Abstract
Description
Technical Field
[0001] This utility model relates to the field of live-line working technology, and in particular to a bypass live-line working device. Background Technology
[0002] With live-line work becoming increasingly common, insulated drain wires are now frequently used to construct small bypass systems during live-line work. This isolates the equipment to be maintained, enabling live-line maintenance. During the replacement of sectional disconnectors under load, the insulated drain wires are typically coiled and placed on a crossarm (with insulated shielding), and then installed on both sides of the line.
[0003] However, the above operating method has the following problems: 1. Without fixing measures, the coiled insulated drain wire is easy to fall off, touching other potentials and causing a short circuit and tripping of the line. 2. There is no obvious break point in the drain wire, requiring simultaneous work on both sides during installation. 3. The crossarm needs to be insulated and shielded in advance, which involves a large amount of shielding work and carries the risk of inadequate shielding. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a bypass live-line working device to improve the safety and efficiency of operation.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A bypass live-line working device includes a drain line, an isolating switch, and a suspension assembly. One end of the drain line is connected to a first end of a main line, and the other end is connected to one end of the isolating switch. The end of the isolating switch away from the drain line is connected to a second end of the main line, so that the drain line forms a bypass channel for current. One end of the suspension assembly is connected to an overhead component on the main line, and the other end is connected to the middle section of the drain line, thereby suspending the drain line.
[0006] Furthermore, the suspension assembly includes an insulating rope and an insulating hook; the insulating hook is used to connect to the overhead component; one end of the insulating rope is connected to the insulating hook, and the other end is connected to the middle section of the drain line.
[0007] Furthermore, the suspension assembly also includes an insulating rod; the middle section of the drain line is disposed along the insulating rod and connected to the insulating rod; the other end of the insulating rope is connected to the insulating rod.
[0008] Furthermore, the length of the insulating rod is adjustable.
[0009] Furthermore, the insulating rod includes an insulating telescopic rod.
[0010] Furthermore, the suspension assembly also includes a connector; one end of the connector is connected to the drain line, and the other end is connected to the insulating rod.
[0011] Furthermore, the connector includes a cable clip.
[0012] Furthermore, the insulating suspension assembly includes at least two sets of insulating ropes and insulating hooks, with each set of insulating ropes and insulating hooks spaced apart along the length of the insulating rod.
[0013] Furthermore, it also includes a fixing member; one end of the fixing member is connected to the end of the isolating switch away from the drain line; the other end of the fixing member is used to connect to the main line.
[0014] Furthermore, insulated drain clamps are provided at both ends of the drain line, and the two insulated drain clamps are respectively connected to the first end of the main drain line and to the isolating switch.
[0015] The beneficial effects of this invention are as follows: By connecting the drain wire in series with the isolating switch, and connecting the drain wire to the first end of the main line and the isolating switch to the second end of the main line, the drain wire forms a bypass path for the current, while the isolating switch can serve as the disconnect point of the bypass system, facilitating live-line single-side operation. Simultaneously, by setting a suspension assembly to hang the drain wire on the overhead components of the overhead line, the stability of the drain wire can be improved, eliminating the risk of it falling. Since the drain wire does not need to be placed on the crossarm, there is no need for additional shielding of the crossarm, reducing workload. Attached Figure Description

[0017] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.
[0018] A bypass live-line working device includes a drain line, an isolating switch, and a suspension assembly. One end of the drain line is connected to a first end of a main line, and the other end is connected to one end of the isolating switch. The end of the isolating switch away from the drain line is connected to a second end of the main line, so that the drain line forms a bypass channel for current. One end of the suspension assembly is connected to an overhead component on the main line, and the other end is connected to the middle section of the drain line, thereby suspending the drain line.
[0019] As described above, the beneficial effects of this utility model are as follows: By connecting the drain wire and the isolating switch in series, and connecting the drain wire to the first end of the main line and the isolating switch to the second end of the main line, the drain wire forms a bypass channel for the current, while the isolating switch can serve as the disconnection point of the bypass system, facilitating live-line single-side operation; simultaneously, by setting a suspension assembly to hang the drain wire on the overhead components of the overhead line, the stability of the drain wire can be improved, eliminating the risk of the drain wire falling. Since the drain wire does not need to be placed on the crossarm, there is no need for additional shielding of the crossarm, reducing workload.
[0020] Furthermore, the suspension assembly includes an insulating rope and an insulating hook; the insulating hook is used to connect to the overhead component; one end of the insulating rope is connected to the insulating hook, and the other end is connected to the middle section of the drain line.
[0021] As described above, by setting up insulating ropes and insulating hooks, the insulating hooks connect to the overhead components on the overhead line, and the insulating ropes connect the insulating hooks to the drain line, thus improving the stability of the drain line. Furthermore, the placement, installation, and retrieval of the insulating hooks and ropes are easy, thereby reducing workload.
[0022] Furthermore, the suspension assembly also includes an insulating rod; the middle section of the drain line is disposed along the insulating rod and connected to the insulating rod; the other end of the insulating rope is connected to the insulating rod.
[0023] As described above, by setting up an insulating rod and connecting the middle section of the drain line along the insulating rod to the insulating rod, that is, by straightening the middle section of the drain line into a straight line and setting it on the insulating rod, and connecting the insulating rope to the insulating rod, the drain line is subjected to more uniform force.
[0024] Furthermore, the length of the insulating rod is adjustable.
[0025] As can be seen from the above description, the use of an adjustable-length insulating rod can accommodate drain wires of different lengths.
[0026] Furthermore, the insulating rod includes an insulating telescopic rod.
[0027] As described above, by using an insulated telescopic rod, the length of the rod can be adjusted based on its telescopic action, thus adapting it to drainage lines of different lengths.
[0028] Furthermore, the suspension assembly also includes a connector; one end of the connector is connected to the drain line, and the other end is connected to the insulating rod.
[0029] As can be seen from the above description, by setting a connector to connect the drain wire to the insulating rod, the connection strength between the drain wire and the insulating rod can be improved.
[0030] Furthermore, the connector includes a cable clip.
[0031] As described above, using cable clips as connectors makes it easier to connect, install, and disassemble the drain wire and the insulating rod, reducing workload.
[0032] Furthermore, the insulating suspension assembly includes at least two sets of insulating ropes and insulating hooks, with each set of insulating ropes and insulating hooks spaced apart along the length of the insulating rod.
[0033] As described above, by setting multiple sets of insulating ropes and insulating hooks, and spacing the insulating ropes and insulating hooks along the length of the insulating rod, the force on each position of the insulating rod is uniform, thereby improving the stability of the insulating rod.
[0034] Furthermore, it also includes a fixing member; one end of the fixing member is connected to the end of the isolating switch away from the drain line; the other end of the fixing member is used to connect to the main line.
[0035] As described above, by setting a fixing component, the isolating switch can be easily installed and retrieved by hanging it on the main line.
[0036] Furthermore, insulated drain clamps are provided at both ends of the drain line, and the two insulated drain clamps are respectively connected to the first end of the main drain line and to the isolating switch.
[0037] As can be seen from the above description, by setting insulating clamps at both ends of the drain line and connecting them to the main line and isolating switch, the connection between the drain line and the main line and isolating switch becomes more convenient.
[0038] The bypass live-line working device provided by this utility model can be applied to application scenarios where insulated lead wires are used to construct small bypass systems during load operations.

The end of the isolating switch 2 away from the current-passing wire 1 is connected to the second end of the main line 101, so that the current-passing wire 1 forms a bypass channel for current, that is, the current-passing wire 1 plays a current-passing role. The isolating switch 2 plays a role in isolation and segmentation, and has a clear disconnection point. One end of the suspension assembly 3 is connected to the overhead component 102 on the main line 101, and the other end is connected to the middle section of the current-passing wire 1, so as to suspend the current-passing wire 1.

The length of the insulating rod 33 is adjustable. For example, in this embodiment, the insulating rod 33 is an insulating telescopic rod. In other optional embodiments, the insulating rod 33 can be obtained by splicing multiple interlocking sub-rods, thereby allowing the selection of different numbers and lengths of sub-rods according to the length of the drain line 1 to obtain an insulating rod 33 adapted to the length of the drain line 1.
[0042] Meanwhile, the suspension assembly 3 also includes a connector 34; one end of the connector 34 is connected to the drain line 1, and the other end is connected to the insulating rod 33. For example, in this embodiment, the connector 34 is a cable clip.
