[0032] Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. The various technical features of this utility model can be combined interactively without contradicting each other.

[0033] Reference Figure 1 , Figure 2 and Figure 3 This utility model embodiment proposes a connection structure that is more conducive to transformer connection. During the on-site connection process, it simplifies the tedious steps of on-site measurement and on-site fabrication of the connection structure, greatly shortens the connection time, and ensures effective connection. It also avoids the situation of inconsistent on-site fabrication processes and improves the efficiency of circuit connection.

[0034] In this embodiment, the splicing structure includes a terminal connector 100 and a protective cover 200. Referring to... Figure 3 and Figure 5The terminal connector 100 includes an A-phase line 120, a B-phase line 130, a C-phase line 140, an N-phase line 150, a ground line 160, and a starting section 110, which is the starting section 110 of the busbar trunking. The A-phase line 120, B-phase line 130, C-phase line 140, N-phase line 150, and ground line 160 are all connected to the starting section 110, and the ends of the A-phase line 120, B-phase line 130, C-phase line 140, N-phase line 150, and ground line 160 are respectively connected to conductors 170.

[0035] It is understandable that the conductor 170 connected to phase A line 120 is used to connect phase A of the transformer, the conductor 170 connected to phase B line 130 is used to connect phase B of the transformer, the conductor 170 connected to phase C line 140 is used to connect phase C of the transformer, the conductor 170 connected to phase N line 150 is used to connect phase N of the transformer, and the conductor 170 connected to ground line 160 is used for grounding.

[0036] The protective cover 200 is hollow to form a protective cavity and is provided with a wire passage hole 223. The wire passage hole 223 is connected to the protective cavity. All conductors 170 are placed inside the protective cavity. Phase A wire 120, phase B wire 130, phase C wire 140, phase N wire 150 and ground wire 160 pass through the wire passage hole 223 and are connected to the starting section 110 located outside the protective cavity. The starting section 110 can cover the wire passage hole 223, thereby sealing the protective cavity. The conductors 170 located inside the protective cavity can be sealed, which plays a role in safety protection.

[0037] During on-site construction, since the positions of the conductors 170 connected to the A-phase line 120, B-phase line 130, C-phase line 140, N-phase line 150 and ground line 160 are fixed and conform to the standard wiring form, after installing the protective cover 200 on the top cover of the transformer, the connection can be made directly. This eliminates the need for the traditional starting box, simplifies the tedious process of on-site measurement, fabrication, and design of the connection bar, and greatly improves the connection efficiency.

[0038] In this embodiment, the conductor 170 connected to the B-phase line 130 is designed to be suspended 300mm above the B-phase of the transformer, which is beneficial for making a soft connection with the B-phase of the transformer. Moreover, the conductor 170 connected to the B-phase line 130 is aligned with the outgoing end of the starting section 110.

[0039] Reference Figure 4In some embodiments, the conductors 170 connecting phase A 120 and phase C 140 extend along the width direction of the transformer, and their extension directions are opposite. Because the conductors 170 on phase A 120 and phase C 140 have appropriate lengths, they facilitate connection to phases A and C of the transformer.

[0040] In some embodiments, the terminal connector 100 further includes five flexible connectors, each of which is detachably connected to one of five conductors 170. The transformer achieves conductive connection with the conductors 170 through the flexible connectors, thereby completing the connection operation. It is understood that the flexible connectors can be copper braided strips, copper stranded wires, etc., and are not specifically limited here.

[0041] Understandably, flexible connectors have high flexibility, which can reduce the impact and wear caused by rigid connections.

[0042] In some embodiments, the connecting structure further includes an assembly beam 300 disposed on both sides of the protective cover 200. The assembly beam 300 extends along the width direction of the transformer, and its length is configured according to the width of the transformer. The assembly beam 300 is detachably connected to the top cover of the transformer, and the protective cover 200 is detachably connected to the assembly beam 300.

[0043] Specifically, the length of the assembly beam 300 is adjusted according to the actual measurement of the transformer casing, and the length of the protective cover 200 along the assembly beam 300 is determined according to the total length of the low-voltage side overlap of the transformer.

[0044] Understandably, the assembly beam 300 facilitates the installation of the connecting structure on the transformer's top cover by operators, and improves the installation stability of the connecting structure. Its detachability from the transformer's top cover also facilitates the repair and maintenance of the connecting structure or the transformer. Furthermore, since the assembly beam 300 is also detachable from the protective cover 200, it is easier to adjust the relative position of the protective cover 200 and the assembly beam 300 after installing the assembly beam 300 on the transformer's top cover, i.e., to adjust the relative position between the protective cover 200 and the transformer, so that the positions of each conductor 170 match the corresponding phase positions of the transformer.

[0045] In this embodiment, the assembly beam 300 is provided with a plurality of mounting holes, which are arranged along the length of the assembly beam 300. The mounting holes provide installation space for the connectors that connect the assembly beam 300 and the transformer. In this embodiment, the connectors used to connect the assembly beam 300 and the transformer are self-tapping screws, and the mounting holes are oblong holes.

[0046] Reference Figure 2 and Figure 3 In some embodiments, the protective cover 200 includes a cover body 210 and a cover plate 220. The cover body 210 and the cover plate 220 together form a protective cavity. The cover body 210 is detachably connected to the assembly beam 300 by self-tapping screws. The cover plate 220 is also detachably connected to the cover body 210 by self-tapping screws. A wire hole 223 is provided on the cover plate 220.

[0047] Understandably, during installation, the protective cover 200 is first installed on the transformer via the assembly beam 300. After the terminal connector 100 is connected to the transformer, the cover plate 220 is placed over the cover body 210, and the connection and fixation between the cover plate 220 and the cover body 210 are achieved. This is more conducive to the operation of construction personnel and achieves the safety protection of the conductor 170.

[0048] Reference Figure 7 In some embodiments, the cover plate 220 is provided with two plates 221, and each plate 221 has a stepped structure 222 on one side. The stepped structures 222 of the two plates 221 are arranged facing each other. During installation, when the stepped structures 222 of the two plates 221 are aligned, a notch is formed between the two stepped structures 222, which is the wire passage hole 223. In this embodiment, the wire passage hole 223 is rectangular.

[0049] In some embodiments, refer to Figure 6 The cover 210 is provided with an outer frame 211 and a reinforcing frame. The outer frame 211 is rectangular, and the reinforcing frame is located inside the outer frame 211 and connected to the outer frame 211. During installation, the plate 221 covers the reinforcing frame and the outer frame 211 and is detachably connected to the outer frame 211 and the reinforcing frame by self-tapping screws.

[0050] Specifically, the reinforcing frame includes two longitudinal bars 213 and two transverse bars 212. The two transverse bars 212 extend along the length of the assembled crossbeam 300. The two longitudinal bars 213 are perpendicular to the transverse bars 212. The two longitudinal bars 213 are respectively located on both sides of the center of the outer frame 211, and the two transverse bars 212 are respectively located on both sides of the center of the outer frame 211, outside the two longitudinal bars 213. During installation, the plate 221 can be connected to the longitudinal bars 213 and the transverse bars 212 using self-tapping screws. The longitudinal bars 213 and the transverse bars 212 will not interfere with the position of the wire hole 223 and can provide support for the plate 221.

[0051] In some embodiments, the conductors 170 connected to phase A 120, phase B 130, phase C 140, phase N 150, and ground 160 are of different colors. For example, the conductor 170 connected to phase A 120 is yellow, the conductor 170 connected to phase B 130 is green, the conductor 170 connected to phase C 140 is red, and the conductor 170 connected to phase N 150 is blue. This arrangement allows operators to easily distinguish the conductors 170 of each phase line during the connection process, thereby avoiding wiring errors and further improving connection efficiency and accuracy.

[0052] It is understood that the connection structure of this embodiment conforms to the busbar trunking erection standards and the specifications that must be met for on-site connections. It can be expanded to realize a series of efficient connection forms between transformers and busbar trunking of different specifications. The structure is standardized, easy to design, and convenient for production implementation.

[0053] Secondly, this utility model embodiment also proposes a power supply line transmission device, which includes the connection structure proposed in any of the embodiments of the first aspect above. It is understood that the power supply line transmission device also includes busbar trunking and a transformer. The busbar trunking and the transformer are quickly connected through the connection structure, realizing a key link in the operation of the power distribution line and further improving the efficiency of power supply construction.

[0054] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
