Description

Technical Field

[0001] The utility model relates to an electrical equipment connection structure, more specifically, it relates to a busbar bridge and a switch cabinet busbar soft connection structure Background Art

[0002] Nowadays, many factories are built near the sea for the convenience of transporting raw materials or products. However, there are many disadvantages in building factories on land reclaimed from the sea. The geology is soft and the water content is high. After a long time, the foundation will sink, causing various components connected by hard links to be stressed and causing safety hazards. In terms of electricity, the power system in the factory area is formed by connecting various electrical equipment to each other. There are many places with hard connections. Among them, the connection between the transformer and the switch cabinet is often connected through various special busbar bridges, such as tubular busbars, trough busbars, and dense busbars. However, such busbars are rigid structures, connecting the busbar to the busbar in the switch cabinet. If the foundation settlement causes slight deformation and mechanical displacement of the equipment, it will cause tension at the connection, resulting in the busbar or busbar being stressed or deformed. The overlap area at the busbar connection is insufficient or the loose belt only heats up, causing safety hazards.

[0003] For example: Chinese patent announcement number CN202817506U, announcement date March 20, 2013, the name of the utility model is an adjustable, assembled low-voltage busbar bridge, the application discloses a busbar bridge connection structure, including a shell, a busbar and a busbar fixing device, the shell includes three structural components: a transformer transfer box, a connecting bridge, and a switch cabinet transfer box, the transformer transfer box and the switch cabinet transfer box are connected together through a connecting bridge, and each structural component is an assembled structure; in this scheme, each structural component is a standardized structure, which can be adjusted according to the on-site conditions, improve production efficiency, and greatly shorten the project cycle. However, in this scheme, the connections between the three structural components of the transformer transfer box, the connecting bridge, and the switch cabinet transfer box are all rigid connections. When the position of one of the structural components changes, all devices will fail, posing a safety risk. Utility Model Content

In this solution, a soft connection structure is adopted to adapt to the position change between the busbar bridge and the busbar structure, and the braided belt in the soft connection structure can be bent and deformed. When the distance between the busbar bridge and the busbar structure changes, the braided belt can compensate for the distance change between the two in real time, and the connecting plate is used to connect with the busbar structure and the busbar bridge to improve the connection strength and stability.

[0008] Preferably, the two connecting plates are provided with laser distance measuring modules. The laser distance measuring modules on the connecting plates can detect the vertical distance between the bus bridge and the busbar, so as to monitor the position change between the bus bridge and the busbar in real time, so as to facilitate the operator to understand the settlement situation, and when the position change exceeds the safe range, the operator can be prompted to perform maintenance.

DETAILED DESCRIPTION

[0021] The technical solution of the utility model is further described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0022] Example 1. Figure 1 and Figure 2 A busbar bridge and switch cabinet busbar soft connection structure shown includes a busbar bridge 1 and a switch cabinet 7. A busbar chamber 7.1 is provided inside the switch cabinet 7. A busbar 2 structure is provided at the bottom of the busbar chamber 7. The busbar bridge 1 is in a suspended state. Specifically, a suspension rod assembly is provided on the busbar bridge 1, and the busbar bridge 1 is suspended by the suspension rod assembly. The left side of the busbar bridge 1 is a connection end, and the connection end of the busbar bridge 1 is penetrated into the busbar chamber 7.1 of the switch cabinet 7 through the wall bushing of the switch cabinet 7; the wall bushing is a hole structure on the side panel of the busbar chamber 7.1 of the switch cabinet 7. Generally, there are multiple wall bushings, which can be penetrated into structures such as busbars; the wall bushing is located at the top position of the side panel of the busbar chamber 7.1, so that when the busbar bridge 1 is penetrated into the busbar chamber 7.1, the busbar bridge 1 is located above the busbar 2.

[0023] In the actual process, the connection end of the busbar bridge 1 is provided with four-phase dense busbars, namely, the dense busbar of phase A, the dense busbar of phase B, the dense busbar of phase C, and the dense busbar of phase N; and the bottom of the busbar chamber 7.1 is also provided with four-phase busbars 2 corresponding to the above four-phase dense busbars; each phase dense busbar corresponds to one phase busbar 2, and the busbar is located directly above the busbar 2, and each dense busbar is parallel to the corresponding busbar 2 structure. Four groups of soft connection structures 3 are provided between the busbar 2 and the dense busbar, and each group of soft connection structures 3 respectively connects one phase dense busbar and the corresponding phase busbar 2 structure.

[0024] like Figure 3As shown, the soft connection structure 3 includes a braided belt 3.1 and two connecting plates 3.2. The two connecting plates 3.2 are respectively connected to the two sides of the braided belt 3.1. The braided belt 3.1 is a mesh structure woven from a conductive material. Specifically, the braided material can be made of copper wire; the copper wire can not only play a conductive role, but also has a certain flexibility and can be bent and stretched. In addition to being connected to the braided belt 3.1, the two connecting plates 3.2 are also connected to the connecting end of the bus bridge 1 and the busbar 2. Specifically, one end of one of the connecting plates 3.2 is connected to the lower end of the braided belt 3.1, and the other end is connected to the busbar 2 at the bottom of the bus chamber 7.1; one end of the other connecting plate 3.2 is connected to the upper end of the braided belt 3.1, and the other end is connected to the dense bus on the bus bridge 1. The braided belt 3.1 is in an arc shape as a whole. When the height position of the switch cabinet 7 changes due to the foundation settlement, the height position of the busbar 2 structure in the switch cabinet 7 will also be reduced to a certain extent. The arc-shaped structure on the braided belt 3.1 can be slowly straightened to compensate for the displacement change value. In addition, the shape of the braided belt 3.1 can be an arc or an angle; it can be in a non-straight state, and maintaining a certain bending state can compensate for the displacement. It also greatly reduces the installation accuracy requirements between the busbar bridge 1 and the busbar 2 structure.

[0025] like Figure 2 As shown, on each phase dense busbar at the connection end of the busbar bridge 1, a fork arm 1.1 is provided, the fork arm 1.1 is bent at 90 degrees, and the fork arm 1.1 of each phase is located directly above the busbar 2 of the corresponding phase, and the fork arm 1.1 is parallel to the busbar 2.

Specifically, a copper plate structural material can be used, and the connecting plate 3.2 and the braided belt 3.1 need to be fixedly connected. Specifically, the connecting plate 3.2 and the braided belt 3.1 are connected by hot melt to form a whole, which improves their conductive performance on the one hand and improves the structural connection strength between the two on the other hand.

[0027] In addition, if Figure 1 As shown, in this solution, there are at least two groups of hanger assemblies (only two groups are shown in the figure), each group of hanger assemblies includes two threaded tie rods 5, the bottom of the threaded tie rods 5 is provided with threads, the busbar bridge 1 is arranged in the busbar duct, the two threaded tie rods 5 are respectively arranged on both sides of the busbar duct, and a nut structure is arranged at the thread at the bottom of the threaded tie rods 5, the nut can play a role of lifting and supporting the busbar duct, so that the busbar bridge can be suspended.

[0028] An insulator 6 is provided between the busbar 2 and the bottom of the busbar chamber 7.1 of the switch cabinet 7. The insulator 6 supports the busbar 2 and ensures that there is a certain insulation distance between the busbar 2 and the switch cabinet 7 body.

[0029] It should also be noted that the distance between the soft connection structures 3 of different phases has also changed. The safe distance is uncontrollable and there may be risks. Therefore, an insulating sleeve is wrapped around the braided belt 3.1 structure in the middle of each phase soft connection structure 3 to ensure the insulation safety between phases.

[0030] Example 2: Figures 1 to 4 A busbar bridge and switch cabinet busbar soft connection structure shown includes a busbar bridge 1 and a switch cabinet 7. A busbar chamber 7.1 is provided inside the switch cabinet 7. A busbar 2 structure is provided at the bottom of the busbar chamber 7. The busbar bridge 1 is in a suspended state.

Generally, there are multiple wall bushings, which can be penetrated into structures such as busbars; the wall bushing is located at the top position of the side panel of the busbar chamber 7.1, so that when the busbar bridge 1 is penetrated into the busbar chamber 7.1, the busbar bridge 1 is located above the busbar 2.

[0031] In the actual process, the connection end of the busbar bridge 1 is provided with four-phase dense busbars, namely, the dense busbar of phase A, the dense busbar of phase B, the dense busbar of phase C, and the dense busbar of phase N; and the bottom of the busbar chamber 7.1 is also provided with four-phase busbars 2 corresponding to the above four-phase dense busbars; each phase dense busbar corresponds to one phase busbar 2, and the busbar is located directly above the busbar 2, and each dense busbar is parallel to the corresponding busbar 2 structure. Four groups of soft connection structures 3 are provided between the busbar 2 and the dense busbar, and each group of soft connection structures 3 respectively connects one phase dense busbar and the corresponding phase busbar 2 structure.

[0032] The soft connection structure 3 includes a braided belt 3.1 and two connecting plates 3.2. The two connecting plates 3.2 are respectively connected to the two sides of the braided belt 3.1. The braided belt 3.1 is a mesh structure woven from a conductive material. Specifically, the braided material can be made of copper wire; the copper wire can not only play a conductive role, but also has a certain flexibility and can be bent and stretched. In addition to being connected to the braided belt 3.1, the two connecting plates 3.2 are also connected to the connecting end of the bus bridge 1 and the busbar 2. Specifically, one end of one of the connecting plates 3.2 is connected to the lower end of the braided belt 3.1, and the other end is connected to the busbar 2 at the bottom of the bus chamber 7.1; one end of the other connecting plate 3.2 is connected to the upper end of the braided belt 3.1, and the other end is connected to the dense bus on the bus bridge 1. The braided belt 3.1 is in an arc shape as a whole.

The arc-shaped structure on the braided belt 3.1 can be slowly straightened to compensate for the displacement change value. In addition, the shape of the braided belt 3.1 can be an arc or an angle; it can be in a non-straight state, and maintaining a certain bending state can compensate for the displacement. It also greatly reduces the installation accuracy requirements between the busbar bridge 1 and the busbar 2 structure.

A connecting hole 3.2.2 is also provided on the connecting plate 3.2. When the busbar 2 or the forked hand 1.1 is matched with the U-shaped groove 3.2.1, the busbar 2 or the forked hand 1.1 is completely fixedly connected with the connecting plate 3.2 by setting bolts and other structures in the connecting hole 3.2.2. In order to ensure the stability of the connection, four groups of connecting holes 3.2.2 are respectively provided, which are distributed in a matrix on the connecting plate 3.2.

[0035] In this solution, the connecting plate 3.2 is also made of conductive material. Specifically, a copper plate structural material can be used, and the connecting plate 3.2 and the braided belt 3.1 need to be fixedly connected. Specifically, the connecting plate 3.2 and the braided belt 3.1 are connected by hot melt to form a whole, which improves their conductive performance on the one hand and improves the structural connection strength between the two on the other hand.

[0036] In addition, if Figure 1 As shown, in this solution, there are at least two groups of hanger assemblies (only two groups are shown in the figure), each group of hanger assemblies includes two threaded tie rods 5, the bottom of the threaded tie rods 5 is provided with threads, the busbar bridge 1 is arranged in the busbar duct, the two threaded tie rods 5 are respectively arranged on both sides of the busbar duct, and a nut structure is arranged at the thread at the bottom of the threaded tie rods 5, the nut can play a role of lifting and supporting the busbar duct, so that the busbar bridge can be suspended.

[0037] An insulator 6 is provided between the busbar 2 and the bottom of the busbar chamber 7.1 of the switch cabinet 7. The insulator 6 supports the busbar 2 and ensures that there is a certain insulation distance between the busbar 2 and the switch cabinet 7 body.

[0038] It should also be noted that the distance between the soft connection structures 3 of different phases has also changed. The safe distance is uncontrollable and there may be risks. Therefore, an insulating sleeve is wrapped around the braided belt 3.1 structure in the middle of each phase soft connection structure 3 to ensure the insulation safety between phases.

[0039] Example 3: Figures 1 to 4 A busbar bridge and switch cabinet busbar soft connection structure shown includes a busbar bridge 1 and a switch cabinet 7. A busbar chamber 7.1 is provided inside the switch cabinet 7. A busbar 2 structure is provided at the bottom of the busbar chamber 7. The busbar bridge 1 is in a suspended state.

Four groups of soft connection structures 3 are provided between the busbar 2 and the dense busbar, and each group of soft connection structures 3 respectively connects one phase dense busbar and the corresponding phase busbar 2 structure.

[0041] The soft connection structure 3 includes a braided belt 3.1 and two connecting plates 3.2. The two connecting plates 3.2 are respectively connected to the two sides of the braided belt 3.1. The braided belt 3.1 is a mesh structure woven from a conductive material. Specifically, the braided material can be made of copper wire; the copper wire can not only play a conductive role, but also has a certain flexibility and can be bent and stretched. In addition to being connected to the braided belt 3.1, the two connecting plates 3.2 are also connected to the connecting end of the bus bridge 1 and the busbar 2.

The braided belt 3.1 is in an arc shape as a whole. When the height position of the switch cabinet 7 changes due to the foundation settlement, the height position of the busbar 2 structure in the switch cabinet 7 will also be reduced to a certain extent. The arc-shaped structure on the braided belt 3.1 can be slowly straightened to compensate for the displacement change value. In addition, the shape of the braided belt 3.1 can be an arc or an angle; it can be in a non-straight state, and maintaining a certain bending state can compensate for the displacement. It also greatly reduces the installation accuracy requirements between the busbar bridge 1 and the busbar 2 structure.

[0042] like Figure 2 As shown, on each phase dense busbar at the connection end of the busbar bridge 1, a fork arm 1.1 is provided, the fork arm 1.1 is bent at 90 degrees, and the fork arm 1.1 of each phase is located directly above the busbar 2 of the corresponding phase, and the fork arm 1.1 is parallel to the busbar 2.

In order to ensure the stability of the connection, four groups of connecting holes 3.2.2 are respectively provided, which are distributed in a matrix on the connecting plate 3.2.

[0044] In this solution, the connecting plate 3.2 is also made of conductive material. Specifically, a copper plate structural material can be used, and the connecting plate 3.2 and the braided belt 3.1 need to be fixedly connected. Specifically, the connecting plate 3.2 and the braided belt 3.1 are connected by hot melt to form a whole, which improves their conductive performance on the one hand and improves the structural connection strength between the two on the other hand.
