Baking device and method of immersion type dry-type transformer

Abstract

The invention discloses a baking device and method of an immersion type dry-type transformer. The baking device of the immersion type dry-type transformer comprises a drying furnace and a clamp for fixing the immersion type dry-type transformer to be dried. The drying furnace is internally provided with a first rotating shaft and a second rotating shaft, wherein the first rotating shaft and the second rotating shaft are horizontally and parallelly arranged. The clamp comprises a first circular disc and a second circular disc, wherein the first circular disc and the second circular disc are arranged in parallel and have equal diameters, and the immersion type dry-type transformer is fixed between the first circular disc and the second circular disc. The first rotating shaft and the second rotating shaft are separately supported on circular tangent planes on the two sides of the lower portion of the first circular disc and circular tangent planes on the two sides of the lower portion ofthe second circular disc, and when at least one of the first rotating shaft and the second rotating shaft rotates, the first circular disc and the second circular disc can be driven to rotate around respective center lines. According to the baking device, as the immersion type dry-type transformer in a rotary oven is in a rotating state, the phenomenon of uneven paint film with a thin upper paintfilm and a thick lower paint film in the drying and curing process is further avoided; and meanwhile, the problem of airway obstruction is solved.

Description

technical field [0001] The invention relates to the technical field of dry-type transformer processing technology, in particular to a baking device and method for an impregnated dry-type transformer. Background technique [0002] Generally speaking, dry-type transformers are divided into cast-type transformers and impregnated dry-type transformers. For impregnated dry-type transformers, it must be baked after dipping. At present, most of the baking of impregnated dry-type transformers adopts static baking, that is, the transformer after dipping paint is placed in a hot air circulation furnace for drying for a certain period of time to cure the paint film. Static baking method is prone to uneven distribution of transformer paint film thickness after dipping and baking (the upper paint film is thinner and the lower paint film is thicker), and it is prone to lacquer tumors that cause airway obstruction, which directly affects the dipping type. Performance of dry-type transform...
