Detailed description of the invention
The invention will be further described with specific embodiment below in conjunction with the accompanying drawings, so that those skilled in the art may be better understood the present invention and can be practiced, but illustrated embodiment is not as a limitation of the invention.
The high altitude localities distribution line live working method of the present invention, including:
Operating personnel has dressed on ground under tower insulating protection apparatus, and near job position；Wherein, insulating protection apparatus includes insulating protection clothes, insulating glove, insulating cord etc.；
Operating personnel keeps not less than safe distance with electrical body or grounding body, uses insulating tool to carry out livewire work；Livewire work therein includes the test to distribution line, inspection and maintenance, such as charged for replacement overhead line structures insulator, clean and change insulator, water rinses insulator, wire is repaired in crimping and disconnecting switch and spark gap, test transformator temperature rise and dielectric loss value etc. are changed in aerial earth wire, detection poor insulator, test；
After operation completes, return to ground.
The high altitude localities distribution line live working method of the present invention is particularly suited for the distribution line of 10kV.When for the distribution line of 10kV, described safe distance is 0.6 meter.
Specifically, embodiment as shown in Figure 1, described high altitude localities distribution line live working method includes: operating personnel 4 has dressed insulation clothing in ground under tower, correct position on rod-rising tower 1 to shaft tower 1, in operation process, operating personnel is D1 with the safe distance of wire 3 electrical body such as grade, and for ensureing that operating personnel 4 does not occur injury of getting an electric shock, D1 remains not less than 0.6m.Insulating tool is insulating bar etc., it is also possible to arrange insulating cord 6 between operating personnel and described shaft tower.Operating personnel 4 is when using insulating tool to operate, insulation draws the minimum effectively insulated lengths of the bearing tools such as suspension rod to remain not less than 0.6m, the minimum effectively insulated lengths of insulating bar 5 remains not less than 0.9m, and the minimum effectively insulated lengths of live line work insulating rope 6 remains not less than 0.6m.
Embodiment as shown in Figure 2, described high altitude localities distribution line live working method includes: operating personnel 4 has dressed on ground under tower insulation clothing, enters insulated working bucket 7, then adjusts insulated working bucket 7 near operation phase conductor 3.Insulating tool is insulating glove etc..In operation process, operating personnel is D2 with the safe distance of cross-arm 2 grounding body such as grade, and for ensureing that operating personnel 4 does not occur injury of getting an electric shock, D2 remains not less than 0.6m.The minimum effectively guard space of insulating protection apparatus 8 remains not less than 0.2m.
The high altitude localities distribution line live working method of the present invention ensure that in whole operation process, and operating personnel 4 uses insulating bar method and insulating glove method that Danger Electric shock risk will not occur, and makes livewire work work safely and conveniently to complete.
The determination method of above-mentioned distance range is as follows:
When high altitude localities 10kV distribution line carries out livewire work, running voltage and switching overvoltage is there is on circuit, when insulating bar 5, insulating cord 6 and the safety protective tools 8 that the air gap between operating personnel 4 and line facility or operating personnel 4 use is not enough to bear running voltage and switching overvoltage, operation gap will be occurred to puncture or insulating tool and the edge flashing of safety protective tools and cause operating personnel 4 to get an electric shock casualty accident.
10kV distribution line maximum working voltage amplitude is 11.5kV, and the issuable maximum switching overvoltage amplitude of circuit is pressed 44kV and considered.In order to ensure the safety of operating personnel 4, under the effect of system maximum working voltage and maximum switching overvoltage, insulating tool that the air gap between operating personnel 4 and line facility and operating personnel use and safety protective tools are resistant to the effect of voltage.
According to 10kV distribution line live working gap and insulating tool and the practical situation of safety protective tools, the livewire work simulation test carried out in a large number in different altitude height areas respectively, obtained 10kV distribution network live line work typical operation gap, height above sea level is corrected along face power-frequency sparkover voltage, employing relative barometric pressure modification method by live line tool along face power-frequency sparkover voltage and live-working safety safety device.
According to distribution line live working Insulation Coordination method; simultaneously according to high altitude localities 10kV distribution line practical situation; use usage to carry out distance to determine; on the premise of keeping original margin of safety; determine the minimum effectively insulated lengths of operating personnel 4 is in operation process and wire 3 etc. is between electrical body and the grounding body such as shaft tower 1, cross-arm 2 distance D1 and D2, the insulating bar 5 used in operation process and insulating cord 6 and rubber-like and the minimum effectively guard space of resinae safety protective tools 8.
According to high altitude localities 10kV distribution line live working analog reslt, in high altitude localities, when 10kV livewire work personnel safe distance with electrical body or grounding body in operation process remains not less than 0.6m, its insulation withstanding voltage is more than system maximum operating voltage (11.5kV) and system maximum switching overvoltage (44kV)；The insulation of 10kV livewire work librarian use draws the minimum effectively insulated lengths of the bearing tools such as suspension rod to be 0.6m, the minimum effectively insulated lengths of insulating bar is 0.9m, when the minimum effective insulated lengths of insulating cord is 0.6m, the withstanding voltage of insulating tool is more than system maximum operating voltage (11.5kV) and system maximum switching overvoltage (44kV)；When minimum effective guard space that 10kV livewire work personnel use the safety protective tools such as rubber-like and resinae in operation process is 0.2m, the withstanding voltage of safety device is more than system maximum operating voltage (11.5kV) and system maximum switching overvoltage (44kV).
Embodiment described above is only the preferred embodiment lifted by absolutely proving the present invention, and protection scope of the present invention is not limited to this.The equivalent that those skilled in the art are made on the basis of the present invention substitutes or conversion, all within protection scope of the present invention.Protection scope of the present invention is as the criterion with claims.
