Description
Technical field
The present invention relates to a kind of telescopic insulation rod device, particularly to the telescopic insulation rod device of the ground electrical verification of a kind of complete earth lead used for city overhead transmission line and ground dislodging earth lead.
Background technology
At present, a lot of cities and county town distribution overhead line use outdoor public change platform in a large number, become the fuse switch of platform and horizontal bus distance ground about the 4.5m of high voltage support frame；According to city and county town development plan, every overhead transmission line across road is desirable that and changes electric cable passway hole into, and according to " architectural electricity installation atlas ", outside cable head bracket requires to be designed as distance ground about 4.5m；Along with the high speed development in city and county town real estate, from original overhead transmission line T new user connect be also adopted by cable run as oneself box-type substation or high voltage power distribution power circuit, and the support of cable run top end distance ground about 4.5m.
Ground wire hitching, on the distribution line having a power failure or in public change platform, is used for preventing circuit to be energized suddenly, it is to avoid jeopardize the life of the personnel of Construction and Maintenance just on the line.Therefore, before line construction maintenance, circuit must the true no-voltage in priori open-wire line road and hanging earthing conductor, also to extract earth lead after line maintenance.
Past, 10kV overhead transmission line electrical verification and hanging earthing conductor all carry out on electric pole, before electrical verification, step on bar personnel and to carry out following work: prepare foot button, check that whether climbers are intact, fasten seat belts, carry the big rope of transmission electroscope and earth lead, upper boom, determine erect-position, (electroscope is fastened after on big rope by ground staff) is stepped on bar personnel and is taken over electroscope electrical verification by big rope, with restricting greatly, electroscope is passed to personnel under bar after identifying no-voltage, (ground connection bar is fastened after on big rope by ground staff) is stepped on bar personnel and is obtained ground connection bar by big rope, finally complete the task of hanging earthing conductor.
Equally, conventional 10kV overhead transmission line is plucked earth lead and is also all carried out on electric pole, before plucking earth lead, step on bar personnel and to carry out following work: prepare climbers, check that whether climbers are intact, fasten seat belts, carry the transmission big rope of earth lead, upper boom, determine erect-position, open big rope, take three earth rods respectively, fastened three earth rods with one end of big rope, by big rope, earth lead passed to ground staff.
High speed development along with urbanization, the T of overhead transmission line meets user also to be increased therewith, road hardening face is increasing, and underground utilities distribution is more and more intensive, and earth terminal and the ground connection drill rod of installing earth lead when city 10kV overhead transmission line is overhauled by these factors bring very big inconvenience:
One, along with T connects increasing of user, namely the earth point of earth lead to increase, and the time of installation earth lead accounts for the ratio of scheduled outage time to be increased therewith；
Two, along with the hardening on road surface, bringing difficulty to installing earth lead, drill rod is difficult to hammer into underground, and earth resistance does not meet safety value yet simultaneously；
Three, increasing along with underground utilities, when hammering into drill rod, very easily causes the accident or fault.The subsurface of current highway and footpath both sides is likely to be equipped with following facility:
1, property right belongs to the power cable of power supply department；
2, other cables, for instance: field cable, railway cable, communication cable, road lighting cable, each grass-roots unit cable etc.；
3, plastic tube (such as running water pipe, blow-off pipe), clay pipe；
4, iron pipe, for instance: water pipe, steam heating pipe, natural gas tube.
These cables and pipeline are not all marked on the ground, and the degree of depth is failed to understand.As long as breaking ground or dynamic road, it is possible to suffer from them.By to the analysis of conventional cable earth fault and short trouble and the spatial environments analysis to the overhead transmission line safety measure taked of operation and shaft tower, below problems demand solve:
1, how under the environment of hardening, grounding device is installed easily；
2, how underground utilities are not damaged when installing grounding device.
3, shorten the time of installing earth lead as far as possible, improve power supply reliability；
4, the grounding device installed meets safety requirements.
