If the insulation layer is damaged and the shell is energized, the electric flow will leak into the earth along the installed grounding wires, so as to achieve the purpose of safety otherwise it will have an adverse impact on life safety.
Dry type transformer manufacturer
Gonzalez Villa.The common dry-type transformer is an important electrical equipment, and the voltage is constantly regulated. However, the dry-type transformer will also boost voltage, and the whole process of boosting voltage is very complex, and there are many principles.
Insulation and heat removal are different. Dry type transformers are generally insulated with epoxy resin, cooled by natural air and large capacity by centrifugal fan. Oil immersed transformers are insulated by insulating oil, insulated by insulating oil in the circulating system inside the transformer,Gonzalez VillaOperating temperature range of dry-type transformer,Gonzalez VillaMaintenance system of oil immersed transformer, and heat is discharged on the radiator (radiator) of the circulating system inside the transformer.
.Power transformer
There are many connection groups of dry-type transformers, and the selected structures and connections are also different. Then, what are the groups of dry-type transformers? How to carry out the connection? Or basically introduce it with the network of dry-type transformer manufacturers.
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.
The no-load impulse closing working voltage shall not exceed 5% of the working voltage marked on the gear of the transformer, the closing frequency shall be 5 times, the delay time after power receiving shall not be less than 10min, and the time interval of each closing shall not be less than 5min.
The insulation of the through core anchor bolt clamping the iron core is damaged, resulting in a short circuit fault between the silicon steel sheet of the iron core and the through core anchor bolt;
Gradually, high-frequency vibration damping mechanical equipment, such as low-frequency vibration damping platform, is installed at the bottom of the dry-type transformer,Gonzalez VillaPower transformer model definition, etc. with flexible connection roads, 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.
Create brilliance.Method and process of taking oil sample of power transformer
Power transformers are also used for testing, which are called test power transformers. They can be divided into inflatable, oil transformer, dry test and other test power transformers. They are the basic test equipment for communication AC compression test for many consumers such as power stations, power supply bureaus and scientific research institutions. According to the specifications of the Bureau of quality supervision, It is used to carry out insulation compressive strength test under required current for various electrical products, electrical components and insulating raw materials.
Dry type transformer manufacturer
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, the operation and maintenance management staff shall improve the safety inspection range of the transformer, and the selected structures and connections are also different. Then so as to ensure the reliable and stable operation of machinery and equipment.
Honesty is the foundation.There are many connection groups of dry-type transformers, what are the groups of dry-type transformers? How to carry out the connection? Or basically introduce it with the network of dry-type transformer manufacturers.
In order to better avoid overvoltage damage, a group of overvoltage maintenance high-voltage Arresters (such as y4cs active zinc oxide high-voltage arresters) shall be refitted at the working voltage bus duct side of dry-type transformer.
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.
Gonzalez Villa.The oil in the machinery and equipment of the oil storage tank shall generally stand for more than 8h before sampling; it is not necessary to stand when sampling on the running power transformer.
Oil leakage of cast iron parts
From the appearance, the packaging types are different. The transformer core and electromagnetic coil can be seen immediately for dry-type transformer, and only the shell can be seen for oil immersed transformer;
