What are the losses of the transformer?
The transmission of the magnetic field is accompanied by loss, which can be divided into the following situations: Eddy current losses Faraday said that a changing magnetic field can generate electricity, and Lenz said that this kind of electricity will hinder the change of the magnetic field, which is called Back EMF. The magnetic core […]
Overview The vacuum oil filtration machine must work in a vacuum state. The higher the working vacuum, the stronger the ability to analyze moisture and gas. Due to different types of filtered oil, the vacuum degree requirements are also different. That’s why ASSEN designed both Single-stage and Double-stage Vacuum Oil Filtration Machine, to meet different […]
8 things you should know about transformer vacuum filling,standing and hot oil circulation Regarding transformers with voltage levels of 60KV and above, transformer vacuum filling, standing and hot oil circulation should be carried out when the transformer body is exposed to moisture, overhaul, and new installations. Transformer Vacuum Filling 1.Control value of vacuum degree during […]
How to consider a suitable oil pump for a vacuum oil dehydration plant? Vacuum Oil Dehydration Plant’s Oil Pumps 1. Determination of the type of oil pump: oil pumps commonly used in vacuum oil purifiers can be divided into gear pumps, centrifugal vane pumps and plunger pumps according to their structure. a). Gear pumps are […]
1.Press Plate Oil Filter unit(purifying hydraulic oil) It is composed of a primary filter, oil pump, and press components. The primary filter is a cylindrical metal mesh, which can prevent the larger solid particles in the unqualified oil from entering the oil pump. The oil pump is usually a gear pump, which transports unqualified oil […]
What caused the lower breakdown voltage? The measurement of the lower breakdown voltage of insulating oils, especially the time of their aging, is an important task to evaluate the degradation of these liquids used for the transformer isolation. According to observe the picture below, we can see that the breakdown voltage reduces with increasing aging […]
