Description
Technical field
It is used to, using the overvoltage arrester in the electric current supply unit of low voltage electric network, carry shell the present invention relates to a kind of
The arc combustor of body, two electrodes relative to each other and construction in the inside of housing, wherein, it constructs between two electrodes
There is spark gap, so as to form electric arc between two electrodes in the case of spark gap is lighted.
Background technology
Here the chief component of the overvoltage arrester of referred to type is spark gap, in the feelings of the overvoltage determined
It is responded in condition, wherein, electric arc is formed between two electrodes when lighting spark gap.Such overvoltage arrester is especially
Ground is used in the region of the principal current supply unit of low voltage electric network, because it is with high discharge capability.Here, it is very high and
What is steeply risen has until the electric current of the value of thousands of kA scopes is flowable to cross spark gap.Due to herein in overvoltage arrester
Inside in the pressure and power that occur, such overvoltage arrester is usually placed in pressure-resistant housing.
Although the overvoltage arrester with spark gap has the advantages that high dash current bearing capacity, also have
It is relatively high and the shortcomings that be not especially constant operation voltage.Therefore, difference has been used in order to light spark gap for a long time
The igniting assisted parts of type reduces the operation voltage of spark gap or overvoltage arrester by means of the igniting assisted parts.
(with or without igniting assisted parts is used) in the overvoltage arrester of referred to type, spark gap is being lighted
In the case of, it forms low-impedance connection between two electrodes via electric arc, desirably, treats derived great instantaneous current stream
It is dynamic to cross the connection.However, in the case of there are network voltage, unexpected power grid following current (Netzfolgestrom)
Also it is flowable to cross the low-impedance connection, so as to make every effort to eliminate electric arc as quickly as possible after discharge process terminates.One
The possibility that kind is used to implement the target is, increases arc length and thus increases the electric arc after spark gap response
Ignition voltage.Another possibility that electric arc is eliminated after discharge process is, by the cooling effect of insulating material wall and
Electric arc is cooled down by using aerogenesis insulating materials.Thus arc ignition voltage is also improved.
For inhibiting the desired high arc ignition voltage of power grid following current with treating that derived very high electric current is total to
Same to cause, the power conversion in arc combustor is very high.Amplitude and impulse form and corresponding electricity depending on impressed current
Depending on arc voltage, the energy being introduced into overvoltage arrester can be several 10kJ herein.The energy is partly issued to encirclement electricity
At the insulating materials of arc chamber (Lichtbogenkammer), wherein, absorbed energy causes material part scaling loss.In order not to by
This damages the insulating materials of enclosing electric arc room too fast and too strongly, which must have very high hot durable with machinery
Property.Another part of energy is issued to via heat transfer in environment, wherein, which holds on the length of pulse to be discharged
The continuous time is very long, and thus the energy being introduced into during discharge process in arc combustor is only very slowly reduced.
A kind of overvoltage arrester as known to 103 38 835 A1 of file DE, wherein, electrode is axially opposite each other and puts,
And arc combustor is radially surrounded by insulator materials at least partly.It is thus prevented in the case of the overvoltage arrester
The appearance of power grid following current so selects greatly distance between two electrodes so that arc ignition voltage is more than pre-
The network voltage of phase.In order to the operation voltage for making the overvoltage arrester will not be due to two electrodes of spark gap it is relatively large
Distance and it is excessive, set igniting assisted parts, the desired operation voltage of overvoltage arrester is can adjust by the igniting assisted parts.
Spark gap rekindles in order to prevent, in the case of known overvoltage arrester, is provided in the housing
Cooling duct, in the case of discharge process, the gas of ionization generated in arc combustor by electric arc, hot should lead to
The cooling duct is crossed to be exported from housing.In order to enable the gas flowed out from housing does not have excessively high temperature, cooling is logical
It road must long enough.In the case of the overvoltage arrester as known to 103 38 835A1 of file DE, thus this is realized, i.e.,
Housing is configured to two-piece type, and two of which half-shell is arranged coaxially with each other.Here, it is disposed with spiral shape between two half-shells
Cooling duct, plasma can flow through the cooling duct and simultaneously the cooling duct can be used for two half-shells is made mutually to be screwed on.
Housing component being arranged coaxially with each other by two due to housing, being mutually screwed on is formed, in order to ensure enough machines
Tool stability, the wall thickness of two housing components must be relatively large, this generally causes the relatively increased overall diameter of housing.However, by
In desired high arc voltage, the energy conversion within overvoltage arrester is also very high, so that housing and used
Material, in particular in the region of arc combustor under high heat and mechanical load.
The content of the invention
Therefore it is an object of the invention to provide a kind of overvoltage arrester, it has been avoided as much as wherein above-described
Shortcoming.In particular, the energy being introduced at this during discharge process by high energy pulse in arc combustor should be as quick as possible
Ground is issued in environment.
In the case of overvoltage arrester according to the present invention, thus which realizes, i.e. arc combustor at least portion
Ground is divided to be surrounded by transparent material, so as to which after spark gap is lighted, making can be from electricity by the energy of the radiation emission of electric arc
The direction of housing is reached in arc combustion chamber by the transparent material.By it is making that arc combustor insulated at least partly,
Transparent material limits, and the part that the energy in arc combustor is introduced into the case of discharge process can be more quickly from electricity
Arc removes in combustion chamber, reduces the load of the material of enclosing electric arc combustion chamber as a result,.It also reduces and is discharged overvoltage as a result,
The structural requirement of device.
In order to make the radiation radiated by electric arc as big as possible partially across transparent material, in the wavelength of the radiation of electric arc
The transmissivity of transparent material is average very high in scope, wherein, transmissivity is preferably more than 70%, is more than 80% in particular.Due to
For the major part of the radiation of arc-plasma or electric arc in the wave-length coverage of 100nm to 4500nm, transparent material should be preferably
Averagely there is 80% or higher high-transmission rate in the wave-length coverage.Since the transmissivity of material is related to wavelength, this meaning
It, the transmissivity of material is not uniformly high in the entire wave-length coverage of the radiation of arc-plasma or electric arc.However work as
It is enough, so that the transmissivity in the subregion of the wave-length coverage of arc radiation when transmissivity is average corresponding high
Also there can be relatively low transmissivity.It is important in this that the energy as much as possible for the radiation emission for passing through electric arc can be from electric arc
The direction of housing is reached in combustion chamber by transparent material.
Within the scope of this invention it has proven convenient that for the transparent material, especially excellent crystalline ceramics, in particular can be used
Oxide ceramic, because it is with high transparency within relevant wavelength and in addition also with high heat and mechanical load
Property.It turns out to be herein and is particularly advantageous to use zirconium oxide (ZrO2), in particular polycrystalline zirconium oxide and use transparent point
Spinel ceramics (MgO-Al2O3).Generally speaking, there are a variety of high-effect ceramics, not only have the required high transparency but also
With sufficiently high heat and mechanical load, so as to which it can be used as enclosing electric arc burning in overvoltage arrester according to the present invention

Case is arranged to, and transparent material is surrounded by the material through coloring, wherein, the transmissivity of the material through coloring is less than transparent material
Transmissivity.Cause using with the material through coloring compared with low transmissivity, one of the energy by the radiation of transparent material
Divide and absorbed in the material through coloring of the encirclement transparent material.So, only also seldom energy penetrates into the neighbour of housing
It is connected in the region at the material through coloring, so as to only must also also absorb the radiation left from arc combustor at this
Energy very little part.Thus correspondingly less heated by force in the region of housing.By using the material through coloring,
Thus the volume of the material for the energy for absorbing radiation wherein is significantly increased, so as to be shown in the case of identical energy introducing
It writes and reduces the not only temperature rising in the material through coloring but also in adjacent housing.
The coloring of material through coloring can be uniform substantially in the whole thickness of material.However, it is preferred that it uses
The material being colored gradually or step by step surrounds transparent material.Here, gradually or the transmission of material that is colored step by step
Rate reduces from inside to outside to the direction of housing.It is transparent in being adjacent to for the material gradually or step by step being colored wherein as a result,
Material at region in, transmissivity is maximum, wherein, transmissivity in this region is again smaller than the transmissivity of transparent material.
By using gradually or step by step the material that is colored replaces the material of uniform coloring to realize, the energy of radiation it is only less
Part is absorbed in the transparent material of adjoining, and the major part of the energy radiated the material through coloring farther away from
It is absorbed in region or in the region of the adjoining of housing.
Not only in the material context for using uniform coloring but also using the feelings of material that gradually or step by step are colored
Further preferably it is arranged in condition, which has thermal capacity as high as possible.Thereby guarantee that, do not cause on the whole material and
Thus the too strong heating of overvoltage arrester.
Overvoltage arrester according to the present invention preferably has the igniting assisted parts being arranged within housing, including at least
One igniting element and ignitor.Igniting element and ignitor are in herein with arc combustor to be contacted, wherein, igniting member
Part is on one side with an electrode and being conductively connected with ignitor on another side.Lighting the feelings in auxiliary firing portion
In condition, electric current flows to second electrode from the first connection part of overvoltage arrester via housing, ignitor and igniting element first
Or second connection part.Here, electric current stream (Stromfluss) causes electric discharge via igniting element or causes in ignitor with closing
The initial arc being coupled between the electrode of igniting element, afterwards this cause lighting for spark gap between two electrodes.
In order to ensure high mechanical stability and can reliably control the power occurred in the case of discharge process, housing
Preferably it is formed from steel by metal, in particular.In addition, housing is preferably cylinder, so as to arc combustor preferably
It is configured to cylinder.So arc combustor is axially by two electrodes surroundings and radially by transparent material or transparent
Material and gas exhausted material surround.In addition, housing is preferably configured to two-piece type, wherein, such as housing can be by the first of pot type
