Description

Technical Field

[0001] The utility model relates to the technical field of high-voltage cabinets, in particular to a combined high-voltage cabinet that is easy to maintain. Background Art

[0002] High-voltage cabinets are important power distribution equipment in power systems. They are composed of a cabinet body, an internal support frame, and several electronic components and modules. Currently, the electronic components and modules are installed inside the cabinet body. After the high-voltage cabinet has been used for a period of time, the internal electronic components and modules need to be maintained and repaired.

[0003] However, traditional maintenance and inspection requires opening the cabinet door and performing maintenance and inspection inside the cabinet. However, the space inside the cabinet is limited and the illumination is not strong. Therefore, it is more laborious to maintain and inspect the electronic components inside the existing high-voltage cabinet, and it is not possible to maintain and inspect efficiently and conveniently.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solutions: a combined high-voltage cabinet that is easy to maintain, including a high-voltage cabinet body, a first slide rail fixedly connected to both sides of the inner wall of the high-voltage cabinet body, a movable frame mechanism is provided on the inner side of the high-voltage cabinet body, the frame mechanism is matched with the first slide rail and slidably connected, the frame mechanism is slid out toward the back side of the high-voltage cabinet body, the upper and lower ends of the back side of the high-voltage cabinet body are fixedly connected with a second slide rail, a sealing plate is slidably connected to the second slide rail, and a lock is provided on the sealing plate.

[0006] Furthermore, the frame mechanism includes: a U-shaped frame, the ends of which are fixedly connected with sliders that slide in matching with the first slide rail, and the outer ends of the U-shaped frame are fixedly connected with baffles, which are arranged on the outside of the high-voltage cabinet.

[0007] Furthermore, heat dissipation holes are provided on both sides of the U-shaped frame, and the number of the heat dissipation holes is set in multiples and symmetrically distributed up and down.

[0008] Furthermore, a connecting plate is fixedly connected to the inner wall of the U-shaped frame between the heat dissipation holes, and the connecting plate is arranged in the middle position.

[0009] Furthermore, the upper and lower edges of the U-shaped frame located between the heat dissipation holes are provided with card slots, and the card slots are arranged in a U shape.

[0010] Furthermore, a sealing ring is fixedly connected to the periphery of the end of the U-shaped frame, and the sealing ring is arranged to abut against the interior of the high-voltage cabinet.

[0011] Furthermore, the sealing plates are symmetrically distributed on the second slide rail, and the locks are staggered and cross-arranged.

[0012] Compared with the above-mentioned background technology, the combined high-voltage cabinet that is easy to maintain provided by this application includes a high-voltage cabinet with very mature technology today, and a frame mechanism as the core component. Its principle relies on pulling out the U-shaped frame to the back side of the high-voltage cabinet body, and independently fixing and installing the electronic components and modules through the U-shaped frame. It can not only distinguish the electronic components and modules, but also increase the maintenance space and the illumination of the field of view.

The U-shaped frame independently separates the electronic components and modules, which is convenient for operation during maintenance and overhaul. The withdrawn U-shaped frame can increase the space for maintenance and overhaul and the brightness of the field of view, thereby facilitating maintenance of the high-voltage cabinet.

After the frame mechanism is pulled out, there is a larger operating space, and the light is better during maintenance and repair, which is convenient for maintenance and repair of the high-voltage cabinet.

[0022] like Figure 2 and Figure 3 As shown, the frame mechanism includes: a U-shaped frame 3, sliders 4 that slide with the first slide rail 2 and match the end of the U-shaped frame 3 are fixedly connected on both sides of the end thereof, and a baffle 9 is fixedly connected to the outer end of the U-shaped frame 3, and the baffle 9 is arranged on the outside of the high-voltage cabinet 1; the U-shaped frame 3 is surrounded on three sides to fix the electronic components and modules inside the U-shaped frame 3, and sliders 4 are fixedly connected to the ends of the U-shaped frame 3, which are stably supported for sliding and limiting on the first slide rail 2 by the sliders 4, and then a baffle 9 is fixed on the outside of the U-shaped frame 3, which not only facilitates the U-shaped frame 3 to be pulled outward, but also increases the sealing effect between the U-shaped frame 3 and the high-voltage cabinet 1, thereby reducing the entry of external dust into the interior.
