Description
Technical field
The utility model belongs to lightning surge safeguard field.
Technical background
The line surge that the line surge of thunder and lightning and initiation thereof and other reason cause is to cause the major reason that electric/electronic device is aging and damage.The installation Surge Protector is one of important measures of lightning protection on the metallic circuits such as the power line of electronic equipment, holding wire and control line being connected in.In this technical field, a major issue that exists is at present: Surge Protector is in protection equipment, deterioration can take place gradually until thorough damage in the device of himself, or directly damages under excessive surge impact, or proximity switch type surge protective device produces afterflow; For power source surge protector, its damage or the phenomenon that causes damage have short circuit (comprise afterflow, below omit) and leakage current increase to cause to generate heat two kinds; For the signal Surge Protector, the phenomenon of its damage is generally Surge Protector to two kinds of the impedance increasing of signal transmission and surge protective device short circuits.Which kind of situation no matter occurs, all must in time surge protective device be spun off from circuit, otherwise phenomenons such as burning, switch trip power failure, signal transmission fault will occur.For those to the thunder and lightning sensitivity equipment, particularly in thunder and lightning season or area occurred frequently, be flagrant, 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 change 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; 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; thunder and lightning disaster investigation statistics to nearly 10 years every profession and trades shows; a lot of Surge Protectors have damaged but are undiscovered; the situation that causes thunder and lightning to break the accident of equipment thus accounts for significant proportion; though therefore this problem seems very little, is related to the safety of the electronic information of each department every profession and trade conscientiously.
It is as follows to address the above problem existing technical method and shortcoming at present:
One, generally adopts the method that regularly Surge Protector is detected; detect general every year before and after thunderstorm season; but this method usually can not play effect; this is because after regular inspection, and 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 regular detection, can not effectively be detected.
Two, heat is set in power source surge protector inside and takes off mouthful device and in its sensitive switch that links, 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 that this method exists is: 1, surge suppression device deterioration or damage to produce and be enough to make the energy that takes off mouthful device 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.
Three, getting involved the Surge Protector circuit with electronic device detects.Its defective is: 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 is for the problems referred to above have proposed a solution, and 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 temperature information that therefore can support judgement is inadequately fully with direct to the surge suppression device variations in temperature.
The utility model content
In order effectively to solve the above prior-art problems, the utility model proposes a kind of can be easy for installation, reliability is high, detect sensitive part.
Owing to when the electric current that changes flows through conductor, around conductor, can produce magnetic field, and size of current is relevant with the variation in magnetic field.Therefore can carry out magnetic field detection by loop, realize detection the lightning current on the Surge Protector to surge suppression device,
The technical scheme that solves the problems of the technologies described above is: the Surge Protector of the utility model band checkout gear; comprise shell (6), magnetic strength unit (1), conversion of signals transmission unit (2), surge suppression device (4); described magnetic strength unit (1) is close to the path (3) of surge suppression device (4) and installs; described magnetic strength unit (1) is connected with conversion of signals transmission unit (2), and described conversion of signals transmission unit (2) connects outside signal processing apparatus.
Described conversion of signals transmission unit (2) comprises A/D change-over circuit and circuit for transmitting digital signals, and described conversion of signals transmission unit (2) connects outside signal processing apparatus or access information network.
Shell (6) is provided with the detection lead-out terminal, and the information after described conversion of signals transmission unit (2) is handled passes to outside signal processing apparatus by detecting output point.
Described magnetic strength unit (1) is the loop that comprises the magnetic strength device.
Described conversion of signals transmission unit (2) is in the shell (6) with surge suppression device and magnetic strength unit.
Described conversion of signals transmission unit (2) can be installed in the separate housing outside the shell (6) at surge suppression device and place, magnetic strength unit, becomes an independent detection module.
Described conversion of signals transmission unit (2) connects one or more magnetic strengths unit (1).
Described magnetic strength unit (1) and the electric not conducting of surge suppression device (4).
Advantage of the present utility model is:
One, the state of Surge Protector can be detected by online in real time.
Two, effectively solve the surge suppression device deterioration that existing detection method exists or do not produce the energy that is enough to make the trip gear action when damaging, caused can not the report to the police problem of output of alarm unit.
Three, 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.
Four, can detect the state in the record surge suppression device damage process and the reason of damage, for lightning protection provides full and accurate data message.
Five, the class signal Surge Protector has been realized online detection.
Six, measuring circuit itself does not have with the Surge Protector circuit and is electrically connected, and the problem of having avoided measuring circuit to be damaged in advance by lightning surge has also been avoided because the intervention of measuring circuit makes the class signal Surge Protector produce the problem of loss of signal and fault point.
