Each in spacer 22 to 24 includes easy to break or brittle partition 90, in fig .9 it is apparent that such a
Partition.In this Fig. 9, it can be seen that such brittle partition 90 is by each tenon 26 in spacer 22 to 24 and insertion section 27
Interrelated, simultaneously by one of terminals 2 to 4 and one of moving contact 61 to 63 mutually insulated.By electric insulation gas hat 91 such as
Air is limited near each brittle partition 90, position it, thus complete that this brittle partition 90 performs at terminals 2
Electric insulation between one of one of 4 and moving contact 61 to 63.
It will be evident that short-circuiting device 1 has modularized design from foregoing teachings, this is good.
In Figure 5, each moving contact 61 to 63 each skew the most above and in terminals 2 to 4.Moving contact 61 is disposed
In loading between two continuous print terminals 2 and 3 or waiting space 92.Moving contact 62 is placed in another waiting space
In 92, this is spatially located between two continuous print terminals 3 and 4.
Additionally, each in moving contact 61 to 63 carries out electric insulation, described insulation by insulation assembly and terminals 2 to 4
Assembly includes being preced with 91 bodies that continue formed by spacer 22 to 24, sealing member 29 and gas.This insulation assembly is also by terminals 2 to 4
Electric insulation is carried out with static contact 60.Short-circuiting device 1 thus be in wait open position, in this position, it is not set up any short circuit.
Above-mentioned insulation assembly shows has sufficiently high impedance it is thus possible to resist the advantage being struck by lightning.Particularly, its
The impulse wave of 12kV can be born without there being any damage, and meet the requirement of IEC standard 60947-1.
When the short-circuiting device 1 opened as in Figure 5 is connected in alive circuit, around terminals 2 to 4, generation is big
Electric field and magnetic field.These can increase the risk of backfire pyrotechnic shell cartridge case 11.In short-circuiting device 1, if this risk is passed through
Do feature and effectively dissolved.On the one hand, bracket 30, particularly its pedestal 32, terminals 2 to 4 and pyrotechnic actuator 7 it
Between, particularly and perform between pyrotechnic shell cartridge case 11 effectively to insulate.On the other hand, compression-expansion room 81 and piston 51 are had benefited from
Along the positioned opposite of axle X-X ' and the driving that has benefited from the mobile link bar 50 with pulling motion T, there is no any moving contact
61 to 63 between this executor 7 and the most hithermost terminals i.e. terminals 2.Additionally, include two relative connecting rods
70, the clamping sub-component of clamping plate 73 and body 10 forms closed in itself and the conduction band around terminals 2 to 4.According to
The principle performed in the cage of referred to as faraday cup, this galvanic circle is considered to react on the propagation in described electric field and magnetic field.
Short-circuiting device 1 may be used in device, it is provided that is protected from electric arc, especially internal arc.This device may be similar to
In the device described in above-mentioned european patent application EP 2073229, and can include more than one arc-detection sensor with
And policy of Central Government and control unit.The latter is for sending the dropout instruction of pyrotechnic shell cartridge case 11, and this central location should receive by extremely
That a few sensor sends and for representing the signal of arc-detection situation.
The dropout of pyrotechnic shell cartridge case 11 quickly causes chemical reaction, thus produces wherein and drive gas.These
Gas is conducting to room 81 through passage 41, and within the extremely short time, they make pressure in room increase.In the first stage, this pressure
Increase, but piston 51 will not be driven immediately and be connected to the moving assembly of this piston.This cause this moving assembly by spacer 22 to
24 fix.When the pressure in room 81 is sufficiently high, the brittle partition 90 of these spacers ruptures together, thus release plunger 51 suddenly
With the moving assembly being connected to this piston 51.It is that be stored in discharge chambe 81 until the energy that these partitions occur fracture means
The driving energy discharged by this fracture is the highest, thus the direction shown in arrow T is to promote at a high speed piston 51 along Fig. 5.Easily
Crisp partition 90, through calibration, just can rupture when the pressure in room 81 reaches predetermined threshold.
It will be evident that brittle partition 90 meets several functions from foregoing teachings, this is particularly simple in entirety, cost
It is good with space hold aspect.Particularly, they are execution electric insulation before pyrotechnic actuator 7 is threaded off, and once
Having made pyrotechnic actuator thread off, then they the most directly participate in the operation of this executor 7.
In this respect, the fracture under setting pressure i.e. predetermined pressure of the brittle partition 90 makes it possible to realize considerably less closing
Conjunction time, especially less than 1ms, it is included in and uses detonation powder to produce the situation driving gas in pyrotechnic actuator 7.
The moving assembly being connected to piston 51 is promoted fast as this piston 51 itself.It includes moving contact, label
Be 63 that moving contact utilize driven along with the push rod 66 promoted by nut 53.By another push rod 66, this is dynamic tactile
63 drive moving contact 62 successively, itself promote on last push rod 66, thus on the extension 68 of static contact 60
Drive moving contact 61.
In the very short time after starting pyrotechnic shell cartridge case 11, the short-circuiting device 1 just Unclosing structure from Fig. 5 is converted into figure
Short-circuit structure in 6.Particularly, the closing time less than 1ms started from pyrotechnic shell cartridge case 11 Startup time is had been achieved with.
Additionally, moving contact 61 to 63 arrives substantially simultaneously at terminals 2 to 4.This causes the short circuit of out of phase actually
Be simultaneously rather than a succession of.On the contrary, in the device shown in Fig. 5 of above-mentioned international patent application WO 99/21255, no
Synchronous short circuit is exactly a succession of.
The moving assembly being connected to piston 51 includes multiple parts.Different from along the promotion of executor 7 rightabout, these portions
Part at the pedestal 32 towards bracket 30 and is promoted towards the body 10 of this executor 7.This results in multiple advantage, its
In advantage be exactly that risk that when short-circuiting device 1 operate parts from short-circuiting device 1 prominent is greatly reduced, this at secure context is
Very important.Towards the second advantage that pedestal 32 and body 10 promote, moving assembly is that the latter forms propulsive thrust or system
Kinoplaszm amount, as anvil block (anvil), this reduces and is transferred to combination retaining element in short-circuiting device 1 and in this short-circuiting device
The importance of the impact of reflection.
In figure 6, in each hole 20 being comprised in one of terminals 2 to 4 in moving contact 61 to 63, and in this hole
Radial clamping force is applied on the surface of 20.This causes very effective electrical contact.For above-mentioned international patent application WO 99/
Device shown in Fig. 5 of 21255 is just not the case.In this respect, it is even contemplated that effective operation of this device all has
Problem.In the device of patent application WO 99/21255, only movable short-circuit part actually may be exaggerated terminals
Hole, when highlighting from these terminals, often forms unitary tapered shape.This can cause the phenomenon known in ballistics.
The most in figure 6, moving contact 61 to 63 is connected with each other, and this can produce required short circuit.These moving contacts 61 to 63
Being also connected to static contact 60, this contact 60 is by conductor ground connection, and for illustrative clarity, this conductor is not shown.In a word, exist
In Fig. 6, terminals 2 to 4 are short circuit ground connection.
Can draw from foregoing teachings, the short circuit that short-circuiting device 1 performs is quickly neat and simultaneously or actually simultaneously.
Significantly, since at terminals 2 to 4 be compressed in these terminals at the Guan Bi location of short circuit of Fig. 6
In moving contact 61 to 63 between electrical contact highly effective, short-circuiting device 1 and then can bear between 10kA to 150kA rms
The electric current of intensity reach the short circuit of 100 to 500ms time period.This causes short-circuiting device 1 to be particularly applicable to protect high-power electrical setting
It is standby, although it is equally applicable to protect miscellaneous equipment, such as medium-voltage equipment.
But, according to the understanding of the initial inventor of the present invention, the short-circuiting device of prior art is only capable of and makes maximally about
