A compression and anti-loosening mechanism for the main column iron core of shunt reactor

Abstract

The invention discloses a compressing looseness-proof mechanism for a main column iron core of a shunt reactor. The mechanism comprises a plurality of tensioning screws, a locking plate and a looseness-proof plate, wherein the locking plate is arranged below a main column iron core lower yoke, the looseness-proof plate is arranged below the locking plate, and the plurality of tensioning screws penetrate a disc spring structure, a main column iron core upper yoke, the main column iron core lower yoke, the locking plate and the looseness-proof plate vertically; the disc spring structure is located above the main column iron core upper yoke; a retaining slot is formed in the upper end part of each tensioning screw, symmetrically distributed plane structures are arranged at the lower end part of the tensioning screw, the retaining slot in the tensioning screw extends out of the upper surface of the disc spring structure, a first looseness-proof nut is screwed in a position, below the retaining slot, of the tensioning screw, a looseness-proof washer is mounted in the retaining slot, and a second looseness-proof nut is screwed in a position, above the retaining slot, of the tensioning screw. The mechanism improves the compressing looseness-proof effect on the main column iron core, facilitates maintenance, reduces the maintenance workload, is simple and firm in structure and easy to realize and has good application prospect.

Description

technical field [0001] The invention relates to the technical field of reactor components, in particular to a compression and anti-loosening mechanism for the main column iron core of a shunt reactor. Background technique [0002] Due to the special core structure of the shunt reactor, the vibration of the shunt reactor is inherent, which can only limit the amplitude of the vibration to a certain extent, but cannot completely eliminate the vibration. Therefore, during the design, manufacture and operation of shunt reactors, iron core vibration is a problem that needs to be paid close attention to in the development, design and operation of shunt reactors. At present, although the manufacturer has adopted anti-loosening and vibration reduction measures in the design, it is often found that the vibration of the core shunt reactor exceeds the standard during operation. Therefore, the anti-loosening and vibration reduction of large iron core shunt reactors is one of the most im...
