Zhengzhou10kV oil immersed distribution transformerCurrent status of product technical equipment

Common problems of tap changer of power transformerWhen sampling from a small and medium-sized power transformer without a discharge pipe (or oil sample suspension plate), it can be in a power transformer such as a glass test tube when it is not in operation to extract the oil sample at the bottom, or it can be replaced by changing the oil.Zhengzhou,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;The method and whole process of taking oil sample of power transformer are as follows:MtinkoSound, causing short circuit obstruction. If not handled properly, it will cause great damage.Gradually, high-frequency vibration damping mechanical equipment, such as low-frequency vibration damping platform, is installed at the bottom of the dry-type transformer, which can reduce the downward dispersion of the vibration of the dry-type transformer. Then replace the connection between the dry-type transformer and the surrounding engineering buildings, roads, etc. with flexible connection, or use elastic yellow shock absorption mechanical equipment to prevent the vibration from spreading according to the rigid connection. If possible, the dry-type transformer room can also be soundproofed and decorated, and sound-absorbing plates and silencing shutters can be used to improve the soundproofing capacity of the dry-type transformer room.In the case of using dry-type transformer, customers must master the method of wiring. If there are problems in wiring, it is easy to cause common faults in application. So, what is the wiring mode of dry-type transformer?

What is the wavelength of oil immersed transformer?In order to promote the use of energy-saving transformers, the Ministry of industry and information technology and the national development and Reform Commission jointly promulgated the detailed rules for the implementation of energy-saving distribution transformers of energy-saving products benefiting the people project as early as , providing subsidies of - yuan / KVA for energy-saving transformers.Operation and maintenance management of oil immersed transformerquality,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.(III) dry type transformers of KVA and below can be installed on poles. The distance between its bottom end and the road surface shall not be less than m; The distance between the electrified part and the road surface shall not be less than m.If the above provisions are not met, the problem of dryness shall be solved. Generally, it is OK to operate the centrifugal fan for a period of time. Check the cleanliness of the power transformer. If too much dust is found it must be eliminated to ensure indoor ventilation and avoid insulation penetration. In particular,ZhengzhouHow much is 200 KVA oil transformer, such as ventilation duct, and there shall be no dirt.

Analysis of common faults of oil immersed transformer:Professional is king,When the full load test is carried out and everything is normal, the load can be connected.First of all, although dry-type transformer has strong moisture resistance, it is generally open structure or very susceptible to moisture,ZhengzhouPeriodic voltage regulator for maintenance of oil immersed transformer, especially the insulation level of dry-type transformer manufactured in China is low (lower flame retardant grade) Therefore the dry-type transformer can obtain high stability only when the air humidity is below %. The dry-type transformer shall also be prevented from stopping operation for a long time to prevent serious damp. When the grounding resistance value is less than / V (operating voltage), it indicates that the transformer is seriously damp, and the trial operation shall be terminated.When sampling in bulk gasoline barrels, samples shall be selected according to % of the number of gasoline barrels,ZhengzhouInstallation scheme of 35 kV oil immersed transformer, but not less than barrels. When sampling in batches of small and medium-sized pails or bottles, samples shall be taken according to % of the total number of barrels (bottles).Zhengzhou,After the test, connect the data signal contact of the automobile relay with the alarm circuit, the pull-in contact with the opening circuit, and adjust the overcurrent protection value.In the whole process of transmitting electromagnetic energy in the power supply system, the voltage loss is inversely proportional to the voltage, and the output power loss is inversely proportional to the square meter of voltage. The transformer is used to increase the voltage and reduce the closing damage.Dry type transformer manufacturer
