Abstract
The utility model is related to a kind of novel transformer oil level indicators, it is vertically arranged in transformer-cabinet top and is connected with the fuel tank in the transformer tank body, the oil level indicator includes oil storage column, display window is provided on the oil storage column side wall vertically, the display window is equipped with the oil float lifting pipe connected with the fuel tank in the transformer tank body.Advantageous effect：It is connected by oil storage column with transformer-cabinet, not only ensure that pasta higher than high-low pressure casing height, but also taken into account the characteristics of old-fashioned oil conservater compensation space is big；Overall structure is compact, not only ensure that basic function, but also greatly reduce appearance and size, saves space；Oil level shows that clear, compact-sized, more fuel-efficient, infrastructure cost greatly simplifies simultaneously.Using the structure of valve, prevent contact of the transformer oil with extraneous air, extend the service life of transformer oil.The place higher to transformer shape requirement especially suitable for box-type substation etc. significantly decreases the overall dimension and cost of equipment.
Description
Technical field
The utility model is related to transformer technology field, in particular to a kind of novel transformer oil level indicators.
Background technology
On transformer equipment at this stage, it usually needs use oil level indicator and oil conservater to complete the inspection to transformer oil
It surveys.Wherein oil level indicator is the principle using float, when transformer oil level changes；Float in oil tank of transformer with
One lifting of pasta drives the display device lifting in display window, instruction oil level variation；When transformer oil surface is less than fuel tank cap,
Without transformer oil in high-low pressure casing, the heat dissipation of high-low pressure conducting rod can be caused bad, easily cause conducting rod fever, oxidation etc.
Failure；Due to float long period of soaking, temperature of oil in transformer is up in eight or nine ten degree in deep fat, operation；Be easily deformed, cause clamping stagnation,
False oil level is formed, is caused a hidden trouble to equipment by original operation.Oil conservater is to increase one again on the basis of ontology fuel tank simultaneously
Auxiliary fuel tank for improving oil level, ensures in oil tank of transformer always full of oil；But in order to ensure arcing distance, oil conservater passes through
The mode of welding supporting leg extension is installed；Increase the size of transformer long axis direction in this way, cause volume increase, structure it is cumbersome,
The drawbacks such as material cost increase.Since oil conservater also needs to setting respirator so that transformer oil and outside air are unicom,
Long-play can cause transformer oil oxidation, make moist, and increase probability of failure, the deficiency of above-mentioned two existing equipment is ability
The urgent problem to be solved of field technique personnel.
Utility model content
In order to solve the above-mentioned technical problem the utility model provides a kind of novel transformer oil level indicator, with reference to old-fashioned oil level indicator
With being researched and developed the advantages of old-fashioned oil conservater, fuel head has not only been ensure that higher than high-low pressure casing height, but also taken into account old-fashioned storage
The characteristics of Oil Tank compensation space is big.
The utility model is achieved by the following technical solution：A kind of novel transformer oil level indicator, is vertically arranged in change
Depressor babinet top is simultaneously connected with the fuel tank in the transformer tank body, and the oil level indicator includes oil storage column, the oil storage column side
Display window is provided on wall vertically, the display window is equipped with the oil float lifting pipe connected with the fuel tank in the transformer tank body.
After adopting the above technical scheme, change old-fashioned oil level indicator structure and be arranged on oil storage column side wall, by traditional oil storage
Cabinet needs the mode for welding supporting leg to save, and is changed to oil storage column and is directly connected with the fuel tank in transformer tank body so that traditional oil storage
Cabinet accumulates and material greatly reduces.
Preferably, the oil storage column is the hollow tubular structure of top closure, the oil storage top end is equipped with air valve.
After above-mentioned preferred embodiment, it can prevent the transformer oil in oil storage column from directly being connected with outside air, because of length
Time operation can cause transformer oil to aoxidize, make moist.
The beneficial effects of the utility model are：It is connected by oil storage column with transformer-cabinet, both ensure that pasta higher than height
Low-tension bushing height, and taken into account the characteristics of old-fashioned oil conservater compensation space is big；Overall structure is compact, both ensure that basic training
Can, and appearance and size is greatly reduced, save space；Oil level shows clear, compact-sized, more fuel-efficient, infrastructure cost simultaneously
It greatly simplifies.Using the structure of valve, contact of the transformer oil with extraneous air is prevented, has extended the use of transformer oil
Service life.The place higher to transformer shape requirement especially suitable for box-type substation etc., significantly decreases the whole of equipment
Body appearance and size and cost.
Description of the drawings
The utility model will be further described below with reference to the accompanying drawings.
Fig. 1 is the overall structure diagram of the utility model；
Fig. 2 is enlarged diagram at A in Fig. 1；
Shown in figure：
1st, oil level indicator, 1.1, air valve, 1.2, display window, 1.3, oil float lifting pipe, 1.4, oil storage column, 2, transformer-cabinet.
Specific embodiment
In order to clarify the technical characteristics of the invention, this programme is explained with specific embodiment below in conjunction with the accompanying drawings
It states.
With reference to attached drawing 1-2, a kind of novel transformer oil level indicator specific embodiment：A kind of novel transformer oil level indicator erects
It is directly arranged on 2 top of transformer-cabinet and is connected with the fuel tank in the transformer-cabinet 2, the oil level indicator 1 includes oil storage column
1.4, transparency display window 1.2 is provided on 1.4 side wall of oil storage column vertically, the display window 1.2 is equipped with and the transformer
The oil float lifting pipe 1.3 of fuel tank connection in babinet 2,1.3 tube wall of oil float lifting pipe are marked in scale and pipe and are equipped with oil
It is floating.It changes old-fashioned oil level indicator structure and is arranged on 1.4 side wall of oil storage column, traditional oil conservater is needed to weld the mode of supporting leg
It saves, is changed to oil storage column 1.4 and is directly connected with the fuel tank in transformer-cabinet 2 so that traditional oil conservater volume and material are significantly
Reduce.
The oil storage column 1.4 is the hollow tubular structure of top closure, and 1.4 top of oil storage column is equipped with air valve 1.1.Energy
Enough prevent the transformer oil in oil storage column from directly being connected with outside air, because long-play can caused by transformer oil oxidation, by
Tide etc..
Certainly, above description is also not limited to the example above, and technical characteristic of the utility model without description can lead to
It crosses or realizes that details are not described herein using the prior art；Above example and attached drawing are merely to illustrate the technology of the utility model
It is limitation to the utility model that scheme, which is not, and Tathagata substitutes, the utility model only in conjunction with and with reference to preferred embodiment into
