LanzhouWarranty period of oil immersed transformerSeveral common treatment methods for maintaining passivation

Before no-load impact closing, the pose period of overcurrent protection shall be set to zero,For oil transformer oil replenishment, unused transformer oil conforming to the new standard should be selected first. In addition,LanzhouHow much is a 100 KVA power transformer, the oil with the same basic, same brand and same additive type is expected to have a stronger effect. The characteristics of the oil should not be lower than that of the oil in mechanical equipment. When the new remaining oil is less than %, there is generally no problem. However, if there is more new remaining oil, oil shall be added before oil type Chromatographic analysis and pressure test shall be carried out to establish that there is no oil stain,Lanzhou160KV oil immersed transformer, and the acid value and dielectric loss shall not exceed the oil in the machinery and equipment.Dry type transformerBonoua,The power transformer conductor refers to the connecting transmission line between each electromagnetic coil, between the electromagnetic coil and the group outlet pipe and between the electromagnetic coil and the tap changer.Dry type transformer manufacturerIf the oil immersed transformer is burned by the cover of the transformer, when the oil immersed transformer fails, open the lower side of the transformer and place an appropriate part. When the oil immersed transformer is on fire the oil cannot be released to avoid the occurrence of the oil immersed transformer. At the same time, use detection equipment to put out the fire immediately. In order not to expand the hazard, the fire brigade must be notified.

Manufacturing process and steps of dry-type transformerThe equipment can eliminate the shortcomings found in the patrol inspection, clean the porcelain waterproof casing casing, remove and replace the cracked or brittle leather pad, check and tighten the node, replenish the oil with less oil, etc.Oil immersed transformer companymarket,The representative mode of connection group of dry-type transformer is: English capital letters indicate the wiring on the primary side (or primary side), and English letters indicate the wiring on the secondary side (or secondary side). Y (or y) is star wiring, and D (or D) is triangular wiring.Before and after sampling, clean the periphery of the sampling port with clean or hairless linen.Dry type transformer manufacturer

Sound in case of phase failureWorkshop cost,LanzhouNational standard for oil immersed transformer,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.The insulation between silicon steel sheets is damaged, resulting in overheating and melting of the iron core;Dry type transformer manufacturerLanzhou,High voltage fuse of transformer breaks one phase;Avoid aging and damage of power transformer iron core insulation: aging of iron core insulation or damage of waterproof sleeve holding anchor bolt will cause large vortex of iron core, and long-term scalding of iron core will lead to insulation aging.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.
