Description

Technical Field

[0001] The present invention relates to the technical field of fixing copper stranded wires, and specifically to a fixing device and a using method for copper stranded wires at the top of a converter station valve hall. Background Art

[0002] In a high-voltage direct current (HVDC) transmission system, a converter station valve hall is one of the core facilities, and its main function is to achieve the conversion between alternating current and direct current. The copper stranded wires at the top of the valve hall, as key components for power transmission, undertake the task of conducting large currents;

[0003] However, in actual operation, the fixing clamps of the copper stranded wires are processed by each on-site construction unit. Therefore, the fixing methods of the copper stranded wire lightning protection brackets are slightly different, but the designed brackets basically use self-tapping screws to directly punch holes and fix on the color steel and keel. Since the color steel plate at the top of the converter station valve hall is relatively thin, the surface paint is very easy to be damaged and fall off, resulting in rust. If the construction unit does not fully consider before construction and directly punches holes for fixing, it will cause defects such as leakage on the color steel plate at the top of the valve hall, posing a major hidden danger to the internal equipment of the converter valve hall. At the same time, the copper stranded wires will generate electromagnetic vibration when transmitting large currents, especially under high load or short-circuit conditions, with a large vibration amplitude, which is likely to cause the fixing device to loosen or the connection to wear. Therefore, we propose a fixing device and a using method for copper stranded wires at the top of a converter station valve hall. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the existing defects, and provide a fixing device and a using method for copper stranded wires at the top of a converter station valve hall, which can avoid opening holes at the top of the converter station valve hall, and at the same time can buffer, reduce the looseness and wear of the copper stranded wires due to electromagnetic vibration, and can effectively solve the problems in the background art.

[0016] The usage method of the top copper stranded wire fixing device for the converter station valve hall according to any one of claims 1-9 includes the following steps:

[0017] S1: First, place two fastening blocks between the skeletons at the top of the converter station valve hall, and then rotate the bidirectional screw through the conical column on one side. The rotation of the bidirectional screw drives the two clamping frames to approach the skeletons at the top of the converter station valve hall. At this time, observe the positions of the two anti-slip plates. When they are in contact with the skeletons at the top of the converter station valve hall, stop rotating the conical column. At this time, the two fastening blocks will be pressed by the two third springs to tightly contact the skeletons at the top of the converter station valve hall through the two anti-slip plates. After the contact, the installation can be completed.

[0018] S2: After completion of installation, press the two pulling frames closer. The two pulling frames approaching drive the two clamping posts closer. At the same time, the two clamping posts separate from the connection holes and card slots connected thereto. After separation, rotate the turntable as required to make the copper stranded wire connection assembly rotate to adjust the inclination angle on its left and right. Then rotate the connection shaft to adjust the front and rear inclination angles of the copper stranded wire connection assembly. After adjustment, release the two pulling frames. At this time, the two clamping posts will move under the action of the first spring. After moving, the upper clamping post will pass through the corresponding connection hole and be clamped into the interior of the card hole opened on the lower side of the mounting frame, and the lower clamping post will be clamped into the interior of the corresponding card slot. In such a case, the turntable and the connection plate can be fixed respectively. After fixation, the angle adjustment of the copper stranded wire connection assembly can be completed;

[0019] S3: After the angle adjustment of the copper stranded wire connection assembly, remove the four bolts, and then the two arc-shaped plates separate. After separation, place the copper stranded wire to be installed into the interior of the two arc-shaped plates. After placement, use the four bolts to connect the two arc-shaped plates. After connection, the installation of the copper stranded wire can be completed;

[0020] S4: During the energization of the copper stranded wire after completion of installation, if vibration occurs, it will drive the slide bar to move. The slide bar moving drives the damping disc to move along the fixed housing. The damping disc moving can buffer the generated vibration.

[0021] Compared with the prior art, the beneficial effects of the present invention are: The copper stranded wire fixing device and the using method at the top of the valve hall of the converter station have the following advantages:

[0022] 1. By providing the fastening assembly and the clamping assembly, during use, the two fastening blocks can be placed between the skeletons at the top of the valve hall of the converter station. Then, the two-way screw is rotated by the tapered column on one side. The two-way screw rotating drives the two clamping frames closer to the skeletons at the top of the valve hall of the converter station. At this time, observe the positions of the two anti-slip plates. When they are in contact with the skeletons at the top of the valve hall of the converter station, stop rotating the tapered column. At this time, the two fastening blocks will be tightly in contact with the skeletons at the top of the valve hall of the converter station under the extrusion of the two third springs on the two anti-slip plates. After contact, the installation can be completed. After completion of installation, the two anti-slip plates can effectively prevent damage to the paint on the surface of the skeleton, thereby avoiding leakage at the top of the valve hall of the converter station;

[0023] 2. By setting the adjusting component and the clamping component, when in use, the turntable can be rotated according to requirements to make the copper stranded wire connecting component rotate and adjust the left - right tilt angle thereof. Then, by rotating the connecting shaft, the front - back tilt angle of the copper stranded wire connecting component can be adjusted. After adjustment, the two clamping posts will move under the action of the first spring. After moving, the upper clamping post will pass through the corresponding connecting hole and be clamped into the internal of the clamping hole opened on the lower side of the mounting frame, and the lower clamping post will be clamped into the internal of the corresponding clamping groove. In this case, the turntable and the connecting plate can be fixed respectively. After fixing, the angle adjustment of the copper stranded wire connecting component can be completed;

[0024] 3. By setting the buffer component and the copper stranded wire connecting component, after the angle of the copper stranded wire connecting component is adjusted, the copper stranded wire can be installed between the two arc - shaped plates. After installation, during the energization process of the copper stranded wire, if vibration occurs, it will drive the sliding rod to move. The movement of the sliding rod drives the damping disc to move along the fixed shell, and the movement of the damping disc can buffer the generated vibration, thereby reducing the loosening and wear of the copper stranded wire due to electromagnetic vibration;

[0025] 4. By setting the anti - slip component, after the positions of the two clamping frames are adjusted, the two anti - slip frames will move upward under the action of the four fourth springs to fix the two tapered columns. After fixing, the separation of the two anti - slip plates from the skeleton at the top of the converter station valve hall can be avoided. BRIEF DESCRIPTION OF THE DRAWINGS

A copper stranded wire fixing device and use method for the top of a converter station valve hall according to claim 6, characterized in that: An anti-slip plate (12) is fixed to the side of the fastening block (61), and evenly distributed anti-slip grooves are provided on the side of the anti-slip plate (12).

10. The method for using the copper stranded wire fixing device at the top of the converter station valve hall according to any one of claims 1 to 9, characterized in that: The following steps are involved: S1: First, place the two fastening blocks (61) between the skeleton at the top of the converter station valve hall, and then rotate the bidirectional screw (52) through the conical column (53) on one side. The rotation of the bidirectional screw (52) drives the two clamping frames (51) to approach the skeleton at the top of the converter station valve hall. At this time, observe the positions of the two anti-skid plates (12). When it fits with the skeleton at the top of the converter station valve hall, stop rotating the conical column (53). At this time, the two fastening blocks (61) will squeeze the two anti-skid plates (12) with the two third springs to fit tightly with the skeleton at the top of the converter station valve hall. After fitting, the installation is completed; S2: After the installation is completed, the two pulling frames (9) are pressed to move closer, and the two pulling frames (9) move closer to drive the two clamping columns (33) to move closer. At the same time, the two clamping columns (33) will be separated from the connecting holes (22) and the clamping slots (27) connected thereto. After separation, the turntable (21) is rotated as required to rotate the copper stranded wire connection assembly (8) to adjust its left and right tilt angles, and then the connecting shaft (25) is rotated to adjust the front and rear tilt angles of the copper stranded wire connection assembly (8). After adjustment, the two pulling frames (9) are released. At this time, the two clamping columns (33) will move under the action of the first spring (34). After movement, the clamping column (33) on the upper side will pass through the corresponding connecting hole (22) and be clamped into the inside of the clamping hole opened on the lower side of the installation frame (1), and the clamping column (33) on the lower side will be clamped into the inside of the corresponding clamping slot (27). In this case, the turntable (21) and the connecting plate (26) can be fixed respectively, and the angle adjustment of the copper stranded wire connection assembly (8) can be completed after fixing. S3: After adjusting the angle of the copper stranded wire connection assembly (8), the four bolts (82) are removed, and then the two arc-shaped plates (81) are separated. After separation, the copper stranded wire to be installed is placed inside the two arc-shaped plates (81). After placement, the two arc-shaped plates (81) are connected using four bolts (82). After connection, the installation of the copper stranded wire is completed; S4: After the installation is completed, if vibration is generated during the process of energizing the copper stranded wire, the sliding rod (62) will be driven to move, and the movement of the sliding rod (62) will drive the damping plate (43) to move along the fixed shell (41), and the movement of the damping plate (43) can buffer the generated vibration.
