Embodiment 1

[0030] This embodiment provides a three-phase five-column amorphous alloy transformer, such as figure 1As shown, the three-phase five-column amorphous alloy transformer includes an amorphous alloy, a coil, a clip, a transformer frame 1 and a transformer box 5; the amorphous alloy dry-type transformer adopts a three-phase five-column transformer, and the transformer frame 1 Located in the transformer box 5, the transformer frame 1 supports the overall amorphous alloy dry-type transformer; the amorphous alloy includes an upper iron yoke, a lower iron yoke, and an iron core column arranged between the iron yoke and the lower iron yoke, and the coil is sleeved on The iron core column clamps the amorphous alloy through clamps. The clamps are divided into upper clamp 2, lower clamp 6 and side clamp 3. The upper clamp 2 is fixed above the upper iron yoke by pressing nails and rubber, and the lower clamp Part 6 is also fixed under the lower iron yoke by pressing nails and rubber, and ...

Embodiment 2

[0034] In order to facilitate the assembly of the reinforcing rib 8 and save assembly time; for example Figure 7 As shown, the reinforcing rib 8 is composed of a first rectangular plate 81 and a second rectangular plate 82, the center position of the first rectangular plate 81 is welded and fixed with the center position of the second rectangular plate 82, and the second rectangular plate 82 is welded and fixed. Both ends of a rectangular plate 81 in the axial direction are provided with a groove A83, and the opening end of the groove A83 faces the bottom of the first rectangular plate 81, and the width of the groove A83 is consistent with the thickness of the upper clamp 2; The square plate 81 is buckled on the top of the upper clamp 2 through the groove A83; the two ends of the second rectangular plate 82 in the axial direction are also provided with a groove B84, and the opening section of the groove B84 faces the bottom of the second rectangular plate 82 , the width of th...

Abstract

The invention provides a three-phase five-column type amorphous alloy transformer. The three-phase five-column type amorphous alloy transformer comprises an amorphous alloy, a coil, a clip, a transformer frame and a transformer tank, wherein the clip is divided into an upper clip, a lower clip and a side clip; the transformer further comprises a noise reducing device; the noise reducing device comprises a strengthening bar and a shock-absorbing device; the shock-absorbing device is divided into a first shock-absorbing device and a second shock-absorbing device; the second shock-absorbing device comprises a lower fixing plate and lower shock absorbers; the lower fixing plate is connected with the transformer tank via the lower shock absorbers; a shock-absorbing cavity is disposed on the lower fixing plate; the lower shock absorbers are disposed inside the shock-absorbing cavity; the number (N) of the the lower shock absorbers at the bottom of the lower clip is no less than three; the central location of the bottom of the transformer frame is provided with the lower shock absorber all the time; and the rest of the shock absorbers are centrally symmetric in distribution with respect to the central shock absorber. According to the transformer provided by the invention, the shock passing between the amorphous alloy and the transformer tank is reduced to the maximum by adopting multiple shock absorption, and the anti-shock performance of the noise-reducing device is effectively improved; and the assembling of the shock absorbing device is simple and easy.

Description

technical field [0001] The invention relates to the technical field of transformer equipment, in particular to a three-phase five-column amorphous alloy transformer. Background technique [0002] With the rapid development of the power grid, dry-type transformers are relatively common power transmission devices in the power grid. When the transformer is used in a humid environment for a long time, the insulation of the coil winding in the transformer will decrease, which will affect the stability of use to a certain extent. In addition, the transformer will vibrate during operation, which will cause certain pollution to the environment. At the same time, the long-term vibration of the transformer will also affect the service life of the transformer, and the applicability and practicability are limited. [0003] For example, Chinese patent CN203013483U discloses a high-efficiency silent amorphous dry-type transformer. Molded parts and transformer bases, characterized in that...
