ZakapaDry type transformerPursue excellence

The tail end of the high-voltage winding head and the middle tap are made of copper inserts and embedded parts, with good strength and stiffness, which is conducive to adjusting the data and has a unique and neat style.For no-load impulse closing of transformer,ZakapaPower transformer specification, pay attention to the following matters:Zakapa,Transformer manufacturers said that at this stage, China's energy-saving distribution transformer market is relatively scattered, coupled with the constraints of factors such as low threshold in the field, uneven companies, lack of evaluation and specifications, and inadequate technical innovation, resulting in slow marketing of energy-saving transformers.After no-load test run is normal for h, it can be transferred to on-load operation, % and % by grade.Kribi,For no-load impulse closing of transformer, pay attention to the following matters:The bearing capacity of each load is different. Generally, dry-type transformer should operate under rated capacity, while oil transformer has better load working capacity.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 insulation distance between the winding and the iron yoke of power transformer is much larger than that between the windings, because the electric field between the winding and the iron yoke is far away and not as symmetrical as that between the windings. In the electric field in the middle of the winding,ZakapaOil immersed regulator, most of the cables are in phase with the insulating cylinder (plate) in the middle of the winding, that is the disconnection component of the electric field is small.What is the cause of power transformer core failure?Analysis of common faults of oil immersed transformer:Finance Department,Oil leakage at electric welding positionFor no-load impulse closing of transformer, pay attention to the following matters:If you want to check the activated carbon fiber for the hanging cover, first take out the low-voltage waterproof sleeve and the on load transformer power switch, then lower the bell cover anchor bolt of the large cover,ZakapaPeriodic voltage regulator for maintenance of oil immersed transformer, slowly hang the galvanized steel wire rope with sufficient lifting net weight on the commonly used earrings wear round steel from top to bottom in the surrounding screw holes, and count the spacing and specifications for easy reinstallation. At the same time, stop the lifting, stabilize the bell cover, and check the bearing capacity of the lifting core, center of gravity and Jack. After everything is normal, lift it again until the bell cover exceeds the relative height of the body, the actual operation of the oil immersed transformer shall be undertaken by the on-site operation and maintenance management staff. Within one week of grid connected operation, the operation and maintenance management staff shall improve the safety inspection range of the transformer, and immediately communicate and contact with the on-site project staff in case of any problems, so as to ensure the reliable and stable operation of machinery and equipment.Inspection basis,Power transformerThere is a magnetic induction line crossing in the transformer core, which will cause induced electromotive force on the plan with the magnetic induction line. Because this electric flow creates a closed loop to generate an electric field and forms a vortex, it is called vortex. The existence of vortex makes the transformer core hot and consumes kinetic energy. This kind of loss is called vortex loss.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.ZakapaOperation of oil immersed transformerHow to reduce the failure of dry-type transformer?The plastic shells of electrical products and office supplies are equipped with grounding wires. If the insulation layer is damaged and the shell is energized, the electric flow will leak into the earth along the installed grounding wires, so as to achieve the purpose of safety, otherwise it will have an adverse impact on life safety.
