Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Please refer to Fig. 1-3, a kind of traffic light control cabinet, including fixed frame 1, fuse 3, main traverse line 5, parallel wire 6 and absolutely
The front of edge protective shell 7, fixed frame 1 is successively fixedly installed with the second Surge Protector 21, the first Surge Protector 2 from left to right
With control circuit case 4, the bottom of fuse 3 and the top of control circuit case 4 are electrically connected, the top of the first Surge Protector 2
It is electrically connected with the first conducting wire 61, the outside of the first conducting wire 61 and one end of parallel wire 6 are electrically connected, the other end of parallel wire 6
It is electrically connected with the top of fuse 3, the outside of parallel wire 6 and the bottom of main traverse line 5 are electrically connected, the left end of the first conducting wire 61
It extending to the inside of insulation protection shell 7 and is fixedly installed with hose 71, the other end of hose 71 is electrically connected with extension wire 72,
The left end of extension wire 72 is electrically connected with connection plug 75, and the two sides up and down of extension wire 72 are electrically connected with conducting block 73,
The left side of conducting block 73 is electrically connected with high temperature Fuse assembly 74, and insulation protection shell is fixedly installed with conduction on the left of 7 inner cavity
Part 621, the inner cavity of conduct piece 621 are electrically connected with the second conducting wire 62, the left end of high temperature Fuse assembly 74 and the right side of conduct piece 621
Side is electrically connected, and the upper and lower surface of conduct piece 621 is fixedly connected with the inner wall of insulation protection shell 7, hose 71 and connecting spring
76 are in complete compressive state before the fusing of high temperature Fuse assembly 74, and the right end of the second conducting wire 62 runs through conduct piece 621 simultaneously
It is electrically connected with connection socket 622 compatible with connection plug 75, the left end of the second conducting wire 62 extends to insulation protection shell 7
Outside is simultaneously electrically connected with resistance unit 22, and the top of the bottom of the second conducting wire 62 and the second Surge Protector 21 is electrically connected.
Wherein, the front of extension wire 72 is fixedly installed with observation bar 78, and observation bar 78 extends to the outer of insulation protection shell 7
Portion, the front of insulation protection shell 7 offer loose slot 77 compatible with observation bar 78, using observation observation bar 78 in loose slot
Position inside 77 reduces staff so that facilitating testing staff judges the first Surge Protector 2 whether normal operation
The time of detection.
Wherein, high temperature Fuse assembly 74 is disposable fuse, and disposable fuse is lead-antimony alloy material, diameter
Value is five millimeters.Inversely, the bigger fusing time of electric current is about short for the fusing time of lead-antimony alloy and the size of electric current, and molten
The disconnected time finally close to 2 to 3 milliseconds, the existing discharging gap breakdown time be about 0. 1 milliseconds and 0. 5 milliseconds it
Between, so that the fusing time of high temperature Fuse assembly 74 is greater than the first Surge Protector 2 breakdown time, so that the first surge is protected
Device 2 is protected in normal state, there is no electric current inside high temperature Fuse assembly 74, so that the second Surge Protector 21 will not be by
It is influenced to high current, ensure that the second Surge Protector 21 not will receive always in normal state in the first Surge Protector 2
The high current frequency of occurrences is excessively high and damages, and ensure that the feasibility that the second Surge Protector 21 is implemented.
Wherein, the middle part of high temperature Fuse assembly 74 is ferrous metal bar, and the both ends of high temperature Fuse assembly 74 are disposable protect
Dangerous silk, the both ends of ferrous metal sense are fixedly connected with disposable fuse.When disposable fuse is fused by high temperature, metallic rod
It will fall off moment, and avoid high temperature Fuse assembly 74 and be difficult to melt to the greatest extent and cause connection socket 622 mutual with connection plug 75
The problem of contact, ensure that the second normally operation of Surge Protector 21.
Wherein, hose 71 is the conducting wire of bellows package, and insulating tube is in compression before the fusing of high temperature Fuse assembly 74
State.It is elongated so that 75 moving process of connection plug only needs hose 71 to extend, avoiding 75 moving process of connection plug needs
The mobile problem of the first conducting wire 61 is involved, the mobile influence to 7 external element of insulation protection shell of connection plug 75 is reduced.
Wherein, the shape of connection plug 75 is hemispherical.Spherical design is so that connection socket 622 and connection plug 75 connect
Contact area when connecing tends to maximize, so that the connection between connection socket 622 and connection plug 75 is more stable, ensure that
Its good electric conductivity.
In use, when if 2 internal component of the first Surge Protector is damaged by high current, if it is existing to occur high current again at this time
As fuse 3 fuses again, and current intelligent is flowed in insulation protection shell 7 by the first conducting wire 61, the temperature of high temperature Fuse assembly 74
Degree gradually rises, and in the predetermined time, high temperature Fuse assembly 74 is blown, and using the recovery of connecting spring 76, pushes and extends
Conducting wire 72 moves to left, so that connection plug 75 and connection socket 622 are in electrical contact, so that electric current enters the second Surge Protector 21
In, stream is unloaded using the completion of the second Surge Protector 21；
When timing maintenance control cabinet, position of the observation observation bar 78 inside loose slot 77, when observation bar 78 is located at activity
When the right end of slot 77, the first Surge Protector 2 and the second Surge Protector 21 are in normal condition at this time, when observation 78, bar
When the left end of loose slot 77, the first Surge Protector 2 and high temperature Fuse assembly 74, and the second wave of detection are only needed to change at this time
Surge protector 21 is whether normal operation.
