the tightening bolts are loose, and the installation and processing process is wrong, so that the bolts are not tightened well resulting in oil leakage.Oil leakage at looper flangeHaining,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.How much is the power transformerTensberg,Before no-load impulse closing, the transformer shall be placed for h, and the rising seat and waterproof sleeve installed with vent plug shall be deflated on time.Power transformer is one of the key equipment in power station and substation. The function of power transformer is in all aspects. It can not only raise the voltage and send electromagnetic energy to the power consumption area, but also reduce the voltage to each application voltage, so as to meet the needs of power consumption. In short,HainingElectrical equipment transformer, voltage transformation and blood pressure reduction must be carried out by the transformer.Operation and maintenance management of oil immersed transformer

The power transformer is designed according to the temperature protection scheme. The embedded parts in the material layer of high (low) pressure electromagnetic coil poured with integral concrete are provided with longitudinal ventilation duct, which can be equipped with air-cooled machinery and equipment (cooling centrifugal fan). After selecting air-cooled machinery and equipment, the output capacity can be increased by %.During the operation of the transformer, the resistance value of the grounding wire shall be measured accurately every two years.Falling foreign matters and piercingDiscount,Performance and main parameters of common metal composites,HainingPrice of 1000 KVA transformer, various welding processes and machinery and equipment, preparation treatment of thick steel plate, blanking process production and manufacturing process and quality standards of automobile oil tank, riser, coupling and oil storage tank cabinet, welding leakage test and NDT technology,HainingModel of power dry-type transformer, surface treatment process and quality standards, copper, Production process and quality standard of aluminum shield; Body suit iron insertion process, wire installation process, body dryness solution and dry transformer oil solution process, vacuum pump oil immersion, general installation process, leakage test and leakage detection process and quality standards. Performance parameters of key work clothes, machinery and equipment of each process flow; The natural working environment is basically regulated.When the manufacturer of the power transformer samples from the automobile oil tank after opening the sealing cover, use the cleaned and dried rubber stopper to the oil. At the same time, clamp the branch pipe with your thumb, and loosen your thumb to make the oil enter the pipe,The clock expression is used to indicate the phase difference correlation of the working voltage of the secondary side line. The phasor of the working voltage of the primary side line is used as the minute hand, the fixed finger is at o'clock, and the phasor of the phase voltage of the secondary side is used as the second hand.

When oil samples are used, the safety and fire safety technical specifications on the spot shall be strictly implemented.Where can I find it?,Fault judgment of power transformerThe proper selection of Anhui dry-type transformer has a key effect on improving the safety and smooth operation of power system software. In the above original text, we will describe how to select dry-type transformer according to the load characteristics and application environment of dry-type transformer.Loose core screwHaining, 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?The switching power supply lacks one phase of power;Manufacturing process and steps of dry-type transformer
