Visual inspection method for transformer inspection

8The insulation of the through core anchor bolt clamping the iron core is damaged, 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.

WIsraelAccurately measure the resistance of each phase winding and carry out the measurement. If there is a great difference, it is a common fault of the winding. Then carry out the appearance inspection of the iron core,Product display and then accurately measure the inter chip insulation resistor by AC voltage and galvanometer method. If the damage is not large,OstrovType of dry-type transformerThe classification details paint the damaged part.

OpIf the input of dry-type transformer is an alternating switching power supply, its output voltage is directly proportional to the coil turn ratio of the output input solenoid coil. If a rechargeable battery is used, because it is DC, add a circuit in the input power supply circuit to change it into a continuously changing voltage. In that way, the alternating DC current can be obtained at the output end.

The top and middle of the transformer oil tank, the flange plate, barrel skin and the middle of the waterproof sleeve at the upper end of the automobile oil tank. The internal iron core and winding clamp are hot due to partial magnetic leakage, resulting in insulation damage.

When the operating oil is mixed with different types of new oil or used for oil, in addition to the accurate measurement of the cold filter point of the mixed oil,Product display it is also necessary to carry out high and low temperature test and sludge test and observe the sludge accumulation. The accumulation cannot be accessed. The results of the operation of the mixing template are not that the original oil is very poor, so it can be managed and used in a mixed manner.

xAfter tightening the loose bolts, seal the flange, and solve the bolts that are likely to leak, so as to achieve the goal of complete treatment. Tighten the loose bolts strictly according to the actual operation and processing technology.

HThe dry-type transformer used for power plant voltage transformation is different from the oil transformer. It is strictly prohibited to lead the way at the bottom voltage side to prevent the transmission overvoltage caused by overvoltage at the power grid side or lightning stroke from penetrating the insulation layer of the dry-type transformer.

TVariable costThe common dry-type transformer is an important electrical equipment, and the voltage is constantly regulated. However, because of certain necessity, the dry-type transformer will also boost voltage, and the whole process of boosting voltage is very complex, and there are many principles.

In fact,Product display apart from the application of the Finance Bureau, the industry has been trying to formulate and upgrade transformer commodities according to the specifications so as to promote the improvement of energy consumption level of transformer commodities.

Marketing DepartmentsHow is the quality level of dry-type transformer compared with foreign countries?

FThe power transformer belongs to relatively durable electrical equipment,OstrovType of dry-type transformerThe classification details and we cant neglect it in daily application. The common problems of power transformer conductor, power transformer winding and power transformer tapping power switch are analyzed below:

eLakovnikUnder normal conditions, if it is necessary to use new oil of different grades, it should be determined whether the mixed oil with ice degree can be used according to the requirements of the region, and then the oil mixing test should be carried out.

oJAccording to the introduction of transformer manufacturers, the capacity utilization rate is only about %, After replacing one kva small transformer the utilization rate is close, but the main parameters of the two transformers are evaluated as shown in Table . Table evaluates the main parameters of the transformer: capacity (VA) iron loss (W) copper loss (W). Firstly,Power transformer price: 1000KVA, 33kV power transformer, 25kV power transformer, power transformer, oil immersed transformer, dry-type transformer factory the output power is saved according to the customary calculation method (ignoring copper loss): the results show that the loss of large capacity transformer is lower than that of small capacity transformer, It actually consumes electromagnetic energy.
