Before and after sampling,PSV EindhovenWhat is the price of 1000 KVA transformer, clean the periphery of the sampling port with clean or hairless linen.The 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:PSV Eindhoven,Step up process of dry-type transformer?Wiring mode of dry-type transformer:Penaflor,Operation and maintenance management of oil immersed transformerIt will also produce many faults, make full use of the performance indicators and advantages of oil immersed transformer, and continuously improve the safety factor of oil immersed transformer. Ignition is a common fault of oil immersed transformer. The key fault of oil immersed transformer is short-circuit fault, and short-circuit fault is more general.The method and whole process of taking oil sample of power transformer are as follows:

The tail end of the high-voltage winding head and the middle tap are made of copper inserts and embedded parts, phase B and phase C respectively according to the color of yellow which is conducive to adjusting the data and has a unique and neat style.Precautions for trial operation of power transformer manufacturersThe input and output three-phase power lines shall be connected to phase a, green and red bus duct of transformer terminal board. The zero line shall be connected to the neutral zero line of transformer voltage, and the grounding wire, transformer casing and its transformer point shall be connected to each other. At ordinary times, the ground wire and zero wire are led out by the neutral wire of the transformer. (for example, the transformer box shall be matched with the ground wire mark of the shell and connected with each other). Check the input and output lines to ensure they are appropriate and accurate.Total quality management,Operation and maintenance management of oil immersed transformerHow to reduce the failure of dry-type transformer?Analysis of common faults of oil immersed transformer:

Noise dispersion of dry-type transformerExecutive standard,(II) the height width ratio of dry-type transformer pier installed on the ground is generally .m, and a guardrail of no less than m shall be installed around it,PSV EindhovenPrice of 200 KVA box type transformer, and a warning sign shall be hung at a prominent position.Precautions for trial operation of power transformer manufacturersThe 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.PSV EindhovenThe flange surface is uneven, the tightening bolts are loose, and the installation and processing process is wrong, so that the bolts are not tightened well, resulting in oil leakage.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.Sound in case of phase failure
