Description
One technical field
The invention belongs to transmission and distribution networkses intellectualized technology field in intelligent grid, specifically a kind of transmission and distribution networkses are automatic
Lightning strike information arrester, it can make line related realize operation thunderbolt automatic alarm with equipment, realize transmission and distribution networkses arrester
Automatic monitoring lightning strike information, automatic identification thunderbolt state and automatic alarm are sent.
Two background technologies
Arrester is that the high-voltage electrical apparatus such as electric line and insulator part of appliance absorbs the electricity that was struck by lightning when being struck by lightning
Pressure, to protect the equipment for power transmission and distribution that these link together from the overvoltage.
One of key of transmission and distribution networkses safety is in arrester, and it, which is played, effectively absorbs lightning overvoltage protection transmission and distribution line
Road and the effect of high-tension apparatus；But so far, arrester is that itself absorbs overvoltage there, and thunder can not be provided automatically
Hit information；People often still further add the inspection to lightning strike information to grasp transmission and distribution networkses and arrester by thunderbolt situation
Survey, arrester is struck by lightning after condition detection, also to solve the problems, such as power issue, telecommunication of this detection etc..
Circuit or insulator where being found automatically if a kind of arrester for transmission and distribution networkses and itself by thunder
Hit, at once clear and definite thunderbolt time and by thunderbolt position, and outside switch fault report lightning strike information in time, then it can substantially improve network thunder
Situation is hit, mitigates the maintenance workload of circuit operating maintenance personnel significantly, the power supply reliability and voltage for greatly improving power network are closed
Lattice rate.
Three content of the invention
It is an object of the present invention to provide the arrester of lightning strike information can be reported during a kind of transmission and distribution networkses on-line operation automatically, make
The equipment state after thunder-strike current size, thunderbolt time, thunderbolt can be found after thunderbolt in time, and can be in time to management backstage
Report lightning strike information；In arrester failure because of thunderbolt, moreover it is possible to give manager's promptly and accurately fault message, promote and safeguard in time
High pressure transmission and distribution networkses operation safety, is preferably minimized network failure loss.
The present invention makes arrester monitor the size of flowed through electric current automatically, and these electric currents of automatic decision are whether more than setting
Threshold value, provides alarm when thunder-strike current exceedes threshold value automatically, and automatic distally manager sends out warning message, makes transmission ＆ distribution
Electric network manager can obtain lightning strike information in time, lightning fault be found, so as to promptly and accurately handle lightning strike accident with safety
Power transmission.
The automatic lightning strike information arrester of this transmission and distribution networkses invented, including lightning arrester body 1, arrester information portion
Divide 2；Wherein arrester message part 2 obtains circuit 22, current sense by information primary processor 20, communication processor 21, power supply
Device 31, current processor 32 are constituted.
The automatic lightning strike information arrester of described transmission and distribution networkses is characterized in that takes one kind in current processor 32
Current limit auto discovery mechanism, the mechanism sets a kind of current threshold as needed, and selection current sensor 31 makes acquisition electricity
Size information is flowed, when finding that electric current reaches threshold value, starts transmitting-receiving communication process 21 and sends and realize that excessively stream is alarmed, current reduction
The report of electric current safety is provided when returning below threshold value.
The automatic lightning strike information arrester of described transmission and distribution networkses, wherein electronic circuit outside need not provide power supply, adopt
Arrester itself is taken to obtain power supply mechanism from thunder and lightning, the mechanism makes to obtain sufficient electric energy in heavy current moment, satisfactory to realize electricity
Sub-circuit information processing and to backstage communication alert.
The feature of communication processor 21 is in the automatic lightning strike information arrester of described transmission and distribution networkses：By automatic lightning strike information
The address information coding that arrester is installed enters to be sent in communication information frame to backstage, and it is online that the address specifies arrester institute
Also include this transmission current data in phase bit number in ABC three-phases where road numbering, shaft tower numbering, arrester, information frame
Classification size；This address causes manager to will be apparent that by thunderbolt arrester position, is convenient to timely overhaul plan.
4th, illustrate
Fig. 1 is the automatic lightning strike information arrester composition structure chart of transmission and distribution networkses, including：It is lightning arrester body 1, lightning-arrest
Device message part 2；
Fig. 2 shows that information treatment part is grouped into structure in the automatic lightning strike information arrester, and core is information primary processor
20th, communication processor 21, power supply obtain circuit 22, arrester current sensor 31, current processor 32.
5th, embodiment
The present invention is pointed out in Fig. 1 --- the automatic lightning strike information arrester of transmission and distribution networkses is overall, wherein the major part of body 1
It is metal oxide arrester；Arrester message part 2 depends on lightning arrester body 1, and organic composition is in the lower section of body.
Fig. 2 illustrates the composition and connected mode of message part 2 in automatic lightning strike information arrester of the invention；Wherein electric current
The current signal that arrester where the collection of sensor 31 flows through, sends into current processor 32, and excessively stream or the electric current close to threshold value are believed
Breath is sent to arrester information primary processor 20, through judging that need electric current then to start communication processor 21 when alarming manages to power transmission and distribution
Center background is sent.
Communication processor 21 in the automatic lightning strike information arrester, the address information of this arrester is encoded to communication by it
Sent in information frame, ABC tri- where circuit number, shaft tower numbering, arrester where the address indicates the arrester for sending information
Also include the classification of this transmission current data in phase bit number in phase, information frame；This address causes manager will be apparent that
This time lightning fault position, is convenient to timely overhaul plan.
Transmission and distribution networkses thunder-strike current situation can most reflect network thunderbolt situation, automatic lightning strike information arrester aforesaid way
Implementation intactly report where the operation conditions of circuit, lightning fault situation and by thunderbolt position, can effectively facilitate to thunder
The processing of failure Quick overhaul is hit, promotes line security stable operation, very well enhancing transmission and distribution networkses power supply reliability, raising power network
Rate of qualified voltage.
