Oil immersed transformer operationThe insulation between silicon steel sheets is damaged, resulting in overheating and melting of the iron core;After no-load test run is normal for h, it can be transferred to on-load operation, and the load shall be gradually increased from %, % and % by grade.Installation requirements,The cross-sectional wiring of transformer input and output power plugs shall comply with the provisions of their current size; It should be equipped according to the current intensity of -A / Min.The key reason for oil leakage is that there are defects in cast iron partsAfter hours of continuous trial operation with a certain load, the main body and accessories of the transformer are all normal,LondonThree phase transformer 480v to 380V, and the transformer will turn to all normal operation.
Avoid the load operation of power transformer: if the load operation is long-term, it will lead to the scalding of solenoid coil, slow aging of insulation, short circuit fault between boxes, two-color short circuit fault or short circuit to ground fault and dissolution of oil.technological innovation,The power transformer conductor refers to the connecting transmission line between each electromagnetic coil, between the electromagnetic coil and the group outlet pipe, and between the electromagnetic coil and the tap changer.How to select dry-type transformerThe oil in the machinery and equipment of the oil storage tank shall generally stand for more than h before sampling; it is not necessary to stand when sampling on the running power transformer.London,Power transformer plantDry type transformer manufacturerPower transformer is an idealized supporting facility transformer for medium cabinet and high-voltage cabinet at the present stage and can be equipped with safety protective casing according to different waterproof grades. It is applicable to key or unique natural environment sites such as multi-storey buildings,LondonWhat is the allowable overload of dry-type transformer, airports commerce, tunnel construction, chemical enterprises and factories.
