Description

The thunder resisting equipment intelligent monitor system

Technical field

The utility model relates to the electronic electric equipment field, refers more particularly to a kind of terminal of thunder resisting equipment intellectual monitoring.

Background technology

Lightning hazards has caused countless economic losses and casualties as one of the world's ten the Nature disasters to the mankind, and the particularly development of hyundai electronics information and new energy technology, the harm of thunder and lightning become more extensively and in-depth.The frequent birth that promotes the lightning protection industry of thunder disaster, up to the present, world's thunder and lightning industry size is very huge, the lightning protection product applications is constantly expansion also, has been extended to a plurality of modernized fields such as military project space flight, IT application in enterprises system, new forms of energy, electric railway from initial building, power domain.

Good lightning protection effect, except the superior lightning protection product of needs, the correct and detection regularly of the survey and design of lightning protection engineering, construction and installation safeguards it also is very important.If go wrong in any one link of survey and design, construction and installation, even best lightning protection product is not realized desirable lightning protection effect yet.People have proposed lightning protection " three is excellent " theory at this point, i.e. " product is excellent, design proposal is excellent, install excellent " has only strictness to follow " three is excellent " principle, just can reach optimal lightning protection effect.

Continuous increase along with the time, various variation can appear in lightning protection and earthed system, inefficacy and stake resistance as lightning protection increase gradually, can make existing lightning-protection system depart from needs of expected design, so regularly effectively lightning-protection system is carried out the emphasis that reliable detection is lightning protection work.

380/220V distribution system lightning arrester is the important electrical equipment that protection distribution line and electric system consumer are avoided overvoltage injury, and its reliability of operation will directly influence the safety of distribution line system safety itself and electric system.In the past, by manually regularly or irregularly patrolling and examining to carry out, can't in time find the lightning arrester fault to the monitoring of lightning arrester, more be difficult to find to produce the big defective of fault.Degradation lightning arrester faster might just break down in 1 polling period fully: lost efficacy, burn even blast, the repeatedly similar accident of Fa Shenging in recent years, not only brought enormous economic loss, and serious threat is to the safe operation of distribution line.The distribution lightning arrester is implemented the long-distance intelligent on-line monitoring, can find early and fix a breakdown on the one hand, avoid causing because of the lightning arrester fault damage of distribution line and consumer, perfected the safe operation early warning system of distribution line lightning arrester; On the other hand, though low voltage surge arrester generally has the inefficacy state output signal, this signal is make-and-break signal, can't directly realize remote transmission.If the failure condition to lightning arrester can be realized data remote, thereby just can detect lightning arrester inefficacy, damage etc. effectively in time.Therefore, application lightning arrester long-distance intelligent on-line monitoring system is significant.
