I reckon this is an auto-transformer as there are only three wires.

我估计这是一个自动变压器,因为只有三根电线。

0v bottom, 底部
110v tap, 龙头
230v top, 最佳

So, no primary-secondary isolation.

所以,没有主要 - 次要隔离。

Here are two (un related) circuits....the one on the left using an Auto-Transformer and the one on the right using a normal (full isolation) transformer.

这里有两个(不相关的)电路......左边的电路使用自耦变压器,右边的电路使用普通(完全隔离)变压器。

I linked them just to show the difference between auto and normal transformers.

我把它们联系起来只是为了显示自动和普通变压器之间的区别。

我确定它是隔离变压器,我测量过,一次侧和二次侧不相通。

我不会英文,所以我用中文,请你们用翻译网站翻译我打的字!

I can't in English, so I in Chinese, please use the translation website to translate my words!

Translation of the above...."I am sure it is an isolation transformer, I measured it, the primary side and the secondary side are not connected."

Why are there only three wires? 为什么只有三根电线?

Is a fourth wire hidden from the camera somewhere? 是否有第四根电线隐藏在相机的某处?

一次侧220V是两条红线,你可以在另一张图看到!
