Performance and main parameters of common metal composites, various welding processes and machinery and equipment, preparation treatment of thick steel plate, blanking process, production and manufacturing process and quality standards of automobile oil tank, riser,Santa Cruz de yoaTransformer box type transformer, coupling and oil storage tank cabinet, welding leakage test and NDT technology, surface treatment process and quality standards, copper, Production process and quality standard of aluminum shield; Body suit iron insertion process, wire installation process, body dryness solution and dry transformer oil solution process, vacuum pump oil immersion, general installation process, leakage test and leakage detection process and quality standards. Performance parameters of key work clothes, machinery and equipment of each process flow; The natural working environment is basically regulated.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.Santa Cruz de yoa,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.In the case of using dry-type transformer,Santa Cruz de yoaHigh frequency power transformer, customers must master the method of wiring. If there are problems in wiring, it is easy to cause common faults in application. So, what is the wiring mode of dry-type transformer?Bilina Kyselka,Dry type transformer companyAccording to the condition of cracks, galvanized iron wire can be punched into the leakage or riveted with hammer. Then clean the leakage point with toluene and seal it with raw materials. Coated sand casting eyes can be sealed with raw materials immediately.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,Santa Cruz de yoaOverload capacity and time of oil immersed transformer, and most application places leading to fire accidents are easy to choose in large and medium-sized engineering buildings and multi-storey buildings;

Avoid the load operation of power transformer: if the load operation is long-term, slow aging of insulation, short circuit fault between boxes, two-color short circuit fault or short circuit to ground fault and dissolution of oil.The iron loss of transformer includes two levels. The first is the hysteresis loss introduced by the transformer manufacturer. When the AC circuit is based on the transformer, according to the magnetic induction line of the transformer ferrite core, its orientation and size change with the change, which promotes the internal molecular structure of the ferrite core to interact with each other, releases energy, and then loses part of electromagnetic energy, which is the hysteresis loss. The other is the vortex loss when the transformer is working.The key reason for oil leakage is that there are defects in cast iron partsThe cost is reasonable,Sound in case of phase failureDuring no-load test run, the transformer shall be connected with the working voltage from the switching power supply side, and then make the working voltage impulse closing.After the oil is drained, all anchor bolts of the automobile oil tank at the upper end of the detachable oil cover shall be tied with the lifting jack, and the lifting point shall be on the common earrings or bolts. If necessary, the human resources traction belt shall be used as a guide.

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.Interpretation and observation,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 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 main body and accessories of the transformer are all normal and the transformer will turn to all normal operation.Santa Cruz de yoa, the resistance value exceeds m ohm bus.It is generally made due to unreasonable installation or ineffective sealing. Polymer composite materials can bond metal materials& 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, porcelain, laminated glass and other materials very well, so as to achieve the pressure management of oil leakage.It will also produce many faults effectively deal with various faults of oil immersed transformer, make full use of the performance indicators and advantages of oil immersed transformer, and continuously improve the safety factor of oil immersed transformer. Ignition is a common fault of oil immersed transformer. The key fault of oil immersed transformer is short-circuit fault, and short-circuit fault is more general.
