Shell type transformer lead clamping structure and clamping method

Abstract

The invention relates to a shell type transformer lead clamping structure and clamping method, and belongs to the technical field of transformers. According to the technical scheme, a first fixing plate and a second fixing plate are welded to a box cover, one end of each first supporting plate and one end of each second supporting plate are fixedly connected with the first fixing plate and the second fixing plate respectively, the other end of each first supporting plate and the other end of each second supporting plate are fixedly connected with the two ends of transverse plates respectively, a lead passes through a circular hole formed by matching two semicircular holes which are formed in a first lead clamping plate and a second lead clamping plate, the first lead clamping plate and the second lead clamping plate are fixed to the middle of the transverse plates respectively, the other end of the first lead clamping plate and the other end of the second lead clamping plate are fixed together through a lead fixing plate, and the shell type transformer lead is clamped and fixed. According to the clamping structure and clamping method, the supporting plates and the transverse plates are connected vertically and horizontally, the lead is firmly fixed by the semicircular holes of the lead clamping plates, on the premise that shell type transformer lead meets the insulation distance, the clamping structure is simple in structure, reliable in fixation and convenient to operate, the lead is lengthened to electric creep distance of the box cover to the maximum extent, and performance of products is guaranteed.

Description

technical field [0001] The invention relates to a clamping structure and a clamping method for lead wires of a shell-type transformer, belonging to the technical field of transformers. Background technique [0002] At present, the lead wire clamping of conventional core-type transformer products is mostly welded to the bottom plate on the web of the clamp, and then the lead wire is fixed firmly by the wire clamp under the premise of ensuring the insulation distance. A shell-type transformer is a type of transformer in which the iron core and yoke composed of laminations surround the winding (generally surrounding most of the winding). The wire cake of the shell-type transformer is placed vertically, and the lead wires are drawn from the upper part of the wire cake. Background The technical problems are: complex structure, inconvenient operation, poor firmness and reliability of lead wire clamping. Contents of the invention [0003] The object of the present invention is t...
