Problems solved by technology
[0004] The main purpose of the present invention is to provide a dry-type transformer production process, which aims to solve the problem that in the existing dry-type transformer production process, silicon steel sheets often need to be stored and waited for a period of time after being cut to form an iron core. If the storage time is too long, the surface of the silicon steel sheet will be oxidized and rusted, which will lead to a decrease in the quality of the finished iron core.

The invention discloses a production process for a dry-type transformer. The production process is applied to a silicon steel sheet storage device. The silicon steel sheet storage device comprises a storage box, a sealing door, an air pump, a first electromagnetic valve, a vacuum pump and a second electromagnetic valve, wherein the storage box is provided with an inlet for putting in or taking out silicon steel sheets; the sealing door can be arranged at the inlet in a sealing and covering manner; the inlet end of the air pump communicates with an external inert gas source; the outlet end of the air pump communicates with one end of the first electromagnetic valve; and the other end of the first electromagnetic valve communicates with the storage box. According to the production process for the dry-type transformer , the silicon steel sheets which are cut and are not used temporarily are stored in the silicon steel sheet storage box, and the silicon steel sheet storage box is filled with inert gas, so the silicon steel sheets stored in the silicon steel sheet storage box are not prone to oxidization and rusting; and therefore the quality of iron core finished products is guaranteed, and the finished product quality of the final dry-type transformer is ensured.
Description
technical field [0001] The invention relates to the technical field of transformer production, in particular to a dry-type transformer production process. Background technique [0002] Dry-type transformers are widely used in local lighting, high-rise buildings, airports, docks and other places. Simply put, dry-type transformers refer to transformers whose iron core and windings are not immersed in insulating oil. The dry-type transformer is mainly composed of an iron core composed of silicon steel sheets and a coil casted by epoxy resin. An insulating cylinder is placed between the high and low voltage coils to increase electrical insulation, and the coils are supported and restrained by pads, and fasteners for overlapping parts Both have anti-loose performance. Due to the advantages of strong short-circuit resistance, small maintenance workload, high operating efficiency, small size, and low noise, dry-type transformers are often used in places with high performance requi...
