OlsenOil immersed transformerWhat are the outstanding problems in the industry

When the new oil filled by the power transformer and the oil sample that has just been considered are used, the oil sample can be used only after sufficient standing.Dry type transformer oscillation is solved by applying vibration damping platform to dry-type transformer and carrying out low-frequency vibration reduction management, which can control the oscillation below .%, and then reduce the building structure noise transmitted by dry-type transformer oscillation.Olsen,The cycle time of power-off cleaning and inspection shall be determined according to the surrounding environment and load conditions generally from half a year to once a year;When the power transformer operates at full load, it needs a large reactive load. This reactive load shall be provided by the power supply and distribution system. If the transformer volume is too large, it will not only increase the initial project investment,Olsen400 KVA price of box type transformer,Olsen315 KVA oil immersed transformer, but also make the transformer operate at full load or load for a long time, expand the proportion of full load loss, reduce power factor and increase Internet loss. Such operation is neither economic development nor scientific.Kailuwan,Loose core screwWhat is the wiring mode of dry-type transformer?Due to poor sealing, generally, the sealing of box edge and machine cover is sealed with acid-base resistant rubber rod or rubber plate. If the joint is not solved well, it will lead to common faults of oil leakage.

The manufacturing process of dry-type transformer is very process, and must be technically as a certain pillar. Only in that way, the performance of dry-type transformer will be more stable. What are the common manufacturing processes and steps of dry-type transformer?Power saving analysis of transformerPower transformers are used in all walks of lifeTest method,The switching power supply lacks one phase of power;() the installation position of secondary commercial insurance of transformer on column and ground shall meet the following requirements: if there is an disconnector on the secondary side, it shall be installed between the disconnector and low-voltage composite insulator, or the circuit breaker shall be selected as the disconnector; If there is no disconnector on the secondary side, it shall be installed on both sides of the low-voltage composite insulator, and the insulated cable jumper shall be connected to the insulated cable on both sides of the circuit breaker.When the screw of the through core extruder holding the iron core of the transformer is loose, there are screw cap parts left on the iron core, or small metal materials fall into the transformer, the transformer will send out & ldquo; Ding Ding Dang & rdquo; Or & ldquo; Call & hellip; Call & hellip& rdquo; Blowing sound and its & ldquo; Squeak,OlsenPower transformer impedance, squeak & rdquo; It's like a magnet sucking a small washer, while the working voltage, current and temperature of the transformer are all normal. Such conditions generally do not endanger all normal operation of the transformer, and can be solved until power failure.

Sound, causing short circuit obstruction. If not handled properly, it will cause great damage.AdministrationPower transformer is an idealized supporting facility transformer for medium cabinet and high-voltage cabinet at the present stage, commerce and can be equipped with safety protective casing according to different waterproof grades. It is applicable to key or unique natural environment sites such as multi-storey buildings, airports, tunnel construction, chemical enterprises and factories.The common dry-type transformer is an important electrical equipment, and the voltage is constantly regulated. However, because of certain necessity, the dry-type transformer will also boost voltage, and the whole process of boosting voltage is very complex, and there are many principles.The conductor insulation of power transformer is the main part of internal insulation. Some conductors should pass through the middle of electromagnetic coil, or between electromagnetic coil, iron yoke clamp and automobile oil tank wall. Therefore, i.e. insulation spacing.Olsen,Wiring mode of dry-type transformer:It will also produce many faults, effectively deal with various faults of oil immersed transformer, make full use of the performance indicators and advantages of oil immersed transformer, and continuously improve the safety factor of oil immersed transformer. Ignition is a common fault of oil immersed transformer. The key fault of oil immersed transformer is short-circuit fault
