Background technology
Lightning overvoltage on distribution line is hit insulated overhead line by thundercloud discharge and produces, because distribution line is exhausted
Edge level is low, phase spacing is little, easily causes single-phase and heterogeneous flashover；Insulated overhead line is sent out because of thunderbolt
After raw disruptive discharge over the ground, the discharge breakdown on wire insulation, puncture place is near line insulator two
Side random distribution.After lightning impulse flashover, the power frequency short circuit current continued can rise along thunder discharge passage
Arc burns, and the power frequency continued flow starting the arc is burnt.When thunderbolt causes circuit biphase or three relative ground circuits, relatively
Electric arc forms alternate electric arc by cross-arm, and phase fault current amplitude reaches a few kilo-ampere to tens kilo-amperes, arc root
Temperature rises to thousands of degree, the pulling force that wire deadweight produces in addition, and wire instant melting disconnects.Lightning-caused breaking
The event of the damage of accident and insulator is susceptible to, and insulating properties is the most bad, and the reliability of supplying power allocation is not
High.
Utility model content
The purpose of this utility model is to provide a kind of tension-resistant rod to fix external series gap Zinc-Oxide Arrester, to solve
The problem proposed in above-mentioned background technology.
For achieving the above object, this utility model provides following technical scheme: a kind of tension-resistant rod fixes outer room
Gap Zinc-Oxide Arrester, including lightning arrester body, the lower end of described lightning arrester body is provided with fixing end, keeps away
The upper end of thunder device body connects leaded, and the side, top of described lightning arrester body connects electrode sleeve, electricity
The upper end of pole set is provided with sparking electrode, and the side, upper end of lightning arrester body also is provided with sparking electrode, described electricity
The outside of pole set is provided with protective umbrella, and the outside of described lightning arrester body is cased with insulating sheath, insulating protection
The outside spacers of set is provided with gamp and umbellule.
Preferably, described electrode sleeve upper end is provided with sparking electrode and the electric discharge that lightning arrester body upper end is provided with
The position of electrode is corresponding.
Preferably, described insulating sheath is silica gel material.
Preferably, described sparking electrode is that stainless steel is made.
Compared with prior art, the beneficial effects of the utility model are: this tension-resistant rod fixes external series gap oxidation
Zinc spark gap can effectively protect 10kV transmission line insulator aerial line, naked aluminum conductor from breaking that thunder and lightning causes
Line, the protection flashover that causes from overvoltage of insulator or puncture, insulating properties is good, can efficiently reduce
Lightning-caused breaking accident and the damage of insulator, and easy for installation；Run and safeguard simple, improve efficiently
Reliability of Power Supplying Net Work.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
In figure: 1 lightning arrester body, 2 fixing ends, 3 lead-in wires, 4 electrode sleeves, 5 protective umbrellas, 6 electric discharge electricity
Pole, 7 insulating sheaths, 71 gamps, 72 umbellules.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, to the technology in this utility model embodiment
Scheme is clearly and completely described, it is clear that described embodiment is only this utility model one
Divide embodiment rather than whole embodiments.Based on the embodiment in this utility model, this area is common
The every other embodiment that technical staff is obtained under not making creative work premise, broadly falls into this
The scope of utility model protection.
Referring to Fig. 1, this utility model provides a kind of technical scheme: a kind of tension-resistant rod fixes external series gap oxidation
Zinc spark gap, including lightning arrester body 1, the lower end of lightning arrester body 1 is provided with fixing end 2, and spark gap is originally
The upper end of body 1 connects leaded 3, and the side, top of lightning arrester body 1 connects electrode sleeve 4, electrode sleeve
The upper end of 4 is provided with sparking electrode 6, and sparking electrode 6 is made for stainless steel, can efficiently reduce thunderbolt
Line-outage contingency and the damage of insulator, and easy for installation, the side, upper end of lightning arrester body 1 also is provided with putting
Electricity electrode 6, sparking electrode 6 that electrode sleeve 4 upper end is provided with and the electric discharge that lightning arrester body 1 upper end is provided with electricity
The position of pole 6 is corresponding, and owing to the two end electrodes of external series gap is fixed, its electrical distance is fixed, will not
Change brought electrical network along with the swing of wire unstable, extenal fixation clearance electrode with simple in construction,
With whole lightning protector integrator, the outside of electrode sleeve 4 is provided with protective umbrella 5, and small design protective umbrella 5 can
The effect of arc protection when playing electric discharge, the outside of lightning arrester body 1 is cased with insulating sheath 7, insulating protection
Set 7 is silica gel material, it is ensured that good insulating properties, the outside spacers of insulating sheath 7 is provided with greatly
