Description

A kind of on-line measuring device of Surge Protector

Technical field

The utility model relates to a kind of on-line measuring device of Surge Protector, belongs to the apparatus for preventing thunderbolt field.

Background technology

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 lead of electronic equipment, signal 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 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 look-at-me, 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 microswitch 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 electron device detects.Its defective is: metering circuit itself has taken place to be electrically connected with the Surge Protector circuit, causes metering 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 temperature variation.
