Abstract
The utility model discloses a kind of super-large current three-phase reactors, belong to reactor technical field, and the super-large current three-phase reactor includes iron core, coil and fixed structure piece；It is characterized by: iron core is horizontal day word iron core；The coil is divided into three groups, is successively named as A phase coil, B phase coil and C phase coil；Every phase coil is made of multiple sub-coils, and each sub-coil is formed by a conducting wire coiling；A main goddess of lightning row is respectively arranged in the two sides of every phase coil；The leading-out terminal of each sub-coil is electrically connected with the main goddess of lightning of two sides row respectively；There are air insulation clearances between adjacent two phase coil.By using above-mentioned technical proposal, the utility model converges the electric current of multiple sub-coils on main goddess of lightning row, it can be increased the electric current of three-phase reactor in this way, and then meet the output of super-large current, simultaneously, since each sub-coil is only formed by a conducting wire coiling, the requirement of high-voltage isulation ensure that.
Description
Technical field
The utility model belongs to reactor technical field more particularly to a kind of super-large current three-phase reactor.
Background technique
Reactor is also inductor, when a conductor is powered will the certain space range occupied by it generate magnetic field,
So the electric conductor of all energy current-carrying has perception in general sense.However the inductance for the long straight conductor that is powered is smaller, it is produced
Magnetic field it is not strong, therefore actual reactor is that conducting wire is coiled into helical form of tubes, claims air reactor；Sometimes for allowing this spiral shell
Spool has bigger inductance, and iron core is just inserted into solenoid, claims iron core reactor.Reactance is divided into induction reactance and capacitive reactance, compares
The classification of science is that impedor (inductor) and capacitive reactance device (capacitor) are referred to as reactor, however since first there is inductance in the past
Device, and referred to as reactor, so capacitor described in people is exactly capacitive reactance device now, and reactor refers exclusively to inductor.
Currently, the current range of conventional three-phase reactor is 1000A-1200, but in some Code in Hazardous Special Locations, need bigger
The three-phase reactor of electric current, more high current, traditional technical solution are that the progress of multiple three-phase reactors is in parallel in order to obtain, but
It is obviously that the defect of this technical solution is: volume is big, and carries inconvenience, therefore designs and develops a kind of more practical surpass
It is particularly important that high current three-phase reactor, which seems,.
Utility model content
In view of the drawbacks of the prior art, the utility model provides a kind of super-large current three-phase reactor, so that three-phase reactor
Device exports super-large current, while meeting the requirement of insulation and heat dissipation.
Used by the utility model the specific technical proposal is:
The goal of the invention of this patent is to provide a kind of super-large current three-phase reactor, and the super-large current range is 4000A-
4500A, the super-large current three-phase reactor include iron core (2), coil and fixed structure piece (5)；
The iron core (2) is horizontal day word iron core；The coil is divided into three groups, is successively named as A phase coil, B phase coil
With C phase coil；Every phase coil is made of multiple sub-coils (4), and each sub-coil (4) You Yigen conducting wire coiling forms；
A main goddess of lightning, which is respectively arranged with, in the two sides of every phase coil arranges (1)；The leading-out terminal of each sub-coil (4) is distinguished
(1) is arranged with the main goddess of lightning of two sides to be electrically connected；
There are air insulation clearances between adjacent two phase coil.
The advantages of the utility model and good effect are as follows:
By using above-mentioned technical proposal, the utility model is had the following technical effect that:
By using above-mentioned technical proposal, the utility model by the electric currents of multiple sub-coils confluence on main goddess of lightning row, this
Sample can be increased the electric current of three-phase reactor, and then meet the output of super-large current, simultaneously as each sub-coil is only by one
Conducting wire coiling forms, therefore ensure that the requirement of high-voltage isulation, exhausted since there are air between two phase coil adjacent in this patent
Intermarginal gap, therefore under the premise of guaranteeing insulating requirements, the purpose of rapid cooling is realized, when enabling three-phase reactor long
Between continuous work.
Detailed description of the invention
Fig. 1 is the structure chart of utility model preferred embodiment；
Wherein: 1, main goddess of lightning row；2, iron core；3, coil；4, sub-coil；5, fixed structure piece.
Specific embodiment
For the invention, features and effects that can further appreciate that the utility model, the following examples are hereby given, and cooperates
Detailed description are as follows for attached drawing.
The structure of the utility model is explained in detail with reference to the accompanying drawing.
Please refer to Fig. 1: a kind of super-large current three-phase reactor, the super-large current range is 4000A-4500A, described super
High current three-phase reactor includes iron core 2, coil 3 and fixed structure piece 5；Iron core 2 is connected by fastener and fixed structure piece 5
It connects；
The iron core 2 is horizontal day word iron core, i.e., by traditional day word iron core rotated ninety degrees, in structure of droping to the ground；The line
Circle is divided into three groups, is successively named as A phase coil, B phase coil and C phase coil；Every phase coil is made of multiple sub-coils 4, each
Sub-coil 4 is formed by a conducting wire coiling；
A main goddess of lightning row 1 is respectively arranged in the two sides of every phase coil；The leading-out terminal of each sub-coil 4 is respectively with two
1 electrical connection of main goddess of lightning row of side；
There are air insulation clearances between adjacent two phase coil.
Utility model works principle: the utility model by the electric currents of multiple sub-coils confluence on main goddess of lightning row, in this way
It can be increased the electric current of three-phase reactor, and then meet the output of super-large current, simultaneously as each sub-coil is only led by one
Line coiling forms, therefore ensure that the requirement of high-voltage isulation, since there are air insulations between two phase coil adjacent in this patent
Gap, therefore under the premise of guaranteeing insulating requirements, realizes the purpose of rapid cooling, enable three-phase reactor for a long time
Continuous work.
The above is only the preferred embodiment to the utility model, is not made in any form to the utility model
Limitation, it is all according to the technical essence of the utility model any simple modification made to the above embodiment, equivalent variations with
Modification, is all within the scope of the technical scheme of the utility model.
