Description

[0002] GIS (Gas Insulated Switchgear) is the English abbreviation of gas insulated switchgear, which has the advantages of compact structure, reliable operation, and no interference from the outside environment, so it is widely used in various substations of the national power system. When designing a substation, GIS design needs to be completed according to the electrical main wiring and scheme layout of the power design institute. The phase sequence ABC of the main transformer and the incoming and outgoing lines should correspond to the phase sequence of other connected devices outside.

With the above structure, the three-phase commutation function of the external bases 340 of the disc insulator can be satisfied.

[0049] like Figures 1 to 3 As shown, in some embodiments of the present invention, the housing 100 has a three-way structure. 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.

By rotating the positions of the second disc insulator 320 and the third disc insulator 330, the multiple commutation functions of the output end can be realized.

[0050] Specifically, such as Figure 4 , Figure 5 As shown, one end of each 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 housing 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 410.

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

[0052] As shown in the drawings, Figure 5 In some embodiments of the present application, the plug-in seat 420 is arranged on the disc insulator and connected to the external seat 340, the end of the connecting conductor 210 is provided with a connecting arm 211, and the plug-in head 410 is arranged on the connecting arm 211, and the plug-in head 410 is extended to the position corresponding to the external seat 340 through the connecting arm 211.

[0053] Specifically, as shown in the drawings, Figures 6 to 9 The three connecting conductors 210 extend to the middle part 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. 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 for mounting the plug-in head 410. By configuring the connecting arm 211 with a set length and a set angle, the three plug-in heads 410 are distributed in a regular triangle, and the three plug-in seats 420 are mounted on the inner side of the disc insulator and distributed (regular triangle) corresponding to the three plug-in heads 410, so that when the disc insulator is rotated, the plug-in head 410 can be matched with different plug-in seats 420, and the phase change function is realized.

[0054] As shown in the drawings, Figure 10 In some embodiments of the present application, the GIS combined electric appliance further includes a grounding switch assembly, which includes a connecting seat 510 and a grounding switch connecting mechanism 520 arranged on the connecting seat 510. The grounding switch connecting mechanism 520 is arranged corresponding to the connecting conductor 210, the connecting seat 510 is mounted to the external through hole, and the grounding switch connecting mechanism 520 is connected with the connecting conductor 210 through the plug-in structure, so as to realize the circuit inspection.

[0055] Specifically, the grounding switch connecting mechanism 520 is a maintenance grounding switch, and is provided with a handle driving mechanism for realizing the plug-in and separation of the plug-in structure, so as to achieve the function of the corresponding grounding switch.

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

[0057] As shown in the figure, Figure 11 In some embodiments of the present application, the plug-in seat 420 includes a seat body 421 made of elastic insulating material, the seat body 421 is provided with a plug-in cavity 422 corresponding to the plug-in head 410, the plug-in cavity 422 is provided with a conductive terminal 425 corresponding to the plug-in head 410, the seat body 421 is provided with a one-way valve capable of discharging gas in the plug-in cavity 422 to the outside, through the one-way valve, when the plug-in head 410 moves outward from the plug-in cavity 422, a negative pressure is formed in the plug-in cavity 422, thereby generating resistance to the outward movement of the plug-in head 410, reducing the separation of the conductive terminal 425 and the plug-in head 410 caused by external vibration, and improving the reliability of 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, so that the plug-in head 410 and the seat body 421 are stably plug-in matched.

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

[0060] Specifically, the seat body 421 is made of elastic material, when the internal gas is discharged through the tapered hole 424, the internal gas can open the outside opening of the tapered hole 424, thereby realizing the gas discharge, when a negative pressure is formed in the plug-in cavity 422 (the plug-in head 410 has a tendency to move outward), the pressure of the external gas acts on the outside opening of the tapered hole 424, so that the outside opening of the tapered hole 424 is closed, thereby realizing the blocking function.

[0061] Of course, in the actual implementation process, the one-way valve can also be a diaphragm pressure valve, a spring one-way valve, etc. For example, a through hole communicating with the outside is arranged on the seat body 421, and an elastic diaphragm is arranged at the opening of the through hole on the outside. The elastic diaphragm can block the entry of external gas into the through hole, and when internal gas is output through the through hole, the elastic diaphragm can be pushed open, thereby realizing the function of one-way exhaust and reverse blocking.

[0062] As shown in Figure 11 some embodiments of the present application, the seat body 421 is provided with a gas 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 gas 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 gas guide hole 423, so that after the installation mechanism of the disc insulator is disassembled, the staff can open the gas 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 combined electrical apparatus can maintain stable and reliable connection between the seat body 421 and the plug connector 410 under common vibration (small vibration amplitude), and can normally separate the seat body 421 and the plug connector 410 under large one-way pulling force.

[0064] In some embodiments of the present application, the gas guide hole 423 is arranged 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 gas guide hole 423. When the disc insulator moves outward relative to its installation position by a certain distance, 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 cavity 422 can be communicated to the outside through the gas 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 of the plug cavity 422, so that the plug connector 410 can be normally pulled out of the plug cavity 422.

[0065] Specifically, the middle part of the bottom of the seat body 421 is connected (threadedly connected) to the disc insulator through a conductive terminal 425. The gas guide hole 423 is located on the outside of the conductive terminal 425. When the conductive terminal 425 is fastened, the bottom of the seat body 421 can be compressed, so that the external opening of the gas guide hole 423 abuts against the inside surface of the disc insulator to form a closed structure. When the disc insulator is manually pulled outward to move outward by a certain distance, the bottom of the seat body 421 and the installation surface of the disc insulator can be separated to form a gap, thereby opening the outlet of the gas guide hole 423.

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

Figure 12

[0069] As shown in the figure, in some embodiments of the present application, the clamping structure comprises a spring 426 sleeved outside the seat body 421, the inner diameter of the plug-in cavity 422 is smaller than the outer diameter of the plug-in head 410, when the plug-in head 410 is inserted into the plug-in cavity 422, the inner wall of the plug-in cavity 422 can clamping the plug-in head 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 head 410. Figure 12

[0070] As shown in the figure, in some embodiments of the present application, the plug-in seat 420 further comprises a base 427, the plug-in cavity 422 penetrates through the seat body 421, one end of the plug-in cavity 422 can be sleeved outside the base 427, and the inner wall of the plug-in cavity 422 can clamping the base 427 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.
