Description

Technical Field

[0001] The utility model relates to the technical field of box-type transformers, and particularly relates to a copper bar connection structure of a box-type transformer. Background Art

[0002] The function of a box-type transformer is to convert high-voltage electric energy into low-voltage electric energy and achieve safe and reliable power distribution and transmission. The copper bar is the "main current path" inside the box transformer, which converges and distributes electric energy in a highly reliable and low-loss manner to maintain the coordinated operation of each component. In the prior art, when the box-type transformer needs to be powered on after a power outage, electricity needs to be input from the emergency socket. However, in the actual use process, because there is no main switch, when electricity is input from the emergency socket, the entire current will be sent back to the high-voltage electrical equipment. Once someone is repairing at the high-voltage electrical equipment, it will cause electric shock to the maintenance personnel and endanger their lives. Content of the Utility Model

[0003] Therefore, the technical problem to be solved by the utility model is to overcome the defect in the prior art that when electricity is input from the emergency socket, the entire current will be sent back to the high-voltage electrical equipment, which may cause electric shock to upstream personnel, and thus provide a copper bar connection structure of a box-type transformer that can improve the installation performance.

[0004] To this end, the utility model provides a copper bar connection structure of a box-type transformer, which includes a box body and an emergency socket arranged inside the box body. A copper bar connected to an external high-voltage cabinet is arranged inside the box body, and an extension part for shielding the emergency socket is arranged at the copper bar.

[0005] Further: The copper bar includes a first connection bar and a second connection bar, and the first connection bar and the second connection bar are connected by fastening nails. The extension part is arranged on the first connection bar. One side of the second connection bar is connected to the side of the first connection bar facing away from the extension part, and the other side extends to the outside of the box body to be connected to the high-voltage cabinet. The first connection bar and the extension part are arranged in a "Z" shape.

[0006] Further: A positioning plate for positioning the emergency socket is arranged inside the box body, and a cover plate for covering the emergency socket is arranged on the positioning plate.

[0007] Further: A hinge shaft capable of connecting to the end of the cover plate is arranged on the positioning plate, and the cover plate can be flipped along the hinge shaft.

[0008] The technical solution of the utility model has the following advantages:

[0009] 1. The copper bar connection structure of a box-type transformer provided by the present utility model has the extension part of the copper bar shielding the outside of the emergency socket. In this way, when the copper bar is not removed, the plug on the external power generation vehicle cannot be inserted into the emergency socket. Only after the copper bar is removed, its extension part will not shield the outside of the emergency socket, and then the plug on the power generation vehicle can be normally inserted into the emergency socket. After the copper bar is removed, there will be a break point between the emergency socket and the external high-voltage cabinet. When the power is connected from the power generation vehicle, the current will not flow, so that the occurrence of electric shock accidents can be effectively avoided. At the same time, after the copper bar is removed, the power input of the power generation vehicle will replace the high-voltage cabinet to transmit power to the low-voltage cabinet, so as to supply power to users. After the high-voltage cabinet is repaired, the plug of the power generation vehicle is pulled out from the emergency socket, and then the copper bar can be assembled back to its original position, so that the high-voltage cabinet and the entire box-type transformer can continue to be energized.

[0019] Embodiment

[0020] This embodiment provides a copper bar connection structure for a box-type transformer, including a box body 1 and an emergency socket 2 arranged inside the box body 1. A copper bar 3 connected to an external high-voltage cabinet is arranged inside the box body 1, and an extension part 4 for shielding the emergency socket 2 is arranged at the copper bar 3.

[0021] The above specific improvement is as follows: As shown in Figure 1 and Figure 2 , compared with the prior art, the extension part 4 of the copper bar 3 shields the outside of the emergency socket 2. In this way, when the copper bar 3 is not removed, the plug on the external power generation vehicle cannot be inserted into the emergency socket 2. Only after the copper bar 3 is removed, its extension part 4 will not shield the outside of the emergency socket 2, and in this way, the plug on the power generation vehicle can be normally inserted into the emergency socket 2. After the copper bar 3 is removed, there will be a break point between the emergency socket 2 and the external high-voltage cabinet. When the power is connected from the power generation vehicle, the current will not flow, so that the occurrence of electric shock accidents can be effectively avoided. At the same time, after the copper bar 3 is removed, the power input of the power generation vehicle will replace the high-voltage cabinet to transmit power to the low-voltage cabinet, so as to supply power to users. After the high-voltage cabinet is repaired, when the plug of the power generation vehicle is pulled out from the emergency socket 2, the copper bar 3 can be assembled back to its original position, so that the high-voltage cabinet and the entire box-type transformer can continue to be energized.

[0022] On the basis of the above embodiment: the copper bar 3 includes a first connecting bar 31 and a second connecting bar 32, the first connecting bar 31 and the second connecting bar 32 are connected by fastening nails 33, the extension portion 4 is arranged on the first connecting bar 31, one side of the second connecting bar 32 is connected to the side of the first connecting bar 31 facing away from the extension portion 4, and the other side extends to the outside of the box body 1 and is connected to the high-voltage cabinet, and the first connecting bar 31 and the extension portion 4 are arranged in a "Z" shape structure.

[0023] The above specific improvements are: Figure 2 As shown, the copper bar 3 includes a first connecting bar 31 and a second connecting bar 32. The first connecting bar 31 and the second connecting bar 32 are connected by fastening nails 33. The second connecting bar 32 is connected to the external high-voltage cabinet. When disassembling, only the first connecting bar 31 needs to be disassembled to achieve the breakpoint between the high-voltage cabinet and the box-type transformer to avoid current reverse transmission.

[0024] On the basis of the above embodiment: a positioning plate 5 for positioning the emergency socket 2 is arranged inside the box body 1 , and a cover plate 6 for covering the emergency socket 2 is arranged on the positioning plate 5 .

[0025] On the basis of the above embodiment: the positioning plate 5 is provided with a hinge shaft 7 which can be connected to the end of the cover plate 6 , and the cover plate 6 can be turned over along the hinge shaft 7 .

[0026] The above specific improvements are: Figure 1 and Figure 2 As shown, a positioning plate 5 is arranged inside the box body 1, and a hinge shaft 7 is arranged on the positioning plate 5, and a cover plate 6 is connected at the hinge shaft 7. When the first connection row 31 is not removed, the cover plate 6 cannot be opened, and naturally the plug cannot be removed. When the first connection row 31 is removed, the cover plate 6 can be flipped upward so that the plug can be inserted into the emergency socket 2. A torsion spring is arranged in the hinge shaft 7 so that the cover plate 6 has an elastic restoring force. When the plug is pulled out, the cover plate 6 can be automatically reset. By setting the cover plate 6, the emergency socket 2 can be better protected to prevent dust from entering the emergency socket 2.

[0027] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
