Abstract
Disclosed is a current sharing apparatus for a current transformer, comprising a support, wherein the support is provided with a current transformer unit thereon; the current transformer unit comprises a power module; the power module is provided with an insulated gate bipolar transistor output terminal; and the support is provided with an external copper bar. The technical scheme of the utility model is characterized in that: the external copper bar is associated with the output terminal via a connecting cable. The utility model aims at overcoming the defects of the prior art and providing a current transformer current sharing apparatus featuring simple structure, low cost, and convenient usage.
Description
[technical field]
The present invention relates to a kind of current transformer, a kind of current transformer current equalizer of more specifically saying so.
[background technology]
Between the lead-out terminal of the power model of existing wind-driven generator current transformer and the outside copper bar all is to be connected through copper bar; Be exactly insulated gate bipolar transistor IGBT output basically all be to adopt copper bar to connect; It is uneven to cause electric current to distribute like this; It is inconsistent the IGBT internal components life-span to occur, and the device of certain point may just damage at short notice.
[summary of the invention]
The present invention seeks to overcome the deficiency of prior art, provide a kind of simple in structure, cost is low, current transformer current equalizer easy to use.
The present invention realizes through following technical scheme:
The current transformer current equalizer; Comprise support 1; Described support 1 is provided with converter cell 20, and described converter cell 20 comprises power model 2, and described power model 2 is provided with insulated gate bipolar transistor lead-out terminal 3; Described support 1 is provided with outside copper bar 4, it is characterized in that: be connected by stube cable 5 between described outside copper bar 4 and the described lead-out terminal 3.
Aforesaid current transformer current equalizer is characterized in that: each described power model 2 is provided with 4 described lead-out terminals 3, and each described lead-out terminal 3 is connected with described outside copper bar 4 by a described stube cable 5.
Aforesaid current transformer current equalizer is characterized in that: described support 1 is provided with a plurality of spacer for hangers 6, and each described spacer for hanger 6 is provided with one group of described converter cell 20.
Aforesaid current transformer current equalizer is characterized in that: described spacer for hanger 6 is 4.
Compared with prior art, the present invention has following advantage:
1, the present invention adopts cable to connect power model and outside copper bar, and it is inconsistent to have avoided electric current to distribute inequality the IGBT internal components life-span can occur, makes whole current transformer physical life lengthening.
2, the present invention is simple in structure, and cost is low, and is easy to use.
[description of drawings]
Fig. 1 is a structural representation of the present invention;
Fig. 2 is a structural representation of the present invention.
[embodiment]
The current transformer current equalizer; Comprise support 1; Described support 1 is provided with converter cell 20, and described converter cell 20 comprises power model 2, and described power model 2 is provided with insulated gate bipolar transistor lead-out terminal 3; Described support 1 is provided with outside copper bar 4, is connected by stube cable 5 between described outside copper bar 4 and the described lead-out terminal 3.
