Description
Technical field
The invention belongs to lightning protection field, the Intelligent Measurement of building lightning protection system is mainly used in.
Background technology
Apparatus and method there is no to change the weather phenomenon of nature to prevent the generation of thunder and lightning so far, thunder and lightning, which is hit, to be built
Build thing or building nearby to people, building in itself, its internal objects, equipment and service facility be all dangerous, therefore must
It must consider to take lightning protection measures.Complete lightning protection measures include direct lightning strike protection and Lightning Electromagnetic Pulse protection, direct lightning strike protection
Measure includes installation arrester, installation downlead, lays earthing or grounding means, sets spacing distance, equipotential link, thunder and lightning electromagnetism arteries and veins
Rushing safeguard procedures includes installation Surge Protector（SPD）, space and cable shielding, reasonable line arrangement, equipotential link etc..Synthesis is examined
Consider above synthetical prevention and cont rol, the specific device and equipment that need to be installed have arrester, earthing or grounding means and SPD, and other are one
Kind measure.
Arrester is a kind of metal parts for being used to connect sudden strain of a muscle, and on building roof, the lightning received will be by drawing
Offline grounded device is released into the earth.Arrester connects the situation of sudden strain of a muscle, can reflect local thunderbolt situation, such data can
Designer is helped to design more applicable lightning protection measures.Therefore direct lightning strike detection is to taking appropriate lightning protection measures to have very much side
Help.
Safe and reliable earthed system, safe operation to systems such as information system, electric power and prevents accident from having
It is of great significance, the quality of earthed system is directly connected to electrical equipment normal work and the safety of the person.But due to
Earthed system is affected by various factors larger, such as couple corrosion, mechanical trauma, grounding body environmental change, may cause to be grounded
Resistance change is larger.If grounding resistance is excessive, potential safety hazard is brought to equipment and personal safety, equipment normal operation.
Therefore it is very necessary earthed system to be measured in real time.
SPD is thunder and lightning and the Primary Component of overvoltage protection system, but it is a kind of " sacrificing oneself, protect others "
Device, when SPD is by lightning surge electric current or long-term use, necessarily there are the states such as aging, deterioration and damage, its state it is good
It is bad then directly affect its protection effect.But the characteristics of purposes and operation principle due to SPD itself, SPD aging, deterioration shape
State detection is always a global problem, so either domestic or external SPD can only carry out Failure Alarm.This is just produced
A problem is given birth to, the problem for only solving SPD various state-detections, the use that could veritably improve user equipment is pacified
Entirely.Current SPD can only rely on the artificial failure to site inspection equipment to show, be tieed up so as to judge whether equipment needs to change
Shield, but for as units such as electric power, communication, railway, civil aviatons, it needs the equipment of lightning surge and overvoltage protection to have will
The characteristics of high, distribution is wide, website is more, position is inclined is asked, to accomplish the scene progress for allowing attendant to reach every Surge Protector
Check, very difficult, cost is high.This just generates a problem again, only realizes the intelligence system of collection medium-long range monitoring,
The each SPD in scene working condition can timely be known, so as to greatly reduce maintained equipment maintenance cost.
If three above Resolving probiems are formed a novel intelligent lightning-protection system, then will greatly carry simultaneously
The safety coefficient of high lightning surge and overvoltage protection system, can be the property loss caused by country's reduction Lightning Disaster, together
When for all trades and professions reduce maintenance cost, there are huge social and economic benefits.
The content of the invention
In order to effectively solve problem above of the prior art, the present invention proposes a kind of Novel lightning-proof detecting system, integrates
Building arrester, earthing or grounding means and SPD are managed, forms comprehensive intelligent lightning protecting detecting system.
The technical scheme is that a kind of Novel lightning-proof detecting system, including intelligent direct lightning strike detector, intelligent SPD,
Smart grounding resistance measuring instrument, data collection station, monitoring host computer, 485 buses, netting twine.The intelligent direct lightning strike detector by
Sensing box and signal acquisition case composition, sensing box are connected with signal acquisition case；The signal acquisition case, smart grounding resistance measurement
Instrument, intelligent SPD are connected by 485 buses with data collection station, then are sent to monitoring host computer by netting twine；The netting twine is also
It can be replaced by optical fiber, CAN, corresponding signal conversion equipment need to be increased.
Intelligent direct lightning strike detector of the present invention can be detected by sensing box flows through arrester lightning current, passes through data wire
Signal acquisition case is transmitted information to, and analyzes and calculates its size, waveform, duration, peak value, frequency and energy, then is passed through
485 buses or the mode being wirelessly transferred, these data and figure are sent to monitoring host computer or user mobile phone, so as to be user
Data are accumulated, it is convenient to understand local thunderbolt situation.
Smart grounding resistance measuring instrument of the present invention is installed in the loop of the existing earthing or grounding means of building, be can detect back
Road grounding resistance, and by 485 bus transfers to monitoring host computer, so as to allow user to understand the change of earth mat resistance in real time,
Once exceeding danger threshold, drop resistance can be tried in time.
Intelligent SPD of the present invention is different from common SPD, detection module built in the intelligent SPD, can detect each lightning protection
The working condition of lightning protection component in module, and monitoring host computer is sent to by 485 buses, so as to realize the reality to each SPD
When monitor, understand SPD deterioration conditions, predict its service life in advance, the life-span exceed early warning value before safeguarded or changed,
Ensure the continuity of lightning surge and overvoltage protection, greatly save maintenance cost.
Each lightning protection device is carried out unified monitoring management by Novel lightning-proof monitoring system of the present invention, only needs a monitoring
Main frame, you can grasp the working condition of whole lightning-protection system, for the reliable lightning protection of building, personnel effectively safeguard, efficiently management carries
For powerful guarantee.
