UrbiraBidding information of power transformerMaterial selection

After sampling bind the laminated glass stopper firmly with clean paper or cloth to prevent dirt and water from contaminating the bottle stopper.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.Urbira,Power transformer manufacturerFrom the appearance, the packaging types are different. The transformer core and electromagnetic coil can be seen immediately for dry-type transformer, and only the shell can be seen for oil immersed transformer;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, the generator set must be disassembled first.

Therefore, in the installation process of substation equipment, the lightning rod should be set according to the specific situation to prevent damage to the relay protection dry-type transformer caused by lightning. In addition, in the installation and use process of lightning rod, select reasonable types of lightning rod according to the operation situation to determine that they are in the same situation. In addition, during the installation of lightning rod, please connect all routes as far as possible to prevent other faults.The fundamental reason for this kind of inaccuracy is that when the transformer & ldquo; Dalar trolley & rdquo; is considered according to the size of capacity utilization rate, the high-capacity transformer must be replaced by the small-capacity transformer with high utilization rate, and then the iron loss is considered and the copper loss is ignored. In fact, for a certain load, the active power loss of small capacity exceeds that of large capacity The active power loss of the transformer,UrbiraEnergy efficiency class I oil immersed transformer, so it consumes electromagnetic energy.The dry-type transformer is composed of two winding resistances, Y & rdquo;, & ldquo; D Y & rdquo;, & ldquo; y, D & rdquo; and & ldquo; D, D & rdquo;. In China, only & ldquo; y, Y & rdquo; and & ldquo; y, D & rdquo; are selected. Because there are also two types of Y-connection with neutral line and without neutral line. If there is no neutral line, it will not be upgraded. All marks show that with neutral line, it will not be upgraded The letter N after the English letter Y indicates that the neutral line has transformer grounding wire. Yn wiring group, when UAB and UAB overlap, the minute hand points to . & ldquo; & rdquo; in the new wiring group, it is indicated by & ldquo; & rdquo.Bidding,& ldquo; of wiring transformer; Enter & rdquo; And & ldquo; Output & rdquo; Use a megger to test the grounding resistance between the terminal and the ground wire. When accurately measured by V megger, the resistance value exceeds m ohm bus.The electromagnetic coil is wound with copper power wire or foil and lifted with glass fiber. The epoxy adhesive does not need filling. The vacuum drying equipment is used for degassing and dehumidification. The overall concrete is poured with high fracture toughness,Urbira380V to 660V three-phase transformer, resistance to short-circuit faults, common faults and impact. The work is diligent.How to reduce the failure of dry-type transformer?

In terms of the place of use, dry-type transformers are mostly used in & ldquo; Fireproof and explosion-proof type & rdquo; It is easy to use in large and medium-sized engineering buildings and multi-storey buildings; The oil immersed transformer because of & ldquo; Accident & rdquo; There is likely to be oil or leakage after fire,Dry type transformer manufacturerTransformer inspection nose sniffing methodBefore no-load impact closing,UrbiraCommercial power transformer, 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.Urbira,Oil immersed transformerBefore 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.When we apply oil immersed transformer, we all know that it works with the help of oil. What if the oil immersed transformer is on fire? What countermeasures should we do?
