Abstract
The utility model relates to an on-line detecting and treating device for transformer oil, which is mainly composed of a sensor (1), a frequency converter (2), a microcomputer (3), an on-line oil treatment device (4), a display screen and an alarm unit (5), wherein, the sensor (1) is installed on the wall of a transformer (B) and connected with the microcomputer (3) by conducting wires, and an oil inlet pipe (401) and an oil outlet pipe (402) of the online oil treatment device (4) are connected to an inner cavity of the transformer (B). With the on-line testing and treating device for transformer oil, the insulating strength of the transformer oil can be automatically detected under the condition of no power cut and no machine halt, the transformer oil can be automatically treated so as to remove the moisture and impurity in the transformer oil, which can avoid the inconvenience of using a heavy detection device, and can prevent economic loss due to the power cut that causes a factory to stop production.
Description
The utility model relates to pick-up unit, particularly the online detection and the treating apparatus of transformer oil.
In oil-immersed type transformer, be filled with transformer oil, be used for Cooling Heat Transfer and improve insulativity, and play isolation, prevent the effect that air and moisture enter.Contain moisture and oxygen in the air of suction transformer, oxidation and humidity degenerate oil, acid and residue occur, immerse the aging and decomposition of insulating material fiber in the oil, also can produce moisture and residue, and consequently dielectric strength reduces, withstand voltage properties decline.
The transformer oil specific inductive capacity is represented its dielectric strength, but directly detect specific inductive capacity because the equipment heaviness, general unit can't use, therefore the dielectric strength to transformer oil is represented with voltage breakdown (KV/mm) in the prior art, and the newness degree of oil is represented with dielectric loss tangent tag δ, but the equipment of measuring voltage breakdown and dielectric loss tangent is also relatively heavier, and operating aspect has danger.
High-power transformer can not be changed oil easily, a collection of plant downtime will be caused because change oil, withstand voltage 35KV/2.5mm when transformer oil dispatches from the factory, when sucking moisture 0.01%, withstand voltagely drop to original 1/8, tag δ weighs transformer oil twisting and caused current loss of displacement because of some molecule in the medium in alternating electric field, the electric current of loss becomes heat energy and can cause oily temperature rise, therefore the antioxygenic property to transformer oil has higher requirement, to the moisture in the transformer oil, residue, colloid, naphthenic acid, acid sludge, sulfonic acid, trace solvents etc. all be should give removal, be to take the method that has a power failure in the prior art, this transformer is quit work, and then renew oil more, the front has been addressed and changed oil causing a collection of plant downtime, and is very uneconomical.
The purpose of this utility model is at the specific inductive capacity of the measuring transformer oil that exists in the above-mentioned prior art or voltage breakdown equipment heaviness, general unit can't use, and has danger, stopping production is changed oil and the problem of aspect such as very uneconomical, and online detection of a kind of transformer oil and treating apparatus are provided.
The purpose of this utility model is achieved through the following technical solutions:
Online detection of a kind of transformer oil and treating apparatus, mainly form by sensor (1), frequency converter (2), microcomputer (3), online oil treatment provisions (4) and display screen and warning device (5), sensor (1) is contained in the wall portion of transformer (B), and by lead and microcomputer (3) connection, the oil inlet pipe (401) of online oil treatment provisions (4) and flowline (402) are connected with the inner chamber of transformer (B).One end of the housing (101) of sensor (1) is equipped with pole plate, and heart position is provided with temperature compensation means (105) therein, has a cavity at the other end of housing (101), and adorn frequency converter (2) in this cavity.Said pole plate is a ring-type, also can be sheet.Plate filter and Shi Shi filtrator or centrifugal filter are housed in the online oil treatment provisions (4).
The utlity model has following advantage and effect:
Online detection of this transformer oil and treating apparatus can be under the non-stop-machine situation of not cutting off the power supply (medium) in the measuring transformer automatically, the dielectric strength of transformer oil, and the high repeatability of measuring accuracy is strong.
2. transformer oil can be handled and filter to online detection of this transformer oil and treating apparatus automatically under the non-stop-machine situation of not cutting off the power supply, and remove moisture and impurity in the oil.
Because above two have not only solved the inconvenience of the heavy checkout equipment of use in the prior art, and have exempted the trouble of cutting off the power supply shutdown and making plant downtime.
