Abstract

This utility model is a non-encapsulating voltage transformer iron core clipping, which comprises bolts and thin nuts equipped on prone surface screwed holes of the upper and the lower clipping components. The distance is adjustable according to the blueprint. Sides bolts are further equipped through the fixed holes of the upper and the lower clipping components, and nuts are employed to lock the side bolts, the clipping components and the iron core. Finally bolts of each part are adjusted according to the blueprint and thin nuts are employed to lock and thereby ensuring each parts of the voltage transformer iron yoke to be fixed closely. This utility model has the advantages that the fixation of the iron core are achieved through this conformation and the loose parts are ensured of fixation of each parts of the iron core through adjusting nuts. This conformation not only simplifies the production arts, cuts down a production and processing procedure, promots production efficiency, but also shortens production cycle, reduces the noise of the product and promotes the electrical performance of the product. This utility model is capable of forming a serial design of a volume of 100-3150kVA and ensuring excellent operation conditions of the product.

Description

Core Clamping Structure Of Non-encapsulated Dry-type Transformer

Technical field

The utility model relates to a kind of Core Clamping Structure Of Non-encapsulated Dry-type Transformer that is applicable to, belong to the transformer accessory technical field.

Background technology

The clamping structure unshakable in one's determination of no-encapsulated-winding dry-type transformer of the prior art, be by the folder insulation being fixed on the outside of belly plate of upper clamping piece and lower clamping piece earlier, and then pass with other screw rod in the fixing hole of upper and lower folder upper clamping piece and lower clamping piece and iron core clamping with screw.The not tight phenomenon of the local folder of upper and lower iron yoke can appear in this structure, thereby causes the noise of product to increase.

Summary of the invention

The purpose of this utility model is the defective at above-mentioned existence, proposes a kind of improved Core Clamping Structure Of Non-encapsulated Dry-type Transformer.Realize clamping unshakable in one's determination by this structure.

Technical solution of the present utility model: its structure is earlier bolt, thin nut to be threaded onto on the outside of belly screwed hole of upper and lower folder, and the distance size is decided according to drawing; Pass in the fixing hole of upper and lower folder with other screw rod then, with nut other screw rod, folder and iron core are locked again, require to regulate the bolt at each position at last according to drawing, and lock, thereby each position that guarantees the transformer fe yoke is all clamped with thin nut.

Advantage of the present utility model: realize clamping unshakable in one's determination by this structure, the place not tight for the part folder guarantees that by adjusting nut each position unshakable in one's determination is all clamped.This structure had both been simplified production technology, had reduced the production and processing operation one, had improved production efficiency of products, had shortened life cycle of the product, and had reduced the noise of product, had improved the electric property of product.The utility model can form the Series Design of 100～3150kVA capacity, and can guarantee that the product operation conditions is good.

Description of drawings

Accompanying drawing 1 is an example structure schematic diagram of the present utility model

In the accompanying drawing 1 is that bolt, 2 is first to be thin nut, the 3rd, and upper and lower folder, the 4th is unshakable in one's determination, the 5th, and other screw rod, 6 is second thin nuts.

Embodiment

The contrast accompanying drawing, its structure is that bolt 1, first, second

thin nut

2,6 are spun on the outside of belly screwed hole of upper and lower folder 3; Pass the fixing hole of upper and lower folder 3 with other screw rod 5, other screw rod 5, upper and lower folder 3 and unshakable in one's determination 4 are locked with nut.And lock with thin nut, thereby each position that guarantees the transformer fe yoke is all clamped.

During making, bolt, thin nut are threaded onto on the outside of belly screwed hole of upper and lower folder, the distance size is decided according to drawing; Pass in the fixing hole of upper and lower folder with other screw rod then, with nut other screw rod, folder and iron core are locked again, require to regulate the bolt at each position at last according to drawing, and lock with thin nut.

Claims

1, Core Clamping Structure Of Non-encapsulated Dry-type Transformer is characterized in that it being that bolt (1), first, second thin nut (2,6) are spun on the screwed hole of upper and lower folder (3) outside of belly; Pass the fixing hole of upper and lower folder (3) with other screw rod (5), other screw rod (5), upper and lower folder (3) and iron core (4) are locked with nut.
