Description
Technical field
The power cable the present invention relates to a kind of anti-theft high-voltage is transmitted electricity, belongs to high voltage power transmission technical field.
Background technology
Wires and cables industry is second largest industry, product variety Service Efficiency and the state that China is only second to automobile industry
Interior market share is all more than 90%.Worldwide, the Chinese electric wire gross output value has exceeded the U.S., becomes
For the in the world first big electric wire manufacturing country.Along with Chinese wires and cables industry high speed development, creation of new enterprise
Quantity constantly rises, and industry overall technology level is largely increased.With the fast development of national economy, make
Increasing for the consumption and range of the power cable of national economy aorta.Power cable is for transmitting
Cable with distribution electric energy.It is usually used in Urban Underground electrical network, the lead line of electric station, the inside of industrial and mining establishment
Power and cross river, excessively extra large submarine transmission line.In power circuit, the proportion shared by power cable just gradually increases
Plus.Power cable is to produce in order to transmit and to distribute the cable of high-power power in the basic routing line of power system
Product, including the power cable of 1-500KV and the various insulation of any of the above electric pressure.Power cable
Basic structure is made up of core (conductor), insulating barrier, screen layer and protective layer four part.Core is electric power electricity
The current-carrying part of cable, for conveying electric energy, is the major part of power cable.Insulating barrier is by core and the earth
And be electrically isolated from each other it is ensured that electrical energy transportation between out of phase core, it is can not in power cable structure
The ingredient lacking.Screen layer, because the electric current ratio that electric power cable passes through is larger, can produce magnetic around electric current
, in order to not affect other element, so plus screen layer can this electromagnetic-field-shielded in cable.Protection
The effect of layer is the intrusion protecting power cable from introduced contaminants and moisture, and prevents external force from directly damaging electricity
Power cable.
Power cable can be divided into core and overcoat from structure, and (overcoat refers to insulating barrier, screen layer and protection
Layer) two large divisions, the core positioned at innermost layer is used for transmitting electric energy, and the overcoat being rolled in outside core has multilamellar
Structure, realizes the functions such as shielding, insulation, anti-external force destruction respectively.In high pressure and above defeated, power distribution network, by
Higher in voltage, theft live electric cable often can lead to thief's injures and deaths, and therefore, present robber steals power circuit
It is not the copper material aiming at wire, occur in that the stolen thing of a lot of 10kV power cable overcoats in this year
Part.Because cable laying is hidden, and be not provided with supervising anti-system, thus cable shield stolen do not cause have a power failure
And short circuit accident be difficult be found, but leave very big potential safety hazard.After some cable shield are stolen,
Although temporarily not occurring to have a power failure or personnel casualty accidentses, cable insulation degree of protection declines to a great extent, and operates
Voltage, lightning surge, harmonic wave overvoltage, personnel trample, damaged by rats all will trigger short circuit, a certain mutually short-circuit quick-fried
The fried a plurality of feeder line often causing laying in one ditch is simultaneously short-circuit, cause large-area power-cuts it can be seen that, steal
Thief has buried the serious potential safety hazard in many places to power system.Because the cable after a plurality of overcoat is stolen buries
In underground, power department does not have the security situation of special monitoring of equipment cable so far it is impossible to learn power cable
Overcoat be destroyed, thus can not adopt remedial measures in time, make power system and periphery personnel and environment
Safety is seriously threatened.
Existing high-power three core power cable radiating effects are very poor, how to solve the radiating of high-power electric cable and ask
Topic is very valuable research topic.
By above description, it can be found that just can stand when stealing power cable overcoat for robber
Carve and know have theft being a problem highly studied.
Content of the invention
The technical problem to be solved in the present invention is：Steal the protection of high voltage power transmission power cable for current robber
It is difficult to be found during layer, leave very big potential safety hazard to transmission line of electricity, at present can't be anti-in robber's theft

The present invention is capable of stealing the principle explanation of point monitoring：No matter robber steals the core of power cable, also
It is the overcoat (overcoat includes insulating barrier, screen layer and protective layer) of theft power cable, then be required for
First destroy protective layer, once destroy protective layer to be bound to destroy wire.Because the two ends of wire are all to connect respectively
First DC source and the positive pole of the second DC source, and the voltage of the first DC source and the second DC source
Equal, so electric current will not be produced in wire, once if robber's theft power cable, first wire can be cut off,
Cutting off wire in a flash using metal shears, be equivalent to cut off a little pass through metal shears and human body grounding (by
Protective layer in power cable typically employs a lot of linen-cottons and elastomeric material etc., so being difficult to destroy, because
This robber must use metal shear, and metal shears are usually naked function).At this time, former
The wire first not producing electric current can produce in a flash electric current at this, and the sense of current is by the first DC source, second straight
Stream positive source points to cuts breakpoint direction.The moment cut off, the first current detecting unit and the second current detecting list
Unit all can detect electric current, after field controller unit detects wire generation electric current, at once to remote controller
Unit sends alarm signal, after remote controller unit receives alarm signal, controls alarm unit to send acousto-optic report
Alert.The wire within power cable protective layer of the present invention, is equivalent in a flash ground connection cut off, according to leading
The resistivity of line, line footpath and the voltage of the electric current detecting and DC source, can be easy to calculate cut off
The positional distance of point.Theft is had to occur so the present invention not only can know the very first time, simultaneously can first
Time Calculation goes out to steal place.
