Utility model content
The purpose of this utility model is that going out in view of the deficienciess of the prior art, providing a kind of semi-enclosed double back wash
Arc insulator.The device possesses preferable arc extinguishing validity and durability.
To achieve the goals above, the technical solution of the utility model is as follows:
A kind of semi-enclosed double back wash arc extinguishing insulator, including be fixedly mounted on cross-arm or make somebody a mere figurehead by connection gold utensil and lead
Insulator body, top electrode and lower electrode on line；It is hollow structure inside the insulator body, and in insulator body
Bosom position is also longitudinally equipped with partition, and the inner space of insulator body is separated into two groups of recoil perfusions and gone out by the partition
Arc channel, the partition are equipped with wall electrode；A recoil is fixedly mounted in the upper end in the recoil perfusion arc extinguishing channel in left side to go out
Arc component, lower end are the recoil spout for being extended or being extended vertically downward to insulator body side；On right side
The upper end in recoil perfusion arc extinguishing channel is the recoil spout being extended to insulator body side, and lower end fixed installation one is anti-
Rush arc extinguishing component；The recoil arc extinguishing component and top electrode of insulator body upper end are electrically connected, the recoil of insulator body lower end
Arc extinguishing component and lower electrode are electrically connected.
The utility model further illustrates that the recoil arc extinguishing component is mainly made of recoil tube and arrester；Described
Recoil tube is open at one end, arrester is fixedly mounted in the other end, and the arc extinguishing component that makes to recoil becomes inner hollow, open at one end, another
Hold closed semiclosed pipe fitting；The arrester and top electrode or lower electrode are electrically connected.
The electrode and arrester be all made of strong electric conductivity metal or nonmetallic composition, can pilot arc enter recoil
It is perfused in arc extinguishing channel；The recoil tube is constituted using the nonconductive metal material of high-intensitive, strong pressure resistance.
The utility model further illustrates that the recoil tube opening is equipped with and leads arc ring.Arc ring is led using strong electric conductivity
Metal or nonmetallic composition, by with wall electrode cooperate, pilot arc go to the other side recoil perfusion arc extinguishing channel.
The utility model further illustrates that the outer surface of the insulator body is equipped with skirt.Setting skirt can increase
Strong creepage distance avoids electric arc creeping discharge.
The utility model further illustrates that the wall electrode, which uses, leads arc electrode slice or compression arc-extinguishing tube or recoil
Pipe.Setting wall electrode can effectively disperse arc energy, and electric arc is made to be easier to extinguish.
The utility model further illustrate, it is described to insulator body side be extended recoil spout opening to
Lower inclination.
Working principle of the utility model is:
On the transmission line by the utility model installation, the electric arc generated when lightning stroke shaft tower or lightning conducter is introduced into insulation
In substring inside, prevent in insulator chain outer surface flashover；Electric arc can be pulled into insulation by top electrode or lower electrode
Inside substring, since recoil perfusion arc extinguishing channel is very thin, coarse thunder and lightning electric arc can shape when entering and recoiling perfusion arc extinguishing channel
Become elongated electric arc, arc extinguishing channel is perfused full of entire recoil, recoil perfusion arc extinguishing channel can generate active force most to electric arc
It will form the quick-fried effect of pressure eventually, block passing through for subsequent electric arc, truncation is generated to electric arc；The electricity in recoil perfusion arc extinguishing channel is entered
Arc is by leading the recoil tube being pulled into recoil arc extinguishing component of arc ring or arrester, when electric arc enters recoil from arc ring is led
Guan Shi will receive the limitation of recoil tube wall since electric arc is that have elastically-deformable plasma, and electric arc enters recoil tube beginning
When, density, speed, temperature increase, and lead to the increase of overpressure, and final generate presses quick-fried effect, electric arc impact recoil bottom of the tube
Arrester, electric arc blocking recoil bottom of the tube by reversed elastic force, the direction of advance of most of electric arc occurs 180 ° and changes
Become；For the electric arc to rebound back since speed, density, pressure are bigger, cavity effect acts on outer electric arc in inlet, leads to recoil tube
Electric arc at port generates truncation, until extinguishing electric arc.In addition, if after the arc extinguishing that once recoils still residual arc, leading arc
Under the collective effect of ring and wall electrode, the remaining residual arc that do not extinguish can be drawn into the semiclosed recoil perfusion in the other side
Recoil arc extinguishing component in arc extinguishing channel carries out recoil arc extinguishing movement again, thoroughly extinguishes electric arc.
The utility model has the advantage that and has the beneficial effect that:
1. the utility model can constrain and manage arc path, electric arc can introduce arc extinguishing channel, eliminate wandering
Harm, improve security performance.
2. the utility model can directly replace the insulator chain on transmission line of electricity, not only has original insulation function, also
With lightning protection arc-suppression function, use scope is wide, is not influenced by wire arrangements, shaft tower tower, polar effect
3. the utility model effectively prevent insulator chain outer surface flashover problem, power equipment tripping rate with lightning strike is reduced, is protected
Electric power facility is protected, electric network reliability is improved, is conducive to electricity safety production.
