When the new oil filled by the power transformer and the oil sample that has just been considered are used, the oil sample can be used only after sufficient standing.Analysis of common faults of oil immersed transformer:Enkoping ,The efficiency of transformer is closely related to the output power level of transformer. Generally the greater the output power, the smaller the loss to output power ratio and the higher the efficiency. On the contrary, the smaller the output power, the lower the efficiency.Manufacturing process and steps of dry-type transformerDalian,The 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.What about oil immersed transformer fire?For kVA power engineering transformer, plastic parts are selected in the middle of iron core, resulting in a short circuit fault between the silicon steel sheet of the iron core and the through core anchor bolt;Dry type transformeraverage methodOil leakage at looper flangeThe insulating layer shaft and the connecting articles between the bell jar and the core shall be removed. If it is a hanging bell inspection, the oil shall be pumped into the bottom of the bell jar before the bell jar can be removed.The iron core of power transformer is made of high-quality crystallized hot-rolled ferrite core, which is stacked at the degree fully inclined multi-step interface. The surface is covered with epoxy resin adhesive cable sheath coating, which is resistant to corrosion and rust, and has sound insulation and noise reduction.

The power transformer belongs to relatively durable electrical equipment,Enkoping Power supply transformer S11, 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:Encyclopedic knowledge,What is the reason for the shutdown of power transformer?The selection shall be carried out according to the load characteristics of power. There are many types of power loads. Different dry-type transformers shall be used for different power loads. If the standard impulse level of power load is less than kV, class H dry-type transformers shall be used. If the standard impulse level of power load exceeds kV, epoxy resin adhesive shall be used to pour dry-type transformers.For no-load impulse closing of transformer,It is generally made due to unreasonable installation or ineffective sealing. Polymer composite materials can bond metal materials, porcelain,Enkoping Price of 200KVA transformer, laminated glass and other materials very well, so as to achieve the pressure management of oil leakage.Dry type transformerThe 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.
