3 Phase Lightning Arrester Din Rail Mounted IEC Standard For Spd Protection

 

 

Definition
Lightning arrester: An electrical appliance used to protect electrical equipment from high transient overvoltage hazards during lightning strikes and to limit the duration of the renewal current, and often also the renewal current amplitude. Lightning arrester is sometimes also called overvoltage protector, overvoltage limiter. As shown in Figure 1 is a lightning arrester.

 

 

 

 

Normal service conditions:

 

1. The ambient temperature: -40°C ~+40°C

2. The altitude above sea level :not exceed 1000-2000m (the altiplano area should be indicated when order)

3. Earthquake intensity: not higher than 7 degrees;

4. Maximum wind velocity :less than 35m/s.

5. The filthy area should be given clear indication.

 

Feature:

 

The zinc oxide surge arrester is the most advanced over-voltage protector in the world. Due to make the resistor disc of core component mainly adopt zinc oxide arrester. Compared with the conventional siliconcarbide arrester, this prescription of the product improves greatly the volt-ampere characteristics of the resistor disc and increase through- current capability at over-voltage so as to bring a rad local-changes for the characteristics of the arresters.

 

 

Seven characteristics.


A, zinc oxide lightning arrester through-current capacity of large
This is mainly reflected in the arrester has the ability to absorb various lightning overvoltage, frequency transient overvoltage, operating overvoltage. Chuantai production of zinc oxide lightning arrester through-current capacity is fully consistent with or even higher than the requirements of national standards. Line discharge level, energy absorption capacity, 4/10 nanosecond high current impact withstand, 2ms square wave through-current capacity and other indicators have reached the domestic leading level.


Second, the zinc oxide arrester has excellent protection characteristics
Zinc oxide arrester is an electrical product used to protect various electrical equipment in the power system from overvoltage damage, with good protection performance. Because the non-linear voltammetric characteristics of zinc oxide valve piece is very good, making only a few hundred microamps of current through the normal working voltage, easy to design into gapless structure, so that it has good protection performance, light weight, small size characteristics. When the overvoltage intrusion, the current flowing through the valve piece rapidly increases, while limiting the magnitude of the overvoltage, releasing the energy of the overvoltage, after which the zinc oxide valve piece returns to the high resistance state, so that the power system works normally.


Third, the sealing performance of zinc oxide surge arrester is good
Arrester components using aging performance, good gas tightness of high-quality composite jacket, the use of control seal compression and increase the amount of sealant coating and other measures, ceramic jacket as sealing materials to ensure reliable sealing, so that the arrester performance is stable.


Fourth, the mechanical properties of zinc oxide surge arrester
Mainly consider the following three factors.
(1) the seismic force withstood.
(2) the role of the arrester on the maximum wind pressure
(3) the top of the arrester to withstand the maximum allowable pull of the wire.


Five, zinc oxide arrester of good decontamination performance
Gapless zinc oxide arrester has a high fouling resistance performance.
At present, the national standard stipulates the creepage ratio distance level as follows
(1) Level II medium fouling area: creepage ratio distance 20mm/kv
(2) Class III Heavy fouling area: creepage ratio distance 25mm/kv
(3) Level IV extra heavy fouling area: creepage ratio 31mm/kv


Sixth, the high operating reliability of zinc oxide surge arrester
The reliability of long-term operation depends on the quality of the product, and whether the product selection is reasonable. Impact on the quality of its products are mainly the following three aspects.
A The rationality of the overall structure of the arrester.
B The voltammetric characteristics and aging resistance of zinc oxide valve piece
C The sealing performance of the arrester.


Seven, industrial frequency withstand capacity
As the power system, such as single-phase grounding, long line capacitance effect and dump load and other reasons, will cause the rise of the frequency voltage or generate a higher amplitude transient overvoltage, lightning arrester has a certain time to withstand a certain frequency voltage rise capacity.
