The lightning current measurement system collects, transmits, analyzes and processes data to obtain the result and provides a complete and efficient solution; and the system has high detection accuracy and efficiency.
Description
Technical field
The present invention relates to the electric power electric field, relate in particular to the system in a kind of lightning current protection field.
Technical background
Thunder and lightning is a kind of special weather phenomenon of aloft being discharged and being caused by the cloud of being with point.Thunder and lightning is the major reason that causes electronic equipment to damage, and it threatens the safe and stable operation of every field electronic informations such as building, railway, civil aviaton, communication, industry control, military affairs.Lightning protection is one of effective measure that addresses the above problem, in the present lightning protection field, the associated signal parameter of thunder and lightning such as electric signal and magnetic signal obtain and relative accuracy becomes very one of the key link, not only relate to normally releasing of thunder and lightning, influence the normal operation of personal safety, device security and system; And in the perspective study of lightning protection, also need the parameter information of thunder and lightning is carried out a large amount of basic work of researching and analysing.
Still there be not at present direct equipment and method at the lightning current Data Detection, conventional method has only ex-post analysis and estimation, promptly by adding up the damaged condition of lightning protection in this thunder and lightning zone, analyze and assess the parameter information of this regional lightning current, for lightning protection is from now on made advisory opinion.
The shortcoming of existing these indirect metering systems has:
1. indirect evaluation method is random big, as a result out of true;
2. the damaged condition of lightning protection has randomness, can not react the data message of lightning current more really; And measuring and calculating must be a prerequisite with the damage of lightning protection, and the cost of this measuring and calculating is too high;
3. this measurement is property afterwards just, can not real-time analysis, thus can not grasp up-to-date data message at any time;
4. also from the information acquisition to the information analysis, do not handle at present a whole set of technical scheme of information result output.
Summary of the invention
In order effectively to overcome the above problems, the invention provides a kind ofly detect accurately, efficient is higher, the lightning current measurement system that can detect in real time.
The present invention realizes by the following technical solutions: a kind of lightning current measurement system of the present invention, comprise host computer and measuring terminals, described measuring terminals is arranged in the thunder and lightning surveyed area, be connected by transmission system between described measuring terminals and the host computer, the detection data of described measuring terminals pass to host computer by transmission system and obtain handling.
The transmission mode of described transmission system is one or more in transfer bus, optical fiber or the wireless transmission.
Described host computer is provided with the communication management unit, and it controls the information transmission between described measuring terminals and the host computer.
Described host computer is provided with analysis and processing unit, its with the information that described measuring terminals passes to store, calculate, analysis, display result and record.
Described control module can be controlled the Measuring Time and the frequency of measuring terminals, realizes intellectualized operation.
Be provided with current measuring device in the described measuring terminals, described thunder and lightning surveyed area is the lightning current path, the signal that arrester that install at place, described lightning current path or downlead obtain passes to described current measuring device, and described current measuring device passes to host computer again and obtains handling.
Be provided with magnetic field measuring device in the described measuring terminals, described thunder and lightning surveyed area is the lightning current near zone, and described magnetic field measuring device passes to host computer with the field signal that obtains and obtains handling.
Described analysis and processing unit includes, one or several in storage module, computing module, analysis module, display module, the logging modle.
Described measuring terminals is at least one.
Compared with prior art, the invention has the advantages that:
1. directly detect at lightning current, improved accuracy than the indirect analysis estimation;
2. this measuring method needn't be with the damage of lightning arrester as prerequisite, and the measuring and calculating precondition is low, and has reduced cost;
3. the data of terminal collection can send to the host computer analyzing and processing in real time, have accomplished the real-time update of data, for lightning protection provides up-to-date first hand data message;
4. from the sense terminals image data, to transmission system Data transmission quick and precisely, handle up to obtaining the result to the efficient analysis of host computer again, the present invention provides one to overlap complete, solution efficiently to the data input and output in lightning protection field.
5. the control module of host computer can be controlled the Measuring Time and the frequency of measuring terminals, realizes intellectualized operation.
