Abstract

The invention discloses a hot galvanizing finned radiator for an SF6 gas insulated transformer, which comprises an SF6 gas radiator, and a zinc layer is attached to the surface of the SF6 gas radiator; the hot galvanizing process comprises the following steps: pickling the surface of the SF6 gas radiator by using a hydrochloric acid washing solution with a certain concentration; the SF6 gas radiator is put into a water washing tank to be fully washed; the SF6 gas radiator is put into the medicament solution to be fully soaked; the SF6 gas radiator is put into zinc liquid to be soaked, and ammonium chloride is evenly scattered into the zinc liquid; the cooled SF6 gas radiator is put into a passivation liquid tank to be subjected to passivation soaking; and the polished and trimmed SF6 gas radiator is subjected to dehydrogenation treatment. By adopting the process, the plating layer has the advantages of low treatment cost, wide environment adaptability and attractive and flat appearance, the hot galvanizing process and the SF6 gas radiator are effectively and perfectly combined, and the operating age limit and the safety coefficient of the transformer are improved.

Description

technical field [0001] The invention relates to the technical field of hot-dip galvanized sheet radiators, in particular to a SF 6 Hot-dip galvanized fin radiators for gas-insulated transformers. Background technique [0002] Currently, fin radiators are SF 6 One of the main cooling devices used in the gas insulated transformer industry, the SF in operation 6 The heat generated by the gas-insulated transformer causes the SF in it 6 As the gas temperature increases, the SF in the transformer 6 The gas circulates in the fin radiator and conducts heat conduction with the surrounding air, thereby dissipating the SF in the transformer 6 The gas is cooled to ensure the safe operation of the transformer. Domestically produced SF at this stage 6 The anti-corrosion method of gas radiators generally adopts paint coating to form a paint film on the surface of the product to protect the product from corrosion. However, this kind of fin radiators coated with paint is prone to pain...
