Detailed description of the invention
Below in conjunction with the accompanying drawings the detailed description of the invention of the present invention is elaborated.
As it is shown in figure 1, the present invention includes housing, in described housing, it is provided with voltage transformer, transducer, lithium
Battery, energy-storage travelling wave tube and detecting element, winding two ends of described voltage transformer connect high line line respectively
Biphase on road, Secondary Winding one end ground connection of described voltage transformer, described transducer include fixed port,
First conversion port and the second conversion port, one end of the Secondary Winding of described voltage transformer connects fixing end
Mouth and the other end connect the first conversion port, and one end of described lithium battery connects fixed port and the other end connects
Second conversion port, is provided with Converting terminal and magnetic core in described chopper, described Converting terminal includes fixing end
And movable end, one end of described detecting element connects fixed port and the other end connects movable end, described energy storage
Element is in parallel with detecting element, and described fixing end is connected with fixed port, and described movable end is at the first end of convert
Switching between mouth and the second conversion port, the two ends of described magnetic core connect Secondary Winding and the magnetic core of voltage transformer
Making movable end overlap the first conversion port when charged, described movable end is provided with back-moving spring, described reset
Spring makes movable end redirect overlap joint the second conversion port when magnetic core dead electricity.The lateral surface of described housing is provided with too
Sun can photovoltaic panel, the outfan of described solar energy photovoltaic panel is connected with lithium battery, lithium battery by solar powered,
Add the flying power of detecting element.Described energy-storage travelling wave tube is super capacitor, passes through voltage transformer secondary
Winding charges, and when rainy weather causes electric quantity of lithium battery deficiency, super capacitor still is able to enter detecting element
The long-time continuation of the journey of row.
The operation principle of the present invention is:
Owing to magnetic core is connected with secondary windings of PT, under secondary windings of PT electriferous state,
Magnetic core, with electromagnetic force, makes the movable end of Converting terminal overlap the first conversion port, and now, detecting element is even
The two ends of logical secondary windings of PT, detecting element is powered by the direct power taking of high-tension line, power supply
More reliable and more stable, secondary windings of PT can be charged energy storage to energy-storage travelling wave tube simultaneously；
When high-tension line runs into fault power-off, secondary windings of PT dead electricity, magnetic core loses electromagnetic force,
Back-moving spring is multiple to the automatic switchover of the second conversion port by the first conversion port by the movable end of Converting terminal
Position, so that detecting element circuit communication lithium battery, now, detecting element is by lithium battery and energy-storage travelling wave tube structure
The stand-by power supply become is powered, and has ensured the constantly electricity work of on-line monitoring terminal, has examined at high-voltage line fault
After having repaiied Power resumption, in like manner, continuation is powered by detecting element by the direct power taking of high-tension line.
Above preferred embodiment of the present invention is described, but is not to be construed as the restriction to claim.
The present invention is not only limited to above example, and its concrete structure allows to change, and those skilled in the art are permissible
It is variously modified according to the present invention and deforms, without departing from the spirit of the present invention, belonging to institute of the present invention
Scope defined in attached claim.
