Description

Technical Field

[0001] This utility model belongs to the field of DCS cabinet antistatic floor grounding technology, and particularly relates to a DCS cabinet antistatic floor grounding tool. Background Technology

[0002] The existing DCS cabinet room has been in use for over 20 years. Due to limitations in the technical standards at the time, anti-static grounding measures were not mandatory during infrastructure construction. Therefore, no dedicated grounding copper strip was laid under the anti-static floor supports of the original cabinet room, and no effective anti-static grounding network was established. In recent years, with the updating of safety standards such as the "Instrument System Grounding Design Code" (HG / T20513-2014) Article 3.4.1, which stipulates that control rooms, cabinet rooms, and computer rooms for process control systems and other equipment should be equipped with anti-static grounding, and that conductive floors, anti-static raised floors, workbenches, etc., in these rooms should be grounded, the technical requirements for anti-static grounding in DCS cabinet rooms have been clearly defined. Enterprises need to carry out compliance rectification of old cabinet rooms to eliminate safety hazards such as fires and signal interference caused by static electricity accumulation. Summary of the Invention

[0003] The purpose of this utility model is to provide a grounding tool for anti-static flooring in DCS cabinet rooms to solve the problems existing in the prior art.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A grounding tool for an anti-static floor in a DCS cabinet room includes an anti-static floor bracket and a main static grounding busbar for the cabinet room. Several anti-static floor brackets are connected via an anti-static network. The anti-static network includes several anti-static units, each consisting of several first grounding clamps connected in series via grounding wires. Each anti-static floor bracket holds two first grounding clamps, which originate from two different anti-static units. At least two anti-static floor brackets hold second grounding clamps, which are connected to redundant access points of the main static grounding busbar for the cabinet room via grounding wires.

[0006] Furthermore, the grounding clamp is a fully enclosed copper-plated tape insulating sleeve D-type clamp with a nominal current carrying capacity of 200A, a grounding wire opening size of 30mm, and a clamp handle with double-ended wiring holes, supporting quick connection of the grounding wire.

[0007] Furthermore, the grounding wire is a yellow-green bicolor BVR 2.5mm². 2 The length of the grounding wire connecting the two first grounding clamps is 750mm.

[0008] This utility model has the following beneficial effects:

[0009] 1. This utility model is used to renovate old DCS cabinets, and can establish an effective anti-static grounding network without the need for grounding copper strips.

[0010] 2. No DCS cabinet shutdown is required during installation, reducing the risk of retrofitting old DCS cabinets.

[0011] 3. Two anti-static units are connected to one anti-static floor bracket, which can meet the requirement of expansion length of 10 meters, and the length of the anti-static units can be configured arbitrarily as needed to flexibly adapt to different rack layouts.

[0012] 4. It is compatible with over 90% of anti-static floor supports on the market, offering strong compatibility.

[0013] 5. Compared to the traditional copper strip method, material costs are reduced by 40%.

[0014] 6. The first grounding clamp 1 and the second grounding clamp 7 can be quickly replaced in case of failure without affecting the overall grounding network. Attached Figure Description

[0015] Figure 1 This is a schematic diagram of the structure of this utility model.

[0016] Figure 2 This is a schematic diagram of the antistatic network structure of this utility model.

[0017] The components include: 1. First grounding clamp; 2. Anti-static network; 3. Anti-static floor support; 4. Grounding wire; 5. Main static grounding busbar between cabinets; 6. Anti-static unit; 7. Second grounding clamp; 8. Redundant access point. Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with specific embodiments and accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the scope of the utility model.

[0019] like Figure 1-2 As shown, a grounding tool for anti-static floor in a DCS cabinet room includes an anti-static floor bracket 3 and a main static grounding busbar 5 for the cabinet room.

[0020] The commonly used room dimensions for DCS (Distributed Control System) server racks are:

[0021] Small (4-8 rack): 6.0m × 3.0m × 3.0m;

[0022] Medium-sized (10-20 racks): 8.0m × 4.0m × 3.2m;

[0023] Large (30+ racks): 12.0m × 8.0m × 3.5m.

[0024] Each DCS cabinet is equipped with an anti-static floor bracket 3, meaning the number of anti-static floor brackets 3 matches the number of DCS cabinets. The anti-static floor brackets 3 are connected through an anti-static network 2, which includes several anti-static units 6. Each anti-static unit 6 is composed of several first grounding clamps 1 connected in series via grounding wires 4. Each anti-static floor bracket 3 holds two first grounding clamps 1, which come from two different anti-static units 6. At least two anti-static floor brackets 3 hold second grounding clamps 7, which are connected to the redundant access point 8 of the main static grounding busbar 5 between cabinets via grounding wires 4.

[0025] The grounding clamp is a D-type clamp with a fully enclosed copper-plated insulating sleeve. The nominal current carrying capacity of the grounding clamp is 200A, the opening size of the grounding wire 4 is 30mm, the clamp handle has double-ended wiring holes, and the grounding clamp supports quick connection of the grounding wire 4.

[0026] Grounding wire 4 is a yellow-green bicolor BVR 2.5mm² wire. 2 A multi-strand flexible wire, the grounding wire 4 connecting the two first grounding clamps 1 has a length of 750mm.

[0027] The working principle of this utility model is as follows:

[0028] All anti-static floor brackets 3 are connected and covered by an anti-static network 2, and then connected to the redundant access point 8 of the main static grounding busbar 5 in the server room via a second grounding clamp 7 and a grounding wire 4, thus forming a redundant grounding path. The double-ended wiring structure of the first grounding clamp 1 and the second grounding clamp 7 achieves series connection and electrical isolation of the grounding wire 4, avoiding grounding loops. The 750mm spacing of the grounding wires 4 balances grounding efficiency and construction efficiency. At least two anti-static floor brackets 3 are connected to the main static grounding busbar 5 in the server room via the second grounding clamp 7 and the grounding wire 4, ensuring anti-static connection even if one grounding wire 4 is broken, improving system reliability. Installation does not require DCS cabinet shutdown, reducing the risk of retrofitting old DCS cabinets. Two anti-static units 6 are connected to one anti-static floor bracket 3, meeting the requirement of a 10-meter expansion length, and the length of the anti-static unit 6 can be arbitrarily configured to flexibly adapt to different server room layouts. It is applicable to more than 90% of anti-static floor brackets on the market, with strong compatibility. Compared with the traditional copper strip method, material costs are reduced by 40%. The first grounding clamp 1 and the second grounding clamp 7 can be quickly replaced in case of failure without affecting the overall grounding network.

Various modifications and improvements made to the technical solutions of the present invention by those skilled in the art without departing from the design concept of the present invention should fall within the protection scope of the present invention.
