Description

Technical Field

[0001] The utility model belongs to the technical field related to power transmission and distribution equipment, and specifically relates to a magnetic coupling clamp for power transmission lines. Background Art

[0002] When installing ancillary facilities (such as lightning arresters) on live transmission line towers, operators need to secure the transmission line conductors to the ancillary facilities with a connecting wire clamp. For compact transmission line towers such as 35kV, 110kV, and some 220kV, live working clearances do not meet safety distance requirements, making them unsuitable for equipotential work and requiring ground potential work. Existing connecting wire clamps, due to their large number of components, lead to a series of problems such as cumbersome installation, the need for a large number of auxiliary personnel and related installation equipment, low daily workload, and high operating expenses, making them unsuitable for ground potential work. The transmission line-specific magnetic connecting wire clamp proposed in patent CN201811061438.5, when used, requires the operator to insert the transmission wire through the gap, then assemble the first and second bodies, with the first and second magnetic parts engaging with each other to ensure secure adsorption. This magnetic coupling clamp has a simple structure, requires minimal installation tools, and is easy to install. It is suitable for ground potential operations and overcomes the shortcomings of existing coupling clamps, improving installation efficiency and significantly saving installation equipment and personnel costs. While this patent meets the requirements to a certain extent, in actual use, it was found that this design requires reaching the transmission conductor before installation. For some larger transmission towers, to ensure equipment safety, the span between the two transmission conductors is often set a certain distance, requiring workers to climb to move their work position, which is time-consuming and labor-intensive, leaving room for improvement in practicality.

[0003] In view of this, the present utility model is proposed. Utility Model Content

The main half clamp 1 and the auxiliary half clamp 4 play the role of stable support, the hinge seat 2 and the hinge frame 3 play the role of rotational connection, the magnetic plate 25 and the electromagnetic coil 26 facilitate the locking of the device, and the three-stage rod 8, the secondary rod 9 and the rod body 10 facilitate the extension and retraction of the rod.

[0025] Among them, a control box 11 is fixedly connected to one side of the rod body 10, a signal generator 19 is provided on the control box 11, and a signal receiver 32 is provided on the control box 13. The control box 11 facilitates human-computer interaction, and the signal generator 19 and the signal receiver 32 facilitate wireless signal transmission.

Both the main half-sleeve 14 and the secondary half-sleeve 5 are of semi-circular design and made of the same material. The main half-sleeve 14 and the secondary half-sleeve 5 play a role in guiding current. The above design facilitates conductive operation.

[0027] A process table 15 is integrally formed on the main half sleeve 14, and a mounting hole 16 is drilled on the process table 15. A main fixing screw 17 is threadedly connected to the mounting hole 16, and a main line connector 18 is sleeved on the main fixing screw 17. A connecting main line 12 is provided between the two main line connectors 18. The process table 15 facilitates the fixed connection of the main line connector 18.

The device is started by the control box 13, and the electromagnetic coil 26 is energized, and the main half clamp 1 and the auxiliary half clamp 4 are locked by magnetic attraction.

The signal generator 19 sends a signal and is received by the signal receiver 32. Then, the control board 30 controls the relay 28 to energize the electromagnetic coil 26, and the secondary half clamp is locked by magnetic attraction. 4, then, the pole body 10 is fixed to the appropriate position of the transmission tower, and the construction operation can be carried out. During the magnetic locking process of the electromagnetic coil 26, the displacement switch 33 is always triggered by the magnetic bracket 6. If the secondary half clamp 4 is not locked in place, the displacement switch 33 transmits a signal to the control box 13, and the control box 13 issues an alarm to remind the staff to check. The new structure of the present invention is reasonable in design and easy to install and use. Through the design of the main half clamp 1, the secondary half clamp 4, the magnetic seat 7, the magnetic bracket 6, the hanging groove 34, the third rod 8, the second rod 9 and the pole body 10, not only can the telescopic rod be remotely controlled to connect the transmission line, but also the main half clamp 1 and the secondary half clamp 4 can be fixed by electromagnetic attraction, which greatly improves the construction effect and has good practicality and economy. Through the design of the protective resistor 29 and the displacement switch 33, not only can the electromagnetic coil 26 be discharged to protect it, thereby reducing the failure rate of the device, but also whether the main half clamp 1 and the secondary half clamp 4 are closed can be detected, thereby improving the safety of the device.
