Specific embodiment
With reference to specific embodiment, the present invention is described in detail.Following examples will be helpful to the technology of this area
Personnel further understand the present invention, but the invention is not limited in any way.It should be pointed out that the ordinary skill to this area
For personnel, without departing from the inventive concept of the premise, some deformation can also be made and improve.These broadly fall into the present invention
Protection domain.
The invention discloses a kind of lightning protection assembly as shown in Figure 1, including airtight spark gap, temperature switch, low
Pressure discharge module, self-induction booster；
The low pressure winding of described temperature switch, low pressure discharge module and self-induction booster be sequentially connected in series formed with being followed by low
Press power path, described temperature switch is also connected with input supply terminal；
Described airtight spark gap is connected across between described input supply terminal and ground, is formed and described low pressure discharge path phase
Electrion path in parallel；
Wherein, described airtight spark gap is additionally provided with trigger head between input head and delivery, described self-induction booster
One end of high pressure winding be connected with described trigger head, the other end be grounded.The present invention passes through between self-induction booster and airtight spark
The trigger head of gap is connected, and triggers the unlatching in electrion path after realizing raising low-voltage.
Electrion path described in this patent is for low pressure discharge path, and described electrion path is just
On input power when normally open, voltage is more than the threshold voltage of airtight spark gap.
As shown in figure 1, airtight spark gap has three tungsten coppers electrode a, c, d, the position of three electrodes determine ad it
Between breakdown voltage be necessarily higher than between ac, cd, when puncturing arcing between any ac or cd, hermetic cavity electricity lead to ad it
Between be in conducting state.
While small current is discharged by low pressure discharge path, the voltage flowing through is 1.5-2 times by self-induction booster
It is added in after amplification on the trigger head of airtight spark gap, that is, be applied between the cd shown in Fig. 1.If the voltage after amplifying makes cd
Between puncture arcing, then airtight spark gap conducting.Therefore self-induction booster is played in this programme and is triggered by induced voltage
The effect of airtight spark gap triggering.
Self-induction booster utilizes the ascending mutation time induced voltage different from the primary and secondary number of turn of thunder-strike current to change
Principle, generation high pressure is sensed so that between airtight spark on the high pressure winding of self-induction booster by the current break between bd
Between the cd of gap, voltage, with respect to about 1.5-2 times of the voltage increase in the now low pressure winding of self-induction booster, causes airtight spark
The conducting in gap.
Lightning protection assembly also includes relay indicating light.One end of relay indicating light be connected to described temperature switch with described
Between low pressure discharge module, the other end is grounded.Relay indicating light can be neon lamp.

Close, described discharge tube connects described self-induction booster.
Described temperature switch is overheated electric fuse.Described temperature switch located at described varistor surface, for described
Disconnecting circuit during varistor superheat state.Described overheated electric fuse is adjacent to varistor, when varistor temperature overheating, institute
State overheated electric fuse to be blown, relay indicating light extinguishes simultaneously.
Described discharge tube is ceramic discharge tube.Ceramic discharge tube is in conducting state when both end voltage rises to certain value.
Described varistor is Zinc-oxide piezoresistor.Zinc-oxide piezoresistor when both end voltage rises to certain value is in
Low resistive state.
The principle of the present invention is in the case that residual voltage is less than airtight spark gap threshold value, using discharge tube, varistor
Also airtight spark gap can be opened while earial drainage and carry out earial drainage, thus improving the lightning protection capability to small current；In residual voltage it is higher than
In the case of airtight spark gap threshold value, airtight spark gap normally-open earial drainage to high current.
Airtight spark gap (s-gap) a point at least needs the lightning current of 3-5ka could use ad to d point starting current
Between short-circuit shape leakage current.When thunderbolt occurs to start reduced-current, the airtight spark gap leakage current of not enough startup is to ground.
This part overcurrent be enough to damage equipment, and therefore early stage overcurrent flows into through temperature switch and punctures varistor and put after b point
Fulgurite connects airtight spark gap trigger head by the high-voltage output end of self-induction booster through hardware, thus using less electricity
Stream can order about airtight spark gap and release, and have i step voltage switching mode spd and the lightning protection capability of ii level votage limit type spd simultaneously.
Based on same inventive concept, present invention also offers a kind of band compound lightning protection of trigger-type as shown in Figure 2
Device, including described lightning protection assembly and mounting seat；Described lightning protection assembly is installed in described mounting seat pluggablely,

Ground connection.
With the compound anti-lightening protector of trigger-type by low pressure discharge circuit, high voltage discharge circuit and triggering between the two even
Connect circuit composition, the advantage taking full advantage of different components and parts, play its effect.Constitute as Fig. 3 mesolow power-supply system level and
Level surge protection and specially designed.Small product size is little, and surge relieving capacity is big, and voltage protection level is low, fast response time.
Eliminate the restriction of connecting wire length between the installation of decoupler and level between conventional stage and level surge protector, especially suitable
It is combined between level and level surge protector two-stage and uses in the case of cannot meeting 10m wire mounting distance, save and sky is installed
Between, simplify mounting technique, optimize wire and connect.
It is the perfect combination body of lightning current spark gap and Surge Protector with the compound anti-lightening protector of trigger-type.Only take up
The standard module width spaces of 6 or 8, and the Surge Protector of red line product line can be coordinated to be used together without attached
Plus decoupling device, also can direct protection equipment.The design having double terminals with the compound anti-lightening protector of trigger-type simplifies
The work of wiring, need not be in load current add-on module group, the bus-bar set up in outfan improves other track installation devices
The probability that part is applied in combination.The band compound anti-lightening protector of trigger-type carries relay indicating light and module is pluggable, changes
Convenient.Varistor (voltage votage limit type), gap discharge formula (voltage switch is adopted inside the band compound anti-lightening protector of trigger-type
Type), triggers circuit gather together, there is the restriction ability of disconnected subsequent current, even if having predetermined short circuit current to occur, leading portion
Electric fuse will not disconnect.
Above the specific embodiment of the present invention is described.It is to be appreciated that the invention is not limited in above-mentioned
Particular implementation, those skilled in the art can make various modifications or modification within the scope of the claims, this not shadow
