SilversonThreeThe power transformer conductor refers to the connecting transmission line between each electromagnetic coil, between the electromagnetic coil and the group outlet pipe, and between the electromagnetic coil and the tap changer.
What is the wavelength of oil immersed transformer?
Kalukumbe.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.
For the installation of lightning rod, it is very easy to damage the relay protection inside and outside of dry-type transformer by lightning. If it is a serious situation, it is very easy to cause fire accidents, power failure, damage to machinery and equipment,KalukumbeMaximum capacity of box transformer, etc.
.When the new oil filled by the power transformer and the oil sample that has just been considered are used, the oil sample can be used only after sufficient standing.
The switching power supply lacks one phase of power;
35kV and above & plusmn; No load of rated voltage; Part of the circuit breaker of the tap power switch is installed in the phenolic resin insulating paper cylinder,Kalukumbe500 kV oil immersed transformer, and the insulating paper cylinder is installed on the wooden frame. The actual operation rocker is connected with the dynamic circuit breaker of the tap power switch according to the wooden insulating rod. The on load tap off power switch is insulated from the ground by the insulating paper cylinder of the power switch itself and the insulating limit.
The electromagnetic coil is wound with copper power wire or foil and lifted with glass fiber. The epoxy adhesive does not need filling. The vacuum drying equipment is used for degassing and dehumidification. The overall concrete is poured with high fracture toughness, resistance to short-circuit faults, common faults and impact. The work is diligent.
Automatic system of centrifugal fan: measure the temperature data signal according to the PT100 thermistor temperature measuring resistor of the embedded parts at the hot part of the bottom pressure winding. The transformer load expands and the operating temperature increases. When the winding temperature reaches 110 ℃ the system software automatically starts the centrifugal fan for refrigeration; When the winding temperature is as low as 90 ℃, the system software will automatically terminate the centrifugal fan.
Dry type transformer manufacturer
Installation conditions.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.
Power transformer is one of the key equipment in power station and substation. The function of power transformer is in all aspects. It can not only raise the voltage and send electromagnetic energy to the power consumption area,KalukumbePower plant step-up transformer, but also reduce the voltage to each application voltage, so as to meet the needs of power consumption. In short, voltage transformation and blood pressure reduction must be carried out by the transformer.
Protective measures for damping of dry-type transformer
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, please pay attention during maintenance. It is not necessary to destroy the insulation. After maintenance, experts can inspect special tools, parts, insulation etc. and deliver them after they are determined to be complete and reliable.
Online consultation.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.
Several detection methods for installing transformer
When sampling from a small and medium-sized power transformer without a discharge pipe (or oil sample suspension plate), or it can be replaced by changing the oil.

Deterioration damage of transformer core insulation
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.
