Description
Technical field
This patent is related to the non-binding of electric system overhead distribution more particularly to a kind of insulated conductor of overhead line
Formula integration voltage limiter can effectively prevent insulation to lead for power distribution network 10-35kV system Broken of Overhead Insulation Lines By Lightning problem
Line is damaged because of Lightning Over-voltage, and simplifies mounting means.
Background technique
In power distribution network, solve the corridor and safety problem that bare conductor can't resolve using insulated conductor, with cable
It compares, fastly, advantage is fairly obvious for, construction with low investment using insulated conductor.Developed countries from the later period sixties 20th century
Gradually adopt suspended insulated guide wire.But insulated conductor also has the weakness of its own, i.e. lightning-caused breaking problem, and so-called lightning stroke must break
Line.Therefore, it is necessary to properly settle lightning-caused breaking problem.
According to the mechanism of insulated conductor breakage caused by lightning stroke, the corresponding precautionary measures have " dredge and block " two ways.It " dredges
Lead " it is exactly so that power frequency arc arc root is shifted or is fixed on special fitting the insulated conductor part bare wire near insulator
Burning, to protect conducting wire from burn.For example, at insulator and wire coupling stripping insulation layer, using arc protection type
The insulated conductor of insulator two sides is removed one section of insulating layer and installs preventing arc wire clamp additional by wire clamp.The mode of " leading-type " operates letter
Single, small investment, but conducting wire is locally exposed, and there are sealings and insulation defect." blocking " is exactly to prevent power frequency continued flow after lightning stroke flashover
The starting the arc.For example, using current-limiting arc-extinguishing angle, i.e., with ring-like external series gap metal oxide arrester of connecting.It is " stifled compared to " leading-type "
The mode better protecting effect of plug ", the disadvantage is that construction is relative complex, higher cost.
It is proposed a kind of Novel lightning-proof product currently on the market, " integrated voltage limiter " its collection insulator and arrester function
In one, structure is simple, easy for installation, from release, is just widelyd popularize, but the connection of itself and conducting wire is still using old-fashioned
Binding-type installation, need to additionally prepare wiring, and installation is inconvenient.
Summary of the invention
According to the above-mentioned deficiencies of the prior art, the technical problems to be solved by the present invention are: providing a kind of aerial condutor use
Non- binding-type integration voltage limiter, overcome existing technological deficiency, be suitble on 0-35KV suspended insulated guide wire.
The technical scheme adopted by the invention is that: a kind of non-binding-type integration voltage limiter of aerial condutor, including pressure
Plate, connecting screw, upper fitting, integrated voltage limiter, standby tight nut；Integrated voltage limiter top be equipped with upper fitting, pressing plate with it is upper
Fitting is connected by connecting screw, and by standby tight nut that connecting screw is standby tight, pressing plate and upper fitting clamp intermediate conducting wire.
As a preferred solution, pressing plate is impacted using aluminum component, radian can with conducting wire is intact is engaged,
The thickness of the aluminium is in 3-5mm.This size is to facilitate forming that can reach again to cooperate beautiful requirement, and pressing plate with former upper fitting 3
Radian can be according to the difference of the diameter of conducting wire, any change size reach close-fitting effect.
As a preferred solution, connecting screw uses M8*40 size.
As a preferred solution, to reach compression conducting wire, fitting is made to link together with conducting wire.
As a preferred solution, upper fitting is equipped with groove, can place conducting wire, and groove surrounding is fillet, is prevented
Conducting wire damage when waving.It is equipped with screw thread in upper fitting upper end, the screw thread can cooperate with pressing plate, suppress conducting wire.
The invention has the advantages that: connecting screws to use M8*40 size, and the cooperation that this size can be intact is in integrated pressure limiting
On the fitting of device, and the mechanical structure of former fitting will not be caused badly damaged, upper fitting nut is for distance that is next, leaving
It is shorter, it is not easy to hang foreign matter, the company's of causing electricity.It is suitble to the non-binding-type used on 10-35KV suspended insulated guide wire integrated
Voltage limiter, the connection with conducting wire use non-binding-type, standby tight by carrying out after pressing plate compression conducting wire to screw rod, and screw size
It is fixed, it is not easy to hang foreign matter.
Detailed description of the invention
Fig. 1 is the vertical mounting structure schematic diagram of this patent；
In figure: 1, pressing plate；2, connecting screw；3, upper fitting；4, nut；5, conducting wire；6, integrated voltage limiter.
Specific embodiment
Specifically describe the specific embodiment of patent referring to the drawings.
As shown in Figure 1, the integrated voltage limiter of insulated conductor of overhead line, core structure is upper fitting 3 and pressing plate 1,
Pressing plate 1 forms compressing structure with integrated voltage limiter 6 by connecting screw 2, is carried out by standby tight nut 4 to connecting screw 2 standby
Tightly, to compress conducting wire 5, fitting 3 is made to link together with conducting wire 5.
According to the mode, in the present embodiment, bottom radius of circle is provided on the upper fitting 3 of integrated 6 high-voltage end of voltage limiter
The groove to match with insulated conductor radius, insulated conductor 5 are erected in the groove of fitting 3, wherein the groove radius of pressing plate 1
For 19mm, can closely be compressed from the conducting wire 5 of 20-50mm diameter.Wherein the width of pressing plate is 24mm, length 61mm, thickness
For 3mm, pitch of holes 44mm, for no-float, which be can be adjusted according to the actual situation, and specific installation method is pressed
It is installed according to 10KV insulator neck hypodesmus or 10KV insulator top hypodesmus.
Upper 3 high-voltage end of fitting is equipped with groove, can place conducting wire, and groove surrounding is fillet, prevents conducting wire 5 from waving
When damage.It is equipped with the screw thread of M8 in upper 3 upper end of fitting, can cooperate with pressing plate 1, suppress conducting wire 5.
Integrated voltage limiter of the invention only illustrates some preferred embodiments in the present specification, is not to limit it.
Inventive concept and spirit can make other variations or modification to patented technology personnel in structure according to the present invention, but should belong to
In protection scope of the present invention.
