TECHNICAL FIELD
[0001] The utility model relates to transformer maintenance technical field, concretely is a multi -angle adjustable ground wire clamp. BACKGROUND
[0002] In the power system, the maintenance work of transformer and line is the important link of guaranteeing the safety and stability of power supply. However, the maintenance process has high safety risk to the staff, especially the electric shock risk. In the actual power maintenance scene, the transformer can be located in the outdoor substation, and the surrounding space is relatively open, but the equipment architecture is complex, and there are many connection points and different angle outgoing lines. The staff needs to maintain the transformer at different height and angle positions, such as when maintaining the sleeve on the top of the transformer or the busbar connection part on the side, the traditional ground wire clamp may not be able to well adapt to these complex angles. The line maintenance situation is more diverse, which may be operating on the overhead line on the tower, and the terrain around the tower is complex, which may be mountainous, hilly, etc., and the staff needs to operate at different cross arm positions of the tower. Moreover, the trend and angle of the overhead line are different, which requires the ground wire clamp to be flexible to adapt to these changes.
[0003] In the maintenance operation, the ground wire clamp is usually used to protect the safety of the staff. The traditional ground wire clamp has certain limitations in design. Most of the existing ground wire clamps are fixed structures, and the angle of the clamping part is not adjustable. In the complex field environment of transformer or line maintenance, due to the installation position, angle and surrounding space layout of the equipment and other factors, the staff may encounter many inconveniences when using the traditional ground wire clamp. For example, when the angle of the ground wire clamp does not match the operation position of the staff or the connection position of the maintenance equipment, the ground wire clamp may not be installed to the appropriate position smoothly, which not only affects the work efficiency, but also may cause the ground wire clamp to be not connected firmly or not connected properly. This situation will make the grounding wire unable to effectively play the protection role, so that the staff is exposed to the danger of electric shock in the maintenance process, which seriously threatens the life safety of the maintenance personnel and the stable operation of the power system. Therefore, it is urgent to provide a ground wire clamp that can solve the above problems to better protect the safety of the maintenance personnel in the maintenance process of transformer and line.
