Description
Technical field
The utility model belongs to the lightning surge protection field in the electric/electronic device field.
Technical background
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 lead of electronic equipment, signal 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, but is related to the major issue of each department every profession and trade electronic information safety conscientiously.
At present, as follows for the defective that addresses the above problem the method taked and technical scheme and existence thereof:
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 look-at-me, even so when regularly detecting, can not effectively be detected.
Two, the microswitch 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.
Three, getting involved the Surge Protector circuit with electron device detects.Its defective is that 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 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 temperature information that therefore can support judgement is inadequately fully with direct to the surge suppression device temperature variation.
