1、变压器的铁心是片与片绝缘叠装的；
1. The core of the transformer is overlapped with the sheet insulation.
2、主要是减小涡流及其损耗；
2. The main purpose is to reduce eddy current and its loss.
片与片绝缘叠装，怎么减小涡流及其损耗？
How to reduce eddy current and its loss when laminated with laminated insulation?
1、如果铁心是一整块金属铁，当其内部有交变磁通时，就会有漩涡状的感生电流，使铁心很快发热熔化；
1. If the core is a whole piece of metal iron, when there is alternating magnetic flux in it, there will be eddy-like induced current, which makes the core heated and melted quickly.
2、片与片绝缘叠装，就等于切断了涡流的回路，或者说断开了涡流的电路，这样不就减小了涡流；
2. Insulating and overlapping the wafer and the wafer is equivalent to cutting off the circuit of the eddy current, or disconnecting the circuit of the eddy current, which will not reduce the eddy current.
3、如果你两点接地，就等于把片与片绝缘叠装切断的涡流电路给接通了，就会通过地在两点形成涡流回路，产生涡流；
3. If you are grounded at two points, it is equivalent to switching on the eddy current circuit which is fangdaomen.89ix.comdiankonggui.89ix.com tiepuyi.89ix.comtanceqi.07858.net bianyaqiyj.37ix.com.cngangguanh.37ix.com.cncut off by overlapping the insulation between the sheet and the sheet. It will form the eddy current circuit at two points and generate the eddy current.
4、所以两点接地，会使铁心片之间短路，产生涡流，使铁心发热！
4. Therefore, the two-point grounding will make the core short-circuit between the sheets, generate eddy current, make the core hot!
