A kind of interior detection device of Surge Protector
Technical field
The present invention relates to a kind of interior detection device of Surge Protector, belong to the surge guard technology field of electronic electric equipment.
Background technology
Thunder and lightning is a kind of special weather phenomenon of aloft being discharged and being caused by charged cloud.The line surge of thunder and lightning and initiation thereof is to cause the major reason that electric/electronic device is aging and damage with the line surge that other reason causes, and it threatens the safe and stable operation of every field electronic informations such as building, railway, civil aviaton, communication, industry control, military affairs.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 at present is: Surge Protector is in protection equipment; Deterioration can take place gradually until thorough damage in the device of himself, or under excessive surge impact, directly damages, 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) to cause with the leakage current increase and 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 device of surge protector short circuits.Which kind of situation no matter occurs, all must in time device of surge protector be spun off from circuit, otherwise phenomenons such as burning, switch trip power failure, signal transmission fault will occur.Therefore; To the thunder and lightning apparatus sensitive, in thunder and lightning season or area occurred frequently, is flagrant for 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 change immediately; The 2nd, reflect detected problem in time, Surge Protector is made backup protection.
This shows,, need monitor in real time, and then when the surge protective device deterioration is damaged, in time take measures, guarantee the operate as normal of system line the surge protective device of its inside for the Surge Protector of being installed.
It is following to address the above problem existing technical method and shortcoming at present:
Adopt to measure components and parts and be installed in the Surge Protector, the physical parameter of surge protective device is detected, and export measurement and control unit analysis to, show, control etc.Above technical method still has problems: 1, measure components and parts and be installed in the Surge Protector, when surge current is released, be prone to cause measuring the interference or the damage of components and parts, make measurement result inaccurate, cause false alarm, misoperation; 2, the measurement component parameter kind selected for use of different device of surge protector has nothing in common with each other, and makes in the product design manufacture process type selecting complicated; 3, measure components and parts and surge protective device and independently be installed in the Surge Protector, take the inner space, line connecting relation is complicated, the fault point increases, and installation procedure increases, difficulty increases.
Summary of the invention
For the above problem in the technology is used in effective solution at present; The present invention proposes a kind of interior detection device of Surge Protector; Described checkout gear can not damaged by the lightning surge through surge suppression device, and can in time carry out backup protection, has solved the difficult problem of prior art.
The interior detection device that the purpose of this invention is to provide a kind of Surge Protector; Can realize the surge protection function and detect output function; In physical quantity such as the temperature that electric current, device of surge protector produced, infrared ray, discharge arc light and space electric field or the magnetic field that can pass through surge protective device or these physical quantitys one or more detect in real time and export detecting unit to through detection terminal and carry out analyzing and processing and in time carry out backup protection, are convenient to install and select for use.
The present invention adopts following technical scheme to realize:
A kind of interior detection device of Surge Protector comprises detection means (7), detects loop (2), detects lead-out terminal (1).
Said device of surge protector (6) is installed in the housing (3), is electrically connected with detection means, and housing (3) is installed in the lightning-protection module (4), and lightning-protection module (4) is installed on the base; Detection device is installed in the lightning-protection module (4) of Surge Protector in said, and detection means (7) is as in the housing (3), and detection means (7) is connected to detection lead-out terminal (1) through detecting loop (2).
Said device of surge protector (6) can be one or more devices of piezo-resistance, discharge tube, TVS etc.
Said detection means (7) can be one or more in the transducers such as temperature, light, magnetic, infrared, electric power.
Said housing (3) is different different with detection mode (temperature, light, magnetic, infrared, electric power), adopts semi-enclosed or totally enclosed type.
Be provided with the terminal that is electrically connected with device of surge protector (6) in the said housing (3), can adopt modes such as welding, lead connection, grafting to be electrically connected.
The invention has the advantages that:
1. the problem that has effectively solved the surge suppression device deterioration that the detection method of existing Surge Protector exists or failed in time to find when damaging.
2. can know in time that Surge Protector meets with the situation of thunderbolt, thereby whether the prevision Surge Protector lost efficacy soon, so that carry out maintenance work in advance.
3. the lightning protection component damage process of Surge Protector and the source of damage can records to be detected.
4. Surge Protector can be realized remote real-time monitoring.

Like figure, the 1st, detect lead-out terminal, the 2nd, detect loop, the 3rd, housing, the 4th, lightning-protection module, the 5th, base, the 6th, device of surge protector, the 7th, detection means.
Embodiment
Below in conjunction with accompanying drawing and embodiment embodiment is described
A kind of interior detection device of Surge Protector comprises detection means (7), detects loop (2), detects lead-out terminal (1).
Working method:
1, said interior detection device is installed in the lightning-protection module (4) of Surge Protector, and detection means (7) is as in the housing (3), and detection means (7) is connected to detection lead-out terminal (1) through detecting loop (2);
2, said device of surge protector (6) is installed in the housing (3), is electrically connected with detection means, and housing (3) is installed in the lightning-protection module (4), and lightning-protection module (4) is installed on the base.
The present invention utilizes the characteristic of surge current, adopts cleverly circuit and structure to realize the collection to variable, has realized that it detects employing non-cpntact measurement device to surge protection.
Utilizing technical scheme of the present invention, reach the corresponding techniques effect, perhaps in the technical scheme equivalents that does not break away under the design philosophy of the present invention, all is within protection scope of the present invention.
