I use format [[HH]:MM for time. Then hour can be maximum 2 digit number ( from 0 to 24 ). Is it possible for calc to add sign : after every second number ? Or : is it possible for calc to use sign : when I press key ./del on numerical keypad ?

Not as far as I know. Times are stored as numbers - as fractions of a day - so any number you enter, even if it contains a point, is interpreted as a number of days but then displayed in hours and minutes, as you have chosen. Critically, it is the presence of the colon that would indicate that you are entering a time in hours and minutes, and I don't see how you can stimulate that interpretation without it.

The simplest workaround might be to enter just the digits of the time - always including the units digit of minutes - into a column (let's say column A) formatted as number. Then, in another column (say B), you could calculate the required value in the appropriate formula. In B1, enter:
Fill this down column B and format the column as a time as you require.

If you prefer, you could format column A as 0:00, which would make column A look like the times you require. But note that these would still not be the genuine time values you require and you would still need to calculate the column B values before you could calculate with them successfully.

Note that you could hide column A after you have completed entering your data. Alternatively, you could put the data entry column somewhere out of the way - perhaps even on a separate sheet.

I trust this helps.
