MahendranagaHothe 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.
After no-load test run is normal for 24h, it can be transferred to on-load operation, and the load shall be gradually increased from 25%, 50% and 75% by grade.
adrenaline.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.
Power transformer
.It includes the performance and main uses of insulating layer materials, various insulating layer parts, component manufacturing processes and quality standards; Performance and main uses of various wires,adrenalineMain transformer and distribution transformer, coil inductance process of various ways of electromagnetic coil, solution process and quality standard, overall suit process and quality standard of electromagnetic coil; Main performance parameters of ferrite core, cutting process of iron chip, core stacking process and quality standard, production process and quality standard of electromagnetic shielding.
Dry type transformer manufacturer
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, the human resources traction belt shall be used as a guide.
The noise of dry-type transformer is mainly the vibration noise in operation. This vibration noise is caused by multiple positions, including the vibration of magnetic induction electromagnetic coil. All pay great attention to the solution of vibration when carrying out noise control.
There is a magnetic induction line crossing in the transformer core,adrenalineDry type 1250kva transformer, 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.
Noise dispersion of dry-type transformer
Industry management.The bearing capacity of each load is different. Generally,adrenalineTypes of dry-type transformers, dry-type transformer should operate under rated capacity, while oil transformer has better load working capacity.
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, odor and other abnormal conditions. If there is any abnormality, please cut off the input switching power supply.
Different diversion methods, dry-type transformers mostly use silica gel waterproof casing while oil transformers mostly use porcelain waterproof casing;
Power transformers are also used for testing, which are called test power transformers. They can be divided into inflatable, oil transformer, power supply bureaus and scientific research institutions. According to the specifications of the Bureau of quality supervision, It is used to carry out insulation compressive strength test under required current for various electrical products, electrical components and insulating raw materials.
offer.The cross-sectional wiring of transformer input and output power plugs shall comply with the provisions of their current size; It should be equipped according to the current intensity of 2-5A / Min2.
Protection mode for type selection of dry-type test transformer
Brief introduction of zero line of power transformer
adrenaline.Caused by sand holes and cracks. For crack leakage, drilling stop hole is a good way to remove in-situ stress and prevent widening.
Dry type transformer manufacturer
When oil samples are used, the safety and fire safety technical specifications on the spot shall be strictly implemented.
