Abstract
Power circuit sag adjustment device, it is made of some spools, bracing wire and some reels, spool is fixed on below cross-arm, power circuit one end is connected with spool, reel is fixed on electric pole lower part, it is connected between spool and reel by bracing wire, spool, bracing wire and reel, which are all adopted, to be made from an insulative material.The present invention is by the way that power circuit is connected with spool, the folding and unfolding of power circuit is realized by bracing wire drive spool by reel, so as to fulfill the adjustment to arc sag circuit, adjustment process has the advantages that simple in structure, easy to adjust and safe and efficient without power-off.
Description
Technical field
The present invention relates to power circuit security maintenance technical field, and in particular to a kind of power circuit sag adjustment device.
Background technology
The power circuit set up between electric pole when in use between in arc sag phenomenon occurs, if arc sag is apart from mistake
Greatly, will constitute a threat to the personal safety of neighbouring personnel, it is all that circuit is powered off first to solve power circuit arc sag at present, so
Step on bar by electric power maintenance personnel afterwards to be adjusted arc sag circuit, whole process is time-consuming and laborious, can also influence making for power consumer
With.
The content of the invention
The present invention provides a kind of power circuit sag adjustment device, to solve power circuit arc sag existing in the prior art
The problem of damaging to periphery personnel.
The technical solution adopted by the present invention to solve the technical problems is：
A kind of power circuit sag adjustment device, is made of, spool is fixed on horizontal stroke some spools, bracing wire and some reels
Load lower section, power circuit one end are connected with spool, and reel is fixed on electric pole lower part, passes through between spool and reel
Bracing wire is connected, and spool, bracing wire and reel, which are all adopted, to be made from an insulative material.
The present invention operation principle be：When arc sag phenomenon occurs in power circuit, electric power maintenance personnel can be by rotating spiral
Wheel, reel drive the spool below cross-arm to rotate by bracing wire, and spool is so as to drive power circuit to turn along spool
Dynamic tightening.
The present invention drives spool to realize electric power by the way that power circuit is connected with spool, by reel by bracing wire
The folding and unfolding of circuit, so as to fulfill the adjustment to arc sag circuit, adjustment process without power-off, have it is simple in structure, easy to adjust and
The advantages of safe and efficient.
Brief description of the drawings
The present invention is further described with reference to the accompanying drawings and examples.
Fig. 1 is the scheme of installation of apparatus of the present invention.
1 electric pole, 2 cross-arms, 3 power circuits, 4 spools, 5 bracing wires, 6 reels in figure.
Embodiment
As shown in the figure, a kind of power circuit sag adjustment device, by 6 groups of some spools 4, bracing wire 5 and some reels
Into spool 4 is fixed on the lower section of cross-arm 2, and 3 one end of power circuit is connected with spool 4, and reel 6 is fixed under electric pole 1
Portion, is connected, spool 4, bracing wire 5 and reel 6 all use insulating materials system between spool 4 and reel 6 by bracing wire 5
Into.
The present invention operation principle be：When arc sag phenomenon occurs in power circuit, electric power maintenance personnel can be by rotating spiral
Wheel, reel drive the spool below cross-arm to rotate by bracing wire, and spool is so as to drive power circuit to turn along spool
Dynamic tightening.
The present invention drives spool to realize electric power by the way that power circuit is connected with spool, by reel by bracing wire
The folding and unfolding of circuit, so as to fulfill the adjustment to arc sag circuit, adjustment process without power-off, have it is simple in structure, easy to adjust and
The advantages of safe and efficient.
