Tokzar500 kV d
ArnhemThree phThe plastic shells of electrical products and office supplies are equipped with grounding wires. If the insulation layer is damaged and the shell is energized,TokzarPrice of 200 KVA box type transformer, the electric flow will leak into the earth along the installed grounding wires, so as to achieve the purpose of safety, otherwise it will have an adverse impact on life safety.
Oil immersed transformer
Tokzar.Transformer inspection nose sniffing method
When sampling in bulk gasoline barrels, samples shall be selected according to 5% of the number of gasoline barrels,TokzarPrice of oil immersed transformer, but not less than 2 barrels. When sampling in batches of small and medium-sized pails or bottles samples shall be taken according to 2% of the total number of barrels (bottles).
.Oil leakage of heat pipe radiator
The hanging core of dry-type transformer is a vital part
Then clamp the branch pipe with your thumb, clearly put forward the glass test tube, rotate and release the oil in the tube to clean the sampling tube, carry out it twice, and then draw the oil sample.
In the electric field of the winding to the yoke, there must be a strong line breaking component, so that sliding flash charge and discharge may occur at a lower current. In order to better solve this disadvantage, the appearance of the insulating parts between the winding and the iron yoke should be the same as that of the medium horizontal plane of the winding to the iron yoke insulation as far as possible, so as to reduce the electric field component intersecting with the insulating parts.
How to maintain dry-type transformer?

Loose core screw
In fact,TokzarOil immersed transformer manufacturer, ground wire is not only a kind of grounding protection. The following describes in detail that ground wire is the general name of grounding system. Ground wire is divided into protective grounding and safety factor grounding device. Among them, safety factor grounding device can be divided into grounding protection, anti electric shock grounding device and anti electromagnetic wave radiation grounding device. Protective grounding is to use it for loop to make the facilities achieve the grounding wire specified by the function.
Oil leakage of cast iron parts
Discount.After no-load test run is normal for 24h, it can be transferred to on-load operation, 50% and 75% by grade.
Maintenance contents of power transformer
In terms of the place of use, dry-type transformers are mostly used in & ldquo; Fireproof and explosion-proof type & rdquo; It is easy to use in large and medium-sized engineering buildings and multi-storey buildings; The oil immersed transformer because of & ldquo; Accident & rdquo; There is likely to be oil or leakage after fire, it will inevitably cause the loss of voltage and output power. When transporting the same output power, the voltage loss is inversely proportional to the voltage and the output power loss is inversely proportional to the square meter of voltage. The transformer is used to increase the voltage and reduce the closing damage.
