Description
Technical field
The present invention relates to electric system overhead distribution more particularly to a kind of fixed limits based on narrowband technology of Internet of things
Fitting under depressor discharge path.
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 later period the 1960s
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 releasing, is just widelyd popularize, and itself can continue to extend, energy and narrowband
Internet of Things combines, and is formed " the integrated voltage limiter based on narrowband technology of Internet of things ", realizes communication function.But its lower fitting is
Between grading ring and lower fitting, lower fitting height is put between 30-50mm for simple metal structure, heavier-weight, and discharge path
Power path can not be unique.
Summary of the invention
The technical problems to be solved by the present invention are: being directed to power distribution network 10-35kV system Broken of Overhead Insulation Lines By Lightning
Problem can effectively prevent insulated conductor to damage because of Lightning Over-voltage, and reduce integrated voltage limiter weight, fixed electric discharge road
Diameter.
To solve the above problems, the technical scheme adopted by the invention is that: it provides a kind of based on narrowband technology of Internet of things
Fitting under fixed voltage limiter discharge path, including lower fitting ontology, rubber sleeve, screw rod, nut；Wherein rubber sleeve is socketed in lower gold
Have the outside of ontology, forms integral structure；Lower fitting ontology is connect by screw rod with route cross-arm, standby with cross-arm by nut
Tightly.
As a preferred solution, lower fitting ontology upper end exposed metal/bare metal height is 8-mm.
As a preferred solution, rubber sleeve is formed using silicon rubber one-step mould, and there are 1 umbrella leaf, the umbrella in outside
Thunder discharge path can be limited at the upper end exposed metal/bare metal of grading ring and lower fitting ontology by leaf, and arcing distance is fixed.
As a preferred solution, umbrella leaf diameter is 90-100mm, and rubber sleeve height is 30-40mm.
As a preferred solution, rubber sleeve with a thickness of 3-5mm.
Lower fitting ontology upper end therein exposed metal/bare metal height is 8-12mm.
Lightning stroke flashover can be prevented hitting into thunder and lightning discharges after puncturing rubber sleeve with lower fitting.

Specific embodiment
Specifically describe a specific embodiment of the invention referring to the drawings:
Fitting under fixation voltage limiter discharge path described in the present embodiment based on narrowband technology of Internet of things, integrated pressure limiting
Device is composed of integrated voltage limiter ontology 5 and lower fitting, and integrated voltage limiter is mounted on one by lower fitting and cross-arm
It rises, is fixed to integration voltage limiter.
Fitting is composed of lower fitting ontology 1, rubber sleeve 2, screw rod 3 and nut 4 under integrated voltage limiter；Outside rubber
Set 2 is socketed on lower fitting 1, and lower fitting 1 is mounted on cross-arm by screw rod 3, and standby tight by nut 4.
For a certain dimensional drawing of fitting as shown in figure 3, total height is 98mm, 3 length of screw rod is 46mm under integrated voltage limiter,
Height is 12mm at the electric discharge that top retains, and being socketed the diameter at rubber sleeve 2 is 34mm.
Under integrated voltage limiter fitting rubber sleeve dimensional drawing as shown in figure 4, rubber sleeve ontology diameter be 44mm,
Height is 30mm, and the diameter of a umbrella leaf is 90mm, umbrella cover with a thickness of 5mm.
The present invention is set with rubber sleeve at lower fitting, can reduce product weight, and be capable of fixing discharge path, beauty can
It leans on, cost performance is high.The size of fitting and rubber sleeve only illustrates in the present specification under integrated voltage limiter of the invention
Preferred embodiment is not to limit it.
