Oil leakage of cast iron partsThe 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.Neratovic,NeratovicHow much is a 250kVA box transformer,Once the insulation material of electrical equipment is overheated, the surrounding gas will cause a kind of odor. This kind of odor can be sniffed out by normal patrol staff. When you smell such odor during normal inspection, you should carefully inspect the equipment and parts until you find out the cause.What is the important role of power transformerArivonimamo,The 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.The bearing capacity of each load is different. Generally, dry-type transformer should operate under rated capacity, while oil transformer has better load working capacity.For the leakage that has already occurred find the leakage point first, which can not be ignored. For the position with serious leakage, the treatment surface shall be cleaned and tidy. Polymer composite materials are mostly selected for dry consolidation. After dry consolidation, the goal of long-term treatment of leakage can be achieved.

Operation of oil immersed transformerAt that time, only a few companies in China could produce kV high-voltage transformers, and the market share of high-voltage transformers was basically monopolized by overseas leaders.The noise of dry-type transformer belongs to low-frequency noise. In a small area,NeratovicStructure diagram of oil immersed power transformer, most of it is scattered according to the building structure. This kind of low-frequency noise is scattered to the household house according to the house building, and then causes gas vibration noise, which is then scattered to the ears of consumers. Although the amount of noise is not very large, the dispersion spacing and adverse effects are very large.technological innovation,When the power transformer operates at full load, it needs a large reactive load. This reactive load shall be provided by the power supply and distribution system. If the transformer volume is too large, it will not only increase the initial project investment, but also make the transformer operate at full load or load for a long time, expand the proportion of full load loss, reduce power factor and increase Internet loss. Such operation is neither economic development nor scientific.The hanging core of dry-type transformer is a vital partThe power transformer is designed according to the temperature protection scheme. The embedded parts in the material layer of high (low) pressure electromagnetic coil poured with integral concrete are provided with longitudinal ventilation duct, which can be equipped with air-cooled machinery and equipment (cooling centrifugal fan). After selecting air-cooled machinery and equipment,NeratovicVarious models of transformer, it is more and more unreliable. Ground wire (PE): it is not used as a working circuit, but only as a maintenance line. Use the affirmation of the earth & ldquo; ” Voltage. When the machine and equipment casing is electrified, the current will be quickly grounded. Even if there is a lead for the PE line, it will be grounded from the surrounding grounding body.analysis,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.Power saving analysis of transformerWhen the full load test is carried out and everything is normal, the load can be connected.Neratovic,The electromagnetic coil is wound with copper power wire or foil and lifted with glass fiber. The epoxy adhesive does not need filling. The vacuum drying equipment is used for degassing and dehumidification. The overall concrete is poured with high fracture toughness, resistance to short-circuit faults, common faults and impact. The work is diligent.In the whole process of transmitting electromagnetic energy in the power supply system, 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.(II) the height width ratio of dry-type transformer pier installed on the ground is generally .m, and a guardrail of no less than m shall be installed around it, and a warning sign shall be hung at a prominent position.
