Abstract
The invention relates to a ground wire energy-extracting power supplying technology of a high-tension overhead line. A current/voltage transformer is connected to an overhead line, a rectification facility and a voltage stabilizing facility are connected to the current/voltage transformer, an energy storage facility is arranged between the rectification facility and the voltage stabilizing facility, and a lightning protection device is connected to the current/voltage transformer. Under the condition of no power failure of the high-tension overhead line, a current transformer or voltage transformer energy-extracting and electricity-taking scheme is decided to be adopted according to a power supply load requirement and a specific electricity-collecting environment after being designed, and implemented after being approved by a management department. According to the ground wire energy-extracting power supplying technology, lost electric energy is collected by an electricity-collecting device, and is applied to power supply of monitoring equipment; compared with a solar power supplying and lead high-tension induction electricity-collecting technology, the ground wire energy-extracting power supplying technology has the advantages of being remarkable in advancement and applicability, and achieving the technical purpose of reliable power supply of equipment on a tower.

Technical field
The present invention relates to a kind of high-tension overhead line ground wire and take out energy power supply technique, belong to intelligent grid technical field.
Background technology
Electric power is to carry out the requisite basic motive power of modernization construction, to national economy and people's lives important in inhibiting.Because electric power has production, supply, sells and complete simultaneously, thereby the citation form that electrical production is managed, i.e. generating-transmission of electricity-distribution-electricity consumption are determined.In this process, the fault of arbitrary link and error all will exert an influence to entirety.So, must focus on the management of generating, transmission of electricity, power transformation, electricity consumption links.For power transmission and equipment thereof---high voltage overhead power circuit (comprising transmission of electricity, distribution line), as one of most important electric equipment in electric power system, has important function.
High-tension line, for electric energy transmitting, has many advantages, and it is easy to use, clean, is easy to transmission, concentrates and controls, and is easy to be converted into other forms of energy, is the energy that the whole mankind generally uses.And electric load is substantially centered by city, industrial area and residential block, power plant is generally built in rivers valley, or coal, oil, Natural Gas Enrichment region etc. are away from user's place.Each grade high-tension line is correspondingly being born the electric power that power plant is sent, and delivers to the task of electric substation in load center or access electrical network through long distance transmission line, makes electric power be able to national product to bring into play huge economic benefit.
In order to improve the security reliability of operation of power networks and to realize maximum economic benefit, rely on high-tension line that each little power plant, electrical network and electric power system are organically coupled together, become maximum electric power system; Each large electric power system is coupled together with superhigh pressure or extra high voltage line again, composition pool, the unified electric power system in the final realization whole nation.The paired running of electric power system is incomparable in economy, technical superiority.High-tension line is being born contacted system, is being connected the effect of capacity exchange between power plant and system, and the contact between electric power system is strengthened.Can find out, the develop rapidly of science and technology and the socialization of production, the capacity in generator single-machine capacity and power plant is increasing.It is concentrated that electrical production is constantly tending towards, between electric power system or the high-tension line that plays contact effect in system between each hinge can get more and more.This is the preferably proof of power industry great development.
Due to the construction development of intelligent grid, the project implementation of high pressure overhead power line on-line monitoring, on tower, equipment does not also have energy-saving and environmental protection, reliable, non-maintaining power supply technique at present.
Summary of the invention
The object of the present invention is to provide a kind of high-tension overhead line ground wire to take out energy power supply technique, to utilize the energy technology of taking out, the electric energy of high-tension overhead line ground wire induction is changed to monitoring equipment power supply on tower, recycled thereby realize line loss, utilize wire induction power taking.This overhead ground wire electricity getting device, can effectively solve monitoring equipment on high voltage iron tower and power and solve the technical barrier that adopts high-voltage conducting wires induction power taking cannot be used for equipment on tower.
To achieve these goals, technical scheme of the present invention is as follows.
A kind of high-tension overhead line ground wire is taken out energy technology; on overhead ground wire, be connected with current/voltage instrument transformer; on current/voltage instrument transformer, be connected with rectification facilities and voltage stabilizing facility; between rectification facilities and voltage stabilizing facility, be provided with energy storage facility, on current/voltage instrument transformer, be also connected with lightning protection device.
Further, described high voltage overhead ground wire comprises conventional ground wire and Ground wire with insulation ocver, and conventional ground wire is in order to record induced current, and Ground wire with insulation ocver is in order to record induced voltage.
Further, described high-tension overhead line, without in situation about having a power failure, requires after design, to determine to adopt current transformer or voltage transformer to take out energy power taking scheme with concrete power taking environment according to supply load, then implements after submitting a report asking for administrative department's examination & approval.
Further, described high-tension line overhead ground wire is taken out energy node, first records current/voltage value, then determines to adopt current transformer or voltage transformer.
Further, described lightning protection Main Function bypass thunder-strike current, protection electricity getting device.
Further, described rectification facilities, energy storage facility are looked burden requirement increase and decrease.
This beneficial effect of the invention is: the loss of high pressure overhead power line ground wire induction electric energy is the major part of line loss.The electric energy of the loss that patent electricity getting device of the present invention is got, be applied to the power supply of monitoring equipment, with solar powered and wire high voltage induction power taking technology comparison, there is significant advantage in advance and the applicability of technology, solve the technical barrier of equipment reliable power supply on tower.
