net friendPoweA zero line of the power transformer is connected with the working equipment. Since the voltage formed by the server during operation will be sent to the power transformer along with the cable,Kanpur800 dry type transformer quotation, the power transformer will be transported and sent to the power consuming machines and equipment. What is the zero line of the actual power transformer? Let's introduce it to us.
After the test, the pull-in contact with the opening circuit, and adjust the overcurrent protection value.
Kanpur.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.
After sampling, bind the laminated glass stopper firmly with clean paper or cloth to prevent dirt and water from contaminating the bottle stopper.
.After the oil is drained, all anchor bolts of the automobile oil tank at the upper end of the detachable oil cover shall be tied with the lifting jack, and the lifting point shall be on the common earrings or bolts. If necessary, the human resources traction belt shall be used as a guide.
Power transformer plant
The power transformer is designed according to the temperature protection scheme. The embedded parts in the material layer of high (low) pressure electromagnetic coil poured with integral concrete are provided with longitudinal ventilation duct, which can be equipped with air-cooled machinery and equipment (cooling centrifugal fan). After selecting air-cooled machinery and equipment, the output capacity can be increased by 20%.
On load commissioning:
After the power transformer has been used for a long time, common faults of iron core will occur. Don't worry. Contact the transformer manufacturer, and the manufacturer will assign professional technicians for inspection. The main reasons are as follows:
The flange surface is uneven, the tightening bolts are loose, and the installation and processing process is wrong,KanpurOil immersed self cooling transformer, so that the bolts are not tightened well, resulting in oil leakage.
Information recommendation.Deterioration damage of transformer core insulation
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.
Loose core screw
The key reason for oil leakage is that there are defects in cast iron parts
agent.It is generally made due to unreasonable installation or ineffective sealing. Polymer composite materials can bond metal materials, laminated glass and other materials very well, so as to achieve the pressure management of oil leakage.
Power saving analysis of transformers has always been based on whether the utilization rate of transformer capacity is less than a certain standard value. Whether transformers are environmental protection and energy saving specifications. In fact, sometimes such specifications are not saving electromagnetic energy, but consuming electromagnetic energy.
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.
Kanpur.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 and short-circuit fault is more general.
Before no-load impulse closing, the transformer shall be placed for 24h, and the rising seat and waterproof sleeve installed with vent plug shall be deflated on time.
When checking the hook core, the insulation of the electromagnetic coil and the porcelain sleeve is usually accidentally damaged. After the shell of the pottery is broken, if you work again, turn on the photo flash when it's light, and it's short when it's heavy. Therefore, please pay attention during maintenance. It is not necessary to destroy the insulation. After maintenance,KanpurRecycling power transformer, experts can inspect special tools, parts, insulation, etc. and deliver them after they are determined to be complete and reliable.
