[0002] The function of the box-type transformer is to convert high-voltage electricity into low-voltage electricity and distribute it to end users. It also has protection, control and monitoring functions. A high-voltage cabinet, a low-voltage cabinet and a transformer connecting the two are set inside the box-type transformer. In the prior art, in the invention patent with publication number CN102299490A, a placement box for an intelligent distribution transformer terminal of a distribution transformer is disclosed, and a wiring structure is disclosed inside.

[0022] Example

[0023] This embodiment provides a wiring structure of a box-type transformer, which includes a first box body 1 for accommodating a transformer device 3 and a second box body 2 for accommodating a high-voltage cabinet. There is a space for the wires to pass through between the first box body 1 and the second box body 2. A wire trough 4 is provided below the first box body 1 for the wires to extend from one end close to the second box body 2 to the other end. The transformer device 3 is located above the wire trough 4.

[0024] The above specific improvements are: Figure 1 and Figure 2As shown, the box-type transformer includes a first box body 1 for accommodating a transformer device 3 and a second box body 2 for accommodating a high-voltage cabinet. The wires are connected to the high-voltage cabinet and then passed through the wire groove 4 of the first box body 1 to be connected to the transformer device 3. Compared with the existing technology, the wiring structure effectively shortens the wiring distance, thereby effectively saving costs. In the existing technology, the wires pass from the side, and workers need to step on the platform on the side when repairing, so that they will step on the wires during the repair process, causing damage to the wires. In this embodiment, the wires pass from the middle position of the bottom of the first box body 1. During maintenance, maintenance personnel will not step on the wires, thereby better protecting the wires.

[0025] Based on the above embodiment: a first shielding plate 5 and a second shielding plate 6 are respectively provided at both ends of the wire trough 4, the first shielding plate 5 is located at the end close to the first box body 1, and the second shielding plate 6 is located at the end of the wire trough 4 away from the first shielding plate 5, and the second shielding plate 6 is provided with a through hole 61 for the wire to pass through and connect to the transformer equipment 3.

[0026] The above specific improvements are: Figure 1-Figure 4 As shown, a first baffle 5 and a second baffle 6 are respectively provided on both sides of the wire trough 4. One end of the wire is connected from the high-voltage cabinet, passes through the gap between the first box body 1 and the second box body 2, enters the wire trough 4, and is then arranged along the direction in which the wire trough 4 is set. When the wire is installed in the wire trough 4, the first baffle 5 and the second baffle 6 are fixed to both sides of the wire trough 4 with fastening nails. A through-hole 61 is provided on the second baffle 6. The wire located in the wire trough 4 can pass outward along the through-hole 61 and be connected to the transformer equipment 3.

[0027] On the basis of the above embodiment: the wire trough 4 is arranged in an "I"-shaped structure, and an extension portion 41 is provided on the top of the two side walls of the wire trough 4, and the extension portion 41 is extended along the length direction of the wire trough 4, and the first shielding plate 5, the second shielding plate 6 and the extension portion 41 are connected with fastening nails.

[0028] The above specific improvements are: Figure 1 As shown, the wire trough 4 has an "I"-shaped structure, and extensions 41 are provided on both sides of the wire trough 4. There are circular holes on the first shielding plate 5 and the second shielding plate 6. There are screw holes on the extensions 41 that are aligned with the first shielding plate 5 and the second shielding plate 6. During installation, as long as the circular holes and the screw holes are aligned, the first shielding plate 5 and the second shielding plate 6 can be fixed above the wire trough 4. The setting of the first shielding plate 5 can press and hide the wires, effectively pressing the wires into the wire trough 4. The setting of the second shielding plate 6 and the circular hole above it can position the wires in the wire trough 4 while allowing the ends of the wires to pass through and be connected to the transformer device 3.

[0029] On the basis of the above embodiment: heat dissipation grooves 7 for assisting the transformer device 3 in dissipating heat are provided on both sides of the conductor groove 4 .
