The features such as.In order to reduce overhead distribution failure caused by the external causes such as trees, birds, accumulated snow, power supply reliability is improved,
Developed countries have gradually adopted suspended insulated guide wire from later period the 1960s, in Japan, overhead distribution base
This realization insulating.China implements insulating to urban aerial power distribution network since the eighties is also and pilot is transformed, from the nineties
Paces are accelerated, if 5, Beijing urban and suburban areas power supply bureau 10kV overhead transmission line is always about 3458km, will be had been carried out to the end of the year 1998
The route of insulation is about 2436km, and insulation rate is up to 70.4%.Japan concludes that insulated conductor meets with through research in the early 1990s
Broken string is easily caused by lightning stroke.Such as only Beijing is in 1 year 2005, the 10kV aerial insulated wire of power supply bureau's administration
Lightning-caused breaking occurs altogether for road up to 38 times.In fact, the system of lightning-caused breaking and insulator breakdown accident occurs for insulated circuit in recent years
Count number is on the rise, and is steeply risen as insulated conductor line length increases, it has also become seriously threatens distribution
The main contributor of cable road safe operation.According to statistics, external to be sent out about running insulated circuit during 1999 to 2000
Raw lightning stroke and insulator breakdown accident quantity account for the 74.9% of its total number of accident amount, the direct economy due to caused by lightning-caused breaking
Up to more than 1.2 hundred million dollars of loss；Domestic insulated circuit lightning-caused breaking accident situation allows of no optimist, according to incompletely statistics, cut-off
In the end of the year 2000, it is disconnected that insulated circuit lightning stroke occurs altogether for the ground such as domestic some cities such as Shanghai, Beijing, Wuhan, Xiamen, Ezhou, Shandong
Line accident about 395, and cause a lot of personal injuries and huge property economic loss.It is extensive especially with China in recent years
Upgrading urban and rural power grids, the more and more urban power distribution network in the whole nation largely use suspended insulated guide wire route.Therefore, how properly
Lightning-caused breaking, string pendulum is solved to cause clearance distance to become larger and failure protect to break down the problems such as positioning, with ensure it is aerial absolutely
The safe operation of edge power distribution network has become a major issue very in the urgent need to address in national distribution network system.
In view of the above problems, exploitation, which is suitable for distribution line overhead insulated conductor lightning protection, hits protection requirement, realize to distribution
The effective protection of insulated conductor direct lightning strike or lightning induced voltage, Exocarpium Citri Rubrum color bands can effectively indicate the fault bit of protective device
It sets.There is provided one kind for distribution line can be filled with the intelligent overvoltage protection of effective protection, status data transfers, position mark
It sets, effectively improves the safe and stable operation of distribution line, the service life of lifting protection device avoids that broken string, insulator occurs
Flashover or breakdown and cause large-area power-cuts and cause great personal injury accident and economic loss.
Summary of the invention

Shield device is connect with a monitor terminal respectively.
The intelligent lightning protecting over-voltage protector sends out collected number of lightning strokes, installation site information, status information
It send to remote monitoring terminal and is uploaded to central server, when data are more than established standards value, linkage remote alarming device will
Automatic to issue alarm signal, when data are lower than established standards value, remote monitoring terminal will collect the data automatically and will count automatically
According to central server is uploaded to, central server carries out intellectual analysis to historical data, and automatically generates Risk Assessment Report.
The remote alarming device further includes sound broadcasting device, sound broadcasting device and remote monitoring center server
Connection prompts staff to handle for carrying out audio alert casting in superscalar data.
The intelligent lightning protecting over-voltage protector is by the way that " discharging gap 6 is connected with route 5；Discharging gap 6 passes through current limliting
Element 7 is connected with state instruction GPRS communication module 8.
The intelligent lightning protecting over-voltage protector is wirelessly connect with the monitor terminal, using 4G network into
The transmission of row data.
The intelligent lightning protecting over-voltage protector is connected by discharging gap 6 with distribution line；Discharging gap passes through limit
Fluid element is connected with state instruction GPRS communication module 8.
The central server obtains data after staff starts work, from monitor terminal, alarms if any data,
