Abstract
The invention relates to an operational method for supporting a 10kV-lead wire of an aerial lift device of an insulating arm. The operational method comprises the following steps of: shielding the lead wire, installing an insulated balance cross arm and supporting the lead wire. The operational method has the characteristics of more extensive application range and smaller topographic constraint, saves more manpower and material resources, and makes up the defect of great restrictions on conditions such as topography, vehicles and the like in the prior art. The operational method has a very great practical value in enlarging live-wire work fields and improving power supply reliability in distribution network growing today.
Description
Technical field
The present invention relates to the distribution line live working method in the electric power system, relate in particular to a kind of operational method for supporting 10 kV-lead wire of aerial lift device with insulating arm.
Background technology
Along with developing rapidly of power distribution network, social need for electricity constantly increases, can't newly added equipment on the circuit near the user applies electricity consumption place.If will increase electric pole, necessity is taked power cut construction, and the whole process time spent is longer, will lose big volume and electricity, influences power supply reliability.Also need carry out multiple labour operation after construction finishes, increase the scheduling operation step.If there is not branch line of expenditure on the equipment straight line pole from afar, perhaps put a cable house service, will improve construction cost greatly.
Summary of the invention
In order to overcome the deficiency that above-mentioned prior art exists, the present invention aims to provide a kind of operational method for supporting 10 kV-lead wire of aerial lift device with insulating arm, to solve in the 10kV distribution line, when needing newly added equipment, near no available electric pole, be subjected to landform to limit two aerial lift device with insulated arm can't to be used the problem of the vertical rod that can only have a power failure.
Operational method for supporting 10 kV-lead wire of aerial lift device with insulating arm of the present invention may further comprise the steps:
A. cover lead: be installed in insulating sleeve on the three-phase conducting wire according to the order of sequence;
B., the insulation balance cross arm is installed: a strut is installed on the insulation bucket of aerial lift device with insulated arm, and an insulation balance cross arm that is provided with three standoffs is installed on the described strut, and also be provided with safeties on the described standoff;
C. support wire: three-phase conducting wire is placed respectively in three standoffs on the balance cross arm of insulation described in the step B, and close the safeties of the above standoff, described strut is risen to support described lead;
In above-mentioned operational method for supporting 10 kV-lead wire of aerial lift device with insulating arm, in the described steps A order of insulating sleeve by phase in from inside to outside or first two rear flank is installed on the three-phase conducting wire.
In above-mentioned operational method for supporting 10 kV-lead wire of aerial lift device with insulating arm, among the described step C standoff in twos spacing be 1m.
In above-mentioned operational method for supporting 10 kV-lead wire of aerial lift device with insulating arm, be provided with roller bearing in the standoff among the described step C.
Owing to adopted above-mentioned technical solution, operational method step of the present invention is clear, and easy operating, aerial lift device with insulated arm are finished support wire, live line working simultaneously.Insulation quarantine measures in the operation process put in place, the coefficient of safety height.Solved in the engineerings such as capital construction, industry expansions because the landform restriction problem of necessary power failure vertical rod has in the past improved power supply reliability greatly.Compared with prior art, range of application of the present invention is more extensive, is subjected to landform restriction littler, more uses manpower and material resources sparingly, and is subjected to the big defectives of condition restriction such as landform, vehicle in having remedied compared to existing technology.This operational method to enlarging the live line working field, improves power supply reliability in power distribution network growing today, has great practical value.

Fig. 2 is the operation chart of a kind of operational method for supporting 10 kV-lead wire of aerial lift device with insulating arm of the present invention.
Embodiment
See also Fig. 1, Fig. 2, a kind of operational method for supporting 10 kV-lead wire of aerial lift device with insulating arm of the present invention may further comprise the steps:
Earlier insulating sleeve is installed on the three-phase conducting wire 10 according to the order of sequence; Again a strut 1 is installed on the insulation bucket 11 of aerial lift device with insulated arm, and an insulation balance cross arm 2 that is provided with three standoffs 20 is installed on the strut 1, and also be provided with safeties 21 on the standoff 20; At last three-phase conducting wire 10 is placed respectively in three standoffs 20 on the insulation balance cross arm 2, and shut the safeties 21 of standoff 20, by hoist engine 3 strut 1 is risen to support lead 10, when strut 1 rises, need to keep insulation balance cross arm 2 to be in poised state, till lead 10 rising heights satisfy safe distance.
In above-mentioned operational method for supporting 10 kV-lead wire of aerial lift device with insulating arm, the order of insulating sleeve by phase in from inside to outside or first two rear flank can be installed on the three-phase conducting wire; In addition, three standoffs 20 of insulation on the balance cross arm 2 in twos spacing be 1m; In the standoff 20 roller bearing is arranged, make lead 10 avoid lead to bear extra pulling force, also have safeties 21 on the fixture, prevent lead 10 slippages in the support process being free to slide along line direction.Come support wire 10 by hoist engine 3, both guaranteed that insulation is isolated between line, can prevent lead 10 move left and right again.
In the above-mentioned operational method for supporting 10 kV-lead wire of aerial lift device with insulating arm, in support wire 10 processes, should check whether the lead binding on the electric pole of both sides is firm, if any loosening, off-line phenomenon, colligation can be carried out operation after reinforcing again; During lead 10 liftings, slowly carry out, rock to prevent lead, in order to avoid cause phase fault.
Above embodiment has been described in detail the present invention, and those skilled in the art can make the many variations example to the present invention according to the above description.Thereby some details among the embodiment should not constitute limitation of the invention, and the scope that the present invention will define with appended claims is as protection scope of the present invention.
