The first step of the whole wave process calculation is to calculate the basic parameters of the Internet such as inductance， capacitance and resistor. The accuracy of those basic parameters does great harm to the calculation results of the whole wave process. For the inductance calculation， the good model is the solid model of infinite transformer core column， but there are many calculation methods.
Power transformer factory
PiroerburPower saving analysis of transformers has always been based on whether the utilization rate of transformer capacity is less than a certain standard value. Whether transformers are environmental protection and energy saving specifications. In fact， sometimes such specifications are not saving electromagnetic energy， but consuming electromagnetic energy.
Due to careless transportation of the transformer and the thin high-voltage conductor，PiroerburDry type transformer unit， the transformer was disconnected by vibration (but there was no grounding device).
North BridgeIn specific daily life， oil immersed transformers are released outward in the form of waves. This kind of wave is like a tide. It is also a kind of kinetic energy. In fact， the wave height of oil immersed transformer also shows the size of kinetic energy. Generally， computer automatic system is used to control the wavelength and frequency of electromagnetic wave. The longer the light wavelength is， the greater the output power is. On the contrary， capacitance and resistor. The accuracy of those basic parameters does great harm to the calculation results of the whole wave process. For the inductance calculation， the good model is the solid model of infinite transformer core column， but there are many calculation methods.

Before and after sampling，PiroerburIs there a transformer in the distribution room， clean the periphery of the sampling port with clean or hairless linen.
Transformer manufacturers said that at this stage， China"s energy-saving distribution transformer market is relatively scattered， coupled with the constraints of factors such as low threshold in the field， uneven companies，PiroerburParameters of 10kV distribution transformer， lack of evaluation and specifications， and inadequate technical innovation， resulting in slow marketing of energy-saving transformers.
There are also many problems to pay attention to in the preventive measures and process of dry-type transformer damping. What are the key effects and functions of dry-type transformer damping and the corresponding preventive measures? Let"s master and consult in detail with the small editor of the dry-type transformer manufacturer.
Installation requirementsThe clock expression is used to indicate the phase difference correlation of the working voltage of the secondary side line. The phasor of the working voltage of the primary side line is used as the minute hand， the fixed finger is at o"clock， and the phasor of the phase voltage of the secondary side is used as the second hand.
Fault judgment of power transformer
The oil in the machinery and equipment of the oil storage tank shall generally stand for more than h before sampling; it is not necessary to stand when sampling on the running power transformer.
When the transformer is put into operation， if the tap changer is not in time a great & ldquo; Tweet & rdquo; The high-voltage fuse is broken when the noise is serious; If the tap changer is defective， it will cause mild & ldquo; Squeak & rdquo; Corona discharge sound， once the load increases， it is likely to burn the circuit breaker of the tap changer. In case of such situation power off immediately for maintenance.
Convenient and efficientPower transformers are used in all walks of life
How to make up oil for oil immersed transformer?
The oil in the machinery and equipment of the oil storage tank shall generally stand for more than h before sampling; it is not necessary to stand when sampling on the running power transformer.
PiroerburThe 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.
Before application， the sampling container shall be cleaned with vehicle gasoline， soapy water or other organic solvents (such as trisodium phosphate) except oil stains， and then washed with tap water until it is not alkaline， and the water can be evenly distributed from the bottle， clearly put forward the glass test tube the bottle cap shall be tightly closed and cannot be opened before application.
Then clamp the branch pipe with your thumb， rotate and release the oil in the tube to clean the sampling tube， carry out it twice， and then draw the oil sample.
