Description
Technical field
The utility model is related to direct lightning strike lightning arrester, more particularly to a kind of combination disc type Multiple level arrester.
Background technology
Modern times 6~35kV overhead distributionnetworks are due to dendritic network structure, and distribution face is big, and thunderstruck probability is high, and
Power distribution network dielectric level is relatively low, is easiest to occur lightening hazard.
According to statistics, the sudden strain of a muscle that built on stilts radar overhead distributionnetwork generation lightening hazard is mainly insulator is ironed or exploded, and therefore, is adopted
The lightning damage of insulator is prevented to be very important with disc type Multiple level arrester.
Utility model content
The purpose of this utility model is that a kind of combination disc type Multiple level arrester of offer, and its lightning current is more by disc type
Gap arrester is guided to greatly, it is to avoid lightning current flows through high voltage overhead lines insulator, while multiple minim gaps and main gap
Coordinate, can effectively extinguish the power frequency arc between high voltage overhead lines and ground.
What the purpose of this utility model was realized in：
First, single disc type Multiple level arrester
Single disc type Multiple level arrester includes glass insulator, Multiple level electrode, fixed compound inslation band, main gap
Ball discharge under upper ball discharge and main gap；
Multiple level electrode is covered by fixed compound inslation band in the outer of glass insulator, the two of Multiple level electrode
End is connected on main gap ball discharge under ball discharge and main gap.
2nd, multiple disc type Multiple level arresters
Multiple disc type Multiple level arresters are kept away including the be sequentially connected in series the-the 1st from top to bottom, 2 ... N disc type Multiple levels
Thunder device, N is natural number, 1≤N≤6.
Working mechanism of the present utility model：
When overhead high-voltage wire is by being struck by lightning, high voltage is produced at insulator two ends, when high voltage is kept away more than disc type Multiple level
Thunder device voltage protection level value and less than insulator discharge voltage when, disc type Multiple level arrester intermediate gap produce ionization electricity
Arc, forms conducting loop, lightning current is introduced into underground.
The Multiple level being made up of stainless shot and 3 main gaps, can be to overhead high-voltage wires after lightning current is introduced into underground
Power frequency continued flow electric arc between ground enters horizontal blanking, it is ensured that power supply safety.
The utility model has following advantages and good effect：
1. lightning strike protection level is low, through-current capability is big, can bear the attack of direct lightning strike；
2. unique high arc-rupturing capacity, protects the safety of transmission line of electricity；
3. it is simple in construction, small volume, lightweight；
4. it is non-maintaining in easy for installation, use；
5. it can run and use in rugged environment, not be afraid of pollution.

Embodiment
Describe in detail with reference to the accompanying drawings and examples：
1st, single disc type Multiple level arrester
1）It is overall
Such as Fig. 1, single disc type Multiple level arrester includes glass insulator 1, Multiple level electrode 2, fixed compound inslation bag
Ball discharge 5 under ball discharge 4 and main gap on band 3, main gap；
Multiple level electrode 2 is covered by fixed compound inslation band 3 in the outer of glass insulator 1, in Multiple level electrode 2
Two ends be connected on main gap ball discharge 5 under ball discharge 4 and main gap.
2）Functional part
（1）Glass insulator 1
Glass insulator 1 is a kind of conventional insulator of transmission line of electricity.
（2）Multiple level electrode 2
Multiple level electrode 2 is arranged by some spherical or cylindrical conductor by 0.5~2mm spaced linears, and conductor is by copper or steel
Process；
Multiple level system is constituted with interelectrode the air gap, plays conducting electric current and blow-out.
（3）Fixed compound inslation band 3
It is made up of silicon rubber, in strip, is wrapped in the outside of Multiple level electrode 2, plays support and connection function.
（4）Ball discharge 5 under ball discharge 4, main gap on main gap
It is made up of cylindrical conductor, conductor is processed by copper or stainless steel；
Between keep 40-60mm gap.
Play conducting electric current and auxiliary blow-out.
2nd, multiple combination disc type Multiple level arresters
Such as Fig. 2, multiple combination disc type Multiple level arresters include the be sequentially connected in series the-the 1st from top to bottom, 2 ... N disks
Formula Multiple level arrester 10,20 ... N0, N are natural number, 1≤N≤6.
On the insulator of high voltage transmission line, the utility model is connected in parallel on insulator two ends, upper end main gap ball discharge
With transmission pressure formation 50mm the 1st main gap；Bottom main gap ball discharge installs cross bar (metal angle) with insulator
50mm the 3rd main gap is formed, the ball discharge of main gap up and down of temporary location constitutes 2 respectively at about 2 installation units
Discharge main gap, and 4 main gaps constitute Multiple level electrode combination into portable protective gaps with multiple stainless steel steel balls.
When power line cable is attacked by thunder and lightning, high voltage is produced between power line cable and installation cross bar, is combined
The breakdown voltage level of protection of disc type Multiple level arrester is less than the breakdown voltage level of protection of insulator, combines disc type Multiple level
Arrester punctures first, and air ionization formation arc short circuit between gap, lightning current is released to underground along this passage；Lightning current disappears
Afterwards, because the energy dissipating of Multiple level is acted on, the power frequency continued flow electric arc between gap is interrupted, and is disappeared, and power frequency continued flow disconnects
Application method
1st, according to bus voltage grade, 3 disc type Multiple level arrester units are combined into 35kV combined type Multiple levels
Arrester（Each disc type Multiple level arrester cell operation voltage 15kV）；
2nd, combined arrester rotating hanging at the insulator two ends of transmission line of electricity, formation is connected in parallel；
3rd, disc type Multiple level is chosen to install, the width of 4 main gaps of adjustment is 50mm.
