Abstract
The utility model discloses a branching line support frame for the replacement of an isolating switch in a 10 kV distribution line, which comprises a fixed chuck and a movable chuck. A movable pull rod passes through the fixed chuck and the movable chuck. Relative to the fixed chuck, the outer end of the movable chuck is connected with a bushing sleeved outside the movable pull rod. The other end of the bushing is connected with a four-way piece, wherein the interfaces of the four-way piece are mutually perpendicular. A sleeve coaxial with the pull rod is arranged in the four-way piece, and the inner diameter of the sleeve is larger than the diameter of the pull rod. A radial fixed plate is arranged in the sleeve. The inner cavity of the outer end of the movable pull rod, which extends out of the four-way piece, is internally provided with a compression spring connected with the fixed plate. The branching line support frame is fixed to a cross arm through the fixed chuck and the movable chuck. Meanwhile, a branching line is fixed through a snap ring at the tail end of the branching line support frame, and a lightning shield line is fixed through a fixed ring at the tail end of a lightning shield line support rod. Therefore, the branching line and the lightning shield line are effectively prevented from swing. The risk of short circuit due to the reason that the branching line and the lightning shield line are contacted with an electrified body during swing in the prior art is avoided.
Description
Technical field
The utility model relates to a kind of distribution line, particularly a kind of shunt line bracing frame for 10 KV distribution track replacement isolating switches.
Background technology
Isolating switch often occurring on 10 KV distribution circuits burns, need live line working to change, when changing the disconnecting link cross-arm in the past, need to use cross arm shielding cover and polylith insulated target that cross-arm and disconnecting link are partly covered, and shunt line can't be effectively fixing, and cover and demolishing process consuming time more and potential safety hazard is large, the personnel that easily cause touch cross-arm and electrified body.10 KV distribution circuit on-loads are changed isolating switch, conventionally must use the multiple insulation such as insulated target, cross arm shielding cover to cover apparatus, and are not only consuming time but also have a great potential safety hazard.Shunt line can't be effectively fixing in addition, and the lightning conducter of lower end is removed the rear unsettled greatly potential safety hazard that also exists.
The utility model content
The purpose of this utility model is to provide a kind of handling safety, efficient shunt line bracing frame.
This bracing frame for 10 KV distribution track replacement isolating switches that the utility model provides, comprise fixed chuck and movable chuck, there is active pull rod to pass fixed chuck and movable chuck, the outer end of the relative fixed chuck of movable chuck is connected with and is placed in the outer sleeve pipe of active pull rod, the other end of sleeve pipe is connected with the orthogonal four-way of interface, have in the four-way and pull bar coaxial line, the internal diameter sleeve greater than the pull bar diameter, fixed head is radially arranged in the sleeve, and active pull rod stretches out in the outer end inner chamber of four-way has Compress Spring to be connected with fixed head.
The width of described fixed head is less than the internal diameter of pull bar.
There is the notch greater than the fixed head width at corresponding fixed head place on the described pull bar.
Another docking port of described four-way is connected with respectively lightning-arrest lead-in wire support bar and shunt line support bar; The end of lightning-arrest lead-in wire support bar has retainer ring, and the end of shunt line support bar has snap ring.
The utility model is fixed by fixed chuck and movable chuck and cross-arm, snap ring by shunt line support bar end is the fixing lightning-arrest lead-in wire of retainer ring of shunt line, lightning-arrest lead-in wire support bar end fixedly, effectively prevented simultaneously the swing of shunt line and lightning-arrest lead-in wire, overcome and touched the danger that electrified body causes short circuit when prior art shunt line and lightning-arrest lead-in wire swing, when efficiently solving in the national grid power safety fixture wire such as charged breaking and connecting nonloaded line, coupling capacitor, lightning arrester, trap, the difficult problem of the regulation that should take to prevent that shunt line from swinging.

Embodiment
As shown in Figure 1 and Figure 2, this shunt line bracing frame for 10 KV distribution track replacement isolating switches that the utility model provides comprises fixed chuck 1, movable chuck 2, active pull rod 3, sleeve pipe 4, four-way 5, Compress Spring 8, lightning-arrest lead-in wire support bar 9, shunt line support bar 10.Active pull rod 3 passes fixed chuck 1 and movable chuck 2, sleeve pipe 4 be positioned at movable chuck 2 relative fixed chucks 1 the outer end, be enclosed within outside the active pull rod 3.The orthogonal four-way 5 of the other end connecting interface of sleeve pipe 4, another docking port of four-way 5 connect respectively lightning-arrest lead-in wire support bar 9 and shunt line support bar 10.Have in the four-way 5 and active pull rod 3 coaxial lines, the internal diameter sleeve 6 greater than active pull rod 3 external diameters, fixed head 7 is radially arranged in the sleeve 6.Active pull rod 3 stretches out in the outer end inner chamber of four-way 5 Compress Spring 8, and its end is connected with the shrouding of active pull rod 3 outer ends, the other end is connected with fixed head 7.The width of fixed head 7 is less than the internal diameter of active pull rod 3, and there is the notch greater than fixed head 7 width at corresponding fixed head 7 places on the pull bar 3.The end of lightning-arrest lead-in wire support bar 9 has retainer ring 11, and the end of shunt line support bar 10 has snap ring 12.
Operating process of the present utility model is as follows: the one side of fixed chuck 1 being blocked the cross-arm angle steel, pull out four-way 5, four-way 5 drives movable chuck 2 outward movment by sleeve pipe 4, until the distance between movable chuck 2 and the fixed chuck 1 stops drag four-way 5 greater than the another side width of cross-arm.In pulling four-way 5, Compress Spring 8 in the active pull rod 3 is compressed, when stopping drag four-way 5, Compress Spring 8 is replied, promote sleeve pipe 4 returns by the fixed head 7 that is connected with Compress Spring 8, thereby make movable chuck 2 hold out against the another side of cross-arm, make fixed chuck 1 and movable chuck 2 and cross-arm firmly fixing.Then shunt line is fixed in the corresponding snap ring 12, lightning-arrest lead-in wire is fixed to the safety that can begin isolating switch in the retainer ring 11 and more changes jobs.
