Description

Technical Field

[0001] This utility model relates to a live plug-in mechanism for a busbar plug-in box, specifically a live plug-in mechanism for a secondary power distribution busbar plug-in box in the electrical industry. Background Technology

[0002] In the electrical industry, secondary power distribution busbars need to be energized and plugged into connection boxes. In existing technology, the installation method for energized plug-in boxes for busbar trunking is generally as follows: 1) Mark the installation position of the connection box according to the design drawings, ensuring alignment with the busbar trunking socket; 2) Open the protective cover of the busbar trunking socket; 3) Align the pins of the connection box with the busbar trunking socket, insert it manually, and tighten it with a torque wrench; 4) Confirm that the connection box and busbar trunking are in tight contact and there is no looseness.

[0003] However, the existing installation methods are imperfect and cannot guarantee that the plug-in box and the busbar trunking plug interface are completely aligned. Relying solely on manual visual inspection and past experience for live plugging and unplugging is highly susceptible to unstable factors such as personnel and environment, which can cause busbar short circuits during live plugging and unplugging, resulting in serious consequences. Utility Model Content

[0004] This utility model proposes a live plug-in mechanism for busbar plug-in boxes, which aims to overcome the above-mentioned shortcomings of the existing technology, improve the stability of live plug-in between the plug-in box and the busbar trunking, avoid short circuit accidents, and is suitable for high-density busbar live plug-in plug-in boxes.

[0005] The technical solution of this utility model is as follows: A live plug-in mechanism for a busbar plug-in box, comprising a plug-in box body, a busbar body, a fixed bracket, a movable bracket, a platform plate, and a lateral movement mechanism. The busbar body is fixed between one side of the fixed bracket and the movable bracket, with the movable bracket connected below one side of the fixed bracket. The plug-in box body is fixed on the platform plate, which is mounted on the lateral movement mechanism, which is mounted on the other side of the fixed bracket. In use, the busbar body is first fixed using the movable and fixed brackets. Then, the plug-in box body is placed on the platform plate, initially aligning the plug-in interface of the plug-in box body with the plug-in interface of the busbar body. The height of the plug-in box body is then adjusted to align its interface with the busbar body interface both horizontally and vertically. The lateral movement mechanism then moves the platform plate laterally, thereby moving the plug-in box body towards the busbar body until it is inserted into the designated position on the busbar body. Once the plug-in box body is confirmed to be in place, it is fixed. The mechanism is then removed, and finally, the torque bolts on the plug-in interfaces are loosened.

[0006] Preferably, the fixed bracket includes a support frame, pillars, diagonal braces, and fixed rods. One side of the support frame is connected to the bottom of the pillars. The tops of the two pillars are each connected to one end of a fixed rod. The ends of the two fixed rods are each vertically connected to the top of a lead screw. The bottoms of the two pairs of lead screws are each connected to the ends of a movable bracket. An adjusting nut is screwed onto the lead screw below the movable bracket. A diagonal brace connects the top side of the fixed rod to the support frame. After the busbar body is placed between the fixed rod and the movable bracket, adjusting the adjusting nut brings the movable bracket closer to the fixed rod, thus fixing the busbar body.

[0007] Preferably, the platform plate is provided with four limiting plates, and the plug-in box body is fixed on the top surface of the platform plate between the four limiting plates. A height adjustment rod is connected between the platform plate and the lateral moving mechanism, with the top end of the height adjustment rod connected to the platform plate and the bottom end connected to the lateral moving mechanism. The height of the plug-in box body can be adjusted by driving the platform plate to rise and fall vertically through the height adjustment rod.

[0008] Preferably, the lateral movement mechanism includes a movable support, a rotary handle, a lead screw and nut assembly, and cylindrical guide rails. The lead screw and nut assembly is installed in the middle of the support frame and one end is connected to the rotary handle. Cylindrical guide rails are provided on the support frames on both sides of the lead screw and nut assembly. The nut of the lead screw and nut assembly and the slider of the cylindrical guide rails are fixed to the bottom of the movable support. The lower end of the height adjustment rod is connected to the movable support. Rotating the rotary handle can drive the movable support to move laterally through the lead screw and nut assembly. The cylindrical guide rails are used for auxiliary guidance, thereby driving the plug-in box body on the platform plate to move laterally relative to the busbar body.

[0009] Advantages of this utility model: 1) Stable structure. It is reliably fixed to the busbar by the bracket, which can effectively ensure that the busbar slot interface and the plug box interface are on the same horizontal line. It is not affected by external force and environmental factors during the transmission process, thus ensuring the safety of live plugging and unplugging.

[0010] 2) It can prevent injury to installation personnel from short circuit accidents caused by plugging and unplugging the busbar junction box while it is energized.

[0011] 3) It is simple to produce, has low cost, and is easy to install. Attached Figure Description
