Abstract
The present invention relates to the close-coupled breaker with multiple contacts.Breaker includes one group of contact with one or more contacts and the other groups of contacts with one or more contacts, wherein, one group of contact is angularly installed on the other groups of contacts.
Description
Technical field
The present invention relates to breaker, and more specifically it relates to the close-coupled breaker with contact, contact is relative to disconnected
The axis of road device electrode is at an angle of.
Background technology
In power system, breaker plays indispensable effect.Breaker holding circuit is not overloaded or short circuit is drawn
The damage risen.This is completed by detecting fault state and disconnecting circuit with interruptive current.
When a circuit is open, the electric current in circuit often produces temperature very high electric arc.Such electric arc may
Damage circuit.In order to solve this problem, breaker is by itself will be connected on circuit and force electric current to flow to wherein to come
Disconnecting circuit.In this case, electric arc is produced in the inside of breaker, wherein, breaker can extinguish electric arc, and not have to circuit
There is any infringement.Breaker is connected on circuit using its contact arm, and contact arm has the contact installed in the end of contact arm.
In the traditional design of breaker, contact arm length and parallel to each other.Because contact arm is long, breaker takes larger area
Space.Additionally, due to brachium, the cost of material is also high.It is longer that long contact arm also results in current flow path, this can cause power attenuation and
Excessive materials'use.Due to the parallel arrangement of contact arm, contact arm can undergo electromagnetic force, so as to cause structural weak points.
Therefore close-coupled breaker a kind of cost-effective and with improved structural strength is needed.
Subject invention
It is an object of the present invention to provide a kind of close-coupled breaker.
It is also an object of the present invention to provide a kind of cost-effective close-coupled breaker.
It is also an object of the present invention to provide a kind of close-coupled breaker with improved structural strength.
A further object of the present invention is to provide a kind of close-coupled breaker being easily assembled to.
It is also an object of the present invention to provide a kind of close-coupled breaker with shorter current path.
The content of the invention
The present invention provides a kind of breaker with multiple contacts, wherein, breaker includes one group of contact and other groups are touched
Head.One group of contact in multiple contacts has one or more contacts, and is angularly installed in multiple contacts
On the other groups of contacts.The other groups of contacts have one or more contacts.
The present invention also provides a kind of switching device of the breaker including the present invention, wherein, one group of contact can be electrically connected
It is connected on corresponding group of contact of bus, or may be electrically connected on corresponding group of contact of current transformer.The present invention is also carried
For the similar switching device of the breaker using the present invention, wherein, the other groups of contacts may be electrically connected to the corresponding of bus
On the contact of group, or it may be electrically connected on corresponding group of contact of current transformer.
Brief description of the drawings
Fig. 1 is the schematic diagram of the conventional circuit breaker according to prior art.
Fig. 2 is the schematic diagram of the breaker according to the present invention.
Embodiment
The present invention relates to a kind of close-coupled breaker, its is cost-effective and with improved structural strength.Using exemplary
Embodiment illustrates the present invention, and the present invention is not limited.
Fig. 1 shows the conventional circuit breaker 100 according to prior art.Breaker 100 is made up of lower person：Breaker electrode 110,
Two contact arms 120 and 130 on breaker electrode 110 and two Hes of contact 125 being located at respectively on contact arm 120 and 130
135.When breaker 100 works, breaker electrode 110 is flatly moved towards the contact of circuit.This causes breaker 100
Contact 125 and 135 contacts the contact of circuit, disconnecting circuit and forces electric current to flow in breaker 100, and breaker 100 can be located
The electric arc that reason is interrupted and produced in electric current stream.
As seen from breaker 100, the length of the size of breaker directly to contact arm is proportional.Therefore with length
The conventional circuit breaker of contact arm takes more space.In addition, when the contact arm of breaker is long, the cost of material is also high.Long contact arm is also
Longer current flow path can be produced, this can cause power attenuation and excessive materials'use.In addition, in conventional circuit breaker, touching
Arm is parallel to each other, and this causes when electric current flows through them, contact arm experience electromagnetic force.These electromagnetic forces can weaken electrode and be located therein
Housing structural intergrity.
The present invention overcomes all these problems by changing breaker.Fig. 2 shows the breaker according to the present invention
200.Breaker 200 includes breaker electrode 210, the contact 230 and 220, Yi Jiyi being directly installed on breaker electrode 210
Dynamic component.Contact 220 and 230 is arranged on breaker electrode 210 so that contact is at an angle to each other.In the exemplary embodiment
In, contact is positioned to perpendicular to one another.The breaker 200 of the present invention has to the mobile moving assembly of itself.In the example
Property embodiment in, this moving assembly is by pushing (racking) screw rod 250, dipper crowding gear 260, and one with wheel 240
Body framework is shown.By making pushing screw rod 250 clockwise or counterclockwise, operator may move breaker 200.In startup
Afterwards, contact of the breaker 200 flatly towards circuit is moved.The contact corresponding with circuit of contact 220 and 230 is engaged.This causes
Circuit disconnects, and forces electric current to flow in breaker 200, and breaker 200 can suitably handle the electric arc that electric current is produced.Contact 230
Include tulip shape contact or slidably contact with 220.
This novel and creative structure of breaker causes breaker more compact.And by eliminating breaker
Contact arm, the cost of material is also reduced, and the cost efficiency of breaker is improved.Due to there is less component, assembling process is obtained
Simplify.Which also reduces the possibility of mistake assembling.By reducing the size of breaker and eliminating the contact arm of breaker, transmission electricity
Also reduce in the path of stream.This is favorably improved efficiency, reduces power attenuation, increase thermal life and reduction materials'use.And it is logical
Crossing makes contact keep angled each other, and the magnetic force acted on contact of generation also reduces.This causes the housing of breaker electrode
Structural strength improved.
Therefore the present invention provides a kind of close-coupled breaker, and its is cost-effective, it is easy to assemble, with improved structural strength
Shorter current path.
