Embodiment Construction

[0021] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0022] The large-scale transformer body compression system is composed of upper and lower clamps, steel straps, pull plates, pressure nails, nail holders, anti-lock nuts, etc. Among them, the upper and lower clamps, steel pull belts, and pull plates form an effective steel whole.

[0023] The compression structure adopts the structural form of pressing nails around and connecting the upper and lower pull-down plates. The pull-plate connection structure connects the upper and lower clamps, making the body a whole steel body. The silicon steel sheet does not shift up and down during the tightening process, and the nail structure is used to tighten the body.

[0024] The role of the tie plate connection structure is to connect the upper and lower clamps to form a stable steel body, which plays a role of support and clamping when the body...

Abstract

The invention discloses a large transformer body compression device and compression technology, and relates to the technical field of transformers. The large transformer body compression device comprises a pulling plate connection structure, pull stripe structures and press nail structures, wherein the press nail structures are separately arranged at the left side and the right side of a transformer body and the front side and the rear side of the transformer body; each press nail structure comprises a screw rod, a compression nut, a support sleeve and a spring; each spring is arranged in each support sleeve; a polish rod is arranged at one end of each screw rod, is arranged on the spring in each support sleeve, and can be in sliding fit with each support sleeve; a locking nut is arranged on each screw rod; and an air hole is formed in the side wall of each support sleeve. According to the large transformer body compression device and compression technology, the compression degree of the transformer body can be improved, so that safe operation of an overall power grid is improved.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to a compacting device and a compacting process for a large transformer body. Background technique [0002] The transformer is an important part of the power system. The stability and reliability of the transformer is directly related to the normal operation of the power grid, and the compactness of the transformer body determines the ability of the transformer to withstand short-circuit under short-circuit conditions. Instances of damage to the transformer due to the decline in the short-circuit resistance of the transformer caused by the unreasonable design of the compact structure and the non-standard compaction process of the body occur from time to time. Therefore, in view of the unreliable compaction of the existing transformers, the compaction structure and compaction process of the transformer body need to be continuously improved, so as to effectively ensure the assemb...
