Description

Technical Field

[0001] The present application belongs to the technical field of power generation equipment, and in particular, relates to an electrical equipment component, a substation and an energy storage system. Background Art

[0002] In electrical equipment assemblies, some different electrical equipment need to be electrically connected through copper busbars, communication cables or other conductors, and a connection shield is set outside the conductor to protect the conductor. When installing electrical equipment and connection shields, one electrical equipment is usually installed on an integrated platform, and one end of the connection shield is connected to the electrical equipment. Another electrical equipment is then installed on the integrated platform, and the other end of the connection shield is connected to the electrical equipment. During the connection process, multiple workers are required to operate between the two electrical equipment. However, the distance between some electrical equipment is small, and it is difficult for workers to connect the connection shield and the electrical equipment between the two electrical equipment, resulting in reduced installation efficiency. Utility Model Content

[0003] The present application aims to solve at least one of the technical problems existing in the prior art. To this end, the present application proposes an electrical equipment assembly, a substation and an energy storage system, which can facilitate workers to install a connection protective cover when the distance between the first electrical equipment and the second electrical equipment is small, improve installation efficiency and reduce personnel costs.

[0004] In a first aspect, the present application provides an electrical device assembly, comprising:

[0005] a first electrical device having a first mounting hole;

[0006] a second electrical device, wherein the second electrical device has a second mounting hole, and the first electrical device and the second electrical device are electrically connected via a conductor;

[0007] A connecting protective cover, wherein the first end of the connecting protective cover is connected to the first electrical device, the second end of the connecting protective cover passes through the first mounting hole and is connected to the second electrical device at the second mounting hole, and the connecting protective cover is suitable for being covered outside the conductor.

[0008] According to the electrical equipment assembly provided in the embodiment of the present application, by respectively providing a first mounting hole and a second mounting hole on the first electrical equipment and the second electrical equipment, it is convenient for workers to install a connecting protective cover when the distance between the first electrical equipment and the second electrical equipment is small, thereby improving installation efficiency and reducing personnel costs.

[0009] According to one embodiment of the present application, the end of the second mounting hole facing away from the first electrical device is provided with a first flange bent inwardly, the second end of the connecting protective cover is provided with a second flange bent inwardly, and the first flange is connected to the second flange.

[0010] It can be understood that if the first flange is bent outward relative to the second mounting hole and the second flange is bent outward relative to the connecting protective cover, then when installing the connecting protective cover, the staff needs to operate in the gap between the outer wall of the connecting protective cover and the first mounting hole and the second mounting hole. The gap is small and inconvenient to operate. Therefore, by connecting the first flange bent inward relative to the second mounting hole with the second flange bent inward relative to the connecting protective cover, the staff's operating space can be increased, thereby facilitating the staff's movements and further improving the installation efficiency.

[0011] According to one embodiment of the present application, a first sealing member is provided between the first flange and the second flange.

[0012] By arranging the first sealing member between the first flange and the second flange, the sealing between the connection protection cover and the second electrical device can be improved, thereby improving the overall protection performance after the first electrical device and the second electrical device are connected.

[0013] According to an embodiment of the present application, the first end of the connecting protective cover is provided with a third flange bent outward, and the third flange is connected to the first electrical device.

[0014] The provision of the third flange can facilitate the connection between the protective cover and the first electrical device, while reducing the range of motion of the staff in the first electrical device and reducing the probability of inconvenience for the staff in operating when the space in the first electrical device is small.

[0015] According to an embodiment of the present application, a fourth flange bent outward is provided at one end of the first mounting hole away from the second electrical device, and the fourth flange is connected to the third flange.

[0016] Through the setting of the above-mentioned fourth flange, when the third flange is connected to the fourth flange, the inner wall surface of the first mounting hole can be fitted with the outer wall surface of the connecting protective cover. Since the thickness of the first mounting hole is greater than the thickness of the fourth flange, the contact area between the first mounting hole and the connecting protective cover can be increased, thereby improving the protective effect between the first mounting hole and the connecting protective cover.

[0017] According to one embodiment of the present application, a second sealing member is provided between the third flange and the fourth flange.

[0018] By arranging the second sealing member between the third flange and the fourth flange, the sealing between the connection protection cover and the first electrical device can be improved, thereby improving the overall protection performance after the first electrical device and the second electrical device are connected.

[0019] According to an embodiment of the present application, the first end of the connecting protective cover is connected to the first electrical device via a threaded connector and a rivet nut;

[0020] and / or,

[0021] The second end of the connecting protective cover is connected to the second electrical device via a threaded connector and a rivet nut.

[0022] Since the rivet nut has its own sealing performance after being connected with the threaded connector, by connecting the connecting protective cover with the first electrical device and the second electrical device through the threaded connector and the rivet nut, the sealing between the connecting protective cover and the first electrical device and the second electrical device can be improved while reducing the number of parts and components, thereby reducing production costs.

[0023] According to one embodiment of the present application, the connection protection cover includes:

[0024] A first connecting member, at least a portion of which is made of a flexible material;

[0025] a second connecting member, the second connecting member being mounted on a first end of the first connecting member, the second connecting member being connected to the first electrical device;

[0026] A third connecting member is installed at the second end of the first connecting member, and the third connecting member is connected to the second electrical device.

[0027] Through the arrangement of the above-mentioned first connecting member, second connecting member and third connecting member, the flexible deformation of the first connecting member can be used to compensate for the errors during the production and installation of the first electrical equipment and the second electrical equipment. At the same time, the first pressure strip, the second pressure strip, the second connecting member and the third connecting member are all rigid structural members, which can improve the connection stability and strength between the intermediate member and the second connecting member and the third connecting member, and improve the connection stability and strength between the first connecting member and the first electrical equipment and the second electrical equipment, further improving the protective performance of the connection protective cover.

[0028] According to an embodiment of the present application, a sealant is provided between the first end of the first connecting member and the second connecting member;

[0029] and / or,

[0030] A sealant is provided between the second end of the first connecting member and the third connecting member.

[0031] According to one embodiment of the present application, the size of the second connecting member is larger than the size of the third connecting member, and the size of the first end of the first connecting member is larger than the size of the second end.

[0032] In a second aspect, the present application provides a substation, the substation comprising:

[0033] Integrated platform;

[0034] The electrical equipment component as described in any of the above embodiments is installed on the integrated platform.

[0035] In a third aspect, the present application provides an energy storage system, the energy storage system comprising:

[0036] A substation as described in any of the above embodiments.

[0037] According to the energy storage system provided in the embodiment of the present application, by adopting the substation of any of the above embodiments, it is convenient for workers to install the connection protection cover when the distance between the first electrical equipment and the second electrical equipment is small, thereby improving installation efficiency and reducing personnel costs.

DETAILED DESCRIPTION

[0048] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0049] Reference below Figure 1-Figure 4 An electrical equipment assembly, a substation, and an energy storage system according to embodiments of the present application are described.

[0050] The present application embodiment provides an electrical device component, such as Figure 1-Figure 3 As shown, the electrical device assembly includes a first electrical device 100 , a second electrical device 200 and a connection protection cover 300 .

[0051] The electrical device assembly may further include an integrated platform, and the first electrical device 100 and the second electrical device 200 are suitable for being installed on the integrated platform.

[0052] The first electrical device 100 may be a medium voltage device, a low voltage device or other electrical devices, and the second electrical device 200 may be a medium voltage device, a low voltage device or other electrical devices. The first electrical device 100 and the second electrical device 200 are arranged to be spaced apart in the horizontal direction.

[0053] like Figure 1-Figure 3 As shown, the first electrical device 100 has a first mounting hole 110. The first mounting hole 110 may be a circular structure, a trapezoidal structure, or other shapes, such as Figure 1 As shown, the first mounting hole 110 is a rectangular structure, and the first mounting hole 110 is disposed on a side of the first electrical device 100 facing the second electrical device 200 .

[0054] like Figure 1-Figure 3 As shown, the second electrical device 200 has a second mounting hole 210. The second mounting hole 210 may be a circular structure, a trapezoidal structure, or other shapes. Figure 1As shown, the second mounting hole 210 is a rectangular structure, and the second mounting hole 210 is disposed on a side of the second electrical device 200 facing the first electrical device 100 .

[0055] The first electrical device 100 and the second electrical device 200 are electrically connected via a conductor. The first electrical device 100 and the second electrical device 200 may be electrically connected via a copper bus, a wire or other conductor, and the conductor is located in the gap between the first electrical device 100 and the second electrical device 200.

[0056] like Figure 1-Figure 3 As shown, the first end of the connecting protective cover 300 is connected to the first electrical device 100, and the first end of the connecting protective cover 300 is connected to the side of the first electrical device 100 facing the second electrical device 200. The first end of the connecting protective cover 300 can be connected to the first electrical device 100 by threaded connection, bonding, snap-on connection or other methods.

[0057] like Figure 1-Figure 3 As shown, the second end of the connection protective cover 300 passes through the first mounting hole 110 and is connected to the second electrical device 200 at the second mounting hole 210, and the connection protective cover 300 is suitable for being covered outside the conductor. The connection protective cover 300 is a hollow structure so that the connection protective cover 300 can pass from one end of the conductor to the other end.

[0058] like Figure 1-Figure 3 As shown, the second end of the connecting protective cover 300 is connected to the side of the second electrical device 200 facing the first electrical device 100, and the second end of the connecting protective cover 300 can be connected to the second electrical device 200 by threaded connection, bonding, snap connection or other connection methods.

[0059] In the actual implementation process, when installing the first electrical device 100 and the second electrical device 200, the first electrical device 100 and the second electrical device 200 are first installed on the integrated platform with a spacing in the horizontal direction, and the first electrical device 100 and the second electrical device 200 are electrically connected using a conductor. Then, the second end of the connecting protective cover 300 can be sleeved outside the conductor in the first electrical device 100, and then pass through the first mounting hole 110 and the second mounting hole 210 in sequence to connect with the second electrical device 200, and then the first end of the connecting protective cover 300 can be connected to the first electrical device 100.

[0060] By respectively providing the first mounting hole 110 and the second mounting hole 210 on the first electrical device 100 and the second electrical device 200, a worker can install the connection protection cover 300 between the first electrical device 100 and the second electrical device 200 inside the first electrical device 100, without having to perform installation operations in the gap between the first electrical device 100 and the second electrical device 200, and the number of workers can be reduced at the same time.

[0061] According to the electrical equipment assembly provided in the embodiment of the present application, by respectively setting the first mounting hole 110 and the second mounting hole 210 on the first electrical equipment 100 and the second electrical equipment 200, when installing the connecting protective cover 300 in a narrow space, part of the space in the first electrical equipment 100 can be used for installation, thereby facilitating the staff to install the connecting protective cover 300 when the distance between the first electrical equipment 100 and the second electrical equipment 200 is small, thereby improving installation efficiency and reducing personnel costs, and the second end of the connecting protective cover 300 passes through the first mounting hole 110 to improve the waterproof effect between the connecting protective cover 300 and the first electrical equipment 100.

[0062] In some embodiments, Figure 1-Figure 3 As shown, the end of the second mounting hole 210 away from the first electrical device 100 is provided with a first flange 220 bent inwardly, and the second end connected to the protective cover 300 is provided with a second flange 331 bent inwardly, and the first flange 220 is connected to the second flange 331.

[0063] Among them, Figure 1-Figure 3 As shown, the second mounting hole 210 is provided with a first flange 220 bent inwardly around one end away from the first electrical device 100 , and the second end connected to the protective cover 300 is provided with a second flange 331 bent inwardly around the second end.

[0064] The first flange 220 and the second flange 331 may be connected by thread connection, bonding, snap connection or other methods, such as Figure 1-Figure 3 As shown, the first flange 220 and the second flange 331 are both provided with threaded connectors spaced apart along the circumferential direction, and the first flange 220 and the second flange 331 are connected by the threaded connectors.

[0065] During the actual implementation process, when installing the connecting protective cover 300, the second end of the connecting protective cover 300 is passed through the first mounting hole 110 and the second mounting hole 210 in sequence inside the first electrical device 100. Since the connecting protective cover 300 is a hollow structure, and the first flange 220 and the second flange 331 are bent inward relative to the second mounting hole 210 and the connecting protective cover 300, respectively, the staff can insert their hands into the hollow part of the connecting protective cover 300, and connect the first flange 220 and the second flange 331 in the hollow part through a threaded connector to complete the connection between the second end of the connecting protective cover 300 and the second electrical device 200.

[0066] It can be understood that if the first flange 220 is bent outward relative to the second mounting hole 210, and the second flange 331 is bent outward relative to the connecting protective cover 300, then when installing the connecting protective cover 300, the staff needs to operate in the gap between the outer wall of the connecting protective cover 300 and the first mounting hole 110 and the second mounting hole 210. The gap is small and inconvenient to operate. Therefore, by utilizing the first flange 220 bent inward relative to the second mounting hole 210 and the second flange 331 bent inward relative to the connecting protective cover 300 to connect, the staff's operating space can be increased, thereby facilitating the staff's movements and further improving the installation efficiency.

[0067] In some embodiments, a first seal 221 is disposed between the first flange 220 and the second flange 331 .

[0068] The first seal 221 may include but is not limited to a rubber gasket, an asbestos-free fiber rubber gasket, a flexible graphite metal composite gasket or other types of first seals 221. For example, the first seal 221 is an EPDM (EthylenePropylene Diene Monomer) rubber strip sealing gasket.

[0069] By providing the first seal 221 between the first flange 220 and the second flange 331 , the sealing between the connection protection cover 300 and the second electrical device 200 can be improved, thereby improving the overall protection performance after the first electrical device 100 and the second electrical device 200 are connected.

[0070] In some embodiments, Figure 1-Figure 3 As shown, the first end of the connecting protective cover 300 is provided with a third flange 321 bent outward, and the third flange 321 is connected to the first electrical device 100 .

[0071] Among them, the first end of the connecting protective cover 300 is provided with a third flange 321 bent outwardly around the periphery, and the third flange 321 and the first electrical device 100 can be connected by thread connection, bonding, snap connection or other methods, for example, Figure 1-Figure 3 As shown, the third flange 321 and the first electrical device 100 are both provided with threaded connectors spaced apart along the circumferential direction, and the third flange 321 and the first electrical device 100 are connected via the threaded connectors.

[0072] like Figure 1-Figure 3 As shown, the third flange 321 can be arranged parallel to the vertical direction, that is, the end face of the third flange 321 is arranged toward the door body of the first electrical device 100, and the third flange 321 can also have a certain angle with the vertical direction.

[0073] In the actual implementation process, Figure 1-Figure 3 As shown, when the protective cover 300 is installed and connected, the third flange 321 is fitted together with the first electrical device 100. Since the end face of the third flange 321 faces the door body of the first electrical device 100, when the staff enters the first electrical device 100, the third flange 321 faces the staff. At this time, the staff can connect the third flange 321 to the first electrical device 100.

[0074] The provision of the third flange 321 can facilitate the connection between the protective cover 300 and the first electrical device 100, and can also reduce the range of motion of the staff in the first electrical device 100, thereby reducing the probability of inconvenience for the staff in operating when the space in the first electrical device 100 is small.

[0075] In some embodiments, Figure 1-Figure 3 As shown, a fourth flange 120 bent outward is provided at one end of the first mounting hole 110 away from the second electrical device 200 , and the fourth flange 120 is connected to the third flange 321 .

[0076] Among them, Figure 1-Figure 3 As shown, the end of the first mounting hole 110 away from the second electrical device 200 is provided with a fourth flange 120 bent outward all around, the fourth flange 120 is arranged parallel to the third flange 321, and the fourth flange 120 is provided with a plurality of threaded connectors spaced apart along the circumferential direction.

[0077] In actual implementation, when the protective cover 300 is installed and connected, the third flange 321 is fitted with the fourth flange 120 , and the third flange 321 and the fourth flange 120 are connected by threaded connectors thereon.

[0078] It can be understood that if the fourth flange 120 is bent inward relative to the first mounting hole 110, the gap between the first mounting hole 110 and the connecting protective cover 300 is protected by the fitting arrangement of the third flange 321 and the fourth flange 120, but the thickness of the fourth flange 120 is relatively small, that is, the contact area between the fourth flange 120 and the connecting protective cover 300 is relatively small, so the protection effect is not good, and dust or other external impurities can enter the interior from between the fourth flange 120 and the outer wall of the connecting protective cover 300, resulting in affecting the conductor or the electronic components inside the first electrical device 100 and the second electrical device 200.

[0079] By setting the above-mentioned fourth flange 120, when the third flange 321 is connected to the fourth flange 120, the inner wall surface of the first mounting hole 110 can be fitted with the outer wall surface of the connecting protective cover 300. Since the thickness of the first mounting hole 110 is greater than the thickness of the fourth flange 120, the contact area between the first mounting hole 110 and the connecting protective cover 300 can be increased, thereby improving the protective effect between the first mounting hole 110 and the connecting protective cover 300.

[0080] In some embodiments, a second sealing member 121 is disposed between the third flange 321 and the fourth flange 120 .

[0081] The second seal 121 may include but is not limited to a rubber gasket, an asbestos-free fiber rubber gasket, a flexible graphite metal composite gasket or other types of second seals 121. For example, the second seal 121 is an EPDM (EthylenePropylene Diene Monomer) rubber strip sealing gasket.

[0082] By providing the second sealing member 121 between the third flange 321 and the fourth flange 120 , the sealing between the connection protection cover 300 and the first electrical device 100 can be improved, thereby improving the overall protection performance of the first electrical device 100 and the second electrical device 200 after being connected.

[0083] In some embodiments, Figure 1-Figure 3 As shown, the first end of the connecting protective cover 300 is connected to the first electrical device 100 via a threaded connector and a rivet nut; and / or, the second end of the connecting protective cover 300 is connected to the second electrical device 200 via a threaded connector and a rivet nut.

[0084] Among them, Figure 1-Figure 3 As shown, the first end of the connecting protective cover 300 is connected to the first electrical device 100 via a threaded connector and a rivet nut, and the second end of the connecting protective cover 300 is connected to the second electrical device 200 via a threaded connector and a rivet nut.

[0085] One of the third flange 321 connecting the first end of the protective cover 300 and the fourth flange 120 of the first electrical device 100 is provided with a first fastening screw 322, and the other of the third flange 321 connecting the first end of the protective cover 300 and the fourth flange 120 of the first electrical device 100 is provided with a first rivet nut 130, for example, Figure 1-Figure 3 As shown, a first fastening screw 322 is disposed on the third flange 321 , and a first rivet nut 130 is disposed on the fourth flange 120 .

[0086] A second fastening nut is provided in one of the second flange 331 connecting the second end of the protective cover 300 and the first flange 220 of the second electrical device 200, and a second rivet nut 230 is provided in the other of the second flange 331 connecting the second end of the protective cover 300 and the first flange 220 of the second electrical device 200, for example. Figure 1-Figure 3 As shown, a second fastening screw 332 is provided on the second flange 331 , and a second rivet nut 230 is provided on the first flange 220 .

[0087] Since the rivet nut has its own sealing performance after being connected with the threaded connector, by connecting the connecting protective cover 300 with the first electrical device 100 and the second electrical device 200 through the threaded connector and the rivet nut, the sealing between the connecting protective cover 300 and the first electrical device 100 and the second electrical device 200 can be improved while reducing the number of parts and reducing production costs.

[0088] In some embodiments, Figure 4 As shown, the connection protection cover 300 includes a first connection member 310 , a second connection member 320 and a third connection member 330 .

[0089] Among them, Figure 4 As shown, the first connecting member 310 includes a middle member 313, a first pressure strip 311 and a second pressure strip 312. The middle member 313 is a flexible material member, and the middle member 313 can be made of, including but not limited to, silicon titanium canvas, rubber sandwich cloth or other flexible materials.

[0090] like Figure 4 As shown, the first pressure strip 311 is installed on the outer periphery of the first end of the middle piece 313, and the second pressure strip 312 is installed on the outer periphery of the second end of the middle piece 313. Both the first pressure strip 311 and the second pressure strip 312 can be sheet metal structural parts or other rigid structural parts.

[0091] like Figure 4 As shown, the first pressure strip 311 can be connected to the periphery of the first end of the middle piece 313 by bonding or other means, and the second connecting piece 320 can be connected to the periphery of the second rigid section of the middle piece 313 by bonding or other means.

[0092] like Figure 4 As shown, the second connecting member 320 is installed at the first end of the first connecting member 310, and the second connecting member 320 is connected to the first electrical device 100; the third connecting member 330 is installed at the second end of the first connecting member 310, and the third connecting member 330 is connected to the second electrical device 200. The second connecting member 320 and the third connecting member 330 can both be sheet metal structural members or other rigid structural members.

[0093] One of the first pressure strip 311 and the second connecting member 320 is provided with a third fastening screw 314, and the other of the first pressure strip 311 and the second connecting member 320 is provided with a third pressure rivet nut, for example, Figure 4 As shown, the first pressure strip 311 is provided with a plurality of third fastening screws 314 distributed at intervals, and the second connecting member 320 is provided with a plurality of third rivet nuts distributed at intervals.

[0094] One of the second pressure strip 312 and the third connecting member 330 is provided with a fourth fastening screw 315, and the other of the second pressure strip 312 and the third connecting member 330 is provided with a fourth rivet nut 333, for example, Figure 4 As shown, the second pressure strip 312 is provided with a plurality of fourth fastening screws 315 distributed at intervals, and the third connecting member 330 is provided with a plurality of fourth rivet nuts 333 distributed at intervals.

[0095] During the actual implementation process, the first pressure strip 311 and the second pressure strip 312 are respectively installed at the first end and the second end of the middle piece 313, and the first pressure strip 311 and the second connecting piece 320 are connected by the third fastening screw 314 and the third rivet nut, and the second pressure strip 312 and the third connecting piece 330 are connected by the fourth fastening screw 315 and the fourth rivet nut 333. When installing the connecting protective cover 300, the second connecting piece 320 is connected to the first electrical equipment 100, and the third connecting piece 330 is connected to the second electrical equipment 200.

[0096] Through the arrangement of the above-mentioned first connecting member 310, the second connecting member 320 and the third connecting member 330, the flexible deformation of the first connecting member 310 can be used to compensate for the errors in the production and installation of the first electrical device 100 and the second electrical device 200.
