Abstract
The present invention relates to transformer oil conservator, and especially is a non-electrical signal connection point pointer type oil conservator of oil level indicator. The oil conservator has cabinet wall, soleplate, cover board, filling plug, oil sample shutter, water absorber, water absorber join tube and connecting pipe etc, the pointer type oil level indicator is mainly used, and is mounted on cover board, the rod float of pointer type oil level indicator extends into inside of oil conservator. The present invention adopts oil conservator of oil level indicator, which will not expose transformer oil to sunlight directly for avoiding oil ageing by light and delaying aging progress of insulating oil; at the same time with water absorber which can prevent moisture and dust, etc in air into inside of the oil conservator, assuring insulating oil maintaining higher insulating intensity in long period time; because pointer type oil level indicator is clear, which can observe the oil level clearly even if at night, thereby transformer products can operated safely.
Description
Technical field
The present invention relates to a kind of transformer oil conservator, especially a kind of no signal of telecommunication contact type oil level gauge oil conservator.
Background technology
The transformer oil conservator 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 conservator adopts plane oil meter or glass tubular type oil meter usually.In adopting plane oil meter structure indication oil conservator 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 conservator UNICOM, the ageing oil in the oil meter is easily sneaked in the oil conservator, 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.
Summary of the invention
During the technical problem to be solved in the present invention: provide a kind of and be subjected to the solar light irradiation effect in order to overcome transformer oil, easily make oil colours deepen aging, quality badness, the insulation property of oil reduce, can not clearly observe the problems such as oil level of transformer, a kind of oil level gauge oil conservator is provided, reduce transformer oil affair management workload, guarantee that product can the long-term safety operation.
The technical solution adopted for the present invention to solve the technical problems is: a kind of oil level gauge oil conservator has the cabinet wall, base plate, cover plate, oil filler plug, oil sample valve, dehydrating breather, dehydrating breather connection pipe, be used to connect the tube connector of oil conservator and transformer top cover, support and cabinet angle, 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, fly rod on the pointer type fuel level indicator extend into the inside of oil conservator, oil level indicator is not with high-low pressure oil level signal of telecommunication contact, and is simple and reliable for structure.
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, and scale all adopts the visual paint spraying of noctilucence in the pointer of pointer type fuel level indicator and the dial plate, is convenient to the distant surveillance oil level.Be equipped with on the oil level indicator 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 sealing ring 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 conservator.Plastic-blasting coating process, good weatherability are adopted in the oil level indicator surface.
When oil conservator was not installed Buchholz relay, tube connector one end stretched into the cabinet wall, and the other end then is welded with adpting flange, and tube connector is connected with the transformer top cover by adpting flange, seal.
When oil conservator is installed Buchholz relay, tube connector 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 adpting flange, be provided with butterfly valve between last bend pipe and Buchholz relay, all there is adpting flange at following bend pipe two ends, and an end is connected with Buchholz relay, the other end is connected with the transformer top cover, and the junction is equipped with seal.
Employing of the present invention 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 manufactured, 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 conservator, thereby is the ideal substitute of existing plane oil meter and glass tubular type oil meter type oil conservator simultaneously.
The invention has the beneficial effects as follows: the present invention adopts no signal of telecommunication contact finger pin type oil level gauge oil conservator, and transformer oil is not directly exposed under the sunlight, avoids light to the oil deterioration effect, delays the ager process of insulating oil; Oil conservator is equipped with dehydrating breather, can prevent that airborne moisture and dust etc. from entering oil conservator inside, guarantees that insulating oil keeps higher dielectric strength in the long time; Because the pointer type fuel level indicator indication obviously,, thereby guarantee the safe operation of transformer ' s type product energy even also can clearly observe oil level at night; When this product is used in 23 ° of tropic of north and south latitude with interior area, its anti-oil degradation and weatherability effect are particularly evident.
