Maybe its a Dendrobium Phalaenopsis of some type. Try to google images of this and you will see it is very similar to your orchid. They look like a Den. Nobile however their leaves are not flexible.

I have the same Pychopsis orchid as you and they are just so fascinating. Remember not to cut the spike it is a sequential bloomer and will rebloom on the same spike around a month after the first flower has dropped. I have watched a nursery grower on the internet and he said they can rebloom on the same flower spike for up 12 years.
