Abstract
Description

When building a substation, the medium-voltage integrated machine needs to be transported to the designated installation location. The main way to transport the medium-voltage integrated machine is hoisting. Since the weight of the medium-voltage equipment is much greater than that of the low-voltage equipment, the connection protective cover at the connection between the medium-voltage equipment and the low-voltage equipment will be deformed when the medium-voltage integrated machine is hoisted, which will damage the low-voltage equipment or the medium-voltage equipment. At the same time, because the cost-reduction design of the integrated platform leads to reduced strength, the deformation of the connection between the medium-voltage equipment and the low-voltage equipment will be further increased during hoisting.

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 8 The connection protection cover 10 and the substation according to the embodiment of the present application are described.
[0050] The embodiment of the present application provides a connection protection cover 10, which is applied to a substation. The substation includes a first electrical device 20 and a second electrical device 30 electrically connected through a conductor 50, such as Figure 1-Figure 6 As shown, the connection protection cover 10 includes a first connection cover 100 , a second connection cover 200 and a shielding member 300 .
[0051] The conductor 50 includes a connection terminal of the first electrical device 20 , a connection terminal of the second electrical device 30 , and a copper bus or cable for connecting the two connection terminals.
[0052] There is a large weight difference between the first electrical device 20 and the second electrical device 30 . For example, the weight of the first electrical device 20 is much greater than the weight of the second electrical device 30 .
[0053] The first connection cover 100 may be a cylindrical structure, a trapezoidal structure or other shapes, such as Figure 1-Figure 6 As shown, the first connection cover 100 is a rectangular structure.
[0054] like Figure 5 and Figure 6 As shown, the first connection cover 100 is provided with a first connection structure 111 for connecting to the first electrical device 20 , and the first end of the first connection cover 100 is connected to the first electrical device 20 through the first connection structure 111 .
[0055] like Figure 5 and Figure 6 As shown, the first connection structure 111 can be a connection hole, and the first connection cover 100 and the first electrical device 20 are connected by bolts, pins or other connecting parts passing through the connection hole. The first connection structure 111 can also be a snap-fit part, an adhesive part or other structural parts used for connection.
[0056] The first connection cover 100 may be provided with a plurality of first connection structures 111, or may be provided with one first connection structure 111, for example, Figure 5 and Figure 6As shown, the first connection cover 100 is provided with a plurality of first connection structures 111 , and the plurality of first connection structures 111 are evenly distributed along the circumference of one end of the first connection cover 100 close to the first electrical device 20 .
[0057] like Figure 1 and Figure 2 As shown, the second connecting cover 200 is arranged outside the first connecting cover 100, and there is a gap between the second connecting cover 200 and the first connecting cover 100, the length of the second connecting cover 200 is greater than the length of the first connecting cover 100, the second connecting cover 200 can be placed as a whole in the first connecting cover 100, and there is a gap between the inner wall surface of the second connecting cover 200 and the outer wall surface of the first connecting cover 100.
[0058] like Figure 6 As shown, the second connection cover 200 is provided with a second connection structure 221 for connecting to the second electrical device 30 , and the second end of the second connection cover 200 is connected to the second electrical device 30 via the second connection structure 221 .
[0059] like Figure 6 As shown, the second connection structure 221 can be a connection hole, and the second connection cover 200 and the second electrical device 30 are connected by bolts, pins or other connecting parts passing through the connection hole. The first connection structure 111 can also be a snap-fit part, an adhesive part or other structural parts used for connection.
[0060] The second connection cover 200 may be provided with a plurality of second connection structures 221, or may be provided with one second connection structure 221, for example, Figure 6 As shown, the second connection cover 200 is provided with a plurality of second connection structures 221 , and the plurality of second connection structures 221 are evenly distributed along the circumference of one end of the second connection cover 200 close to the second electrical device 30 .
[0061] like Figure 1 and Figure 2 As shown, the first connection cover 100 and the second connection cover 200 are arranged outside the conductor 50, the first connection cover 100 and the second connection cover 200 are both hollow structures, and both ends of the first connection cover 100 and the second connection cover 200 are openings, the connection terminals of the first electrical device 20 and the connection terminals of the second electrical device 30 pass through the opening of the first connection cover 100 and the opening of the second connection cover 200 respectively and are located inside the first connection cover 100 and the second connection cover 200, and the connection terminals of the first electrical device 20 and the connection terminals of the second electrical device 30 are electrically connected through copper busbars or cables, that is, the copper busbars or cables are also located in the hollow parts of the first connection cover 100 and the second connection cover 200.
[0062] like Figure 1 and Figure 2As shown, the opening at one end of the first connection cover 100 close to the first electrical device 20 is connected to the first electrical device 20 and then closed, and the opening at one end of the second connection cover 200 close to the second electrical device 30 is connected to the second electrical device 30 and then closed. Since the second connection cover 200 is arranged outside the first connection cover 100, the opening at one end of the first connection cover 100 close to the second electrical device 30 cannot be connected to the external environment. The opening at one end of the second connection cover 200 close to the first electrical device 20 is not connected to the first electrical device 20, and there is a gap between the first connection cover 100 and the second connection cover 200, so the gap between the first connection cover 100 and the second connection cover 200 is in an open state.
[0063] The shielding member 300 is a flexible material member, and the shielding member 300 may be made of materials including but not limited to EPDM rubber, silicone rubber, chloroprene rubber, polyester, polyvinyl alcohol or other materials.
[0064] like Figure 1 and Figure 2 As shown, the shielding member 300 elastically stops between the first connection cover 100 and the second connection cover 200 and blocks the gap. The shielding member 300 elastically stops between the outer side of the first connection cover 100 close to the first electrical device 20 and the second connection cover 200. At this time, the opening of one end of the second connection cover 200 close to the first electrical device 20 is closed.
[0065] In the actual implementation process, after the first electrical device 20 and the second electrical device 30 are electrically connected through the conductor 50, the first electrical device 20 and the second electrical device 30 are lifted and transported at the same time. Since there is a large weight difference between the first electrical device 20 and the second electrical device 30, the first connection cover 100 and the second connection cover 200 will be deformed under the action of the first electrical device 20 and the second electrical device 30. For example, when the weight of the first electrical device 20 is much greater than the weight of the second electrical device 30, the downward movement tendency of the first electrical device 20 under the action of its own weight is greater than the downward movement tendency of the second electrical device 30. At this time, the end of the first connection cover 100 connected to the first electrical device 20 is deformed downward, and the end away from the first electrical device 20 is deformed upward. Since there is a gap between the first connection cover 100 and the second connection cover 200, the first connection cover 100 can be located in the gap between the two when deformed, that is, the gap between the first connection cover 100 and the second connection cover 200 provides a deformation space. Conversely, the deformation of the second connection cover 200 is the same.
[0066] In addition, a shielding member 300 is elastically stopped between the first connecting cover 100 and the second connecting cover 200. The first connecting cover 100 or the second connecting cover 200 will squeeze the shielding member 300 when deformed. Since the shielding member 300 is made of flexible material, the shielding member 300 will also be deformed when squeezed, and its own deformation provides space for the deformation of the first connecting cover 100 or the second connecting cover 200.
[0067] When the first electrical device 20 and the second electrical device 30 are installed outdoors, if a rodent wants to enter the connection protection cover 10, it may enter from the gap between the first connection cover 100 and the second connection cover 200, but a shielding member 300 is provided at the gap, so the rodent
[0068] By setting the above-mentioned first connection cover 100 and second connection cover 200, the conductor 50 can be protected; if the connection between the electrical equipment and the corresponding connection cover is broken, the terminal of the electrical equipment and the electrical equipment may be disconnected, causing damage to the electrical equipment. Therefore, by setting a gap between the first connection cover 100 and the second connection cover 200, a deformation space can be provided for the first connection cover 100 and the second connection cover 200 when the first electrical equipment 20 and the second electrical equipment 30 are lifted, thereby reducing the probability of the connection between the electrical equipment and the corresponding connection cover being broken due to deformation, and improving the safety of the connection protection cover 10 and the electrical equipment when lifting; by setting a shielding member 300 in the gap between the first electrical equipment 20 and the second electrical equipment 30, the probability of rodents entering the gap from the opening of the second connection cover 200 and gnawing the connection protection cover 10 or even the conductor 50 connected to the electrical equipment can be reduced, thereby improving the safety of the connection protection cover 10, the electrical equipment and the conductor 50. At the same time, the shielding member 300 is a flexible material member, which can reduce the influence of the shielding member 300 on the deformation of the connection protection cover 10.
[0069] According to the connection protection cover 10 provided in the embodiment of the present application, by setting a gap between the first connection cover 100 and the second connection cover 200, and setting a shielding member 300 at the gap, it is possible to provide space for the deformation of the first connection cover 100 and the second connection cover 200 while protecting the conductor 50, thereby reducing the probability of fracture at the connection between the electrical equipment and the corresponding connection cover due to deformation, and the shielding member 300 can reduce the probability of rodents entering the connection protection cover 10 and causing damage to the connection protection cover 10, the electrical equipment and the conductor 50, thereby extending the service life of the connection protection cover 10.
[0070] In some embodiments, Figure 1 and Figure 2 As shown, the shielding member 300 is connected to one of the first connection cover 100 and the second connection cover 200 , and elastically stops at the other of the first connection cover 100 and the second connection cover 200 .
[0071] The shielding member 300 may be connected to the first connection cover 100 and elastically stop against the second connection cover 200; the shielding member 300 may also be connected to the second connection cover 200 and elastically stop against the first connection cover 100, for example, Figure 1 and Figure 2 As shown, the shielding member 300 is connected to the first connection cover 100 and elastically stops at the second connection cover 200 .
[0072] The shielding member 300 may be connected to the first connection cover 100 or the second connection cover 200 by threaded connection, bonding, fasteners or other methods.
[0073] It can be understood that if the shielding member 300 is connected to both the first connecting cover 100 and the second connecting cover 200, the inner and outer sides of the shielding member 300 are in a fixed state. When the shielding member 300 is squeezed by the first connecting cover 100 or the second connecting cover 200, the shielding member 300 provides space for the deformation of the first connecting cover 100 and the second connecting cover 200 through the deformation of the middle part. However, if the shielding member 300 is made of rubber material and the deformation of the middle part is large, the middle part of the shielding member 300 is prone to crack, thereby reducing the service life of the shielding member 300.
[0074] Therefore, by setting the shielding member 300 to be connected to one of the first connecting cover 100 and the second connecting cover 200, and elastically stopping at the other of the first connecting cover 100 and the second connecting cover 200, the stability of the shielding member 300 at the gap can be improved, and the probability of rodents entering the gap due to the shielding member 300 being offset or falling off from the gap can be reduced.
[0075] In some embodiments, Figure 3 and Figure 4 As shown, the shielding member 300 includes a connecting structure 320 and a rib 310 .
[0076] The connection structure 320 is connected to the first end of the first connection cover 100 , and the connection structure 320 can be connected to the end of the first connection cover 100 close to the first electrical device 20 by threaded connection, bonding, fasteners or other methods.
[0077] like Figure 3 and Figure 4As shown, one end of the retaining edge 310 is connected to the connecting structure 320, and the other end is stopped at the second connecting cover 200. The retaining edge 310 and the connecting structure 320 are bent. The retaining edge 310 can be set along the height direction of the connecting protective cover 10, or along the direction forming an acute angle with the height direction; the connecting structure 320 can be set along the length direction of the connecting protective cover 10, or along the direction forming an acute angle with the length direction, that is, the connecting structure 320 can be close to being flush with the surface of the first connecting cover 100.
[0078] By setting the connecting structure 320 and the shielding member 300 to be bent, the contact area between the connecting structure 320 and the surface of the first connecting cover 100 can be increased, thereby improving the connection stability between the connecting structure 320 and the first connecting cover 100, and at the same time reducing the damage to the shielding member 300 caused by the first connecting cover 100 or the second connecting cover 200 squeezing the shielding member 300.
[0079] In some embodiments, Figure 3 and Figure 4 As shown, the first end of the first connecting cover 100 is provided with an outwardly protruding flange 112, and the connecting structure 320 includes a first section 321, a second section 322 and a third section 323 connected in sequence, the first section 321 and the second section 322 are bent, the second section 322 and the third section 323 are bent, and the first section 321 and the third section 323 are both located on the same side of the second section 322, and the flange 112 is clamped between the first section 321 and the third section 323.
[0080] Among them, Figure 3 and Figure 4 As shown, the flange 112 protrudes outward along the length direction relative to the first end of the first connection cover 100 , and the flange 112 is provided around the first end of the first connection cover 100 .
[0081] like Figure 3 and Figure 4 As shown, the retaining edge 310 may be connected to the connection point between the first section 321 and the second section 322 of the connecting structure 320 , or may be connected to other positions of the first section 321 or the second section 322 .
[0082] like Figure 3 and Figure 4 As shown, the first section 321 and the third section 323 of the connection structure 320 are both located on the side of the second section 322 facing the flange 112 , and the first section 321 , the second section 322 and the third section 323 connected in sequence form a groove, the opening of the groove faces the flange 112 .
[0083] In the actual implementation process, when assembling the shielding member 300 and the first connecting cover 100, the flange 112 at the first end of the first connecting cover 100 is inserted into the groove formed by the shielding member 300, that is, the flange 112 is clamped between the first section 321 and the third section 323 of the connecting structure 320, and the position of the shielding member 300 on the first connecting cover 100 is maintained by the friction force between the first section 321 and the third section 323 and the flange 112.
[0084] By setting the above-mentioned first section 321, second section 322 and third section 323, the flange 112 of the first connecting cover 100 can be clamped on the connecting structure 320 of the shielding member 300. The structure is simple and the assembly method is simple, which is convenient for disassembly of the shielding member 300 when the shielding member 300 is replaced later.
[0085] In some embodiments, Figure 3 and Figure 4 As shown, the distance between the first section 321 and the third section 323 gradually decreases in the direction away from the second section 322 .
[0086] Among them, Figure 3 and Figure 4 As shown, the width of the groove formed between the first section 321, the second section 322 and the third section 323 gradually decreases from the side close to the second section 322 to the side away from the second section 322, that is, the width of the groove is smaller at the entrance.
[0087] In the actual implementation process, when the flange 112 is inserted into the groove formed by the connecting structure 320, the end of the flange 112 close to the connecting structure 320 is inserted from the side of the groove away from the second section 322. At this time, the friction between the first section 321 and the third section 323 and the end of the flange 112 is relatively large, and the end of the flange 112 continues to move into the groove. As the width of the groove gradually increases, the friction between the end of the flange 112 and the first section 321 and the third section 323 gradually decreases or even disappears; at the same time, the ends of the first section 321 and the third section 323 away from the second section 322 always maintain a large friction with the flange 112 during the insertion process of the flange 112, that is, the flange 112 is clamped by the first section 321 and the third section 323 at any position in the groove.
[0088] By setting the distance between the first section 321 and the third section 323 to gradually decrease in the direction away from the second section 322, the flange 112 can be clamped by the first section 321 and the third section 323 at any position in the groove, thereby reducing the probability of the covering member 300 falling off the flange 112. At the same time, in the process of gradually inserting the flange 112 into the groove, the friction between the flange 112 and other positions of the first section 321 and the third section 323 is reduced, so as to facilitate the insertion of the flange 112.
[0089] In some embodiments, Figure 3 and Figure 4 As shown, the shielding member 300 further includes a friction member 330 . The friction member 330 is disposed between the first section 321 and the third section 323 , and one end of the friction member 330 abuts against the flange 112 .
[0090] Among them, Figure 3 and Figure 4 As shown, the width of the groove at other positions except the end away from the second section 322 can be greater than the thickness of the flange 112, that is, there is no friction between the first section 321 and the third section 323 and the flange 112 at other positions except the end away from the second section 322.
[0091] The friction member 330 may be a triangular structure, a trapezoidal structure or other shapes, for example, Figure 3 and Figure 4 As shown, the friction member 330 is a rectangular structure.
[0092] The friction member 330 may be multiple, one end of some friction members 330 is connected to the first section 321, and the other end is used to stop against the flange 112, and one end of another friction member 330 is connected to the third section 323, and the other end is used to stop against the flange 112, for example, Figure 3 and Figure 4 As shown, there are four friction members 330 , one end of two friction members 330 is connected to the first section 321 , one end of the other two friction members 330 is connected to the third section 323 , and the multiple friction members 330 can be cross-arranged along the thickness direction of the groove.
[0093] like Figure 3 and Figure 4 As shown, one end of the friction member 330 close to the flange 112 can be configured as an arc structure to reduce the probability of the friction member 330 damaging the flange 112 .
[0094] During the actual implementation process, when the flange 112 is inserted into the groove formed by the connecting structure 320, the end of the flange 112 close to the connecting structure 320 is inserted from the side of the groove away from the second section 322, and after passing through the end of the first section 321 and the third section 323 away from the second section 322, the flange 112 contacts the friction member 330. Since the friction member 330 is a flexible material, the friction member 330 is deformed under the action of the flange 112 and stops against the surface of the flange 112, that is, there is a certain friction force between the friction member 330 and the flange 112, and the flange 112 can continue to be inserted to the specified position.
[0095] By setting the above-mentioned friction member 330, while facilitating the insertion of the flange 112, the friction force between the flange 112 and other positions of the first section 321 and the third section 323 except the end away from the second section 322 is increased, thereby improving the clamping force of the connection structure 320 on the flange 112.
[0096] In some embodiments, Figure 3 and Figure 4 As shown, the rib 310 is an arc-shaped structure, and the center of curvature of the rib 310 is located on a side of the first connection cover 100 close to the first electrical device 20 and is arranged toward the central axis of the first connection cover 100 .
[0097] Among them, Figure 3 and Figure 4 As shown, the center of curvature of the arc-shaped structure of the rib 310 is located on the side of the first connection cover 100 close to the first electrical device 20 and is arranged toward the central axis of the first connection cover 100 , that is, the rib 310 is recessed in a direction away from the first electrical device 20 .
[0098] In the actual implementation process, when a rodent wants to enter the gap and hits the sidewall 310 of the shielding member 300 from the outside, the sidewall 310 is deformed under the force of the rodent, and deforms from an arc structure to a vertical structure. Since the height of the sidewall 310 in the vertical state is greater than the width of the gap, the greater the deformation of the sidewall 310, the greater the friction between the sidewall 310 and the second connecting cover 200, and it is more difficult for rodents to enter the gap.
[0099] It can be understood that if the center of curvature of the rib 310 is located on the side of the first connecting cover 100 away from the first electrical device 20, and is set toward the central axis of the first connecting cover 100, the rib 310 is recessed in the direction toward the first electrical device 20. At this time, if a rodent hits the rib 310 from the opening of the second connecting cover 200 close to the first electrical device 20, the rib 310 bends under the action of external force, and the end of the rib 310 that stops at the second connecting cover 200 is separated from the second connecting cover 200. At this time, the rodent can enter the connecting protective cover 10 from between the second connecting cover 200 and the rib 310.
[0100] In other embodiments, the retaining edge 310 may also be a planar structure, a wavy structure, a spherical structure or other shapes.
[0101] By setting the retaining edge 310 as an arc-shaped structure, and the center of curvature of the retaining edge 310 is located on the side of the first connecting cover 100 close to the first electrical device 20, and is set toward the central axis of the first connecting cover 100, the blocking effect of the shielding member 300 on the gap can be further improved, and the probability of rodents entering the connecting protective cover 10 and causing damage to the connecting protective cover 10 and the electrical equipment can be further reduced.
[0102] In some embodiments, a repelling structure for repelling animals is provided on a side of the rib 310 facing away from the first connecting cover 100 .
[0103] The side surface of the retaining edge 310 facing away from the second electrical device 30 may be provided with sharp spikes, or a thin metal layer may be provided on the side surface, or anti-rodent agents and other ingredients that repel animals may be added to the material used to make the retaining edge 310 .
[0104] By providing a repelling structure for repelling animals on the side of the retaining edge 310 away from the first connection cover 100, the probability of rodents approaching the connection protection cover 10 can be reduced, and the probability of rodents knocking open the shielding member 300 can be reduced, further improving the safety of the connection protection cover 10 and the electrical equipment.
[0105] In some embodiments, Figure 5 and Figure 6 As shown, the first connection cover 100 includes a rigid connection cover 110 and a flexible connection cover 120 .
[0106] Among them, Figure 5 and Figure 6 As shown, the rigid connection cover 110 is arranged on the side of the flexible connection cover 120 close to the first electrical device 20, the first end of the rigid connection cover 110 is provided with a first connection structure 111, the first end of the rigid connection cover 110 is provided with an outwardly protruding flange 112, and one end of the shielding member 300 is connected to the flange 112.
[0107] The rigid connection cover 110 may be made of materials including but not limited to aluminum alloy, carbon steel, cast steel, alloy steel, and the like.
[0108] like Figure 5 and Figure 6 As shown, the first end of the flexible connection cover 120 is connected to the second end of the rigid connection cover 110 , and the flexible connection cover 120 and the rigid connection cover 110 can be connected by threaded connection, bonding, snap connection or other methods.
[0109] The flexible connection cover 120 and the shielding member 300 may be made of materials including but not limited to rubber, polyimide, polyester, polyvinyl alcohol or other materials, which are not specifically limited here.
[0110] In some embodiments, when the first connection cover 100 is deformed under the influence of the first electrical device 20, the flexible connection cover 120 elastically deforms at one end close to the rigid connection cover 110. At this time, the external force generated by the first electrical device 20 on the first connection cover 100 is flexibly compensated by the deformation of the flexible connection cover 120.
[0111] By configuring the rigid connection cover 110 and the flexible connection cover 120 as described above, flexible compensation can be performed through the elastic deformation of the flexible connection cover 120, thereby reducing damage to the first connection cover 100 caused by deformation.
[0112] In some embodiments, Figure 1 and Figure 2 As shown, the second connection cover 200 includes a first sub-connection cover 210 and a second sub-connection cover 220 .
[0113] Among them, Figure 1 and Figure 2 As shown, the first sub-connection cover 210 is arranged outside the first connection cover 100, and the first sub-connection cover 210 may include an upper connection cover 211 and a lower connection cover 212. The upper connection cover 211 is located above the first connection cover 100, and the lower connection cover 212 may be a U-shaped structure, and the lower connection cover 212 is located below the upper connection cover 211, and the upper end of the lower connection cover 212 is connected to the upper connection cover 211.
[0114] like Figure 1 and Figure 2 As shown, there is a gap between the first sub-connection cover 210 and the first connection cover 100 , that is, there is a gap between the inner wall surfaces of the upper connection cover 211 and the lower connection cover 212 and the first connection cover 100 .
[0115] like Figure 1 and Figure 2 As shown, the first end of the second sub-connection cover 220 is connected to the first sub-connection cover 210, and the second end of the second sub-connection cover 220 is provided with a second connection structure 221 for connecting to the second electrical device 30. The second sub-connection cover 220 and the first connection cover 100 are distributed along the length direction. The end of the second sub-connection cover 220 close to the first connection cover 100 is provided with an outward folded edge, and the end of the first sub-connection cover 210 close to the second sub-connection cover 220 is provided with an inward folded edge. The folded edge of the first sub-connection cover 210 and the folded edge of the second sub-connection cover 220 can be connected by threaded connection, bonding, welding or other methods.
[0116] like Figure 1 and Figure 2 As shown, the first connection cover 100 and the second sub-connection cover 220 are disposed outside the conductor 50, and the first connection cover 100 and the second sub-connection cover 220 are connected to the first electrical device 20 and the second electrical device 30 respectively.
[0117] The first sub-connection cover 210 and the second sub-connection cover 220 are both rigid structural parts, and can be made of materials including but not limited to aluminum alloy, carbon steel, cast steel, alloy steel, etc.
[0118] Through the arrangement of the above-mentioned first sub-connection cover 210 and the second sub-connection cover 220, the first sub-connection cover 210 can be used to protect the flexible connection cover 120, thereby reducing the probability of damage to the flexible connection cover 120 caused by objects in the external environment. The first sub-connection cover 210 is arranged to include an upper connection cover 211 and a lower connection cover 212, which can facilitate the installation of the first sub-connection cover 210 after the first connection cover 100 and the second sub-connection cover 220 are assembled. At the same time, the second sub-connection cover 220 can be used to connect to the second electrical equipment 30, thereby improving the connection stability between the connection protection cover 10 and the second electrical equipment 30.
[0119] In some embodiments, Figure 1 and Figure 2 As shown, the minimum gap distance d between the first sub-connection cover 210 and the first connection cover 100 satisfies: d≥d1, where d1 is the maximum lifting deformation of the first connection cover 100.
[0120] Among them, Figure 1 and Figure 2 As shown, the maximum lifting deformation can be set based on factors such as the material, structure, and size of the first connecting cover 100. By setting the minimum gap distance d between the first sub-connecting cover 210 and the first connecting cover 100 to satisfy d≥d1, the risk of fracture between the first electrical equipment 20 and the first connecting cover 100 caused by the difficulty in deforming the first connecting cover 100 can be further reduced.
[0121] In some embodiments, Figure 1 and Figure 2 As shown, the first end of the second sub-connection cover 220 abuts against the second end of the first connection cover 100 .
[0122] Among them, Figure 1 and Figure 2 As shown, one end of the flexible connection cover 120 facing away from the rigid connection cover 110 abuts against one end of the second sub-connection cover 220 facing away from the second electrical device 30 .
[0123] In the actual implementation process, when the first connecting cover 100 or the second connecting cover 200 is deformed, the flexible connecting cover 120 and the second sub-connecting cover 220 can be separated. At this time, the deformation of the first connecting cover 100 is difficult to be transmitted to the second connecting cover 200, and the deformation of the second connecting cover 200 is difficult to be transmitted to the first connecting cover 100. If the first connecting cover 100 is connected to the second sub-connecting cover 220, the second connecting cover 200 and the first connecting cover 100 may split when the deformation is large.
[0124] By abutting the first end of the second sub-connection cover 220 against the second end of the first connection cover 100 , the probability of the first connection cover 100 and the second connection cover 200 being split can be reduced.
[0125] The present application also provides a substation, such as Figure 1 , Figure 7 and Figure 8 As shown, the substation includes an integrated platform 40, a first electrical device 20 and a second electrical device 30 electrically connected via an electrical conductor 50, and a connection protection cover 10 as in any of the above embodiments.
[0126] Among them, Figure 1 , Figure 7 and Figure 8 As shown, the first electrical device 20 may be a medium voltage device, the second electrical device 30 may be a low voltage device, the first electrical device 20 and the second electrical device 30 are installed on an integrated platform 40 , and the connection protection cover 10 is disposed outside the conductor 50 .
[0127] According to the substation provided in the embodiment of the present application, by adopting the connection protection cover 10 of any of the above-mentioned embodiments, it is possible to provide space for the deformation of the first connection cover 100 and the second connection cover 200 while protecting the conductor 50, thereby reducing the probability of fracture at the connection between the electrical equipment and the corresponding connection cover due to deformation, and the shielding member 300 can reduce the probability of rodents entering the connection protection cover 10 and causing damage to the connection protection cover 10, the electrical equipment and the conductor 50, thereby extending the service life of the connection protection cover 10.
