Design concept of power transformer

Due to the low saturation magnetic flux density of amorphous alloy materials, the rated magnetic flux density should not be too high during product design. A flux density of 1.3–1.35T is generally suf

Installation process of power transformers

A transformer is a common electronic component and electrical device. It can be used to transform an alternating voltage of a certain value to an alternating voltage of another value with the same fre

Protection selection for power transformers

Transformers of 800KVA and above should, in addition to installing gas relays and protection circuits, have appropriate overcurrent and instantaneous overcurrent protection in the system circuit; sett

Power transformers should be maintained regularly.

Main contents include: Removing defects found during inspections, cleaning porcelain bushing casings, replacing cracked or aged gaskets, checking and tightening connection points, replenishing oil whe

Inspection methods for power transformers

When all personnel are on duty at the substation, an inspection should be conducted once per shift. If no one is on duty, an inspection can be conducted weekly. Special inspections should be increased

The main types of power transformers are:

Contains silica gel. The insulating oil in the oil conservator (oil pillow) is connected to the atmosphere through the desiccant. The desiccant absorbs moisture and impurities from the air to maintain

Power supply method of power transformer

Most user transformers use a Yyn0 connection configuration with a directly grounded neutral system, enabling three-phase four-wire or five-wire power supply, such as the TN-S system.

The function of power transformer

Power transformers are one of the main pieces of equipment in power plants and substations. Transformers serve multiple functions: they not only raise voltage to deliver electrical energy to the user

Working principle of power transformer

When a 220/110/35kV transformer uses a YN, yn0, d11 connection, and a 110/35/10kV transformer uses a YN, yn0, d11 connection, the voltage phasors of these two 35kV transmission systems differ by an el
