It is few to safeguard and maintenance cost.It is that the tip of temperature stabilization is generally known in the art and frequent by tungsten alloy manufacture and weldering
It is connected in pre- arc angle being made of copper.
The Siemens AG as known to 2013 document " product information/version 1.2.0/Nr.A6Z00029955871 " page 3
The earthed switch 8WL6144-1A of the traction emergency electric supply unit for alternating current 25kV be for drawing connecing for emergency electric supply unit
Ground switch, it has the first main contacts and movable second main contacts, wherein, movable second main contacts can be from the first master
Remove to constitute the air gap contact.Earthed switch itself is divided according to the standard in terms of its short circuit making classification.Here,
Described earthed switch 8WL6144-1A be designed as when in advance shut-off trolley wire, ensure again connect and check no-voltage when
Can just close and and then set up the earthed switch of ground state.Earthed switch is avoided to be switched to short-circuit shape by these measures
State makes it impaired or damages with this.
Additionally, as known to the product information structural series SICAT 8WL6144 of Siemens AG disconnect switch, it is matched somebody with somebody
It is provided with the arcing horn made by copper.Burn-on with quite bothersome Magna-Flash welding methods the burnup being made up of tungsten-copper alloy

The whole arcing horn new with installation, the combined floodgate arc extinction of regulation is ensured with this.
Opened for the ground connection supply of AC and DC formula traction load electric current and that the trolley wire with voltage should be accessed
Closing must be on the contrary resistance to connection short circuit with known earthed switch 8WL6144-1A.Nowadays, the characteristics of switch is main be,
Switchblade knife is so that speed higher is into contact and and then relatively enters when the instantaneous value of electric current is relatively low with the pre- starting the arc
Enter contact.For this example is the FES 3-20-1 B series of Driescher companies.
Main contacts rapidly enter or quick-make obtains the increased effect of known electric current because closing course is necessary
In time zone in the elevated lower area of electric current, so as not to the entrance of switchblade knife can be hindered due to electric power.However,
Switched described in swtich train 8WL6144-1 compared to Siemens AG it is higher due to requiring, so construction it is firmer and because
This is more expensive.Although nowadays checking the mark installed at last before earthed switch according to the voltage of five security regulations of EN50110
Standard, but still require the earthed switch (AEE of such as SBB) of the higher level with short circuit making performance.Its
Reason is, the time in the case of emergency shutdown not used for voltage inspection and be necessarily be formed within several seconds safe
State.Other reasonses are probably maloperation.
Ignore herein, an earthed switch is then also subjected to short circuit although short circuit is triggered, but only when power supply
Breaker by its short circuit identification in one or more transformer station turn off voltage and and then cut off short circuit current when, this connects
Ground switch just bears this load.
From the known earthed switch for drawing the model 8WL6144-1A of emergency electric supply unit, the invention solves the problems that
Technical problem be, there is provided a kind of earthed switch for being suitable for carrying out short circuit making repeatedly, it can be manufactured at low cost.
According to ground of the invention, the technical problem is solved by for drawing the earthed switch of emergency electric supply unit, and it has
First main contacts and movable second main contacts, wherein, movable second main contacts can from the first main contacts remove so as to
Constitute the air gap, it is characterised in that main contacts has pre- arc starter, its short circuit making for being suitable for earthed switch.
Advantage according to earthed switch of the invention is that the function phase of the earthed switch is compared with traditional earthed switch
There is extension, because being improved considerably according to the short-circuit combined floodgate stability of earthed switch of the invention.Its realization is due to short circuit
Do not ignited through main contacts, this make the service life of main contacts be extended and while ensure the relatively intact of main contacts and with this phase
The relative reduction closed is safeguarded.Ensure that pre- arc starter is made through the commutation of pre- arc starter during closing motion/connection is moved
For " sacrifice element " triggers short circuit.Pre- arc starter can easily be repaired according to loss situation, this operation in earthed switch
Cost advantage is provided with maintenance aspect.
Here, earthed switch is simply constructed, it is in the disconnect switch based on identical platform scheme and connects
Ground switch on the basis of and can be to manufacture at low cost.Because the earthed switch is in (in emergency) short circuit making
Without impaired or damage, so it especially need not often be safeguarded in operation.
Direct current is applicable not only to according to earthed switch of the invention to run, and be also applied for alternating current operation.
According to earthed switch of the invention preferred embodiment in, pre- arc starter be arranged in main contacts top.
So it is favourable, because because main contacts is not at being ensure that to main contacts in the region that the heat of the arc column of appearance rises
Protection.Ensure that the bottom point of electric arc is always located in being advised for this accordingly for pre- arc starter by the minimum principle of electric arc with this
On fixed tip.
According to earthed switch of the invention it is further preferred embodiment in, pre- arc starter is touched for each
Point all has a pre- starting the arc facility.
Here, pre- starting the arc facility itself is not in contact with, but design in this wise in structure so that by more than critical field strength
Lighting for causing reliably carry out and result in electric arc.Selected depending on electrical voltage system and rated voltage pre- starting the arc facility it
Between distance.The design of the pre- arc starter is favourable, because by the electric arc shape in two regions of main contacts
Into corresponding loss only occur on the pre- starting the arc facility specified for this.
According to earthed switch of the invention it is other preferred embodiment in, pre- starting the arc facility construction is the pre- starting the arc
Angle.This is favourable, because play arc angle in advance and being only short circuit making design and constructing.With this, the pre- arc angle that rises is the load to work
Lotus optimally constructs and use that is being particluarly suitable on earthed switch.
According to the preferred improved design project of aforementioned embodiments, arc angle is played in advance substantially by horizontal oriented arrangement and
Accordingly arranged with each main contacts.This has advantage, because the electric arc for producing by this way is only in the pre- region for playing arc angle
Middle generation.
According to the further preferred embodiment of earthed switch of the invention, pre- starting the arc facility construction is trick arc
Angle.
This has advantage, because by making in the disconnect switch should simultaneously with breaking current ability to bear higher
It is very early known and by proving with middle arcing horn.When short circuit making stability is also required that for load break switch
The use of arcing horn is especially significant.Playing arc angle in advance in the comparison can not provide breaking current ability to bear higher so that
This implementation method is particularly suitable for the earthed switch with extra high short-circuit stability.
Arcing horn is substantially along vertical oriented arrangement in the other implementation method according to earthed switch of the invention
And accordingly arranged with each main contacts.This has advantage, because thus electric arc produce only in the region of arcing horn.The electric arc
Because hot floating effect is driven along arcing horn upwards and finally reaches the end of the regulation for loss of arcing horn.
According to the further preferred embodiment of earthed switch of the invention, earthed switch is suitable for repeatedly carrying out
Short circuit making.Born once or multiple short circuit making according to earthed switch of the invention, this is relative to known ground connection
The advantage of switch, it is known that earthed switch can be typically damaged due to short circuit making.Therefore, it is according to earthed switch of the invention
Especially need not often safeguard and it is anti-short circuit.
According to earthed switch of the invention it is further preferred embodiment in, the closing speed choosing of earthed switch
It is selected as, before the main contacts self-contact of earthed switch, matches somebody with somebody by corresponding with the earthed switch in electric railway power supply network
If breaker be capable of identify that and disconnect the short circuit formed by electric arc on the pre- arc starter.It is so-called to use
High-speed switch substitute breaker.
The effect is that breaker by being present in electric traction power supply network can be recognized and (produced such as on pre- arc starter
Occur during raw electric arc) short circuit realization.Breaker then can correspondingly interrupt short circuit so that just extinguish when main contacts is closed
Electric arc and make main contacts no current.When breaker and special high-speed switch generally can make protection triggered time and switch off current
Between be maintained at typically less than 100ms.The current loading of the main contacts of earthed switch therefore only can be in the breaker break-make of power supply
Occur in the case of failure.If the break-make failure of breaker, back-up protection just plays a role.Generally this leads in transformer station
Cause to trigger breaker in input side.Although its pull-up time is only 20ms, when can be by other treatment or synchronization
Between extend total current pass through duration.The mistake is for being impossible event by the short circuit making of earthed switch
It is considered to have very small possibility and is had little to no effect in day-to-day operation.
In DC voltage field for be greater than 20kA short circuit current high turn-off time in 20ms to 30ms
In the range of.Generally, electric current is even turned off within less than 20ms.
Even if described in people being in the flat of 40ms for rapidly switching off for short circuit current high in the alternating voltage field
Turn-off time in the case of equal break time in the range of 20ms to 60ms.
The turn-off time of the breaker of power supply also increases in addition to relevant with current amplitude itself with the sense of current, electric current
Impedance loop with measurement is relevant.But these extra measured value Processing Algorithms are effective only for lower amplitude.With this not
With ground, the short circuit with higher amplitude can cause bigger infringement.The purpose of impedance measurement is even for smaller short circuit electricity
The situation of the dissimilarity of stream and high workload electric current also can reliably short detection in the switch module of whole subordinate.The impedance
, generally with the time delay between 20ms and 30ms, (20ms is extremely short circuit current duration is reached to maximum 100ms for level
60ms+30ms)。
By the aforementioned estimation that turn-off time of the breaker less than 100ms is drawn in the simple estimation.
Therefore, earthed switch is configured in this embodiment, and in contrast its closing speed is so slow so that
Corresponding electric arc safely passes through circuit breaker trip before main contacts closure.Preferably, main contacts is closed at about
Realized after 200ms to 250ms.Therefore for the implementation method it is important that according to earthed switch of the invention characteristic with it is logical
The combination of the characteristic of normal breaker.
With this, by easy structural design scheme relative to connecing so far according to earthed switch of the invention
Ground switch is realized for the simple and inexpensive solution using the earthed switch with short circuit making.The design
Additional advantage is that can simply be installed from drive device because especially do not need earthed switch based on
The instant shut-in function of spring energy-storage drive device, to accelerate the closing course of main contacts and with this to reduce the electric arc by occurring
The load for causing.
According to the further preferred embodiment of earthed switch of the invention, pre- arc starter has can be detachable
The burnup element that ground is installed.
So there is advantage, because burnup element may be mounted on pre- arc starter and can easily change, and
The corresponding arcing horn of pre- arc starter need not be changed.Thus not only in the manufacture of burnup element but also in pre- arc starter
Maintenance in reduce cost because must only change burnup element now.
Additional advantage is, the recalibration of whole pre- arc starter need not be carried out when burnup element is changed, this
Time and cost are saved in maintenance.Again improve the Technical Availability of trolley wire system.
In the preferred improved design project of aforementioned embodiments, burnup element has internal thread and can be according to bolt
The mode of connection is arranged on pre- arc starter.The bolted advantage is on the one hand to ensure burnup element by screwing
Long-term safety it is locked on pre- arc starter, on the other hand can easily changes burnup element.
According to earthed switch of the invention it is other preferred embodiment in, it is short according to expected from earthed switch
The length that frequency ground determines burnup element is connected on road.This has advantage, because can in advance risen depending on client or project
Requirement in terms of the time-on in percent of arc device selects the burnup element of appropriate length, even if also in burnup element high load capacity
Default maintenance period is kept without additional maintenance.
According to earthed switch of the invention it is other preferred embodiment in, burnup element includes more as material
Dissipate the copper product of reinforcing.This has advantage, because the shut-off of operating current can so optimized.By the copper of dispersion-strengtherning
The burnup element of material manufacture has the temperature tolerance higher relative to fine copper and with this electric arc tolerance higher, and this makes pre-
Arc starter has the availability of longer time in the case of without consuming is safeguarded.Additional advantage is, by dispersion-strengtherning
The burnup element of copper product manufacture is compared to the known tip manufactured by tungsten in addition in purchase substantially more honest and cleaner in price
Valency.
