The main reason is that the welding quality of electric welding is poor, there are empty welding, open welding, needle holes, and the potential safety hazards are exposed after operation. In addition, the electromagnetic induction vibration will crack the electric welding and lead to leakage.In the whole process of transmitting electromagnetic energy in the power supply system, the voltage loss is inversely proportional to the voltage, and the output power loss is inversely proportional to the square meter of voltage. The transformer is used to increase the voltage and reduce the closing damage.San Jose,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;In the case of using dry-type transformer, customers must master the method of wiring. If there are problems in wiring, it is easy to cause common faults in application. So,San JoseWarranty period of oil immersed transformer, what is the wiring mode of dry-type transformer?FierCifci,After the test, connect the data signal contact of the automobile relay with the alarm circuit,San JoseType of power transformer, the pull-in contact with the opening circuit, and adjust the overcurrent protection value.What about oil immersed transformer fire?Fault judgment of power transformer

Dry type transformerThe fundamental reason for this kind of inaccuracy is that when the transformer & ldquo; Dalar trolley & rdquo; is considered according to the size of capacity utilization rate, the high-capacity transformer must be replaced by the small-capacity transformer with high utilization rate, and then the iron loss is considered and the copper loss is ignored. In fact, for a certain load, the active power loss of small capacity exceeds that of large capacity The active power loss of the transformer, so it consumes electromagnetic energy.Noise pollution control and prevention measures of dry-type transformerStandard requirements,In specific daily life,San JoseHigh overload capacity distribution transformer, we have a certain understanding of the optical wavelength of oil immersed transformer. What kind of function does it have for transformer?Oil leakage at looper flangeWhen sampling from a small and medium-sized power transformer without a discharge pipe (or oil sample suspension plate), it can be in a power transformer such as a glass test tube when it is not in operation to extract the oil sample at the bottom, or it can be replaced by changing the oil.

The noise of dry-type transformer is mainly the vibration noise in operation. This vibration noise is caused by multiple positions including the vibration of magnetic induction electromagnetic coil. All pay great attention to the solution of vibration when carrying out noise control.Total quality management,The noise of dry-type transformer is mainly the vibration noise in operation. This vibration noise is caused by multiple positions including the vibration of magnetic induction electromagnetic coil. All pay great attention to the solution of vibration when carrying out noise control.Power saving analysis of transformerThe key reason for oil leakage is that there are defects in cast iron partsSan Jose,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.The heat discharge pipe of heat pipe radiator is generally made of slotted seamless steel pipe after flattening by stamping die. When the heat discharge pipe is bent and welded by electric welding, oil leakage is often caused. This is due to the supporting force on the surface of the pipe and the working pressure on the inner cavity when stamping the heat discharge pipe.In relay protection dry-type transformer, the disconnection of the fault point is related to each other. In a word, if there is any problem at a certain point, it will affect the whole power circuit
