Problems solved by technology

Since the size of the studs welded on the foot cannot be changed, when the clamp screws at both ends of the clamp are tightened, the lower yoke of the iron core cannot be effectively clamped, resulting in that the noise of the iron core cannot be effectively controlled

Embodiment Construction

[0009] The dry-type transformer core fastening base of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0010] see figure 1 , The dry-type transformer core fastening base of the present invention includes a base 1 , a lower clip 2 , a fixing part 3 , a nut 23 , a fastener 4 and an insulating part 5 . There are two fixing parts 3, which are respectively fixed on the two ends of the base 1, and can be designed in one piece. There are two lower clamping parts 2 , the middle clamps the iron core, and the two lower clamping parts 2 are both arranged between the two fixing parts 3 . Each lower clip 2 includes a half-frame foot 21 and a spacer 22 . The cushion block 22 is arranged at the lower end of the semi-frame-shaped foot 21, which can relieve the vibration of the iron core piece. The opening of the semi-frame-shaped foot 21 faces outwards, and a nut 23 is welded at the opening. Through holes are provided at cor...

Abstract

The invention provides a fastening base for an iron core of a dry-type transformer. The fastening base comprises a base, two lower clamping parts and fastening parts, fixing parts are respectively arranged at two ends of the base, the two lower clamping parts are disposed between the two fixing parts, a nut is fixedly disposed on the outer side of each lower clamping part, through holes corresponding to the nuts are arranged on the fixing parts, and the nuts penetrate through the through holes, so that the lower clamping parts are connected with the fastening parts and connected with the corresponding fixing parts. The fastening base can uniformly and effectively clamp the iron core, accordingly, vibration of an iron core plate is reduced, and noise is effectively lowered.

Description

technical field [0001] The invention belongs to the field of transformer manufacturing, and in particular relates to a dry-type transformer iron core fastening base. Background technique [0002] Compared with traditional oil-immersed transformers, dry-type transformers are used more and more due to fire prevention, no leakage, and environmental protection. Dry-type transformers are generally used in densely populated residential areas and places with high fire protection requirements, such as airports. , factories, shopping malls and other places. These users have higher and higher requirements for transformer quality, especially for transformer noise. The noise is mainly emitted by the iron core of the dry-type transformer. In addition to the material of the core, the magnetic density, and the processing of the core pieces, the clamping force of the stacked cores also has a great influence on the noise. The clamping of the lower part of the existing dry-type tran...
