Description
Technical field
It the utility model is related to and be based on high-capacity and high-speed data storage transmission line of electricity distribution windburn monitoring system, belong to defeated
The monitoring technology field of line fault hidden danger.
Background technology
The English of OPGW is Optical Fiber Composite Overhead Ground Wire,
It is abbreviated as OPGW, commonly referred to as OPGW optical cables.This structure type has ground wire and the dual-use function that communicates concurrently, is maked somebody a mere figurehead in high voltage power transmission
Generally used in circuit.OPGW as communications optical cable have reliability is high, anti-natural calamity ability is strong, be not easy by artificial destruction,
The advantages such as service life is long, operation and maintenance cost is low.But in the OPGW design service life time limit, once ground wire function
Or optical fiber communication function is lost, and not only terminates service life, it is often more important that can cause huge loss of outage and influence, also
The safe and stable operation of entail dangers to power network.
Because OPGW is chronically under open field, it is easy to by natural conditions such as wind, rain, ice and snow, thunders and lightnings
With the influence of other external conditions, various accidents easily occur.Wherein, the accident that wind shake triggers is most.Under wind action, lead
The line moment is in vibrational state, and according to frequency and the difference of amplitude, wire aeolian vibration generation is the most frequent, therefore, finds out phase
The vibration protection answered has caused the most attention of domestic and international scientific worker.
Destruction of the aeolian vibration to transmission line of electricity has certain disguise, because aeolian vibration feature is the small amplitude of low frequency
Vibration, caused this vibration, is generally with the naked eye not easily seen on high voltage overhead lines, it unlike electric wire wave when
It is directly perceived like that.The circuit fatigue accident such as stranded caused by aeolian vibration is, it is necessary to have an accumulated time and process.It is generally found that
Harm is after producing the stranded or antivibrator of fatigue and damaging and come off, and at this moment circuit harm is heavier.And lot of examples and examination
Test and show, it is tired stranded that aeolian vibration produces OPGW, sometimes since OPGW internal layer, can't find from wire appearance.
Aeolian vibration monitoring method traditional at present is that important point installation aeolian vibration prison is chosen in OPGW circuits
Survey device to be monitored, each point transmits data to user terminal using GPRS communication modes, in the wild adverse weather condition
Communicated existing for lower, monitoring surface is narrow and stability problem.
The monitoring system of distributed power transmission line windburn at present carries out data storage using industrial computer, and data storage capacity has
Limit, typically within 1T bytes, due to being limited by disk size, may be only configured to General Oscillation frequency range, low resolution,
The on-line monitoring of relatively short distance obtains longer time data memory to save disk space.

The purpose of this utility model is to be based on high-capacity and high-speed data storage distributed power transmission line windburn monitoring system, is led to
Cross industrial computer to be connected with storage array, expand the data storage capacity of industrial computer significantly, can not be limited, entered by disk size
Row prolonged broader vibration frequency range, higher resolution ratio and the more monitoring of long transmission line distance, obtain systematic function
Improve.
The technical scheme of the present apparatus is as follows：Monitored based on the windburn of high-capacity and high-speed data storage distributed power transmission line and be
System, including transmission line of electricity OPGW optical cables, SAN storage arrays, phase sensitive optical time domain reflectometer and industrial computer, it is characterised in that：
OPGW optical cables are arranged on transmission overhead line tower bar top, and a power transmission line OPGW core free time optical fiber and phase sensitive optical time domain is anti-
Penetrate instrument connection；Phase sensitive optical time domain reflectometer is connected with industrial computer；Industrial computer connects with SAN storage arrays.
Described SAN storage arrays, phase sensitive optical time domain reflectometer, industrial computer are installed in the rack of transformer station's computer room
It is interior.
Described phase sensitive optical time domain reflectometer is connected as phase sensitive optical time domain reflectometer and industrial computer with industrial computer
Connected by netting twine with USB line.
Described industrial computer is connected as industrial computer with SAN storage arrays and connected with SAN storage arrays by netting twine.
The utility model uses the storage array based on SAN storage frameworks, is connected by industrial computer with storage array, significantly
The data storage capacity of industrial computer is expanded, can not be limited by disk size, carries out prolonged broader vibration frequency model
Enclose, higher resolution ratio and the more monitoring of long transmission line distance, systematic function is improved.
