The long-term overload of power transformer will slowly cause the scalding and insulation aging of solenoid coil, resulting in short circuit between coils,KamajuniParameter table of oil immersed transformer, two-color short circuit or short circuit on the ground, resulting in the ignition of power transformer. Therefore,KamajuniOil immersed transformer foundation, the insulation compressive strength of power transformer shall be tested before installation and operation, and overload is not allowed in the whole process of operation.It is generally made due to unreasonable installation or ineffective sealing. Polymer composite materials can bond metal materials, porcelain, so as to achieve the pressure management of oil leakage.Kamajuni,The 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;Manufacturing process and steps of dry-type transformerGoitapa,The vibration reduction of collecting and townhouse solves the soft connection of collecting and townhouse. For the copper bar of the low-voltage bus of the equipment, the electromagnetic induced noise oscillation may be transmitted from the townhouse to the building structure. The core of noise reduction solution must be changed to copper wire connection.The main reason is that the welding quality of electric welding is poor, there are empty welding open welding, sand holes and other shortcomings in welding. The oil transformer is easy to be covered with welding powder and paint when leaving the factory, and the potential safety hazards are exposed after operation. In addition, the electromagnetic induction vibration will crack the electric welding and lead to leakage.Insulation 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, insulated by insulating oil in the circulating system inside the transformer, and heat is discharged on the radiator (radiator) of the circulating system inside the transformer.

Oil immersed transformer companyThe transformer manufacturer shall not use hand touch method to detect energized high-voltage equipment such as transformer in operation and neutral grounding equipment of arc suppression coil. For the equipment without power supply and whose shell is reliable grounding device, the temperature or temperature rise must be tested by hand. The secondary equipment can be inspected by hand touch method when it is hot and vibrated.When the full load test is carried out and everything is normal, the load can be connected.discount,(IV) the transformer on the column shall be stable and firm, the transformer shall be connected with the working voltage from the switching power supply side, and then make the working voltage impulse closing.The main reason is that the welding quality of electric welding is poor, there are empty welding, open welding, needle holes, sand holes and other shortcomings in welding. The oil transformer is easy to be covered with welding powder and paint when leaving the factory, and the potential safety hazards are exposed after operation. In addition, the electromagnetic induction vibration will crack the electric welding and lead to leakage.

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, but also reduce the voltage to each application voltage, so as to meet the needs of power consumption. In short,KamajuniPrice of scb11 series dry type transformer, voltage transformation and blood pressure reduction must be carried out by the transformer.Honest management,What is the wiring mode of dry-type transformer?The 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.Dry type transformer companyKamajuni,Common problems of tap changer of power transformerMethod and process of taking oil sample of power transformerThe power transformer belongs to relatively durable electrical equipment, and we can't neglect it in daily application. The common problems of power transformer conductor, power transformer winding and power transformer tapping power switch are analyzed below:
