Avianeda partyMaintenance of box transformerHow to distinguish the direction of rotation

Note: in the whole process of safety patrol inspection, the on-site operation and maintenance management staff must use temperature tester or thermal imager to carry out purposeful inspection on the transformer itself, terminal block and other accessories; The sound during the operation of the transformer is a symmetrical current sound. If the sound is found to be abnormal, significantly expanded, or there is local sound, the cause shall be found immediately and certain effective measures shall be taken. If necessary, if the oil immersed transformer catches fire 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?

.Noise dispersion of dry-type transformer

Naturally, please don't panic. I firmly believe that the damage will be reduced to a lower level as long as the above methods are effectively rectified. Above is the general process and process that should be paid special attention to in the whole ignition process of the oil immersed transformer. When the oil immersed transformer catches fire, please be rational to make the oil immersed transformer safer and more efficient.

In order to better carry out the experiment of power transformer oil, it is necessary to sample the power transformer oil. The sampling work should be carried out on a dry sunny day. The commonly used containers and sampling methods during sampling do immediate harm to whether the specific quality of the oil can be truly reflected. The oil sample for AC voltage withstand test shall not be less than 0.5kg, and the oil sample for simplified experiment shall not be less than 1kg.

Dry type transformer factory

Two point grounding device of iron core caused by residual welding scar;

With the rapid development of society and the continuous development trend of computers, the accuracy of calculation conclusions can meet the needs of architectural design,Avianeda partyPrice of 100 KVA dry type transformer, and scientific and reasonable data method is selected, which greatly facilitates the design scheme of the oil immersed transformer and ensures the stability of operation.

quality standard.Before application but also the winding and other structures of the oil immersed transformer can be effectively arranged and distributed in a certain scope, the sampling container shall be cleaned with vehicle gasoline, soapy water or other organic solvents (such as trisodium phosphate) except oil stains, and then washed with tap water until it is not alkaline, and the water can be evenly distributed from the bottle, and then cleaned with purified water for many times. The cleaned sampling container shall be dried in a 105 ℃ drying oven. After refrigeration, the bottle cap shall be tightly closed and cannot be opened before application.

Oil leakage at looper flange

Insulation and heat removal are different. Dry type transformers are generally insulated with epoxy resin, cooled by natural air and large capacity by centrifugal fan. Oil immersed transformers are insulated by insulating oil, insulated by insulating oil in the circulating system inside the transformer, and heat is discharged on the radiator (radiator) of the circulating system inside the 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, 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.

production costs.What is the wavelength of oil immersed transformer?

Oil sample inspection & mdash; & mdash; the performance parameters such as compression resistance and residue shall be carried out every three years. The long-term overload or overload of the transformer can reduce the cycle time.

Deterioration damage of transformer core insulation

Avianeda party.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,Avianeda partyIndoor installation of oil immersed transformer, ignition, odor and other abnormal conditions. If there is any abnormality,Avianeda partyPrice of 200 KVA transformer, please cut off the input switching power supply.

Sound insulation treatment of main engine room the key to sound insulation treatment of dry-type transformer room is to start from three levels: window, ventilation and air exchange port and road surface, and apply sound insulation window, silencing cylinder, floating concrete floor damping pad and other sound insulation and noise reduction commodities to achieve sound insulation effect.
