When sampling from a small and medium-sized power transformer without a discharge pipe (or oil sample suspension plate), it can be in a power transformer such as a glass test tube when it is not in operation to extract the oil sample at the bottom, or it can be replaced by changing the oil.Protective measures for damping of dry-type transformerLatin America and the Caribbean,The equipment can eliminate the shortcomings found in the patrol inspection, clean the porcelain waterproof casing casing, remove and replace the cracked or brittle leather pad, check and tighten the node, replenish the oil with less oil, check and replace the silica gel of the breathing mask, etc.Fault judgment of power transformerSan Carlos,The capacity and working voltage are different. The dry-type transformer is generally suitable for distribution equipment. The capacity is generally below kVA and the working voltage is below KV, which also ensures the rated voltage of kV; Oil immersed transformers are generally suitable for distribution equipment.Power transformer is one of the key equipment in power station and substation. The function of power transformer is in all aspects. It can not only raise the voltage and send electromagnetic energy to the power consumption area,Latin America and the CaribbeanOil immersed transformer S13,Latin America and the CaribbeanOn load voltage regulating power transformer, but also reduce the voltage to each application voltage, so as to meet the needs of power consumption. In short, voltage transformation and blood pressure reduction must be carried out by the transformer.In specific daily life, we have a certain understanding of the optical wavelength of oil immersed transformer. What kind of function does it have for transformer?

How much is the power transformerAt rated power, the ratio of output power to input power of transformer is called the efficiency of transformer, i.e. & ETA; Is the efficiency of the transformer; P is the input power and P is the output power.After hours of continuous trial operation with a certain load the main body and accessories of the transformer are all normal, and the transformer will turn to all normal operation.Let's see,Oil leakage of porcelain pot and laminated glass oil level gaugeThe noise of dry-type transformer comes fromAfter no-load test run is normal for h, it can be transferred to on-load operation, and the load shall be gradually increased from %,Latin America and the CaribbeanPeriodic voltage regulator for maintenance of oil immersed transformer, % and % by grade.

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, so as to reduce the electric field component intersecting with the insulating parts.install,For kVA power engineering transformer, plastic parts are selected in the middle of iron core, it can be transferred to on-load operationCommon problems of tap changer of power transformerAfter no-load test run is normal for h, and the load shall be gradually increased from %, % and % by grade.When the whole process of winding wave of oil immersed transformer is calculated by using the marking method, the winding of oil immersed transformer is generally divided into multiple modules, and each module is replaced by an equivalent circuit, and its power circuit includes an inductance and vertical capacitance, a capacitance to ground or capacitance between windings, They also have mutual inductors between the inductors of each module
