KesemakiWind power box transformerThe heat load test run of the rotary hearth furnace project was successful

According to the condition of cracks, galvanized iron wire can be punched into the leakage or riveted with hammer. Then clean the leakage point with toluene and seal it with raw materials. Coated sand casting eyes can be sealed with raw materials immediately.The voltage regulating tap changer is not in place or poorKesemaki,Under normal conditions, different oil-based oils cannot be mixed. Under special circumstances, 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.Noise dispersion of dry-type transformerSakhrah,The flange surface is uneven, the tightening bolts are loose and the installation and processing process is wrong, so that the bolts are not tightened well, resulting in oil leakage.The 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, the output capacity can be increased by %.The flange surface is uneven, the tightening bolts are loose, so that the bolts are not tightened well, resulting in oil leakage.

Oil leakage of bolt or pipe external threadThe insulation of the through core anchor bolt clamping the iron core is damaged, resulting in a short circuit fault between the silicon steel sheet of the iron core and the through core anchor bolt;High voltage fuse of transformer breaks one phase;indexWhen checking the hook core, the insulation of the electromagnetic coil and the porcelain sleeve is usually accidentally damaged. After the shell of the pottery is broken,Kesemaki35kV oil type transformer, if you work again, turn on the photo flash when it's light, and it's short when it's heavy. Therefore, please pay attention during maintenance. It is not necessary to destroy the insulation. After maintenance, experts can inspect special tools, parts, insulation, etc. and deliver them after they are determined to be complete and reliable.For example, in the s, the radio programs applied by every family in the countryside had a ground wire, and they were often wet with tap water. Protective grounding is to bury the copper plate of metal electrical conductor in the soil layer,KesemakiOil immersed transformer capacity, and then lead a point of it out of the road with transmission line, which completes the grounding protection. The grounding wire specifies the grounding wire resistance ≤ Ω. Grounding protection is a safeguard measure adopted to avoid safety accidents when using household appliances, it should be insulated before putting into use,KesemakiPrice of oil immersed transformer, and accurately measured with a V grounding megger. The insulation resistance from the primary side to the secondary side and the ground should be ^ mfl, the insulation resistance from the secondary side to the ground should be ^ mh, and the insulation resistance from the iron core to the ground should be & amp; gt; mfl (note that the grounding device piece should be removed).

Oil immersed transformer operationSupply chain quality management,Operation and maintenance management of oil immersed transformerOnce 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.Oil leakage of heat pipe radiatorKesemaki, the power transformer will be transported and sent to the power consuming machines and equipment. What is the zero line of the actual power transformer? Let's introduce it to us.Before no-load impulse closing, the transformer shall be placed for h and the rising seat and waterproof sleeve installed with vent plug shall be deflated on time.
