Description

Technical Field

[0001] This invention relates to the field of power transmission line de-icing technology, and in particular to a cable-stayed series-type power take-off device for an automatic ground wire de-icing connection device. Background Technology

[0002] During the cold winter, some power transmission lines in southern my country are prone to icing. Unlike jumpers, overhead ground wires cannot resist some freezing through the heat generated by the load current, and the ice thickness on them is generally much greater than that on jumpers. Severe icing on ground wires can lead to power grid accidents. The installation of automatic ground wire de-icing connection devices effectively solves the problem of icing on the surface of ground wires.

[0003] As the number of automatic grounding de-icing connection devices increases, the types of tower-type and jumper string-type installation devices are also gradually increasing. This paper presents a diagonal string-type power supply for an automatic grounding de-icing connection device designed for a double-split jumper string.

[0004] In the prior art, CN 218549461 U describes an automatic wiring device for de-icing of a inclined string ground wire. The structures are not entirely the same. The contact finger structure is relatively simple, which cannot maintain the stability of the spatial position. The non-adjustable contact finger structure cannot guarantee that the device can close correctly. Summary of the Invention

[0005] The purpose of this invention is to provide a tie-down string type power take-off device for an automatic ground wire de-icing connection device, which is installed on the jumper string without changing the original jumper suspension clamp connection, and is connected to two tie-down strings to maintain the stability of its spatial position, thereby ensuring that the device can be closed correctly.

[0006] To achieve the above objectives, the present invention provides a diagonal-type power collector for an automatic grounding wire de-icing connection device, comprising a jumper suspension clamp, a connecting suspension plate, a C-shaped support frame, a contact finger current-passing assembly, a figure-eight plate, and a drain clamp. The jumper suspension clamp connects to the jumper string. The connecting suspension plate is installed around the jumper suspension clamp, with the upper end connected to the jumper string and the lower end connected to the C-shaped support frame. A vertical connecting plate is provided on the side of the central position of the C-shaped support frame body. The contact finger current-passing assembly is installed on the vertical connecting plate. A set of figure-eight plates are symmetrically arranged on both sides of the C-shaped support frame, and the figure-eight plates are respectively connected to the diagonal-type power collector. The current-passing connecting plate of the contact finger current-passing assembly is connected to the drain plate of the drain clamp, and the other end of the drain clamp grips the jumper.

[0007] It also includes counterweights, which are set on both sides of the C-shaped support frame.

[0008] The jumper suspension clamp is a double-split jumper suspension clamp.

[0009] The connecting suspension plates are symmetrically arranged on the left and right sides and installed around the jumper suspension clamps. At least one support sleeve is installed in the middle of the connecting suspension plates.

[0010] The C-shaped support frame has two holes in the center of its main body for connection and fixation with the connecting suspension plate, and a vertical connecting plate is designed on its side to connect to the contact finger flow assembly.

[0011] The contact finger current-carrying assembly includes a contact finger assembly, a guide component, a protective component, and a current-carrying connecting plate. The current-carrying connecting plate is an aluminum alloy connecting plate. The guide component and the protective component are arranged around the contact finger assembly for guidance and protection. One side of the current-carrying connecting plate is fixedly connected to the contact finger assembly to conduct current, and the other side is connected to the current-carrying plate of the current-carrying clamp. An adjustment hole is designed in the middle of the current-carrying connecting plate. The center line of the adjustment hole makes an angle θ with the vertical direction. The angle θ is adjustable.

[0012] The vertical connecting plate on the C-shaped support frame has connecting holes that are fixedly connected to the mounting and adjustment holes on the flow-through connecting plate.

[0013] The figure-eight plates are installed on the connecting plates on both sides of the C-shaped support frame, forming a figure-eight shape. The connecting holes on the outward-flaring sides of the figure-eight plates are adjustable in position to connect with the diagonal tie rods. Depending on the needs, the connecting holes of the figure-eight plates can be installed at the top or bottom to increase the electrical distance of the power take-off device.

[0014] The current-carrying clamp grips the jumper wire, conducting the current to the contact finger current-carrying assembly mounted on the C-type support frame, and then conducting it outwards through the contact finger structure. The jumper wire suspension clamp and connecting suspension plate are mounted together on the connecting hardware of the jumper wire string. The C-type support plate is connected to the connecting suspension plate, and the contact finger current-carrying assembly is mounted on the vertical connecting plate of the C-type support plate, with the center of gravity closer to the tower body. Counterweight plates are mounted on the connecting plates on both sides of the C-type support frame, with the overall center of gravity on the contact finger current-carrying assembly side. The C-type support frame is connected to the inclined tie rod string via a figure-eight plate, ensuring the inclined tie rod string is always under tension, guaranteeing the stability of the inclined tie rod string type power take-off position, and better enabling the correct closing of the automatic ground wire de-icing wiring device.

[0015] The jumper suspension clamp is a double-split jumper suspension clamp that can be modified according to the jumper structure. In order to reduce the height of the jumper suspension clamp, the height of the connecting suspension plate can be reduced.

[0016] The connecting suspension plate is positioned around the jumper suspension clamp and is mounted on the jumper string's connecting hardware using the same set of bolts. The lower end of the connecting suspension plate connects to the middle of the C-shaped support frame, providing a suspension function. A support sleeve is designed in the middle to maintain the relative position of the two suspension plates when subjected to external forces, ensuring the jumper suspension clamp can swing freely along the line direction.

[0017] The contact finger current collector mainly consists of a contact finger assembly, guide components, protective components, and an aluminum alloy connecting plate. The guide components and protective components are arranged around the contact finger assembly for guidance and protection. One side of the aluminum alloy plate is welded to the contact finger assembly to conduct current, while the other side connects to the current-carrying plate of the current-carrying clamp. An adjustment hole is designed in the middle of the aluminum alloy plate, and the center line connecting the adjustment holes forms an angle θ with the vertical direction. When the current collector is installed, the angle can be adjusted by ±α°.

[0018] Two holes in the center of the C-shaped support frame are connected and fixed to the connecting suspension plate. A connecting plate is designed on its side to install the contact finger current flow assembly. The connecting plates on both sides of the C-shaped support frame are spaced apart to ensure that they do not interfere with the contact finger current flow assembly in the middle after the counterweight is installed.

[0019] On the connecting plates on both sides of the C-shaped support frame, a set of figure-eight plates are installed, forming a figure-eight shape. The connecting holes on the outward-flaring sides of the figure-eight plates connect to the diagonal tie rods. Depending on the actual needs of the site, the connecting holes of the figure-eight plates can be installed at the top or the bottom to increase the electrical distance of the power take-off device.

[0020] Several counterweight plates are installed on the connecting plates on both sides of the C-shaped support frame, so that the center of gravity of the power collector is closer to the tower body, thereby subjecting the cable tie string to tension.

[0021] The number of drain clamps is the same as the number of jumpers. One end of the drain clamp holds the jumper and the other end is connected to the touch drain assembly. The middle end is a stranded wire that carries current to achieve the function of current conduction.

[0022] A type of inclined pulley series current collector for an automatic ground wire de-icing connection device is part of the automatic ground wire de-icing connection device. Its function is to connect one end to the jumper for overcurrent and the other end to the opening and closing conductor of the automatic ground wire de-icing connection device to close the circuit and realize the conduction of current.

[0023] Beneficial effects: This invention connects the suspension plate to the periphery of the jumper suspension clamp, and the two are installed together on the jumper string. The current clamp grips the jumper, conducting the current to the contact finger current-carrying assembly installed on the C-shaped support frame and then conducting it out through the contact finger structure. Counterweight plates are installed on the connecting plates on both sides of the C-shaped support frame, with the overall center of gravity on the contact finger current-carrying assembly side. The overall angle of the contact finger current-carrying assembly is adjustable. It is connected to the inclined tie string via a figure-eight plate, ensuring the inclined tie string is always under tension, guaranteeing the stability of the inclined tie string type power take-off position, and thus better enabling the correct closing of the automatic grounding de-icing wiring device.

[0024] This structure does not change the original jumper suspension clamp connection method. The designed inclined pull string power supply can be directly installed on the jumper string. The eccentric counterweight design and the inclined pull string connection design ensure the stability of the power supply's spatial position. Attached Figure Description

[0035] The preferred technical solution of the present invention will be described in detail below with reference to the accompanying drawings.

[0036] As shown in the figure, an inclined string type power collector for an automatic ground wire de-icing connection device of the present invention includes a jumper suspension clamp 1, a connecting suspension plate 2, a C-shaped support frame 3, a contact finger current-passing assembly 4, a figure-eight plate 5, and a drain clamp 7. The jumper suspension clamp 1 is connected to the jumper string. The connecting suspension plate 2 is installed around the jumper suspension clamp 1, with the jumper string connected at the upper end and the C-shaped support frame 3 connected at the lower end. A vertical connecting plate is set on the side of the central position of the main body of the C-shaped support frame 3. The contact finger current-passing assembly 4 is installed on the vertical connecting plate. A set of figure-eight plates 5 are symmetrically arranged on both sides of the C-shaped support frame 3. The figure-eight plates 5 are respectively connected to the inclined string. The current-passing connecting plate of the contact finger current-passing assembly 4 is connected to the drain plate 7-1 of the drain clamp. The other end of the drain clamp 7 grips the jumper.

[0037] It also includes counterweight plates 6, which are set on both sides of the C-shaped support frame 3.

[0038] The jumper suspension clamp 1 is a double-split jumper suspension clamp.

[0039] The connecting suspension plates 2 are symmetrically arranged on the left and right sides and installed around the jumper suspension clamps. At least one support sleeve is installed in the middle of the connecting suspension plates.

[0040] The C-shaped support frame 3 has two holes in the center of its main body to connect and fix it to the suspension plate 2, and its side is designed with a vertical connecting plate to connect to the finger flow assembly 4.

[0041] The contact finger overcurrent assembly 4 includes a contact finger assembly, a guide, a protective component, and an overcurrent connecting plate. The overcurrent connecting plate is an aluminum alloy connecting plate. The guide and protective component are arranged around the contact finger assembly for guidance and protection. One side of the overcurrent connecting plate is fixedly connected to the contact finger assembly to conduct current, and the other side is connected to the current-guiding plate of the current-guiding clamp. An adjustment hole is designed in the middle of the overcurrent connecting plate. The center line of the adjustment hole makes an angle θ with the vertical direction. The angle θ is adjustable.

[0042] The vertical connecting plate on the C-type support frame 3 has connecting holes that are fixedly connected to the mounting and adjusting holes on the flow-through connecting plate.

[0043] The figure-eight plates 5 are installed on the connecting plates on both sides of the C-shaped support frame 3 in a figure-eight shape. The connecting holes of the figure-eight plates on the outside and the connecting positions of the diagonal tie rods are adjustable. As needed, the connecting holes of the figure-eight plates can be installed at the top or the bottom to increase the electrical distance of the power take-off device.

[0044] Replace the existing jumper suspension clamp in the jumper string with jumper suspension clamp 1 to complete the jumper installation. Install the connecting suspension plate 2 around the jumper suspension clamp 1, and connect the lower end to the C-shaped support frame 3. Install a set of support sleeves 2-1 in the middle of the connecting suspension plate 2 to provide support and prevent it from shrinking under stress and affecting the jumper suspension clamp 1.

[0045] On the vertical connecting plate at the center of the main body of the C-type support frame 3, a contact finger current-passing assembly is installed. When the deflection angle of the contact finger of the power take-off device is the theoretical value θ, the two holes D1 and D2 on the C-type support frame 3 are connected to the two holes d1 and d2 on the contact finger current-passing assembly 4. When the deflection angle of the contact finger of the power take-off device is larger or smaller than the theoretical value θ, the holes D1 and D3 or D1 and D4 on the C-type support frame 3 are connected to the two holes d1 and d3 on the contact finger current-passing assembly 4 to complete the adjustment of the angle deviation ±α°.

[0046] According to the electrical distance requirements, a set of figure-eight plates 5 are installed close to the outside of the C-shaped support frame 3, either upright or upside down. Several counterweights are installed on both sides of the C-shaped support frame 3 to maintain symmetry in quantity.

[0047] Finally, several drain wire clamps 7 are installed. The drain plate 7-1 is installed on both sides of the current connection plate of the finger current flow assembly 4, and several jumper wires are clamped at the other end to realize the current flow between the jumper wires and the finger current flow assembly 4.

[0048] The figure-eight plate 5 is connected to the inclined tie rod of the automatic ground wire de-icing device, so that the two inclined tie rods are straightened by force, thereby maintaining the stability of the spatial position of the automatic ground wire de-icing device when it is closed.
