Operation principle of the present utility model is：This utility model is related to a kind of electric supply installation, from overhead transmission line insulation
Ground line extraction electric energy, for on-line monitoring device for transmission line and aviation obstruction beacon reliable and stable working power is provided.Its is main
Operation principle is as follows：
1st, transmission line of alternation current can produce electromagnetic induction, as shown in Figure 4 when electric energy transmission is carried out.Due to two ground wires
Between there is phase contrast, therefore, circulation between line can be formed between two ground wires.Circulation is in transmission line of electricity operation between this partial line
The normal loss of generation.Such as this partition losses are carried out solving by extraction utilization with low-capacity electric equipment on transmission line of electricity
Powerup issue.
2nd, for possessing the exchange overhead transmission line of double earth wire, in 2～8kM insulating segments, common ground wire is carried out circuit
Insulation processing, OPGW is not changed.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 directly connected to steel tower.Such as Fig. 3
It is 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, it is subjected to 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% or so lightning current.Remaining lightning current is moved back flowing through
During coupling device, it will puncture lightning protection for power supply A, remaining lightning current of releasing, such as lightning current is excessive, then by lightning protection for power supply B
Carry out remaining whole lightning currents to release.Now, lightning current is all grounded by steel tower and is released, without flowing into this device
AC-DC conversion sections make burning for cost apparatus and load.The part design is as shown in Figure 5.

Running status.This device passively monitors product running status by 2G modes.This device fortune can be inquired about by GSM message form
Row state.Consider to reduce user's operating cost simultaneously, this device can just send warning information only in operation irregularity.
5th, this device adopts modularized design, and outside power supply, each several part detection signal Jing is adopted monitoring means independent operating
Monitoring signals processing unit is transferred to after sample, isolation, monitoring signals processing unit can be single by GSM transmission after computed in software
Unit carries out remote data transmission and RS485 area communication units and carries 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, due to this device energy input from transmission line of electricity run when sensing, induced voltage and transmission line of electricity
Conveying electric current is proportional, and transmission line of electricity conveying current transformation is larger, therefore the input voltage Parameters variation of this device is big,
And stable output voltage is maintained, this device takes PWM control methods to carry out circuit design.The AC-DC designs of this device are former
Reason is first alternating current to be carried out into primary rectifier filtering to be converted into unidirectional current, is then converted to disposable 12V through DC-DC straight
Stream.Then secondary rectification, filtering are carried out, Eliminate highter harmonic and ripple affect, and obtain stable 12V direct current outputs.Through right
PWM controller is fed back to after output signal sampling, dynamic regulation output voltage is realized, so as to reduce change of the output voltage with load
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 for collecting is converted to TTL signal after single-chip microcomputer computing, and Jing RS485 blocks carry out local data transfer,
May also pass through gsm module simultaneously carries out long-range note data transmission.Due to the equal independent design of each module, occur in monitoring means
The work of unit module is had no effect on during failure, the fault rate of this device can be substantially reduced.
8th, it is the safety for ensureing power system because this device can adopt SMS message transmission data, copies information leakage.This dress
Put and take password to read parametric form.Before short-message instruction is received must by password authentification can returned data instruction, it is to avoid
Information leakage.
