Victoria de Las Tunas500KVA price of power transformerBasic knowledge of operation
The scientific research of power transformer oil is generally carried out according to the way of sampling. What are the common sampling methods and processes?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, most of the cables are in phase with the insulating cylinder (plate) in the middle of the winding, the disconnection component of the electric field is small.Victoria de Las Tunas,Dry type transformer is a common electrical equipment, which can be used to convert the alternating voltage of one standard value into another standard value of the same frequency. The step-up dry-type transformer is used to convert the low-grade alternating voltage into another high-grade alternating voltage of the same frequency. It is widely used in high-frequency industries, such as variable frequency power supply.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.Eger ,Under normal conditions, 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,Victoria de Las Tunas3000 oil immersed 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.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, floating concrete floor damping pad and other sound insulation and noise reduction commodities to achieve sound insulation effect.The no-load impulse closing working voltage shall not exceed % of the working voltage marked on the gear of the transformer,Victoria de Las TunasNormal operating temperature of dry-type transformer, the closing frequency shall be times, the delay time after power receiving shall not be less than min, and the time interval of each closing shall not be less than min.
How to reduce the failure of dry-type transformer?Visual inspection method for transformer inspectionSolenoid insulation deteriorationProject scope,When oil samples are used, the safety and fire safety technical specifications on the spot shall be strictly implemented.When checking the hook core the insulation of the electromagnetic coil and the porcelain sleeve is usually accidentally damaged. After the shell of the pottery is broken, if you work again, turn on the photo flash when it's light and it's short when it's heavy. Therefore,Victoria de Las TunasVoltage transformer, please pay attention during maintenance. It is not necessary to destroy the insulation. After maintenance, experts can inspect special tools, insulation, etc. and deliver them after they are determined to be complete and reliable.The vibration reduction of the grounding device sheet solves the problem of modifying the fixed hard connection between the copper sheet of the grounding device and the dry-type transformer. The original oscillation of the dry-type transformer will be transmitted to the metal in the concrete by the baffle and cause low-frequency noise. Therefore, it must also be changed to produce flexible connection.
A specific part of dry-type transformer is the hanging core of dry-type transformer. The hanging core of dry-type transformer is a vital component. How to carry out the hanging core?Focus on Development,Outdoor sampling shall be carried out in sunny days or dry weather with low environmental humidity. During sampling, it is necessary to resolutely prevent the invasion of dirt such as rain, snow, wind and sand.Transformer isHow much is the power transformerVictoria de Las Tunas,Under normal conditions, 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.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.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.
