Marine transformer poured with epoxy resin

Abstract

The invention discloses a marine transformer poured with epoxy resin, relating to the marine transformer field of pouring and curing a coil and a core of a marine transformer by using the epoxy resin. A fastening piece (2) tightly presses a transformer coil (8) through a transformer pressing block (1), a primary connecting terminal (5) and a secondary connecting terminal (10) are mounted on the fastening piece (2) through a terminal board (4), an internal connecting cable (6) and an external connecting cable (7) are connected to a coil outgoing line terminal (9), the internal side and the external side of a primary coil (16) and a secondary coil (17) are fixed through an air flue rod (11) in the transformer coil (8), and an epoxy resin layer (19) is poured at the internal side and the external side of the primary coil (16) and the secondary coil (17), an epoxy resin thick slurry layer is painted at two end faces of a transformer core (3), and some air flues (18) are arranged in the air flue rod (11). The marine transformer poured with the epoxy resin has favorable transformer insulation property, high mechanical strength, and no noise in operation, and can satisfy the three-proof requirements of the transformer.

Description

Technical field: [0001] The epoxy resin casting marine transformer of the present invention relates to the field of marine transformers in which epoxy resin is poured and solidified for coils and iron cores of the marine transformer. Background technique: [0002] Existing marine transformers adopt the method of multiple immersion paint treatment for the transformer coils wound by copper wires to achieve the purpose of moisture resistance, but with the rapid development of my country's shipbuilding industry, users have higher and higher requirements for the operational reliability of marine transformers Therefore, the insulation performance of marine transformers is far less reliable than that of epoxy resin cast and cured only by dipping paint. Invention content: [0003] The object of the present invention is to provide a kind of epoxy resin casting marine transformer, adopt vacuum casting epoxy resin to the marine transformer coil, brush the thick layer of epoxy resin on...
