When checking the hook core, the insulation of the electromagnetic coil and the porcelain sleeve is usually accidentally damaged. After the shell of the pottery is broken, if you work again, turn on the photo flash when it's light, and it's short when it's heavy. Therefore, please pay attention during maintenance. It is not necessary to destroy the insulation. After maintenance, experts can inspect special tools, parts, insulation,BoskaParameters of 500 KVA oil immersed transformer, etc. and deliver them after they are determined to be complete and reliable.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.Boska,It should be said that after the development trend of these years the overall level of China's transformer industry at this stage is basically international, and the quality level is no different from that of overseas goods& rdquo; The person in charge of the transformer Federation of China Household Appliance Industry Association said.Noise solution of dry-type transformerSivednica, 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.Transformer manufacturers generally adopt IP protective casing, which can avoid the entry of solid dirt with a diameter of more than mm, rats snakes, cats, birds and other animals, resulting in vicious common faults such as short-circuit fault and power failure,BoskaMaintenance of oil immersed transformer, IP protective casing can be adopted, IP casing will reduce the refrigeration capacity of the transformer, so pay attention to the reduction of its operating volume.(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, and a warning sign shall be hung at a prominent position.equipment maintenance ,The 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, bind the laminated glass stopper firmly with clean paper or cloth to prevent dirt and water from contaminating the bottle stopper.Before no-load impact closing, the pose period of overcurrent protection shall be set to zero, and the data signal circuit of steam vehicle relay shall be temporarily connected to the pull-in circuit.

The project cost is different. Compared with the purchase price of capacity transformer, the purchase price of dry-type transformer is much higher than that of oil immersed transformer.Sincere service,Gradually,BoskaS11 technical parameters of power transformer, high-frequency vibration damping mechanical equipment, such as low-frequency vibration damping platform, is installed at the bottom of the dry-type transformer, which can reduce the downward dispersion of the vibration of the dry-type transformer. Then replace the connection between the dry-type transformer and the surrounding engineering buildings, roads, etc. with flexible connection, or use elastic yellow shock absorption mechanical equipment to prevent the vibration from spreading according to the rigid connection. If possible, the dry-type transformer room can also be soundproofed and decorated and sound-absorbing plates and silencing shutters can be used to improve the soundproofing capacity of the dry-type transformer room.First of all, although dry-type transformer has strong moisture resistance, it is generally open structure or very susceptible to moisture, especially the insulation level of dry-type transformer manufactured in China is low (lower flame retardant grade) Therefore, the dry-type transformer can obtain high stability only when the air humidity is below %. The dry-type transformer shall also be prevented from stopping operation for a long time to prevent serious damp. When the grounding resistance value is less than / V (operating voltage), it indicates that the transformer is seriously damp, and the trial operation shall be terminated.How to reduce the failure of dry-type transformer?Boska,Dry type transformer companyThe vibration reduction of collecting and townhouse solves the soft connection of collecting and townhouse. For the copper bar of the low-voltage bus of the equipment, the electromagnetic induced noise oscillation may be transmitted from the townhouse to the building structure. The core of noise reduction solution must be changed to copper wire connection.(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, and a warning sign shall be hung at a prominent position.
