Description
Technical field
The utility model relates to the outdoor protective device of electronic product field, at length says it is ten kilovolt-amperes of lightning-protection modules of a kind of external Millisecond.
Background technology
As everyone knows: present outdoor electronic product often runs in application process by thunderbolt and damages phenomenon, and What is more because thunderbolt causes electronic product to rise fights and cause serious fire takes place on every side, loses more serious.Traditional electronic product lightning protection measures is between live wire and zero line and a piezo-resistance; What have directly is to be distributed in the fuse front to piezo-resistance, and when thunderbolt took place, piezo-resistance was generated heat until burning; Thereby the electronic device around causing is and then burning also, and more serious thing takes place; What have directly is distributed in piezo-resistance fuse at the back, and thunder-strike phenomenon takes place a little, will cause blown fuse, thereby also cause electronic product owing to there not being electricity to lose all functions.
Summary of the invention
It is not enough that the purpose of the utility model just is to overcome existing outdoor use electronic product lightning protection, provides a kind of external Millisecond ten kilovolt-amperes of lightning-protection modules, easy installation and removal; Moisture-proof anticorrosive is effective, and reaction speed is fast, and the lightning protection capacity is big; Can not burn, and cost performance is high.
The utility model adopts following technical solution: ten kilovolt-amperes of lightning-protection modules of a kind of external Millisecond; It is characterized in that: form by fuse F1, fuse F2, piezo-resistance RV1, piezo-resistance RV2, piezo-resistance RV3, discharge tube FDG1, discharge tube FDG2; The pin of fuse F1 links to each other with zero-power line N; The fuse F1 other end links to each other with the end of piezo-resistance RV2; The other end of piezo-resistance RV2 links to each other with the end of discharge tube FDG1, and the other end of discharge tube FDG1 links to each other with the power safety ground wire; The pin of fuse F2 links to each other with power firestreak L, and the other end of fuse F2 links to each other with the end of piezo-resistance RV3, and the other end of piezo-resistance RV3 links to each other with the end of discharge tube FDG2, and the other end of discharge tube FDG2 links to each other with the power safety ground wire; The pin of piezo-resistance RV1 links to each other with the common port of piezo-resistance RV2 with fuse F1, and the other end of piezo-resistance RV1 links to each other with the common port of piezo-resistance RV3 with fuse F2.
The beneficial effect of the utility model is,, is connected in parallel on by power supply input place of protection electrical equipment also several lightning-protection module how in the apparent in view area of thunderbolt through an external lightning-protection module.This module installing/dismounting is all more convenient, is quick on the draw during thunderbolt, and control board is irritated the fluid sealant sealing, good water-proof effect, and leakproof, safe and reliable, and lightning protection effect is good, and cost performance is high, but generalization is strong.
