Description
Technical field
The present invention relates to a kind of EHV transmission line side peak point current measurement apparatus, especially relate to a kind of EHV transmission line side peak point current wireless monitoring device。
Background technology
Lightning Disaster is the one in a kind of unavoidable natural disaster of current facing mankind。The economic loss caused is very huge, and numerous people life and safety are constituted a serious threat。
Meanwhile people to the exploration of thunder energy also in the middle of constantly furtheing investigate, prior art has thunder-strike current and thunderbolt numeration writing function, it is substantially all the transformer station being mounted in secondary grid side or outdoor depopulated zone, therefore distance thunderbolt point is too remote, therefore the firsthand information of high-pressure side thunderbolt peak point current cannot be real-time monitored, it is impossible to accurately schemes of prevention against lightning is provided the real time data of thunder and lightning peak point current。
Summary of the invention
It is an object of the invention to provide can be arranged on from lightning strike spot closer to high mountain on peak point current wireless monitoring device。
The purpose of the present invention can be achieved through the following technical solutions:
A kind of EHV transmission line side peak point current wireless monitoring device, this device includes current sensor, power supply harvester, central processing unit, Wireless Transmitter, described central processing unit, Wireless Transmitter are electrically connected successively, and described current sensor, power supply harvester are all electrically connected with central processing unit。
Accompanying drawing explanation
Described current sensor is noninductive open-core type current sensor。
Described current sensor can arrange how many according to the quantity of transmission line of electricity。
Detailed description of the invention
Described power supply harvester is side inductive pick-up power supply。
Compared with prior art, the present invention has good reliability and safety, the advantage such as have high and low power consumption easy for installation, pressure, data are wirelessly transferred。
Fig. 1 is the structural representation of the present invention。
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail。
