I just dowloaded Electrum and made some test transfers to it from Blockchain. According to them fee was enough to get confirmation within 20 minutes. But now after three hours in history I see one transaction with Unconfirmed status and others with Unconfirmed parent status. What does it mean and what's the difference? And why it takes so long to confirm the transaction?

Unconfirmed status - The transaction doesn't have any confirmation, or in other words hasn't been validated yet (funds aren't secure)
Unconfirmed parent status - The transaction is using funds from another transaction that doesn't have any confirmation yet (like above)

Tried to explain with easy words, hope you get the picture.

And why it takes so long to confirm the transaction?
It depends to the following reasons:

1. Low fee being used
2. Unconfirmed parent
3. No blocks being found within an hour or more (it happens sometimes, although a bit rare)

Thanks, it quite a plain explanation.
Just have another question to clarify.
I bought some test amount of bitcoins in my Blockchain wallet today via Visa card. And then transfered part of it to my Electrum wallet. Then, as I understand, the parent transaction for this transfer is buying bitcoins on Blockchain with my Visa card? So why is it regarded as not confirmed yet? It is not bitcoins to bitcoins transfer, which needs miners confirmation, it just kind of ordinary card operation, and my balance on Blockchain was loaded immediately. So why it has status of Unconfirmed?

You're welcome.

Correct (assuming you don't have any other unconfirmed transactions).

So why is it regarded as not confirmed yet? It is not bitcoins to bitcoins transfer, which needs miners confirmation, it just kind of ordinary card operation, and my balance on Blockchain was loaded immediately. So why it has status of Unconfirmed?
When you purchased some test amounts through your visa card, they sent it (the bitcoin amount) to you through their own bitcoin address, in which makes it a bitcoin to bitcoin transfer, therefor it needs a confirmation before you could normally use it. Balances will always get updated instantly on blockchain but you could only use it when it has a confirmation.

Read the following thread for ways to help you sort the confirmation issue: https://bitcointalk.org/index.php?topic=1802212.0
Easiest solution is to use the ViaBTC accelerator (as long as the fee is good enough): https://www.viabtc.com/tools/txaccelerator/
