When using the oil sample of the power transformer in operation, it is necessary to add some oil from the oil gate valve at the lower part of the oil tank or the sampling gate valve to release about 2kg of waste liquid stored at the bottom to clean the oil inlet, and then take the oil sample.
Linbei.In fact, apart from the application of the Finance Bureau, the industry has been trying to formulate and upgrade transformer commodities according to the specifications, so as to promote the improvement of energy consumption level of transformer commodities.
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, and immediately communicate and contact with the on-site project staff in case of any problems, dry-type transformers are mostly used in & ldquo; Fireproof and explosion-proof type & rdquo; It is easy to use in large and medium-sized engineering buildings and multi-storey buildings; The oil immersed transformer because of & ldquo; Accident & rdquo; There is likely to be oil or leakage after fire and most application places leading to fire accidents are easy to choose in large and medium-sized engineering buildings and multi-storey buildings;
The power transformer belongs to relatively durable electrical equipment, power transformer winding and power transformer tapping power switch are analyzed below:
If the oil immersed transformer is burned by the cover of the transformer and we can't neglect it in daily application. The common problems of power transformer conductor, when the oil immersed transformer fails, open the lower side of the transformer and place an appropriate part. When the oil immersed transformer is on fire, the oil cannot be released to avoid the occurrence of the oil immersed transformer. At the same time, use detection equipment to put out the fire immediately. In order not to expand the hazard, the fire brigade must be notified.
Careless maintenance and insulation damage
In order to promote the use of energy-saving transformers, the Ministry of finance, 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 2012, providing subsidies of 4-30 yuan / KVA for energy-saving transformers.
What is the reason for the shutdown of power transformer?
Test conclusion.Avoid inadvertent damage of insulation during maintenance: when repairing the hanging core of power transformer, special attention shall be paid to the maintenance of solenoid coil or insulating waterproof sleeve. If there is scratch damage, it shall be handled properly.
Wiring mode of dry-type transformer:
The vibration reduction of collecting and townhouse solves the soft connection of collecting and townhouse. For the copper bar of the low-voltage bus of the equipment,LinbeiMaximum allowable temperature of oil immersed transformer, the electromagnetic induced noise oscillation may be transmitted from the townhouse to the building structure. The core of noise reduction solution must be changed to copper wire connection.
What is the wiring mode of dry-type transformer?
The cost is reasonable.In specific daily life, oil immersed transformers are released outward in the form of waves. This kind of wave is like a tide. It is also a kind of kinetic energy. In fact, the wave height of oil immersed transformer also shows the size of kinetic energy. Generally, computer automatic system is used to control the wavelength and frequency of electromagnetic wave. The longer the light wavelength is, the greater the output power is. On the contrary, it is very small.
The efficiency of transformer is closely related to the output power level of transformer. Generally, the smaller the loss to output power ratio and the higher the efficiency. On the contrary, the smaller the output power,LinbeiElectrical equipment transformer, the lower the efficiency.

Linbei.What is the wiring mode of dry-type transformer?
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, but also make the transformer operate at full load or load for a long time,LinbeiVarious models of transformer, expand the proportion of full load loss, reduce power factor and increase Internet loss. Such operation is neither economic development nor scientific.
Generally speaking, the ignition emergency treatment method of oil immersed transformer is mainly to disconnect the oil immersed transformer, disconnect the switching power supply on each side, quickly invest the reserved oil immersed transformer and start the power supply system from scratch. Stop the operation of refrigeration equipment. Key oil immersed transformer ignition. When L-type oil immersed transformer and high voltage station oil immersed transformer are ignited, the generator set must be disassembled first.
