Transformer coil lifting beam

Abstract

The invention discloses a transformer coil lifting beam, and particularly relates to a lifting mechanism for demoulding of a transformer. The transformer coil hanging beam comprises at least three mutually connected radial lifting arms, wherein a group of suspension positioning mechanisms are arranged on each lifting arm in the length direction and a lifting hook is arranged above each lifting arm. The lifting arms of the lifting beam have a certain adjustable range and can be used for the demoulding of transformer coils with different outer diameters, so that the commonality of the lifting beam is enhanced and the cost is reduced. Moreover, the structure of a top cover can meet the purification requirement, so that fallen metal chips or other foreign matters due to wear in running can be effectively prevented from being in contact with the coils and are convenient for users to clean regularly, and local discharge of the transformer due to the foreign matters is avoided at the same time.

Description

technical field [0001] The invention relates to a transformer coil hanging beam, in particular to a lifting mechanism for transformer coil demoulding. Background technique [0002] For a period of time, after the coil of the oil-immersed transformer has been wound on the mold, it usually uses a special iron pressure ring, screw and steel wire rope to cooperate with the demoulding process. The specific method is: use a screw and a special pressure ring to fasten the coil into a whole, and then use a crane and a wire rope to demould. The reason why the special iron pressure ring is "special" is because it needs to be made according to the inner diameter of each coil. A transformer needs to use up to 30 pieces of special iron pressure rings and 90 screws. Making special iron pressing rings and storing a large number of special iron pressing rings has brought a lot of trouble, but it is the key device for coil demoulding and is indispensable. [0003] The disadvantage of this ...

The reason why the special iron pressure ring is "special" is because it needs to be made according to the inner diameter of each coil. A transformer needs to use up to 30 pieces of special iron pressure rings and 90 screws. Making special iron pressing rings and storing a large number of special iron pressing rings has brought a lot of trouble, but it is the key device for coil demoulding and is indispensable

[0003] The disadvantage of this method is that the special iron pressure ring is used in a large amount, each is different, the production workload is very large, the equipment limitation and the processing cost are high; the second is that the special iron pressure ring is not universal, and the used special iron The pressure ring needs to be stored for rectification and use. If things go on like this, the storage space is insufficient, and it is inconvenient to find during the rectification; the third is that some special iron pressure rings cannot be rectified, so they have to be scrapped, resulting in waste of cost; Fastening the coil with the iron pressure ring is time-consuming and labor-intensive
