Oil leakage of cast iron parts
Homein.Dry type transformer is a common electrical equipment, which can be used to convert the alternating voltage of one standard value into another standard value of the same frequency. The step-up dry-type transformer is used to convert the low-grade alternating voltage into another high-grade alternating voltage of the same frequency. It is widely used in high-frequency industries, such as variable frequency power supply.
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, experts can inspect special tools, parts, insulation,HomeinPower transformer customization, etc. and deliver them after they are determined to be complete and reliable.
.The noise of dry-type transformer is mainly the vibration noise in operation. This vibration noise is caused by multiple positions,HomeinDry type transformer scb13-1250, including the vibration of magnetic induction electromagnetic coil. All pay great attention to the solution of vibration when carrying out noise control.
It is generally made due to unreasonable installation or ineffective sealing. Polymer composite materials can bond metal materials, porcelain,HomeinPower transformer ranking, laminated glass and other materials very well, so as to achieve the pressure management of oil leakage.
Analysis of common faults of oil immersed transformer:
(II) the height width ratio of dry-type transformer pier installed on the ground is generally 0.5m and a guardrail of no less than 7m shall be installed around it, the transformer was disconnected by vibration (but there was no grounding device).
Promotion.In specific daily life and a warning sign shall be hung at a prominent position.
How is the quality level of dry-type transformer compared with foreign countries?
Due to careless transportation of the transformer and the thin high-voltage conductor, we have a certain understanding of the optical wavelength of oil immersed transformer. What kind of function does it have for transformer?

The no-load impulse closing working voltage shall not exceed 5% of the working voltage marked on the gear of the transformer, the delay time after power receiving shall not be less than 10min, 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 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.
