Description
Technical field：
The present invention relates to a kind of methods and its Special combined tools of ground potential method charged for replacement arrester, are widely used in
Overhead distribution ground potential method is replaced in the work of arrester, belongs to distribution line hotline maintenance site technology field.
Background technology：
Arrester is exactly the artificial manufacture insulation weak spot i.e. device in gap on the line or in equipment, the breakdown potential in gap
Pressure ratio circuit or the lightning impulse dielectric level of equipment are low, and gap is in and is dielectrically separated from state under normal operating voltage, in mistake
Protection circuit or apparatus insulated effect are played in the breakdown ground connection in gap under voltage, electric discharge, decompression.Metal zinc oxide lightning arrester because
Its function admirable is widely used in 10kV distribution lines, to over-voltage, protects distribution line or equipment.
In practical applications, since operation year limit for length, running environment are severe, particularly on the more active ground of lightening activity
Situations such as area, aging, failure often occur for some arresters, seriously affect the safe operation of distribution line and equipment, it is necessary to
These arresters are replaced.
The replacement arrester that has a power failure needs to interrupt some region of supply of electric power, influences the normal production and life of a large number of users
It is living, power supply reliability is reduced, this operating type has increasingly been not suitable with the requirement of electric company's good service and current electricity
The development trend of net, does not use generally when nonessential.
Charged for replacement arrester work at present is carried out by medial potential working method, i.e., operating personnel wears insulation safety
Cap, wears a full set of insulation clothing, and operation aerial lift device with insulated arm insulation bucket carries out upkeep operation close to job position.Medial potential working method is more
It is insufficient everywhere to change arrester presence：When limited by orographic condition, if electric pole is in mountainous region, orchard when complicated landforms, insulation
Bucket arm vehicle can not reach job position, can not carry out operation；Second is that entreprise cost is high, it is necessary to set out operating personnel's quantity more, go out
Dynamic oversize vehicle aerial lift device with insulated arm；Third, operating personnel, there are security risk, distribution line is compact, electrical equipment arrangement is intensive,
Job area is narrow, and operating personnel easily occurs mutually and terra short or phase fault is dangerous close to electrical body operation；Fourth, work is imitated
Rate is low, and job step is more, and program is complicated, and time-consuming for work.
Earth potential working method, that is, operating personnel climbs shaft tower to appropriate location by climbers, and band is carried out by insulating bar
Electric upkeep operation, adopting said method replace existing deficiency when arrester can overcome intermediate potential method replacement arrester, still
The specific purpose tool of arrester is replaced without ground potential method at present, ground potential method is caused, which to replace arrester work, to carry out.
The content of the invention：
A kind of simple in structure, easy for installation, peace is provided it is an object of the invention to overcome the shortcomings of above-mentioned prior art
Complete reliable, applied widely, raising livewire work efficiency reduces the method that the ground potential method of enterprises using the labor cost replaces arrester
And its Special combined tools.
