When oil samples are used, the safety and fire safety technical specifications on the spot shall be strictly implemented.The noise of dry-type transformer is mainly the vibration noise in operation. This vibration noise is caused by multiple positions, including the vibration of magnetic induction electromagnetic coil. All pay great attention to the solution of vibration when carrying out noise control.Online ,Once the insulation material of electrical equipment is overheated, the surrounding gas will cause a kind of odor. This kind of odor can be sniffed out by normal patrol staff. When you smell such odor during normal inspection, you should carefully inspect the equipment and parts until you find out the cause.In relay protection dry-type transformer,Online Temperature protection of dry type transformer, the disconnection of the fault point is related to each other. In a word, if there is any problem at a certain point it will affect the whole power circuitArmenia,Dry type transformer manufacturerThe 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, and the phasor of the phase voltage of the secondary side is used as the second hand.(I) the distance between the external contour of kV and below dry-type transformer and the surrounding guardrail or courtyard wall shall take into account the convenience of transportation and repair of dry-type transformer,Online S13 power oil immersed transformer, and the distance shall not be less than m; At the angle with actual operation, a spacing of more than m shall be reserved; If metal fence is selected, the metal fence shall be grounded and a warning sign shall be hung at a prominent position.
After no-load test run is normal for h, it can be transferred to on-load operation, and the load shall be gradually increased from %, % and % by grade.There is a magnetic induction line crossing in the transformer core, which will cause induced electromotive force on the plan with the magnetic induction line. Because this electric flow creates a closed loop to generate an electric field and forms a vortex,Common problems of tap changer of power transformerThe 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 key reason for oil leakage is that there are defects in cast iron parts
Before no-load impulse closing, the transformer shall be placed for h, and the rising seat and waterproof sleeve installed with vent plug shall be deflated on time.recommend,After tightening the loose bolts, seal the flange, and solve the bolts that are likely to leak so as to achieve the goal of complete treatment. Tighten the loose bolts strictly according to the actual operation and processing technology.Under normal conditions, different oil-based oils cannot be mixed. Under special circumstances, if it is necessary to use new oil of different grades it should be determined whether the mixed oil with ice degree can be used according to the requirements of the region, and then the oil mixing test should be carried out.Noise dispersion of dry-type transformerOnline ,Generally speaking, the ignition emergency treatment method of oil immersed transformer is mainly to disconnect the oil immersed transformer, disconnect the switching power supply on each side, quickly invest the reserved oil immersed transformer and start the power supply system from scratch. Stop the operation of refrigeration equipment. Key oil immersed transformer ignition. When L-type oil immersed transformer and high voltage station oil immersed transformer are ignited, plastic parts are selected in the middle of iron core, clamp and electromagnetic coil to keep the electromagnetic coil in a stable clamping state to reduce noise.The 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.
