S11-10KV oil immersed transformer no-load test and load test can be simplified to measure current, under the specific conditions of voltage and power. Method for measuring these electrical parameters are analog circuit method and the calculation method of sampling. Although analog circuit measurement method of high accuracy, good stability, but is not suitable for the multi parameter measurement. According to certain rules of the instantaneous value of the measured signal sampling method of AC sampling, numerical algorithm and then obtain certain measured. The measurement can be completed various parameters of the same hardware use different algorithms to program, but also reduces the volume of the instrument.
Closely related to compaction condition, vibration and 10KV oil immersed transformer windings and iron core S11-10KV oil immersed transformer oil tank surface displacement and deformation state, so it can be to monitor the situation through the winding and iron core vibration signal on-line measurement of oil tank surface. The electromagnetic field analysis: analysis software using electromagnetic field, analysis of DT in transient field and the spatial magnetic eddy current field distribution, and calculate the corresponding output characteristics. Analysis of cross interference: according to the electromagnetic interference exists between the redundant sensors, computing cross interference between DT. Analysis of thermal field: the spatial distribution of magnetic field based sensor, temperature distribution caused by environmental temperature and the self heating stability calculation of thermal field, sensor temperature distribution and environment temperature of unsteady heat field and the self heating induced. The tolerance analysis: in the constant electromagnetic field, analysis of the influence of the sensor size, material properties change of output characteristics of its, in order to these parameters in the design stage to control, improve product reliability. Stress analysis: the structure due to the thermal stress, the random vibration stress, caused by relative position of winding and parts of the change of magnetic properties of materials change, analysis of the impact of these changes on the DT output characteristics.
To so e the oil immersed type 10KV oil immersed transformer oil leakage problem, as a means of increasing the competitive strength of the product. In recent years, many domestic electric power department and 10KV oil immersed transformer manufacturing plants are very concerned about the development and selection of rubber seal products, and the rubber sealing products manufacturer in order to meet the needs of the development of 10KV oil immersed transformer have developed various series of rubber sealing products. Currently on the market the emergence of various rubber varieties, there are also a variety of its quality statement. According to many years of research experience, the use of verification and technical achievements, this on the advantages and disadvantages of various rubber and the scope of use are analyzed, in order to provide basis and reference for the 10KV oil immersed transformer, transformer, switch manufacturing department to choose proper sealing products.
