In order to better carry out the experiment of power transformer oil, it is necessary to sample the power transformer oil. The sampling work should be carried out on a dry sunny day. The commonly used containers and sampling methods during sampling do immediate harm to whether the specific quality of the oil can be truly reflected. The oil sample for AC voltage withstand test shall not be less than .kg, and the oil sample for simplified experiment shall not be less than kg.Falling foreign matters and piercingSavonaThe 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 insulation layer of the dry-type transformer from penetrating due to overvoltage caused by overvoltage at the power grid side or lightning stroke on the line.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.Calabar,Use fiber materials to seal the bolts to achieve the goal of controlling leakage. The other is to screw out the bolt (nut) wipe the Fushi blue film remover on the surface, and then tighten it after wiping the raw materials on the surface. After drying, the treatment goal can be achieved.The tail end of the high-voltage winding head and the middle tap are made of copper inserts and embedded parts,SavonaRecycling power transformer, which is conducive to adjusting the data and has a unique and neat style.Method and process of taking oil sample of power transformer

Oil leakage at looper flangeDry type transformer, a static electrical equipment, is used to change the AC current (current) of a certain standard value into another or several types of working voltage (current) with the same frequency and different standard values. According to the supervision sampling inspection data of the third quarter of last year released by AQSIQ, among the kinds of dry-type transformer commodities manufactured by manufacturers in provinces and municipal districts across the country, kinds of commodities were found to be inconsistent with the provisions of relevant specifications, with a compliance rate of %& ldquo; This result mostly shows the quality level of China's dry-type transformer industry at the present stage.Dry type transformer companySincere service,Protective measures for damping of dry-type transformerInsulation and heat removal are different. Dry type transformers are generally insulated with epoxy resin, cooled by natural air and large capacity by centrifugal fan. Oil immersed transformers are insulated by insulating oil, and heat is discharged on the radiator (radiator) of the circulating system inside the transformer.After the test, connect the data signal contact of the automobile relay with the alarm circuit, the pull-in contact with the opening circuit, and adjust the overcurrent protection value.

The conductor insulation of power transformer is the main part of internal insulation. Some conductors should pass through the middle of electromagnetic coil,SavonaRecycling power transformer manufacturer, or between electromagnetic coil, iron yoke clamp and automobile oil tank wall. Therefore, it is necessary to ensure that this kind of conductor has sufficient insulation compressive strength, i.e. insulation spacing.Meticulous workmanship,Difference between dry-type transformer and oil immersed 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.After the test, connect the data signal contact of the automobile relay with the alarm circuit, the pull-in contact with the opening circuit, and adjust the overcurrent protection value.Savona,Dry type transformerThe noise of dry-type transformer comes fromOperation of oil immersed transformer
