Description
Technical field
The utility model relates to a kind of transformer oil conservater, especially a kind of oil level gauge oil conservator.
Background technology
The transformer oil conservater will play the indication oil level, carry out the effect that oil degradation was breathed and prevented to oil under the product normal operation, can it is directly connected to transformer safely, stablely reach long-time running.
In existing middle low capacity, open type oil immersed power transformer structural design, the oil level indicator of institute's adapted oil conservater adopts plane oil meter or glass tubular type oil meter usually.In adopting plane oil meter structure indication oil conservater during oil level, because the normal oil colours of transformer is yellowish Transparent color, and aberration is less between the oil meter base plate, the rolling inspection personnel are difficult for from observing the transformer oil level at a distance, and transformer oil directly is subjected to can quickening oil deterioration after the effect of solar irradiation, and the insulating capacity of oil product is descended, and dielectric loss raises, to the corrosion of metal parts product, influence the heat radiation of heat generating components.When adopting glass tubular type oil meter, though red ball float is housed in the glass tube, the oil level indication is eye-catching, is convenient to the operation maintenance personnel and observes oil level, and is same because transformer oil is subjected to the effect of solar irradiation, easily makes oil colours deepen aging, quality badness.Simultaneously because glass tube and red ball float are very easily damaged, to having relatively high expectations of installation and transportation aspect.
Since in transformer plane oil meter and the glass tubular type oil meter oily all with oil conservater UNICOM, the ageing oil in the oil meter is easily sneaked in the oil conservater, even enters in the transformer body fuel tank, makes product electrical insulation properties deterioration.Transformer oil starvation and oil degradation all directly have influence on the safe operation of transformer.
The utility model content
The technical problems to be solved in the utility model is: be subjected to the solar light irradiation effect in order to overcome transformer oil, easily make oil colours deepen aging, quality badness, the insulating property of oil reduce, can not clearly observe the problems such as oil level of transformer, a kind of pointer type fuel level indicator oil conservater is provided, reduce transformer oil affair management workload, guarantee that product can the long-term safety operation.
The technical scheme that its technical matters that solves the utility model adopts is: have cabinet wall, base plate, cover plate, oil filler plug, oil sample valve, dehydrating breather, dehydrating breather connection pipe, be used to connect connecting pipe, support and the cabinet angle of oil conservater and transformer top cover, described cabinet wall is columnar structured, one end is welded with base plate, the other end is welded with cover plate, also has pointer type fuel level indicator, described pointer type fuel level indicator is installed on the cover board, and the fly rod on the pointer type fuel level indicator extend into the inside of oil conservater.
The mounting means of described pointer type fuel level indicator is to open a circular hole at the cover plate center, and is welded with the mounting flange that pointer type fuel level indicator is installed, and the screw on the mounting flange is a blind hole, outside full weld structure in mounting flange and cover plate are welded as.
Described pointer type fuel level indicator structure is disc type, Plane Installation structure, scale all adopts the visual paint spraying of noctilucence in the pointer of pointer type fuel level indicator and the dial plate, be equipped with on the fly rod and can change the float that drives the fly rod rotation, be milled with on the dial plate installed surface and supply the fixedly seal groove of usefulness of O-ring seal with oil level.Pointer is consistent with the fly rod yawing moment in the dial plate, and pointer indication dial scale is the height of oil level in the oil conservater.
When oil conservater was not installed gas relay, connecting pipe one end stretched into the cabinet wall, and the other end then is welded with joint flange, and connecting pipe is connected with the transformer top cover by joint flange, seal.、
When oil conservater is installed gas relay, connecting pipe is divided into bend pipe and following bend pipe, last bend pipe one end stretches into the cabinet wall, the other end then is welded with joint flange, be provided with butterfly valve between last bend pipe and gas relay, all there is joint flange at following bend pipe two ends, and an end is connected with gas relay, the other end is connected with the transformer top cover, and the junction is equipped with seal.
Employing of the present utility model is compared with the existing charged signal contact formula pointer type fuel level indicator in market, has simple and reliable for structurely, easy for installation, increases characteristics such as cost of goods manifactured, good economy performance hardly.Because this product is used in various lots of power supply-distribution system, is applicable to that diameter is the renewal of φ 180～φ 610mm oil conservater, thereby is the ideal substitute of existing plane oil meter and glass tubular type oil meter type oil conservater simultaneously.
The beneficial effects of the utility model are: the utility model adopts oil level gauge oil conservator, and transformer is not exposed under the sunshine, avoids light to the oil deterioration effect, delays the ager process of insulating oil; Oil conservater is equipped with dehydrating breather, can prevent that airborne moisture and dust etc. from entering oil conservater inside, guarantees that insulating oil keeps higher dielectric strength in the long time; Because the pointer type fuel level indicator indication obviously,, thereby guarantee that the transformer ' s type product can safe operation even also can clearly observe oil level at night.
