Description
Technical field
The present invention relates to the switchgear of electric mechanical, and it has a switch contact for being used to interrupt electric wiring, and
One, which is used for extinguishing, is leading to the electric-arc distinguishing device of electric arc caused by the switch contact disconnection of electricity.The concept of switchgear is herein
Protection switch equipment, such as power switch, line protection switch or fault current switch are not only interpreted as, also is understood as not having
Switchgear, such as on-load switch, disconnecting switch or the load-break switch of the defencive function of itself.
Background technology
Different types of protection switch equipment is there is known from the prior art：Power switch is designated specifically to high electricity
Stream.Line protection switch（So-called LS switches）It is a kind of overcurrent protection used in electric installation and particularly
Used in the field of secondary network.Power switch and line protection switch ensure that the reliable cut-out in short circuit and prevent
Only customer and electric system overload, such as prevent electric line by too strong heating caused by too high electric current and impaired.
They are configured to, automatically cut off in case of a short circuit or in the case where occurring overloading the circuit that need to monitor and therefore and its
Remaining circuit network separates.Therefore power switch and line protection switch are particularly useful as switch and safety element, for monitoring and
Protect the circuit in the energy supply network of electricity.
The person, property or fireproof protection can be also realized by means of failure current protection switch.Therefore, it is related to and opens as follows
Close equipment, its broken down in the equipment and system of electricity in the case of by the equipment and system in most short time internal cutting off,
And when electric current " mistake path on ", for example through personnel's body towards the earth flow when, by the equipment and system and its
Remaining power network separates.Therefore, failure current protection switch by the current strength of the electric current flowed towards electric consumption device with disappearing from described
The intensity of the electric current of consumption device backflow is compared.Corresponding failure current protection switch is for example from publication EP 0 957 558
It is known in A2.
In addition, the switchgear without the defencive function of itself is it is also known to from the prior art.The example fallen under it
So-called on-load switch, disconnecting switch or load-break switch in this way.Load-break switch is interpreted as following switchgear, its
Not only meet the requirement for on-load switch, the i.e. switch under electric load in terms of its feature, and meet for every
Pass proposed requirement is left, i.e., isolates electric system part approximate inactivity.Load-break switch is suitable for cutting off big electricity
Stream, its certain switching capability are typically smaller than the switching capability of power switch.In secondary network, load-break switch for example for
The main circuit in main distribution region is interrupted, wherein, power switched is usually located in 40 and 63kA scope.According to DIN EN
60947-3, not only classified by load-break switch but also by on-load switch and disconnecting switch according to their own power capability
Into so-called consumption classification, in the consumption classification, according to the difference of applicable cases, different requirements is defined.
In general, switchgear is mostly conductive even via the electric wiring of two binding posts and the circuit that need to be monitored
Connect, to interrupt the electric current in each circuit when needed.Therefore, the switchgear has a switch contact, the switch touches
Point with one fix contact element, so-called fixed contact, and one relative to the movable contact element of the fixed contact,
So-called motion contact.In order to turn on an electric current, fixed contact described in the motion contact.In order to separate the electric current,
The motion contact is removed from the fixed contact.The motion contact can for example be set via the switch in the case
Standby switching mechanism is operated, so as to disconnect and close the switch contact.In the situation of protection switch equipment
Under, the switch contact can be disconnected by this way in the case where predefined state, such as short circuit or overload occur,
The circuit of monitoring and electric wiring network to be separated.This switchgear also serves as series connection peace in the field of low-voltage technology
Install standby（Reiheneinbaugeräte）It is known.
The electric current is interrupted by disconnecting the switch contact, in the case, at least result in short time solid
Voltage breakdown between fixed contact element and the contact element of motion, because being used during the separation process of the contact element
In insulation distance not enough.If having gas between described two switch contacts, it is between the contact element
Corresponding high voltage difference in the case of by it is described breakdown be ionized, wherein, an electric arc is constructed due to gas discharge.
In order to extinguish the electric arc, traditional switchgear has an electric-arc distinguishing device, such as so-called extinguishing room, and it has a large amount of
Arc extinguishing board be arranged side by side and spaced.As an alternative, the electric-arc distinguishing device can also be only by multiple, mutually flat
The arc extinguishing board or coldplate of row orientation are formed.If the electric arc is driven towards the electric-arc distinguishing device, it is being met
Multiple points of electric arcs are divided into during to the arc extinguishing board, it is described to divide electric arc then to be burnt in series between single arc extinguishing board.
The multiple, electric ground sequential series to divide electric arc generally to result in higher arc voltage, this result in the electric arc more again
Fast extinguishing.
In order to which a Lorentz force is applied on the electric arc and extinguishes the electric arc as quickly as possible, for
Direct current（DC-）Usually using additional permanent magnet in the case of the switchgear of application.By the use of permanent magnet, can realize
Compare high magnetic field intensity, but the magnetic field as caused by permanent magnet is constant in time in terms of its direction, therefore installing
During permanent magnet it is noted that towards each sense of current correct magnetic pole, to obtain the electric arc along desired direction.Handing over
Stream（AC-）It is generally uncomfortable due to the alternate polarity that continues of the arc current, therefore in switchgear in the case of
Electric arc is influenceed with permanent magnet.
It is provided for the switchgear of AC network therefore usually there is so-called arc blow-out loop（Blasschleife）, use
So that electric arc to be removed from switch contact as quickly as possible.Arc blow-out loop is a kind of electric coil, and it is arranged in switch contact
Extraly it is powered in region and in the case of by disconnecting the switch contact the electric arc that occurs.Alternative in this, institute
Arc blow-out loop is stated can also to be enduringly powered.As the electromagnetic field caused by having led to the arc blow-out loop of electricity in the case with as follows
Mode is orientated so that a Lorentz force is applied on the electric arc, and the Lorentz force is by electric arc from the switch contact away from simultaneously
Extruded towards the electric-arc distinguishing device.Corresponding switchgear is from the B1 of publication DE 2 841 004 or from publication DE 3
It is known in 333 792 A1.But the shortcomings that arc blow-out loop is, small electromagnetic field is only produced in the case of the electric current of very little, from
And thus the caused electromagnetic force being applied on electric arc is smaller.Therefore it could only send out in the case of big electric current
Its complete effect is waved, such as in the case of short circuit.
The content of the invention
Therefore the task of the present invention is, there is provided a kind of switchgear of the electric mechanical with an electric-arc distinguishing device,
It is characterized in that rapidly and reliably extinguishing the electric arc occurred when the switch contact for having led to electricity disconnects, and it is possible
Service condition in terms of high changeability.
The task solves by the switchgear of the electric mechanical according to the present invention according to independent claims 1.Favorably
Design be dependent claims theme.
One switch contact for being used to interrupt electric wiring, Yi Jiyi are had according to the switchgear of the electric mechanical of the present invention
Leading to the electric-arc distinguishing device of electric arc caused by the switch contact disconnection of electricity for extinguishing.The electric-arc distinguishing device is herein
In the case of there is the first permanent magnet and the second permanent magnet, they are arranged opposed to each other in the both sides of the switch contact and phase
Mutually oppositely it is magnetized, mode is that they are mutually pushed open.
The concept of switchgear is not only interpreted as protection switch equipment herein, and is interpreted as not having the protection work(of itself
The switchgear of energy.For example consider power switch, line protection switch or failure current protection switch as protection switch equipment.
Falling into the switchgear without the defencive function of itself for example has on-load switch, disconnecting switch or load to keep apart
Close.Utilize a kind of mechanically operable of representation of concept of " switch contact ", electrical contact element pair, its have a fixed contact and
One relative to the movable motion contact of the fixed contact.Fixed contact and motion contact are arranged in so-called in the housing
In the region of switch gear room.By mechanically operating the motion contact, the switch contact of closure can be disconnected, thus interrupt warp
Cross the electric current of the switch contact.
First permanent magnet and second permanent magnet are in the both sides of the switch contact, that is to say, that are opened described
The left side and the right for closing room are arranged opposed to each other.Their oppositely mutually magnetization in the case, mode is that described first forever
The magnetic vector of magnet and the magnetic vector of second permanent magnet are mutually oppositely orientated.Such as the magnetic of first permanent magnet
Property the South Pole and the magnetic south of second permanent magnet be respectively facing the switch gear room and point to；Replace or described
The magnetic north of first permanent magnet and the magnetic north of second permanent magnet are respectively facing the switch gear room and pointed to.In two kinds of feelings
Under condition, described two permanent magnets are mutually pushed open.
One magnetic field is produced by first permanent magnet and second permanent magnet, the magnetic field in the switch for having led to electricity with touching
The magnetic field for the electric arc that point occurs when disconnecting is overlapping.One electromagnetic force, so-called Lorentz force are applied to by resulting magnetic field again
On the electric arc.The Lorentz force represents a kind of power in the case, and it is applied to the electric charge of a motion, here by a magnetic field
On the electric arc.The force vector of the Lorentz force depends primarily on the polarity of the electric current in the case, that is to say, that takes
Certainly in the sense of current by the electric arc.But it is unrelated with the polarity of the electric current, and therefore with passing through the switch contact stream
Dynamic be either direction direct current or alternating current it is unrelated, the force vector has all the time due to overlappingly caused magnetic field
One durection component, direction component squeeze the electric arc from the switch contact.Which results in the lengthening of the electric arc, and it is again
It result in higher arc voltage.If the arc voltage is excessive, the arc extinction and disappearance.
Electric arc quick occurred when the switch contact for having led to electricity disconnects is realized by this way and is reliably put out
Go out.The extinguishing power of the electric-arc distinguishing device and therefore thus the switch power of the switchgear is increased significantly.It is special
It is not that thus, it is possible to realize, otherwise ability is real only in the case of identical device structure in the case of load-break switch
It is existing to the classification in higher consumption classification.In addition, the electric-arc distinguishing device and being designed with the electric-arc distinguishing device
Switchgear be used not only for direct current（DC）Using also can be used in exchanging（DC-）Using.A such as pin by this way
Load-break switch that is set to AC applications and being therefore classified into AC consumption classifications also meets DC lower if necessary
The requirement of classification is consumed, therefore it can equally be classified for the category.Due to resulting in involved switch

Arc, it is described to be divided to electric arc to be burnt respectively between two arc extinguishing boards.Electrically coupled in series electric arc is divided to considerably improve arc by substantial amounts of
Voltage, which results in the quick extinguishing of the electric arc.
One magnetic field is produced by first permanent magnet and second permanent magnet, the magnetic field in the switch for having led to electricity with touching
The magnetic field for the electric arc that point occurs when disconnecting is overlapping.By producing an electromagnetism being applied on the electric arc from resulting magnetic field
Power, so-called Lorentz force.Its force vector depends primarily on the polarity of electric current in the case.But the force vector is not passed through
The influence of the polarity of the electric current of the electric arc flowing has a durection component all the time, and direction component opens the electric arc from described
Contact is closed to leave and extrude towards the electric-arc distinguishing device.By the electric-arc distinguishing device the switchgear housing
