Waterproof transformer and its assembly process

Abstract

The invention provides a waterproof type mutual inductor and an assembling process therefor. An iron core adopts an annular structure which is formed by a left half ring and a right half ring; a framework adopts an annular structure which is formed by a left half part and a right half part; the left half ring and the right half ring are embedded in the left half part and the right half part respectively; mounting baffles are arranged on the end planes of the left half part and the right half part; the mounting baffles are sleeved with waterproof cushions; a shell comprises a left half shell and a right half shell; C-shaped embedding grooves for placing the left half part and the right half part which form the framework are formed in the left half shell and the right half shell respectively; shell tightly-fitting grooves are vertically formed in the groove walls of the embedded grooves of the left half shell and the right half shell; the two sides of the waterproof cushions are embedded in the shell tightly-fitting grooves; and the embedded grooves for placing the left half part and the right half part of the framework are filled with epoxy resin. The waterproof type mutual inductor is good in the sealing effect.

Description

technical field [0001] The invention relates to a transformer, in particular to a novel transformer with strong waterproof function and its assembly process. Background technique [0002] At present, energy saving and emission reduction are advocated at the national level. Therefore, the open-close application structure of the transformer has been widely used due to its advantages of convenient installation, repeatable disassembly and assembly, and low maintenance costs; however, because the transformer is used outdoors Work, there will be rain erosion on it, especially for this type of open-close structure transformer, if the end face of the iron core is attacked by rainwater, the accuracy will drop sharply, thereby greatly reducing the accuracy of the transformer. [0003] Nowadays, in order to achieve the waterproof effect, the outdoor transformers on the market simply carry out end surface treatment, such as adding a waterproof pad, such as "a transformer with a waterpro...

Problems solved by technology

[0002] At present, energy saving and emission reduction are advocated at the national level. Therefore, the open-close application structure of the transformer has been widely used due to its advantages of convenient installation, repeatable disassembly and assembly, and low maintenance costs; however, because the transformer is used outdoors Work, there will be rain erosion on it, especially for this type of open-close structure transformer, if the end face of the iron core is attacked by rainwater, the accuracy will drop sharply, thus greatly reducing the accuracy of the transformer

[0003] Nowadays, in order to achieve the waterproof effect, the outdoor transformers on the market simply carry out end surface treatment, such as adding a waterproof pad, such as "a transformer with a waterproof shell" disclosed in Chinese patent 201410226586.3, which does not start from the overall structure The waterproof performance is designed on the above, so it cannot achieve a good waterproof effect
