Abstract
The invention discloses a leak detection method of a plate radiator for a transformer. The leak detection method is conducted in a water trough and comprises the following steps: a, water in the water trough is checked, and if the water is turbid, the water is replaced by new water; b, a sealing fixture is mounted on either an oil inlet or an oil outlet of the radiator to be detected, and whether an air relief cock is screwed tightly is checked; c, the interior of the radiator obtained from Step b is pressed to 170 KPa, the radiator is placed in the water trough, each plate is observed carefully, a mark and a record are made if a leak spot is found, then, the radiator is overturned by 180 degrees and placed in the water trough, the pressure is maintained for 20 minutes, and the mark and the record are made if the leak spot is found; d, if the leak spot exists in the radiator in Step c, the radiator is hoisted out by a travelling crane, and the leak spot is repaired and welded according to a position of the leak spot; and e, Step c and Step d are repeated till no leak spot exists. With the adoption of the mode, the leak detection method can prevent the leak spot effectively and ensure the normal operation of the transformer.
