Abstract
The utility model provides a kind of bellows for transformer vibration absorber and transformer, and described vibration absorber comprises fixed lever and cushion blocking, and described fixed lever is fixed on two flanges of bellows two ends, and described cushion blocking pad is located between fixed lever and bellows.This vibration absorber can solve vibration and the noise problem of bellows.
Description
Technical field
The utility model belongs to transformer manufacture technology, is specifically related to a kind of bellows for transformer damping device and the transformer comprising this device.
Background technology
Along with the development of power industry, power transformer forward superhigh pressure, ultra high voltage, Large Copacity, high-environmental future development, and the electric pressure of transformer is higher, capacity is larger, and the cooling capacity of the cooler that matched transformer is standby is also just corresponding to be strengthened, to meet the cooling requirement of transformer simultaneously.Obviously, single cooler cooling capacity strengthens and cooler oil pump and power of fan will inevitably be made to strengthen, and cooler makes the vibration of coupled Oil Guide bellows will be more violent in running, what long-term high vibration brought is high-decibel noise and makes Oil Guide bellows be damaged and have the risk of leakage of oil, and these all cause adverse influence to the operation of transformer.
Therefore, need a kind of vibration damping scheme badly, to solve the vibration problem of bellows.
Utility model content
Technical problem to be solved in the utility model is for above shortcomings in prior art, provides a kind of and can solve the bellows for transformer vibration absorber of bellows vibration and noise problem and comprise the transformer of this device.
The technical scheme that solution the utility model technical problem adopts is that this bellows for transformer vibration absorber comprises fixed lever and cushion blocking, described fixed lever is fixed on two flanges of bellows two ends, and described cushion blocking pad is located between fixed lever and bellows.
Preferably, described fixed lever adopts screw rod, and described screw rod is also provided with nut, and fastening nuts is on the flange face of flange.
Further preferably, described screw rod adopts four, and four screw rods are arranged on the both sides of bellows between two, and two of the same side screw rods run through the upper and lower of flange respectively.
Preferably, the nut on every root screw rod is four, and four nuts on same screw rod are fastened on four flange faces of two flanges respectively.
Preferred described cushion blocking adopts rubber to make.
The utility model also provides a kind of transformer, comprises transformer body, cooler, oil guide pipe and bellows, and described cooler is communicated with transformer body with bellows by oil guide pipe, and this transformer also comprises above-mentioned bellows for transformer vibration absorber.
The beneficial effect of the utility model bellows for transformer vibration absorber is: by the flange being fixed on Oil Guide bellows two ends that run through by four screw rods, and carry out fastening with nut, then cushion blocking on padding between screw rod and bellows, to be used as buffering, thus, bellows will no longer resonate with cooler, and noise will significantly reduce simultaneously, even can ignore.The transformer that this vibration absorber is particularly suitable for running in indoor transformer or hole uses.
The advantages such as the utility model vibration absorber also has simple structure, easily processes, and cost is low, remove and install conveniently, simple to operate, effectively reliable.

Embodiment
Below in conjunction with the accompanying drawing in the utility model, carry out clear, complete description to the technical scheme in the utility model, obviously, described embodiment is a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, the every other embodiment that those of ordinary skill in the art obtain under the prerequisite not making creative work, all belongs to the scope of the utility model protection.
The utility model bellows for transformer vibration absorber comprises fixed lever and cushion blocking, and described fixed lever is fixed on two flanges of bellows two ends, and described cushion blocking pad is located between fixed lever and bellows.
Preferably, described fixed lever adopts screw rod, and described screw rod is also provided with nut, and fastening nuts is on the flange face of flange.
The utility model also provides a kind of transformer, comprises transformer body, cooler, oil guide pipe and bellows, and described cooler is communicated with transformer body with bellows by oil guide pipe, and this transformer also comprises above-mentioned bellows for transformer vibration absorber.
Below in conjunction with embodiment, the utility model is described in detail.
Embodiment 1:
As shown in Figure 1, bellows for transformer vibration absorber in the present embodiment the transformer that is suitable for comprise transformer body 2, cooler 1, oil guide pipe 3 and bellows 4, cooler 1 is communicated with transformer body 2 with bellows 4 by oil guide pipe 3, wherein the effect of bellows 4 is to regulate alignment error, and this transformer also comprises bellows for transformer vibration absorber.Wherein, cooler 1 is strong oil cooler (being water cooler in this example).
In the present embodiment, described bellows for transformer vibration absorber comprises fixed lever and cushion blocking, respectively there is a flange two terminations of described bellows 4, on two flanges, correspondence offers perforation, fixed lever is fixed in the perforation of two flanges of bellows two ends, and described cushion blocking pad is located between fixed lever and bellows.
Preferably, described fixed lever adopts screw rod 5, and screw rod 5 is also provided with nut, and described nut screwing clamping is on the flange face of flange.
In the present embodiment, screw rod 5 adopts four, and four screw rods are arranged on the both sides of bellows between two, and two of bellows the same side screw rods run through the upper and lower of two flanges respectively.
Preferably, the nut on every root screw rod is four, and four nuts on same screw rod are fastened on four flange faces of two flanges respectively.Preferred cushion blocking 6 adopts rubber to make.
Like this, by the flange being fixed on bellows two ends that run through by four screw rods, and with fastening nuts, then rubber blanket on pad between screw rod and bellows, to be used as buffering.Like this, bellows will no longer resonate with cooler 1, and noise will significantly reduce simultaneously, even can ignore.
During transformer work, after cooler 1 is opened, oil guide pipe 3 and bellows 4 can be made to vibrate.And the quantity that cooler 1 is opened is more, then oscillation intensity is larger, and now oil guide pipe 3 and bellows 4 will produce larger noise because of vibration.After above-mentioned bellows for transformer vibration absorber in employing the present embodiment, the vibration of oil guide pipe and bellows is obtained and significantly reduces, also make noise problem obtain effective solution simultaneously.
Be understandable that, the illustrative embodiments that above execution mode is only used to principle of the present utility model is described and adopts, but the utility model is not limited thereto.For those skilled in the art, when not departing from spirit of the present utility model and essence, can make various modification and improvement, these modification and improvement are also considered as protection range of the present utility model.
