Description
Technical field
The invention belongs to lightning surge safeguard field.
Technical background
Thunder and lightning is a kind of special weather phenomenon of aloft being discharged and being caused by charged cloud.Thunder and lightning is the major reason that causes electronic equipment to damage, and it threatens the safety of every field electronic informations such as building, railway, civil aviaton, communication, industry control, military affairs.Surge Protector is to be mainly used in the protection class device that suppresses lightning surge.The installation Surge Protector is one of lightning protection important measures on the metallic circuits such as the power line of electronic equipment, holding wire and control line being connected in.At present the each department every profession and trade all drops into a huge sum of money and purchase the installation Surge Protector in a large number every year.But in essence; Surge Protector is the device of a kind of " sacrificing oneself; protect others "; when Surge Protector suffers the lightning surge electric current; or long-term the use, must occur aging and damage, at this moment; Surge Protector has just lost the function of protection electronic electric equipment, impaired to a certain degree Surge Protector in addition may cause line interruption or short circuit.This to the thunder and lightning apparatus sensitive, in thunder and lightning season or area occurred frequently, is flagrant to those particularly, or even " fatal ".This has just caused the urgent demand of user: the one, know in time whether each Surge Protector is also playing due protective effect this moment, if not, then should safeguard replacing at once; The 2nd, know that Surge Protector has met with the situation of thunderbolt, that is to say, predict Surge Protector and whether soon lose efficacy, so that carry out maintenance work in advance.
This shows that because the user does not know the current state of each Surge Protector, lightning protection has just been become " blind person ", the lightning protection safety of electronic information just becomes unknowable thing.In fact, the investigation statistics that the thunder and lightning disaster of nearly 10 years all trades and professions is carried out shows that a lot of Surge Protectors have damaged but undiscovered, and the situation that causes thunder and lightning to break the accident of equipment thus accounts for sizable ratio.Though therefore this problem seems very little, is related to the safety of each department every profession and trade electronic information conscientiously.Therefore the state to Surge Protector detects very important that processing just shows with subsequent analysis.
At present, have following several for addressing the above problem method and the technical scheme taked:
One, generally adopts the method that regularly Surge Protector is detected at present; detect general every year before and after thunderstorm season, but this method usually can not play effect, and this is because after regular detection; possible Surge Protector is just broken by thunder and lightning at once, and follow-up thunderbolt will be smashed equipment.In addition, for the Surge Protector that is installed in the signal circuit, usually owing to not shutting down interrupt signal, even so when regularly detecting, can not effectively be detected.
Two, the sensitive switch that thermal release device is set in power source surge protector inside and links with it, switching value of output was reported to the police to the fault of Surge Protector by this switching value when cause thermal damage takes place power source surge protector.The problem of this its existence of method is: 1, surge suppression device deterioration or damage and may not produce the energy that is enough to make the trip gear action, the alarm unit output of can not reporting to the police at this moment.2, at the just possible output alarm signal of device failure, can not predict in advance; Reason to state in its damage process and damage all be can not determine; 3, be not suitable for the class signal Surge Protector; 4, the energy of thunder-strike current and time still can't be carried out analyzing and processing by special equipment.
Three, getting involved the Surge Protector circuit with electronic device detects.Its defective is that measuring circuit itself has taken place to be electrically connected with the Surge Protector circuit, causes measuring circuit to be damaged in advance by lightning surge.
Four, " novel detection device of Surge Protector " (patent No. zl200720177057.4) that is proposed by me proposed a solution for the problems referred to above.This scheme has tentatively solved the problem on line detection of Surge Protector.Its defective is: temperature switch can not accurately and timely reflect that still the state information that therefore can support the judgement surge suppression device is inadequately fully with direct to the surge suppression device variations in temperature.
Summary of the invention
In order effectively to solve the above prior-art problems, the present invention propose a kind of easy for installation, reliability is high, detect sensitive Surge Protector.
The technical scheme that solves the problems of the technologies described above is: the present invention includes shell (6), surge suppression device (4), infrared detection unit (1), conversion of signals transmission unit (2), the receive direction of described infrared detection unit (1) is towards surge suppression device (4), described infrared detection unit (1) is connected with conversion of signals transmission unit (2), described conversion of signals transmission unit (2) and the signal processing apparatus that is connected the outside.
When described surge suppression device (4) is gone up by surge current, can send infrared ray, and the big small form positive correlation of ultrared intensity and surge current, described infrared detection unit (1) receives the infrared ray that surge suppression device (4) sends, and and electric not conducting between the surge suppression device (4), outside line detecting unit (1) is transferred to conversion of signals transmission unit (2) by circuit (5) with signal, conversion of signals transmission unit (2) carries out this signal the A/D conversion and exports to outside data processing equipment by transmission circuit through lead-out terminal (7), conversion of signals transmission unit (2) can and surge suppression device (4) be installed in the same shell, also can be contained in the independent shell.
Electric not conducting between described infrared detection unit (1) and the surge suppression device (4).
Described conversion of signals transmission unit (2) comprises A/D change-over circuit and circuit for transmitting digital signals.
Described shell (6) is provided with and detects lead-out terminal (7), and the information after described conversion of signals transmission unit (2) is handled passes to outside signal processing apparatus by detecting lead-out terminal (7).
Described conversion of signals transmission unit (2) is contained in the independent shell.
Described conversion of signals transmission unit (2) connects more than one infrared detection unit (1).
The invention has the advantages that:
1. can in time grasp the situation that Surge Protector has met with thunderbolt, thereby whether the precognition Surge Protector lost efficacy soon,, solved the only difficult problem of ability output alarm signal after device failure of existing detection method so that carry out maintenance work in advance.
2. infrared detection unit itself and the electric not conducting of device of surge protector stopped when the lightning current earial drainage takes place the negative effect of transducer has been strengthened the reliability of equipment;
3. by the conversion of signals transmission unit information parameter after gathering is carried out necessary processing or conversion, make transmission back data accuracy increase, help next step analyzing and processing.
4. the state in the detection record surge suppression device damage process and the reason of damage in real time; For lightning protection provides full and accurate data message.
5. widely applicable, not only be suitable for the class signal Surge Protector, and be applicable to power supply class Surge Protector.
