MahendranagaHoHow to reduce the failure of dry-type transformer?
Noise solution of dry-type transformer
Winnipeg .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.
When oil samples are used, the safety and fire safety technical specifications on the spot shall be strictly implemented.
.Falling foreign matters and piercing
The main reason is that the welding quality of electric welding is poor, there are empty welding, needle holes, sand holes and other shortcomings in welding. The oil transformer is easy to be covered with welding powder and paint when leaving the factory, and the potential safety hazards are exposed after operation. In addition, the electromagnetic induction vibration will crack the electric welding and lead to leakage.
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, 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.
Oil leakage of heat pipe radiator
Under normal conditions, different oil-based oils cannot be mixed. Under special circumstances, if it is necessary to use new oil of different grades, it should be determined whether the mixed oil with ice degree can be used according to the requirements of the region, and then the oil mixing test should be carried out.
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, 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.
project.The key reason for oil leakage is that there are defects in cast iron parts
The cross-sectional wiring of transformer input and output power plugs shall comply with the provisions of their current size; It should be equipped according to the current intensity of 2-5A / Min2.
What is the wavelength of oil immersed transformer?
When the transformer is out of phase, if the second phase is blocked, there is still no sound when the second phase is sent,Winnipeg Price list of 250kVA box type transformer,Winnipeg 2000 KVA power transformer, and there is sound when the third phase is sent; If the third phase is blocked the sound will not change, as in the case of the second phase. There are three reasons for phase deficiency:
Process inspection.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.
Power transformer is indispensable for power stations and substations, but we must pay attention to many problems in the whole process of applying power 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, expand the proportion of full load loss, reduce power factor and increase Internet loss. Such operation is neither economic development nor scientific.
Winnipeg .Some are tied with plastic tape,Winnipeg How to select power transformer, because the socket can not be pressed firmly during installation, and there is still oil leakage without sealing effect.
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?
Oil leakage of porcelain pot and laminated glass oil level gauge
