Device damage, current method of overvoltage protection is to install surge protector on the line, but surge protector at this stage
Come in AC power development, what its inspection and test method were continued to use is the method for inspection of low-voltage alternating-current distribution system, though
The surge protector that right photovoltaic DC circuit is used is identical on lightning protection theory and earial drainage mode, but in surge protector
There is great difference in failure mode, alternating-current system has zero passage arc extinguishing to design, direct current is protected then without zero passage in surge
Shield device fail when, its dropout arc extinguishing action obviously and exchange dropout arc extinguishing difference.
What this patent set Thermal Cutoffs for L poles, a very hot fusing solder joint of N and instantaneous short circuit can be quick
Fusing arc extinguishing path, forms three dropout surge protectors, surge protector when the very hot fusing solder joint dropout arc extinguishings of N fail,
Trip point may produce electric arc, because the DC voltage that dc source does not have zero crossing voltage, dropout point electrode can be tieed up always
This electric arc is held, in the presence of mechanical force, the electrode of trip point is connected to the quick of patent setting to apparatus of the present invention after threading off
Fuse, make power supply L (+) the extremely short roads of N (-), reach the effect of moment arc extinguishing.So that the active arc extinguishing of this patent
Three dropout surge protectors are adapted to alternating current-direct current electricity system.
The content of the invention
The technical problem to be solved in the present invention be to provide can instantaneous short circuit quick fuse path, reach the effect of moment arc extinguishing
Active arc extinguishing three dropout surge protectors.
To solve the above problems, the present invention is adopted the following technical scheme that：
A kind of three dropout surge protectors of active arc extinguishing, including piezo-resistance M, fastp-acting fuse E, Thermal Cutoffs T,
Horn X and mechanical trip arm Y, the Thermal Cutoffs T series connection electrode L and piezo-resistance M, the fastp-acting fuse E and pressure
Quick resistance M is in parallel, and mechanical trip arm Y can be in the presence of mechanical force, and it is fast that the electrode of N poles trip points B is connected to after threading off
Fast fuse E, makes the positive pole L of power supply and negative pole N short circuits, reaches the effect of moment arc extinguishing, the horn X and mechanical trip arm
Y is connected, and the fastp-acting fuse E two ends are provided with node A and arc extinguishing connects node D, and trip point B is provided with the horn X
With node C, the trip point B connects with piezo-resistance M, and the Thermal Cutoffs T connects electrode L and piezo-resistance M, the temperature
Degree fuse T and piezo-resistance M is connected to point G, piezo-resistance M resistance is reduced and is shunted electric current, prevents from being subject to excessive
Instantaneous voltage destruction or disturb, the instantaneous voltage wound mayed to circuit of mutation because electric power supply system can be protected
Evil,
Further, the node A is connected with positive pole L, the normal connection of holding circuit.
Further, the node C is connected with negative pole N, the normal connection of holding circuit.
Further, the Thermal Cutoffs T fusing-off temperatures are arranged between 110 DEG C -150 DEG C.
Further, the fastp-acting fuse E blowout currents are less than 2A, when electric current is more than 2A, circuit can be carried out
Protection.
The technical scheme have can instantaneous short circuit quick fuse path, the characteristics of reach moment arc quenching effect.
The beneficial effects of the invention are as follows：The piezo-resistance M resistance of setting is reduced and is shunted electric current, prevents from being subject to
Big instantaneous voltage destruction or interference, can protect shield because the instantaneous voltage mutation of electric power supply system is mayed to circuit
Injury, mechanical trip arm Y can be in the presence of mechanical force, the fastp-acting fuse E that the electrode of trip point B is connected to after threading off,
Make the positive pole L of power supply and negative pole N short circuits, reach the effect of moment arc extinguishing.

Specific embodiment
Refering to shown in Fig. 1-Fig. 3, a kind of three dropout surge protectors of active arc extinguishing, including piezo-resistance M, quick fuse
Device E, Thermal Cutoffs T, horn X and mechanical trip arm Y, the fastp-acting fuse E are in parallel with piezo-resistance M, the electrode
Arm X and mechanical trip arm Y is connected, when in use, when surge protector fails, piezo-resistance M heatings, in trip point B temperature
Rise, the connection scolding tin of fusing trip point B, under mechanical trip arm Y pulling force F effects, node C is pushed to node D, in this process
In, can there is electric arc between trip point B and node C, under dc source effect, limited by trip point B spaces, electric arc is present not
The risk of the automatic arc extinguishing of energy, when node C is pulled to D points, node A, node C make node A, node C short by fastp-acting fuse E
Road, due to no potential difference between trip point B, node C, electric arc automatic distinguishing between trip point B and node C, node A, node C
Open circuit completely, reaches the effect of arc extinguishing open circuit, and the fastp-acting fuse E two ends are provided with node A and arc extinguishing connects node D, described
Trip point B and node C is provided with horn X, the trip point B connects with piezo-resistance M, the Thermal Cutoffs T series connection
Electrode L and piezo-resistance M, the Thermal Cutoffs T are used as temperature backup, fail to realize that time point G heats up in above-mentioned functions,
Thermal Cutoffs T does temperature fusing.
The node A is connected with positive pole L, when in use, the normal connection of holding circuit.
The node C is connected with negative pole N, when in use, the normal connection of holding circuit.
The Thermal Cutoffs T fusing-off temperatures are arranged between 110 DEG C -150 DEG C.
The fastp-acting fuse E blowout currents are less than 2A, when dc source is applied directly on fastp-acting fuse E, soon
Fast fuse E quick fuses.
When in use, when surge protector fails, piezo-resistance M heatings, trip point B temperature rises, fusing trip point B
Connection scolding tin, under mechanical trip arm Y pulling force F effects, node C is pushed to node D, during this, trip point B and node
Can there is electric arc between C, under dc source effect, limit by trip point B spaces, electric arc presence can not arc extinguishing automatically wind
Danger, when node C is pulled to D points, node A, node C make node A, node C short circuit, trip point B, section by fastp-acting fuse E
Due to no potential difference between point C, electric arc automatic distinguishing between trip point B and node C, node A, node C are completely breaking, reach
The effect of arc extinguishing open circuit.
The beneficial effects of the invention are as follows：The piezo-resistance M resistance of setting is reduced and is shunted electric current, prevents from being subject to
Big instantaneous voltage destruction or interference, can protect shield because the instantaneous voltage mutation of electric power supply system is mayed to circuit
Injury, mechanical trip arm Y can be in the presence of mechanical force, the fastp-acting fuse E that the electrode of trip point B is connected to after threading off,
Make the positive pole L of power supply and negative pole N short circuits, reach the effect of moment arc extinguishing.
The above, specific embodiment only of the invention, but protection scope of the present invention is not limited thereto, and it is any
The change or replacement expected without creative work, should all be included within the scope of the present invention, therefore, it is of the invention
Protection domain should be determined by the scope of protection defined in the claims.
