Life and property cause damage.In particular with the continuous improvement of people's quality of life, a large amount of household electrical appliance enter commonly old
The family of the common people, this just puts forward higher requirement to the power utilization environment of present family.
In order to prevent from launch aing surprise attack the generation of phenomenon, lightning-protection module is set generally in distribution box, forms power lightning protection box.At present
The lightning-protection module commonly used on the market generally includes varistor and discharge tube.For improving its lightning protection effect, varistor typically by
Four pieces of varistor assemblies are in series.Meanwhile, if outer net voltage rises, amplitude is higher and the persistent period is longer, varistor
Can be punctured thus being in low resistive state by transient overvoltage, thus guiding discharge pipe range time afterflow, temperature raises, and leads to lightning protection
In module, associated materials catch fire.
Therefore, how to prevent lightning-protection module from catching fire because overheated becomes this area technical problem urgently to be resolved hurrily.
Utility model content
For the deficiencies in the prior art, this utility model provides one kind no continued flow switch type lightning-protection module, solves biography
For example the tolerance of T1 class lightning-protected product (10/350uS) energy is limited, response time is slow, residual voltage is high, intermittent current ability for system lightning-protected product
The traditional shortcomings such as weak and cost height.Efficiently solve the through-flow greatly lightning-protected product of traditional T2 class simultaneously and get used to the pressure-sensitive of employing
There is the appearance deterioration of leakage current on-line operation and thread off in the drawbacks of multi-disc raising in parallel through-current capability is brought, such as varistor MOV
The bad phenomenon such as on fire.
Solve above-mentioned technical problem, the technical solution adopted in the utility model is：
One kind no continued flow switch type lightning-protection module, including first support assembly 1, gas-discharge tube 2, no afterflow lightning protection component
3 and second support assembly 4；First support assembly 1, gas-discharge tube 2 and no afterflow lightning protection component 3 pass sequentially through connection and tether
Connect, no afterflow lightning protection component 3 bottom is connected with second support assembly 4.
Further, described no afterflow lightning protection component 3 includes steel housing 7, lid 9, contact rod 5 and cut-off 6, contact rod
5 are located at center in steel housing 7, and lid 9 is stretched out in upper end, and cut-off 6 is horizontally set on the interposition in steel housing 7
Put, be separated into upper and lower two spaces by inside steel housing 7, upper space is filled with the first dielectric substance 11, lower space
It is filled with the second dielectric substance 12.
Further, the bottom of steel housing 7 arranges the first insulating barrier 8.
Further, the lower section of lid 9 arranges the second insulating barrier 10.
Further, the resistance value of the first dielectric substance 11 is 35-40 Ω, and the resistance value of the second dielectric substance 12 is
25-30Ω.
Compared with existing lightning-protection module technology, no continued flow switch type lightning-protection module of the present utility model employs Novel lightning-proof
Assembly replaces traditional varistor, enormously simplify structure and the volume of lightning-protection module, fills stepped in lightning protection component
High resistance dielectric substance, maximum continuous running voltage up to 275V, this lightning-protection module can bear 2.5kV restriction voltage and not
There is flashover and puncture, no afterflow produces, and the lightning-protection module leading to because lightning-protection module is overheated can be avoided to catch fire.
