Abstract：Forced-oil circulated air-cooler has been used widely in the 220kV’s main transformer, the completed shutdown tripping circuit of the cooler is the important one in the secondary circuit. The articles attends to analysis the completed shutdown tripping circuit in the forced-oil circulated air-cooler and make corresponding suggestions for the existing problems.

Key words： main transformer in 220kV substation forced oil circulation air cooling timing relay the completed shutdown trip of the air-cooler
