Sincé few days every time I Open Outlook 2016 It says that the file xxxx.pst is corrupted, and it ask me to repair it. I say yes, It opens a new program "Microsoft Outlook Inbox repair tool" and it proced to first make a backup copy and then to repair it. Then I can open Outlook, but afer some time 30 min, 1 hour... Outlook closes and say again the xxx.pst is corrupted.

My Ost file is 3 GB large, is it too much? could be it the problem? How to reduce it?

That is a normal size.  
When you use Outlook, the following .ost size guidelines generally apply:  
Up to 5 gigabytes (GB): This file size should provide a good user experience on most hardware.

Just to be on the safe side, create a new Outlook profile and see how it behaves. If you are still facing the same issue, run Outlook in safe mode (either hold the CTRL key while launching it or type 'Outlook /safe' in the run box), see if the issue remains. In addition, disable any AV and other types of scanning software (malware scans, backup scans, etc).

It seems like your PST file is severely corrupted. I suggest you, repair your PST file with Inbox Repair Tool until it shows no error. In case if that does not work for you then you can go for a third party tool like Stellar Phoenix Outlook PST Repair software.

You can get software's demo version from here: https://www.stellarinfo.com/outlook-pst-file-recovery.php

I'm using the scanpst.exe to try to repair the ost files.
After it, it says "It has been repaired" But if I try to repari again it says that it must be repaired.
Here is the log after repairing:
