Abstract
The invention discloses a low-noise enhancement type amorphous transformer. The low-noise enhancement type amorphous transformer comprises an iron core, a box body, reinforcing pipes, and sound-absorption fillers, wherein the box body is a rectangular thin-wall metal container; the reinforcing pipes are arranged between the inner wall at the bottom of the box body and the iron core; the interiors of the reinforcing pipes are filled with the sound-absorption fillers; the reinforcing pipes are welded and fixedly connected on the surrounding inner walls at the bottom of the box body to form an annular sealed structure; and low-noise enhancement type amorphous transformer is further improved in that the outer wall of the box body is coated with a sound-absorption material; and the sound-absorption fillers adopt yellow sand. The low-noise enhancement type amorphous transformer is high in structural strength, low in production cost and low in noise.
Description
Technical field
The present invention relates to transformer technology field, and in particular to a kind of amorphous transformer.
Background technology
Amorphous transformer is a kind of energy saving transformer, and noise figure size is the important of evaluation amorphous transformer running quality
Content.Existing amorphous transformer generally comprises iron core, casing, reinforced pipe, sound-absorbing filler, and casing is rectangular thin-wall canister,
Its structure affects larger to running noises, is that noise, Authorization Notice No. are reduced on the premise of production cost is not increased
The Chinese patent of CN203456260U discloses a kind of built-in noise-reducing structure of amorphous transformer：The bottom both sides inwall of casing with match somebody with somebody
It is fixedly connected reinforced pipe between the iron core of set along the length direction, strengthens completely filling in sound-absorbing filler composition column noise abatement knot in tube chamber
Structure.This structure can reach reduce on the premise of production cost is not increased the purpose of noise, but also have existing defects：Strengthen
The wall box intensity at pipe two ends is still poor, causes noise reduction effect unobvious.
The content of the invention
The present invention is directed to the deficiencies in the prior art, proposes that one kind can significantly improve body structure intensity, rigidity, so as to notable
Reduce the low noise enhancement mode amorphous transformer of noise.
The present invention is achieved through the following technical solutions technical goal.
Low noise enhancement mode amorphous transformer, including iron core, casing, reinforced pipe, sound-absorbing filler；The casing is Thin Rectangular
Wall canister；The reinforced pipe is arranged between box bottom inwall, iron core, is strengthened tube cavity and is filled up sound-absorbing filler；It changes
Entering part is：The reinforced pipe is welded and fixed and is connected on box bottom surrounding inwall, forms annular enclosed type structure.
In said structure, the cabinet exterior lays sound-absorbing material.
In said structure, the sound-absorbing filler is yellow ground.
The present invention compared with prior art, has the positive effect that：
1. reinforced pipe is welded and fixed and is connected on box bottom surrounding inwall, forms annular enclosed type structure, the week side of boss wall of casing four
It is linked to be entirety with reinforced pipe, significantly improves body structure intensity, rigidity, so as to substantially reduces noise；On the other hand, the four of iron core
It is designed with sound-absorbing filler week, further reduces noise.
2. cabinet exterior lays sound-absorbing material, further reduces noise.
3. sound-absorbing filler is yellow ground, and with low cost, sound-absorbing effect is good.
4. reinforced pipe is welded and fixed and is connected on box bottom surrounding inwall, occupies bigger idle space, greatly reduces
The interior amount for storing cooling oil, so as to save production cost, mitigates the burden of user.
Description of the drawings
Fig. 1 is schematic structural view of the invention.
Fig. 2 is the top view of Fig. 1.
Fig. 3 is I enlarged schematic partial view in Fig. 1.
Specific embodiment
Below according to accompanying drawing and in conjunction with the embodiments the invention will be further described.
The amorphous transformer of low noise enhancement mode shown in accompanying drawing, including iron core 1, casing 2, reinforced pipe 4, sound-absorbing filler 5；Casing
2 is rectangular thin-wall canister；Reinforced pipe 4 is arranged between the bottom interior wall of casing 2, iron core 1, and the inner chamber of reinforced pipe 4 fills up sound-absorbing
Filler 5, in the present embodiment, sound-absorbing filler 5 is yellow ground；Reinforced pipe 4 is welded and fixed and is connected on the bottom surrounding inwall of casing 2, shape
Circularize enclosed construction.
The outer wall of casing 2 lays sound-absorbing material 3.
