Description
Technical field
The present invention relates to a kind of scalable insulating bar device, particularly a kind of ground electrical verification of the complete earth connection that uses for the city overhead transmission line and the scalable insulating bar device of ground dislodging earth connection.
Background technology
At present, a lot of cities and county town distribution overhead transmission line be a large amount of to use outdoor public change platform, the horizontal bus that becomes the fuse switch of platform and high voltage support frame apart from ground 4.5m about; According to city and county town development plan, every overhead transmission line of striding the road all requires to change cable into and passes by on one's way, and according to " architectural electricity installation atlas ", the outside cable head bracket requires to be designed to apart from about the 4.5m of ground; Along with the high speed development of city and county town real estate, the new user who connects from original overhead transmission line T also adopt cable line as own box-type substation or high voltage power distribution power circuit, and the support of cable line top cable end apart from ground 4.5m about.
Ground wire hitching is used for preventing that circuit from switching on suddenly on the distribution line that has a power failure or in the public change platform, avoid jeopardizing Construction and Maintenance personnel's life just on the line.Therefore, before the line construction maintenance, the necessary true no-voltage in priori open-wire line road of circuit and hanging earthing conductor also will be extractd earth connection after line maintenance finishes.
Past, the electrical verification of 10kV overhead transmission line and hanging earthing conductor all carry out at electric pole, before the electrical verification, step on the bar personnel and will carry out following work: prepare climbers, check whether climbers are intact, fasten seat belts, carry the big rope that transmits electroscope and earth connection, upper boom, determine erect-position, (ground staff fastens back on big rope with electroscope) stepped on the bar personnel and taken over the electroscope electrical verification by big rope, with big rope electroscope is passed to personnel under the bar after identifying no-voltage, (ground staff fastens back on big rope with the earth connection rod) stepped on the bar personnel and obtained the earth connection rod by big rope, finishes the task of hanging earthing conductor at last.
Equally, the 10kV overhead transmission line was plucked earth connection and was also all carried out at electric pole in the past, before plucking earth connection, step on the bar personnel and will carry out following work: prepare climbers, check whether climbers are intact, fasten seat belts, carry the big rope, the upper boom that transmit earth connection, determine erect-position, open big rope, take three earth rods respectively, fastened three earth rods, by big rope earth connection passed to the ground staff with an end of big rope.
High speed development along with urbanization, the T of overhead transmission line meets the user also to be increased thereupon, the road hardening face is increasing, and underground utilities distribute more and more intensive, and the earth terminal ground connection drill rod of installing earth connection brought very big inconvenience when these factors were overhauled city 10kV overhead transmission line:
One, along with T connects increasing of user, the earth point of earth connection namely will increase, and the time that earth connection is installed accounts for the ratio of scheduled outage time to be increased thereupon;
Two, along with the sclerosis on road surface, brought difficulty to earth connection is installed, drill rod is difficult to hammer into underground, and earth resistance does not meet safety value yet simultaneously;
Three, along with the increasing of underground utilities, when hammering into drill rod, very easily cause the accident or fault.The subsurface of highway and both sides, pavement may be equipped with following facility at present:
1, property right belongs to the power cable of power supply department;
2, other cables, for example: the cable of field cable, railway cable, telecommunication cable, road lighting cable, each grass-roots unit etc.;
3, plastic tube (as running water pipe, blowdown pipe), clay pipe;
4, iron pipe, for example: water pipe, steam heating pipe, natural gas tube.
These cables and pipeline do not have whole marks to come out on the ground, and the degree of depth is not clear.As long as break ground or moving road, just may suffer from them.By to the analysis of in the past cable grounding fault and short trouble and operation is taked to overhead transmission line safety measure and the space environment analysis of shaft tower, below problem need to be resolved hurrily:
1, how under the environment of sclerosis, earthing device is installed easily;
2, how when being installed, not damage by earthing device underground utilities.
3, shorten the time of installing earth connection as far as possible, improve power supply reliability;
4, the earthing device of An Zhuaning meets safety requirements.
