Description
Technical field
The present invention relates to the combination tool that a kind of earth potential live eliminates transmission line of electricity drainage plate heating defect, extensive use
In the work that transmission line of electricity ground potential method eliminates drainage plate heating defect, belong to electric transmission line hot-line Overhaul site technology neck
Domain.
Background technology
Artery of the overhead transmission line as electric system, is the basis of electric power netting safe running.However, due to transmission line of electricity
It is throughout the year exposed to run in the wild, often can be by infringements such as meteorological disaster, the destruction of artificial external force and circuit self deteriorations, to defeated
The safe operation of electric line brings threat.Thunder-strike phenomenon and flashover such as thundery sky, the harm of the icing in winter, day are aerial
Bird pest, insulator caused by stress rupture caused by also having the pulling force of circuit itself and loose contact are burnt out with circuit fever.Its
In, the fever of transmission line of electricity drainage plate is a kind of relatively conventional failure, particularly during the broiling summer, because line load is big,
Environment temperature is high, the dirty aging of wire clamp, the problem of may causing wire clamp to generate heat, if finding not in time or defect expressivity is too late
When, high risks, serious threat safe operation of power system can be caused to transmission line of electricity.
The elimination of common transmission line of electricity drainage plate heating defect mainly has power failure processing and two kinds of solution party of on-line treatment
Case.Processing have a power failure, it is necessary to line load is poured into an other circuit, not only heavy workload, coverage is wide, and easily draws
Play another circuit overload or circuit fever.Therefore, on-line treatment becomes the head for eliminating transmission line of electricity drainage plate heating defect
The choosing wanted.
Hot line maintenance mode includes earth potential working method and equipotential live line work method, and earth potential working method is usually used in
Electric transmission line isolator zero-detection etc. simply works；Equipotential live line work method is usually used in the complex job project such as replacing insulator under electrified.
Traditional powered elimination drainage plate heating defect generally carries out equipotential defect elimination with flat ladder method or rope ladder method.
But the form of transmission tower and the distribution of conducting wire have extreme influence to carrying out Equipotential live working, work as corner
When shaft tower angle is more than 30 degree, one phase of interior angle side can not be by flat ladder method operation, and when conducting wire is using disposal arrangement, upper phase is with
The equipotential method operation of tradition can not mutually be passed through.Meanwhile can the order of severity of drainage plate fever also directly affect and carry out
Equipotential live working, can not also be carried out when heating temp is more than 65 degree by equipotential mode.Through statistics, upper half in 2017
Wire clamp heating problem occurs altogether for Nian Mou cities 27 times, and Equipotential live working solves 21 times, because of pole tower forms, the mutually inferior reason of fever
Can not livewire work 4 times, because wire clamp heating temp is excessive, personnel can not be 3 times by equipotential live line work method defect elimination.Meanwhile wait electricity
There is the problems such as higher to operating personnel's level of skill, physical fitness requirement, the activity duration is long, danger coefficient is high in the powered defect elimination in position.
At present, it would be highly desirable to a kind of powered transmission line of electricity drainage plate that eliminates of ground potential method that can solve above-mentioned technical problem occur and send out
The combination tool of thermal defect.
