Abstract
The utility model discloses a transformer conservator structure. The structure comprises a corrugated expansion core body, an exhaust pipe, an oil level indication board, an oil filler pipe and a butterfly valve, wherein the upper part of the corrugated expansion core body is connected with the exhaust pipe, and the bottom of the corrugated expansion core body is connected with the oil filler pipe; the butterfly valve is arranged on the oil filler pipe; the oil level indication board is connected with the corrugated expansion core body; the corrugated expansion core body is provided with a longitudinal expansion joint, and is made of stainless steel. The corrugated core body (1Cr18Ni9Ti) of the transformer conservator structure is made of the stainless steel material with atmosphere corrosion resistance and high temperature resistance, can achieve the service life of reciprocating and retracting for over 20,000 times, can move up and down along with changes of oil temperature of the transformer, can be automatically compensated along with changes of the oil volume of the transformer, and has the characteristics of being simple in structure, convenient to assemble, easy to fill oil, long in service life, high in sensitivity and small in maintenance amount.
Description
Technical field
The utility model relates to a kind of installation for transformer structure.
Background technology
When the volume of transformer oil, along with oily temperature expansion or while reducing, conservator because variations in temperature expands, shrinks the volume-variation produced, plays important protective effect to the normal operation of safeguarding transformer in order to compensator transformer oil.
Installation for transformer is capsule-type mostly at present, and it opens the transformer oil in transformer body and air insulated.Along with oil temperature lifting in transformer, it is breathed, and enough space is arranged when oily volume changes.Its operation principle is that in collapsible bag, gas communicates with atmosphere by respiratory siphon and dehydrating breather, and the collapsible bag bottom surface is close on the pasta of oil conservator, and when pasta changes, collapsible bag also can expand thereupon or compress.Because collapsible bag may the be full of cracks micropore occur because of the material problem, air and moisture are infiltrated in oil and enter oil tank of transformer, cause water content in oil to increase, decreasing insulating, oily dielectric loss increases, and accelerates the ageing process of insulating oil.Therefore, transformer need to be changed silicon particle, when situation is serious, need to be forced to oil strain or interruption maintenance.
Summary of the invention
The technical problems to be solved in the utility model is to provide long installation for transformer structure of a kind of easy to use and life-span.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of installation for transformer structure comprises ripple expanding core body, blast pipe, oil level indicator board, oil fuel tube and butterfly valve; Ripple expanding core body top is connected with blast pipe, and bottom is connected with oil fuel tube, and oil fuel tube is provided with butterfly valve; The oil level indicator board is connected with the ripple expanding core body.
As preferably, the ripple expanding core body is provided with the longitudinal ripple expansion joint.
As further preferred, the ripple expanding core body is made by stainless steel.
The beneficial effects of the utility model are:
Ripple core body (1Cr18Ni9Ti) adopts the stainless steel with atmospheric corrosion resistance and heat-resisting ability, can meet more than 20,000 times and come and go the flexible life-span, core body moves up and down along with the variation of temperature of oil in transformer, and auto-compensation has compensation rate large along with the variation of transformer oil volume, simple in structure, easy for installation, oiling is easy, and the life-span is long, the characteristics highly sensitive, that maintenance is little.
The accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is the structural representation of the utility model installation for transformer structure embodiment.
In figure, 1-ripple expanding core body, 2-core body protective valve, 3-oil fuel tube, 4-butterfly valve, 5-blast pipe, 6-oil level indicator board, 7-observation window.
Embodiment
Fig. 1 is a kind of installation for transformer structure, comprises ripple expanding core body 1, blast pipe 5, oil level indicator board 6, oil fuel tube 3 and butterfly valve 4.
Ripple expanding core body 1 is provided with the longitudinal ripple expansion joint, can be by stretching up and down to carry out the oil mass compensation.Ripple expanding core body 1 top is connected with blast pipe 5, for being communicated with atmosphere, plays respiration.Ripple expanding core body 1 bottom is connected with oil fuel tube, and oil fuel tube is provided with butterfly valve 4.Oil level indicator board 6 is connected with ripple expanding core body 1, and along with the ripple core body is flexible up and down, indicator board also raises along with core body or reduces, highly sensitive, can see that oil level changes by the observation window 7 be contained on outer protective cover, intuitive and reliable.And warning device---the travel switch that monitors the oil level height is housed on outer protective cover, can meets unwatched needs.
Core body protective valve 2 is housed on blast pipe.It can delay the impact because in transformer, oil pressure unexpected increase of moment causes the oil storage cabinet.When having reached the core body limit, core body produces and breaks, and transformer body is protected in release, thereby has increased the transformer reliability of operation.This function is that the oil conservator of other type does not have.
The ripple expanding core body is made by stainless steel, and material is 1Cr18Ni9Ti.
Above-described the utility model execution mode, do not form the restriction to the utility model protection range.Any modification of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in claim protection range of the present utility model.
