Hel BrownPrice of 200 KVA transformerHow to maintain quality issues

Dry type transformer companyHigh voltage fuse of transformer breaks one phase;Hel Brown,Hel BrownTransformer three-phase transformer,Visual inspection method for transformer inspectionThe 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, resistance to short-circuit faults, common faults and impact. The work is diligent.Larmani hat,When sampling from a small and medium-sized power transformer without a discharge pipe (or oil sample suspension plate), it can be in a power transformer such as a glass test tube when it is not in operation to extract the oil sample at the bottom, or it can be replaced by changing the oil.The 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.Before no-load impact closing, the pose period of overcurrent protection shall be set to zero, generally, the sealing of box edge and machine cover is sealed with acid-base resistant rubber rod or rubber plate. If the joint is not solved well, it will lead to common faults of oil leakage.How to select dry-type transformerAvoid the load operation of power transformer: if the load operation is long-term, short circuit fault between boxes, two-color short circuit fault or short circuit to ground fault and dissolution of oil.Honest managementSeal oil leakageBefore 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.Power transformer is an idealized supporting facility transformer for medium cabinet and high-voltage cabinet at the present stage, and can be equipped with safety protective casing according to different waterproof grades. It is applicable to key or unique natural environment sites such as multi-storey buildings, commerce, airports, tunnel construction, chemical enterprises and factories.

Caused by sand holes and cracks. For crack leakage drilling stop hole is a good way to remove in-situ stress and prevent widening.Design brand,Plug in the power with full load first, observe and detect that the input and output voltage meets the regulations. At the same time, check whether the equipment has abnormal sound, ignition,Hel BrownSpecification and model of dry-type power transformer, odor and other abnormal conditions. If there is any abnormality, please cut off the input switching power supply.How to make up oil for oil immersed transformer?When the full load test is carried out and everything is normal, the load can be connected.Hel Brown,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.In order to better reduce the probability of short-circuit fault of relay protection dry-type transformer, prevention and key are & ldquo; Prevention and Manipulation & rdquo; Is dominant.After sampling, bind the laminated glass stopper firmly with clean paper or cloth to prevent dirt and water from contaminating the bottle stopper.
