Abstract
The utility model discloses a device for handling failure of an overhead line without power cut. The device comprises supporting poles and a temporary cable. A bearing steel rope is erected between the two supporting poles; a tackle is arranged on the bearing steel rope; the temporary cable is arranged on the tackle; two ends of the temporary cable are respectively connected overhead lines at two ends of a work area; overhead lines in the work area are powered off; and the temporary cable consisting of three single-phase flexible cables is respectively connected user circuits in the work area by the aid of branch lines. The device bridges the overhead lines in the work area by the aid of the temporary cable, powers off the overhead lines in the work area so that staff can examine, repair and maintain the power-off overhead lines while the temporary cable supplies power for users in the work area, ensures no power cut or less power cut for the users, and reduces economic loss.
Description
One, technical field: the utility model relates to a kind of power failure processing unit, particularly relates to the do not have a power failure device of handling failure of a kind of overhead transmission line.
Two. background technology: along with the raising of development and national economy and living standards of the people, society is more and more higher to the reliability requirement of power supply, because the restriction of various conditions, most of user can not reach dual power supply, thereby shows out the necessity of the comprehensive uninterrupted operation of distribution line especially.
The 10KV distribution line is a part and parcel in the distribution network, is directly in the face of user's infrastructure, because distribution line network complexity, area coverage are big, makes it be covered with each corner in supply power in the business office's scope.But, the distribution network insulation level is low, break down easily under atmospheric over-voltage, equipment natural aging or other extraneous factor effects, maintenance workload is big, no matter is social benefit or economic benefit, and the 10KV power distribution network is forced to stop transport and all can produces the loss that can't estimate.
Three. the content of utility model:
Technical problem to be solved in the utility model is: overcome the deficiencies in the prior art, a kind of device of reasonable in design, simple in structure, efficient is high and the overhead transmission line that reduces loss of outage does not have a power failure handling failure is provided.
The technical solution of the utility model is: the do not have a power failure device of handling failure of a kind of overhead transmission line, contain support bar and temporary cable, set up messenger cable between the described support bar, this messenger cable is provided with coaster, temporary cable is arranged on the described coaster, the two ends of described temporary cable are connected with the overhead wire at two ends, working region respectively and make the power failure of opening circuit of overhead wire in the working region, and described temporary cable is connected with subscriber line circuit in the working region respectively by branch line.
Described temporary cable is made up of three single-phase flexible cables.
The beneficial effects of the utility model are:
1, the utility model utilizes temporary cable with the overhead wire cross-over connection in the working region, make overhead wire power failure in the working region, the staff overhauls the overhead wire that has a power failure and safeguards, and temporary cable provides power supply for the user in the working region, guarantee that the user does not have a power failure or few the power failure, reduce economic loss.
2, the utility model sets up messenger cable between support bar, and coaster is set on the messenger cable, is convenient to quick, the light temporary cable that sets up, high efficiency, and interruption duration is short, loss of outage is little.
3, the utility model is reasonable in design, simple in structure, efficient is high and reduce loss of outage, has good economic benefit and social benefit after the popularization.
Four. description of drawings:
Fig. 1 is a structural representation of the present utility model.
Five. embodiment:
Embodiment: referring to Fig. 1, among the figure, 1-circuit breaker, 2-overhead wire, 3-line bar, 4-user, 5-support bar, 6-temporary cable, 7-messenger cable, 8-coaster.
The do not have a power failure device of handling failure of overhead transmission line contains support bar 5 and temporary cable 6, set up messenger cable 7 between the support bar 5, this messenger cable 7 is provided with coaster 8, temporary cable 6 is arranged on the coaster 8, be convenient to move, the two ends of temporary cable 6 are connected with the overhead wire 2 at two ends, working region respectively and make the power failure of opening circuit of overhead wire 1 in the working region, and temporary cable 6 is connected with user 4 circuit in the working region respectively by branch line.
Temporary cable 6 is made up of three single-phase flexible cables.Certainly, as required and field condition, also can not set up support bar 5, but utilize original line bar 3 (perhaps other parallel line bars) to set up messenger cable 7, to reduce engineering time and expense.
During use,, temporary cable 6 is moved along messenger cable 7, realize setting up fast, shorten interruption duration by hoist engine with connecting rope and drafting tool.Overhead wire 2 maintenances finish, and remove temporary cable 6, support bar 5 and messenger cable 7, remove circuit breaker 1 again, connect overhead wire 2, carry out normal power supply.
Claims (2)
1. the overhead transmission line device of handling failure that do not have a power failure, contain support bar and temporary cable, it is characterized in that: set up messenger cable between the described support bar, this messenger cable is provided with coaster, temporary cable is arranged on the described coaster, the two ends of described temporary cable are connected with the overhead wire at two ends, working region respectively and make the power failure of opening circuit of overhead wire in the working region, and described temporary cable is connected with subscriber line circuit in the working region respectively by branch line.
2. the do not have a power failure device of handling failure of overhead transmission line according to claim 1, it is characterized in that: described temporary cable is made up of three single-phase flexible cables.
