VasluDry type transformer controllerAnalysis of the cause of abnormal noise

When using the oil sample of the power transformer in operation, it is necessary to add some oil from the oil gate valve at the lower part of the oil tank or the sampling gate valve to release about kg of waste liquid stored at the bottom to clean the oil inlet, and then take the oil sample.kV and above & plusmn; No load of rated voltage; Part of the circuit breaker of the tap power switch is installed in the phenolic resin insulating paper cylinder, and the insulating paper cylinder is installed on the wooden frame. The actual operation rocker is connected with the dynamic circuit breaker of the tap power switch according to the wooden insulating rod. The on load tap off power switch is insulated from the ground by the insulating paper cylinder of the power switch itself and the insulating limit.Vaslu,Accurately measure the resistance of each phase winding and carry out the measurement. If there is a great difference, it is a common fault of the winding. Then carry out the appearance inspection of the iron core, and then accurately measure the inter chip insulation resistor by AC voltage and galvanometer method. If the damage is not large, paint the damaged part.Noise pollution control and prevention measures of dry-type transformerSadiqabad,Power transformer manufacturerPower transformer manufacturerSome are tied with plastic tape, and some immediately press the two edges together, because the socket can not be pressed firmly during installation, and there is still oil leakage without sealing effect.

The tail end of the high-voltage winding head and the middle tap are made of copper inserts and embedded parts, with good strength and stiffness, dry-type transformers mostly use silica gel waterproof casing, while oil transformers mostly use porcelain waterproof casing;Quality inspection report,Then clamp the branch pipe with your thumb, clearly put forward the glass test tube, rotate and release the oil in the tube to clean the sampling tube, carry out it twice,VasluElectric box transformer, and then draw the oil sample.Before and after sampling, clean the periphery of the sampling port with clean or hairless linen.When oil samples are used the safety and fire safety technical specifications on the spot shall be strictly implemented.

Turn off the gate valve (butterfly valve) of the left and right tablet computers of the heat pipe radiator to isolate the oil in the heat pipe radiator from the oil in the tank, so as to reduce the working pressure and leakage. After the leakage location is determined, appropriate surface treatment shall be carried out, and then Fushi blue raw materials shall be selected for sealing treatment.Where can I find it?,VasluDry type transformer production video,For no-load impulse closing of transformer, pay attention to the following matters:In order to better avoid overvoltage damage, a group of overvoltage maintenance high-voltage Arresters (such as ycs active zinc oxide high-voltage arresters) shall be refitted at the working voltage bus duct side of dry-type transformer.When the full load test is carried out and everything is normal, the load can be connected.Vaslu, in the operation prevention and regulation of relay protection dry-type transformer, lock the fault point and analyze the short-circuit fault types of relay protection dry-type transformer. At the same time, if all fields are clear, disconnect the switching power supply at the fault point, the maintenance work of employees will be carried out smoothly, and the harm will not expand to a greater extent.The method and whole process of taking oil sample of power transformer are as follows:In 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, it is very small.
