Background technology
High-power transformer generally uses oil-filled transformer at present, main accessories of the conservator as oil-filled transformer, uses
In the storage reason such as transformer oil, the change of operating load or environment temperature transformer oil is expanded with heat and contract with cold, i.e., when temperature liter
Gao Shi, oil volume expansion, the oil level of conservator increase；Temperature reduces (load decline), oily volume-diminished, the oil level of conservator
Decline therewith, conservator makes the fuel head of transformer body and critical piece change in prescribed limit, so as to ensure transformer
Fuel tank internal keeps barotropic state substantially, it is ensured that equipment normal safe operation, operation maintenance personnel will observe installation for transformer oil closely
The situation of position, if the oil level of conservator is abnormal, illustrate that inside transformer there may be abnormal conditions.
Because transformer oil level is significant to transformer normal operation, usual installation for transformer is equipped with different surveys
Measure the oil level indicator of principle, such as common magnetic needle oil level indicator now, principle be when oil level changes, ball float with oil level above and below
Float, indicated on dial transformer oil level with pointer by mechanisms such as connecting rod, travelling gear, magnet, oil level indicator
Scale be uniform, when transformer oil is to highest, minimum oil level in conservator, oil level indicator can send alarm signal.But
The restriction of oil level indicator measuring principle is limited by, device reliability, accuracy factor influence, and oil level indicator often can not truly reflect storage
Actual oil level in Oil Tank, there have been " false oil level " phenomenon for this.
The reason for emerged in operation vacation pasta, may have：Oil ga(u)ge blockage, respirator block, oil level gauge ball float is wrongly installed, thick stick
Bar fractures, oil-feed etc. in ball float., can be by infrared imaging diagnostic techniques, oil pressure measurement etc. indirectly when there is false oil level situation
Means are judged and estimated to oil pillow oil level, but the above method is by many-sided system such as environmental factor, measuring instrument accuracy
About, often can not accurate measurement to actual oil level, can not sometimes or even at all judge oil level position.Now must be by transformation
Device is stopped transport, and is taken direct measuring method to detect oil level, this method operating time length, complex steps, is added operation of power networks
Risk, also to loss can be brought to the economy of operation of power networks.
