Description
Technical field
The present invention relates to the device that a kind of high-pressure side is got can provide the low-pressure end device power supply (DPS).
Background technology
Ultra-high-tension power transmission line needs various monitoring equipments to carry out the lead status monitoring; The normal mounting place of monitoring equipment is positioned on the iron tower of transmission line mostly; Iron tower does not have low-voltage power supply, and power source design therefore commonly used is to use storage battery to add the method for solar recharging.Problems such as this power source design exists the battery life weak point, receives weather influence big, and reliability is low; Often because overcast and rainy oversize, ice and snow covers or the conversion in season causes problems such as light intensity variation, the solar panels cisco unity malfunction causes running down of battery; System can not normally move, even condition takes a turn for the better, also because of phenomenon takes place to put battery irreversible lesion takes place; Life capability sharply reduces, and system can not normally move.Therefore design a kind of reliable monitoring system power supply the safe operation of transmission line monitoring equipment is seemed very important.
For satisfying the monitoring system power requirement, we are employed in high-pressure side and utilize high pressure to get to obtain electric energy, drive laser by equipment; Send energy laser; Laser passes to low-pressure end through the optical fiber insulator passage, converts laser to electric energy at low-pressure end, supplies with the power source design of monitoring equipment.Still the power source design that does not have at present this type of application.
It can technology be that a kind of employing is got and can be hung on the high-voltage conducting wires by coil that high pressure is got; Utilize the technology of lead surrounding magnetic field variation sensing power taking; It only receives the influence of current in wire, as long as lead has electric current to pass through, just can obtain induction electric energy; Do not receive the influence of external conditions such as weather, be fit to very much the power demands of transmission of electricity monitoring equipment.
High pressure is got the electric energy that can obtain at high-pressure side, and therefore monitoring equipment needs to adopt electric light/opto-electronic conversion mode that electric energy is passed to low-pressure end mostly at low-pressure end.This mode has guaranteed reliably insulation between the high-low pressure end, has realized the transmission of electric energy again.
The electric light switch technology promptly at high-pressure side with the electric energy drive laser that obtains, produce power laser.
Photoelectric conversion technique promptly converts the energy laser radiation to electric energy at low-pressure end to electrooptical device, can supply monitoring equipment to use.This electrooptical device is the photo-detector that aims at the high photoelectric efficiency of energy laser converting electrical energy design.
The transmission of laser between the two needs the optical-fibre channel insulator that laser transmission passage and high pressure creep distance are provided.
