Description
Technical field
The utility model relates to a kind of down conductors, and in particular to a kind of aluminium pipe structure lightning protection earthing downlead.
Background technique
It is lightning-arrest to draw lower cable for arrester (i.e. lightning conducter) in overhead transmission line lightning protection system between earthed system,
Low impedance path is provided to guide lightning current to greatly in the case where not generating excessive voltage.It is originally traditional aerial
Route using lightning protection earthing line using being bare copper stranded wire, the lightning conducter of one end connection shaft tower upper end of bare copper stranded wire, and the other end
Directly it is connected with the connecting plate of grounding body.High pressure (110kV -750kV) is all used to hand in order to reduce the electric energy loss of transmission line
Galvanic electricity carries out long-distance sand transport, due to the High Level AC Voltage of aerial condutor transmission, will generate induced voltage on lightning conducter,
And be directly connected between lightning conducter and the earth using bare copper stranded wire, just there is induced current to pass through in this way on lightning conducter, exists in this way
Loss (P=I2R) will be produced electricl energy on lightning conducter, so there is consume a large amount of electric energy, wave for existing traditional lightning-arrest downlead
Take the defect of resource, is in addition aoxidized seriously by direct sunlight copper conductor for a long time, so that ground lead resistance is become larger, reduce its transmission
The abilities such as electric current (referring to attached drawing 3).
China Patent Publication No.: 205051318U, publication date: 2016-02-24 discloses the lightning-arrest downlead of chimney and fixes
Device belongs to the technique for fixing of lightning-arrest downlead, and structure includes built-in fitting, fixed dowel and fixation clamp, and described is pre-buried
Part include it is multiple, the concrete wall along chimney is uniformly arranged from top to bottom, and each built-in fitting passes through fixed dowel and coagulation respectively
Tu Bi phase is fixed, and fixation clamp is respectively arranged on front side of each built-in fitting, and the fixation clamp includes preceding plate body, left plate
The left and right side of plate body before body and right panel body, the left plate body and right panel body are separately positioned on, left plate body and right panel body
Rear portion is mutually fixed with built-in fitting, the square cavity that downlead sequentially passes through fixation clamp from top to bottom and built-in fitting surrounds, and from
When top to bottm is at interval of 5-7 built-in fitting, downlead will mutually be welded with built-in fitting.Using being bare copper stranded wire, the one of bare copper stranded wire
The lightning conducter of end connection shaft tower upper end, and the other end is directly connected with the connecting plate of grounding body.In order to reduce the electricity of transmission line
It can be lost and long-distance sand transport is all carried out using high pressure (110kV -750kV) alternating current, since the high pressure of aerial condutor transmission is handed over
Galvanic electricity will generate induced voltage on lightning conducter, and be directly connected between lightning conducter and the earth using bare copper stranded wire, exist in this way
Just there is induced current to pass through on lightning conducter, loss (P=I2R) will be produced electricl energy in this way on lightning conducter, so existing traditional
Lightning-arrest downlead haves the defects that a large amount of electric energy of consumption, waste of resource, is in addition aoxidized for a long time by direct sunlight copper conductor tight
Weight, makes ground lead resistance become larger, and reduces it and transmits the abilities such as electric current.
Utility model content
Utility model aims to solve the defects that the above-mentioned prior art consumes a large amount of electric energy, waste of resource, in addition
It is aoxidized seriously by direct sunlight copper conductor for a long time, ground lead resistance is made to become larger, reduce the problem of it transmits the abilities such as electric current,
A kind of aluminium pipe structure lightning protection earthing downlead is provided.
The technical scheme adopted by the utility model to solve the technical problem is as follows: under a kind of aluminium pipe structure lightning protection earthing draws
Line, including aluminum pipe, semi-conductive layer, insulating layer, outer conductor layer, band, aluminium-plastic tape and oversheath, the aluminum pipe are extruded with outside
Semi-conductive layer, the outside packet of the semi-conductive layer are equipped with insulating layer, and the outside packet of the insulating layer is equipped with by outer conductor layer, leads outside
The outside packet of body layer is equipped with band, and the outside packet of band is equipped with aluminium-plastic tape, and the outside packet of aluminium-plastic tape is equipped with oversheath,
The outer conductor layer includes several outer conductor, and outer conductor single layer is packaged in the outside of insulating layer, and outer conductor abuts between each other.
The utility model is improved from Cable Construction Design, it is lightning-arrest draw lower cable can be in overhead transmission line by can be suitable when being struck by lightning
Lightning current is introduced the earth by benefit ensures that transmission line of electricity can cross safety and stability, while also guaranteeing that lightning conducter does not generate sense when day-to-day operation
Electric current is answered, electric energy loss is reduced；In addition using longitudinal wrap aluminium-plastic tape can effectively outside moisture enter cable internal layer, prevent
The generation of insulating layer " water tree ", it is ensured that insulating layer is run reliably and with long-term.
Preferably, the internal diameter of the aluminum pipe is at least three times of outer conductor diameter.
Preferably, the thickness of the insulating layer, aluminum pipe and oversheath successively reduces.
Preferably, the internal diameter of the aluminum pipe is at least 3 times of aluminum pipe thickness.
