Abstract
The invention relates to a magnetic energy detector for a surge protector. A magnetic field detector (4) is arranged on one side of a surge suppression device (2); when electric current flows through the surge suppression device (2), the magnetic field detector (4) detects a magnetic field and transmits information to a data processing unit (5), and the data processing unit (5) builds a model and analyzes magnetic energy signals to acquire energy of lightning stroke currents and the state of the surge suppression device (2) per se. The detector mainly comprises the surge suppressor (2), the magnetic field detector (4), the data processing unit (5) and an alarm terminal (6). The detector provides a simple and reliable detection scheme for detection and alarm of the surge protector. The detector has the advantages of repeated use and long service life.
Description
Technical field
The present invention relates to a kind of magnetic energy detector of Surge Protector.
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.On the metallic circuits such as power lead, signal wire and control line of connection and electronic equipment Surge Protector being installed is one of important measures of lightning protection.Surge Protector has been widely used in various fields, has important effect in lightning protection.The quality of its state then directly influences its lightning protection effect, thereby the safety of protection equipment is brought hidden danger.Therefore to the state of Surge Protector carry out that detection alarm just shows very important.
At present, the principle of work of the detection alarm unit of existing Surge Protector is that trip gear and the microswitch by Surge Protector inside moves output signal to realize its function, and then the fault of Surge Protector is reported to the police.The problem of taking above measure to exist is: 1, alarm unit is realized can only exporting a kind of parameter, and the reason of state in its damage process and damage all being can not determine the detection of the good and bad two states of surge suppression device only; 2, alarm unit adopts the trip gear in the Surge Protector to drive, only could output alarm signal when device failure, and irrecoverable, and detection alarm repeatedly; 3, the surge suppression device deterioration may not the generation group so that the energy of trip gear action, the alarm unit output of can not reporting to the police; 4, the energy of thunder-strike current and time still can't be analyzed by the output signal of alarm unit.
At the problems referred to above, main solution has a kind of patent of invention and two kinds of utility model patents.Patent of invention is " novel detection device of Surge Protector " (patent No.: 200710154021.9).Utility model patent is " a kind of on-line measuring device of Surge Protector " (patent No.: 200820137317.x) with " novel detection device of Surge Protector " (patent No.: 200720177057.4).
Summary of the invention
In order effectively to overcome the above problems, more solution is provided, the present invention proposes a kind of magnetic energy detector of Surge Protector.
The magnetic energy detector that the purpose of this invention is to provide a kind of Surge Protector.The changes of magnetic field that pick-up unit is produced when flowing through electric current by detecting in the conductor is carried out quantitative analysis to the state of current energy and device of surge protector, and will be shown on alarm terminals with this result who draws, for the user provides in time, reliable information.
The present invention realizes by the following technical solutions: according to maxwell theory, when electric current flows through conductor, can produce magnetic field around conductor.In device of surge protector one side detector for magnetic field is installed.When having surge current to flow through on the device of surge protector, detector for magnetic field can with this magnetic field detection to and it is analyzed accordingly, thereby draw corresponding warning message.This device mainly is made up of with alarm terminals (6) surge suppression device (2), detector for magnetic field (4), data processing unit (5).
It is characterized in that: surge suppression device (2) is serially connected with between input terminal (3) and the lead-out terminal (7), plays the effect of the surge current of releasing.Detector for magnetic field (4) is parallel to be installed on a side of surge suppression device (2) and to link to each other with data processing unit (5), and data processing unit (5) links to each other with alarm terminals (6) by data line.When not having surge current to flow through surge suppression device (2), produce without any magnetic field around it, detector for magnetic field (4) detects less than any field signal, is in idle condition.In case have surge current to flow through surge suppression device (2), can produce magnetic field rapidly around it and follow the variation of surge current and change.At this moment, detector for magnetic field detects magnetic field and the magnetic field parameter is passed to data processing unit (5).Quantitative model is handled, set up to data processing unit (5) in real time with the data that receive, finally the energy size that draws surge current according to the physical parameter and the variable quantity thereof in magnetic field and the status information of surge suppression device (2), and above information is sent to alarm terminals (6) in the lump together with release time of incident of this surge current, make that the user can obtain timely, comprehensive warning message.
The invention has the advantages that: according to the principle of electric magnetisation, catch in the magnetic field that utilizes detector for magnetic field (4) to produce when flowing through surge current on the surge suppression device (2), draws warning message and show on alarm terminals (6) by data processing.This detection method is more rapid, sensitive than other detection methods (for example patent 200720177057.4 serviceability temperature detection methods), the reliability height, and restorability is strong, can use repeatedly.

Embodiment
The concrete scheme of embodiment is as follows:
Surge suppression device (2) is serially connected with between input terminal (3) and the lead-out terminal (7), plays the effect of the surge current of releasing.Detector for magnetic field (4) is parallel to be installed on a side of surge suppression device (2) and to link to each other with data processing unit (5), and data processing unit (5) links to each other with alarm terminals (6) by data line.When not having surge current to flow through surge suppression device (2), produce without any magnetic field around it, detector for magnetic field (4) detects less than any field signal, is in idle condition.In case have surge current to flow through surge suppression device (2), can produce magnetic field rapidly around it and follow the variation of surge current and change.At this moment, detector for magnetic field detects magnetic field and the magnetic field parameter is passed to data processing unit (5).Quantitative model is handled, set up to data processing unit (5) in real time with the data that receive, finally the energy size that draws surge current according to the physical parameter and the variable quantity thereof in magnetic field and the status information of surge suppression device (2), and above information is sent to alarm terminals (6) in the lump together with release time of incident of this surge current, make that the user can obtain timely, comprehensive warning message.
