with a one-way valve for discharging gas in the plug cavity 422. Through the one-way valve, when the plug connector 410 moves outward from the plug cavity 422, a negative pressure is formed in the plug cavity 422, thereby generating resistance to the outward movement of the plug connector 410, reducing the occurrence of separation of the conductive terminal 425 from the plug connector 410 due to external vibration, and improving the reliability of the electrical connection.

[0058] Specifically, the one-way valve allows gas to be discharged from the plug-in cavity 422 , but blocks external gas from entering the plug-in cavity 422 , thereby ensuring stable plug-in fit between the plug connector 410 and the seat body 421 .

[0059] like Figure 11 As shown, in some embodiments of the present invention, the seat body 421 is provided with a tapered hole 424 that gradually narrows from the inside to the outside, and the side wall of the tapered hole 424 forms a one-way valve to achieve a one-way conduction function from the inside to the outside.

[0060] Specifically, the seat body 421 is made of elastic material. When the internal gas is discharged through the conical hole 424, the internal gas can expand the outer opening of the conical hole 424, thereby realizing the gas discharge. When a negative pressure is formed in the plug-in cavity 422 (the plug connector 410 tends to move outward), the pressure of the external gas acts on the outer opening of the conical hole 424, causing the outer opening of the conical hole 424 to close, thereby realizing the blocking function.

[0061] Of course, in the specific implementation process, the one-way valve can also be a diaphragm pressure valve, a spring one-way valve, etc., such as a through hole connected to the outside is set in the seat body 421, and an elastic diaphragm is set at the outer opening of the through hole. The elastic diaphragm can prevent external gas from entering the through hole, and the internal gas can break open the elastic diaphragm when it is output through the through hole, thereby realizing the function of one-way exhaust and reverse blocking.

[0062] like Figure 11 As shown, in some embodiments of the present invention, the seat body 421 is provided with an air guide hole 423 extending from the inside to the outside. When the seat body 421 is installed on the disc insulator, the disc insulator can block the outlet of the air guide hole 423. When the seat body 421 is stretched to a set distance by the disc insulator, the disc insulator opens the outlet of the air guide hole 423, so that after the installation mechanism of the disc insulator is disassembled, the staff can open the air guide hole 423 by pulling the disc insulator outward, so that the seat body 421 and the plug connector 410 can be smoothly separated.

[0063] Specifically, through the above structure, the GIS combination electrical appliance can maintain a stable and reliable connection between the base body 421 and the plug connector 410 under common vibration conditions (the vibration amplitude is not large), and can normally separate the base body 421 and the plug connector 410 when a large external force pulls in one direction.

[0064] In some embodiments of the present invention, the air guide hole 423 is provided at the bottom of the seat body 421. When the seat body 421 is installed on the disc insulator, the bottom of the seat body 421 is compressed to block the external opening of the air guide hole 423. When the disc insulator moves outward a certain distance relative to its installation position, the bottom of the seat body 421 and the installation surface of the disc insulator can be separated to form a gap, so that the plug-in cavity 422 can be connected to the outside through the air guide hole 423 and the gap between the bottom of the seat body 421 and the installation surface of the disc insulator, thereby eliminating the negative pressure in the plug-in cavity 422, so that the plug connector 410 can be normally pulled out of the plug-in cavity 422.

[0065] Specifically, the middle part of the bottom of the seat body 421 is connected (threaded) to the disc insulator through the conductive terminal 425, and the air guide hole 423 is located on the outside of the conductive terminal 425. When the conductive terminal 425 is tightened, it can compress the bottom of the seat body 421, so that the external opening of the air guide hole 423 abuts against the inner side surface of the disc insulator to form a closed structure. When the disc insulator is manually pulled outward to move a set distance, the bottom of the seat body 421 and the mounting surface of the disc insulator can be separated to form a gap, thereby opening the outlet of the air guide hole 423.

[0066] like Figure 10 As shown, in some embodiments of the present invention, the external seat 340 is embedded in the disc insulator, and the seat body 421 is fixedly installed on the disc insulator.

[0067] like Figure 10 and Figure 12 As shown, in some embodiments of the present invention, the plug-in structure includes a plug connector 410 and a socket 420, one of which is connected to the grounding switch connection mechanism 520, and the other is connected to the connecting conductor 210 to ensure the connection effect between the connecting conductor 210 and the grounding switch connection mechanism 520.

[0068] like Figure 12 As shown, in some embodiments of the present invention, the socket 420 includes a seat body 421 made of elastic insulating material, the seat body 421 is provided with a plug cavity 422 corresponding to the plug connector 410, and the plug cavity 422 is provided with a conductive terminal 425 corresponding to the plug connector 410. The seat body 421 is provided with a clamping structure that can clamp the plug connector 410 to reduce the occurrence of the plug connector 410 being separated from the seat body 421, thereby improving the reliability of the electrical connection.

[0069] like Figure 12 As shown, in some embodiments of the present invention, the clamping structure includes a spring 426 mounted on the outside of the seat body 421, and the inner diameter of the plug-in cavity 422 is smaller than the outer diameter of the plug-in connector 410. When the plug-in connector 410 is inserted into the plug-in cavity 422, the inner wall of the plug-in cavity 422 can clamp the plug-in connector 410 due to the elastic force generated by the deformation of the seat body 421 and the spring 426, thereby achieving the purpose of fixing the plug-in connector 410.

[0070] like Figure 12 As shown, in some embodiments of the present invention, the socket 420 also includes a base 427, the plug-in cavity 422 passes through the seat body 421, one end of the plug-in cavity 422 can be inserted into the outside of the base 427, and the inner wall of the plug-in cavity 422 can hold the base 427 tightly due to the elastic force generated by the deformation of the seat body 421 and the spring 426, thereby fixing the seat body 421 to the base 427.

[0071] like Figure 12 As shown, in some embodiments of the present invention, a limiting shell 428 is provided on the base 427, and the seat body 421 is located in the limiting shell 428. The limiting shell 428 is provided with a hole for inserting the plug 410 and limiting the outward movement of the seat body 421, thereby stably installing the seat body 421 on the base 427.

[0072] like Figure 12 As shown, in some embodiments of the present invention, a snap-in piece 430 is provided on the base 427 , and a slot for the snap-in piece 430 to be inserted into the inner wall of the insertion cavity 422 is provided, thereby stably mounting the base 421 on the base 427 .

[0073] like Figure 12As shown, in some embodiments of the present invention, the conductive terminal 425 is provided on the base 427, and the inner wall of the plug-in cavity 422 is provided with a conductor 429 in a ring-shaped and spaced manner. The conductor 429 is electrically connected to the base 427. When the plug connector 410 is inserted into the plug-in cavity 422, the inner side of the conductor 429 can abut against the plug connector 410, thereby forming an electrical connection. Even when the plug connector 410 is accidentally separated from the conductive terminal 425 (such as when subjected to vibration), the conductor 429 can still maintain connection with the plug connector 410, thereby improving the reliability of the electrical connection.

[0074] like Figure 12 As shown, in some embodiments of the present invention, the inner side surface of the conductor 429 is a slope, and the slope gradually tilts toward the center of the plug cavity 422 along the insertion direction of the plug connector 410, thereby gradually narrowing the profile of the inner cross-section of the plug cavity 422, so that when the plug connector 410 is inserted, the conductor 429 has a better abutment effect with the outer wall of the plug connector 410, thereby improving the reliability of the electrical connection.

[0075] like Figure 12 As shown, in some embodiments of the present invention, at least one coil of the spring 426 corresponds to the position of the conductor 429, so that the spring 426 can exert a larger elastic force on the conductor 429, thereby improving the abutment effect between the conductor 429 and the plug connector 410.

[0076] like Figure 10 and Figure 12 As shown, in some embodiments of the present invention, the plug connector 410 is installed on the grounding switch connection mechanism 520 , and the socket 420 is installed on the connecting conductor 210 .

[0077] Specifically, the base 427 is mounted on the connecting conductor 210 .

[0078] In the present invention, Figure 11 and Figure 12 Two different embodiments of the plug-in structure are respectively shown, both of which can meet the function of electrical connection and have high reliability and stability.

[0079] Of course, the invention is not limited to the above-mentioned embodiments. Those skilled in the art may make equivalent modifications or substitutions without violating the spirit of the invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
