When the transformer is put into operation, 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.After the test, connect the data signal contact of the automobile relay with the alarm circuit, and adjust the overcurrent protection value.Chatham Kent,At rated power the ratio of output power to input power of transformer is called the efficiency of transformer, i.e. & ETA; Is the efficiency of the transformer; P is the input power and P is the output power.When the transformer is out of phase, if the second phase is blocked, there is still no sound when the second phase is sent, and there is sound when the third phase is sent; If the third phase is blocked, the sound will not change,Chatham KentDry type transformer procurement, as in the case of the second phase. There are three reasons for phase deficiency:Usulutan,Chatham Kent10kV dry type transformer,What is the reason for the shutdown of power transformer?Careless maintenance and insulation damageDry type transformer manufacturer

The no-load impulse closing working voltage shall not exceed % of the working voltage marked on the gear of the transformer, the closing frequency shall be times, the delay time after power receiving shall not be less than min, and the time interval of each closing shall not be less than min.Hand touch method for transformer inspectionThe method and whole process of taking oil sample of power transformer are as follows:Executive standard,The technical specification of power consumption requires that the resistance of maintenance grounding wire shall be ≤ Ω, The resistor is generally more than & omega;, According to Ohm's law, when the insulating layer is damaged, the current is only / of the total current flow,Chatham KentLoss standard of dry type transformer, so as to play a guarantee effect. The higher the voltage, the smaller the resistance, in other words, in the case of high voltage. We can care about the power transformer plant and master a lot of professional knowledge.In the case of dry-type transformer operation, there is more noise, and some even cause noise which seriously endangers everyone's no problem rest time and work. At this time, the dry-type transformer needs sound insulation treatment. There are many processes and key methods to deal with the noise of the common dry-type transformer. How should the noise of the dry-type transformer be solved? Or with the dry-type transformer manufacturer's network editor to simply understand it.Oil leakage at electric welding position

On load commissioning:safety requirements ,Oil leakage of bolt or pipe external threadTransformer inspection nose sniffing methodNoise dispersion of dry-type transformerChatham Kent,What about oil immersed transformer fire?In the electric field of the winding to the yoke, there must be a strong line breaking component, so that sliding flash charge and discharge may occur at a lower current. In order to better solve this disadvantage, the appearance of the insulating parts between the winding and the iron yoke should be the same as that of the medium horizontal plane of the winding to the iron yoke insulation as far as possible, so as to reduce the electric field component intersecting with the insulating parts.Causes of fire in power transformer
