The operation principle of the present invention is: the present invention relates to a kind of electric supply installation, extracts from overhead transmission line Ground wire with insulation ocver
Electric energy, is on-line monitoring device for transmission line and aviation obstruction beacon provides reliable and stable working power.Its main operational principle
As follows:
1st, transmission line of alternation current, when carrying out electric energy transmission, can produce electromagnetic induction, as shown in Figure 4.Between two ground wires
There is phase contrast, therefore, circulation between line can be formed between two ground wires.Between this partial line, circulation is to produce during transmission line of electricity runs
Normal loss.As this partition losses is carried out with extract the power supply that utilization can solve the low-capacity electric equipment on transmission line of electricity
Problem.
2nd, it is directed to the exchange overhead transmission line having double earth wire, in 2～8km insulating segment, common ground wire is carried out circuit
Insulation processing, opgw does not change.Supply unit is located on a base steel tower, and an input is electrically connected with Ground wire with insulation ocver
Connect, another input is connected on steel tower.The other end of insulating segment, common ground wire and opgw are all directly connected to steel tower.As Fig. 3
Shown.Faradic principle on Ground wire with insulation ocver is as shown in Figure 4.
3rd, because this electricity getting device is directly electrically connected with Ground wire with insulation ocver, suffer from lightning strike probability larger.Must carry out
Sufficiently lightning protection considers.This device employs decoupling coil, decoupler and two-stage lightning protection for power supply modular design.When thunder and lightning hits
During Ground wire with insulation ocver, the input voltage rapid increase of this device, in the lightning leader stage, the decoupling coil of this device can apply reversely
Electromotive force, the discharging gap of ground insulator is punctured, release 70% about lightning current.Remaining lightning current moves back flowing through
During coupling device, it will puncture lightning protection for power supply a, remaining lightning current of releasing, as excessive in lightning current, then pass through lightning protection for power supply b
Carry out remaining whole lightning current to release.Now, lightning current is all released by steel tower ground connection, without flowing into this device
Ac-dc conversion section makes burning of cost apparatus and load.The design of this part is as shown in Figure 5.
4th, mostly run on, in view of this device, the region that personnel are difficult to reach, staff needs remotely to monitor this device
Running status.This device passively monitors product running status by 2g mode.This device fortune can be inquired about by gsm note form
Row state.Simultaneously take account of reduction user's operating cost, this device just can send warning information only in operation irregularity.
5th, this device adopts modularized design, and, outside power supply, each several part detection signal is through adopting for monitoring means independent operating
It is transferred to monitoring signals processing unit, monitoring signals processing unit can transmit single after computed in software by gsm after sample, isolation
Unit carries out remote data transmission and rs485 area communication units carry out local data transfer.Because monitoring means do not enter to power supply
Any reverse data transmission of row, therefore when monitoring means break down, power module remains to maintain normal output, keeps equipment
Power supply.
6th, because the energy input of this device derives from sensing when transmission line of electricity runs, induced voltage and transmission line of electricity
Conveying electric current is proportional, and transmission line of electricity conveying current transformation is larger, and the therefore input voltage Parameters variation of this device is big,
And stable output voltage will be maintained, this device takes pwm control methods to carry out circuit design.The ac-dc design of this device is former
Reason is first alternating current to be carried out primary rectifier filtering to be converted into unidirectional current, and being then passed through dc-dc, to be converted to disposable 12v straight
Stream.Then carry out secondary rectification, filtering, Eliminate highter harmonic and ripple impact, obtain stable 12v direct current output.Through right
Feed back to pwm controller after output signal sampling, realize dynamic regulation output voltage, thus reducing the change with load for the output voltage
Change and fluctuate.Theory diagram is as shown in Figure 1.
7th, this device is provided with the monitoring means of power supply operational factor, outside power supply mainboard.Monitoring means will be adopted
The plant running parameter collecting is converted to ttl signal after single-chip microcomputer computing, carries out local data transfer through rs485 block,
May also pass through gsm module simultaneously and carry out long-range note data transmission.Due to the equal independent design of each module, occur in monitoring means
Have no effect on the work of unit module during fault, the fault rate of this device can be substantially reduced.
8th, because this device can adopt SMS message transmission data, for ensureing the safety of power system, imitated information leakage.This dress
Put and take password to read parametric form.Can returned data must be instructed by password authentification before accepting short-message instruction, it is to avoid
Information leakage.
