Description

Technical Field

[0001] This invention relates to the field of special tools technology, and more specifically, to a wire splicing and disconnecting device. Background Technology

[0002] Pre-testing of electrical equipment requires disconnecting the equipment's leads to ensure insulation and prevent interference with test results. This is especially true for tests on transformers, such as FDS and winding deformation tests, which necessitate disconnecting the transformer leads before the tests can be conducted.

[0003] As the diameter of transformer leads increases with voltage levels, so does their weight; a 500kV transformer lead can weigh over 100 kilograms. Furthermore, the lead connection plate is located at a high position, sometimes reaching heights of over ten meters for a 500kV transformer. This makes connecting and disconnecting the leads extremely difficult.

[0004] The existing method of wire splicing involves using a crane to traction and pull the wires, while manual splicing is performed using a wrench on the moving and stationary contacts. After splicing, the wires must be secured with insulating tape or ropes to hold the bushing lugs to prevent the wires from swinging and damaging the bushing insulator. This method is physically demanding and carries significant risks. Summary of the Invention

[0005] This invention provides a wire splicing and disconnecting device to solve the problem of high labor intensity and high risk in manual wire splicing and disconnecting operations in related technologies.

[0006] This invention provides a wire splicing and disconnecting device, comprising: a fixed base having a device connection part, a rotating shaft being provided on the fixed base, the rotating shaft being rotatably arranged around its own axis, an insulating rope being wound on the rotating shaft, and a connector for connecting a moving contact being provided at the end of the insulating rope; and an isolation base being spaced apart from the fixed base, the isolation base having a stationary contact connection part, the insulating rope being laid on the isolation base and crossing the isolation base, and the connector and the rotating shaft being located on opposite sides of the isolation base.

[0007] Furthermore, the isolating seat includes a seat frame and an adjusting member, which is movably mounted on the seat frame to adjust the relative position of the seat frame and the stationary contact, and the insulating rope is laid on the isolating seat.

[0008] Furthermore, the adjusting component includes an adjusting bolt, and the seat frame has a threaded hole, through which the adjusting bolt is adjusted in length.

[0009] Furthermore, the seat frame includes a bearing section and support sections connected to both ends of the bearing section respectively. An insulating rope is laid on the bearing section. The two support sections are located on both sides of the stationary contact. There are two adjusting members, which are movably set on the corresponding support sections. The two adjusting members together form the stationary contact connection part.

[0010] Furthermore, the wire disconnection device also includes a buffer member movably mounted on the isolation seat, the extension direction of the buffer member having an angle with the extension direction of the insulating rope, the end of the buffer member being connected to the isolation seat, and the insulating rope being threaded through the buffer member.

[0011] Furthermore, the buffer includes a first spring, a connecting ring, and a second spring connected in sequence. Both the first spring and the second spring are connected to the isolation seat, and the insulating rope passes through the connecting ring.

[0012] Furthermore, the wire disconnection device also includes an alarm and a tension sensor capable of detecting the tension of the insulating rope, with the alarm and the tension sensor connected by a signal connection.

[0013] Furthermore, the fixed base is also equipped with a stopper that can prevent the rotation of the shaft.

[0014] Furthermore, the wire splicing device also includes a meshing drive wheel and a transmission wheel. The drive wheel is rotatably mounted on a fixed base, and the transmission wheel is sleeved on a rotating shaft. The diameter of the drive wheel is larger than that of the transmission wheel, and the anti-rotation component is engaged with the transmission wheel to prevent rotation.

[0015] Furthermore, the equipment connection includes a first clamp; and / or, the connector includes a second clamp that is engaged with the moving contact.

[0016] The conductor splicing / disconnecting device of this invention includes a fixed base and an isolating base. The fixed base is connected to the power equipment via an equipment connection part, and the isolating base is connected to the stationary contact via a stationary contact connection part. An insulating rope wound on a rotating shaft is laid on and across the isolating base. A connector at the end of the insulating rope is used to connect the moving contact. When disassembling the conductor, the moving and stationary contacts are separated. The insulating rope is used to pull the moving contact and the conductor. By rotating the rotating shaft and gradually extending the insulating rope, the conductor descends slowly, thus preventing disorderly swaying of the conductor and avoiding damage to the bushing insulator. When installing the conductor, simply rotating the rotating shaft and gradually winding the insulating rope allows the conductor to be slowly retrieved, preventing disorderly swaying of the conductor and avoiding damage to the bushing insulator. Furthermore, compared to manually pulling the conductor with a crane, this method reduces labor intensity and operational risks. Attached Figure Description

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] like Figures 1 to 3 As shown, this embodiment of the invention provides a wire splicing device, which includes a fixed base 10 and an isolation base 20. The fixed base 10 has a device connection part 11 and a rotating shaft 12 is provided on the fixed base 10. The rotating shaft 12 is rotatably arranged around its own axis. An insulating rope 13 is wound on the rotating shaft 12, and a connector 14 for connecting a moving contact 41 is provided at the end of the insulating rope 13. The isolation base 20 is spaced apart from the fixed base 10. The isolation base 20 has a stationary contact connection part 21. The insulating rope 13 is laid on the isolation base 20 and crosses the isolation base 20. The connector 14 and the rotating shaft 12 are respectively located on both sides of the isolation base 20.

[0028] According to the technical solution of this invention, the conductor splicing and disconnecting device includes a fixed base 10 and an isolation base 20. The fixed base 10 is connected to the power equipment via the equipment connection part 11, and the isolation base 20 is connected to the stationary contact 40 via the stationary contact connection part 21. The insulating rope 13 wound on the rotating shaft 12 is laid on the isolation base 20 and crosses the isolation base 20. The moving contact 41 is connected by the connector 14 provided at the end of the insulating rope 13. When disassembling the conductor, the moving contact 41 and the stationary contact 40 are separated. The moving contact 41 and the conductor are pulled by the insulating rope 13. By rotating the rotating shaft 12 and gradually extending the insulating rope 13, the conductor is slowly lowered, thereby avoiding disorderly swinging of the conductor and preventing damage to the bushing insulator. When installing the conductor, it is only necessary to rotate the rotating shaft 12 and gradually wind up the insulating rope 13 to slowly retract the conductor, thereby avoiding disorderly swinging of the conductor and preventing damage to the bushing insulator. Furthermore, compared to the method of manually pulling the cable with a crane, this method reduces the workload and minimizes operational risks.

[0029] In this embodiment, the stationary contact 40 is disposed at the upper end of the sleeve, and the moving contact 41 is connected to the wire. After the moving contact 41 and the stationary contact 40 are connected, they can form a conductive path.

[0030] The isolating seat 20 is located above the fixed seat 10. The isolating seat 20 can isolate the insulating rope 13 and the stationary contact 40.

[0031] Specifically, when the insulating rope 13 is at a right angle to the moving contact 41, it can ensure that the moving contact 41 and the stationary contact 40 are aligned, which facilitates connection.

[0032] In this embodiment, the insulating rope 13 is 0.5m long and has a wire diameter of less than 3mm to reduce the volume of the shaft. It has a load-bearing capacity of 100kg, an insulation resistance greater than 10GΩ, a voltage drop of less than 0.0005 ohms under 10kV voltage, and can withstand AC 50kV withstand voltage. It can be made of PE material, which has good insulation and mechanical properties.

[0033] like Figure 1 As shown, the isolating seat 20 includes a seat frame 22 and an adjusting member 23. The adjusting member 23 is movably disposed on the seat frame 22 to adjust the relative position of the seat frame 22 and the stationary contact 40. The insulating rope 13 is laid on the isolating seat 20. With the above structure, by adjusting the position of the adjusting member 23 on the seat frame 22, the relative position of the seat frame 22 and the stationary contact 40 can be adjusted to facilitate the laying of the insulating rope 13.

[0034] The adjusting element 23 can be one or more. When there is only one adjusting element 23, it can be used in conjunction with a spring, with the adjusting element 23 and the spring respectively set on both sides of the stationary contact 40.

[0035] like Figure 1As shown, the adjusting component 23 includes an adjusting bolt, and the seat frame 22 has a threaded hole. The adjusting bolt is adjusted in length through the bolt hole. Using the adjusting bolt to adjust the position of the seat frame 22 has the advantages of simple structure and easy operation.

[0036] like Figure 1 As shown, the seat frame 22 includes a bearing section 221 and support sections 222 connected to both ends of the bearing section 221. An insulating rope 13 is laid on the bearing section 221. The two support sections 222 are located on both sides of the stationary contact 40. Two adjusting members 23 are movably disposed on their respective support sections 222, and together they form the stationary contact connection portion 21. The seat frame 22 with the above structure has the advantages of simple structure and ease of processing.

[0037] like Figure 3 As shown, the wire disconnection device also includes a buffer member 30 movably mounted on the isolation seat 20. The extension direction of the buffer member 30 forms an angle with the extension direction of the insulating rope 13. The end of the buffer member 30 is connected to the isolation seat 20, and the insulating rope 13 passes through the buffer member 30. The buffer member 30 can provide a buffering force for the insulating rope 13. When the wire shakes due to external force and causes the insulating rope 13 to shake, the buffering force provided by the buffer member 30 can reduce the shaking amplitude of the insulating rope 13.

[0038] The buffer component 30 can be a spring or other hydraulic components with buffering function.

[0039] like Figure 3 As shown, the buffer 30 includes a first spring 31, a connecting ring 32, and a second spring 33 connected in sequence. Both the first spring 31 and the second spring 33 are connected to the isolation seat 20, and the insulating rope 13 passes through the connecting ring 32. The buffer 30 with the above structure has the advantages of simple structure and easy installation.

[0040] In other embodiments, only one spring may be provided, with one end of the spring connected to the isolation seat 20 and the other end provided with a connecting ring 32.

[0041] The wire disconnection device also includes an alarm and a tension sensor capable of detecting the tension of the insulating rope 13. The alarm and the tension sensor are connected by a signal connection. The tension sensor detects the tension of the insulating rope 13 and transmits the detection signal to the alarm, thereby alerting the operator so that the operator can take appropriate measures.

[0042] In this embodiment, the tension sensor is mounted on the insulating rope 13 or the connector 14.

[0043] Specifically, the mounting base 10 is also equipped with an anti-rotation component that can prevent the rotation of the shaft 12. By controlling the rotation state of the shaft 12 using the anti-rotation component, the length of the insulating rope 13 can be controlled, thereby controlling the position of the conductor.

[0044] The wire splicing device also includes a meshing drive wheel and a transmission wheel. The drive wheel is rotatably mounted on the fixed base 10, and the transmission wheel is sleeved on the rotating shaft 12. The diameter of the drive wheel is larger than that of the transmission wheel, and an anti-rotation component is engaged with the transmission wheel. By utilizing gear transmission, the driving force of the drive wheel can be converted into the rotational power of the rotating shaft, and the transmission wheel can have a faster rotational speed, thereby achieving the purpose of saving effort.

[0045] In this embodiment, the anti-rotation element is an anti-rotation disc rotatably mounted on the fixed base 10, and the anti-rotation disc has multiple anti-rotation grooves that can mesh with the teeth of the transmission wheel. By rotating the anti-rotation disc, an anti-rotation engagement can be formed with the transmission wheel. By separating the anti-rotation disc from the transmission wheel, the transmission wheel can rotate freely.

[0046] The drive shaft of the drive wheel is fitted with an operable crank. The crank can be removed, and the connection between the crank and the drive shaft is set as a connector that can be connected to a ratchet wrench or an electric wrench. It can be used with a ratchet wrench or an electric wrench for cable winding and unwinding, which is more labor-saving and faster.

[0047] like Figure 1 As shown, the equipment connection part 11 includes a first clamp, which is used to connect the fixing seat 10 to the power equipment, and has the advantage of simple structure.

[0048] In this embodiment, the tension sensor is disposed between the first clamp and the insulating rope 13.

[0049] In this embodiment, the connector 14 includes a second clamp that is engaged with the moving contact 41.
