The utility model provides a 110 220 processing apparatus is adsorbed in electrification of kilovolt main transformer oil, the device is main includes transformer, vacuum oil filter and valve group, the utility model discloses a select its both sides radiator oil pump department business turn over oil circulation interface of diving to the 220KV transformer, does not easy and simple to handlely change original oil stream direction again, business turn over oil department installation valve with controlled flow rate no longer than the former oil pump velocity of flow of diving, can avoid the oil stream electrified, can guarantee the normal operating operating mode of transformer. Select bottom fuel outlet valve department oil feed to the 110KV transformer, oil tank top oil strain valve produces oil, and the diagonal is arranged also can not change the oil stream direction by the interface, practice has proved that 100L's minute the velocity of flow can satisfy the safe operation.
