Description

Technical Field

[0001] This utility model relates to the field of switchgear, and in particular to a switchgear with a suspended current transformer. Background Technology

[0002] Switchgear is an electrical device whose main function is to open, close, control, and protect electrical equipment during power generation, transmission, distribution, and energy conversion in a power system. Current transformers are essential components of switchgear, reducing the large current in high-voltage circuits by a fixed ratio for safe use by subsequent metering, protection, and monitoring equipment. Currently, current transformers are typically installed at the rear of the switchgear cabinet. Specifically, the current transformer is first installed on the rear door panel outside the cabinet, and then the rear door panel is installed on the cabinet body, placing the current transformer inside the cabinet. This installation method has drawbacks. When connecting the copper busbars to the transformer, the screws and insulating plates of the copper busbars are easily obstructed by the current transformer, leading to inconvenient connections and increased time consumption. Furthermore, this connection method also makes it inconvenient for users to connect cables. Utility Model Content

[0003] The purpose of this utility model is to provide a switch cabinet with a suspended current transformer, which includes: a cabinet body, the cabinet body including a top plate, a front door plate, a rear door plate and a partition, the partition extending longitudinally between the front door plate and the rear door plate, the partition dividing the cabinet body into a front area and a rear area, the rear area having a busbar compartment for accommodating busbars, the busbar compartment having a mounting plate, the mounting plate including a horizontal plate extending in a horizontal direction and a vertical plate perpendicular to the horizontal plate, the end of the horizontal plate away from the vertical plate being connected to the partition, and the end of the vertical plate away from the horizontal plate being connected to the top plate; A current transformer includes an upper mounting surface that can be mounted against the lower surface of the horizontal plate. The upper mounting surface includes a first mounting hole through which a locking fastener passes to connect the upper mounting surface to the horizontal plate.

[0004] Furthermore, the longitudinal plate is provided with a through groove.

[0005] Furthermore, the horizontal plate is provided with a second mounting hole corresponding to the first mounting hole. When the second mounting hole is aligned with the first mounting hole, the fastener can pass through the first mounting hole and the second mounting hole to connect the upper mounting surface of the current transformer to the horizontal plate.

[0006] Furthermore, the number of the first mounting holes is at least two sets, making the mounting position of the current transformer relative to the horizontal plate adjustable.

[0007] Furthermore, the mounting plate includes a connecting section that is inclinedly connected between the horizontal plate and the vertical plate.

[0008] Furthermore, the mounting plate is integrally formed from sheet metal, and the horizontal plate, vertical plate and connecting section are formed by bending.

[0009] Furthermore, the horizontal plate, vertical plate, and connecting section each have flanges.

[0010] Furthermore, the rear door panel includes a first rear door panel and a second rear door panel arranged vertically, and the interval between the first rear door panel and the second rear door panel is flush with the horizontal plate.

[0011] Compared with the prior art, the switch cabinet with a suspended current transformer of this utility model has the following advantages: 1. This utility model of a switchgear features a mounting plate in the busbar compartment. The mounting plate includes a horizontal plate extending horizontally and a vertical plate perpendicular to the horizontal plate. The end of the horizontal plate away from the vertical plate is connected to a centrally extending partition, and the end of the vertical plate away from the horizontal plate is connected to a top plate. The current transformer includes an upper mounting surface that abuts against the lower surface of the horizontal plate, allowing the current transformer to be stably suspended inside the switchgear. This design provides ample space around the current transformer within the cabinet, enabling convenient connection by opening the rear door when connecting the busbar copper busbar to the current transformer. This significantly reduces installation time and provides a more efficient wiring method for the busbar copper busbar. Furthermore, this arrangement results in a compact cabinet structure, providing sufficient space for the cable compartment below and offering users more ample cable installation space.

[0012] 2. The vertically connected horizontal and vertical plates provide a stable foundation for the connection of the current transformers. At the same time, the vertical plates are provided with through slots, which correspond to the rear door panel. After opening the rear door panel, the operator can pass his hand through the through slots to connect and maintain the components in the busbar compartment, making the connection and maintenance more convenient.

[0013] 3. The number of first mounting holes of the current transformer is at least two sets, so that the mounting position of the current transformer relative to the horizontal plate is adjustable, thereby adapting to different busbars, and the position of the current transformer can be adjusted according to the actual situation to further optimize the layout of the cabinet.

[0014] 4. Compared with existing technologies, the current transformer does not need to be installed on the rear door panel, which makes the design of the rear door panel more flexible and eliminates the need to dedicate a separate rear door panel for the current transformer, thus saving costs.

In this embodiment, the fastener is a bolt. In this embodiment, there are at least two sets of first mounting holes 22, making the installation position of the current transformer 2 relative to the horizontal plate 11 adjustable. By aligning the second mounting hole 111 with the first mounting hole 22 to be connected and passing the bolt through the second mounting hole 111 and the first mounting hole 22, the installation position can be adjusted.

[0020] In this embodiment, the rear door panel 30 includes a first rear door panel 31 and a second rear door panel 32 arranged vertically, with the gap between the first rear door panel 31 and the second rear door panel 32 flush with the horizontal plate 11. The design of the rear door panel 30 is more flexible, eliminating the need for a separate rear door panel for the current transformer 2, thus saving costs.
