Hi @Alyona11, sorry to hear about this. 
I have translated your question to English as this is an International forum, please post any replies in English and it will be easier for me and other users to assist you.
Are you doing anything specific in the device when it's restarting, for example using a certain application or service? A defect SIM or SD card can cause the device to restart, so try and temporarily remove them and see if that helps.
Should there be no change, restart your device in safe mode so we can see if any of your downloaded applications are the cause of these restarts that you are having as downloaded applications are temporarily disabled in this mode.
Let me know how it goes!
