Super-large tonnage dry-type smoothing reactor coil demoulding lifting hook and its lifting method

Abstract

The invention belongs to the field of transformer manufacturing, in particular to a super-large-tonnage dry-type smoothing reactor coil demoulding lifting hook and its lifting method. The hook includes a hanging plate, a supporting plate and a baffle plate. There are baffles connected, and multiple hanging plates with lifting holes are evenly distributed on the supporting plate between the two ends of the baffles, and dry smoothing reactors are respectively placed between two adjacent hanging plates and between the baffles and the hanging plates. The lower bus bar of the reactor coil, the lower bus bar located between the baffle plate and the hanging plate is connected to the baffle plate to realize the positioning of each lower bus bar of the dry-type smoothing reactor coil; the method is to pre-put the hook into the lower bus bar The lower part adopts the structural form of one hook supporting three lower busbars. A total of four hooks are pre-installed. After the mold is installed, the coil is wound. The inside of the coil is penetrated and lifted. The hook of the invention has a simple structure and is easy to use; the lifting method is simple and practical with high efficiency, and the coil body will not be deformed and cracked due to external force.

Description

technical field [0001] The invention belongs to the field of transformer manufacturing, in particular to a super-large-tonnage dry-type smoothing reactor coil demoulding lifting hook and a lifting method thereof. Background technique [0002] In the prior art, the upper and lower busbars of the dry-type flat resistance coil are made of aluminum alloy, and the aluminum alloy plate used for each busbar is only 20mm thick and about 200mm wide; while the coil weighs 65 tons, the coil mold The weight is at least 10 tons, the width of the coil is 1.5-3 meters, and the outer diameter of the coil is 5.6 meters. [0003] During the coil winding process, according to the number of coil winding layers and the product winding time, the product needs to be dried in the oven at least twice. After the coil winding is completed, the mold should be taken off. For the above requirements, it is impossible to use the four-claw spreader for normal products to lift the coil, and before the dry-...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the problem that the lifting requirements of the dry-type smoothing reactor coil cannot be met, and the coil is prone to deformation due to external force during the lifting process, the purpose of the present invention is to provide a super-large tonnage dry-type smoothing reactor coil demoulding Lifting hook and its lifting method
