Description
Technical field：
The present invention relates to the method and its Special combined tools of a kind of ground potential method charged for replacement arrester, it is widely used in making somebody a mere figurehead
Distribution line ground potential method is changed 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, the breakdown voltage ratio in gap on the line or in equipment
The lightning impulse dielectric level of circuit or equipment is low, and gap is in and is dielectrically separated from state under normal operating voltage, in overvoltage
Protection circuit or apparatus insulated effect are played in the lower breakdown ground connection in gap, electric discharge, step-down.Metal zinc oxide lightning arrester is because of its property
Excellent can be widely used in 10kV distribution lines, to over-voltage, protect distribution line or equipment.
In actual applications, because operation year limit for length, running environment are severe, particularly on the ground that lightening activity is more active
Area, situations such as often there is aging, failure in some arresters, have a strong impact on the safe operation of distribution line and equipment, it is necessary to
These arresters are changed.
The replacing 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 typically when nonessential.
Current charged for replacement arrester work 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
Change arrester and there is deficiency everywhere：One is limited by orographic condition, if electric pole is in the complexity landform such as mountain region, orchard, insulation
Bucket arm vehicle cannot reach job position, it is impossible to carry out operation；Two are 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；Three is that operating personnel has security risk, and distribution line is compact, and electrical equipment arrangement is intensive,
Job area is narrow, and operating personnel is susceptible to mutually and terra short or phase fault is dangerous near electrical body operation；Four is work effect
Rate is low, and job step is more, and program is complicated, and time-consuming for work.
Earth potential working method is that operating personnel climbs shaft tower to appropriate location by climbers, and band is carried out by insulating bar
Electric upkeep operation, adopting said method is changed when arrester can overcome the shortcomings of that intermediate potential method changes arrester to be present, but
The specific purpose tool of arrester is changed without ground potential method at present, causing ground potential method to change arrester work cannot carry out.
The content of the invention：
A kind of simple structure is provided it is an object of the invention to overcome the shortcomings of above-mentioned prior art, easy for installation, safety can
Lean on, it is applied widely, improve livewire work efficiency, reduce enterprises using the labor cost ground potential method change arrester method and its
Special combined tools.
The purpose of the present invention can be reached by following measure：A kind of dedicated set of ground potential method charged for replacement arrester
