Wife obtain and produced bank statement without court order or husband consent -divorce/maintainance

If this account is in your single name issue a legal notice to the bank for breach of trust and demand damages. 

It's my official salary account. I am surprised how they have the access to my account. Some internal guy have done it.

See whether court has ordered or not .

Court has ordered based on my salary declaration but wife has put my account statements without anyone permission or ask.this is illegal 

The wife has every right to know about the husband's salary after marriage. If she has gotten the bank statement through RTI or through a court order then no actions can be taken against her. Furthermore, the bank cannot share any statements to a third party without the consent of the account holder. The bank’s action was a clear breach of trust of the account holder's privacy.

There is no court order or my consent. Its obtained illegally 

As already advised you can sue the bank for breach of trust and demand damages.
