Description
Technical field
The present invention relates to a kind of high voltage power transmission power cable, belong to high voltage power transmission technical field.
Background technology
Along with the fast development of national economy, as the consumption of power cable of national economy aorta with use model
Enclose increasing.Power cable is the cable for transmitting and distribute electric energy.It is usually used in Urban Underground electrical network, sends out
The lead line in power station, the in-line power of industrial and mining establishment and the submarine transmission line in mistake river, excessively sea.At power circuit
In, the proportion shared by power cable is just gradually increased.Power cable be in the basic routing line of power system in order to
Transmission and the cable product of distribution high-power power, including 1-500KV and any of the above electric pressure,
The power cable of various insulation.
The basic structure of power cable is made up of core (conductor), insulating barrier, screen layer and protective layer four part.
Core is the current-carrying part of power cable, is used for carrying electric energy, is the major part of power cable.Insulating barrier is
To be electrically isolated from each other between core and the earth and out of phase core, it is ensured that electric energy carries, be electric power electricity
Indispensable ingredient in cable structure.Screen layer, because the current ratio that electric power cable passes through is relatively big, electric current
Around can produce magnetic field, in order to not affect other element, so add screen layer can this electromagnetic-field-shielded
In cable.The effect of protective layer be protection power cable from introduced contaminants and the intrusion of moisture, and outside preventing
Power directly damages 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, it is positioned at the core of innermost layer for transmitting electric energy, the overcoat being rolled in outside core has multilamellar
Structure, realizes the functions such as shielding, insulation, anti-external force destruction respectively.At high pressure and above defeated, power distribution network, by
Higher in voltage, theft live electric cable often can cause thief's injures and deaths, and therefore, present robber steals power circuit
It not the most the copper material aiming at wire, occur in that a lot of 10kV stolen thing of power cable overcoat in this year
Part.Owing to cable laying is hidden, and it is not provided with supervising anti-system, therefore cable shield is stolen does not cause power failure
And short circuit accident be difficult to be found, but leave the biggest potential safety hazard.After some cable shield are stolen,
Although temporarily not occurring to have a power failure or personnel casualty accidents, but cable insulation degree of protection declining to a great extent, and operates
Voltage, lightning surge, harmonic wave overvoltage, personnel trample, damaged by rats, all will trigger short circuit, the short circuit of a certain phase
Blast, often causes a plurality of feeder line short circuit simultaneously of laying in one ditch, causes large-area power-cuts, it can be seen that,
Robber has buried, to power system, the potential safety hazard that many places are serious.Owing to the cable after a plurality of overcoat is stolen buries
Ensconcing underground, power department does not has the security situation of special monitoring of equipment cable so far, it is impossible to learn electric power electricity
The overcoat of cable is destroyed, thus can not adopt remedial measures in time, makes power system and periphery personnel and environment
Safety by serious threat.
By above description, it appeared that just can stand stealing power cable overcoat when for robber
Carving the place finding and navigating to steal is the problem highly studied.
The core space availability ratio of existing four core power cables is the highest, causes the diameter of whole power cable very
Slightly.
